I need to run sudo dhclient eth0 every time I unplug and plug the Ethernet back in.

This is pretty annoying! How can I fix it?

You should check your network configuration in:


If you want DHCP it should be something like this:

auto eth0
iface eth0 inet dhcp

If you want a static IP it should go like this:

auto eth0
iface eth0 inet static

You can read this too.
