Annoying isn't it!

Took about 15 mins to setup and test, and has since worked flawlessly.

Yeah, the way it works is I run the HTS (http tunnel server) on my home box,
and then the HTC (client) on my laptop.  On my laptop I then ssh to localhost
using whatever port I set in HTC and it "magically" sends it to the port I set
in HTS on the server (so 22 for ssh).  My laptop runs XP, but there are linux
clients.

This is the .bat file I use on my laptop to connect

c:\temp\httptunnel\htc -F 8888 -P <schoolProxy>:8080 <homeHostname>:8888
putty -load "httptunnel"

and this is the script I run on my home server to start it
/usr/bin/hts -F localhost:22 8888


All of this traffic goes via the county proxy server by the way, and it works
fine.  You can only have one connection per instance of hts, but you can have
multiple hts setups running on the server listening on different ports.  The
HTS process needs restarting sometimes if the session got interupted (shoddy
school net connection mainly!) but as I said, I've got a page on my server
which just restarts it for me.
