rpcinfo - report RPC information
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
rpcinfo makes an RPC call to an RPC server and reports what it finds.
-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.
-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 super-
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:
example% rpcinfo -p
To show all of the RPC services registered on the machine named klaxon
example% rpcinfo -p klaxon
To show all machines on the local net that are running the Yellow Pages
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

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.
