This info is available at the NoMachine site too, but Mac OS X is not mentioned explicitly (you just have to input the right keywords into Google to find it). For Mac OS X one has to substitute the Command key for the Alt key in the official NoMachine shortcut list.

Reference for the nxserver and nxnode command line utilities.

I've built my own nxclient start scripts for use with LTSP5 (Ubuntu) based on the startx script that is shipped with LTSP. The scripts assume that they are placed in /etc/ltsp/screen.d and they take use of my small fix-focus utility too.

I bet you've already noticed the focusing issue with nxclient if you tried to use it in rootless mode, just by running with xinit. The problem occurs when you disconnect from the NX server and start nxclient again: the client does not get the keyboard focus no matter what.

You can freely download an NX client for Mac OS X from NoMachine's website. However this client is not fully compatible with the FreeNX package (which is actually based on the same sources as NoMachine's NX server). You can successfully connect to a FreeNX server, but the keypresses are not transferred correctly (some garbage comes out on the FreeNX server instead of what you really pressed). I've found a workaround however it is a bit cumbersome:

1. start clean, so neither the NX Client, nor X11 should be running
2. start the NX Client, set up a session and start the connection (the NX Client will start X11)
3. after a successful connection suspend the session (press the "x" in the top left corner of the window), but keep X11 running (this is important!)
4. now reconnect to the suspended session and this time the keys will work correctly

This works both with the U.S. and with the Hungarian keyboard layout.

If you've eg. Xubuntu on your server with Xfce as the default desktop environment, then it's not trivial how you can connect with FreeNX and use this desktop environment. In the nxclient enter the session configuration screen, set the "desktop" to "Unix" and "Custom", enter "Settings" and choose the "Run the following command" for the "Application", and enter this into the textbox: /usr/bin/xfce4-session. In the "Options" select the "New virtual desktop". Press OK and select in the "Display" section "Full screen". Now you're all set.
