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 informa-
tion 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 for-
mat 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 prog-
num 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 pro-
gram 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: the version number is required for -b and -d options.

The other ways of using rpcinfo are described in the EXAM-
PLES section.

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 netcon-
fig(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 pro-
cedure 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 tran-
sport.

-b Make an RPC broadcast to procedure 0 of the
specified prognum and versnum and report all
hosts that respond. If transport is speci-
fied, 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 tran-
sport 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 prog-
num and versnum on the specified host.
Entries are returned for all transports in
the same protocol family as that used to con-
tact 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 suc-
cessfully 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: 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
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 super-
user
100008 1 ticotsord,ticots,ticlts,udp,tcp walld super-
user
100002 2,1 ticotsord,ticots,ticlts,udp,tcp rusersd super-
user
100001 2,3,4 ticotsord,ticots,tcp,ticlts,udp rstatd super-
user
100012 1 ticotsord,ticots,ticlts,udp,tcp sprayd super-
user
100007 3 ticotsord,ticots,ticlts,udp,tcp ypbind super-
user
100029 1 ticotsord,ticots,ticlts keyserv super-
user
100078 4 ticotsord,ticots,ticlts kerbd super-
user
100024 1 ticotsord,ticots,ticlts,udp,tcp status super-
user
100021 2,1 ticotsord,ticots,ticlts,udp,tcp nlockmgrsuper-
user
100020 1 ticotsord,ticots,ticlts,udp,tcp llockmgrsuper-
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 protocol on the local machine use:

example% rpcinfo -p

To delete the registration for version 1 of the walld (pro-
gram number 100008) service for all transports use:

example# rpcinfo -d 100008 1

or

example# rpcinfo -d walld 1
