Prerequisites

install ansible: apt-get install -y ansible

add hosts lines to ansible: echo "[thismachine]" >> /etc/ansible/hosts echo "127.0.0.1" >> /etc/ansible/hosts

Setup

you have to change at least 2 variables:

• users
• hostname

which by default are set to "CHANGEME" anche the playbook is set to fail if these are set to CHANGEME

insert your user in: variables.yml in the list: users: goofy and their ssh keys in the folder keys in form of filename: goofy.key.pub and format: ssh-rsa [/CUT] user@host

insert your hostname in variables.yml in the variable: hostname:

Run defaults

ansible-playbook common.yml

this playbok will:

• check if the variables are set
• change the hostname to the one that has been set in the variables
• set the timezone to the one in the variables (default: Europe/Rome)
• update repositories
• install base packages
• retrieve the main network interface (the one that is associated with the default gateway)
• iptables:
  • create the users defined in the variables with the keys
  • create basic ipv4 rules
  • create blocking ipv6 rules
  • apply said rules in iptables-persistent
• fix bashrc how I like it
• harden ssh
