To check your other network interfaces, give the netstat -in command. You see output similar to the following:
The second Ethernet connection is to the network 192.70.2, a different LAN from the first Ethernet connection. The address of the local station on the second LAN is 192.70.2.5. To check that connection, use the ping command to test the connection to another station on that network.Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
ec0 1500 192.70.0 192.70.0.9 15 0 15 0 24
ec1 1500 192.70.2 192.70.2.5 15 0 15 0 24

lo0 8304 loopback localhost 8101 0 8101 0 0
There is also a SLIP link running in this example. The SLIP link extends the same LAN as ec0
to another system in a different location. To test this link, find the hostname or IP address of the station at the other end of the SLIP link and use the ping command to test connectivity.
The lo0
interface is the loopback network interface on the local host.
