Packet tracking

Hello,
I recently set up a network where I have several win95 machines being masqueraded behind a linux box router/firewall. Whell there isn't a firewall installed. i just turned off all the services and have packet filering in place.
My question is, is there a way to keep track of what the users are doing? See, big brither wants to make sure that the eomployees are not abusing their privileges on the net by wasting time on some IRC port, or browsing web sites that they shoudn't be watching. Or playing net doom etc.
I know that FWTK has this feature but I don't think I want to try to install the a firewall. I don;t really need it!
As the system is now, you can't log into the fireewall unless you are at the keyboard plugged into the box itself. And since the intranet si using 192.168 class, there really isn't a way an outsider could access them... Right?
Thanks for your help
Marcelo

Well, you can add the -o option to the end of some of your firewall rules, which will cause packets matching those rules to be logged via syslog, but this has a few disadvantages. It it pretty inflexible, so if you wanted to log traffic to 10 different IP's, you'd need 10 firewall rules :-(. It also logs a message for each packet, so be prepared for very large log files indeed. To make use of the information, you'd probably need a Perl script of something to filter out the garbage, and give you sensible information.

If you want something better, you could go to:-

and pick up the Sniffit package. This will do logging if you set it up right, and does loads of other things to. You may want to keep this away from your users - its potential for abuse is almost unlimited....
