And even being crypted on the filesystem once decrypted the private key will stay in memory unencrypted all the time. If someone breaks in the machine while it is running he/she will get the key from memory not from the filesystem. The only use of crypted private keys (for deamon-services) I can think of is that you can prevent someone from stealing your private key if he/she steals physically the harddisk or the whole machine from your server-room. And even this has the major disadvantage that the service will not start without human intervention (the private key's passphrase input) after unexpected reboots. -----BEGIN PGP SIGNATURE----- iD8DBQFCuVvWFw6SP/bBpCARAuTEAJ0bdKAURvMh4VZA7QEXplNYySrxTQCgoOBH XY4ftFyPqY36xDdZww6kSFU= =2/nK -----END PGP SIGNATURE-----

Having encrypted private_key.pem and a plain text file private_key.pem.passphrase which contains the encryption password really does not make any sense. Ofcourse both files should be chown root and chmod 400. -----BEGIN PGP SIGNATURE----- iD8DBQFCumGtFw6SP/bBpCARAp52AJ9cOGOgwTqnuDN82ubkU5Vk3uieWgCdHQSS tBmrJ3voYiHwD9hJOwtwocM= =+cCS -----END PGP SIGNATURE-----

GUI for openssl certificate generation
by Paul Jones 22 Jun '05

22 Jun '05

Hi all, I'm looking at building a small GUI app (possibly in VB6) on a Windows platform for generating certificates using OpenSSL. How can I do this? The command-line call to the openssl EXE does not seem to take things such as the Common Name, Organizational Unit, etc as parameters. Any help would be appreciated. Thanks in advance.

a suggestion for release announcement

Hello Michal, thank you for your excellent software! I have a little suggestion: Could you include release files' MD5 and SHA hash codes or your pgp signature in the release announcement? That should be more reliable, should it? -- Regards Lu Wei

Stunnel crashing
by David Gomel 21 Jun '05

21 Jun '05

I have been having some major problems trying to secure pop3 and imap with stunnel. I am running a RHEL3 box with Cpanel. I first started off by installing a clean copy of stunnel 4.10 but it was causing numerous bizarre problems. 1) it would crash after a few hours of the daemon operating, 2) before it would crash I would be getting tons of 'mailbox locked' errors and 3) the occasional timeout connecting. I eventually gave up with 4.10 and decided to try to use the stunnel 4.04 that was already doing https for cpanel/whm. I created a separate config file and ran a separate daemon just for pop/imap (I did this because I want them to be using different SSL certs). This seemed to be working perfectly as there were no timeouts, no locked mailbox errors and it didn't seem to be crashing. After about 24 hours however, the process had shut down. I tried a few more times and again after about 12-24 hours of running my pop/imap only stunnel daemon crashes. I should also mention 2 other things: 1) prior to having set up 4.10 on my box, stunnel 4.04 was listening for pop/imap without crashing (it just wasn't being used however). 2) The other daemon running https for cpanel/whm hasn't crashed at all. I've included the log (level 7) for everything that happened in the 1-2 seconds before it crashed. If anyone could offer any advice, it would be greatly appreciated! Thanks!

I use stunnel for testing and compare results with our products. I made a script to monitor the number of threads and memory per process, now it always show 1 thread.

Stunnel and Sun Calendar 5
by Michael Chanudet 17 Jun '05

17 Jun '05

Hi, I'm using stunnel with Sun Calendar on a Windows 2003 server. Everything works well until I'v move Sun Calendar on an other server. Now, when I go to my Sun Calendar, I need to refresh the page after having accepted the certificat. You can see the problem here => https://frodon.atnweb.com I'm using stunnel 4.10 libeay32.dll and libssl.dll version 0.9.7.3 (from openssl.org) My conf file looks like this: ------------------------------- key = E:\stunnel\stunnel.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 3 output = E:\stunnel\stunnel.log [https] accept = 443 connect = 80 TIMEOUTclose = 0 -------------------------------- If someone can see where is the problem, I will be pleased to know the answer :) Thanks, Regards, Michaël CHANUDET atn groupe sa 2 allée des Mitaillères - 38240 Meylan - France Tél. : +33 (0)4.76.41.17.17 - Fax : +33 (0)4.76.41.05.45 www.atngroupe.fr

CVS version of the FreeBSD port of stunnel can be found at: http://www.freebsd.org/cgi/cvsweb.cgi/ports/security/stunnel/ the files/ subdir contains some changes to the original source. Some of them are FreeBSD specific and need only be applied on FreeBSD, but some are not. Changes to client.c are related to execvp problems. http://www.freebsd.org/cgi/cvsweb.cgi/ports/security/stunnel/files/patch-sr… can be useful. Changes to common.h are a hack to make it possible for the user to choose ucontext/pthread/fork model at compile time. Log message can be found at: http://www.freebsd.org/cgi/cvsweb.cgi/ports/security/stunnel/files/patch-sr… It was invented as a workaround to the ucontext-problems, but is a good feature anyway. I think it will be great if someday we can use ./configure options like - --with-ucontext, --with-pthread, --with-fork, instead of using this ugly hack :) Regards, Vasil -----BEGIN PGP SIGNATURE----- iD8DBQFCsQ7pFw6SP/bBpCARAo3wAKDbu0lXx0+LMW31dksb4S8M74PukQCgwmwx KH0/Ohi+GtUwBSbYv8RkLsg= =wzW2 -----END PGP SIGNATURE-----

Fix unexpected stunnel-4.10 exits on FreeBSD

It will be good if we see this (or similar) fix in the next version of stunnel. The problem is that we cannot (at least on FreeBSD): 1. create context A (cleanup context) 2. create context B and set B's uc_link to point to A 3. swapcontext(3) to B What happens is that B's function returns, A's function passes control to the main thread of execution 4. create context C and set C's uc_link to point to A What happens is that A is exhausted and this will not work as expected 5. swapcontext(3) to C We expect A's function to be executed after C's function returns, but instead exit(3) is called when A's function returns and the whole program terminates normally after serving its second request. -----BEGIN PGP SIGNATURE----- iD8DBQFCrcgJFw6SP/bBpCARAll9AKCPTyMK23v28h8eGKW0LQw7RjrWFgCfWHjR BQEEDOOx/mGG7S38QhqLIW8= =yB1z -----END PGP SIGNATURE-----

Setting up Stunnel on Server AND Clients
by Peter Pentes 14 Jun '05

14 Jun '05

G'Day all, I'm having trouble understanding how to incorporate Stunnel into a client/server environment. There is a application running on the server which receives and sends data to various clients. The clients also have a communications application running. None of the apps (on both server and clients) support any form of encryption. So I want to use Stunnel for this. How would I set Stunnel up on the server and also the clients? I can't find an example on stunnel.org that discusses such a scenario. Any help would be great. Cheers.

Registering other dlls after running Stunnel
by andym＠rhotrading.com 13 Jun '05

13 Jun '05

I'm having a problem registering other dlls that depend on tibco and ws2_32. I could register them fine prior to putting stunnel on and now they are problematic. Trying regsvr32 returns nothing; not an error or a success. I can successfully install and uninstall this same dll on a different system that does not have Stunnel on it. Windows platform (XP). Has anyone else run into behavior like this and/or does anyone have any suggestions to troubleshoot. I've verified that the dll is not being registered silently by searching the registry. I spoke with a developer who said that Stunnel might be hooking in on my dlls registry attempt and causing it to blow up. Any thoughts? Thank you, Andy

How to Remove Stunnel From Start-Up?
by mhrtmhd94＠att.net 13 Jun '05

13 Jun '05

I have finally been able to delete and successfully re-install Stunnel, which I am using in conjunction with Agent. There are still some problems, which I think are more related to Agent, and I am consulting with Agent tech support. However, there is one problem with Stunnel. It starts when I boot into Windows (XP SP2). I did not intend for Stunnel to run except when I launch it along with Agent. How can I remove it from Start-Up? Stunnel DOES NOT appear under the Start-up tab when I run msconfig. If it is necessary to uninstall Stunnel and reinstall it, is there a convenient way of doing so? I had a helluva time doing this and eventually was able to accomplish it by deleting as many Stunnel entries as I could from the registry. Thanks. Mort Middleman

RE: [stunnel-users] stunnel on HP-UX
by Stephen Tanner 12 Jun '05

12 Jun '05

The PRNG in HP-UX does not start until rc3. The normal place for syslog to start is in rc2, so I had placed stunnel and syslog-ng in rc2 for startup. I simply moved the startup script for PRNG to rc2. -----Original Message----- From: Dan Langille [mailto:dan@langille.org] Sent: Friday, June 10, 2005 10:08 AM To: Stephen Tanner Cc: stunnel-users(a)mirt.net Subject: RE: [stunnel-users] stunnel on HP-UX On 10 Jun 2005 at 10:04, Stephen Tanner wrote: > Please disregard, I have located the issue.

Stunnel --- communication + encryption in both directions
by Paul Jones 12 Jun '05

12 Jun '05

Hi, I am interested in using Stunnel, but I am a little confused currently. The "Forwarding an insecure port securely from one machine to another" (http://www.stunnel.org/examples/generic_tunnel.html) example only discusses the situation for sending data from the server to the client (i.e. a single direction). How would stunnel have to be set up so that encrypted communication is achieve in both directions? That is, from server to client and also from client to server? Imagine that there is an application running on one end, and an identical app running on the other end and neither supports encryption. So I want to bring stunnel into the picture, so that communication is encrypted/decrypted on both ends. Cheers.

Hi Folks, I'm trying to run configure to cross compile, my host machine is linux and my target is mips hardard (mvista) I get the following configure errors: checking for /dev/ptmx and /dev/ptc cannnot check for file existence when cross compiling I poked around in the configure.ac and see there these are defined. What is the purpose for checking for the existence of this files? And... what flags should I be providing to configure? Thanks! Kramer

Compression (zlib) does not work under windows
by Ben 09 Jun '05

09 Jun '05

Hello, Enabling zlib compression in stunnel (versions 4.06 - 4.10) does not work under windows. I have tried a combination of the following, all of which have failed in either two ways. The first way being disconnection with the following messages in the stunnel console: 2005.06.09 11:43:10 LOG7[4072:3088]: SSL alert (write): fatal: decompression failure 2005.06.09 11:43:10 LOG3[4072:3088]: SSL_read: 1408F06B: error:1408F06B:SSL routines:SSL3_GET_RECORD:bad decompression Or stunnel crashes all together. Here are the following combinations I've used with stunnel and openssl. stunnel 4.06 w/ all zlib binary openssl libraries stunnel 4.07 w/ all zlib binary enabled openssl libraries stunnel 4.08 w/ all zlib binary enabled openssl libraries stunnel 4.09 w/ all zlib enabled openssl libraries stunnel 4.10 w/ all zlib enabled openssl libraries stunnel 4.06 w/ custom compiled openssl 0.9.7g w/ zlib library under vc++ stunnel 4.07 w/ custom compiled openssl 0.9.7g w/ zlib library under vc++ stunnel 4.08 w/ custom compiled openssl 0.9.7g w/ zlib library under vc++ stunnel 4.09 w/ custom compiled openssl 0.9.7g w/ zlib library under vc++ stunnel 4.10 w/ custom compiled openssl 0.9.7g w/ zlib library under vc++ Under linux, using stunnel as a client, compression works correctly.

We offer stunnel connections as a service to our clients to reduce the overhead of NNTP traffic and we would very much like to get compression working. Thanks for your time, Ben

Reinstalling Stunnel
by mhrtmhd94＠att.net 07 Jun '05

07 Jun '05

I followed the Agent/Stunnel instructions on WURD. I reached the point where I added a space, followed by -install to the shortcut target path. When I attempted to execute this, a message appeared: "Failed to create a new service." I want to thank all those who answered my previous request. I am hoping that someone with experience using Stunnel in conjunction with Agent might be able to help me. I can't for the life of me figure out what I did differently from the first time I installed Stunnel to run with Agent. One person who replied to my previous request asked if I had uninstalled the previous installation of Stunnel. The only way I could do this was to delete all of the programs in the Stunnel directory, because Stunnel does not appear on the list of programs under Add and Delete Programs via Control Panel. Note: I originally was using version 4.07. I am now attempting to use version 4.10. Could this be the problem? Thanks in advance to anyone who can help.

There are no specific daemons that need to run. Network is practical for DNS resolving if that's needed.

stunnel on HP-UX
by Stephen Tanner 07 Jun '05

07 Jun '05

I'm running stunnel on a HP-UX 11.11 system so that I can securely transfer logs with syslog-ng. I have stunnel and syslog-ng both starting in rc2.d at S537. Every time I have rebooted the server I get a broken pipe as if stunnel is having an issue establishing a tunnel, and I am forced to restart stunnel and syslog-ng. Are there any specific daemons that need to be running before stunnel starts? I'm trying to avoid having this start too late, so that I don't miss logs on some daemons. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Stephen Tanner HP-UX Systems Administrator Network Support Services Lee County Clerk of Courts =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Reinstalling Stunnel
by mxrtmxd72＠att.net 06 Jun '05

06 Jun '05

I followed the Agent/Stunnel instructions on WURD. I reached the point where I added a space, followed by -install to the shortcut target path. When I attempted to execute this, a message appeared: "Failed to create a new service." I want to thank all those who answered my previous request. I am hoping that someone with experience using Stunnel in conjunction with Agent might be able to help me. I can't for the life of me figure out what I did differently from the first time I installed Stunnel to run with Agent. One person who replied to my previous request asked if I had uninstalled the previous installation of Stunnel. The only way I could do this was to delete all of the programs in the Stunnel directory, because Stunnel does not appear on the list of programs under Add and Delete Programs via Control Panel. Note: I originally was using version 4.07. I am now attempting to use version 4.10. Could this be the problem? Thanks in advance to anyone who can help. Mort Middleman

[PATCH] Fix inetd mode
by Miloslav Trmac 05 Jun '05

05 Jun '05

Hello, the attached patch fixes inetd mode. signal_pipe[] is not used in inetd mode, so it was left default-initialized to {0, 0}. Emptying "the pipe" would eat all input data. The second hunk was already posted here by Michal Trojnara. Mirek

slightly OT: starting up multiple instances
by Colin McKinnon 01 Jun '05

01 Jun '05

Hi all, I realise this is slightly OT (the problem seems to be in a different program) but thought that someobdy out there may have solved this one already. I'm trying to run a second instance of stunnel (different 'verify' level) on a SuSE 8.2 box. The second instance just doesn't start. What I did was to copy the supplied /etc/init.d/stunnel script to 'stunnelv' and referenced different config and PID files. After I had fixed bug in the startup script (the line which started the process - using startproc - didn't pass the conf file, and didn't get told to use the PID file) I still got the same error. Now, if I run '/etc/init.d/stunnel start' I get /var/run/stunnel.pid. If I then run '/etc/init.d/stunnelv start' it reports 'OK' but didn't really start. If I start them the other way around 'stunnelv' works and I get /var/run/stunnelv.pid but then 'stunnel' won't start. Thinking that 'startproc' is seeing 'stunnel' already running in the processlist, I tried creating a symbolic link '/usr/sbin/stunelv' to /usr/bin/stunnel and changed '/etc/init.d/stunnelv' to run that instead of '/usr/sbin/stunnel'. Looking in 'ps' it is reported as 'stunnelv' but I still can't get the second instance to start. The error seems to be with 'startproc' - it seems to think that the intended process is running when it's not. If I just type in the line which starts up stunnel as shown below I get the same behaviour. startproc -v -l /var/log/rc.stunnelv.log -p /var/run/stunnelv.pid /usr/sbin/stunnelv /etc/stunnel/verified_clients.conf Unfortunately, the '-v' option doesn't seem to work. Anybody any suggestions? TIA, Colin

[PATCH] Reject inetd mode with no client specification
by Miloslav Trmac 01 Jun '05

01 Jun '05

Hello, when stunnel is started in inetd mode without specifying connect = nor exec =, it attempts to execl(NULL) and the child SIGSEGVs. The attached patch adds a check to reject such configurations. Mirek

I installed (actually re-installed) Stunnel. I got as far as creating the shortcut as follows: c:\stunnel\stunnel-4.10.exe -install. The message "Failed to Create a New Service" appeared. I need some help. Thanks.

Patch: verify_depth and remote_subj
by Michael Smith 26 May '05

26 May '05

Hi, I've attached a patch against stunnel 4.10. It adds two verification options to the global configuration: === remote_subj = expected subject for the remote certificate If set, the remote certificate's subject must match this string. You can obtain the subject in the proper format by running openssl x509 -in servercert.pem -noout -subject Example: remote_subj = /C=CA/ST=Ontario/CN=gw Requires verify=2 or greater. verify_depth = maximum number of CA certificates in chain Specifies the maximum certificate chain depth when verifying the peer certificate: 0: peer certificate must be self-signed 1: peer certificate must be signed by a root CA 2: peer certificate can be signed by at most one intermediate CA The stunnel default depth is 9 for backwards compatibility. Please note that Apache/SSL defaults to 1. If your non-CA certificates are marked with the X509v3 basic constraint "CA:FALSE", you probably do not need to worry about chain depth. This is the default behaviour for most CA tools, including the scripts that ship with OpenSSL. === remote_subj probably belongs in per-service config, not global, but the SSL verification setup is global and I didn't want to start messing with it.

Upstream Connect
by Justin Alexander 25 May '05

25 May '05

Is there a way with stunnel for a client to connect to a server (hopping a firewall), forming a secured SSL/TCP connection, that will allow the server to connect back to the client machine over that tunnel? So far, all I've read is that stunnel only allows connections to start on the client and connect down stream (through the tunnel) to the server. I need to reverse this pattern.

Re: unexpected shutdown of stunnel

Hi, For what it's worth: >I use Freebsd and made an update from stunnel 4.8 to stunnel 4.10 from >the ports today. Now I noticed that stunnel stops after a while. > > I experienced the same, only my configuration ran in server- instead of client-mode. The only thing that I did while building the port was using -DWITH_IPV6, but I assume that shouldn't be a problem. >And these are the last lines of the log:005.05.15 10:34:00 > > I used debug = 5, and I didn't see anything usefull in the logs. I'm glad someone has the same problem and has better logging then I have ;-) The last log line was the incoming session, that's it. >Everything went fine with 4.8, now stunnel is not running anymore after >a short period of time (few minutes). > > I'm back to the 4.7 we had previously. We're using this in production, so I couldn't really experiment much with the 4.10. Regards, Paul

CN field of server cert
by spambox＠poczta.onet.pl 16 May '05

16 May '05

Hi stunnel-users, There is example configuration:  I don't know how to enforce stunnel to verify CN field from server provided certificate. Even if i change "connect" field to next one stunnel will not complain. So, am I wrong that when someone hijack (mitm) this connection and provide any server cert signed by ThawteServerCA then I loose? Please add this verification to stunnel when verify is set to 2 or better as an separate option "verify_cn?" which could be used in service-level context. Usting this option with that described below I can drop 'verify' and 'CAfile' at all and feel much better. :) There is another verification method that could be added - not related to verify option. In most cases I know public cert of remote server. So I also know sha1/md5 fingerprint of that cert. Security could improve v.much by just adding these lines to my example configuration: fingerprint_md5=F5:BD:C3:C8:D5:4B:03:EA:57:BB:81:72:46:6B:26:54 fingerprint_sha1=CE:3A:0D:3E:DA:4B:77:A3:53:C0:9E:A8:65:B7:F8:C2:09:71:43:41 Another good service-level option? There are some other good options that could be ported from openssl/s_client: "-ssl2, -ssl3, -tls1, -no_ssl2, -no_ssl3, -no_tls1" Regards.

Hello, I use Freebsd and made an update from stunnel 4.8 to stunnel 4.10 from the ports today. Now I noticed that stunnel stops after a while.

Problems with stunnel 4.10 compilation
by Oleg Ivanov 14 May '05

14 May '05

Hello. I've compiled stunnel 4.10 without any problems on my Gentoo workstation and RedHat server. But now I need to install it into my old legacy Mandrake 8.2 server and here I've got into troubles. I've updated zlib and openssl (configuring it with "zlib" option) to their latest versions, then tried to make stunnel and got following errors: --- /usr/lib/libcrypto.a(c_zlib.o): In function `zlib_compress_block': c_zlib.o(.text+0x48): undefined reference to `compress' /usr/lib/libcrypto.a(c_zlib.o): In function `zz_uncompress': c_zlib.o(.text+0x145): undefined reference to `inflateInit_' c_zlib.o(.text+0x159): undefined reference to `inflate' c_zlib.o(.text+0x16c): undefined reference to `inflateEnd' c_zlib.o(.text+0x18b): undefined reference to `inflateEnd' collect2: ld returned 1 exit status make[1]: *** [stunnel] Error 1 make: *** [all-recursive] Error 1 --- It seems like problems with zlib so I've double-checked it - but zlib 1.2.2 is really installed. If I recompile openssl without "zlib" option then I can make stunnel but it can't initialize zlib compression algorithm that I really need. And if I compile openssl with zlib - stunnel fails on make with errors. Can anyone help with it please?

Connection details patch for 4.10
by Oleg Ivanov 14 May '05

14 May '05

Hello. I've modified the old "conndetails_peter" patch by Peter D. Gray to let it work with stunnel 4.10. I've also added to it information about compression (available compression methods and negotiated method). Patch creates a file "conn.LOCAL_HOST:LOCAL_PORT" in a configurable temp directory (config file: "infodir" option). The file is deleted when the client disconnects. Full description of original can be found at: http://www.stunnel.org/patches/desc/conndetails_peter.html Hope it will be useful for someone.

syslog on Solaris2.9
by Geoff LeBoldus 13 May '05

13 May '05

I can't seem to get stunnel-4.10 to log properly to syslog. Stunnel logs the startup, but doesn't log any individual tunnel information. If I specify its own file and debug = 7, it logs everything as expected. I've tried a number of different configuration combinations without success. Any thoughts?

And to set a value for session timeout do I use the option: session = timeout session cache timeout Thanks, Vasudha. -------------------------------------------- Vasudha Upadhyaya Convergys Speech Solutions Ph:703-885-5837 vasudha.upadhyaya(a)convergys.com -- "NOTICE: The information contained in this electronic mail transmission is intended by Convergys Corporation for the use of the named individual or entity to which it is directed and may contain information that is privileged or otherwise confidential.

zlib compression
by Oleg Ivanov 09 May '05

09 May '05

Hello. I have installed stunnel 4.09 both as client (on my computer) and as server (on server). Both has zlib compression enabled and I can see that zlib initializes properly in the logs (it says "Compression enabled using zlib method"). But when I send any data over that tunnel I can't see any signs of compression - amount of traffic is almost the same as over plain connection. Am I doing something wrong? Or I'm misunderstanding the purpose of this compression ability? And if the traffic indeed must be reduced - why I can't see that and how can I make it work properly? Thank you for your answers. Best Regards, Oleg Ivanov. -- Oleg Ivanov mailto: saruman(a)unigsm.com

connect ip = accept ip on multihomed server ?
by Dennis Spreen 09 May '05

09 May '05

hi all, with a configuration (stunnel4.10) like this [conc1] accept = 100 connect = 99 stunnel accepts all requests on all ips on port 100 but connects with the localhost to port 99. is it possible to configure stunnel that if it accepts a connection on 1.2.3.4:100 it connects to 1.2.3.4:99 ? I know it is possible to use accept = 1.2.3.4:100 connect = 1.2.3.4:99 .... accept = 1.2.3.250:100 connect = 1.2.3.250:99 but i'm on a c-class and that would require about 250 entries in the config file. Is there a better way to do this? regards dennis

Problems in Stunnel4.10
by vasudha.upadhyaya＠convergys.com 06 May '05

06 May '05

Hi, We have been using stunnel 4.05 and recently downloded the stunnel 4.10 and deployed in our environmrnt. All the traffice is going via the Load Balancer Cisco CSS with SSL Module to the unix server(with stunnel4.10 on them). We also 4.10 deployed on the Windows2000 as a client. The CSS sends keep Alives to check the health of the servers(whether they are up or not).And I guess due to this the stunnel on unix servers crashes immediately and there is a access violation error. Attached is the truss output for one of the unix servers.Stunnel4.10 was compiled using OpenSSL0.97d and OpenSSL0.97g, and still we get the same problem.Attached is the stunnel.conf also.[attachment "stunnel.conf" deleted by Vasudha Upadhyaya/CCMG/CVG] (See attached file: truss.out) (See attached file: stunnel.conf) Thanks, Vasudha. -------------------------------------------- Vasudha Upadhyaya Convergys Speech Solutions Ph:703-885-5837 vasudha.upadhyaya(a)convergys.com -- "NOTICE: The information contained in this electronic mail transmission is intended by Convergys Corporation for the use of the named individual or entity to which it is directed and may contain information that is privileged or otherwise confidential.

Can anyone point me to some documentation on how to use mingw to patch and make stunnel? Specifically, I want to apply connect-proxy_dunbar.patch to v4.05 source and compile it. As I am not really a coder (yet) and am not yet very *nix knowledgeable, any help would be much appreciated. Situation is: I am trying to traverse a MS ISA server (running as a proxy) and the v4.10 stunnel doesn't allow me to specify a proxy to route thru. Thanks in advance, Geoff __________________________________ Do you Yahoo!? Yahoo! Mail - Find what you need with new enhanced search. http://info.mail.yahoo.com/mail_250

I have compiled and installed stunnel 4.10 under Mac OS X 10.3. I want to set up stunnel to connect a non-ssl newsreader client to an ssl nntp server. The newsreader client is Unison and the server is Easynews SSL server. I don't really know how to do this. I wonder if anyone can point me in the right direction. Thanks Geoff ___________ PS I did various searches of the list archive and read TFM, but still need guidance!

ldaps error "unknown protocol"
by Mike Partyka 29 Apr '05

29 Apr '05

Hello, Description of problem is as follows: I have a email server package called Scalix, which when installed came with openldap. On the same server i am also running Stunnel, which is already successfully ssl wrapping imap,pop, and smtp protocols. The ldap directory is very handy for an address book internally but we also have people that will be outside the corporate lan and to provide the directory securely would be desirable so i added the lines in the stunnel.conf to wrap ldap as well. I can see the stunnel daemon listening on port 636. But when i try to connect from any ssl aware mail client, such as evolution, or entourage, i get an error indicating failure to authenticate, which i know is not really the problem because the ldap directory is anonymous read access enabled. Debug logging gives more information about what is occurring, here is the conversion when attempting to connect: 2005.04.28 12:15:05 LOG5[27926:1076812720]: ldaps connected from 71.4.124.200:43012 2005.04.28 12:15:05 LOG7[27926:1076812720]: SSL state (accept): before/accept initialization 2005.04.28 12:15:05 LOG7[27926:1076812720]: waitforsocket: FD=14, DIR=read 2005.04.28 12:15:05 LOG7[27926:1076812720]: waitforsocket: ok 2005.04.28 12:15:05 LOG3[27926:1076812720]: SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol 2005.04.28 12:15:05 LOG7[27926:1076812720]: ldaps finished (6 left) Searching the archive is saw someone suggesting that either the ldap server or ldap client was not compiled with ssl support. I know the email clients i am trying to connect with are ssl compatible and maybe someone can set me straight here but i didn't think that the ldap server had to be ssl aware and that was the advantage of stunnel is that it can wrap services that are do not have ssl support? At any rate i believe the ldap server does have ssl support becuase i can see the binary omslapd (provided by Scalix, preceding "om" is there because Scalix is based on HP's Open Mail) links to the ssl library using the ldd command, here is the output, note the bolded line: msp1intmx01:~ # ldd /opt/scalix/bin/omslapd linux- gate.so.1 => (0xffffe000) libom_er.so => /opt/scalix/lib/libom_er.so

stunnel crash when multiple connections
by Debin Chen 27 Apr '05

27 Apr '05

Hi, I will appreciate greatly if you can diagnose the following crash problem: I am using stunnel 4.05, working with webserver thttpd to provide a https solution, in linux environment. First I wrote down some noticeable behavior of stunnel. 1) stunnel each time spawns a thread to handle the https connection then destroy the thread. If I browse a lot of pages, then internally a lot of thread ( or process) got created and destroyed. 2) Sometimes after a https request is completed, the thread is still there. Only following request will trigger the thread got destroyed. Normally if there is no activity, just 2 threads left. The problem: During some stress testing, such as multiple ( in my case, actually just 2 or 3) web browser simultaneously issues request to the web server in https, I found out in certain moment stunnel spawns more than 5 or 6 threads to handle the connections, sometimes it crashed without giving out any serious debug error messages. When it crashed, system resource of CPU and memory is still sufficient. Note than I already set timeoutclose=0, that should be done.

Hello, Sorry for the newb question, but I've done quite a bit of searching and haven't found a definitive answer either way - and I doubt I'm the first to ask about this. Is there any way to connect an incoming connection directly to a unix domain socket? Some sort of service level option like: connect = /path/to/socket would be ideal, and hopefully I'm just missing something in the docs. If this is not available, I can just exec socat - but that seems like an unnecessary step. Thanks much, Marty

I'm trying to implement a secure TCP tunnel from one PC to another. I've been looking for quite some time and can't seem to find the problem. I've been following the following example of how to start a server service: stunnel -p /path/to/stunnel.pem -d pop3s -r bar:pop3 I've created a generic certificate, but I get the error: Failed to open configuration file -p What am I doing wrong??

Patch: Windows version of stunnel 4.09 is not thread-safe
by yi.lin＠convergys.com 23 Apr '05

23 Apr '05

We have been using stunnel on Windows as a SSL proxy to connect to HTTPS server but stunnel kept crashing randomly under load. After some investigation, we found the following: according to OpenSSL document (http://www.openssl.org/docs/crypto/threads.html), "OpenSSL can safely be used in multi-threaded applications provided that at least two callback functions are set. locking_function(int mode, int n, const char *file, int line) is needed to perform locking on shared data structures. (Note that OpenSSL uses a number of global data structures that will be implicitly shared whenever multiple threads use OpenSSL.) Multi-threaded applications will crash at random if it is not set. " The original stunnel package only implements a POSIX Pthread version of locking callback functions, but doesn't provide any implementation for Windows. This has caused random crashes during our testing because the way we use stunnel requires frequent creation/destruction of threads and stunnel is not thread-safe without the locking callbacks. The attached fix attempts to address the problem by implementing the Windows version of locking callbacks using Windows native CRITICAL_SECTION object. =============================================================================================================================== *** sthreads.c Fri Dec 31 02:55:40 2004 --- sthreads_w32.c Thu Apr 14 08:29:07 2005 *************** *** 121,126 **** --- 121,127 ---- #ifdef USE_WIN32 CRITICAL_SECTION stunnel_cs[CRIT_SECTIONS]; + static CRITICAL_SECTION lock_cs[CRYPTO_NUM_LOCKS]; void enter_critical_section(SECTION_CODE i) { EnterCriticalSection(stunnel_cs+i); *************** *** 130,141 **** --- 131,161 ---- LeaveCriticalSection(stunnel_cs+i); } + static void locking_callback(int mode, int type, + #ifdef HAVE_OPENSSL + const /* Callback definition has been changed in openssl 0.9.3 */ + #endif + char *file, int line) { + if(mode&CRYPTO_LOCK) + EnterCriticalSection(lock_cs+type); + else + LeaveCriticalSection(lock_cs+type); + } + + void sthreads_init(void) { int i; /* Initialize stunnel critical sections */ for(i=0; i<CRIT_SECTIONS; i++) InitializeCriticalSection(stunnel_cs+i); + + /* Initialize OpenSSL locking callback */ + for(i=0; i<CRYPTO_NUM_LOCKS; i++) + InitializeCriticalSection(lock_cs+i); + CRYPTO_set_locking_callback(locking_callback); + + } unsigned long stunnel_process_id(void) { (See attached file: sthread_diff) Yi Lin Convergys Corporation yi.lin(a)convergys.com (703)885-5767 -- "NOTICE: The information contained in this electronic mail transmission is intended by Convergys Corporation for the use of the named individual or entity to which it is directed and may contain information that is privileged or otherwise confidential.

Disabling IPv6

Hello Everyone !! I need to build Stunnel-4.09 in HP-UX11.11 without the support of IPv6. I did not use --enable-ipv6 option. In the configure log I could see the reference of getaddrinfo and getnameinfo functions. Is that refers any of the system file or the function defined in the souce code? I used `nm stunnel | grep getaddrinfo` and it shows the following. $ nm stunnel | grep getaddrinfo getaddrinfo | |undef |code | getaddrinfo | 118768|uext |stub | $ I need to confirm the source(from where they are taken) of getaddrinfo and getnameinfo functions. Is that related with the support of ipv6 in any way? Any of you please make me clear. Thanx in ADVANCE. Regards, Punitha.

stunnel generating defuncts
by Serxio Barral 19 Apr '05

19 Apr '05

Hi there! I'm using stunnel as client with SuSE SLES 8. Usually after several days working OK (up to two weeks) it begins to generate defunct processes for every transfer. At first, stunnel version was 3.14 (the one that comes out of the box with SLES 8), but now I have downloaded an compiled 3.26 and it just happens the same. killing stunnel won't help, since relaunching it again turns on generating defuncts. Situation does not come back to normal until rebooting the server. Any hint on this issue? Thanks in advance, Serxio Barral.

Please Help! I keep getting the same error.
by Theodore W. Hildebrandt 11 Apr '05

11 Apr '05

Refer to my submission of 03/24/05: "error:1408F10B:SSL . . . " I had hoped that someone would tell me how to get around this error, but no message has appeared in the stunnel Archive. I have now ftp'd version 4.09 and tried it, with the same results. I wait and wait for a connection, and finally interrupt the process, since it's not going anywhere. And then I get the "error:1408F10B. . ." message in the stunnel log. Since I seem to be able to send e-mail from my old Pentium II computer (Windows 98SE) I'm, using it so send this message. [Note that I can still receive e-mail on the new Dell Pentium IV machine (Windows XP Home). I just can't send anything.] Doesn't anyone have answers? Ted Hildebrandt

Unexpected closed connections
by Rory Campbell-Lange 11 Apr '05

11 Apr '05

Hi Everyone We have been very happily using stunnel for about 5 months connecting a site office back to a main office, tunnelling imap connections. We are suddenly seeing lots of disconnection messages and people at a. can no longer see their mail on d. The server suffers a "socket write shutdown" condition and shuts down the associated process. We have restarted the routers and firewalls and all seems to be working fine, other than stunnel. I'd be grateful for any insight or further help.

Occurs when I upgraded from stunnel 4.08 to 4.09. Using OpenSSL 0.9.7f .

stunnel and NNTP on windows - best practices
by Sir Thanksalot 08 Apr '05

08 Apr '05

Hi all, I am trying to use stunnel for SSL access to a NNTP newserver and found quite a few pages that list ways of doing that. I personally am using xnews as my newsreader, and I have seen variations of the same instructions with different software (Agent, Free Agent for newsreaders, Pegasus Mail as your mail application etc.). For completeness sake, here are some of the ones that I've found - http://www.cotse.net/users/putty/ssl (for Xnews and stunnel 4.x) http://www.geocities.com/d4vidb/x_setup13.html (for Xnews and stunnel 3.x - doesn't use the stunnel.conf file necessary in stunnel 4.x) http://www.noderunner.net/~llin/old/nntp-ssl.html (for a newsreader and stunnel 3.x. It also has links to a stunnel.conf file for stunnel 4.x users) In all these instructions (whether using the stunnel 3.x commandline options or using the stunnel.conf file for stunnel 4.x), I haven't seen any instructions about creating any certificates or public/private keys or a passphrase. Also there doesn't seem to be any writeup on what algorithm actually ends up getting used or even a way to pick which algorithm to use. What's the best practise for users? Should they do anything extra? Set up key pairs? Choose a default algorithm? Thanks. -- _______________________________________________ NEW! Lycos Dating Search.

TIMEOUTclose
by Joe Abbey 08 Apr '05

08 Apr '05

Background: I have been having issues getting Entourage to connect with my mail server over POP3S. Entourage will connect, communicate, and then hangs for 60 seconds. According to tcpdumps, Entourage appears to hang until a timeout. Connecting directly to the pop3 daemon, bypassing stunnel, there is no lag. Therefore something appears to be wrond with the stunnel/Entourage interaction. To get Entourage to work with POP3S and have virtually no lag, I've set in my stunnel.conf TIMEOUTclose = 2 for [pop3s]. Question: Is there any reason not to set TIMEOUTclose = 0? Thanks! Joe

stunnel 4.09 problem: Connection rejected: too many clients
by Steven Van Acker 04 Apr '05

04 Apr '05

Hi, after upgrading to stunnel 4.09, we are having 2 problems with it that did not exist in a previous version (our case: stunnel 4.05 without pthreads) ---[ My testsetup is as follows: * stunnel listening on port 4321, connects to localhost port 13 (daytime) * daytime is enabled in inetd * stunnel was compiled without pthreads * ulimit -u = 8192 ---[ problem 1 At first, it works fine. For every incoming connection, the process forks and data is transferred. However, when the connection is closed, the forked process remains hanging for a while (about 1 minute) and then exits. This in itself is not a real problem, except that it generates a lot of processes. (and maybe causes problem 2 ?) ---[ data and logs concerning problem 1 (process hangs for 1 minute): I run the following command: openssl s_client -connect 192.168.2.119:4321 the output follows immediately The logfile (debug = debug) looks like this: 2005.03.31 14:05:05 LOG7[4552:0]: daytime accepted FD=8 from 192.168.2.103:47200 2005.03.31 14:05:05 LOG7[4552:0]: FD 8 in non-blocking mode 2005.03.31 14:05:05 LOG7[4553:0]: daytime started 2005.03.31 14:05:05 LOG5[4553:0]: daytime connected from 192.168.2.103:47200 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): before/accept initialization 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read client hello A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write server hello A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write certificate A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write server done A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 flush data 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read client key exchange A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 read finished A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write change cipher spec A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 write finished A 2005.03.31 14:05:05 LOG7[4553:0]: SSL state (accept): SSLv3 flush data 2005.03.31 14:05:05 LOG7[4553:0]: 1 items in the session cache 2005.03.31 14:05:05 LOG7[4553:0]: 0 client connects (SSL_connect()) 2005.03.31 14:05:05 LOG7[4553:0]: 0 client connects that finished 2005.03.31 14:05:05 LOG7[4553:0]: 0 client renegotiatations requested 2005.03.31 14:05:05 LOG7[4553:0]: 1 server connects (SSL_accept()) 2005.03.31 14:05:05 LOG7[4553:0]: 1 server connects that finished 2005.03.31 14:05:05 LOG7[4553:0]: 0 server renegotiatiations requested 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache hits 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache misses 2005.03.31 14:05:05 LOG7[4553:0]: 0 session cache timeouts 2005.03.31 14:05:05 LOG6[4553:0]: SSL accepted: new session negotiated 2005.03.31 14:05:05 LOG6[4553:0]: Negotiated ciphers: RC4-SHA SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=SHA1 2005.03.31 14:05:05 LOG7[4553:0]: FD 7 in non-blocking mode 2005.03.31 14:05:05 LOG7[4553:0]: daytime connecting 127.0.0.1:13 2005.03.31 14:05:05 LOG7[4553:0]: connect_wait: waiting 10 seconds 2005.03.31 14:05:05 LOG7[4553:0]: connect_wait: connected 2005.03.31 14:05:05 LOG7[4553:0]: Remote FD=7 initialized 2005.03.31 14:05:05 LOG7[4553:0]: Socket closed on read 2005.03.31 14:05:05 LOG7[4553:0]: SSL write shutdown 2005.03.31 14:05:05 LOG7[4553:0]: SSL alert (write): warning: close notify 2005.03.31 14:05:05 LOG7[4553:0]: SSL_shutdown retrying 2005.03.31 14:05:06 LOG7[4553:0]: SSL alert (read): warning: close notify 2005.03.31 14:05:06 LOG7[4553:0]: SSL closed on SSL_read 2005.03.31 14:05:06 LOG7[4553:0]: Socket write shutdown When I check netstat, the connection from the client to stunnel is in the CLOSE_WAIT state and the connection from stunnel to the daytime server is in TIME_WAIT state then 1 minute later, this follows: 2005.03.31 14:06:06 LOG6[4553:0]: s_poll_wait timeout: connection close 2005.03.31 14:06:06 LOG5[4553:0]: Connection closed: 26 bytes sent to SSL, 0 bytes sent to socket 2005.03.31 14:06:06 LOG7[4553:0]: removing pid file /stunnel.pid 2005.03.31 14:06:06 LOG7[4552:0]: Steven: going into client_status with num_clients = 1 2005.03.31 14:06:06 LOG7[4552:0]: Process 4553 finished with code 0 (0 left) Now, netstat no longer shows the connections in any state. ---[ problem 2 Another problem that was found is that after bombarding stunnel with lots of connections, it stops accepting new connections. This would be normal if all connections remained open, but they are all closed. This is the error: Mar 31 13:53:40 hostname stunnel[13044]: Connection rejected: too many clients (>=4000) netstat only shows +- 500 connections, of which none are aimed at the stunnel process in question (port 4321 in my test setup) there is only 1 stunnel process active aswell. I dug into the problem a bit and it probably has to do with num_clients not being decreased after a process is closed (although I can not find any specifics :/) greets, -- Steven

Does stunnel work on Windows 2000 & SIMP(Secure Instant Messaging) ??

Hi Group, I have a windows 2000 box & want to communicate securely with someone else via SIMP(Secure Instant Messaging Protocol - http://www.winfosec.com/simp.php) I know that SIMP Instant Messaging is a "Direct Connection" & does NOT go through an intermediary server & that its encrypted, but being the security nut I am, I want to know if "stunnel" handles the SIMP protocols ? ... as I can't find anywhere what the SIMP protocols are ... because as I have read in the stunnel FAQ, stunnel does not handle UDP.

Hi Mike, Thank you for your precious help. I am using stunnel as SSL client. The SSL server runs in a router. As you suggested me, I have done these changes: at first I have modified the stunnel.conf with options = SSL_OP_TLS_BLOCK_PADDING_BUG stunnel.conf ============================== client = yes debug=7 options = SSL_OP_TLS_BLOCK_PADDING_BUG [telnet] accept = 23 connect = 10.36.3.144:4433 ============================= but I have got this error ======================================= file stunnel.conf line 5: Illegal SSL option 2005.03.31 13:26:48 LOG3[3396:3716]: Server is down ======================================= After I have changed the stunnel.conf in this way: stunnel.conf ============================== client = yes debug=7 ciphers = RC4-MD5 [telnet] accept = 23 connect = 10.36.3.144:4433 ============================== The problem I had is now solved. But my question is: how can I know more about this protocol incompatibility? Is there an accurate documentation about that and also about stunnel configuration? Sorry but sometimes it's difficult for me to find (in the FAQ or other sessions) the informations that I need. Thanks&Regards Maddalena

The IDEA algorithm is patented, but I don't think Mike included that in his builds. You can configure Stunnel to only use specific ciphers, in which case you wouldn't be using it regardless. Does that make it legal? Consult a lawyer. Software patents suck. I'd download the openssl.exe and the libs and run 'openssl.exe ciphers -v' and see exactly which ciphers it includes and avoid any from which your legal team suggess you run away. -- Brian Hatch If we aren't supposed Systems and to eat animals, why Security Engineer are they made of meat? http://www.ifokr.org/bri/ Every message PGP signed

New stunnel 4.09 can be found on my FTP site: ftp://stunnel.mirt.net/stunnel/ Here is the ChangeLog entry: * DLLs for OpenSSL 0.9.7f. * Bugfixes - Compilation problem with undeclarated socklen_t fixed. - TIMEOUTclose is not used when there is any data in the buffers. - Stunnel no longer relies on close_notify with SSL 2.0 connections, since SSL 2.0 protocol does not have any alerts defined. - Closing SSL socket when there is some data in SSL output buffer is detected and reported as an error. - Install/chmod race condition when installing default certificate fixed. - Stunnel no longer installs signal_handler on ignored signals. Best regards, Mike

error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number

I was running stunnel-4.08 under Windows XP-Home, using MS IEX as browser and Netscape 4.6 for e-mail. My ISP is AT&T Worldnet and I am accessing it via DSL and home wireless NW. Here is stunnel.conf: client = yes [pop3] accept = 110 connect = ipostoffice.att.net:995 [smtp] accept = 25 connect = imailhost.att.net:465 As instructed by AT&T, the e-mail servers have been specified as "localhost", both POP-3 and SMTP. The problem is that while I can download messages, I am unable to send e-mail because the "peer disconnects", and the log file carries the following messages: 2005.03.24 10:18:00 LOG5[2960:232]: smtp connected from 127.0.0.1:2194 2005.03.24 10:18:00 LOG5[2960:2428]: smtp connected from 127.0.0.1:2197 2005.03.24 10:18:01 LOG3[2960:232]: SSL_connect: Peer suddenly disconnected 2005.03.24 10:18:01 LOG3[2960:2428]: SSL_connect: Peer suddenly disconnected 2005.03.24 10:18:09 LOG3[2960:2084]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2005.03.24 10:18:09 LOG3[2960:3384]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number I have been able to run "openssl version" with the result: "OpenSSL 0.9.7e 25 Oct 2004" but I am unable to obtain the other outputs specified under the instructions for the "Stunnel-Users Mailing List". I have tried replacing libssl32.dll and libay32.dll with versions more recently downloaded (but with the same origination dates) and no improvement. So I am sending this message from another system running Win98 and stunnel-4.05, also using Netscape 4.6, which seems to work o.k. Please tell me how to get the right version number to work with stunnel-4.08, and WinXP. Additionally, it would be nice to know how to obtain the outputs suggested in the instructions for Stunnel-Users Mailing List.

Problems using STunnel with a non-default port - Please Help
by Chetan Rao 22 Mar '05

22 Mar '05

I have a personal webserver running on Win2K Pro SP4 that listens on port 17875. This server is accessible through my NAT and software firewall (ZoneAlarm Pro). I then installed STunnel with the following conf: [https] accept=4430 connect=17875 TIMEOUTclose=0 Now, when I access https://<server>:4430, I get a HTTP 400 (Bad Request) error message, with both Internet Explorer 6 and FireFox 1.01. However, if I change the accept port from 4430 to 443 (and make the appropriate changes on the NAT for port forwarding), and use https://<server>, it works. I don't want to use the standard port. What am I doing wrong? Here's the log that STunnel generated: 2005.03.16 08:33:26 LOG5[1044:288]: stunnel 4.08 on x86-pc-mingw32-gnu WIN32+IPv4 with OpenSSL 0.9.7e 25 Oct 2004 2005.03.16 08:33:26 LOG7[1044:1096]: RAND_status claims sufficient entropy for the PRNG 2005.03.16 08:33:26 LOG6[1044:1096]: PRNG seeded successfully 2005.03.16 08:33:26 LOG7[1044:1096]: Certificate: stunnel.pem 2005.03.16 08:33:26 LOG7[1044:1096]: Key file: stunnel.pem 2005.03.16 08:33:26 LOG5[1044:1096]: No limit detected for the number of clients 2005.03.16 08:33:26 LOG7[1044:1096]: FD 168 in non-blocking mode 2005.03.16 08:33:26 LOG7[1044:1096]: SO_REUSEADDR option set on accept socket 2005.03.16 08:33:26 LOG7[1044:1096]: https bound to 0.0.0.0:4430 2005.03.16 08:34:08 LOG7[1044:1096]: https accepted FD=180 from 192.168.0.2:4864 2005.03.16 08:34:08 LOG7[1044:1096]: FD 180 in non-blocking mode 2005.03.16 08:34:08 LOG7[1044:1096]: Creating a new thread 2005.03.16 08:34:08 LOG7[1044:1096]: New thread created 2005.03.16 08:34:08 LOG7[1044:896]: https started 2005.03.16 08:34:08 LOG5[1044:896]: https connected from 192.168.0.2:4864 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): before/accept initialization 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 read client hello A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write server hello A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write certificate A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write server done A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 flush data 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 read client key exchange A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 read finished A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write change cipher spec A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 write finished A 2005.03.16 08:34:08 LOG7[1044:896]: SSL state (accept): SSLv3 flush data 2005.03.16 08:34:08 LOG7[1044:896]: 1 items in the session cache 2005.03.16 08:34:08 LOG7[1044:896]: 0 client connects (SSL_connect()) 2005.03.16 08:34:08 LOG7[1044:896]: 0 client connects that finished 2005.03.16 08:34:08 LOG7[1044:896]: 0 client renegotiatations requested 2005.03.16 08:34:08 LOG7[1044:896]: 1 server connects (SSL_accept()) 2005.03.16 08:34:08 LOG7[1044:896]: 1 server connects that finished 2005.03.16 08:34:08 LOG7[1044:896]: 0 server renegotiatiations requested 2005.03.16 08:34:08 LOG7[1044:896]: 0 session cache hits 2005.03.16 08:34:08 LOG7[1044:896]: 1 session cache misses 2005.03.16 08:34:08 LOG7[1044:896]: 0 session cache timeouts 2005.03.16 08:34:08 LOG6[1044:896]: SSL accepted: new session negotiated 2005.03.16 08:34:08 LOG6[1044:896]: Negotiated ciphers: RC4-MD5 SSLv3 Kx=RSA Au=RSA Enc=RC4(128) Mac=MD5 2005.03.16 08:34:08 LOG7[1044:896]: FD 200 in non-blocking mode 2005.03.16 08:34:08 LOG7[1044:896]: https connecting 127.0.0.1:17875 2005.03.16 08:34:08 LOG7[1044:896]: connect_wait: waiting 10 seconds 2005.03.16 08:34:08 LOG7[1044:896]: connect_wait: connected 2005.03.16 08:34:08 LOG7[1044:896]: Remote FD=200 initialized 2005.03.16 08:34:08 LOG7[1044:896]: Socket closed on read 2005.03.16 08:34:08 LOG7[1044:896]: SSL write shutdown 2005.03.16 08:34:08 LOG7[1044:896]: SSL alert (write): warning: close notify 2005.03.16 08:34:08 LOG7[1044:896]: SSL_shutdown retrying 2005.03.16 08:34:08 LOG7[1044:896]: s_poll_wait timeout waiting for SSL close_notify 2005.03.16 08:34:08 LOG5[1044:896]: Connection closed: 208 bytes sent to SSL, 389 bytes sent to socket 2005.03.16 08:34:08 LOG7[1044:896]: https finished (0 left) Any help much appreciated.

Certificate chain not used for server?
by Ed Kapitein 21 Mar '05

21 Mar '05

Hi all, I have a working setup of stunnel listening on port 443 and connect to the server on the same host on port 80. It is done via xinetd. Alltough everything is working just fine, clients on webbrowsers get the "you have choosen not to trust this CA" error when connecting to this server. In apache the certificate chain (bundle.ca) is used and clients connecting to the apache server wont get this error. Is there a way to make stunnel behave like apache, so the clients don't have to manually install the CA certificates? (the certificate is a vallid certificate obtained from globaslsign.be) i do have the CAfile in my options file, but this does not help. All help is greatly appreciated! Kind regards, @

Creating a man in middle attack for legit purposes.
by Todd Troutman 16 Mar '05

16 Mar '05

So I don't normally start off on a list by immediately asking a question but I've got a weird one here that's a critical thing tonight, plus, this might just be entertaining! Problem : MacOS Panther has horrible performance problems with large https web apps. So I setup Stunnel to take port 80 and run it through the web app on 443. Provides http from an https server. On a MacOS client machine I set /etc/hosts to say that system.netsuite.com, the web app, is 192.168.0.4, a handy FreeBSD 5.3 box running stunnel 4.05 It works. Sort of. Problems - the web app keeps rewriting the url from http to https, anytime I click on anything, hmmm.. so I can't make stunnel answer on 443 because then I'm back to square one. Also, I can't login, the web app is giving me a login page as http, but I get a session timeout,please login again, just repeats, unsure if something in the stunnel config should be done to fix that. Other than that, this is working. Config is currently this. client=yes accept=80 connect=system.netsuite.com:443 Anyway, so is this maybe one of the stranger uses of stunnel, possibly a wrong headed and broken way of using it, but oh well. There goes my plea for some ideas on this one, Thanks, Todd

Radius over Stunnel??
by Frazer, Andrew non Unisys 08 Mar '05

08 Mar '05

Hello all.. I would like to pass radius over stunnel, but I'm not sure if this will work... I have a lot of 'client's that are using RADIUS for authentication, but i want to pass the data over the internet, and radius is relatively insecure. My client machines also run a web server, which stunnel sits in front of, to provide ssl encrypted web services. My radius servers can easily run stunnel, without any issue. Could someone suggest a configuration for this??

syslog question
by Brian T 04 Mar '05

04 Mar '05

If debug=4 ( or not 0 ) and output= is commented in an stunnel config, it looks like in server mode, messages goto syslog. But in client mode, nothing goes to syslog. Is this the way it's supposed to be? -Brian

Re: [stunnel-users] long delay to close the ssl session ?
by ikeda＠areabe 04 Mar '05

04 Mar '05

If TIMEOUTclose value is positive, stunnel does not transmit TCP FIN, even though application sends TCP FIN, until timeout time expires I don't know why stunnel designer chose it, maybe because of the performance, or some others. Some of the browsers do not start to display the page until receiving the entire packet. And one of the trigger for the browser to detect to receive the whole is TCP FIN. From that things, such kind of the problem of yours occurs. regards taka On Fri, 4 Mar 2005 10:39:47 -0800 (PST), gary ng <garyng2000(a)yahoo.com> wrote: > Thanks, that did the trick.

long delay to close the ssl session ?
by gary ng 04 Mar '05

04 Mar '05

Hi, I am using stunnel to wrap SSL around SWAT. Everything works fine except that it takes a very long delay for the browser to see that the page has already been transmitted completely(in other words, the other end has closed). I observed this behaviour with both 3.x and 4.x stunnel. Looking through the log, I see that it takes exactly one minute from the start of the session till the session is closed, seems to be some parameter within stunnel to hold the session. I tried both inetd as well as stand alone stunnel mode and both behave the same as well. Is this an issue with SWAT or stunnel ? If I just use plain SWAT through inetd, I don't see this behaviour. thanks for any help in advance. gary __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Anyone here managed to build stunnel for Irix? it seems socklen_t is undefined as a type on this OS (and also older versions of solaris). I have found a possible solution here: http://sprg.ssl.berkeley.edu/~fastops/ITOS/portable/socklen$_t.html but I need to know what type this identifier is supposed to be. any help?

Naive question: will stunnel connect dynamically?
by Duncan Murdoch 02 Mar '05

02 Mar '05

I currently use openssh to open a tunnel between my laptop and my POP3 server, but the tunnel keeps locking up. (I think it's a server problem, or an intermittent line problem, because it happens with both openssh and Putty.) What I'd like is a program that would open the tunnel only as needed, so I can get the mail, and let the tunnel close. Can stunnel do this? More generally, is there a quick summary somewhere on the relative benefits of stunnel's use of SSL versus an SSH approach? Duncan Murdoch

Windows XP Pro as a client of Remote Dekstop via stunnel
by Jacek Baszkiewicz 02 Mar '05

02 Mar '05

Hi! I'm currently working (without success) on such problem: I have to connect via Stunnel to Windows Server Remote Desktop from workstation with Windows XP Proffesional. When I refer to the local port handled by stunnel, Windows doesn't let me go go further, because it thinks that I'm trying to use local Remote Dekstop and prints: "You are already connected to this machine" (there can be only one connection through RD) . Is there any workaround for this problem, namely, to use secure connection via Stunnel to Remote Dekstop on XP Pro client? This is my config: client=yes cert = stunnel.pem [ts] accept=localhost:3389 connect=remote_ip:443

stunnel woes under HPUX 10.20
by foner-stunnel＠media.mit.edu 28 Feb '05

28 Feb '05

[Please keep me CC'ed on replies! I'm not on any stunnel lists.] Stunnel 4.07 and 4.08 don't build under HPUX 10.20. 4.06 appears to build, but doesn't appear to work---with a config file like this, running on the local host: pid = /usr/local/var/stunnel/stunnel.pid client = yes foreground = yes # debug = debug [pop3s] accept = 110 connect = our-pop-host:995 ...and an attempt like this, using (for instance) Emacs 21.4a's movemail: movemail po:foner:localhost NEWMAIL [the-password] ...I get an infinite hang. Enabling debugging causes stunnel to spit out an infinite stream of a single line at maximum rate, and seems unaffected by whether I'm trying to connect to it or not: # stunnel test-stunnel.conf 1900.01.00 00:00:00 LOG5[9738:0]: stunnel 4.06 on hppa1.1-hp-hpux10.20 FORK+POLL with OpenSSL 0.9.7e 25 Oct 2004 1900.01.00 00:00:00 LOG7[9738:0]: Snagged 64 random bytes from /users/foner/.rnd 1900.01.00 00:00:00 LOG7[9738:0]: Wrote 1024 new random bytes to /users/foner/.rnd 1900.01.00 00:00:00 LOG7[9738:0]: RAND_status claims sufficient entropy for the PRNG 1900.01.00 00:00:00 LOG6[9738:0]: PRNG seeded successfully 1900.01.00 00:00:00 LOG6[9738:0]: file ulimit = 60 (can be changed with 'ulimit -n') 1900.01.00 00:00:00 LOG6[9738:0]: poll() used - no FD_SETSIZE limit for file descriptors 1900.01.00 00:00:00 LOG5[9738:0]: 27 clients allowed 1900.01.00 00:00:00 LOG7[9738:0]: FD 3 in non-blocking mode 1900.01.00 00:00:00 LOG7[9738:0]: FD 4 in non-blocking mode 1900.01.00 00:00:00 LOG7[9738:0]: FD 5 in non-blocking mode 1900.01.00 00:00:00 LOG7[9738:0]: SO_REUSEADDR option set on accept socket 1900.01.00 00:00:00 LOG7[9738:0]: pop3s bound to 0.0.0.0:110 1900.01.00 00:00:00 LOG7[9738:0]: Created pid file /usr/local/var/stunnel/stunnel.pid 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) 1900.01.00 00:00:00 LOG6[9738:0]: daemon_loop: s_poll_wait: Invalid argument (22) [ . . . and forever more . . . ] I can't imagine that this is supposed to be how debug works, since it's totally useless for debugging if it spits out the same line as fast as it can. I'm running the stunnel as root, and netstat seems to show that it's bound to port 110, but doesn't seem to indicate any outbound connection from stunnel to our pop host after I invoke movemail. I have no idea if versions before 4.06 work; I haven't tried. Sure, this is an old OS, but zillions of other things, including the entire GNU toolchain, seem to work on it, so stunnel should, too. Builds for all three versions I've tried may be found in at the following URLs. Note that 4.07 and 4.08 fail on different files, but in essentially the same way. http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.06.build http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.07.build http://foner.www.media.mit.edu/people/foner/Sys/stunnel-4.08.build I've done some websearching, and I've searched the stunnel archives at mirt.net, but haven't found anything relevant. Any clues? Thanks...

stunnel logging problem
by Brian T 28 Feb '05

28 Feb '05

Hi, I work for a company which has a custom embedded Linux platform, and have been working with stunnel for some time but have never seen this problem. I have seen it with stunnel 4.04 and 4.07, which is compiled on a Redhat 7.2ish platform, but newer SSL libraries. (below my sig is the stunnel info). Basically I use a config file, but when debug= and output= is commented out, stunnel seems to cause a problem which resets the embedded unit. If I uncomment them both and use output=/var/log/stunnel.log ( or /dev/null ) everything works fine. Not sure where to look for the problem that is causing this since I can't even get a core dump. I looged in s_log() but nothing stuck out as being wrong. Thanks for any help you can lend, -Brian [root@JBMgateway-v63 /]# stunnel -version stunnel 4.07 on i486-pc-linux-gnu PTHREAD+POLL+IPv4+LIBWRAP with OpenSSL 0.9.7d 17 Mar 2004 Global options cert = /etc/stunnel/stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = /etc/stunnel/stunnel.pem pid = /var/run/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes session = 300 seconds verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds [root@JBMgateway-v63 /]# uname -a Linux JBMgateway-v63 2.4.20 #1729 Wed Jan 26 17:38:15 CST 2005 i486 unknown [root@JBMgateway-v63 /]# ls -al /lib/libssl.so.* -rwxr-xr-x 1 root root 210452 Jan 26 18:47 /lib/libssl.so.0.9.7 lrwxrwxrwx 1 root root 20 Jan 26 18:47 /lib/libssl.so.2 -> /lib/libssl.so.0.9.7 [root@JBMgateway-v63 /]# cat /etc/stunnel/stunnel.conf # Some debugging stuff debug = 6 output = /var/log/stunnel.log #output = /dev/null foreground = yes # Use it for client mode client = yes [SampleGroup] accept = 443 connect = x.x.x.x:6660

openssl - generating stunnel.pem - stunnel.cnf
by k-i-r＠web.de 24 Feb '05

24 Feb '05

Using Stunnel under Windows I want to create a certificate (stunnel.pem) with Openssl. According to FAQ the syntax for creating a certificate with Openssl is openssl req -new -x509 -days 365 -nodes -config stunnel.cnf -out stunnel.pem -keyout stunnel.pem I use openssl for windows (as part of apache-windows-http-server) . Where do I get the file stunnel.cnf ? Or is this file not necessary for creating a certificate ? Thanks for help, k.

Stunnel and configuration
by Bohdan Linda 22 Feb '05

22 Feb '05

Hi all, I have configured stunnel to do the client authetication, but I have some question. I have used following config: cert = /etc/certificates/server.pem - file with signed server cert and key (passwordless) chroot = /var/run/stunnel/ CAfile = /etc/certificates/certs -file where first item is my CA certificate followed by list of all client certificates sgined by my CA. setuid = nobody setgid = nogroup pid = /stunnel.pid verify = 3 This setup is working, but this seems to me very "unlogical". If I create for me "more logic" setup: cert = /etc/certificates/server.pem chroot = /var/run/stunnel/ CAfile = /etc/certificates/CA/cacert.pem - only certificate of my CA CRLfile = /etc/certificates/crls - only certificates signed by my CA I get the following error: 2005.02.22 15:15:10 LOG5[22418:81926]: VERIFY OK: depth=1, /C= ..... 2005.02.22 15:15:10 LOG4[22418:81926]: VERIFY ERROR ONLY MY: no cert for /C= The question is ... why? Why CAfile has to contain all client certificates, when clients certs are not CA? Why I cannot have separate file for CA and separate file for certificates that I want accept? If I do the similar setup in mod_ssl, the configuration works as expected. Anyway, I'am newbie to deploy stunnel, thus I would like to ask you for giving me you opinion of this configuration, caveats and possible enhancements. Thanks for any comments, Bohdan Linda

multiple stunnel client
by Manila, Dinesh - Contractor 15 Feb '05

15 Feb '05

Hi, I am working in a project, whereas the EMS application need to be secured while communicating with NE. To make it secure, we have decided to go with stunnel and openSSL. I have following questions while using stunnel in my application: 1. I read that stunnel limits the number of clients to be connected to 125. Can I increase this number. If so, by increasing this number, what is the implication in performance of stuunel. 2. Since my EMS is capable of managing more than 1000 NEs, I would want to have multiple stunnel client running on the same workstation. Is this possible to have multiple stuunel process running on the same server. if so, how should my stunnle.conf file look like. I appreciate greatly, If I could get the answers for the above queries. Thanks and Regards, Dinesh Wipro Technologies. Bangalore.

Multiple listeners with just one instance of Stunnel?
by Michael Zarlenga 15 Feb '05

15 Feb '05

It doesn't seem possible to start 1 instance of Stunnel for multiple accept ports. Judging by the format of the Stunnel configuration file, it seems that I need to 1 instance of Stunnel for each port that accepts connections from the outside world. Is this true?

using no certificate
by Zohar 14 Feb '05

14 Feb '05

Hi, I'm very new to all this issue of SSL, so I apologize if this question sounds stupid. I currently have a server that listens to connections on a TCP port. Clients that connect to it may do so using SSL v3 (mobile clients, which use their own SSL packages, so I have very little control over it). I want to add stunnel to my server's setting, to enable SSL communication. I have no need for the client to authenticate the server, I am only interested in the data being encrypted. I tried setting this up, but the client complains that my server certificate cannot be authenticated (I produced it using http://www.stunnel.org/pem/). Any pointers on how to set such a thing up (even for the time being, while I develop), without having to pay lots of money to a CA ?

Multiple Instances of stunnel
by dps_maillists＠mac.com 11 Feb '05

11 Feb '05

Hi everyone; Is it possible to run multiple instances of stunnel (v 4.07) in client mode on a single machine? We sould like to use stunnel to secure connections from a small number of client applications (1 to 10) connecting to a larger number of server applications (200 per client app). Ideally, we would like to use one instance of stunnel per client. Many thanks in advance. Doug

hi, I've recently set up stunnel for SSL connect. When I test its performance with siege with 700 concurrency request, I got this log: "Error: socket: connection timed out.: Operation now in progress" So, may I ask what is the upper limit of concurrency in stunnel, if the performance of the machine is good enough. and how can I increase the concurrency upper limit. thanks

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Since I want to write CRL files from all relevant CAs based on a regular (daily) basis I wonder whether it is necessary to restart stunnel if the contents of the CRL or CA directory changes.

Stunnel 4.05/4.07 Crash

28 Jan '05

Hi, I've initiated 11 stunnel processes in the same server. Each of the stunnel process has its own client certificate to communicate to application server. However after sometime of execution, the stunnel processes are crached (dying off) one by one. below is the last portion of my log (with debug level 7). I don't see any critical error in the log. Would appreciate if someone could highlight to me what cause the problem or anyone has similar experience. 2005.01.25 16:02:41 LOG7[2244:1424]: 0 server connects that finished 2005.01.25 16:02:41

Profiling STunnel

All, I need to do some performance profiling on STunnel. I assume gcov and gprof are the correct tools for this. Does anyone have any experience profiling STunnel? Any advice on how to do it properly would be appreciated. Thanks Mark Swann

Cannot find License.CM file
by Ranjit Mallick 26 Jan '05

26 Jan '05

Hi , I am new to stunnel , one of the previous develoeper has developed a application using Stunnel, essentially this app will work as a proxy to outside world and tunnel back to the remote server. On the server side the Stunnel has License.cm file and when ever I bring stunnel in CMD mode, it shows a message cannot find the License.cm file(even though it is there), Obviously the License file has expired or corrupted. How do I tell this tunnel.exe not to look for that file or how can I generate a license file(.cm)? Pls note that the tunnel has all the required files in it's directory tunnel.pem,tunnel.conf,ssleay32.dll,libeay32.dll,ssleay32.exp), pls help this is a show stopper and is effecting the client.Any leads or direction will be much appreciated. Thank you Ranjit __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

win32 stunnel - quiet service install
by joe smith 22 Jan '05

22 Jan '05

I would like to request the following feature be included in subsequent releases of stunnel. Cheers, Jeff Greetings, It would be great if while installing as a service on win32, there was an option to install quietly - i.e. only pop up a dialog box to the user if there's a problem. Any chance of somebody nice compiling me a binary that does this? :) M. -- Michael Brown {0x527670C0} | `One of the main causes of the fall of Systems Administrator | the Roman Empire was that, lacking zero, +1 519 888 7111 x2339 | they had no way to indicate successful michaelb at opentext.com | termination of their C programs.' - Firth --------------------------------- Do you Yahoo!?

stunnel and verify
by Brian Hirt 21 Jan '05

21 Jan '05

Hi, I've recently set up stunnel for a remote vnc connection, and it's working great. However, I would like to restrict access based on cert (only allow access a single public key), because nobody else should be accessing it besides my one machine. It seems what i want is to set verify = 3, but I'm using self-signed certs on my client, so verify = 3 fails. Is there some way to verify the client public key without doing the self signed test too? I'm sorry if this is a faq -- i searched the lists and read the faq and couldn't find anything. Thanks! (I'm running stunnel 4.04 on fedora1, and stunnel 4.04 on mac 10.3.7, installed via fink) my stunnel.conf is pretty simple. client conf is (sans connection info) client = yes cert = /sw/etc/stunnel/stunnel.pem chroot = /var/run/stunnel/ pid = /stunnel.pid setuid = stunnel setgid = stunnel server conf is: client = no cert = /etc/stunnel/stunnel.pem CApath = /etc/stunnel/clientdb chroot = /var/run/stunnel/ verify=3 pid = /stunnel.pid setuid = stunnel setgid = stunnel -------------------------------------------- MobyGames http://www.mobygames.com The world's largest and most comprehensive gaming database project

As it is already present in the services list, this has to fail. You can easily start and stop stunnel using the net command from a command line window: net start stunnel to start stunnel, or: net stop stunnel to shut it down again. You could make up a batch file to launch stunnel automatically for the time agent is running: --file runagent.cmd begin-- @echo off net stunnel start C:\Program Files\Agent!\Agent32.exe net stunnel stop --file runagent.cmd end-- Just edit the path for agent32.exe to match the path where you have Forté Agent installed, and you're done. P.S. I know net stunnel start can complain about that the service is already running, but that's just cosmetical and I was too lazy to implement logic to check if the service is already running ;) Best regards, Andre

Activating Stunnel After Exiting (Newbie)
by mhrtmhd94＠att.net 20 Jan '05

20 Jan '05

Hi. I just installed Stunnel, in order to be able to continue Agent as my mews reader. This works well. Based on the cautions on the website, I have decided to keep Stunnel active only when I am using Agent. Stunnel opens when I boot Windows - (XP Home Edition with Service Pack 2.) After close Agent, I right-click the Stunnel icon on the task bar and choose Exit. If I try to activate Stunnel later, by double-clicking its desktop icon, I am presented with an error window headed "stunnel 4.07 on Win32" with the following message: "Failed to create a new service". Looking at Properties on the desktop, I see that the Target is "C:\stunnel\stunnel-4.07.exe -install". This looks wrong, as it appears to be the option for initial installation of the program. I assume I need to change this, or discover another method of re-opening stunnel. As it stands now, I have to reboot to accomplish this. Any assistance will be appreciated. Thanks.

stunnel dropping connection with media wiki
by christopher＠baus.net 12 Jan '05

12 Jan '05

Hi all, I've been using stunnel with SMTP, IMAP, and HTTP with out a problem. Yesterday I installed media wiki on Fedora Core 2 w/ Apache. It works fine if I access it directly, but if I access the site via stunnel, the proxy drops connection. I was wondering if anybody else has seen this type of problem. I am tempted to dig into it, but I am honestly short on time right now. I think it might have something to do with the redirects that Media wiki uses, but that's just a wild guess.

Stunnel and DistCache Patch
by Kling, Kent M. 10 Jan '05

10 Jan '05

we have a RedHat 7.2 system and we are trying to apply the distcache_geoff.patch to enable distcache 1.4.5 with stunnel-4.04. We have run into a snag after the configure script is run and we attempt the "make", it complains that configure.in is missing. In step 2 is our "configure" line wrong? # make output: cd . && aclocal cd . && automake --gnu --include-deps Makefile cd . \ && CONFIG_FILES=Makefile CONFIG_HEADERS= /bin/sh ./config.status config.status: creating Makefile cd . && autoconf autoconf: configure.in: No such file or directory make: *** [configure] Error 1 Our work around is to change directory into the /usr/src/stunnel-4.04/src and run "make" from that directory to create our stunnel binary. Any idea why it won't work from the top directory. our stunnel source resides in /usr/src/stunnel-4.04, distcache_geoff.patch is in /usr/src and distcache-1.4.5 is in /usr/local/distcache-1.4.5.

Newbie trying to connect over a Microsoft Proxy
by Michael Blake 05 Jan '05

05 Jan '05

Hi All I'm a relative newbie to Stunnel, and am trying to set up a tunnel so I can Remote Desktop from work to my PC/server at home. I'm using versions 4.05 & 4.06 of the Windows binaries. A Microsoft Proxy Server v2.0 is used at work, and it proxies HTTP, Secure (is that SSL/port 443??), FTP and Gopher over port 800. I'm not sure if it proxies Socks, as there's no entry for it in Internet Explorer. I've tested the configuration and it works on my LAN, and it works from home when I enter my domain home (so my firewall is set up correctly). My config is as follows: #Client CAfile = stunnel.pem cert = stunnel.pem client = yes verify = 3 [rdp-80] accept = localhost:3390 connect = xxx.xxx.xxx.xxx:80 #Server CAfile = stunnel.pem cert = stunnel.pem client = yes verify = 3 [rdp-80] accept = 192.168.10.221:80 connect = 127.0.0.1:3389 Is there something I need to do to traverse this proxy? Any help would be greatly appreciated! Tks, Michael Blake IT Consultant | Headbyte Limited Tel: + 44 7909 844273 http://www.headbyte.co.uk

stunnel-4.07 on non-IPv6 systems
by Hans Werner Strube 04 Jan '05

04 Jan '05

On systems which do not yet support IPv6 and do not have getnameinfo (for instance, Solaris 7), also NI_NUMERICHOST and NI_NUMERICSERV are usually undefined. In stunnel-4.07, this causes compilation of src/network.c to fail. Patch: *** src/network.c.ORI Mon Jan 3 00:20:27 2005 --- src/network.c Tue Jan 4 14:46:10 2005 *************** *** 73,78 **** --- 73,84 ---- static const char *s_gai_strerror(int); #ifndef HAVE_GETNAMEINFO + #ifndef NI_NUMERICHOST + #define NI_NUMERICHOST 2 + #endif + #ifndef NI_NUMERICSERV + #define NI_NUMERICSERV 8 + #endif static int getnameinfo(const struct sockaddr *, socklen_t, char *, int , char *, int , int ); #endif

Port forwarding based on application type
by Konda Ankireddyapalli 03 Jan '05

03 Jan '05

Hello all, Can stunnel forward the traffic to different ports based on an application type as opposed to by port? If yes, how can it be configured? My need is that on the client side we have many applications that share a single outgoing port. On the server side I want to demultiplex the stunnel traffic coming in on a single port to multiple applications after decryption. Thanks in advance, Konda

A couple of patches against 4.06
by Peter Pentchev 31 Dec '04

31 Dec '04

Hi, First of all, thanks for writing and maintaining this great piece of software :) When I ported 4.06 to FreeBSD on Monday, there were three changes that needed to be made. One is the passing of -1, not -1000, to poll(2), which has already been discussed on this list (and which, by the way, is mandated by POSIX and the Single Unix Specification, as you can see at http://www.opengroup.org/onlinepubs/007908799/xsh/poll.html ) The other two can be seen in the patch below. The first one is related to the fact that EAI_NODATA is not present on all systems - it was actually obsoleted by the KAME implementation of IPv6 about an year ago. On some systems it is defined and has its own value - then stunnel builds just fine. On other systems it is not defined at all, while on yet other systems it is aliased to EAI_NONAME, so 'case EAI_NONAME' and 'case EAI_NODATA' would produce an error message from the compiler. Thus, the #ifdef and #if in the first chunk of the patch. This could not be done portably with a single statement, something like '#if defined(EAI_NODATA) && EAI_NODATA != EAI_NONAME', since there are some compilers that would barf on the second part if EAI_NODATA was not actually defined. The second chunk of the patch fixes getnameinfo() error reporting - just like with getaddrinfo(), getnameinfo() errors should be displayed using s_gai_strerror() instead of sockerror(). Keep up the good work!

using stunnel for smb networking
by David Bear 28 Dec '04

28 Dec '04

out of curiousity, has anyone been able to use stunnel as a cheap vpn for smb/cifs windows networks? We have a stupid firewall policy that blocks ALL port 139 traffic. Yes, thats good most of the time since microsoft rpc's are notoriously insecure. It does cause a problem when we have other units at other universities with different firewall policies however, so I was hoping to go around the different bureacracies and tunnel it myself. just curious. -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"

I'm using Win2k SP4 fully patched. Help? :)

Stunnel 4.06 released
by Michal Trojnara 25 Dec '04

25 Dec '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Here is the ChangeLog entry: Version 4.06, 2004.12.26, urgency: LOW: * New feature sponsored by SURFnet http://www.surfnet.nl/ - IPv6 support (to be enabled with ./configure --enable-ipv6). * New features - poll() support - no more FD_SETSIZE limit! - Multiple connect=host:port options are allowed in a single service section. Remote hosts are connected using round-robin algorithm. This feature is not compatible with delayed resolver. - New 'compression' option to enable compression. To use zlib algorithm you have to enable it when building OpenSSL library. - New 'engine' option to select a hardware engine. - New 'TIMEOUTconnect' option with 10 seconds default added. - stunnel3 perl script to emulate version 3.x command line options. - French manual updated by Bernard Choppy <choppy AT free POINT fr>. - A watchdog to detect transfer() infinite loops added. - Configuration file comment character changed from '#' to ';'. '#' will still be recognized to keep compatibility. - MT-safe getaddrinfo() and getnameinfo() are used where available to get better performance on resolver calls. - Automake upgraded from 1.4-p4 to 1.7.9. * Bugfixes - log() changed to s_log() to avoid conflicts on some systems. - Common CRIT_INET critical section introduced instead of separate CRIT_NTOA and CRIT_RESOLVER to avoid potential problems with libwrap (TCP Wrappers) library. - CreateThread() finally replaced with _beginthread() on Win32. - make install creates $(localstatedir)/stunnel. $(localstatedir)/stunnel/dev/zero is also created on Solaris. - Race condition with client session cache fixed. - Other minor bugfixes. * Release notes - Win32 port requires Winsock2 to work. Some Win95 systems may need a free update from Microsoft. http://www.microsoft.com/windows95/downloads/ - Default is *not* to use IPv6 '::' for accept and '::1' for connect. For example to accept pop3s on IPv6 you could use: 'accept = :::995'. I hope the new syntax is clear enough.

Fwd: [stunnel-users] stunnel 'options' section of config file
by Justin Miller 21 Dec '04

21 Dec '04

I understand the security concerns... I was just trying different protocols because I was receiving weird error messages with some https proxies (using the mathias wald patch) about wrong version numbers, etc. Googling it seemed to indicate that enabling/disabling ssl2/ssl3/tls1 could do the trick. However, I can't even get 'openssl s_client...' to yield a successful connection with some of these proxies. Can stunnel handle incoming http or socks proxy requests/connections? If not, will you ever support that? For instance I want stunnel listening on a local port 8080 and connect to a remote https proxy, and I set the HTTP proxy server in gaim to localhost:8080. -Justin On Tue, 21 Dec 2004 15:20:19 +0100, Michal Trojnara <Michal.Trojnara(a)mobi-com.net> wrote: > Justin Miller wrote: > > So all looks well ang good...

stunnel 'options' section of config file
by Justin Miller 21 Dec '04

21 Dec '04

Is it just me, or does stunnel not seem to obey the ssl 'options' setting in the config file? I have the lines: options = TLS_ROLLBACK_BUG options = NO_TLSv1 options = NO_SSLv3 And when I start stunnel, the output is: 2004.12.20 07:47:46 LOG7[9981:1024]: Configuration SSL options: 0x06800000 2004.12.20 07:47:46 LOG7[9981:1024]: SSL options set: 0x06800000 So all looks well ang good... But then when it sends the client hello message, one would expect an ssl2 message, but we get the following output: 2004.12.20 07:47:51 LOG7[9984:1026]: SSL state (connect): SSLv3 write client hello A 2004.12.20 07:47:51 LOG7[9984:1026]: waitforsocket: FD=10, DIR=read 2004.12.20 07:47:51 LOG7[9984:1026]: waitforsocket: ok 2004.12.20 07:47:51 LOG7[9984:1026]: SSL alert (write): fatal: handshake failure 2004.12.20 07:47:51 LOG3[9984:1026]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number That first line seems to indicate that it's still sending a v3 message. Is this actually what's happening?

stunnel 4.06 and compression

Hello. Is there any way to get the beta version of stunnel 4.06 (I've seen in this list that it must support compression)? Or if I can't get new version - can I somehow enable compression in stunnel 4.05? Oleg Ivanov

Problem with huge stunnel.conf
by CIM Massy 20 Dec '04

20 Dec '04

Hi everyone ! I have 900 (W2K) machines that I have to securely log onto. I chose to use both of Ultr@VNC and RealVNC 4.0 (running on ports 5900 & 5901). And I chose to use STunnel 4.05 on W2K to secure the sockets. On my admin PC, Stunnel.conf looks like /*******************************/ #cert stuff [ultravnc0101] accept = 127.0.1.1:5900 connect = PC0101:5700 [realvnc0101] accept = 127.0.1.1:5901 connect = PC0101:5701 ... [ultravnc1000] accept = 127.0.10.0:5900 connect = PC1000:5700 [realvnc1000] accept = 127.0.10.0:5901 connect = PC1000:5701 /*******************************/ And it does only work for the first 31 pairs of "services". (No Authentification issues.) When I move the "PC0101" services to the end of the file it will not work anymore, whereas it does when it's first in the .conf file. I guess having 1800 services is not necessarily the way Stunnel is meant to work... Is it a known issue ? I haven't been able to find any infos on it in newsgroups or with Google. It does not seem to be a W2K problem since it works with the 64 first services. If anyone knows a workaround... Thanks for your help, Reagrds Philippe HAMEAU

UDP applications
by Paul 20 Dec '04

20 Dec '04

Hi all, Is there any roadmap for Stunnel to support UDP applications? Cant a simple UDP forwarder (with proper buffering to ensure a tcp-like stream of data) do the job? May be this topic is discussed and brainstormed before. I couldnot find any relevant details about this in the archives. Thanks and Regards, Paul

Need help: verification of client and server certificates
by Mike_Stunnel 20 Dec '04

20 Dec '04

For my Stunnel server, I'm using Windows ME, OpenSSL 0.9.7e and Stunnel 4.05. I've create my own Certificate Authority on my server and created and signed a server and multiple client certificates for Stunnel. I plan to use Stunnel to secure my VNC connections to my PC - to encrypt the traffic and to validate the clients. On the server side: ------------------- I want to limit connections to my Stunnel server to only those Stunnel clients that present a client certificate that I already have a copy of on my server. And I want Stunnel server to only recognize my own Certificate Authority as a valid CA for the clients' certificates. Is this possible? What options do I need to specify in the Stunnel server configuration file to make this work? The documentation is confusing to me - for example, do I use CAfile or CApath to point Stunnel to the the CA certificate? Will Stunnel recognize other CAs as trusted, if their certificates have been loaded by other programs like a browsers or mail reader? Etcetera .. On the client side: ------------------- As with the server, I want my Stunnel client to only recognize my own CA as trusted. And I want it to validate the server certificate as thoroughly as possible. Is that verify level 3? I need the CA certificate on my client, but do I use CAfile or CAcert in the config file to point to it? Do I need a copy of the server certificate on my client so that the client can verify the server's certificate? I'm so confused! I've read the FAQ and Related links on stunnel.org and also the past 4 months' mailing list digests but I'm still not clear on the certificate verification process. or all the options in the configuration file.

I have been working/using stunnel for quite sometime... I am using it along with SOcks. So was wondering is there anyone who is already working on providing socks (v4 or v5) support to existing stunnel? Also is there any1 else who is also requires socks functionality in stunnel? Thanks and Regards, Paul.

same questions about problems with stunnel-4.05 and the old 3.2x command line
by 86493293＠gmx.net 02 Dec '04

Hi Michal, i'm using stunnel since version 3.2x and now i'm trying to switch to version 4.05. but there still some problems left so i searched the "net" and found only one article about this problems (http://stunnel.mirt.net/pipermail/stunnel-users/2004-August/000013.html). but this solution seems not to work for me or i'm a little bit to stupid to understand it. i used 3.2x with the following command line: $ stunnel -P ~/ -v2 -A ./publickey.pem -p privatekey.pem -r target_host.net:666 -c -d 127.0.0.1:7777 Then i tried to write me my own config-file for stunnel-4.05. $ cat /etc/stunnel/stunnel.conf # pid is created in an jail pid = /home/user/.stunnel/stunnel.pid # Some debugging stuff debug = 7 output = /home/user/.stunnel/stunnel.log # use it for client mode client = yes foreground = yes # Authentification verify = 3 cert = /home/user/privatekey.pem CAfile = /home/user/publickey.pem # Service-Level Configuration [application] accept = 127.0.0.1:666 connect = targethost.net:7777 But this one does not work. The stunnel.log told me this: $ cat /home/user/stunnel.log 2004.12.01 22:20:12 LOG5[15233:1006686208]: stunnel 4.05 on i386-unknown-openbsd3.6 PTHREAD+LIBWRAP with OpenSSL 0.9.7d 17 Mar 2004 2004.12.01 22:20:12 LOG7[15233:1006686208]: Snagged 64 random bytes from /dev/arandom 2004.12.01 22:20:12 LOG7[15233:1006686208]: RAND_status claims sufficient entropy for the PRNG 2004.12.01 22:20:12 LOG6[15233:1006686208]: PRNG seeded successfully 2004.12.01 22:20:12 LOG7[15233:1006686208]: Certificate: /home/privatekey.pem 2004.12.01 22:20:12 LOG7[15233:1006686208]: Key file: /home/user/privatekey.pem 2004.12.01 22:20:12 LOG7[15233:1006686208]: Loaded verify certificates from /home/user/publickey.pem 2004.12.01 22:20:12 LOG5[15233:1006686208]: FD_SETSIZE=1024, file ulimit=128 -> 61 clients allowed 2004.12.01 22:20:12 LOG7[15233:1006686208]: FD 7 in non-blocking mode 2004.12.01 22:20:12 LOG7[15233:1006686208]: SO_REUSEADDR option set on accept socket 2004.12.01 22:20:12 LOG7[15233:1006686208]: application bound to 127.0.0.1:666 2004.12.01 22:20:12 LOG7[15233:1006686208]: FD 8 in non-blocking mode 2004.12.01 22:20:12 LOG7[15233:1006686208]: FD 9 in non-blocking mode 2004.12.01 22:20:12 LOG7[15233:1006686208]: Created pid file /var/run/stunnel.pid It looks for me normal but i can not connect to this local port and i can not seen the "stunnel" as an process in my "ps -al |grep stunnel".

How use certificates with stunnel -- Newbie question
by Shatadal 25 Nov '04

25 Nov '04

Hi, I am a new user of stunnel and I am using it to connect to some SSL enabled e-mail accounts. Instead of directly connecting to the mail server I am connecting to it via stunnel so that my e-mail scanner scan the messages before sending it to the mail server (it does not natively support SSL connections) My setup: OS: Win XP Home edition. All updates are installed except for service pack 2. E-mail client: Mozilla Thunderbird 0.9 E-mail scanner : Alwil Avast 4.5 I have an e-mail account at myisp.com. To connect to myisp I need to enable SSL. On connecting via SSL I get a certificate which I can choose to accept permanently, temporarily for the current session or reject it. Alwil Avast mail scanner does not support scanning of e-mail sent and received over SSL. So to enable it to scan such e-mail, my client connects to localhost where stunnel is listening and stunnel forwards the connection to my isp. This is my stunnel.conf file # IMAP service, listens on localhost:1200 [myisp-imaps] accept=localhost:1200 connect=myisp.com:993 # SMTP service, listens on localhost:260 [myisp-smtps] accept=localhost:260 connect=myisp.com:25 Unfortunately while the IMAP connection works perfectly the SMTP does not. Thunderbird keeps sending the message until I cancel it. This is the log file 2004.11.25 03:10:03 LOG5[2508:3848]: myisp-smtps connected from 127.0.0.1:2751 2004.11.25 03:10:08 LOG3[2508:3848]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2004.11.25 03:11:03 LOG5[2508:192]: myisp-smtps connected from 127.0.0.1:2755 2004.11.25 03:11:08 LOG3[2508:192]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2004.11.25 13:36:40 LOG5[2508:2112]: myisp-smtps connected from 127.0.0.1:4818 2004.11.25 13:36:45 LOG3[2508:2112]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2004.11.25 14:01:44 LOG5[2508:3208]: myisp-smtps connected from 127.0.0.1:1188 2004.11.25 14:01:50 LOG3[2508:3208]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number I am guessing the problem is something to do with the handling of the certificate I get when I use my client to connect directly to the SMTP server via SSL. Can someone explain to me how to make stunnel accept the certificate and continue the SSL transaction? I tried to read through the faq for certificates but I couldn't understand how it was to be done. Thanks, Shatadal. --- avast! Antivirus: Outbound message clean.

Sercure POP from Outlook Express using Stunnel on a linux server to talk to an exchance server.
by CONN, Aurelia 25 Nov '04

25 Nov '04

Hi I'm just about to investigate setting up a secure pop connection to an exchange server - can anyone point to helpfull resources or say if it can/cannot be done. Using Outlook (Express) as mail client SSL and Stunnel installed on Redhat 9 Mailserver is Exchange 5.5 on Windows NT 4.0 For example, will I have to configure/install on all three boxes? All my initial testing will be done internally so no firewall issues at this stage. Thanks in advance.

SSL Engine patch on Windows?
by Kartik Subbarao 22 Nov '04

22 Nov '04

I'm trying to use stunnel with the SSL Hardware Engine patch (posted by Neil Dunbar to this mailing list in March) on Windows. I apply the patch to the 4.05 codebase and build stunnel with MinGW. I'm able to use stunnel normally without exercising any hardware engine functionality. This tells me that the basics are working. I then run stunnel with the config file containing the following kinds of hardware engine parameters: SSLEngine=c:\windows\system32\engine_pkcs11.dll SSLEngineOpt=MODULE_PATH=c:\windows\system32\acpkcs201.dll But when I run stunnel, I get errors with dynamic library loading like: error stack: 260B6084 : error:260B6084:engine routines:DYNAMIC_LOAD:dso not found And similar errors like that. This gives me the impression that I haven't linked stunnel properly on windows to be able to use OpenSSL dynamic libraries. Or perhaps some other explanation that I don't understand :-) Is it possible to compile stunnel on Windows (either with MinGW or with Visual C++) to be able to use the hardware engine patch? Any pointers/assistance would be greatly appreciated. Thanks, -Kartik

List of Distinguished names in Certificate Request message
by Diarmuid O'Neill 17 Nov '04

17 Nov '04

Hi, At the moment, stunnel's client certificate verification implementation does not include any Distinguished Names (of the trusted CA certificates configured) in the Request Certificate message. Strictly speaking this violates RFC2246 (see below, apologies for formatting), but to date I've only seen one client that has a problem with it. Explorer deals with this by displaying all available user certificates. If the Distinguished Names are included in the cert req it only displays client certs signed by the appropriate CAs. The patch below does the necessary openssl bits and pieces to make up the lists of DNs so they're sent with the certificate requests. This has been tested under linux only. 7.4.4. Certificate request When this message will be sent: A non-anonymous server can optionally request a certificate from the client, if appropriate for the selected cipher suite. This message, if sent, will immediately follow the Server Key Exchange message (if it is sent; otherwise, the Server Certificate message). Structure of this message: enum { rsa_sign(1), dss_sign(2), rsa_fixed_dh(3), dss_fixed_dh(4), (255) } ClientCertificateType; opaque DistinguishedName<1..2^16-1>; struct { ClientCertificateType certificate_types<1..2^8-1>; DistinguishedName certificate_authorities<3..2^16-1>; } CertificateRequest; certificate_types This field is a list of the types of certificates requested, sorted in order of the server's preference. certificate_authorities A list of the distinguished names of acceptable certificate authorities. These distinguished names may specify a desired distinguished name for a root CA or for a subordinate CA; thus, this message can be used both to describe known roots and a desired authorization space. Note: DistinguishedName is derived from [X509]. Note: It is a fatal handshake_failure alert for an anonymous server to request client identification.
