I'm having problems with zlib compression - stunnel 4.07 on my client machne crashes whenever I try and start a session. With compression set to rle or not defined, there is no problem.
I am securing a MySQL connection between a Windows client and Mandrake Linux 10.1 server.
Client Configuration:
Stunnel 4.07 and openssl 0.9.7e-zlib binaries downloaded from Stunnel website
stunnel.conf ------------ cert=./Allan_Guild_Work.pem key=./Allan_Guild_Work_key.pem client=yes compression=zlib
[Primary Club] accept=3306 connect=195.137.78.107:3307 TIMEOUTbusy=5 -------------
Server Configuration:
Stunnel 4.07 and openssl 0.9.7e (compiled with zlib support) rebuilt from Mandrake Cooker SRPMS
stunnel.conf ------------ CApath=/etc/ssl/stunnel/certs/ cert=/etc/ssl/stunnel/CAcert.pem key=/etc/ssl/stunnel/CAkey.pem client=no foreground=yes pid=/var/run/stunnel.pid verify=0 compression=zlib
[Primary Club] accept=3307 connect=3306 ------------
When I try and connect, I get the following output from the client (which then crashes):
------------- 2005.01.11 19:04:14 LOG5[308:2172]: stunnel 4.07 on x86-pc-mingw32-gnu WIN32+IPv4 with OpenSSL 0.9.7e 25 Oct 2004 2005.01.11 19:04:14 LOG5[308:1688]: No limit detected for the number of clients 2005.01.11 19:04:16 LOG5[308:804]: Primary Club connected from 127.0.0.1:4769 -------------
and the following from the server:

Any advice would be greatly appreciated (Do I need a zlib dll?),
Allan
Allan,
When I try and connect, I get the following output from the client (which then crashes):
[cut]
Any advice would be greatly appreciated
Please send us your stack backtrace. http://www.network-theory.co.uk/articles/gccdebug.html
(Do I need a zlib dll?),
No, you don't need dll files on your Mandrake. 8-)
Best regards, Mike
Dear Mike,
Thanks for the reply. I don't have gdb etc. set up on my Windows client at the moment, although I will set up MinGW, if it is needed to get to the bottom of this.
I do however have a Windows Error Log which contains a stack backtrace, and I have attached it below. Please let me know if this is sufficient information.
Best wishes,
Allan
