Nothing can be easier.
You will have to recompile your kernel to be able to forward all traffic of=
=20
your employees to squid, even if they don't use proxy in their browser.=20
Compile it with Options IPFIREWALL_FORWARD
Then install squid and add a rule to a firewall like this:=20
fwd 192.168.1.1,3128 tcp from any to any dst-port 80 via xl0
Where 192.168.1.1 is a router, 3128 - squid port and xl0 is an outer=20
interface.
This will make all your network users go through squid and all their moves=
=20
will be recorded. You will just need to install SARG, which will draw nice=
=20
HTML tables with IPs and sites visited by them.

I use it myself and it works just fine. I also use squid to deny downloadin=
g=20
of avi and mpeg files, and also to deny some sites that are not work-relate=
d=20
and should not be visited from office.

Also Squid and SARG can count traffic, so you can see who spends how much, =
if=20
you don' have an unlimited internet.
