ifdown eth0; ifup eth0
Or as you said, /etc/init.d/networking restart usually works too.

  Greetings:
  How do I set up the networking in AGNULA/Demudi 1.2.1 ?
  I've installed the system on a second disk in my desktop system. I
 want to sh*tcan the 2.6.12 kernel asap, but I have no network
 connection. I fixed /etc/network/interfaces and can see eth0 in
 ifconfig's report, but where is the tool to configure the interface ??
 Best,

There's nothing remarkable about it. All one has to do is hit the
right keys at the right time and the instrument plays itself.
