Check your interface config with "ifconfig".  Make sure you see eth0
with an IP address like this:

$ /sbin/ifconfig 
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
          RX packets:11542 errors:0 dropped:0 overruns:0 frame:0
          TX packets:11107 errors:0 dropped:0 overruns:0 carrier:11
          collisions:0 txqueuelen:100 
          RX bytes:6769940 (6.4 MiB)  TX bytes:865474 (845.1 KiB)
          Interrupt:3 Base address:0x300 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:931 errors:0 dropped:0 overruns:0 frame:0
          TX packets:931 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:305368 (298.2 KiB)  TX bytes:305368 (298.2 KiB)


If you don't see eth0, then you'll probably need to run dhcp to get
one.  I assume this since you mention DHCP.  You can run this using
either "pump" or "dhclient".  Try pump first, and if that doesn't
work, then try dhclient.  Verify the IP config with the ifconfig
command.  

Also, if you don't see eth0, perhaps it's not configured.  Make sure
your network cards is loaded.  You can check for the modules usling
"/sbin/lsmod".  You can also look in "/var/log/syslog"  (as root) for
indications that your network card has loaded properly.

This is a good start.  Let us know what happens.
