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.
