rpcinfo -d program version
Neutrino
- -b program version
 
- Using UDP, make an RPC broadcast to procedure 0 of the
      specified program and version, and
      report all hosts that respond.
  
 
- -d program version
 
- Delete the registration for the RPC service of the 
      specified program and version. Only
      the superuser can use this option.
  
 
- -n portnum
 
- Use portnum as the port number for the
      -t and -u options instead of the port
      number given by the portmapper.
 
- -p [host]
 
- Probe the portmapper on host and print a list
      of all registered RPC programs. If a host isn't specified,
      use the standard hostname for the current processor.
 
- -t host program
 
- Using TCP, make an RPC call to procedure 0 of
      program on the specified host and
      report whether a response was received.
 
- -u host program
 
- Using UDP, make an RPC call to procedure 0 of
      program on the specified host and
      report whether a response was received.
 
- program
 
- A name or a number of a program, as listed by the
      -p option.
 
- version
 
- A version of the specified program. If you don't specify
      a version, rpcinfo looks for all the registered
      version numbers for the specified program and then tries to
      call each registered version. To find all of a program's
      version numbers, rpcinfo calls version 0, which
      is presumed not to exist. If it does exist,
      rpcinfo tries to obtain this information by
      calling an extremely high version number instead.
 
The rpcinfo utility makes an RPC call to an RPC 
server and reports what it finds.
