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. 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.
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.
EXAMPLES¶
To show all of the RPC services registered on the local machine use:
To show all of the RPC services registered with
rpcbind
on the machine named
klaxon
use:
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

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:
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
