I have a backup server which by accident i changed the /etc/network/interfaces file to look like: Code: (.....first part untouched) # the network card auto eth0 iface eth0 inet dhcp (I was convinced I was working on another machine : kvm switch are helpfull but deadly as well) So with midnight commander i have retyped the whole file according the perfect setup debian (checked it over and over by the letter) and I get this error when I run /etc/init.d/networking restart: Code: Setting up IP spoofing protection: rp_filter. Reconfiguring network interfaces...ifup: interface lo allready configured Don't seem to have all the variables for etho/inet. Failed to bring up eth0. I can't find anything in the log files which helps me does somebody have a clue ? thanks in advance
Found a similar file (from a system image) modified and pasted it: it works now Its solved: cpoied a file from the machine which was the image of the mainserver. It works now so it must have been a typo Still didn't figure out what it was but the again it works now thanks
