I have upgraded 8.10 to 9.04 I can not get it to recognize eth0 it says the interface does not exist when, in networking tools, I push the radio button to configure.How can I resolve this? I have tried the help menu
Those numbers sound like buntu. Is that correct? Remember we can not see your machine, so you need to tell us the details.
Open a command prompt and run the command 'sudo ifconfig eth0 up' You will need the root password. Do not enter the quotes, just what is between them. Post the results. We'll go from there.

I do have ubuntu and I tried sudo ifconfig eth0 and it reported once, the second time I tried to run it it could not find ifconfig.I have sent for a new disk with the newest kubuntu distro. hopefully I can load it over ubuntu 9.04 My thought is to put my computer on ice till I can reinstall a newer distro and see if this fixes it.might have some kind of a bug! Thanks for the help. Brian

The binary for ifconfig is usually in /sbin/ directory. As a regular user /sbin is probably not in your path.
This can be changed, by modifying your path, or the easy way is to prefix the command with the absolute path to the binary. ie. /sbin/ifconfig eth0 up; or what ever you want to do. You don't have a bug, you are not configured correctly.
As I asked above, post the results of '/sbin/ifconfig' ( without the quotes ). This will show the status of all interfaces on your system.
