- NAME
- rpcinfo - report RPC information
-
- SYNOPSIS
- `rpcinfo -p [ host ]'
-
- `rpcinfo [ -n portnum ] -u host program [ version ]'
-
- `rpcinfo [ -n portnum ] -t host program [ version ]'
-
- `rpcinfo -b program version'
-
- `rpcinfo -d program version'
-
- DESCRIPTION
- `rpcinfo' makes an RPC call to an RPC server and reports what it
- finds.
-
- OPTIONS
- `-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 `gethostname()'.
-
- `-u' Make an RPC call to procedure 0 of program on the specified
- host using UDP, and report whether a response was received.
-
- `-t' Make an RPC call to procedure 0 of program on the specified
- host using TCP, and report whether a response was received.
-
- `-n' Use `portnum' as the port number for the `-t' and `-u'
- options instead of the port number given by the portmapper.
-
- `-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. This option can be exercised only by
- the superuser. 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.
-
- EXAMPLES
- To show all of the RPC services registered on the local machine
- use:
-
- example% rpcinfo -p
-
- To show all of the RPC services registered on the machine named
- klaxon use:
-
- example% rpcinfo -p klaxon
-
- To show all machines on the local net that are running the Yellow
- Pages service use:
-
- example% 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:
-
- example% rpcinfo -d walld 1
