[squid-users] Forcing all user to go through proxy server

Hi,

I was toiling with the idea of logging all users in order to get statistics
on where they are going on the net and how long the are using the system,
etc. I was then introduced to 'SARG' which is doing exactly what I wanted.
Thanks to Bruno Guerreiro who gave me a push in the right direction.

My problem now it that I have noticed that not all activities are logged
in 'access.log'. This includes ftp downloads/uploads, telnet sessions
etc. In particular, some users on my local area network are NOT logged.

Now I have two questions:

1. How do I force everyone (every PC) on the LAN to use the proxy server? I
need to log all activities on the LAN.

2. How do I force all requests, eg ftp, telnet, http, etc. to get logged?

Fred.
