Changing server setting when not allowed to do sudo su

[gcollins]

Hi,

When I try to change Server Settings on the UI (Ubuntu 20.04), I get the error “Authentication failed, please try again”.

When I look in /var/log/auth.log it appears that NoMachine is trying to do a “sudo su” which I am not allowed to do on this machine:

I see the command NoMachine is trying to run from sudo is:

/usr/bin/su -l root -c pwd

Anyway around this? I know I can run these commands from the command line to stop/start the server:

sudo /etc/NX/nxserver --shutdown/--startup

But I was hoping to use the UI

Thanks!

Hello gcollins,

Can you try to use root’s credentials in prompt asking for user with administrative rights?

[gcollins]

I don’t have root credentials, only sudo with restrictions (i.e. no sudo su and restrictions on stopping specific services)

NoMachine allows administrative operations to be performed on Linux only by root account or by demonstrating administrative privileges by being able to ‘sudo su’.
