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
This program is available with the Networking software installation
option. Refer to for information on how to install optional software.
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 regis-
tered 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 ver-
sion 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 Network
Information Service (NIS) use:
example% rpcinfo -b ypserv 'version' | uniq
where 'version' is the current NIS 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
RPC Programming Guide in
In releases prior to the SunOS 3.0 release, 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
The Network Information Service (NIS) was formerly known as Sun Yellow
Pages (YP). The functionality of the two remains the same; only the
name has changed.
