RPCINFO(8) OpenBSD System Manager's Manual RPCINFO(8)NAMErpcinfo - report RPC information
SYNOPSISrpcinfo-b program version
rpcinfo-d program version
rpcinfo-p [host]
rpcinfo-s program version port
rpcinfo [-n portnum] -t host program [version]
rpcinfo [-n portnum] -u host program [version]
DESCRIPTIONrpcinfo makes an RPC call to an RPC server and reports what it finds.
The options are as follows:
-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. Registrations which point at ports numbered below
1024 can only be deleted by the superuser.
-n portnum
Use portnum as the port number for the -t and -u options instead
of the port number given by the portmapper.
-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).
-s Create a registration for the RPC service of the specified
program and version, located at port port. Registrations which
point at ports numbered below 1024 can only be created (or
changed) by the superuser.
-t Make an RPC call to procedure 0 of program on the specified host
using TCP, and report whether a response was received.
-u Make an RPC call to procedure 0 of program on the specified host
using UDP, and report whether a response was received.
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.
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 that are running the Yellow Pages
service use:
$ 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:
$ rpcinfo-d walld 1

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.
