rpcinfo(NADM)

rpcinfo -- report RPC information

Syntax

rpcinfo -p [ host ]

rpcinfo [ -n portnum ] -u host program [ version ]

rpcinfo [ -n portnum ] -t host program [ version ]

rpcinfo -b 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 hostname(TC).
-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

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 the -b option.

Examples

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 which are running the Network Information Service, use:

rpcinfo -b ypserv version | uniq

where version is the current Network Information Service version obtained from the results of the -p switch above.
