I've used squid to do it. Squid is great, but content filters, in general, suck. For squid, you can use squidblock: http://www.hklc.com/squidblock/ And the slightly more intelignet squidguard http://www.squidgaurd.org But I have to agree with Scott. There is no better content filter than human eyes. If you don't have time to supervise children's net usage, turn off the computer. -- Andrew S.
