First, install the necesssary packages:

% apt-get install libpam-oath oathtool

Generate a key and write it to /etc/users.oath (NB the key will be in hexadecimal; if you are using Authy you will want to convert it to BASE32):

% KEY=$( head -c 1024 /dev/urandom | openssl sha1 | awk '{ print $2 }' )
% echo "HOTP/T30/6 andrewlkho - ${KEY}" >> /etc/security/users.oath
% chmod 600 /etc/users.oath

What is this all about?

This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.

Problème d'ouvertue de port non désirée sur une configuration IPTABLES

Un problème de contournement des règles iptables fixées par utilisateur peut survenir avec l’utilisation de règles iptables RELATED,ESTABLISH trop générique et le chargement de helper de service non présent ou non utilisé sur la machine (exemple FTP actif, SIP, IRC …).

True fact: Mon server MariaDB s'est fait attaqué comme ça alors que le port dans l'iptable n'était pas ouvert.
