Here are step-by-step instructions for configuring a remote desktop connection with NoMachine NX client version 3.5 for data collection at MacCHESS.
(using Linux as an example)
Install the software. Download appropriate packages for your Linux distribution and install it. e.g. "yum localinstall nx*.rpm"
Session name: landline (arbitrary)
Host: landline.chess.cornell.edu Port: 22
Desktop type: Shadow
Select size: Custom 1600 1024 (The actual desktop size is 2560x1600. You will probably want the size of your window to be as large as possible while preserving the aspect ratio. Did I mention you should be doing this on a computer with a large display?)
Disable encryption: NO
Password: (get this from MacCHESS)
Session: landline (or whatever you named it above)
[Login] Available sessions: Local display...
