getting around a firewall?

[adam <adam@tao.ca>]

I have a little dilemma.  My work PC (windoze) is on a (gov't) network. 
The firewall blocks all ports save http, ftp, telnet, and maybe a few
others  -- ssh is most certainly blocked.   I want to be able to
securely connect to a remote server (Debian based) in shell.  I'm told
one way to do this is to tunnel ssh proxy through other port like http. 
What are other ways to achieve the end result?  I think I heard tell
that there is something in java that allows secure connections from
httpd (right from a web page).

thanks
