Um... seems to me that if you only want students to have access to the www thru the squid proxy, then the best setup would be to have nothing providing internet access to the student machines at all, only provide them with the proxy. Then only the proxy machine needs access to the internet. ie. the student machines see the proxy, but only the proxy sees the internet. Seems like a bad idea to just go blocking port 80 'cos that's what most webservers use. Students will get around that pretty quick :)
Of course, I could be completely on the wrong track here, apologies if I am. I don't know much about your specific situation, so it's possible I've missed the boat entirely ;-) Cheers, Gareth On Monday 15 September 2003 17:48, Terry Cole wrote: > RH 9, running squid and Dan's Guardian. > How to block port 80? > > Students are bypassing squid and getting strait out to the net. > > IPchains was set up originally, but has lost it settings and know does > not want to work. > > Cheers > > > Terry Cole > Rotorua, New Zealand > mailto:[EMAIL PROTECTED] > mailto:[EMAIL PROTECTED] > http://www.cole.gen.nz > http://www.websnz.com
