Hi all I am currently in a 9-5 where almost all non-web outgoing traffic is blocked. So I have a dedicated and I want to run httptunnel on it so I can ssh to my servers etc. I am not sure how to find out exactly which ports they have blocked on their firewall, and thus which I have to play with. Obvs port 80 is OK but I can't run httptunnel on port 80 because Apache is using it. I know I could buy a VPS and run the proxy on port 80, but don't quite have the cash for this atm. Are there any tools I can get that show which ports I can access? Cheers!
