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?

Re: [stunnel-users] Centos 6.6 Final stunnel-4.29-3.el6_6.1.x86_64 - options set problem SSLv3

Hi Mike, thanks for your fast response, but I think there is a big issue. The latest version that is available in the CENTOS 6 Base Repo is "stunnel-4.29-3.el6_6.1.x86_64" - In this version the SSLv3 is disabled by default, but there is not option to enable it. I hope you understand my situation :-) ________________________________ Von: stunnel-users <stunnel-users-bounces(a)stunnel.org> im Auftrag von Michal Trojnara <Michal.Trojnara(a)mirt.net> Gesendet: Donnerstag, 29.

Hi Mike, yes your correct, but I have forced the installation with "stunnel-4.29-3.el6_4.x86_64" ( all other packages openssl, etc. updated) and SSLv3 is working again. So, for my understanding there must be a bug or they have disabled SSLv3 in version "stunnel-4.29-3.el6_6.1.x86_64".

Anyway, if you connect stunnel with some software that's so old that it doesn't support TLS, the software is almost certainly no longer supported, and most likely vulnerable to attacks. This is a serious risk! Mike On 29.01.2015 11:58, Sebastian Ochsenkühn wrote: Hi Mike, thanks for your fast response, but I think there is a big issue.

Blue Iris

22 Jan '15

I have stunnel set up on my machine. It works locally and lets me connect to my Blue Iris server with https. However, I am unable to do this remotely. I have forwarded the port in my router to stunnel, from stunnel to blue iris, but still doesn't work. Below is part of my conf file [Blue Iris] accept = 8344 (forwarded this in the router to my static IP of my machine) connect = 127.0.0.1:8081 (8081 is my blue iris web server) I hope someone is able to give some advice

Re: [stunnel-users] No DNS lookup?

Ludolf, Thanks for your quick response. I have no clue on how to respond on the stunnel users list, so i'll try it this way. The support on the host we are trying to reach states to following: It really sounds like the stunnel is not connecting to "something.host.com" but perhaps to the IP address behind it? The use of the hostname something.host.com is however an requirement. Is there anyway we can force the stunnel to connect to the hostname instead of resolving it as an IP adress?
