rpcinfo Command
This command generates information about the RPC service that is running on a system. You can also use this command to change the RPC service. Many options are available with this command. See the rpcinfo(1M) man page. The following is a shortened synopsis for some of the options that you can use with the command.
rpcinfo [ -m | -s ] [ hostname ]
rpcinfo -T transport hostname [ progname ]
rpcinfo [ -t | -u ] [ hostname ] [ progname ]
- -m
-
Displays a table of statistics of the rpcbind operations
- -s
-
Displays a concise list of all registered RPC programs
- -T
-
Displays information about services that use specific transports or protocols
- -t
-
Probes the RPC programs that use TCP
- -u
-
Probes the RPC programs that use UDP
- transport
-
Selects the transport or protocol for the services
- hostname
-
Selects the host name of the server that you need information from
- progname
-
Selects the RPC program to gather information about
If no value is given for hostname, the local host name is used. You can substitute the RPC program number for progname, but many users can remember the name and not the number. You can use the -p option in place of the -s option on those systems that do not run the NFS version 3 software.
The data that is generated by this command can include the following:
-
The RPC program number
-
The version number for a specific program
-
The transport protocol that is being used
-
The name of the RPC service
-
The owner of the RPC service
The following example gathers information about the RPC services that are running on a server. The text that is generated by the command is filtered by the sort command to make the output more readable. Several lines that list RPC services have been deleted from the example.

The following two examples show how to gather information about a particular RPC service by selecting a particular transport on a server. The first example checks the mountd service that is running over TCP. The second example checks the NFS service that is running over UDP.
% rpcinfo -t bee mountd program 100005 version 1 ready and waiting program 100005 version 2 ready and waiting program 100005 version 3 ready and waiting % rpcinfo -u bee nfs program 100003 version 2 ready and waiting program 100003 version 3 ready and waiting |
