Applying updates and configuring extra security tools

In this recipe, we will cover the process of updating Kali and configuring some extra tools which will be useful in later chapters and recipes. As Kali packages are constantly updated between releases, you will soon find that a newer set of tools are available than what were originally downloaded on your DVD ROM. We will start by updating our installation, obtaining an activation code for Nessus, and conclude by installing Squid.

How to do it...

Let's begin the process of applying updates and configuring extra security tools:

Update the local package index with the latest changes made in the repositories:
```
apt-get update
```
Upgrade the existing packages:
```
apt-get upgrade
```
Upgrade to the latest version (if available):
```
apt-get dist-upgrade
```
Obtain an activation code for Nessus by registering at http://www.nessus.org/products/nessus/nessus-plugins/obtain-an-activation-code.
Activate Nessus by executing the following command:
```
/opt/nessus/bin/nessus-fetch --register A60F-XXXX-XXXX-XXXX-0006
```
Where A60F-XXXX-XXXX-XXXX-0006 should be your activation code.
Create a user account for the Nessus web interface:
```
/opt/nessus/sbin/nessus-adduser
```
To start the Nessus server, we simply invoke the following command:
```
/etc/init.d/nessusd start
```
Install Squid:
```
apt-get install squid3
```
Prevent Squid from starting up automatically at boot time:
```
update-rc.d -f squid3 remove
```

Note

To find a particular package in the repository, we can use the following command after apt-get update:

apt-cache search <keyword>

Where <keyword> could be a package name or a regular expression.
