The
utility makes an RPC call to an RPC
server and reports what it finds.
In the first synopsis,
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,
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,
attempts to call that version of the specified
prognum
Otherwise,
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,
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,
uses the transport specified in the
NETPATH
environment variable, or if that is unset or empty, 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
Sx 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,
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:
"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:
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:
