Hey everyone, I don't consider myself to be a total newbie, I've been using all sorts of *nix builds for the last 6 years or so, but finally I've hit a retarded problem that I can't figure out, and I can't find the answer anywhere.
I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side. In Lucid I can ping my router, and the network manager says I'm good to go, but I can't get to any web sites. It all started when I tried to put my laptop on another network by mimicking the settings of a computer I had just unplugged from the network. MAC address and all. I have a feeling it might have to do with an unexpected MAC address somewhere, but I'm not sure
Below are posted all the relevant details I could think of for my network. Any help is GREATLY appreciate as I've been pounding my head against the wall for a week on this. (I'm set up using a static IP)
ifconfig eth0:
Code:
eth0 Link encap:Ethernet HWaddr 00:1f:16:ba:4c:8c
inet addr:10.136.9.147 Bcast:10.136.9.159 Mask:255.255.255.240
inet6 addr: fe80::21f:16ff:feba:4c8c/64 Scope:Link

collisions:0 txqueuelen:1000
RX bytes:44433 (44.4 KB) TX bytes:16428 (16.4 KB)
Interrupt:16
when I restart networking it sometimes says this:
Code:
root@jon-laptop:/home/jon# /etc/init.d/networking restart
* Reconfiguring network interfaces...
Ignoring unknown interface eth0=eth0.
[ OK ]
and sometimes says this:
Code:
root@jon-laptop:/home/jon# /etc/init.d/networking restart
* Reconfiguring network interfaces... [ OK ]
I haven't seen any rhyme or reason as to why sometimes it's one or the other.
dmesg | grep eth0 reveals this:
Code:
$ dmesg |grep eth0
