     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
