NAME

rpcinfo − report RPC information

SYNOPSIS

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

AVAILABILITY

This program is available with the Networking Tools and Programs software installation option.  Refer to Installing the SunOS for information on how to install optional software. 

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. 

−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-user.

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:

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. 

To delete the registration for version 1 of the walld service use:

example% 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.
