stunnel with Fedora core
by Andy 17 Jan '08

17 Jan '08

Hello everyone I am trying to configure stunnel on a Fedora Core machine, but have had little luck. The below configuration is in the /etc/stunne/stunnel.conf. I want this machine to send encrypted data to another machine via stunnel. My knowledge of stunnel is quite limited. chroot = /home/stunnel pid = /stunnel.pid setuid = stunnel setgid = stunne; debug = 7 output = /var/log/messages client = yes [ldap] accept = 389 connect = ldap.example.com:636 I have been told that this command will work. stunnel -c -d ldaps -r <LDAPSERVER>:ldaps This command does work under debian but does not work under fedora core. Can anyone help me with this? -- REGARDS, Andy

Debian Bug#460019: cert= produces output on stderr even with log= set
by Luis Rodrigo Gallardo Cruz 16 Jan '08

16 Jan '08

----- Forwarded message from Bryan Donlan <bd(a)fushizen.net> ----- Version: 3:4.21-1 With the following configuration: output = /srv/stun/log compression = zlib CApath = /srv/stun/keys cert = /srv/stun/server.pem connect = localhost:9999 verify = 3 The following is output on stderr: 2008.01.10 02:54:19 LOG5[11786:3083495088]: Peer certificate location /srv/stun/keys This confuses clients when stunnel is driven direcly from xinetd. This output, if it is produced at all, should be placed in the log file. ----- End forwarded message ----- The issue is that verify_init (verify.c:103) calls s_log(LOG_NOTICE, "Peer certificate location %s", section->ca_dir); apparently before the logfile is setup. Could the log file initialization be moved earlier in the starup sequence? Or maybe this log call's severity could be lowered.

Nessus crashes stunnel
by Joe Kemp 16 Jan '08

16 Jan '08

I am running some tests against my stunnel configuration with Nessus. I am able to get stunnel to exit silently when I run Nessus with the Nessus TCP Scan and Weak Supported SSL Cipher Suites test. I have played with a few different options but the process consistently ends when these tests are run together. Here is the config: Linux testssl.capwin.net 2.6.18-53.1.4.el5 #1 SMP Fri Nov 30 00:45:16 EST 2007 i686 i686 i386 GNU/Linux gcc version 4.1.2 20070626 (Red Hat 4.1.2-14) stunnel 4.20 on i686-pc-linux-gnu with OpenSSL 0.9.8b 04 May 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv4 Auth:LIBWRAP OpenSSL 0.9.8b 04 May 2006 Tail of log file during nessus tests 2008.01.15 21:24:30 LOG5[10646:3086605200]: XMPP accepted connection from 10.102.11.250:41781 2008.01.15 21:24:30 LOG7[10646:3086605200]: SSL state (accept): before/accept initialization 2008.01.15 21:24:30 LOG7[10646:3086605200]: SSL alert (write): fatal: handshake failure 2008.01.15 21:24:30 LOG3[10646:3086605200]: SSL_accept: 1408A10B: error:1408A10B:SSL routines:SSL3_GET_CLIENT_HELLO:wrong version number 2008.01.15 21:24:30 LOG5[10646:3086605200]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2008.01.15 21:24:30 LOG7[10646:3086605200]: XMPP finished (0 left) 2008.01.15 21:24:30 LOG7[10646:3086608080]: XMPP accepted FD=7 from 10.102.11.250:41782 2008.01.15 21:24:30 LOG7[10646:3086605200]: XMPP started 2008.01.15 21:24:30 LOG7[10646:3086605200]: FD 7 in non-blocking mode 2008.01.15 21:24:30 LOG7[10646:3086605200]: TCP_NODELAY option set on local socket 2008.01.15 21:24:30 LOG7[10646:3086605200]: FD 8 in non-blocking mode 2008.01.15 21:24:30 LOG7[10646:3086605200]: FD 9 in non-blocking mode 2008.01.15 21:24:30 LOG7[10646:3086608080]: Cleaning up the signal pipe 2008.01.15 21:24:30 LOG6[10646:3086608080]: Child process 10676 finished with code 0 2008.01.15 21:24:30 LOG7[10646:3086605200]: Connection from 10.102.11.250:41782 permitted by libwrap 2008.01.15 21:24:30 LOG5[10646:3086605200]: XMPP accepted connection from 10.102.11.250:41782 2008.01.15 21:24:30 LOG7[10646:3086605200]: SSL state (accept): before/accept initialization Joe A.

The following is an educated guess: Open connections are open file descriptors, and fork()/exec() do not close open file descriptors. Thus, stunnel is inheriting the open connection. And, since it knows nothing about it, it does not close it or anything like that. So it's not that it activelly listens on it, but only that it does not bother to stop. You might check this theory by trying to connect to the port *after* apache is shut down. If I'm right you should get no answer at all. So, the solution is to have the file descriptors close when exec'ing stunnel. PHP or apache might have some option somewhere to do that (look for "close on exec" or something similarly named), but if not, you might have to write some sort of wrapper to do it. It's a messy thing, because AFAIK there's no clean way to do it short of for (i = 0; i < [some-hopefuly-large-enough-value]; i++) close(i); where the [large-enough-value] is determined by your system's file descriptor limit and your desire not to loop all the way to 2^32 or something. -- Rodrigo i-think-this-time-i-answered-the-question-asked Gallardo GPG-Fingerprint: 7C81 E60C 442E 8FBC D975 2F49 0199 8318 ADC9 BC28

stunnel automatically listening to extra ports: BAD
by Alan Pinstein 11 Jan '08

11 Jan '08

Hi All- I am using stunnel to secure a connection between a local python script using telnetlib and a custom sockets-based server requiring SSL, from local port 4449 to remote port 4449. This is done via: stunnel /opt/www/domains/admin.showcasere.com/showcase/classes/ opensrs-php/stunnel-app.conf where the conf file is: > client = yes > pid = /opt/www/domains/admin.showcasere.com/runtime/stunnel.pid > debug = 7 > [telnet] > accept = 4449 > connect = admin.hostedemail.com:4449 Functionally, everything works for my application, but I am experiencing a bad side-effect. stunnel is ALSO setting up listeners on HTTP and HTTPS ports, and when my daily logrotate scripts run and HUP apache, stunnel steals the web server's ports and the server won't come back up! I had 7 hours of downtime today because of this. I've done a bunch of debugging and can't figure out what's going on. I have only one guess: stunnel automatically listens on any ports that the process calling stunnel is listening on, in some sort of attempt to seamlessly add SSL to existing daemons. I can't find any docs or tell from the source code, but it's the only idea I can't rule out... Here is the debug log of the startup of stunnel (which is run from an apache/php script): Jan 11 13:10:13 bigwoody stunnel: LOG5[13964:3086333632]: stunnel 4.14 on i386-redhat-linux-gnu

You sent the private keys too - you shouldn't do this. You should create new keys when done debugging this problem. I saw only 2 keys - the CA and the stunnel.pem. Your configuration specifies 3 keys, the CA, stunnel.pem, and is attempting to verify the SSL client (browser? something else) against the CA via the 'verify=' line. What is the SSL client? Did you generate a key for it? Because your config is requiring the SSL client authenticate itself, and Stunnel is dropping the connection because that phase isn't working correctly. -- Brian Hatch "So, what's the problem?"

Can you shoot the public keys of the client (which is not on this machine) and the ca.pem and the public key from userkey.pem (which is actually the server's key - you may wish to rename.) There are three pems involved: * the CA key (private) and cert (public) in ca.pem * the stunnel server's key (private) and cert (public) in userkey.pem. ('userkey' is a bad name here.) * the client's key (private) and cert (public) on 192.168.1.5. Can you send the public parts here so I can verify that they're signed by the appropritate folks? -- Brian Hatch "Everybody's cute! Systems and Everybody's cute! Security Engineer Even me.

Hi all,I am a new STUNNEL user,I will do 2 secure sockets TCP (Server / Client). I would like to know how to set 'stunnel.conf. I tried but it does not work. Description: ---------- I created a CA root and from this I have created 2 pairs (key and certificate) one for the server and one for the client. You can send me please a config file from a server? Many thanks, Stunnel.config (serveur) ----------------------- ; Sample stunnel configuration file by Michal Trojnara 2002-2006; Some options used here may not be adequate for your particular configuration ; Certificate/key is needed in server mode and optional in client mode; The default certificate is provided only for testing and should not; be used in a production environment;cert = stunnel.pem;key = stunnel.pemcert = server.crt key = serverkey.key ; Some performance tuningssocket = l:TCP_NODELAY=1socket = r:TCP_NODELAY=1 CAfile = ca.crt ;[Server]accept = 192.168.1.4:4433connect = 192.168.1.4:4433 KHALED Khaled Ingénieur de télécommunications et informatique _________________________________________________________________ Votre contact a choisi Hotmail, l'e-mail nouvelle génération.
