How to enable compression? (`-z` doesn't seem to work)

I've compiled the latest master branch, and I've tried specifying -z on both ends (client and server), only client, only server, and the connection just seems to reset.

Without -z I can make ctunnel work properly.

The compression code is a bit broken ( my opinion ). I have a fork which works ( at least for me ).

@thaughbaer, have you considered submitting a PR? I have also run into problems with the compression not working, and that was the only thing I actually wanted out of this library

Wow @thaughbaer, crazy coincidence: I was also looking into using ctunnel specifically for compressing traffic to/from DB2 to improve performance over a WAN. I'm happy to see that your fork specifically addresses this scenario.

@aceberle you should find it works well with Db2. I've only used it on one project but there were terabytes of data involved across many connections. I don't use and haven't tested the VPN mode. I was using Db2 going from AIX to Linux from ground to cloud on an unencrypted ( Db2 ) connection. Compression ratios were around 10:1 with around the same improvement in query time. Ping me with any issues.
