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:
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 Ta version Ta netid Ta service Ta owner
- 100000 Ta 2,3,4 Ta local,tcp,udp,tcp6,udp6 Ta rpcbind Ta super-user
- 100008 Ta 1 Ta udp,tcp,udp6,tcp6 Ta walld Ta super-user
- 100002 Ta 2,1 Ta udp,udp6 Ta rusersd Ta super-user
- 100001 Ta 2,3,4 Ta udp,udp6 Ta rstatd Ta super-user
- 100012 Ta 1 Ta udp,tcp Ta sprayd Ta super-user
- 100007 Ta 3 Ta udp,tcp Ta ypbind Ta 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
