Laurent, We need to present a client certificate to the server. That's the important part missing. Do that by adding -cert your_cert_filename to the command, like: openssl s_client -ssl3 -state -cert your_client_cert_filename -connect your-stunnel-ip:10443 See http://www.openssl.org/docs/apps/s_client.html Regards, Jose ________________________________ From: "laurent.uk(a)bnpparibas.com" <laurent.uk(a)bnpparibas.com> To: josealf(a)rocketmail.com Cc: stunnel-users(a)stunnel.org; stunnel-users-bounces(a)stunnel.org Sent: Wed, May 4, 2011 6:55:19 AM Subject: Réf. : Re: Réf. : Re: Réf. : Re: [stunnel-users] need help error :SSL3_GET_RECORD:wrong versionnumber with cipher DES-CBC-SHA Jose, thanks you for your response, i use the openssl s_client command but i have the following error : 1499296:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:162:filename(libz.so): Could not load module .

Hi, If you have control of both ends of the connection make sure your SSL version is consistent on both sides. I would not recomend using sslVersion = all Either set it to SSLv3 or TLSv1 DES-CBC-SHA is supported under those However, judging for the cipher you are choosing I assume you might be dealing with a legacy application and you might not have access to both ends of the connection. I would try setting only one version at the time and moving down from TLSv1, SSLv3 and SSLv2 sslVersion = ciphers = DES-CBC-SHA Cheers ----------------- Leandro Avila ________________________________ From: "laurent.uk(a)bnpparibas.com" <laurent.uk(a)bnpparibas.com> To: josealf(a)rocketmail.com Cc: stunnel-users(a)stunnel.org; stunnel-users-bounces(a)stunnel.org Sent: Tuesday, May 3, 2011 10:48 AM Subject: [stunnel-users] Réf. : Re: need help error :SSL3_GET_RECORD:wrong versionnumber with cipher DES-CBC-SHA Dear Jose, here is the configuration file of my stunnel : ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration ; Please make sure you understand them (especially the effect of chroot jail) ; Certificate/key is needed in server mode and optional in client mode cert = /opt/freeware/etc/stunnel/ca_nopass.pem foreground = yes syslog = yes ; Protocol version (all, SSLv2, SSLv3, TLSv1) ;sslVersion = SSLv2 sslVersion = all ;ciphers = DES-CBC-SHA ;ciphers = DES-CBC3-SHA:IDEA-CBC-MD5 ; Some security enhancements for UNIX systems - comment them out on Win32 ;chroot = /usr/local/stunnel/var/lib/stunnel ;chroot = /tmp/ ;setuid = root ;setgid = other ; PID is created inside chroot jail pid = /var/adm/stunnel_server_level1.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ;compression = rle ; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS ;options = Options_SSL ; Authentication stuff verify = 3 ; Don't forget to c_rehash CApath ; CApath is located inside chroot jail CApath = /opt/freeware/etc/stunnel/CA_files/ ; It's often easier to use CAfile ;CAfile = /opt/freeware/etc/stunnel/ca.pem ; Don't forget to c_rehash CRLpath ; CRLpath is located inside chroot jail ;CRLpath = /crls ; Alternatively you can use CRLfile ;CRLfile = /usr/local/stunnel/etc/stunnel/crls.pem ; Some debugging stuff useful for troubleshooting debug = 7 ; Use it for client mode client = no ; Service-level configuration [pesitip] accept = 10443 connect = XXXXXXX:10016 Thanks for your help.

Dear Users, Version 4.36 of stunnel was released. The ChangeLog entry: Version 4.36, 2011.05.03, urgency: LOW: * New features - Updated Win32 DLLs for OpenSSL 1.0.0d. - Dynamic memory management for strings manipulation: no more static STRLEN limit, lower stack footprint. - Strict public key comparison added for "verify = 3" certificate checking mode (thx to Philipp Hartwig). - Backlog parameter of listen(2) changed from 5 to SOMAXCONN: improved behavior on heavy load. - Example tools/stunnel.service file added for systemd service manager. * Bugfixes - Missing pthread_attr_destroy() added to fix memory leak (thx to Paul Allex and Peter Pentchev). - Fixed the incorrect way of setting FD_CLOEXEC flag. - Fixed --enable-libwrap option of ./configure script. - /opt/local added to OpenSSL search path for MacPorts compatibility. - Workaround implemented for signal handling on MacOS X. - A trivial bug fixed in the stunnel.init script. - Retry implemented on EAI_AGAIN error returned by resolver calls.

Laurent, Can you post your configuration? For security, You should change the real IPs (but not the ports) before posting. You can check: 1. Does your stunnel client config has client=yes? 2. Does your stunnel server config has client=no 3. Check your packet flow, that is: your accept/connect settings.
