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
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
