The Ethernet
interface (eth0), is assigned the IP address of 10.0.0.5. In this example, the eth0 has an IP
address of 10.0.0.5. Again, notice that the MAC address, which is a unique address related
to the Ethernet card hardware, is noted after the HWaddr indicator (00:0D:61:25:D4:17).
4. Communicate with another computer on the LAN. The ping command can be used to
send a packet to another computer and to ask for a packet in return. You can give ping
either a hostname (butch) or an IP address (10.0.0.10). For example, to ping a computer
on the network called butch, type the following command:
# ping butch
If the computer can be reached, the output will look similar to the following:
PING butch (10.0.0.10): 56(84) data bytes
64 bytes from butch (10.0.0.10): icmp_seq=1 ttl=255 time=0.351 ms

64 bytes from butch (10.0.0.10): icmp_seq=3 ttl=255 time=0.409 ms

64 bytes from butch (10.0.0.10): icmp_seq=8 ttl=255 time=0.384 ms
64 bytes from butch (10.
