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 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 -b and -d options.

OPTIONS

     -T transport
             Specify the transport on which the service is required.  If this
             option is not specified, rpcinfo uses the transport specified in
             the NETPATH environment 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.

     -a serv_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 -T option 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      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 rpcbind operations on the given
             host.  The table shows 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 portnum
             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      Probe rpcbind on host using version 2 of the rpcbind protocol,
             and display a list of 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
             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 -T option 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 -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
