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 empty, the transport in the netconfig(5) database is used. This is a generic option, and can be used in conjunction with other options as shown in the SYNOPSIS.
-a serv_address
Use serv_address as the (universal) address for the service on transport to ping procedure 0 of the specified prognum and report whether a response was received. The -T option is required with the -a option.
If versnum is not specified, rpcinfo tries to ping all 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 prognum and versnum and report all hosts that respond. If transport is specified, it broadcasts its request only on the specified transport. If broadcasting is not supported by any transport, an error message is printed. Use of broadcasting should be limited because of the potential for adverse effect on other systems.
-d
Delete registration for the RPC service of the specified prognum and versnum. If transport is specified, unregister the service on only that transport, otherwise unregister the service on all the transports on which it was registered. Only the owner of a service can delete a registration, except the super-user who can delete any service.
-l
Display a list of entries with a given prognum and versnum on the specified host. Entries are returned for all transports in the same protocol family as that used to contact the remote rpcbind.
-m
Display a table of statistics of rpcbind operations on the given host. The table shows statistics for each version of rpcbind (versions 2, 3 and 4), giving the number of times each procedure was requested and successfully serviced, the number and type of remote call requests that were made, and information about RPC address lookups that were handled. This is useful for monitoring RPC activities on host.
-n portnum
Use portnum as the port number for the -t and -u options instead of the port number given by rpcbind. Use of this option avoids a call to the remote rpcbind to find out the address of the service. This option is made obsolete by the -a option.
-p
Probe rpcbind on host using version 2 of the rpcbind protocol, and display a list of all registered RPC programs. If host is not specified, it defaults to the local host. Note: Version 2 of the rpcbind protocol was previously known as the portmapper protocol.
-s
Display a concise list of all registered RPC programs on host. If host is not specified, it defaults to the local host.
-t
Make an RPC call to procedure 0 of prognum on the specified host using TCP, and report whether a response was received. This option is made obsolete by the -T option as shown in the third synopsis.
-u
Make an RPC call to procedure 0 of prognum on the specified host using UDP, and report whether a response was received. This option is made obsolete by the -T option as shown in the third synopsis.
