Is a paid version required to configure ssh?
Yes, on the server host you are connecting to. It does not matter which client is running on the device you are connecting from. The free NoMachine edition does not support connections by SSH. SSH is supported in any of the products of the Enterprise suite. Try Enterprise Desktop for example, which is like the Free Edition, but offers not just SSH support but also sessions from a Web browser, remote admin and more. Or, if you are connecting to Linux and are interested in running multiple Linux desktops on the same host, try one of the products from the Terminal Server family. They are all freely available to download and try as evaluation software.
What you might like to try is tunneling the NX protocol in a SSH connection. Pre-requisite is to have a SSH client on your client machine and a SSH server on your server machine. See the following article for more details.
Hi Victor and Leonick, would you be interested in trying a test library that we have prepared? It’s not a definitive fix, but it would help us for our investigations. We will send you a download link to the library and further instructions, we would basically need to know if there are any visible changes.
What macOS version are you connecting to?
You mentioned that permissions seem to be correct. Check in Accessibility, Screen Recording and Full Disk Access that NoMachine and nxnode (a component of NoMachine) have been correctly added in the Privacy panel? Remove and add again if necessary. This article shows the panels to check: https://kb.nomachine.com/AR11Q01061. Restart the nxserver. Does that help?
When you updated NoMachine, did you also update your Linux system?
When you say headless, do you mean ‘Headless Start’ rather than ‘Normal Start’ in Virtualbox? If you select ‘Normal Start’, do you get the same issue?
Please try adding this option in /usr/NX/etc/node.cfg
DisplayServerExtraOptions "-eventdelay 0"and try a new connection.
When executing the
--serveradd command, NoMachine verifies admin rights to access the CS by asking for a admin password. The next step is to add a public key, which gives it access to that host, assuming NoMachine is the admin of that host. By sending a public key as you mentioned, the admin verification is skipped, allowing you to add a node to the CS without requiring a sudo/admin password.No mean to specify IP address of the machine to add as a node, we have to be logged on it ?
Yes, the node will be connecting to the CS; we do not have a specific node address
“I can not log into Linux using default User name & Password”
You wrote Linux but you mean Windows, right? What error message are you seeing when you attempt to login?
Please check this article about accepted usernames and formats
https://kb.nomachine.com/AR03S01118What username are you using? Are you able to log in using the name of the account in short format (Local Account ‘username’ which you can see when going to C:\Users) and password?
Hi, there is no setting for what you are asking. With NoMachine, when a remote computer is a headless machine, we create a virtual display (an embedded X server). This display is not connected to the local input devices, so they can’t be used.
Hi, did you install as sudo? If not, uninstall, remove all traces of NoMachine, and then reinstall as sudo.
(https://kb.nomachine.com/DT07T00258#2.4)
sudo dpkg -r nomachine
sudo rm -rf /usr/NX/ /var/NX/ /etc/NX/
and install again:
sudo dpkg -i nomachine_8.14.2_1_amd64.deb
If he has sysadmin rights on nodes, no need to give him !M admin rights on nodes, isn’t it ?
Correct.
How to specify he is only administrator of a specified group of nodes ? We want him to be allowed to add, modify, remove nodes only on ECS for his group.
Having an “administrator of a group of machines (but not others)” is not currently supported in the CS design. We can evaluate opening a feature request.
Do you see something like the attached when trying to make changes? It is strange that you can’t quit the Player. What message appears, if any, when trying to quit the Player from the system tray?
I have edited permissions to the nxexec.exe
What exactly did you do?

Hi, can you tell us how you disabled HW acceleration on the client and server machines? Hardware encoding is disabled for the server in the server settings of the UI i.e the NoMachine server won’t perform encoding in the session. But hardware decoding is disabled in the session menu or in the player.cfg which is located on the machine you are connecting from. When you are connected to the desktop with NoMachine, open the menu (Ctrl-Alt-0) > Display > Change settings > Options, button Modify (https://kb.nomachine.com/DT09T00267#5.8), click the box next to ‘Disable client side hardware decoding’. Does that make any difference?
Hi, the logs need to be extracted from the server machine you are trying to connect to (they appear to be from the Player). The steps in the link I pasted need to be executed on that Linux host. Enable debug (steps 1-3) on the Linux server, go to your Windows machine (or another Linux), connect and reproduce the problem, gather the logs from the Linux host where you enabled debug.
Can you also tell us the desktop environment that is running on the problematic Linux host?
