Check or Attack Name: Ugidd Check

The rpc.ugidd daemon is used on older Linux installations to translate between user names and user IDs. This daemon allows a remote attacker to enumerate all the users on a given machine.

Remove or disable the rpc.ugidd daemon, if it is not necessary in your configuration.
