The Destek Group, Inc.
>Environment:
This has been tested on 3.1-RELEASE and 3.2-RELEASE running
gated.
>Description:
Basicly runnign netstat -c is a faster version of
netstat -rn|wc. -c follows about the same code path as
-rn does but -c only outputs the total number of routes
in each type(IP/appletak ect...)
