View Full Version : [ubuntu] Loopback interface not on startup

Hi !

I own an Ubuntu Server 9.04 on a remote dedicated server. Since a few days (?) the loopback interface is not 'up' on reboot : I only have eth0 (which works fine).

Here is my /etc/networking/interfaces (did not change since server initialization):

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

#eth0 is enabled by initrd
auto eth0:0
iface eth0:0 inet static
address xx.xx.xx.xx (censured)

As root, I only have to do a 'ifconfig lo up' to make it work.

Does anybody have any idea why this interface does not show up on boot ?

Nobody ?

I presume that's /etc/network/interfaces.
Nothing really obvious jumps out as a problem.

Thank you for your reply.

Ok, so I'll add a "ifconfig lo up" in /etc/rc.local

Can you confirm that it is the right place to put this command ?
