Time for action – configuring your wireless card

We will be using the Alfa wireless card with the penetration tester's laptop.

Please follow these instructions step-by-step to set up your card:

Plug in the card to one of the BackTrack laptop's USB ports and boot it.
Once you log in, open a console terminal and type in iwconfig. Your screen should resemble as follows:
As you can see, wlan0 is the wireless interface created for the Alfa wireless card. Type in ifconfig wlan0 up to bring the interface up. Then type in ifconfig wlan0 to see the current state of the interface:
The MAC address 00:c0:ca:3e:bd:93 should match the MAC address written under your Alfa card. This is a quick check to ensure that you have enabled the correct interface.

What just happened?

BackTrack ships with all the required drivers for the Alfa card. As soon as the machine booted, the card was recognized and was assigned the network interface wlan0. By default, all network interfaces in BackTrack are disabled on boot. We enabled the interface using the ifconfig command. Now our Alfa card is up and functional!

Vivek Ramachandran

Vivek Ramachandran has been working on Wi-Fi security since 2003. He discovered the Caffe Latte attack and also broke WEP Cloaking, a WEP protection schema, publicly in 2007 at DEF CON. In 2011, he was the first to demonstrate how malware could use Wi-Fi to create backdoors, worms, and even botnets. Earlier, Vivek was one of the programmers of the 802.1x protocol and Port Security in Cisco's 6500 Catalyst series of switches, and he was also one of the winners of the Microsoft Security Shootout contest held in India among a reported 65,000 participants. He is best known in the hacker community as the founder of SecurityTube.net, where he routinely posts videos on Wi-Fi security, assembly language, exploitation techniques, and so on. SecurityTube.net receives over 100,000 unique visitors a month. Vivek's work on wireless security has been quoted in BBC Online, InfoWorld, MacWorld, The Register, IT World Canada, and so on. This year, he will speak or train at a number of security conferences, including Blackhat, DEF CON, Hacktivity, 44con, HITB-ML, BruCON Derbycon, Hashdays, SecurityZone, and SecurityByte.
