Hello,
in case of limits per user, questions are for kernel and operating systems. NX user and any other users are under kernel control. I think processes
are not simply counted as they can have many threads, and every thread is counted as well.Resource limit is controlled by kernel, so when you have issue try to find which process has a lot of files in use, which one has a lot of threads etc
There are system tools which can help as lsof or ps.We have a guide available at:
https://www.nomachine.com/AR04O00927which contains for example answers for your question regarding where limits are set for user nx if not in limits.conf
[…]
Systemd limits are set in the following files:
/etc/systemd/system.conf
/etc/systemd/user.conf
[…]For default configuration file, during installation, setup is checking what kind of system it is, what tools are available among those required etc so there is no one default config key.
If you need clear one, uninstall nx, remove .cfg and install again.Hello Jeremy,
im not sure, but maybe its enough to set limit for virtual sessions?
Its available to set in server configuration file:#
# Set the maximum number of concurrent virtual desktops.
#
#VirtualDesktopsLimit 20file: /usr/NX/etc/server.cfg
set:VirtualDesktopsLimit 1
Hello, I think it’s not possible. Connection owner has always rights to his own connection – and it’s important as a network connection can be interrupted.
It seems like you are looking for a ‘guest’ feature which is already available. That way every connection is assigned to different user and the same nxplayer will be able to recognize sessions started by a specific ‘guest’.
Hello,
Every session requires a set of free ports which are calculated based on DISPLAY. Increasing the display limit should increase the pool available and can avoid such problems as the on you are describing. Please, edit server.cfg (/usr/NX/etc) and set value for DisplayLimit key.No nxserver’s restart is required. New connections will use new value.
For example:
#
# Set the maximum number of displays reserved for NX sessions.
#
DisplayLimit 400If such value as 400 is not enough, and there are still problems, maybe it’s worth checking what ports are in use and change the display range. Another useful key is DisplayBase.
Hello,
please increase display limit in server configuration file. No nxserver’s restart is required. New connections should work just after save new value in server.cfg.
For example:#
# Set the maximum number of displays reserved for NX sessions.
#
DisplayLimit 400Hello Zardoc,
you send logs of nxclient – .nx from userhome which is not enough to find a reason of problem appearing on your host,
please send to us logs of nxserver of the affected computer, the procedure and paths are here:https://www.nomachine.com/DT10O00163

[…]Hello,
it should be noted that this ‘create display’ feature should be intended as a fallback for those cases when it is not possible to detect a graphical session running on the server.
Having a Desktop Manager installed and running correctly should make this fallback unnecessary.As for the “Always create a new display on this server” checkbox, we agreed that such choice should be remembered on client side (and for the specific user) without causing any modification
of the cfg file on the server. Related FR: https://www.nomachine.com/FR09R04022Hello,
there is an article about that kind of problem:https://www.nomachine.com/AR08N00898
How to solve ‘session negotiation failed, application terminated prematurely’If you’re still having issues, install ‘xterm’ and run it as desktop command (instead of gnome-session).

Hello,
there is also in node configuration file
/usr/NX/etc/node.cfg
a key:#
# Specify hostname for the NoMachine node.
#
NodeName testnameplease set here something short and it will be used instead of long domain name.

Hello,
this seems to be SSH limitation rather then NX, anyway You can change #UserNXDirectoryPath in node configuration file and this way shorten path a little.
Hello Aubert,
there is article explaining what ‘disabled nxnode service’ means:https://www.nomachine.com/AR07Q01037
When is the nxnode service disabled on Linux?I hope it helps

Hello,
the url to download recent package has been changed, now it is:https://www.nomachine.com/free/linux/64/deb
Replaced ‘download’ by ‘www’. So, full command now is:
wget https://www.nomachine.com/free/linux/64/deb -O nomachine.deb
Hello,
seems that are some problems with correct handling of the Fedora 32 Login Window.The workaround should be to set in /usr/NX/etc/server.cfg:
PhysicalDesktopAuthorization 0It disables asking for access to the desktop, so use only if there is no other user on that host which should access the desktop.
And the second thing is that switch doesn’t work correctly after login/logout to desktop
so you need to disconnect and connect again.Hello,
yes it should work without additional methods.Can you please enable debug on server side, restart nxserver then reproduce issue, collect logs and send as mail attachment to address forum (at) nomachine.com with title
“password-required-for-private-key-connection”Detailed instructions about collecting logs on both side(client and server)
are available here:
https://www.nomachine.com/AR10K00697 (for server side logs)
and https://www.nomachine.com/DT10O00163#2 (client side).Regards
