Now you can search for the package you’re looking for. Simply click 
the Search tab to open a search window. Because you are looking for Snort 
again, enter 
snort
into the search window and click Search. Scroll down the 
search results to find the package you’re looking for. Check the box next to 
snort and then click the Apply tab, as shown in Figure 4-3. Synaptic will now 
download and install Snort from the repository along with any necessary 
dependencies.

Installing Software with git
Sometimes the software you want isn’t available in any of the repositories—
especially if it’s brand new—but it may be available on github (https://www 
.github.com/), a site that allows developers to share their software with others 
to download, use, and provide feedback. For instance, if you want bluediv-
ing, a Bluetooth hacking and pentesting suite, and can’t find it in the Kali 
repository, you can search github for the software by entering bluediving 
into the search bar. If it exists on github, you should see the repository for 
it in the search results. 
Once you’ve found the software on github, you can install it from the 
terminal by entering the 
git clone
command followed by its github URL. 
For instance, bluediving is located at https://www.github.com/balle/bluediving 
.git. To clone it into your system, enter the command shown in Listing 4-7.
kali >git clone https://www.github.com/balle/bluediving.git

Listing 4-7: Cloning bluediving with git clone
The 
git clone
command copies all the data and files from that location 
onto your system. You can check to see that they’ve been successfully down-
loaded by using the long listing command 
ls –l
on the target directory, 
like so:
kali >ls -l
If you’ve successfully cloned bluediving to your system, you should see 
something like the following output:
total 80
drwxr-xr-x 7 root root 4096 Jan 10 22:19 bluediving
drwxr-xr-x 2 root root 4096 Dec 5 11:17 Desktop
drwxr-xr-x 2 root root 4096 Dec 5 11:17 Documents
drwxr-xr-x 2 root root 4096 Dec 5 11:17 Downloads
drwxr-xr-x 2 root root 4096 Dec 5 11:17 Music
--snip--
As you can see, bluediving has been successfully cloned to the system, 
and a new directory named bluediving has been created for its files.
Summary
In this chapter, you learned a few of the many ways to download and install 
new software on your Linux system. Software package managers (like apt), 
GUI-based installers, and git clones are the most common and crucial 
methods for an aspiring hacker to know. You’ll soon find yourself becom-
ing familiar with each of them.
