NAME
rpcinfo - report RPC information
SYNOPSIS
rpcinfo [host]
rpcinfo -p [host]
rpcinfo -T transport host program version
rpcinfo [-n portnum] -u host program version
rpcinfo [-n portnum] -t host program version
rpcinfo -a serv_address -T transport program [version]
rpcinfo -b [-T transport] program version
rpcinfo -d [-T transport] program version
DESCRIPTION
rpcinfo makes an RPC call to an RPC server and reports what it finds.
In the first synopsis, it lists all the registered RPC services with
rpcbind on host. If host is not specified, it defaults to the local
host.
In the second synopsis, it lists all the RPC services registered with
portmapper. Also note that the format of the information is different in
the first and the second synopsis; this is because in the first case,
rpcbind (version 3) is contacted, while in the second case portmap
(version 2) is contacted for information.
The third synopsis makes an RPC call to procedure 0 of program and
version 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 remote rpcbind.
The other ways of using rpcinfo are described below. See EXAMPLES.
The following options are available:
-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, in the netconfig database.
This is a generic option, and can be used in conjunction
with any other option, except the -b option.
-a serv_address
Use serv_address as the (universal) address for the
service on transport, to ping procedure 0 of the specified
program and report whether a response was received. The
use of -T option is required with -a option.
If version number is not specified, rpcinfo tries to ping
all the 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
program and version and report all hosts that respond. If
transport is specified, it broadcasts its request only on
the transport specified through transport. If
broadcasting is not supported by any transport, an error
message is printed. Only UDP transports support
broadcasting.
-d Delete registration for the RPC service of the specified
program and version. If transport is specified,
unregister the service on only that transport, otherwise
unregister the services on all the transports on which it
was registered. This option can be exercised only by the
privileged user.
-n Use portnum as the port number for the -t and -u options
instead of the port number given by the portmapper. Use
of this option avoids a call to the remote portmapper to
find out the address of the service.
-p Probe the portmapper on host, and print a list of all
registered RPC programs. If host is not specified, it
defaults to the local host.
-t Make an RPC call to procedure 0 of program on the
specified host using TCP, and report whether a response
was received.
-u Make an RPC call to procedure 0 of program on the
specified host using UDP, and report whether a response
was received.
The program argument is a number.
If a version is specified, rpcinfo attempts to call that version of the
specified program. Otherwise, rpcinfo attempts to find all the
registered version numbers for the specified program 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.
EXAMPLES
To show all of the RPC services registered on the local machine use:
$ rpcinfo

rpcinfo(1M) UNIX System V rpcinfo(1M)
To show all of the RPC services registered with rpcbind on the machine
named klaxon use:
$ rpcinfo klaxon
To show if the RPC service with program number prog_no and version vers
is registered on the machine named klaxon for the transport tcp use:
$ rpcinfo -T tcp klaxon prog_no vers
To show all of the RPC services registered with the portmapper on the
local machine use:
$ rpcinfo -p
To ping version 2 of rpcbind (program number 100000) on host sparky:
$ rpcinfo -t sparky 100000 2
To delete the registration for version 1 of the walld (program number
100008) service for all transports use:
# rpcinfo -d 100008 1
