Full Version: Simple Question
ThrillKill
yep is a simple question so am sure there is a basic answer to it but for the life of me i cant remember...anyways the company am working for has a internet block so users cant access the internet only the intranet.

basicly i wanna find a way to get access to the internet though there firewall or what ever they are using cos work is boring lol...currently looking in to http turnneling any methods would be fine

i'm in t he same boat wink.gif

i like to use shells personally! but you could just as easily set up an HTTP Tunneling proxy (depending on the firewall). use ssh or another secure daemon, i wouldn't suggest telnet!

whats the matter with irc? i am in luck to have a open port 80 mbut irc is closed. java applets or a simple webinterface doesn't work. whats up with irc tunneling?´

IRC is run on a blocked port range (for your firewall). The java applets are nothing more than regular clients. You will need to redirect your signal from port 80 to port 6667 (or whatever blocked port it happens to be). Like I said before, the easiest way around this is ssh or another shell client that is allowed through (you should have ports 23 and 22 open)... otherwise you will need to bounce your data off of another host who can redirect the ports... the most simple way to do this (that i know of) is to simply use netcat (or any other software that can write across networks) to redirect everything from port 80 to port 6667 and back again.

something like this might work (you would run this from your machine outside of the protected network) ->
CODE
nc -l -p 80 | nc irc.target_server.com 6667 | nc -b -l -p 80


then connect to your host on port 80 as you would the target server...

hope this helps smile.gif
