RPCINFO(8) BSD System Manager's Manual RPCINFO(8)
NAME
rpcinfo -- report RPC information
SYNOPSIS
rpcinfo [-m | -s] [host]
rpcinfo -p [host]
rpcinfo -T transport host prognum [versnum]
rpcinfo -l [-T transport] host prognum versnum
rpcinfo [-n portnum] -u host prognum [versnum]
rpcinfo [-n portnum] [-t] host prognum [versnum]
rpcinfo -a serv_address -T transport prognum [versnum]
rpcinfo -b [-T transport] prognum versnum
rpcinfo -d [-T transport] prognum versnum
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 in-
formation 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 ob-
tain 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 spec-
ified, 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 po-
tential 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 un-
register 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 num-
ber 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 portmap-
per protocol.
-s Display a concise list of all registered RPC programs on host. If host is not spec-
ified, it defaults to the local host.
-t Make an RPC call to procedure 0 of prognum on the specified host using TCP, and re-
port 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 re-
port 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 regis-
tered 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 ma-
chine 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
