rpcinfo

This command generates information about the RPC service running on a system. You can also use it to change the RPC service. There are many options available with this command (see the rpcinfo(1M) man page). This is a shortened synopsis for some of the options that you can use with the command:

rpcinfo [ -m | -s ] [ hostname ]

rpcinfo [ -t | -u ] [ hostname ] [ progname ]

where -m displays a table of statistics of the rpcbind operations, -s displays a concise list of all registered RPC programs, -t displays the RPC programs that use TCP, -u displays the RPC programs that use UDP, hostname selects the host name of the server you need information from, and progname selects the RPC program to gather information about. If no value is given for hostname, then the local host name is used. You can substitute the RPC program number for progname, but many users will 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 generated by this command can include:

Using the rpcinfo Command

This example gathers information on the RPC services running on a server. The text generated by the command is filtered by the sort command to make it more readable. Several lines listing RPC services have been deleted from the example.

This example shows how to gather information about a particular RPC service using a particular transport on a server.


% 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

The first example checks the mountd service running over TCP. The second example checks the NFS service running over UDP.
