Re: [Plug] telnetting around a firewall

["Nick R" <laktar@hotmail.com>]

Well a java applet would do something like that. The problem I see with 
httptunnel is that you have to be able to install and run software on the 
client computer. With a java applet a bidirectional data channel could be 
created that would require only the ability to run applets.

At the high school I go to, they've locked telnet out. That's why I want to 
get around it. They'll never find out and I don't think I'm technically 
breaking any rules if I do it w/ a java applet or something.
