Mise à jour importante de log2ram du 2 octobre 2017
L'application log2ram est fort utile pour les amateurs du Raspberry Pi qui ont leur système sur une carte SD ou une clé USB.

Cette application va mettre en mémoire vive les journaux (logs) qui sont très régulièrement écrits par les logiciels que l'on utilise (en particulier si on a un serveur web, nextcloud, etc.).

Ces multiples écritures vont petit à petit "user" les cartes SD ou les clés USB et peuvent parfois réduire considérablement leur durée de vie.

Azlux, l'auteur de log2ram, a publié une mise à jour importante sur son github.

Il nous conseille vivement d'effectuer cette mise à jour !

Voici comment faire... proprement.

Et pour ceux qui n'utilisent pas encore log2ram avec leur Pi, c'est l'occasion de s'y mettre...

How To Protect SSH with Fail2Ban on Ubuntu 14.04
While connecting to your server through SSH can be very secure, the SSH daemon itself is a service that must be exposed to the internet to function properly. This comes with some inherent risk and creates a vector of attack for would-be assailants.

Any service that is exposed to the network is a potential target in this way. If you pay attention to application logs for these services, you will often see repeated, systematic login attempts that represent brute force attacks by users and bots alike.

A service called fail2ban can mitigate this problem by creating rules that can automatically alter your iptables firewall configuration based on a predefined number of unsuccessful login attempts. This will allow your server to respond to illegitimate access attempts without intervention from you.

In this guide, we'll cover how to install and use fail2ban on an Ubuntu 14.04 server.

Encryption in Nextcloud
Providing strong protection of data is the biggest benefit Nextcloud has over public clouds. Self-hosting means you are in control over your data. Of course, un-authorized access has to be stopped and this is where encryption comes in. In this blog post we’ll discuss the different types and layers of encryption used by Nextcloud to keep your data safe. We will discuss the threats the different kinds of encryption are designed to protect against, aiding system administrators in defining their threat model and taking the appropriate security measures.
