Notes for Configuring New Kali Hosts:

  1. Add a new non-root user.
  2. Set the user's password.
  3. Add that user to:
  • the sudo group.
  • the lpadmin group.
  1. Change default shell to bash.
  2. Login as that user and change the password.
  3. Update the host.
 useradd -m username
 passwd username
 usermod -a -G sudo username
 usermod -a -G lpadmin username
 chsh -s /bin/bash username

Now logout. Then login as username and change the password:

passwd username

Update the sources.list file to use https instead of http:

sudo vi /etc/apt/sources.list

Add deb https://mirrors.ocf.berkeley.edu/kali kali-rolling main non-free contrib to the sources.list file as well.

Update the host's software:

sudo apt update
sudo apt upgrade -y

or

sudo apt full-upgrade

then

sudo apt dist-upgrade
sudo apt autoremove

http Proxy Support

If you are in an environment isolated from the Internet via an http proxy:

Add this to /etc/bash.bashrc

function setproxy(){
        read -ep "Username: " proxusername
        read -esp "Password: " proxpassword
        encodedpassword=`echo -ne $proxpassword | hexdump -v -e '/1 "%02x"' | sed 's@\(..\)@%\1@g'`
        export http_proxy="http://$proxusername:[email protected]:80"
        export https_proxy="http://$proxusername:[email protected]:80"
        export ftp_proxy="http://$proxusername:[email protected]:80"
        }
function rmproxy(){
        unset http_proxy https_proxy ftp_proxy
        }
function lsproxy(){
        echo -e "$http_proxy\n$https_proxy\n$ftp_proxy"
        }

Add a 20proxy.conf file to help apt package manager understand how to contact the Kali repos:

vi /etc/apt/apt.conf.d/20proxy.conf

Then in that file:

Acquire {
  HTTP::proxy "http://user:[email protected]:port";
  HTTPS::proxy "http://user:[email protected]:port";
  }
