VIPER / VIPER-Lite Embedded Linux Development Kit Quickstart Arcom Embedded Linux (AEL)

Setting up networking

As supplied, the board uses the DHCP protocol to configure the network. This requires

a DHCP server to be available on your network. For more information, please consult

your network administrator.

To configure the VIPER / VIPER-Lite to use a static IP address, follow these steps:

1 Log in to the VIPER / VIPER-Lite by entering the following log in details:

Password: arcom

2 Edit the file /etc/network/interfaces using the nano editor.

# nano /etc/network/interfaces

The vi editor is also installed, in case you prefer to use this.

3 Modify the iface eth0 inet dhcp line to look like the following (substituting your

own IP address and netmask):

iface eth0 inet static

address 10.7.28.2

netmask 255.255.0.0

gateway 10.7.1.1

4 Save the file by holding down Ctrl and pressing O.

5 Exit by holding down Ctrl and pressing X.

6 Optional. Set up a Domain Name System (DNS) server if required. You need a

DNS server if you want to use domain names (such as www.arcom.com) when

accessing the Internet.

To set up a DNS server, edit the file /etc/resolv.conf and add your DNS server

address as follows:

nameserver 10.7.1.9

7 Reinitialize the networking by typing:

# /etc/init.d/networking restart

The following is displayed:

Reconfiguring network interfaces...done

For standalone systems where the VIPER / VIPER-Lite is connected directly to the host

system through an Ethernet crossover cable, you can modify the settings of the VIPER /

VIPER-Lite and the host system, similar to the example shown above, to set up a

network between them.

Chapters 25 and 26 of the RUTE Manual provide a useful introduction to TCP/IP

networking. This manual is on the Development Kit CD, in the /manuals/ folder.
