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
