     rpcinfo — report RPC information

SYNOPSIS         top

     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         top

     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         top

     -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         top

     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(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:

             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
