Network configuration
~~~~~~~~~~~~~~~~~~~~~
loopback devices
^^^^^^^^^^^^^^^^
Example for loopback device configuration:
---------------------
auto lo
iface lo inet loopback
---------------------
static network configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Example for an ethernet network card:
---------------------
auto eth0
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0
broadcast +
gateway 192.168.1.254
---------------------
The DNS resolver must be manually configured in /etc/resolv.conf.
The plus for the broadcast value, will calculate the correct broadcast address for the network.
dynamic network configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Example for an ethernet network card:
---------------------
auto eth0
iface eth0 inet dhcp
---------------------
bridge configuration
^^^^^^^^^^^^^^^^^^^^
Example for a network bridge with two ethernet network interfaces and an ip address:
---------------------
auto br0
iface br0 inet static
address 192.168.99.1
netmask 255.255.255.0
broadcast +
bridge-ports eth0 eth1
---------------------
Just a bridge without an ip address:
---------------------
auto br0
iface br0 inet manual
bridge-ports eth0 eth1
---------------------
You need to install either Busybox brctl applet or the bridge-utils package. The required kernel modules will be automatically selected.
VLAN network interfaces
^^^^^^^^^^^^^^^^^^^^^^^
Example configuration of a network interface with VLAN ID 8 without any ip configuration:
---------------------
auto eth0.8
iface eth0.8 inet manual
---------------------
You need to install Busybox vconfig applet. The required kernel modules will be automatically selected.
PPP over Ethernet
^^^^^^^^^^^^^^^^^
Typical DSL configuration:
---------------------
auto ppp0
iface ppp0 inet ppp
use-template pppoe
provider isp
ppp-mtu 1412
ppp-username foo
ppp-password bar
ppp-device eth1
---------------------
The provider can be used as argument for "pon" and "poff" commands.
You need to install the ppp and ppp-mod-pppoe package. The required kernel modules will be automatically selected.
wireless client configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Example wireless client configuration, secured with WPA2:
---------------------
auto wlan0
iface wlan0 inet dhcp
wireless-ssid myap
wireless-channel 11
wireless-mode sta
wireless-security wpa2
wireless-passphrase xxxxxx
---------------------
You need to install iw and wpa_supplicant packages. For older wireless drivers you
need to install wireless-tools instead of iw and use the following variable to choose the right tools:
---------------------
wireless-extension 1
---------------------
wireless accesspoint configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To configure an access point use following example:
---------------------
auto wlan0
iface wlan0 inet static
address 192.168.40.10
netmask 255.255.255.0
broadcast +
wireless-ssid myap
wireless-channel 8
wireless-mode ap
wireless-security wpa2
wireless-passphrase xxxxxx
---------------------
You need to install hostapd and iw/wireless-tools packages.
hso umts modem
^^^^^^^^^^^^^^
If you have a HSO UMTS modem, you can use following to configure internet access:
---------------------
auto hso0
iface hso0 inet manual
pin 1234
apn your.apn
---------------------
ATM configuration
^^^^^^^^^^^^^^^^^
For example a configuration on a Linksys AG241 router with integrated DSL modem,
you can configure two ATM devices to distinguish between Internet and IPTV traffic:
---------------------
auto eth0.1
iface eth0.1 inet manual
auto eth0.8
iface eth0.8 inet manual
auto nas0
iface nas0 inet manual
auto nas1
iface nas1 inet manual
atm-vpi 1
atm-vci 34
auto br0
iface br0 inet manual
bridge-ports eth0.1 nas0
auto br1
iface br1 inet manual
bridge-ports eth0.8 nas1
---------------------
More network setups can be implemented on request.
