Xboard and a remote engine I want to analyse chess games with xboard and stockfish. Locally this is no problem.
But my PC is slow, so I have rented a faster linux server, and I want let stockfish run on it.
How can I use xboard on my PC, to connect to stockfish running on the linux server?
I have tried on the command line:
1) ssh -p &lt;port&gt; &lt;user&gt;@&lt;host&gt; /usr/games/stockfish

This works. But:
2) xboard -fcp &quot;ssh -p &lt;port&gt; &lt;user&gt;@&lt;host&gt; /usr/games/stockfish&quot; -fUCI

does not work. There is a connection to stockfish on the server, xboard gives the correct version of the engine, but as soon as I enter the first move, it terminates with error of &quot;broken pipe.&quot;
You need to connect to your server with ssh -X command to enable X forwarding. The details of how this needs to be configured can be found in this answer on
Unix and Linux Stack Exchange.
