Morning All, Can someone tell me from what version(s) of STUNNEL fully support UTF-8? Thanks, Greg Gregory J.

Patch for XMPP in client mode
by Philipp Hartwig 05 May '11

05 May '11

Hi, I've attached a small patch which adds support for the XMPP protocol in client mode. It does pretty much what Brian Hatch has outlined under [1]. I've tested it with several Jabber servers and it seems to work nicely. I'd be very happy about any comments. Regards, Philipp [1] http://stunnel.mirt.net/pipermail/stunnel-users/2009-February/002278.html

transparent = source, stunnel connect always times out
by Robert Hardy 05 May '11

05 May '11

I've been fighting with stunnel, trying to get its transparent proxy support to work. No matter what I do, as soon as transparent = source support is turned on, tests with my mail client just time out. If I turn transparent proxy support off it works but appears as if connections are from localhost, which is undesirable. My goal is to have stunnel listen on *:465 and provide SSL protected connectivity, which appear to arrive from the remote client IP, on my mail server's external IP address on port 25. My mail server and the firewall with the rules on it are the same physical machine. Can someone please make some suggestions as to what else I can try to get this working? I'm running Linux 2.6.38 on a current CentOS/rhel5 box and I've got modules built for most netfilter options, including: NF_CONNTRACK=m NETFILTER_TPROXY=m NETFILTER_XT_MATCH_SOCKET=m NETFILTER_XT_TARGET_TPROXY=m /proc/sys/net/ipv4/conf/all/rp_filter = 0 /proc/sys/net/ipv4/ip_forward = 1 This is my stunnel config: cert = /etc/stunnel/assps.crt key = /etc/stunnel/assps.key pid = /var/run/stunnel/stunnel_smtps.pid verify = 0 debug = 7 output = /var/log/stunnel_smtps.log TIMEOUTconnect = 60 [smtps] accept = 465 connect = MY_EXTERNAL_IP:25 transparent = source My stunnel seems happy with the DH Parameters in my cert file.

Hi Laurent, Good to see you figured out the issue. I also learned more things myself. Thanks Jose ! To my knowledge cipher suites that use SHA2 are part of the TLS 1.2 specification but I don't think OpenSSL has that implemented.

But that's not the problem here. It should work as is. Mosty likely the problem is on the client SSL software you are using to connect to stunnel. The cipher you are trying to use DESC-CBC-SHA works with SSLv3 and TLSv1. Can you force your client to use those protocols? Maybe it is trying to negotiate SSLv2. Also are you sure it is speaking SSL instead of plain text? You can test your connection to stunnel server with openssl s_client command. Example openssl s_client -ssl3 -state -connect your-stunnel-ip:10443 openssl s_client -tls1 -state -connect your-stunnel-ip:10443 if this works, we found the culprit.

Laurent, Everything looks fine to me. Your were connected to the server using SSLv3 and AES256-SHA ciphers. The zlib error can be ignored. Message "Verify return code: 21 (unable to verify the first certificate)" indicates that openssl s_client was unable to verify the server certificate. You can get rid of this by giving the CAPath in the paremters and making sure the verisign root Ca cert is there.

Laurent, Ideally, you should terminate the SSL connection on your final server. But that's not the problem here. It should work as is. Mosty likely the problem is on the client SSL software you are using to connect to stunnel. The cipher you are trying to use DESC-CBC-SHA works with SSLv3 and TLSv1. Can you force your client to use those protocols? Maybe it is trying to negotiate SSLv2. Also are you sure it is speaking SSL instead of plain text? You can test your connection to stunnel server with openssl s_client command. Example openssl s_client -ssl3 -state -connect your-stunnel-ip:10443 openssl s_client -tls1 -state -connect your-stunnel-ip:10443 if this works, we found the culprit.

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.

stunnel 4.36 released
by Michal Trojnara 03 May '11

03 May '11

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. Home page: http://www.stunnel.org/ Download: ftp://ftp.stunnel.org/stunnel/ SHA-256 hash for stunnel-4.36.tar.gz: 3483fc2011e8a9d2614a93a9dbf7eabf405044df3566f29144fe2d1dd37a35f5 Best regards, Mike
