Question work firewall blocks ssh traffic


Hi,

My home computer is a Linux desktop/server on which I store all my files, work etc. Until recently I used to connect to it in my lunch breaks from my fairly restricted win xp desktop. I have an ssh server running on it and was using putty on the windows machine to use vnc to work on it from work, access files, use programs that I could not install on my locked workstation.

Although the IT here barely know what ssh is they blocked the traffic recently(at least that what I deduced). I think this is done with an MS ISA server as I can not get an SSH connection to anywhere not just my home server. I tried running the ssh server on different ports but I still can not get through.

Can anyone recommend other secure ways to get access to my home computer(not telnet)?

Thanks

Have you tried running the server on port 443? This is the port used for https, and is unlikely to be blocked unless they don't want you visiting any secure websites.

I did and I had it running on other ports also. Thatīs why I think they are blocking the actual packets.

In this case, I suppose the firewall is blocking connections starting with the 3-byte SSH header. You could try using 'stunnel' to create a 2nd layer of SSL which would be indistinguishable from other SSL connections.
