Chapter 3. Remote connections
It is possible to play the game over a network connection with another
computer. To do so both players on both computers have to select one
color played by the local player and the other by the remote player. Who
chooses which side does not matter. It even does not matter if both
choose to play the same player as this will automatically be
interchanged by the game.
One of the computers will act as game server. Only this one can start a
new network game. Also all its game data will be transfered to the
client computer. You can force your computer to be server if you do not
supply a hostname in the network dialog. This dialog pops up if you
start a new network game. As a client you enter the hostname of the
machine on which the server is running. The port does not usually need to be
changed, but you can enter any valid port number there.
