Connecting logs me out

[Tom Bradford]

I’ve NoMachine working perfectly well on my little local network comprising two machines running Mint 20.02 and a Raspberry Pi running Raspian.

I’ve just installed NoMachine on a fourth machine running Mint 20.03.  When I initiate NoMachine on this system it correctly identifies the other local machines available to connect to, but if I click on one to create a connection I get logged out of my current session and presented with the Mint logon screen.  When I do so there is no NoMachine instance running on the desktop.

I can connect to the machine and have a running NoMachine session onto it, but cannot set up a connection out of it even to the same machine.

I dare say a look at a log would help but have no idea which one you’d want to see.  Let me know and I’ll put it up here.

Answering the queries below:

Both machines are running NoMachine v 7.9.2. Linux

Both are physical machines on a 192.168.20.0/24 network

The remote is running Mint 20.2, the local Mint 20.3

The remote has the Cinnamon 5.0.7 desktop, the local MATE 1.26.0

Anyone have any ideas?

Hi, just so I understand correctly. On your fourth machine running Mint 20.03 you can connect to it from another Player, so as a “server” it is working correctly?

But, when you want to connect from it to another computer (including localhost), you can’t?

 

I get logged out of my current session and presented with the Mint logon screen.

It’s this sentence which is confusing me 🙂 Is this referring to the Mint host as a Player or a Server?

Yes, I could NoMachine into the ‘problem’ one, but if I sat at the problem one and hit the NoMachine icon in the Panel it would bring up the NoMachine page correctly identifying the other machines available.  However if I selected any of them and clicked on the ‘connect’ button the display would blank out and a few seconds later the Mint log-on screen would come up just as if I’d rebooted.

However the matter is now moot.  On Monday I couldn’t boot into Mint at all – the logon page was totally unresponsive to the keyboard although the mouse worked so I scrapped the Linux installation and installed Windows 10 instead, and NoMachine is behaving perfectly well on that.  So I suspect there was some underlying fault with the Mint installation NoMachine was calling.  However we’ll never know.

Thanks for letting us know.

It’s quite possible that it was something to do with the Mint installation as it seemed to be affecting just that machine; your other 2 Mint machines were ok. We use Mint a lot in our labs, as many version combinations as possible, and have not seen this.

Anyway, I’m glad you’ve fixed it, albeit in a drastic way! 😀 Keep nomachining!
