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 servaddress -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 port-
map (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 contact-
ing 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.

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, in
the netconfig database. This is a generic option, and can be used
in conjunction with any other option, except the -b option.
-a servaddress
Use servaddress 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 ser-
vice. The servaddress 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 speci-
fied, it broadcasts its request only on the transport specified
through transport. If broadcasting is not supported by any trans-
port, 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 exer-
cised 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 ver-
sion 0, which is presumed not to exist; if it does exist, rpcinfo
attempts to obtain this information by calling an extremely high ver-
sion 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 progno and version
vers is registered on the machine named klaxon for the transport tcp
use:
$ rpcinfo -T tcp klaxon progno 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
