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 theNETPATH
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 remoterpcbind
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 ofrpcbind
(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 byrpcbind
. Use of this option avoids a call to the remoterpcbind
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 therpcbind
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 therpcbind
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 | version | netid | 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
