RPCINFO(8) BSD System Manager's Manual RPCINFO(8)
NAME
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 for-
mat.
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 sec-
ond synopsis is an older protocol used to collect the information dis-
played (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 mak-
ing 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 regis-
tered 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 spec-
ified, it broadcasts its request only on the specified transport.
If broadcasting is not supported by any transport, an error mes-
sage 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 ser-
vice. 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 pro-
tocol.
-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(s) netid(s) 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 proto-
col 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
