Local configuration

To use the secure rcmds, two local principals must exist for every network interface to which they can be connected.

The two local principals are:
              host/FullInterfaceName@Realmname
              ftp/FullInterfaceName@Realmname
where FullInterfaceName is the interface name and domain name and RealmName is he name of the local Kerberos Version 5 realm.
