Hi Darac,

Yep, this solved indeed. First I tried and got an error. I thought it
would be because of the fact there is no x-server. But it was just the
case of editing sshd_conf and allow port forward.

Great! Thanks. One to go.

I apt-get-installed screen and Ctrl-A-D worked as a charm.

The real mystery now is how to run xboard! :)

Just to clarify, I think you meant:

fox$ xboard -ics Flik # Fox connects to Flik server the same way other
players (netizens) do.

Flik is the ICS (internet chess server, or xboard server), not a client.


Thanks!
