networking issues in Intrepid

[Christian]

Hi all,
I did not have to do this in Hardy and I am trying to find a solution to this.
If I don't have these lines in my /etc/network/interfaces file it doesn't work:
auto lo eth0
iface lo inet loopback
iface eth0 inet dynamic
I then need to run the dhclient command each time after I reboot the system. Then everything is working fine. As I said, I didn't have to do this in Hardy.
Any ideas?
Best regards and thanks,
Christian
