How do I get the network status?

Use the following netstat commands to get the network status:

netstat -in
List the interfaces, including the MAC and IP addresses that they've been configured with.
netstat -rn
Display the network routing tables that determine how the stack can reach another host. If there's no route to another host, you get a “no route to host” error.
netstat -an
List information about TCP/IP connections to or from your system. This includes the state of the connections or the amount of data pending on the connections. It also provides the IP addresses and ports of the local and remote ends of the connections.

For more information about netstat, see the Utilities Reference.
