Linux TCP/IP Settings

The instructions for setting up boot-time DHCP vary dramatically by distribution, so you may want to refer to your particular version’s documentation.

Note:

If you have more than one network card installed, you will need to pick distinct Ethernet identifiers for each (eth0, eth1, eth2, and so forth). If you select an identifier other than eth0 for your ADSL modem, use that identifier throughout.

RedHat

Edit or create /etc/sysconfig/network-scripts/ifcfg-eth0 so that it contains the following three lines:

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=dhcp

SuSE

Edit the file /etc/rc.config; search for the variables NETCONFIG, NETDEV_0, and IFCONFIG_0.

Set them as follows (see the instructions in rc.config):

NETCONFIG="_0"

NETDEV_0="eth0"

IFCONFIG_0="dhcpclient"

Reboot with this command: /sbin/shutdown -r now.

Debian

Add this line to the file /etc/network/interfaces:

iface eth0 inet dhcp

Reboot with this command: /sbin/shutdown -r now.
