In-Depth Information
This concludes our Kismet crash course. We'll cover how to analyze the captured
network traffic that we logged to
~/kismetlogs
later, in the
Analyzing packet dumps
with Wireshark
section.
Mapping out your network with Nmap
While Kismet gave us a broad overview of the Wi-Fi airspace around your home,
it's time to get an insider's perspective of what your network looks like.
For the rest of this chapter, you can stay associated with your access point or
connected to your router via Ethernet as usual. You'll need to revert any changes
you made to the
/etc/network/interfaces
and
/etc/default/ifplugd
iles
earlier during the Kismet section. Then reboot your Pi and check that you are indeed
associated with your access point using the
iwconfig
command.
Wi-Fi adapter associated with the MiFi access point
We'll be using the highly versatile
Nmap
application to gather information about
everything that lives on your network. Let's install Nmap together with two other
packages that will come in handy:
pi@raspberrypi ~ $ sudo apt-get install nmap xsltproc elinks
Nmap as well as the other applications we'll be using in this chapter will want to
know what IP address or range of addresses to focus their attention on. Nmap will
gladly start scanning the entire Internet if you tell it to, but that's neither practical nor
helpful to you or the Internet. What you want to do is pick a range from the private
IPv4 address space that is in use on your home network.
