When I try to connect, the server’s log file (see excerpt below) rattles off three separate users:
- u0138544 (Me, server-side account name)
- rob (Me, client-side account name)
- u0886896 (Defunct server-side account for departed employ who left before the server had it’s mother board replaced)
Why the other two attempt and why does this connect never get completed: client spins endlessly.
- The server (at work – Linux integrity 2.6.32-573.7.1.el6.x86_64 #1 SMP Centos 6.8):
- [root@integrity etc]# /usr/NX/bin/nxserver –version
- NoMachine – Version 5.1.54
- The client (at home – macBookPro)
- NoMachine – Version 5.1.54
[root@integrity etc]# tail -f /usr/NX/var/log/nxserver.log

Can you send to output of command: sudo /usr/NX/bin/nxserver –userlist to forum[at]nomachine[dot]com? Please also run debug, restart nxserver (
sudo /usr/NX/bin/nxserver –restart), collect logs and send them also that we could verify where is the problem. Instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT07M00098.2016-11-20 21:16:01 675.322 13556 NXNODE ERROR! Application terminated too early.
If you are able to reproduce this problem – can you send also file .xsession-errors? It’s in home directory. If you still have that log file from that issue, you can send the old one.
sudo /usr/NX/bin/nxserver –userlist

I can/have reproduce the problem over several nxserver –restart calls and will do so again (barring a miracle). Do you want the .xsession from the client or the server?

Attaching logs generated with debug level 7. It seems to be in a tight loop.
(I could not find a client side option to ‘not delete files’)@iceback submit logs to forum[at]nomachine[dot]com. They probably got rejected because they were too big.
Hi.
After enabling debug you need to restart nxserver (
sudo /usr/NX/bin/nxserver --restart). After that please reproduce problem tar full log directory (cd /usr/NX/var && sudo tar zcf serverlogs.tar.gz log/) and send file to forum[at]nomachine[dot]com.Is it headless machine?
To get rid of warnings with defunct user accounts, please delete them from NoMachine database:
(`sudo /usr/NX/bin/nxserver –userdel rob &&
sudo /usr/NX/bin/nxserver –userdel u0886896 `).This machine has a KVM attached so it should not be (and in the past wasn’t) headless. Currently x is not starting and am looking in to that as well.
/usr/NX/bin/nxserver –restart

NX> 162 WARNING: Cannot find X servers running on this machine.

NX> 161 Enabled service: nxd.The issue has been resolved by fixing the xdm initialization. I believe that is a remnant issue in what NX is doing in absence of a GUI – claiming it will start an virtual session, then failing to do so – but that’s for another day.
The heart of the issue is a fault in ‘prefdm’ script: it does an rpm query for packages which supply a graphical interface, then iterates over the results. The configuration of the server in question had at some point in the recent past (last OS update?) lost it’s X packages and the query return “no packages found for graphical interface” but the prefdm script never recognized the error and tried to process each of those words as a possible display manager! And did so repeatedly.
Re-installing the 500+ packages involved in X did the trick.
