Then you YMMV. I mean, I don't know if that will interefere with Puppet 
:-?

When I'm inside a ssh session in my Lenny:

1/ Edit the "/etc/network/interfaces" file (don't change the IP of the 
host you're connected to, of course...)

2/ Run "/etc/init.d/networking restart && sleep 10 && ifup bond0 up

3/ Cross your fingers ;-)

Also, remember that if you want to manage the routing (e.g., the 
gateway), you better use route/ip commands that allow on-the-fly 
manipulation without disturbing the networking service.

If you are sitting in front of the server, yes. If you are connected 
remotely, use the above command.
