rpcinfo(1M) — ADMINISTRATOR COMMANDS
NAME
rpcinfo − report RPC information
SYNOPSIS
rpcinfo [host]
rpcinfo -p [host]
rpcinfo -T transport host program version
rpcinfo [-n portnum] -u host program version
rpcinfo [-n portnum] -t host program version
rpcinfo -a serv_address -T transport program [version]
rpcinfo -b [-T transport] program version
rpcinfo -d [-T transport] program version
DESCRIPTION
rpcinfo makes an RPC call to an RPC server and reports what it finds.
In the first synopsis, it lists all the registered RPC services with rpcbind on host. If host is not specified, it defaults to the local host.
In the second synopsis, it lists all the RPC services registered with portmapper. Also note that the format of the information is different in the first and the second synopsis; this is because in the first case, rpcbind (version 3) is contacted, while in the second case portmap (version 2) is contacted for information.
The third synopsis makes an RPC call to procedure 0 of program and version 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 remote rpcbind.
The other ways of using rpcinfo are described below. See EXAMPLES.
The following options are available:
−T transport Specify the transport on which the service is required. If this option is not specified, rpcinfo uses the transport specified in the NETPATH environment variable, or if that is unset or null, in the netconfig database. This is a generic option, and can be used in conjunction with any other option, except the −b option.
−a serv_address Use serv_address as the (universal) address for the service on transport, to ping procedure 0 of the specified program and report whether a response was received. The use of −T option is required with −a option.
If version number is not specified, rpcinfo tries to ping all the available version numbers for that program number. This option avoids calls to remote rpcbind to find the address of the service. The serv_address is specified in universal address format of the given transport.
−b Make an RPC broadcast to procedure 0 of the specified program and version and report all hosts that respond. If transport is specified, it broadcasts its request only on the transport specified through transport. If broadcasting is not supported by any transport, an error message is printed. Only UDP transports support broadcasting.
−d Delete registration for the RPC service of the specified program and version. If transport is specified, unregister the service on only that transport, otherwise unregister the services on all the transports on which it was registered. This option can be exercised only by the privileged user.
−n Use portnum as the port number for the −t and −u options instead of the port number given by the portmapper. Use of this option avoids a call to the remote portmapper to find out the address of the service.
−p Probe the portmapper on host, and print a list of all registered RPC programs. If host is not specified, it defaults to the local host.
−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 is 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
To show all of the RPC services registered with rpcbind on the machine named klaxon use:
$ rpcinfo klaxon
To show if the RPC service with program number prog_no and version vers is registered on the machine named klaxon for the transport tcp use:
$ rpcinfo −T tcp klaxon prog_no vers
To show all of the RPC services registered with the portmapper on the local machine use:
$ rpcinfo −p
To ping version 2 of rpcbind (program number 100000) on host sparky:
$ rpcinfo -t sparky 100000 2
To delete the registration for version 1 of the walld (program number 100008) service for all transports use:
# rpcinfo −d 100008 1
