STunnel v5.11 Multi SNI
by Scott McKeown 17 Mar '15

17 Mar '15

Hi Guys, I've got a small issue where I'm trying to use multiple SNI rules in an STunnel frontend: STunnel Version is: stunnel -version stunnel 5.11 on x86_64-unknown-linux-gnu platform Compiled/running with OpenSSL 1.0.1e 11 Feb 2013 Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI Global options: debug = daemon.notice RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options: ciphers = FIPS (with "fips = yes") ciphers = HIGH:MEDIUM:+3DES:+DH:!aNULL:!SSLv2 (with "fips = no") curve = prime256v1 options = NO_SSLv2 options = NO_SSLv3 sessionCacheSize = 1000 sessionCacheTimeout = 300 seconds stack = 65536 bytes TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none stunnel.conf is: [https] accept = 443 connect = 80 [www_test] sni = https:test.com sni = https:www.test.com connect = 192.168.64.220:80 [testing] sni = https:testing.com sni = https:www.testing.com connect = 192.168.64.253:80 I've created local DNS rules for each of these Hosts but the problem is that only the last entered sni rule gets matched so for example www.test.com works but test.com does not. Its the same for testing.com and www.testing.com This is what the log file show too: 2015.03.03 20:01:19 LOG7[12776]: Service [https] accepted (FD=21) from 192.168.63.50:53123 2015.03.03 20:01:19 LOG7[12808]: Service [https] started 2015.03.03 20:01:19 LOG5[12808]: Service [https] accepted connection from 192.168.63.50:53123 2015.03.03 20:01:19 LOG7[12808]: SSL state (accept): before/accept initialization 2015.03.03 20:01:19 LOG6[12808]: SNI: requested servername: testing.com 2015.03.03 20:01:19 LOG3[12808]: SNI: no pattern matched servername: testing.com 2015.03.03 20:01:19 LOG7[12808]: SSL alert (write): fatal: unrecognized name 2015.03.03 20:01:19 LOG3[12808]: SSL_accept: 1408A0E2: error:1408A0E2:SSL routines:SSL3_GET_CLIENT_HELLO:clienthello tlsext 2015.03.03 20:01:19 LOG5[12808]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket 2015.03.03 20:01:19 LOG7[12808]: Local socket (FD=21) closed 2015.03.03 20:01:19 LOG7[12808]: Service [https] finished (7 left) 2015.03.03 20:01:29 LOG6[12805]: Read socket closed (readsocket) 2015.03.03 20:01:29 LOG7[12805]: Sending close_notify alert 2015.03.03 20:01:29 LOG7[12805]: SSL alert (write): warning: close notify 2015.03.03 20:01:29 LOG6[12805]: SSL_shutdown successfully sent close_notify alert 2015.03.03 20:01:30 LOG6[12805]: SSL socket closed (SSL_read) 2015.03.03 20:01:30 LOG7[12805]: Sent socket write shutdown 2015.03.03 20:01:30 LOG5[12805]: Connection closed: 485 byte(s) sent to SSL, 642 byte(s) sent to socket 2015.03.03 20:01:30 LOG7[12805]: Remote socket (FD=14) closed 2015.03.03 20:01:30 LOG7[12805]: Local socket (FD=13) closed 2015.03.03 20:01:30 LOG7[12805]: Service [www_test] finished (6 left) 2015.03.03 20:01:49 LOG7[12776]: Service [https] accepted (FD=13) from 192.168.63.50:53128 2015.03.03 20:01:49 LOG7[12809]: Service [https] started 2015.03.03 20:01:49 LOG5[12809]: Service [https] accepted connection from 192.168.63.50:53128 2015.03.03 20:01:49 LOG7[12809]: SSL state (accept): before/accept initialization 2015.03.03 20:01:49 LOG6[12809]: SNI: requested servername: testing.com 2015.03.03 20:01:49 LOG3[12809]: SNI: no pattern matched servername: testing.com 2015.03.03 20:01:49 LOG7[12809]: SSL alert (write): fatal: unrecognized name 2015.03.03 20:01:49 LOG3[12809]: SSL_accept: 1408A0E2: error:1408A0E2:SSL routines:SSL3_GET_CLIENT_HELLO:clienthello tlsext 2015.03.03 20:01:49 LOG5[12809]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket 2015.03.03 20:01:49 LOG7[12809]: Local socket (FD=13) closed 2015.03.03 20:01:49 LOG7[12809]: Service [https] finished (6 left) I have seen a couple of patch files floating around but they are for older versions and I can't get them to compile into the v5.11 version.

SSH connection problems inside stunnel
by debian＠bercot.org 13 Mar '15

13 Mar '15

Hello, I've installed a stunnel between my laptop and my server (both in Debian SID) [v5.06-2]. Here is my client stunnel.conf : pid = /var/run/stunnel.pid client = yes sslVersion = TLSv1.2 debug = 7 [ssh] accept = 5000 protocol = connect protocolHost = myserver:443 connect = myproxy:8080 The server one : cert = mycert key = mykey chroot = /var/lib/stunnel4/ setuid = stunnel4 setgid = stunnel4 pid = /stunnel4.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 sslVersion = TLSv1.2 ; https ou ssh encapsulé dans du ssl [sslh] accept = 443 connect = myserver:444 And my .ssh/config : Host myserver HostName localhost Port 5000 IdentityFile ~/.ssh/mykey ProtocolKeepAlives 6 At home (I use tinyproxy to test), everything is OK. At work, with a "true" proxy, sometimes I can connect (but I'm quickly disconnected), sometimes I can't... I've watch the logs but find nothing. Do you have any idea ? Something to look in the logs ? Here is an example of a short connection : ~ $ ssh myserver root@myserver:~# cat /var/log/syslog | grep stunnel [...] root@myserver~# Timeout, server localhost not responding. More often I have : ~ $ ssh myserver ssh_exchange_identification: Connection closed by remote host In my local logs : Mar 12 13:24:41 mylaptop stunnel: LOG7[3984]: Service [ssh] accepted (FD=3) from 127.0.0.1:44794 Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: Service [ssh] started Mar 12 13:24:41 mylaptop stunnel: LOG5[3223]: Service [ssh] accepted connection from 127.0.0.1:44794 Mar 12 13:24:41 mylaptop stunnel: LOG6[3223]: s_connect: connecting myproxy:8080 Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: s_connect: s_poll_wait myproxy:8080: waiting 10 seconds Mar 12 13:24:41 mylaptop stunnel: LOG5[3223]: s_connect: connected myproxy:8080 Mar 12 13:24:41 mylaptop stunnel: LOG5[3223]: Service [ssh] connected remote server from myIP:58282 Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: Remote socket (FD=8) initialized Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: -> CONNECT myserver:443 HTTP/1.1 Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: -> Host: myserver:443 Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: -> Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: <- HTTP/1.1 200 Connection established Mar 12 13:24:41 mylaptop stunnel: LOG6[3223]: CONNECT request accepted Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: <- Mar 12 13:24:41 mylaptop stunnel: LOG6[3223]: SNI: sending servername: myserver Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: SSL state (connect): before/connect initialization Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: SSL state (connect): unknown state Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: SSL state (connect): unknown state Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: SSL state (connect): unknown state Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: SSL state (connect): unknown state Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: SSL state (connect): unknown state Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: SSL state (connect): unknown state Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 54 items in the session cache Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 109 client connects (SSL_connect()) Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 110 client connects that finished Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 0 client renegotiations requested Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 0 server connects (SSL_accept()) Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 0 server connects that finished Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 0 server renegotiations requested Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 56 session cache hits Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 0 external session cache hits Mar 12 13:24:41 mylaptop stunnel: LOG7[3223]: 0 session cache misses Mar 12 13:24:43 mylaptop stunnel: LOG7[3223]: SSL alert (read): warning: close notify Mar 12 13:24:43 mylaptop stunnel: LOG6[3223]: SSL closed (SSL_read) Mar 12 13:24:43 mylaptop stunnel: LOG7[3223]: Sent socket write shutdown Mar 12 13:24:43 mylaptop stunnel: LOG6[3223]: Read socket closed (readsocket) Mar 12 13:24:43 mylaptop stunnel: LOG6[3223]: Read socket closed (hangup) Mar 12 13:24:43 mylaptop stunnel: LOG6[3223]: Write socket closed (hangup) Mar 12 13:24:43 mylaptop stunnel: LOG7[3223]: Sending close_notify alert Mar 12 13:24:43 mylaptop stunnel: LOG7[3223]: SSL alert (write): warning: close notify Mar 12 13:24:43 mylaptop stunnel: LOG6[3223]: SSL_shutdown successfully sent close_notify alert Mar 12 13:24:43 mylaptop stunnel: LOG5[3223]: Connection closed: 32 byte(s) sent to SSL, 0 byte(s) sent to socket Mar 12 13:24:43 mylaptop stunnel: LOG7[3223]: Remote socket (FD=8) closed Mar 12 13:24:43 mylaptop stunnel: LOG7[3223]: Local socket (FD=3) closed Mar 12 13:24:43 mylaptop stunnel: LOG7[3223]: Service [ssh] finished (0 left) Thank you.

Dear all, Downloads on https://www.stunnel.org/downloads.html seem to be broken. Clicking any link brings one back to the Downloads page (serves the downloads.html file). I noticed when deploying Streisand ( https://github.com/jlund/streisand ), which mirrors stunnel on each installation. Best, Lukas

Re: [stunnel-users] [stunnel-announce] stunnel 5.10 released - Problem compiling stunnel 5.10 with openssl 1.0.2

stunnel 5.10 openssl 1.0.2 Ubuntu 10.04 Server lucid after installing automake-1.14.1 (required as of 5.08) and running configure without a problem, make fails with this message: /usr/bin/ld: /ssl-1.0.2/lib/libssl.a(s2_srvr.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC /ssl-1.0.2/lib/libssl.a: could not read symbols: Bad value I can resolve this issue by commenting the assignment of CFLAGS and LDFLAGS in the stunnel configure script so -fPIE and -pie -fPIE are not implemented. # stunnel_CFLAGS="$stunnel_CFLAGS -fPIE" # stunnel_LDFLAGS="$stunnel_LDFLAGS -pie -fPIE" This is not required in stunnel 5.07 or earlier versions.

Gmail POP3 retrieval, SSL-Error and Cert Chain
by Tobias Ruch 24 Feb '15

24 Feb '15

Hi, I want to use stunnel to enable ssl on port 995. Unfortunately, I got "SSL error: Unable to verify the first certificate." when using the gmail pop3 retrieval My Certificate is signed by wosign and included in the mozialla truststore list. https://www.ssllabs.com/ssltest/analyze.html gives me a grad A for my apache configuration and chrome and firefox are also fine with this certificate. So it's no self signed one. For a test I have configured stunnel to serve https. I get than the message that the chain is incomplete. According to https://www.digicert.com/ssl-support/gmail-pop3-troubleshooting.htm this could be one reason for this error. My Apache-config looks like this SSLCertificateFile /etc/apache2/ssl/mydomain.crt SSLCertificateKeyFile /etc/apache2/ssl//mydomain.key SSLCertificateChainFile /etc/apache2/ssl/1_root_bundle.crt SSLCACertificateFile /etc/apache2/ssl/ca-certs.pem for stunnel I used cert = /etc/apache2/ssl/mydomain.crt key = /etc/apache2/ssl//mydomain.key CAfile = /etc/apache2/ssl/1_root_bundle.crt or ca-certs.pem (I have tried both). What is the a similar configuration in stunnel? The Post https://www.stunnel.org/pipermail/stunnel-users/2010-February/002594.html mentioned, that the chain must be completely in the crt-file. But a description how to achieve this is missing and I found no other resources describing this. Thanks a lot Tobias

Stunnel for EWS servers?

20 Feb '15

HI, We are already using stunnel as SSL wrapper for retrieving emails from POP3 servers to our application server. In future the mailboxes are planned to be migrated to EWS servers. Would like to know if stunnel holds good for EWS servers as well. Regards,Shanmuganathan

stunnel transparent mode stuck in timeout
by shushant.kakkar＠lhsystems.com 09 Feb '15

Hi, we would like to use stunnel in transpartent mode. Therefore we already applied iptable changes as mentioned in the man page : Re-write address to appear as if wrapped daemon is connecting from the SSL client machine instead of the machine running stunnel. This option is currently available in: remote mode (I<connect> option) on Linux >=2.6.28 Linux >=2.6.28 requires the following setup for iptables and routing (possibly in /etc/rc.local or equivalent file): iptables -t mangle -N DIVERT iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT iptables -t mangle -A DIVERT -j MARK --set-mark 1 iptables -t mangle -A DIVERT -j ACCEPT ip rule add fwmark 1 lookup 100 ip route add local 0.0.0.0/0 dev lo table 100 However the connection to the services cannot be established and we run into a timeout. 2015.02.09 10:00:03 LOG7[6658:139940568909760]: ldaps-in accepted FD=12 from xxxxxx:51018 2015.02.09 10:00:03 LOG7[6658:139940568905472]: ldaps-in started 2015.02.09 10:00:03 LOG7[6658:139940568905472]: FD 12 in non-blocking mode 2015.02.09 10:00:03 LOG7[6658:139940568905472]: Waiting for a libwrap process 2015.02.09 10:00:03 LOG7[6658:139940568905472]: Acquired libwrap process #0 2015.02.09 10:00:03 LOG7[6658:139940568905472]: Releasing libwrap process #0 2015.02.09 10:00:03 LOG7[6658:139940568905472]: Released libwrap process #0 2015.02.09 10:00:03 LOG7[6658:139940568905472]: ldaps-in permitted by libwrap from xxxxxxx:51018 2015.02.09 10:00:03 LOG5[6658:139940568905472]: ldaps-in accepted connection from xxxxxxx:51018 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): before/accept initialization 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 read client hello A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 write server hello A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 write certificate A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 write server done A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 flush data 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 read client key exchange A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 read finished A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 write change cipher spec A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 write finished A 2015.02.09 10:00:03 LOG7[6658:139940568905472]: SSL state (accept): SSLv3 flush data 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 1 items in the session cache 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 client connects (SSL_connect()) 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 client connects that finished 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 client renegotiations requested 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 1 server connects (SSL_accept()) 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 1 server connects that finished 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 server renegotiations requested 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 session cache hits 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 external session cache hits 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 session cache misses 2015.02.09 10:00:03 LOG7[6658:139940568905472]: 0 session cache timeouts 2015.02.09 10:00:03 LOG6[6658:139940568905472]: SSL accepted: new session negotiated 2015.02.09 10:00:03 LOG6[6658:139940568905472]: Negotiated ciphers: AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 2015.02.09 10:00:03 LOG7[6658:139940568905472]: FD 13 in non-blocking mode 2015.02.09 10:00:03 LOG6[6658:139940568905472]: local_bind succeeded on the original port 2015.02.09 10:00:03 LOG6[6658:139940568905472]: connect_blocking: connecting 127.0.0.1:10389 2015.02.09 10:00:03 LOG7[6658:139940568905472]: connect_blocking: s_poll_wait 127.0.0.1:10389: waiting 10 seconds 2015.02.09 10:00:13 LOG3[6658:139940568905472]: connect_blocking: s_poll_wait 127.0.0.1:10389: timeout 2015.02.09 10:00:13 LOG5[6658:139940568905472]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2015.02.09 10:00:13 LOG7[6658:139940568905472]: ldaps-in finished (0 left) Any idea why the timeout is occuring?
