NAME [Toc] [Back]
rpcinfo - report RPC information
SYNOPSIS [Toc] [Back]
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 [Toc] [Back]
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
(see rpc(4)).
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 that the version number is required for -b and -d options.
The other ways of using rpcinfo are described in the EXAMPLES section.
Options [Toc] [Back]
-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(4) 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 that 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 [Toc] [Back]
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
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:
Hewlett-Packard Company - 3 - HP-UX 11i Version 2: August 2003
rpcinfo(1M) rpcinfo(1M)
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
