OK, here it goes, albeit a rough version....
Here' what to do:
- Put the latest rugby.r and vnc-tunnel.r in one directory on client and
server.
- Start a vnc server on your desktop inside your corporate network.
- Start the vnc-tunnel.r in your rebol console on the viewing side. Type
vnc-client <enter>
- Start the vnc-tunnel script on the server side. Type vnc-server and enter
the ip-address with port 8002 and the http protocol when asked. Aka
http:/your-ip:8002
- Connect the vnc-viewer to the local port 5902.
And no it is not fast on the WAN althoug with tightvnc (www.tightvnc.com) it
may be better. With a bit of luck I'll turn this in to a generic
TCP-over-HTTP tunnel. The point this proves it the limited usefullness of
firewalls. ;-)
