NOTA BENE

I've tested the playbooks mainly on Debian 9,10,11 and ubuntu (server) 18.04 LTS running as root, on Ubuntu (Desktop) 19.04 running ad user. I've started converting the roles to distinguish between OSes but it's incomplete.

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

or if you are running as non-root:

sudo 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

Run optionals

• docker.yml
  • installs docker-ce and docker-compose (variable in variables.yml for latest of docker-compose)
• lldp.yml
  • installs and enables LLDP
• telegraf.yml
• tincvpn.yml
• transmission.yml
• singularity.yml
  • installs go and builds and installs singularity
• tor.yml
  • installs tor base from tor repo

Versions

• docker-compose:
  • variable: compose_ver
  • look here: https://github.com/docker/compose/releases/latest
• go:
  • variable: singularity_go_ver
  • look here: https://golang.org/dl/ , the package is like go1.14.linux-amd64.tar.gz and you take the "1.14"
• singularity:
  • varaible: singularity_ver
  • look here: https://github.com/sylabs/singularity/releases/latest

Git push

git add --all
git commit -m "added things to readme"
git push -u origin master

or: git add --all && git commit -m "message" && git push -u origin master

TODO

• fix the installation that is only for deb systems in common.yml
• test on centos
