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

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 Network Information service use:

example% rpcinfo -b ypserv ’version’ | uniq

where ’version’ is the current Network Information Service 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 NFSSRC 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.
