I'm trying to SSH to my dedicated server (Ubuntu 12.04 LTS) from my school and the connect ends abruptly with this error:

I've tried connecting to other servers, changing the ports, changing compression, but nothing changes. I have the LogLevel of the SSH Daemon on my server running on full alert but nothing has been logged pertaining to these connection attempts.
My school blocks all applications besides Java jar files (I use Mindterm as my SSH client). I believe my school uses some form of the [URL="http://www.iboss.com/"]iBoss Network Security Suite[/URL] as a firewall (which is probably scrambling the packet or something) and I know for a fact all the computers are managed by [URL="http://www.jamfsoftware.com/"]JAMF Software[/URL] (digging around in system log files).
Other people have had this exact problem as well:

Those iBoss hardware appliances block/mangle SSH packets.
The only two ways I know to circumvent that is to tunnel SSH traffic through HTTPS over port 443, or to use Windows RDP to just remote control the remote host.
My school blocks use of HTTPS as well, so fantastic.

Quick question, when you tunneled your connection did you have access to a shell?
