This encompasses the various things I do whenever I’m setting up a new Kali VM in Virtualbox.

Proxy Configuration

Configure proxy (if applicable) by inputting the required values into /etc/environment. It will probably look something like this:

http_proxy=www.proxy.com:80
https_proxy=www.proxy.com:80
no_proxy=.proxy.com,localhost,127.0.0.1

Resource: https://askubuntu.com/questions/175172/how-do-i-configure-proxies-without-gui

Config apt with proxy (if applicable): touch /etc/apt/apt.conf.d/95proxies

Input the required values into this file. It will probably look something like this:

Acquire::http::proxy "http://www.proxy.com:80";
Acquire::https::proxy "http://www.proxy.com:80";
Acquire::ftp::proxy "http://www.proxy.com:80";

Restart the server : reboot

Welcome back, your proxy should be working now. Celebrate by taking a snapshot.

Install all of the updates

This will get you the latest and greatest:

apt update
apt upgrade -y
apt dist-upgrade -y

Install the VirtualBox Guest Additions:

apt update
apt install -y virtualbox-guest-x11

Install the linux headers:

uname -r
apt install -y linux-headers-*
reboot

Take a snapshot.

Install docker

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
echo 'deb https://download.docker.com/linux/debian stretch stable' > /etc/apt/sources.list.d/docker.list
apt update
apt install -y docker-ce

Start docker automatically upon reboot:

systemctl enable docker

Configure docker with proxy

mkdir /etc/systemd/system/docker.service.d
touch /etc/systemd/system/docker.service.d/http-proxy.conf

Setup docker with the proxy by inputting the required values into /etc/systemd/system/docker.service.d/http-proxy.conf. It will probably look something like this:

[Service]
Environment="HTTP_PROXY=http://www.proxy.com:80/"

Restart the server : reboot

Take a snapshot.

At this point, if you need to install any certs in your browser or configure your browser to work with your proxy, follow the instructions provided by your corporate IT provider.

Install firefox addons that you need like foxyproxy.

Test it:

Install Ansible

bash -c "$(wget https://raw.githubusercontent.com/l50/bash-scripts/master/install_ansible.sh -O -)"

Fix for invalid signature on update

This means you haven’t updated for a while, and that’s very bad. You should really be updating. However, if you run apt update and get an invalid signature error, run this command: wget -q -O - https://archive.kali.org/archive-key.asc | apt-key add
