Hi, everyone

I installed the Ubuntu 10.04 and couldn't connect the internet. There is not an eth0 or eth1 when I used ifconfig. It seems that the os lacks network card or drivers. I tried several ways but the problem is still not sovled. Any advice? Thanks in advance!

Why such an old version? We are at 14.04 right now, if I am correctly informed.

What's your hardware?
Anything in the message buffer? dmesg | grep eth or just dump it all out and find something NIC related.

Thanks for your reply. Firstly I used Ubtuntu 14.04 and got some problem during installation. Thus I changed to the previous version, which I am familiar with.

Hardware, Dell Desktop, 64bit. Sorry that I cannot remember the details, as it is not available at home. I will check the buffer and try the command.

What I know currently is that my computer do not support for the ethernet of Ubuntu. But it supports the ethernet card of RedHat. Under RHEL 6, the internet works normally. When I used ifconfig in Ubuntu, there is only lo. Thus I guess I need to install a new driver for the ethernet.

Thanks.

Check the message buffer under Red Hat. It should tell you the driver it uses.
Another way of finding the driver is going to /sys/class/net/eth0/device and ls -l driver. This is a symbolic link that contains the driver name. E.g. on my system (actually a virtual machine):
In this case, the driver is e1000.

By the way, there is a Ubuntu version between 14.04 and 10.04. Perhaps you have problems because your distro is comparatively old.

Hi, thanks. Actually, there is no eth0 folder under /net. I am thinking about try another version of ubuntu, as 10.04 really doesn't work well on my computer.

Anyway, thank you for your help.
