Arcom Embedded Linux Technical Manual Configuring AEL

Statically configuring an interface

The following options are valid for an IPV4 interface that is statically configured, using

the static method:

Option Description

address ADDRESS Address (dotted quad). Required.

netmask NETMASK Netmask (dotted quad). Required.

broadcast BROADCAST_ADDRESS Broadcast address (dotted quad).

network NETWORK_ADDRESS Network address (dotted quad).

gateway ADDRESS Default gateway (dotted quad).

For example, to configure eth0 to use the static address 192.168.1.4/24 with a default

gateway of 192.168.1.1, enter the following in /etc/network/interfaces:

iface eth0 inet static

address 192.168.1.4

netmask 255.255.255.0

gateway 192.168.1.1

Manually configuring an interface

The manual method causes no configuration. Such interfaces can be configured using

the up-* and down-* scripts.

Configuring an interface using DHCP

The DHCP method uses an installed DHCP client to obtain configuration information.

The hostname HOSTNAME option, which requests a specific hostname from the

server, is valid for an IPV4 interface configured using DHCP.

Automatically bringing up an interface on boot

A line in /etc/network/interfaces beginning with the auto keyword specifies interfaces

that should be brought up on boot. For example, to bring up the loopback (lo) and first

Ethernet (eth0) interfaces, include the following:

auto lo eth0

You can include as many auto lines as you like.

Hostname

The default hostname for a board is the board type. To change the hostname, edit the

file /etc/hostname.

You can use the command hostname to view the current hostname.
