Setting up a game between two computers I was hoping that this would be a simple exercise but I have spent the last two days looking into this and can not find an answer (easy or otherwise). What I want to do is have my iMac play my ubuntu laptop in chess over a lan. 

I know I can do this by manually entering the moves but my hope was to automate the process. And eventually play many games alternating parameter such and length of time per move etc.   

Has any one done this or any ideas on how to achieve this?

P.S If this has been answered before I apologise.
Get Arena!

Setup Arena on your iMac and Ubuntu computer. Register a computer account for each computer on a server of your choice. Of course, both computers need to login on the same server. Let one computer request a match and let the other computer accept the match.

That's it.

Arena is pretty cool. It wouldn't surprise me if you could create a script to automate a bunch of stuff you would want to do.
