Systemctl nxserver.service

[dande74]

Hi,

On one of my servers after upgrading to 7.4.1 I cannot connect. Getting the Ooops!

When I’m looking at the status of nxserver.service I see only the following:

[userl@server ~]$ systemctl status nxserver.service
● nxserver.service - NoMachine Server daemon
     Loaded: loaded (/usr/lib/systemd/system/nxserver.service; enabled; vendor preset: disabled)
     Active: active (running) since Tue 2021-04-06 20:52:25 CEST; 31s ago
   Main PID: 364052 (nxserver.bin)

     Memory: 115.7M
     CGroup: /system.slice/nxserver.service
             └─364052 /usr/NX/bin/nxserver.bin --daemon

On another server where I haven’t upgraded yet, running 7.3.2 it looks like this:

[user@server2 ~]$ systemctl status nxserver.service
● nxserver.service - NoMachine Server daemon
     Loaded: loaded (/usr/lib/systemd/system/nxserver.service; enabled; vendor preset: disabled)

             ├─763471 /usr/NX/bin/nxcodec.bin
             └─763696 /usr/NX/bin/nxplayer.bin

One thing is that I’m afraid I was out of disk space when upgrading. I tried to uninstall the install again but it didn’t help.

Any ideas?

Kind Regards,

Based on the command output it looks some of NoMachine service are not running. you can confirm it by running command
sudo /etc/NX/nxserver --status

To be able to debug specific problem we would need to collect debug logs. You can enable them by:

sudo /etc/NX/nxserver --debug --enable all 
sudo /etc/NX/nxserver --restart

Reproduce the problem.

sudo /etc/NX/nxserver --debug --collect 
sudo /etc/NX/nxserver --debug --disable all

Please attach logs to your reply here or you can send them to forum[at]nomachine[dot]com making sure to use the topic’s title in the subject.

Unfortunately, that folder where empty. But, when I restarted like you suggested..

$ sudo /etc/NX/nxserver --restart
NX> 162 Disabled service: nxserver.
NX> 162 Service: nxnode already disabled.
NX> 162 Service: nxd already disabled.

NX> 161 Enabled service: nxd.

..I can start a session using the client.

But starting/restarting using systemd makes the nxserver not working.

It looks for me from the nxserver –restart command that NoMachine does not detect physical desktop on that host. Can you tell me your OS and Desktop environment you have on that host?

[dande74]

Manjaro Cinnamon

uname -a
Linux host 5.11.6-1-MANJARO

systemctl get-default
multi-user.target

Hi,

We tried the same OS and had no problems neither with the detection of the desktop nor with the start of the nxserver service with systemctl. Maybe as you said installation was broken during the update and your disk was out of space? Please try to uninstall the program (sudo /usr/NX/scripts/setup/nxserver --uninstall && sudo rm -rf /usr/NX /etc/NX) and install again the newest version.

Hi,

That didn’t make any difference.

I see differences when starting using systems or nxserver

systemd

     CGroup: /system.slice/nxserver.service
├─33087 /usr/NX/bin/nxserver.bin --daemon
├─33193 /usr/NX/bin/nxexec --node --user daniel --priority realtime --mode 0 --pid 46
├─33198 /usr/NX/bin/nxnode.bin
└─33220 /usr/NX/bin/nxclient.bin --monitor --pid 4273

nxserver

     CGroup: /system.slice/nxserver.service
├─33549 /usr/NX/bin/nxserver.bin --daemon
├─33593 /usr/NX/bin/nxexec --node --user daniel --priority realtime --mode 0 --pid 46

Hi dande74,

Not sure what could be the matter with your installation. We have tried NoMachine on our own installation of Manjaro and were not able to reproduce it. Manjaro is Arch-based which is not in the list of officially supported distros by NoMachine although we do test with a large variety of distros and desktop variations in their factory settings.
