I would like to set up a remote desktop system similar to PC Anywhere. I currently have SSH usable with Putty, but I would also like to setup something graphical as well.

The server, or host, is at home running Debian Sarge with a permanent Internet connection with a dynamic IP and three layered firewalls that I can control.

The client, or remote, is at work running WinXP on an ISDN data line with a static IP. It is behind two firewalls, one of which I cannot control.

Thus, any connection must be outbound from work to home. I also have a dynamic DNS service, so I can always find my home IP.

I currently have IP filtering set up using iptables so that any ports that are open are only open to the fixed IP here at work. Everyone else sees them as filtered.

What software on the WinXP machine can I use? (preferably free) What else do I need to setup? Which port will I need to forward? I'm just not sure on where to go from here.

Thank you for your time.

or...

Alternatively, if I were to do this with Linux, how would I setup xdm?

Would the /etc/X11/xdm/xdm-conf file contain: :1 XHome foreign my.home.ip.net :1 ?

I have used for this cygwin + x.cygwin - you get both small UNIX like environment and X server.

Firewalls are not problem - if you connect with ssh you can run it with X forwarding. (There is such option in PuTTY)

If you will run X in cygwin you just run "ssh -Y ..." for X forwarding.

I for simple purposes x.cygwin is more then enough.
