Re: [Plug] telnetting around a firewall

[adam <adam@looney.com>]

I don't see how a java applet would help.
you are still coming from behind the firewall...
I think you need something like this
http://freshmeat.net/appindex/1999/02/19/919455167.html
httptunnel
 
  httptunnel creates a bidirectional data channel through an
HTTP         proxy, from your isolated computer behind a restrictive
firewall, to    a system on the Internet you have access to.

of course, you use something like this at your own risk.  Did you just
ask what the policy on telnet at your org is?
