There is an issue floating around since a year that affects proxmox users with a ZFS root partition, namely after an upgrade it sometimes won’t boot. See here or here for example. After it happening to me too (with two different servers) and familiarizing myself with the issue more closely, I came to the conclusion …
This is a follow up article to network-wide adblock with a Raspberry Pi the lazy. If you followed that article then the Raspberry (or equivalent) is already deeply integrated into your network, why not add it some other network related roles like for example VPN? Luckily there is a fully fledged OpenVPN based package in DietPi …

To protect your LAMP server against brute-force attacks you can use Fail2Ban. It’s a daemon that checks log files and does something if it finds a match according to it’s filters. In it’s simplest configuration it just bans (by adding an iptables rule) an IP address for a period of time. Let’s check it out how we can set it …
Building on my last experiences documented here (read that one first, please) in this tutorial we will set up a safe backdoor access that can wake up the target machine, send an SMS to confirm the source IP address and expect an SMS back.
