Applying updates and configuring extra security tools in Backtrack
In this recipe, we
will cover the process of updating BackTrack and configuring some extra tools,
which will be useful in later chapters and recipes. As BackTrack 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 dive into updating our installation, obtaining an activation code for
Nessus, and concluding with installing Squid.
How to do it...
Let's begin the process of applying updates and configuring extra
security tools:
1. Update the local
package index with the latest changes made in the repositories:
apt-get update
2. Upgrade existing packages:
apt-get upgrade
3. Upgrade to the new
version (if available):
apt-get dist-upgrade
4. Obtain an activation
code for Nessus by registering at the following website:
http://www.nessus.org/products/nessus/nessus-plugins/obtain-an-activation-code
5. 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.
6. Create a user account
for the Nessus web interface:
/opt/nessus/sbin/nessus-adduser
7. To start the Nessus
server, we simply invoke the following command:
/etc/init.d/nessusd
start
8. Install Squid:
apt-get install squid3
9. Remove Squid from
starting up automatically at boot time:
update-rc.d
-f squid3 remove
