I don't know of anything ready-made, just some general steps that could be used. For a good experience you would probably need to change the setup to non-static IPs (and use dyndns.org or something similar to overcome the dynamic IP of the modem). But to get it working on dynamic, through router etc.: You could rely on reverse SSH tunnelling. You then need somebody on the inside to initiate the link (possibly a script that they can run locally when they need assistance), and a static IP on the other side (US). See "man ssh", under the -R switch, and do some searching on ssh reverse tunnelling as well. So on A (haiti) you run: ssh -R 22:localhost:2022 -l myusername B_ip and for as the long as the link is up, you can, sitting at B, do ssh -p 2022 localhost ...to login via SSH on A. That gives you shell access. To get graphical access, you then need to set up some desktop remoting technology over the reverse SSH link - either NX/FreeNX or VNC (I think VNC is easier to set up). // Dag Sverre ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
