RPCINFO(8) Maintenance Commands and Procedures RPCINFO(8)

NAME

rpcinfo - report RPC information

SYNOPSIS

rpcinfo [-T transport] [-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 format.


In the second synopsis, rpcinfo lists all the RPC services registered
with rpcbind, version 2. 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(5)).


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 EXAMPLES section describe other ways of using rpcinfo.

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 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
superuser, 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. This option is not useful for IPv6; use -s
(see below) instead. 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

Example 1 RPC services.


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 tcp,udp,ticlts,ticots,ticotsord rpcbind superuser
100008 1 ticotsord,ticots,ticlts,udp,tcp walld superuser
100002 2,1 ticotsord,ticots,ticlts,udp,tcp rusersd superuser
100001 2,3,4 ticotsord,ticots,tcp,ticlts,udp rstatd superuser
100012 1 ticotsord,ticots,ticlts,udp,tcp sprayd superuser
100007 3 ticotsord,ticots,ticlts,udp,tcp ypbind superuser
100029 1 ticotsord,ticots,ticlts keyserv superuser
100078 4 ticotsord,ticots,ticlts - superuser
100024 1 ticotsord,ticots,ticlts,udp,tcp status superuser
100021 2,1 ticotsord,ticots,ticlts,udp,tcp nlockmgr superuser
100020 1 ticotsord,ticots,ticlts,udp,tcp llockmgr superuser


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
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
