You can try the new line sequence “\n”, for example:
NodeLoginGreeting “Hello\nWelcome to your NoMachine session\nHow are you today?”
Also, it would be preferable for this message to be displayed *before* someone logs into a NoMachine session. Is that possible?
Check node.cfg key: UserScriptBeforeSessionReconnect. More info about user scripts you can find there: https://knowledgebase.nomachine.com/AR02L00787
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.
Is the local connection still working? If it’s not a problem with the credentials maybe try to unselect “Use UDP communication for multimedia data” (it’s in the player – in connection file) in case UDP ports are blocked in the router.
Logs from both the client and server side would be helpful to investigate the problem. You can send them to forum[at]nomachine[dot]com, making sure you add the title of the topic as the email subject. Instructions about debugging and collecting logs can be found here: https://www.nomachine.com/DT11R00181.
If your router doesn’t support UPnP, External IP won’t show in the nxserver command output or nxplayer GUI. Please try port forwarding (which you already configured). Reverse all UPnP changes you made in server.cfg and make sure if the chosen port is not being used by another service. To connect you need to open a new connection in the nxplayer, enter your Public IP and use forwarded port (in your case 21960).
We cannot reproduce such a problem on Ubuntu with Mate. Are you able to take a look if the problem isn’t shown also on that machine, on the physical monitor? Maybe it’s headless?
Could you please check if the problem happens when you disable the X server and restart nxserver (check also if
DefaultDesktopCommand mate-sessionis set in
You can find more information about problems on headless machines here: How to solve black screen and other possible problems on headless machines.
It looks that your BT hub is in NAT mode and the desktop PC is not in the network broadcast by this device. To be able to connect to machines in that mode you need defined manual forwarding rules. To avoid that set BT hub to Bridged mode. Then both devices will be in the same subnet.
Do you have access to that machine (for example through ssh)? Is there plugged monitor? Please try to stop X server (
sudo init 3) and restart nxserver (
sudo /etc/NX/nxserver --restart). More about problems with headless machines you can find there: https://www.nomachine.com/AR03P00973March 16, 2021 at 16:55 in reply to: No printer access for NoMachine Linux 7.1.3 on Centos Stream? #32426
It’s a known issue. A fix should be ready the next available release. Thanks for taking the time to report.February 22, 2021 at 11:36 in reply to: “No available sessions” on Linux server (Debian Buster) #32093
It looks that there is a problem with the pam_mount module when creating sessions. Please refer to this article: How to solve hanging problems when creating a NoMachine session (pam_mount module is in use)February 17, 2021 at 15:27 in reply to: NoMachine time lag after remote computer inactivity/lock screen #32010
Are you sure it isn’t a system problem? Can you check the CPU usage when the problem is happening?February 17, 2021 at 14:30 in reply to: “No available sessions” on Linux server (Debian Buster) #32009
Did you reinstall NoMachine? We are aware of a similar problem. Please take a look at this Trouble Report: Problem uninstalling a version 7 and then installing version 7.1.3.
If this is your case, please use the described workaround.February 17, 2021 at 09:51 in reply to: NoMachine is not connecting to Ubuntu after reboot #31996
We weren’t able to reproduce the problem. Can you please tell us more about the issue? What error does it show? Are there nx processes after reboot (
ps aux|grep nx)? Are connections possible after manual nxserver start (
sudo /usr/NX/bin/nxserver --startup)?February 16, 2021 at 16:10 in reply to: Manjaro/Arch Linux (2021): NoMachine does not start X server/no display #31983

Do you have Desktop Environment (DE) installed on that debian? Is it headless? There is article with instructions how to install some GUI on linux: https://www.nomachine.com/AR04K00667#4.
If it’s headless after DE installation, please set adequate DefaultDesktopCommand in /usr/NX/etc/node.cfg (take a look on point 2.1 in mentioned article) and restart nxserver (
sudo /usr/NX/bin/nxserver --restart). Then you should be able to connect.
