7.10 -> 8.04 - Lost Ethernet! (DNS ISSUE)
I just upgraded from 7.10 to 8.04, and promptly lost all connections to my LAN and the wider internet...
I have two nic cards: an onboard, eth0, and a netgear (GA311, maybe?) gigabit card, eth1. My network/internet comes to eth1. eth0 is currently unused.
manual network configuration displays both as set up with static IPs; however, when I attempt to access network-tools, and I click configure on either interface, I get:
Code:
The interface does not exist
check that it is correctly typed, and that it is correctly supported by your system
here are the results of "lshw -C network" and "sudo ifconfig&&iwconfig" :

any ideas?
Re: 7.10 -> 8.04 - Lost Ethernet!
first of all change either eth0 or eth1 to a different ip.. dont set both cards as 192.168.1.100 change one of them
Re: 7.10 -> 8.04 - Lost Ethernet!
I changed the ip address of eth0 to 192.168.1.212, then i ran "ifdown eth0" because I don't really need it. i gave eth1 an ifdown and ifup, but no change
lots of forums have asked for "dmesg | grep eth", so here it is:

still no connection... any other ideas?
Re: 7.10 -> 8.04 - Lost Ethernet!
the other weird thing is that my dd-wrt router (linksys wrt54gl) shows the computer as an "active client" which implies that the issue is not with the setup of the interface, but with the computer's use of said interface.
Re: 7.10 -> 8.04 - Lost Ethernet!
are you able to ping gateway? try ping google.com
Re: 7.10 -> 8.04 - Lost Ethernet!
ping just sits there, and times out... no responses... if i ping www.google.com or http://www.google.com, it tells me that they don't exist (or similar).
Re: 7.10 -> 8.04 - Lost Ethernet!
and are you able to ping your router?
Re: 7.10 -> 8.04 - Lost Ethernet!
can you post the output of
Re: 7.10 -> 8.04 - Lost Ethernet!
not able to ping router, am able to ping 127.0.0.1

Re: 7.10 -> 8.04 - Lost Ethernet!
hmmm, not sure if this will work, but lets take the netgear card out of the equation...focusing on just the onboard should be a bit less confusing.
First backup your /etc/network/interfaces file like this:
Code:
sudo cp /etc/network/interfaces /etc/network/interfaces.orig
Now open your /etc/network/interfaces file
Code:
sudo gedit /etc/network/interfaces
and comment out all lines except
Code:
auto lo
iface lo inet loopback
save, restart, cross fingers, your eth should automatically get an ip...if it doesn't work you can restore original interfaces file with
Code:
sudo cp /etc/network/interfaces.orig /etc/network/interfaces
