rpcinfo makes an RPC call to an RPC server and reports what it finds.
In the first synopsis,
rpcinfo lists all the registered RPC services with
rpcbind on
host. If
host is not specified, the local host is the default. If
-s is used, the information is displayed in a concise format.
In the second synopsis,
rpcinfo lists all the RPC services registered with
rpcbind, version 2. Also note that the format of the information is different in the first and the second synopsis. This is because the second synopsis is an older protocol used to collect the information displayed (version 2 of the
rpcbind protocol).
The third synopsis makes an RPC call to procedure 0 of
prognum and
versnum on the specified
host and reports whether a response was received.
transport is the transport which has to be used for contacting the given service. The remote address of the service is obtained by making a call to the remote
rpcbind.
The
prognum argument is a number that represents an RPC program number. If a
versnum is specified,
rpcinfo attempts to call that version of the specified
prognum. Otherwise,
rpcinfo attempts to find all the registered version numbers for the specified
prognum 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.
