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.
