Retry short limit:7 RTS thr:off Fragment thr:off Mode:Managed Access Point: Not-Associated Tx-Power=22 dBm The Alpha AWUS036NH WiFi device is actually device phy2 in the output above. The other two are using a USB driver, and are two USB WiFi devices that have been inserted.
The first one, listed as phy0, is the internal WiFi device of the computer. In the output above you can see there are 3 wireless devices. Phy2 wlan2 rt2800usb Ralink Technology, Corp. Phy1 wlan1 rt2800usb Ralink Technology, Corp. Phy0 wlan0 iwlwifi Intel Corporation Wireless 7260 (rev 73) Good tools for this purpose are airmon-ng and iwconfig: Once the Kali Live system has booted, investigate which wireless interfaces are available. A good overview of wireless devices and their capabilities can be found at. This particular WiFi USB device is capable of high transmit power, and also allows to be configured in so-called Master mode, allowing it to function as an Access Point, which we'll be using in future articles. A good and relatively cheap wireless interface is the Alpha AWUS036NH, which comes with a USB interface that can easily be plugged into any computer. The capabilities of a wireless device differ very much on the chipset used within a wireless device. Please note that not all wireless devices are the same. For purposes of using the AirCrack-ng tools, a good wireless interface is required. To prepare, start up a computer with the Kali Linux Live USB operating system.Īlso make sure that the computer has a functional wireless interface. We'll be looking at and using some of these tools in this article. One of those tool-sets is AirCrack-ng, which is a complete suite of tools to assess WiFi network security. Kali Linux, generally regarded as the de facto standard package of tools used to facilitate penetration testing to secure data and voice networks, comes with many pre-installed tools. In the first article we discussed setting up a Kali Linux Live USB environment for this purpose. For the purpose of this article, we'll be using Kali Linux. This article is all about WiFi security, and the ability of others to scan WiFi network information. This is the second article on the UNIX Health Check blog that discusses security awareness.
