If we want to use Kismet, we'll need to install it.
If it's already installed,
such as if you're using Kali Linux and most of its
configurations, we'll actually need to remove it.
So first,
just browse to the Kismet Wireless website and go to the
Downloads section. In the Downloads section, select the
Kismet package repositories.
Now from this page,
select the packages that go with the distribution you're using.
We're using Kali Linux, so I'll simply scroll down to the Kali Linux section.
And if you're using any other distribution,
feel free to scroll down to that distribution.
All we need to do from here is start by removing Kismet if it's installed,
which we'll do by using apt remove kismet, and then we need to copy
and paste these four commands in the terminal.
So I'll copy the first one, and I'll open a terminal.
Before I paste it, I'm doing apt remove kismet to be sure
that it is uninstalled. All right, it is uninstalled.
I'm pasting my clipboard,
and this will add the GPG key of the Kismet repository to my
apt. I'm simply going to continue and copy and paste these four
lines. And here we go, Kismet is installed. Now, Kismet is not
made to be executed as root, but it does create a group called Kismet,
so we need to add our user to that group to be sure we can run Kismet with
our own username without having to elevate privileges. So we'll do that
with usermod ‑a, to add, ‑G, a group, kismet,
which is the name of group, followed by g,
which is just my username, so replace that with your username.
Now that we've done that, we need to log out to be sure that everything is fine.
And in fact,
since it's a virtual machine we use only for this, I'm just going to reboot it.
Now that I've rebooted,
I'm simply going to try executing Kismet to see if it's installed properly.
It seems to be installed.
It is running,
even though there's no interface configured yet. So, our first
step installing Kismet has now completed.
