I have a cache/filter box running Squid, squidGuard and DansGuardian. My
LTSP server is running identd. I do the following to monitor web

tail -f /var/log/dansguardian/access.log

I also wrote a Perl script to monitor Google searches. 

The only problem I've run into is that identd on the LTSP box was
hogging the CPU when there was lots of surfing happening at once.
However, this problem *seems* to not be as bad since I moved the
cache/filter server to a much more powerful machine.

Which filter are you using?
