    In this article I’ll set up the sudo system on Debian. By default the Debian installer only sets up sudo if you don’t supply a root password at install time. You don’t need sudo on a machine to to use it effectively and I have used Debian machines without it for years. The problem is…

    Today I’ll be looking at the Proxmox firewall and what to do about container and VM firewalls. Out of the box Proxmox comes with a firewall installed but not activated. At a minimum you should probably activate the Proxmox firewall for the cluster but it’s up to you how you protect the containers and VM’s…

    In this article I’ll be installing Pi-Hole on Proxmox. Pi-Hole is a DNS sinkhole or blackhole that can effectively block ads and other unwanted content. It works by replacing your usual DNS server with Pi-Hole and then dishing up non-routable addresses for unwanted content based on a block list. In this article we’ll be installing…

    A while back I wrote a post on routing all traffic through a VPN under Linux. The solution discussed in that post is fine if you are only dealing with regular applications but when you are dealing with containers the world is a difference place. Docker networks are, or at least can be, complicated. By…

    I’ve recently been setting up a machine that has to send all data over a VPN which feels like it should be really simple but has actually turned out to be tougher than I expected. I thought I could set it up by using routing and I think it’s probably possible but way more hassle…
