The client could be disabled by replacing the file ‘/usr/NX/bin/nxplayer.bin’ with a script doing only this:
#!/bin/sh
exit 255
The old file can be renamed and have permissions that don’t allow users to execute it.
This change will affect the NoMachine tray menu because
a) the menu items related to session starting will no longer work
b) the configuration of the server/node with the ‘Server preferences’ dialog will no longer apply the changes
Note that at every software update you will need to carry out this operation.We’ll see how disabling of the client can be made better.
