Default Live CD internet connection issue

Hi,

Though I am new to Ubuntu, but frankly speaking have liked it to a great extent and that's why thinking of even learning it. But in my friend's system, when he was having Vista, it got corrupted, the system is not getting booted! Now, when I used Ubuntu LTS 10.04 CD (Live Mode), everything was okay except that Internet was not getting connected. Please let me know how do I accomplish this? I understand that Ubuntu auto detects the settings (like it did in my PC and auto detected the broadband Internet connection), it is not going so there. In Auto eth0 everything is correct like I did for my PC but there its not working.


Any help would highly be appreciated. Please let me know regarding this.

Is the PC using wireless or a wired connection?

Only wired connection.

OK - let's see what it currently has configured. Post the output of 'ifconfig -a'

OK - let's see what it currently has configured. Post the output of 'ifconfig -a'


Here is the output:



ubuntu@ubuntu:~$ ifconfig -a

But the main concern is that when I was trying Ubuntu 10.04 LTS in my system, I just entered the email addess (192.168.1.11) with DNS server, netamask and gateway only from the icon in the system tray and it started working but now its not working! amaing!

This shows that the eth0 interface has no ip address associated with it, nor does it have a default gateway. It hasn't actually been configured.
If you want to configure this interface manually, then enter the following in /etc/network/interfaces (feel free to adjust the IP addresses to suit your network set-up - you mention that you use 192.168.1.11 as the gateway, so I've used the same value).






auto eth0
iface eth0 inet static
address 192.168.1.50
netmask 255.255.255.0
network 192.168.1.11
broadcast 192.168.1.255
gateway 192.168.1.11
*Alternatively, you may prefer to configure this interface up to use DHCP and have the router hand out ip addresses - your choice.
