The syslog will show the details of the dhcp process, your system
getting it's IP configuration. That's all it'll show. If you're not
sure your network is working, check to make sure eth0 is configured
properly by checking "ifconfig eth0" as root, and then ping the
address shown:
$ sudo ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:A0:C9:BC:78:C9
inet addr:192.168.0.116 Bcast:192.168.0.255
Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

collisions:0 txqueuelen:100
RX bytes:823076 (803.7 KiB) TX bytes:292453 (285.5 KiB)

$ ping -c 2 192.168.0.116
PING 192.168.0.116 (192.168.0.116): 56 data bytes
64 bytes from 192.168.0.116: icmp_seq=0 ttl=64 time=0.5 ms
64 bytes from 192.168.0.116: icmp_seq=1 ttl=64 time=0.4 ms
If that works, then check to see if you received a default gateway
from dhcp:
$ netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 40 0 0 eth0
0.0.0.0 192.168.0.1 0.0.0.0 UG 40 0 0 eth0
The "0.0.0.0" is the default gateway. See if you can ping it:
$ ping -c 2 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: icmp_seq=0 ttl=255 time=0.8 ms
64 bytes from 192.168.0.1: icmp_seq=1 ttl=255 time=1.2 ms
Now, lets see if your DNS is working. First check to see if it got
configured:
$ cat /etc/resolv.conf
search attbi.com
nameserver 216.148.227.68
nameserver 204.127.202.4
Now see if you can reach one:
$ ping -c 2 216.148.227.68
PING 216.148.227.68 (216.148.227.68): 56 data bytes
64 bytes from 216.148.227.68: icmp_seq=0 ttl=54 time=100.8 ms
64 bytes from 216.148.227.68: icmp_seq=1 ttl=54 time=79.6 ms
Okay, next find out if it will resolve for you:
$ nslookup -sil www.yahoo.com
Server: 216.148.227.68
Address: 216.148.227.68#53
Non-authoritative answer:
www.yahoo.com canonical name = www.yahoo.akadns.net.
Name: www.yahoo.akadns.net
Address: 64.58.76.178
Name: www.yahoo.akadns.net
Address: 64.58.76.179
<snipped the rest>
Try pinging one of the yahoo addresses. If that works, you're on the
internet. I'm assuming here that your service provider isn't
requiring you to use PPPoE/oA or the like. That would change the
interface you use for the above tests. It would be ppp0 instead.
