To verify that the Ethernet device is configured correctly, enter:
# ping curly
You should see: <hr>
# ping curly PING curly.my.domain. (192.168.1.1): 56 data bytes 64 bytes from 192.168.1.1: icmp_seq=0 ttl=255 time=0.219 ms 64 bytes from 192.168.1.1: icmp_seq=1 ttl=255 time=0.200 ms 64 bytes from 192.168.1.1: icmp_seq=2 ttl=255 time=0.187 ms [...]<hr> messages.
One important thing to look at in these two examples is that the names
(loopback and curly) correctly correlate to their IP addresses
(127.0.0.1 and 192.168.1.1). This verifies that the /etc/hosts files
is correct.
If the IP address for "curly" isn't 192.168.1.1 or the
address for "localhost" isn't 127.0.0.1, return to Section 3.4 and
review your entries in '/etc/hosts'.
If the names and addresses are indicated correctly in the result of the ping command but there are errors displayed then something is amiss with the interface configuration(s). Return to Section 3.1 and verify everything again.
If everything here checks out, proceed with the next section.
