Hey everyone,

I was going through the stunnel FAQ when I noticed you could add compression. I was very excited and wanted to give it a try but when I tried to add

compression = zlib

to my stunnel.cong I got this error when starting stunnel...

Starting stunnel: file /etc/stunnel/stunnel.conf line 10: Specified option name is not valid here

Line 10 is the exact place where i stuck this name value pair. I don't know where else i could put it, i tried putting it everywhere!

All requested info for posts to the group are found below

Here is my stunnel.conf

verify = 3 CAfile = /etc/stunnel/certs.pem cert = /etc/stunnel/stunnel.pem setuid = nobody setgid = nobody pid = /tmp/stunnel.pid debug = 7 output = /var/log/stunnel.log client = no compression = zlib [mysqls] accept = 3309 connect = 3306

I am using centOS and installed stunnel and openssl via the available rpms, using yum. zlib is installed as well, but i don't think this is a zlib issue, it seems like it just doesn't like "compression". Was compression added in a version later than 4.05? Am i missing something incredinbly simple?

Some output from the stunnel.log at high debug level
