## NAME
     **rpcinfo** — report RPC information

## SYNOPSIS
     **rpcinfo** [**-m** | **-s**] [_host_]
     **rpcinfo** **-p** [_host_]
     **rpcinfo** **-T** _transport_ _host_ _prognum_ [_versnum_]
     **rpcinfo** **-l** [**-T** _transport_] _host_ _prognum_ _versnum_
     **rpcinfo** [**-n** _portnum_] **-u** _host_ _prognum_ [_versnum_]
     **rpcinfo** [**-n** _portnum_] [**-t**] _host_ _prognum_ [_versnum_]
     **rpcinfo** **-a** _serv_address_ **-T** _transport_ _prognum_ [_versnum_]
     **rpcinfo** **-b** [**-T** _transport_] _prognum_ _versnum_
     **rpcinfo** **-d** [**-T** _transport_] _prognum_ _versnum_

## DESCRIPTION
     **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 dis‐
     played 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 dis‐
     played (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 speci‐
     fied, **rpcinfo** attempts to call that version of the specified _prognum_.  Otherwise, **rpcinfo** at‐
     tempts 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 informa‐
     tion by calling an extremely high version number instead, and attempts to call each registered
     version.  Note: the version number is required for **-b** and **-d** options.

## OPTIONS
### -T
             Specify the transport on which the service is required.  If this option is not speci‐
             fied, **rpcinfo** uses the transport specified in the NETPATH environment variable, or if
             that is unset or null, the transport in the [netconfig(5)](https://www.chedong.com/phpMan.php/man/netconfig/5/markdown) database is used.  This is a
             generic option, and can be used in conjunction with other options as shown in the SYN‐
             OPSIS.

### -a
             Use _serv_address_ as the (universal) address for the service on _transport_ to ping proce‐
             dure 0 of the specified _prognum_ and report whether a response was received.  The **-T** op‐
             tion is required with the **-a** option.

             If _versnum_ is not specified, **rpcinfo** tries to ping all available version numbers for
             that program number.  This option avoids calls to remote **rpcbind** to find the address of
             the service.  The _serv_address_ is specified in universal address format of the given
             transport.

### -b
             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
             _transport_ is specified, unregister the service on only that transport, otherwise unreg‐
             ister 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
             tries are returned for all transports in the same protocol family as that used to con‐
             tact the remote **rpcbind**.

### -m
             statistics for each version of **rpcbind** (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_.

### -n
             Use _portnum_ as the port number for the **-t** and **-u** options instead of the port number
             given by **rpcbind**.  Use of this option avoids a call to the remote **rpcbind** to find out
             the address of the service. This option is made obsolete by the **-a** option.

### -p
             all registered RPC programs.  If _host_ is not specified, it defaults to the local host.
             Note: Version 2 of the **rpcbind** protocol was previously known as the portmapper proto‐
             col.

### -s
             fied, it defaults to the local host.

### -t
             whether a response was received. This option is made obsolete by the **-T** option as shown
             in the third synopsis.

### -u
             whether a response was received. This option is made obsolete by the **-T** option as shown
             in the third synopsis.

## EXAMPLES
     To show all of the RPC services registered on the local machine use:

             example% rpcinfo

     To show all of the RPC services registered with **rpcbind** on the machine named **klaxon** use:

             example% rpcinfo klaxon

     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   netid                     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:

             example% rpcinfo -p

     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
