rpcinfo makes an RPC call to an RPC server
and reports what it finds.
The options are as follows:
-
-
-b- Make an RPC broadcast to procedure 0 of the specified
program and
version using UDP and report all hosts
that respond.
-
-
-d- Delete registration for the RPC service of the specified
program and
version. Registrations which point at
ports numbered below 1024 can only be deleted by the superuser.
-
-
-n
portnum- Use portnum as the port number for the
-t and
-u options instead of the port number
given by the portmapper.
-
-
-p- Probe the portmapper on host, and print a
list of all registered RPC programs. If
host is not specified, it defaults to the
value returned by
hostname(1).
-
-
-s- Create a registration for the RPC service of the specified
program and
version, located at port
port. Registrations which point at ports
numbered below 1024 can only be created (or changed) by the
superuser.
-
-
-t- Make an RPC call to procedure 0 of
program on the specified
host using TCP, and report whether a
response was received.
-
-
-u- Make an RPC call to procedure 0 of
program on the specified
host using UDP, and report whether a
response was received.
The
program argument can be either a name or a
number.
If a
version is specified,
rpcinfo attempts to call that version of
the specified
program. Otherwise,
rpcinfo attempts to find all the registered
version numbers for the specified
program 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.
To show all of the RPC services registered on the local machine use:
$ rpcinfo -p
To show all of the RPC services registered on the machine named
klaxon use:
$ rpcinfo -p klaxon
To show all machines on the local net that are running the Yellow Pages service
use:
$ rpcinfo -b ypserv 'version' |
uniq
where 'version' is the current Yellow Pages version obtained from the results of
the
-p switch above.
To delete the registration for version 1 of the
walld service use:
$ rpcinfo -d walld 1
rpc(5),
portmap(8)
