ChorusOS 4.0 Network Administration Guide

netstat

netstat(1CC) displays information about network-related data structures, such as network interfaces (use the -i option) and routing tables (use the -r) option. The utility is available both as a C_INIT(1M) built-in command, and as a standalone actor that supports a wider range of options.

Example 6-3 Displaying Network Statistics with netstat

The following example uses the built-in version of netstat to view information about network interfaces and routing tables.


$ rsh target netstat -i

Note that in order for the built-in version to function, you must set the ADMIN_NETSTAT feature to true and rebuild the ChorusOS system image.

netstat is also available as a stand-alone actor, /bin/netstat.r.
