Meh. I'm not the lan nazi, however I find amusement in getting around the firewalls at both uni and work *lol* The university one I've pretty much gotten around completely by forwarding a port on the Linux server to my home firewall and using that to view webpages (blocks their filters completely then ), and as for work... I have Trillian working through the firewall, but that's about it.
yeah most messenger type progs will get through these days because they've changed the packets to look just like http port 80 traffic, and as such, indefinetly find it's way around firewalls and filters.
raveng - there is a difference in "getting around" a University network and a Department of Defense network . I can assure you the DOD computer system is far more locked down than your school and all the traffic is ACTIVELY monitored (there is no right to privacy on DOD computer systems) .. And the punishement for "getting around" is also FAR more severe than anything the school would give out.
