Note that version 2 of the rpcbind
protocol was previously known as the portmapper
protocol.
-t Makes an RPC call to procedure 0 of prognum on the
specified host using TCP, and reports whether a
response was received. This option is made obsolete
by the -T option as shown in the third synopsis.
-l Displays a list of entries with a given prognum and
versnum on the specified host. Entries are returned for
all transports in the same protocol family as that used
to contact the remote rpcbind.
-b Makes an RPC broadcast to procedure 0 of the
specified prognum and versnum and reports all hosts
that respond. If the transport is specified, it broadcasts
its request only on the specified transport. If
broadcasting is not supported by any transport, an
error message is printed. Use of broadcasting should
be limited because of the potential for adverse effects
on other systems.

Nmblookup -d Deletes registration for the RPC service of the
specified prognum and versnum. If the transport is
specified, unregister the service on only that transport;
otherwise unregister the service on all the transports
on which it was registered. Only the owner of a service
can delete a registration, except the superuser, who can
delete any service.
-u Makes an RPC call to procedure 0 of prognum on the
specified host using UDP, and report whether a
response was received.
