[K12OSN] Squid Question

[Ken Johnson]

I need to filter Internet access for a k12LTSP network in a church youth center.

I have a few questions. I am looking at Censornet, SquidGaurd and
DansGuardian. I have never used any of these before.

1) Does the proxy run on a separate machine, or should it run on the
k12LTSP server?

2) Can someone point me to some step by step installation instructions?

3) What are some pros and cons of each?

4) Are any of these filters really effective  (after all its a church).

Thank you
