I'm trying to get an SSH/SFTP connection going out of my school. Unfortunately, all web traffic goes through a filtering proxy. (twotrees.com) I run a website for one of my classes and I would really like to have shell access to the server(and my home server too). As far as I've seen, nothing except ports 80 and 443 go through. So, the first thing I tried was to move my SSH server to port 443, and tell PUTTY to use the filtering proxy. However, they also filter the protocol I guess, since that didn't work either. I've Googled a bit, but I couldn't find anything that doesn't involve installing something - which I can't do since it's a school computer. So I'm at a loss. How could I make SSH look like HTTP(s) on port 80/443?
