rpcinfo makes an RPC call to an RPC server and reports
  what it finds.
In the first synopsis, rpcinfo lists all
    the registered RPC services with rpcbind on
    host. If host is not specified,
    the local host is the default. If -s is used, the
    information is displayed in a concise format.
In the second synopsis, rpcinfo lists all
    the RPC services registered with rpcbind, version 2.
    Also note that the format of the information is different in the first and
    the second synopsis. This is because the second synopsis is an older
    protocol used to collect the information displayed (version 2 of the
    rpcbind protocol).
The third synopsis makes an RPC call to procedure 0 of
    prognum and versnum on the
    specified host and reports whether a response was
    received. transport is the transport which has to be
    used for contacting the given service. The remote address of the service is
    obtained by making a call to the remote rpcbind.
The prognum argument is a number that
    represents an RPC program number. If a versnum is
    specified, rpcinfo attempts to call that version of
    the specified prognum. Otherwise,
    rpcinfo attempts to find all the registered version
    numbers for the specified prognum by calling version
    0, which is presumed not to exist; if it does exist,
    rpcinfo attempts to obtain this information by
    calling an extremely high version number instead, and attempts to call each
    registered version. Note: the version number is required for the
    -b and -d options.
  - -Ttransport
- Specify the transport on which the service is required. If this option is
      not specified, rpcinfouses the transport
      specified in theNETPATHenvironment variable, or
      if that is unset or null, the transport in the
      netconfig(5) database is
      used. This is a generic option, and can be used in conjunction with other
      options as shown in the SYNOPSIS.
- -aserv_address
- Use serv_address as the (universal) address for the
      service on transport to ping procedure 0 of the
      specified prognum and report whether a response was
      received. The -Toption is required with the-aoption.If versnum is not specified,
        rpcinfotries to ping all available version
        numbers for that program number. This option avoids calls to remoterpcbindto find the address of the service. The
        serv_address is specified in universal address
        format of the given transport.
 
- -b
- Make an RPC broadcast to procedure 0 of the specified
      prognum and versnum and report
      all hosts that respond. If 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 effect
      on other systems.
- -d
- Delete registration for the RPC service of the specified
      prognum and versnum. If
      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 super-user who can delete any
    service.
- -l
- Display 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.
- -m
- Display a table of statistics of rpcbindoperations on the given host. The table shows
      statistics for each version ofrpcbind(versions
      2, 3, and 4), giving the number of times each procedure was requested and
      successfully serviced, the number and type of remote call requests that
      were made, and information about RPC address lookups that were handled.
      This is useful for monitoring RPC activities on
      host.
- -nportnum
- Use portnum as the port number for the
      -tand-uoptions instead
      of the port number given byrpcbind. Use of this
      option avoids a call to the remoterpcbindto find
      out the address of the service. This option is made obsolete by the-aoption.
- -p
- Probe rpcbindon host using
      version 2 of therpcbindprotocol, and display a
      list of all registered RPC programs. If host is not
      specified, it defaults to the local host. Note: version 2 of therpcbindprotocol was previously known as the
      portmapper protocol.
- -s
- Display a concise list of all registered RPC programs on
      host. If host is not
      specified, it defaults to the local host.
- -t
- Make an RPC call to procedure 0 of prognum on the
      specified host using TCP, and report whether a
      response was received. This option is made obsolete by the
      -Toption as shown in the third synopsis.
- -u
- Make an RPC call to procedure 0 of prognum on the
      specified host using UDP, and report whether a
      response was received. This option is made obsolete by the
      -Toption as shown in the third synopsis.
To show all of the RPC services registered on the local machine use:To show all of the RPC services registered with
    rpcbind on the machine named
    klaxon use:
The information displayed by the above commands can be quite
    lengthy. Use the -s option to display a more concise
    list:
	example% rpcinfo -s klaxon
 
  
    | program | version(s) | netid(s) | service | owner | 
  
    | 100000 | 2,3,4 | local,tcp,udp,tcp6,udp6 | rpcbind | super-user | 
  
    | 100008 | 1 | udp,tcp,udp6,tcp6 | walld | super-user | 
  
    | 100002 | 2,1 | udp,udp6 | rusersd | super-user | 
  
    | 100001 | 2,3,4 | udp,udp6 | rstatd | super-user | 
  
    | 100012 | 1 | udp,tcp | sprayd | super-user | 
  
    | 100007 | 3 | udp,tcp | ypbind | super-user | 
To show whether the RPC service with program number
    prognum and version versnum is
    registered on the machine named klaxon for the
    transport TCP use:
	example% rpcinfo -T tcp klaxon prognum versnum
 
To show all RPC services registered with version 2 of the
    rpcbind protocol on the local machine use:
To delete the registration for version 1 of the
    walld (program number 100008) service for all
    transports use:
	example# rpcinfo -d 100008 1
 
or
	example# rpcinfo -d walld 1
