RPCINFO(8)              OpenBSD System Manager's Manual             RPCINFO(8)

NAME
     rpcinfo - report RPC information

SYNOPSIS
     rpcinfo -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]

DESCRIPTION
     rpcinfo 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 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 in-
     stead) 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 re-
     sults 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.
