RPCINFO(8) BSD System Manager's Manual RPCINFO(8)
rpcinfo — report RPC information
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
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. 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.
-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 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: 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.
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
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
