The arping application is a simple command that will allow you to ping devices by hostname, IP address, or MAC address. The unfortunate part is that most device will not respond to the arp requests, which are directed broadcast ICMP echo requests, though there are some out there that do. I go into more detail below regarding pinging via MAC address by providing an example of the typical output, example output when a MAC address responds to the ICMP echo requests, and details about how to configure hosts to respond to these ICMP echo requests. I also show a couple of the switches available with arping and provide examples of using arping to ping devices by IP and host.
Since I write a lot of articles about Backtrack Linux it is nice to have keyboard shortcuts for different screenshot commands. The two screenshot commands that I use most in Backtrack are “gnome-screenshot -w” and “gnome-screenshot”. The gnome-screenshot command will take a screenshot of the entire desktop while “gnome-screenshot -w” will take a screenshot of the active window only. Below I describe setting up keyboard shortcuts for each of these commands on Backtrack Linux. The below information will work the same on Ubuntu 10.04 as it does on Backtrack Linux since that is what the current Backtrack Linux version (Backtrack 5 release 3) is built on.
I recently wrote an article about how to fix btscanner in Backtrack Linux and realized after the article was completed that some people may prefer to launch btscanner via the menu in Backtrack Linux instead of the command terminal by typing btscanner. This article specifically explains how to add btscanner back to the menu in Backtrack Linux under Backtrack > Information Gathering > Wireless Analysis > BlueTooth Analysis > btscanner. The information could however apply to any tools you wanted to manually add to the Backtrack menu by modifying each variable accordingly.
I have been playing around with some of the bluetooth tools within Backtrack recently and btscanner is one of the main tools I have bene using. The btscanner application in Backtrack Linux provides two bluetooth scanning functions it calls inquiry scanning and brute force scanning. Unfortunately the package installed with Backtrack 5 release 3 will crash when attempting to use it for brute force scanning however I was able to create a fix that isn’t too messy to accomplish. Below we describe the btscanner crash in more detail and provide a way to get btscanner bluetooth brute forcing operating properly.
While doing some testing this evening I ran into all sorts of errors when attempting to compile a new version of btscanner on Backtrack Linux 5 R3. Luckily it is super easy to resolve the error complaining about an unrecognized command named -Wimplicit-function-dec. This error will display when attempting to run “make” against an already configured (./configure) btscanner source. Below we output the error in more detail, explain how to resolve the error by editing the make file, and then display the compilation process moving past the error.
