ifconfig is used to configure network interfaces. ifup reads /etc/networks/interfaces and do a bunch of things that would take a lot of ifconfigs and some other stuff. For example, my laptop has the following interfaces file # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) # The loopback interface # automatically added when upgrading auto lo iface lo inet loopback # The built in ethernet interface iface eth0 inet dhcp # PCMCIA card iface eth1 inet dhcp You probably want to change 'auto lo' to 'auto lo eth0' if you always want the dhcp address on startup.
