1. psnxopr.slac.sstanford.edu (aka psnxserv01): for machine and beamline operators
2. psnxana.slac.stanford.edu (aka psnxserv02): for interactive data analysis
3. psnxserv.slac.stanfotrdstanford.edu (aka psnxserv03): for general purpose connections

The allocation of theses servers to the various activities is just to provide a low-tech load balancing and is not enforced.

After opening a connection to one of these servers , using your SLAC UNIX account, make sure to run in console mode: from the 'Custom session' dialog window, accept the default options (Application - Run the console, Options - Run the command in a floating window) by clicking Continue. 

For performance and reliability reasons we have disabled the ability to open a remote desktop (GNOME) on the NX servers. We plan to keep allowing only the console mode for the foreseeable future since the multiple GNOME sessions were taking too many resources on the NX servers. Let us know if you see any fundamental reason why the ability to open a remote desktop is required to do your job. 

This will open a remote terminal on your local desktop from which you can type the name of the application you want to launch. For example, you can type "xterm&" to open additional terminals or "emacs&" to open the emacs editor. Type "ssh psana" to connect to the interactive pool to do data analysis. When you disconnect and reconnect to NoMachine, these terminals and applications will remain in the state you left them in.

Note that the user will have to reconnect after running "pkill" and  and may have to try a number of times (possibly using the -9 option, as shown with the "kill" command command).
