RPCINFO(8C) — UNIX Programmer’s Manual
NAME
rpcinfo − report RPC information
SYNOPSIS
rpcinfo −p [ host ]
rpcinfo −u host program [ version ]
rpcinfo −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(1).
−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.
−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:
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.

BUGS
In releases prior to SunOS 3.0, the Network File System (NFS) did not register itself with the portmapper; rpcinfo cannot be used to make RPC calls to the NFS server on hosts running such releases.
