Indirect CRL Support
by Sligar, Benjamin 21 Oct '11

21 Oct '11

I have been working, over the past few weeks, with one of my developers, attempting to support Indirect CRL's through OpenSSL/Stunnel. My initial attempts were to support direct CRL, which seems to work fine with the compile options I've listed below for both OpenSSL and Stunnel. ./config --prefix=/u/publish/dev/openssl/openssl-1.0.0d no-idea no-mdc2 no-rc5 no-md2 no-sse2 ./configure --prefix=/usr/local/stunnel-4.44/ --with-ssl=/usr/local/openssl-1.0.0d/ Reading through the FAQ and general documentation, I'm not finding much useful information on how to enable iCRL support. It may be a simple compile option I'm missing, or perhaps I just didn't find the correct page on the site/documentation, yet. If anyone has any useful information, or can point me in the right direction, the help would be greatly appreciated. I can provide configuration files and logs if it's of any use in this. Thank you in advance for any help you may be able to provide!

NETBIOS over stunnel
by Ronald RiemVis 18 Oct '11

18 Oct '11

Dear all, Stunnel work with all kind of other connections on both side but can't get working the NETBIOS negotiation with the net use command. send like: net use q: \\10.0.0.1\name password /user:username does not work when use net use q: \\10.0.0.1\name /user:username I get the question about password.At the end also will fail Because an ISP blocked all traffic over port 139 and my friend want to attach my external LAN drive (my book live) I need to redirect ports including the netbios protocol. I want: from a local loopback network adapter with IP address 10.0.0.1 port 139 to an external adddres port 1000 This is the configuration on the site where the my book live is connected: client = yes [MyBook] accept = 10.56.10.100:1000 (is my local address) connect = 10.56.10.10:139 (address of the my book live device) On the other side is the coinfiguration: client = yes [MyBook] accept = 10.0.0.1:139 (loopback addapter address) connect = remote address:1000 (external address) What can I do more to let it work? Greetings, Ronald

default ciphers in stunnel 4.43 vs. stunnel 4.33
by Brian Peterson 14 Oct '11

14 Oct '11

Hello, I recently upgraded stunnel from 4.33 to 4.43 and immediately noticed problems with a particular client trying to connect to my servers. It appears that the client only supports SSLv2 (about which I will be talking to the client developers). In reviewing the stunnel release notes, I find that "!SSLv2" was first added to the default ciphers value in 4.37 and was retained in the default ciphers value in 4.40. What I am trying to find out at this point is what the default cipher list would have been under 4.33. I have grep'd the sources and found STUNNEL_CIPHER_LIST in options.c for 4.43, but there is no corresponding default ciphers config in 4.33. It *appears* that 4.33 is inheriting its default ciphers from whatever the installed OpenSSL uses by default. Is that correct? If I set ciphers to "ALL" under 4.43 would the running stunnel be using the same cipher list as the 4.33 build we were running previously? Thanks, Brian P.S. - No need to discuss the wisdom of our cipher list at the moment... I just want to get this client functioning and then worry about The Right Thing To Do.

Why 6 processes for single client-mode service configuration?
by Grant Edwards 12 Oct '11

12 Oct '11

I'm configuring stunnel to encrypt a single client-mode connection: client = yes foreground = yes syslog = yes pid = [stunnel-localhost] accept = localhost:4608 connect = localhost:4606 Why does that result in _six_ stunnel processes? [one parent and 5 children]? It's going to look a ridiculous if I have four instances like that configured and end up with _24_ stunnel processes. I can see two processes (one for data flowing in each direction) but six seems way overboard. -- Grant Edwards grant.b.edwards Yow! I feel like a wet at parking meter on Darvon! gmail.com

Hi, I've updated the sendproxy patch from (http://haproxy.1wt.eu/ and http://haproxy.1wt.eu/download/patches/stunnel-4.33-exceliance-aloha-sendpr…) to stunnel 4.44 I'd appreciate it if this patch would be included in stunnel proper. -- Mark Janssen -- maniac(at)maniac.nl Unix / Linux Open-Source and Internet Consultant Maniac.nl Sig-IO.nl Vps.Stoned-IT.com

stunnel 4.35 hangs on slackware64 13.37
by crocket 11 Oct '11

11 Oct '11

If I rotate stunnel logs with logrotate and have logrotate send SIGUSR1 signal to stunnel, stunnel doesn't close and reopen a new log and hangs. If I rotate stunnel logs and have logrotate send SIGHUP to stunnel, stunnel writes two lines to a new log but hangs after then. It could be a CPU problem because my D525 ATOM CPU had a problematic history with other programs. But I'm not sure of this. Can anybody else reproduce the problem?

stunnel.exe stops connecting
by Mike Brazil 27 Sep '11

27 Sep '11

I'm running stunnel 4.44 for both POP3 and SMTP with my email client, Outlook Express, and my Spam filter, Cactus Spam. The OS is Win XP SP3. I have added the following to stunnel.conf: client = yes debug = debug [pop3s] accept = 127.0.0.1:11010 connect = camel.arvixe.com:995 [ssmtp] accept = 25 connect = camel.arvixe.com:465 Other than adding those lines, I've not changed anything in the rest of stunnel.conf as it comes with the program. When I boot the computer, Outlook Express, Cactus Spam, and stunnel all start and function correctly. However, after a period of time (a few hours -- I haven't yet pinned down whether there is a specific length to the time period), something goes wrong with stunnel, in that it stops communicating with Outlook Express, and it's CPU usage goes up to 25% (quad-core Intel CPU) and stays at that level indefinitely until I terminate the process. It is only the stunnel.exe process that is affected -- the service continues to run without error. I then restart stunnel.exe, and it works normally once again for a few hours. I usually become aware that stunnel has stopped connecting with Outlook Express when I come back to the computer after a few hours away from it, so I have so far been unable to see whether anything observable occurs when it gets into trouble or whether the length of time it ran properly varies or is constant. -- Mike Brazil mike(a)milibra.net

stunnel 4.44 - tools/Makefile $(ssldir) vs $(SSLDIR)
by Sebastian Kayser 27 Sep '11

27 Sep '11

Hi, I am building a recent stunnel version for Solaris via opencsw.org and with 4.44 it seems as if --with-ssl is used to AC_SUBST([SSLDIR]), yet tools/Makefile uses lowercase $(ssldir). Lead to an empty expansion and failed calls to openssl in my case. $ grep -i ssldir Makefile tools/Makefile Makefile:SSLDIR = /opt/csw tools/Makefile:SSLDIR = /opt/csw tools/Makefile:openssl = $(ssldir)/bin/openssl Sebastian
