Hello Here is a script modification for /etc/init.d/networking in Debian so that your list of network interfaces can be reconfigured during boot. Why would you like to have a script like this? Well, in my case, I have a laptop with a lan based eth0 and a wifi based eth1. If I am not connected to a lan during boot, I have to wait for the network interface on eth0 to time out with its dhcp request. With this script, it displays the current network config and gives me a chance to modify it.
Here is an example of the script running: bic:~# /etc/init.d/networking restart Current interfaces: auto lo eth1 Customize networking y Enter interfaces besides lo. eth0 lo eth0 New interfaces are: auto lo eth0 * /etc/network/options is deprecated. Setting up IP spoofing protection...done (rp_filter).
