Can only connect from login screen on workstation

[rainingwaffles]

Using NoMachine 6.5.6 from a Mac laptop to my CentOS 7 workstation, running NoMachine Server 6.5.6 allows me to connect to the login screen and even control the session, but if I close my NoMachine session and try to reopen it, or try to initialize it anytime I’m already logged in then it doesn’t connect correctly.  That’s to say it “connects” but the Xsession itself isn’t displayed.  The window says, “<No available sessions on this server>”.

The nxserver.log seems to complaining about permissions issues in my home directory.  Could the accounts be configured incorrectly?

Debug logs from Linux server with debugging attached here.  Thanks for any help.

Hello

From the logs and the symptoms it seems that there is a problem with the “/usr/NX/var/log/nxerror.log” file access as every nxnode process reports:

2019-03-21 16:56:30 288.624 1376 NXSERVER Parse local node message ‘NX> 596 Error: Cannot open /usr/NX/var/log/nxerror.log – ‘Permission denied’.\n’ on FD#14.

and then closes.

This matches with file access rights from the log directory you provided. It seems that two of our log files nxerror.log and nxd.log have wrong access rights 600. Please ascertain if it is the same on your machine.

Proper access rights to those files should be:

stat /usr/NX/var/log/nxd.log
Access: (0644/-rw-r–r–) Uid: ( 123/ nx) Gid: ( 0/ root)

stat /usr/NX/var/log/nxerror.log
Access: (0662/-rw-rw–w-) Uid: ( 123/ nx) Gid: ( 0/ root)

So here in this case running

# chmod 644 /usr/NX/var/log/nxd.log
# chmod 662 /usr/NX/var/log/nxerror.log

And then restarting the nxserver:

# /etc/NX/nxserver –restart

Should fix the issue.
