Hello,
I run NoMachine in my home LAN to communicate between two PC’s, both running Linux. The connection runs flawlessly over my LAN. However, NoMachine popped up a message requesting to update the software, and after starting this, it asks for my administrative password. That password has never changed and is the exact same one I used when I installed the NoMachine server and client.
This is the result of sudo -l:
root@KerryPC:/usr/NX/var/log# sudo -l

What steps can I take to resolve this and achieve successful password authentication that will satisfy your update script?
Many thanks for your help!Can you send us the whole server-side folder $HOME/.nx ? Please zip up the file and send to forum[at]nomachine[dot]com using the title of your topic as the subject. Thanks!
Hello johngalt17.
Those logs are insufficient to determine the nature of the problem. Please run the interface to change settings on your server, select “Player settings”, “Security”: in that pane check the box “Don’t delete log files on exit”.
Then reproduce the problem, collect the complete log on the server by command
sudo /etc/NX/nxserver --debug --collect.I have had exactly the same problem for about six months, first on Fedora31, and even now after upgrade to Fedora33. I am running the free version. Right now I am on the verge of throwing out NoMachine altogether, but I’ll give it another chance. Everything I have tried has failed, and googling the problem brings on useful results.
What I don’t understand is why you want logs from the server side, when what we have clearly is a software update problem on the client side. At the moment I don’t even have a server, since I upgraded my it and deemed it useless to re-install NoMachine there until this problem is solved.
Another question is what you mean with “a user with administrative rights”? Is it enough with a user with passwordless sudo access (me), or does it have to be root? I did of course try both, with no success.
Anyway, here is some info about my environment, and I also attach some logs that you may find useful.

lmcjomaHi lmcjoma,
The log files failed to attach, maybe because they are too big.
“What I don’t understand is why you want logs from the server side, when what we have clearly is a software update problem on the client side.”
Provided the issue is on the client-side, then it would be useful if you could send us client-side logs. Please see the following article for guidance: Collect server and client logs manually.
Can you please send them directly to forum[at]nomachine[dot]com making sure you use the title of the topic in the subject of your email? Thanks!
Hi lmcjoma,
we would like to send you a test program. Would you mind running that program in order to collect more debug logs?
Please let us know and we will send it via email.
Thanks!Hi lmcjoma,
We understand your concern. The program is a binary, however it is just a modified version of the nxexec binary, so it should not represent an issue. The procedure will be to simply replace the original nxexec with the test one, reproduce the problem and collect logs.
Let us know if this would be ok for you and we will send you the test program via email.
