Hi all. I am installing the free version of NoMachine on a RHEL 6 machine. I installed the NoMachine 6.9.2 RPM without a problem, but I can’t figure out what I am configuring incorrectly. The system already has the “nx” UID and GID defined. I copied /usr/NX/scripts/init/nxserver to /etc/init.d, but starting the service fails:
service nxserver restart
[root@dlasist2 NX]# service nxserver restart
[root@dlasist2 NX]# 31753 31753 18:47:35 601 nxexecExecute: ERROR! Can’t retrieve user info.
31753 31753 18:47:35 601 nxexecExecute: ERROR! Error is Success
NX> 900 NXSERVER – Version 6.9.2 – LS
followed by all the help text for nxserver. We have another RHEL 6 system that is running an older version of NoMachine without a problem, and I’ve tried to make sure the /etc/init.d/nxserver script and the /usr/NX/etc/server.cfg files are analogous.
Looking at the error logs, I see things like:
13674 13674 18:36:03 670.532 Process: ERROR! Cannot get information for user id ‘20000’.
13674 13674 18:36:03 670.602 Process: ERROR! Error is 2, No such file or directory.
13674 13674 18:36:03 670.612 HostGetUserInfoByUid: WARNING! Failed to get process user information.
Unknown option: daemon
In nxserver.log I see:
2020-01-27 18:36:03 670.779 13674 NXSERVER WARNING! Cannot get user info for 20000.
2020-01-27 18:36:03 670.901 13674 NXSERVER WARNING! Error is: 2, ‘No such file or directory’.
The UID/GID for nx is 225 on the working and non-working machines. But it looks like the error messages indicate the nxserver is trying to launch under UID 20000 – which is the port range base, right?
Is there some other configuration change I need to make? The web page for installing and configuring the free version does not discuss any of this.
Thanks in advance,
