To verify that the Ethernet interface is up and running, issue ifconfig to check
the status of the Ethernet interface. It is possible to use netstat -i to check
the statistics on the Ethernet interface. For information on ifconfig and
netstat, see Chapter 7 Linux Driver Software.
Ping an IP host on the network to verify connection has been established.
From the command line, issue the ping <IP address> command, and then
press ENTER.
The ping statistics that are displayed indicate whether or not the network
connection is working.
