rpcinfo Command

The rpcinfo command generates information about the RPC service that is running on a system. Use the following command syntaxes to display information about the RPC service:

# 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

Specifies the transport or protocol for the services

hostname

Specifies the host name of the server

progname

Specifies the name of the RPC program

For more information about the available options, see the rpcinfo (1M) man page.

If no value is given for hostname, the local host name is used. You can substitute the RPC program number for progname, but the name is more commonly used. 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:

• RPC program number

• Version number for a specific program

• Transport protocol in use

• Name of the RPC service

• Owner of the RPC service

The example shows information about the RPC services that are running on a server. The output that is generated by the command is filtered by the sort command by program number to make the information more readable. Several lines that list RPC services have been deleted from the example.

You can gather information about a particular RPC service by selecting a particular transport on a server. The following example checks the mountd service that is running over TCP.

# 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

The following example checks the NFS service that is running over UDP.

# rpcinfo -u bee nfs
program 100003 Version 2 ready and waiting
program 100003 Version 3 ready and waiting
