This is a guide to the post-installation process, after connecting to a freshly-installed headless Kali Linux Raspberry Pi.

Post-Installation Procedure

The post-installation procedure that will be covered by the guide includes:

update and install software
set startup services
set configuration for programs

Change Your Password

Kali installations use a default password of "toor". Change this IMMEDIATELY. Use the passwd command.

Software Update

Kali uses aptitude as a software manager. Update all your packages, and upgrade your distribution:

apt-get update
apt-get -y dist-upgrade
apt-get install -y build-essential

Install Pi Toolbox

apt-get install -y vim
apt-get install -y tshark
apt-get install -y tcpdump

Python stuff to get pip onboard:

apt-get install -y python-dev
wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
python get-pip.py

Now "which pip" should return:

# which pip
/usr/local/bin/pip

Fix SSH Keys

OpenSSH server should be installed, but if it isn't:

apt-get install openssh-server

Remove any existing startup SSH service, and set the SSH service to run at SSH's default runlevel (that is, to run on boot):

update-rc.d -f ssh remove
update-rc.d -f ssh defaults

Next you will want to replace the default SSH keys provided on the SD card image. Move the old SSH keys somewhere else:

cd /etc/ssh/
mkdir insecure_original_default_kali_keys
mv ssh_host_* insecure_original_default_kali_keys/

And finally, make new SSH keys for this machine.

dpkg-reconfigure openssh-server

Non-Root User

Disable the ability to SSH as root, reducing risk of hijacking. (You did change the default root password, didn't you?) Make a non-root user who can sudo:

useradd charles
adduser charles sudo

Print info:

id charles

Next, disable root login via SSH.
