I was trying to solve a problem with an application on the Z not talking to the outside world, so I investigated the /proc/net/nf_conntrack file on my linux gateway/firewall, and hacked up a quick perl script to make that file more user-friendly. I've been thinking about doing this for quite some time, so I wrote it up and posted the script. I hope someone else finds it useful too!
