Falko, For the perfect setup (Debian Sarge) on page 3 you've explained to add some nameservers, which are needed to resolve domain names. However, you did not mention to add nameservers within the perfect setup (Debian Etch). I don't understand this. Is there a particular reason for this?
If you're using DHCP, then some valid nameserver should have got added to /etc/resolv.conf during the initial installation, so there's no need to modify /etc/resolv.conf.
