MUNGE

The munge package.

MUNGE (MUNGE Uid 'N' Gid Emporium) is an authentication service for creating and validating credentials.

A secret key must be created before starting the service for the first time. This can be done with the following command:

sudo -u munge /usr/sbin/mungekey -v

Please read man 8 mungekey for more information. In the second step you can start and enable the munge service.

systemctl start munge
systemctl enable munge
