Linux Dropped Privileges

Since the version v0.43 the default Linux installation will run the snclient as user snclient with dropped privileges.

However, in order to perform certain checks, the snclient binary will make use of capabilities to start some sub processes as root user. For example the omd check requires root permissions.

Run as root again

In case you need to run snclient as root user again, you can change the user name in an systemd override setting:

Edit the snclient service by running this command:

sudo systemctl edit snclient.service

and add the override:

[Service]
User=root
