Just to follow up on my earlier posting, it seems like others also have this problem – identical authentication failure messages: see other thread here
I’m now stuck in limbo, as I can’t shut down the service, nor can I remove NoMachine as I am unable to stop the service. This is completely unacceptable as I do not want my laptop to offer a NoMachine service on the network that I can’t shutdown.
Please can you offer some advice on how to shutdown the service so I can remove NoMachine.
FYI we have a paid for Linux Terminal Server Edition that I am now unable to use (because of this security risk).
Best wishes,
Jon
