6.3 Configuring Linux Wireless Security

In this section we will go through the steps involved in configuring a Linux system to operate on an encrypted WiFi wireless network. This is either a one or two step process depending on whether you already have an encrypted network to which you are adding a Linux system or whether you also need to configure your existing wireless network to use encyption.

6.3.1 Configuring the Wireless Base Station

If you have already followed the instruction in the user guide that came with your wireless base station to configure the network to use WEP encryption you can skip this step and move on to the next section. If you have not done so then the first thing to do is read the wireless base station user guide to find out how to configure the security features of the device. Such devices typically have a web interface that you can access from your web browser. The documentation will tell you the IP address to enter and this topic is covered in Chapter 2.

A typical web based configuration screen is shown if Figure 6.3 below. In this example a 128-bit encryption key has been entered.

For 64-bit encryption enter a 10 digit hexadecimal key and for 128-bit encryption enter a 26 digit hexadecimal key. Details of encryption and keys can be found in Section 6.1.
