On Unix-like operating systems, the rpcinfo command reports RPC information.

Description

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. The 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.

The version number is required for -b and -d options.

Syntax

rpcinfo [-m | -s ] [ host ]

rpcinfo -p [ host ]

rpcinfo -T transport host prognum [ versnum ]

rpcinfo -l [ -T transport ] host prognum versnum

rpcinfo [ -n portnum ] -u host prognum [ versnum ]

rpcinfo [ -n portnum ] -t host prognum [ versnum ]

rpcinfo -a serv_address -T transport prognum [ versnum ]

rpcinfo -b [ -T transport ] prognum versnum

rpcinfo -d [ -T transport ] prognum versnum

Options

Examples

rpcinfo

Display all of the RPC services of the local host.

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.

rpcinfo cpuhope

Show all RPC services registered with rpcbind on the machine named cpuhope.

rpcinfo -s cpuhope

Same as the above command, but shows more concise information (the default information display can be quite lengthy). Output resembles the following:

program version netid service owner 100000 2,3,4 local,tcp,udp,tcp6,udp6 rpcbind super-user 100008 1 udp,tcp,udp6,tcp6 walld super-user 100002 2,1 udp,udp6 rusersd super-user 100001 2,3,4 udp,udp6 rstatd super-user 100012 1 udp,tcp sprayd super-user 100007 3 udp,tcp ypbind super-user

rpcinfo -T tcp cpuhope prognum versnum

Show whether the RPC service with program number prognum and version versnum is registered on the machine named cpuhope for the transport tcp.

rpcinfo -p

Show all RPC services registered with version 2 of the rpcbind protocol on the local machine.

rpcinfo -d 100008 1

Delete the registration for version 1 of the walld (program number 100008) service for all transports.

rpcinfo -d walld 1

Same as the above example, but specifies walld by name.

netstat — Print information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships.
