Resolution

Migrate Robot from Non-Root user to Root User on Linux follow the steps below:

On your Linux server, perform the following steps to migrate the robot running with non-root permission to run as a root user.

Follow these steps:

1. Stop the nimsoft service.
   
   
2. Change the permission and ownership of the Nimsoft folder to the root user using the following commands
   
   chown -R root: nimsoft OR chown -R root:root nimsoft
chmod -R 755 nimsoft
   
   
3. Remove the non-root user details from the /etc/nimbus.conf file
   
   Eg: Remove any value specified in the key NIMBUS_USR=
   
   The file can be left as below: 
   
   
   
   
   
4. Change the following settings:
   
   
   1. a. Linux: Execute the systemctl status nimbus.service command to see where the service is getting stored and edit the nimbus service file.
      
      
          NOTE: Edit the file only if the loaded unit is nimbus.service
      
      b. Ubuntu/RHEL: Remove the non-root User and group from the nimbus.service file.

   Example: 
   If User and group are populate as below: 
   
    [Service]
  Type=forking
  Restart=always
  User=Example_user
  Group=Example_group


Remove only the user and group values. Leave it as: 
   
   
    [Service]
  Type=forking
  Restart=always
  User=
  Group=
   
   
   
   

   c. Debian/SUSE: The service file already contains a script to read the user from /etc/nimbus.conf and run the probes as a specific user.

   
   
   
5. Reload the Nimbus service using the systemctl daemon-reload command
