Download page broken

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
by WNSDEV 26 Feb '15

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. I'm not sure exactly what the issue is here.. can anyone explain what the conflict is?

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?
by shanmuganathan sedukumar 20 Feb '15

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

TLSv1 - Linux vs Windows ?
by Brian Ipsen 16 Feb '15

16 Feb '15

Hi I have a strange issue with stunnel 5.09 - which connects up to a F5 loadbalancer/SSL-offloading engine. In my config, I specify that the protocol must be TLSv1 - from Linux, I can connect - but it does not work from Windows..

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

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?

stunnel keeps using SSLv3 even after disabling it
by Or Yarimi 04 Feb '15

04 Feb '15

Hi, I'm using stunnel to communicate with FIX server. In order to do that, I disabled SSLv2 and SSLv3 and set the sslVersion to TLSv1. It seems like stunnel keeps trying using SSLv3 handshake, which isn't working. This is the configuration: client = yes debug = 7 output=stunnel.log cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Turning for LMAX options = NO_SSLv2 options = NO_SSLv3 [LMAX-fix-tunnel-DEMO-Trading] sslVersion = TLSv1 accept = 40001 connect = fix-ate.lmaxtrader.com:443 stunnel log: 2015.02.04 12:10:31 LOG7[12516]: Service [LMAX-fix-tunnel-DEMO-MktData] started 2015.02.04 12:10:31 LOG5[12516]: Service [LMAX-fix-tunnel-DEMO-MktData] accepted connection from 127.0.0.1:59475 2015.02.04 12:10:31 LOG6[12516]: s_connect: connecting 91.215.165.69:443 2015.02.04 12:10:31 LOG7[12516]: s_connect: s_poll_wait 91.215.165.69:443: waiting 10 seconds 2015.02.04 12:10:31 LOG5[12516]: s_connect: connected 91.215.165.69:443 2015.02.04 12:10:31 LOG5[12516]: Service [LMAX-fix-tunnel-DEMO-MktData] connected remote server from 10.0.0.62:59476 2015.02.04 12:10:31 LOG7[12516]: Remote socket (FD=620) initialized 2015.02.04 12:10:31 LOG6[12516]: SNI: sending servername: fix-md-ate.lmaxtrader.com 2015.02.04 12:10:31 LOG7[12516]: SSL state (connect): before/connect initialization 2015.02.04 12:10:31 LOG7[12516]: SSL state (connect): SSLv3 write client hello A Already burned around 4 hours understanding what I'm doing wrong, will be glad if you could help me.

Can't compile stunnel 5.10 on Linux ... got fatal signal 11 error
by amontaron 03 Feb '15

03 Feb '15

Hi everybody ! I tried to compile stunnel 5.10 (latest) on my old Suse 7 Linux distrib and got "a fatal signal 11 error message" when doing the make command. Just before, openssl 1.0.2 (latest) compile fine with no errors. Also, I add some stuffs like xemacs 21.4.22 (latest) just to say that that rather old distrib is able to do all that :-D So, here is the latest messages from make I got : > Making all in src > make[1]: Entering directory `/root/stunnel-5.10/src' > make all-am > make[2]: Entering directory `/root/stunnel-5.10/src' > source='stunnel.c' object='stunnel-stunnel.o' libtool=no \ > DEPDIR=.deps depmode=gcc /bin/sh ../auto/depcomp \ > gcc -DHAVE_CONFIG_H -I. -I/usr/kerberos/include > -I/usr/local/ssl/include -DLIBDIR='"/usr/local/lib/stunnel"' > -DCONFDIR='"/usr/local/etc/stunnel"' -g -O2 -pthread -Wall > -Wformat=2 -Wconversion -Wno-long-long -Wno-deprecated-declarations > -D_FORTIFY_SOURCE=2 -c -o stunnel-stunnel.o `test -f 'stunnel.c' || > echo './'`stunnel.c > In file included from /usr/include/string.h:346, > from common.h:201, > from stunnel.c:38: > /usr/include/bits/string2.h: In function `__strsep_g': > /usr/include/bits/string2.h:1171: warning: passing arg 2 of > `__strpbrk_c2' with different width due to prototype > /usr/include/bits/string2.h:1171: warning: passing arg 3 of > `__strpbrk_c2' with different width due to prototype > /usr/include/bits/string2.h:1171: warning: passing arg 2 of > `__strpbrk_c3' with different width due to prototype > /usr/include/bits/string2.h:1171: warning: passing arg 3 of > `__strpbrk_c3' with different width due to prototype > /usr/include/bits/string2.h:1171: warning: passing arg 4 of > `__strpbrk_c3' with different width due to prototype > gcc: Internal compiler error: program cc1 got fatal signal 11 > make[2]: *** [stunnel-stunnel.o] Error 1 > make[2]: Leaving directory `/root/stunnel-5.10/src' > make[1]: *** [all] Error 2 > make[1]: Leaving directory `/root/stunnel-5.10/src' > make: *** [all-recursive] Error 1 Previously got lots of warning messages. Perhaps need "make report" also ? I've look at stunnel-users(a)stunnel.org mail archive up to July 2011 with no success. So, that's why I'm writting to you there... Then, I tried different versions of stunnel 4.xx like 4.00, 4.56, 4.28 and more. All simply don't compile with differents errors messages. The only one I could compile completly is stunnel 3.22 (so latest 3.xx) Note that I'm happy with that because I was running stunnel 3.3 just before and that everything works with the latest openssl version I download and everything works fine for what I would ! Remark: Suse7 distrib (not OpenSuse) is Linux 2.2.16 kernel (not latest :-D) Alex. PS: Another things, on the same machine I ran stunnel 4.56 on (old) Windows 98 with no problems. --- Ce courrier électronique ne contient aucun virus ou logiciel malveillant parce que la protection avast!

stunnel log shows SSLv3 protocol level even when TLSv1 was negotiated
by christian.tenvenne＠lhsystems.com 03 Feb '15

03 Feb '15

I'm running stunnel in server-mode with options "NO_SSLV2" and "NO_SSLV3" and sslVersion=all. My client also explicitly disables SSLv2 and SSLv3. My client's ssl-log (-Djavax.net.debug=ssl) confirms that, during handshake and for application data, the highest TLS protocol version is being used. How come, stunnel log still shows "SSLv3" ? 2015.02.03 14:42:46 LOG5[8415:140561397376768]: ldaps-in accepted connection from X.X.X.X:65158 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): before/accept initialization 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 read client hello A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 write server hello A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 write certificate A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 write server done A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 flush data 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 read client key exchange A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 read finished A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 write change cipher spec A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 write finished A 2015.02.03 14:42:46 LOG7[8415:140561397376768]: SSL state (accept): SSLv3 flush data 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 9 items in the session cache 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 client connects (SSL_connect()) 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 client connects that finished 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 client renegotiations requested 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 12 server connects (SSL_accept()) 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 9 server connects that finished 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 server renegotiations requested 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 session cache hits 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 external session cache hits 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 session cache misses 2015.02.03 14:42:46 LOG7[8415:140561397376768]: 0 session cache timeouts 2015.02.03 14:42:46 LOG6[8415:140561397376768]: SSL accepted: new session negotiated 2015.02.03 14:42:46 LOG6[8415:140561397376768]: Negotiated ciphers: AES128-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(128) Mac=SHA1 Is my client's ssl-log wrong?
