  • Wireguard and docker: providing VPN access to arbitrary containers

    Some containers just aren't meant to be connected directly to the internet. After all, you wouldn't want your ISP knowing which Linux distribution you download and share.

    If like me you have your BitTorrent client installed as a container on a homeserver to make sure it's always connected but you don't want to route your other containers through a VPN, you'll probably want to use a VPN-in-a-container and route your BitTorrent client through it.

    I already had a similar solution using OpenVPN but it was time for an upgrade. Oh yes, it's Wireguard time.

    As VPN provider, I use Mullvad.

  • Sort of making snapshots of UEFI libvirt-based virtual machines

    As of early 2022, one of the limitations of libvirt is that it doesn't support making snapshots of virtual machines that use UEFI instead of BIOS booting. Since various people want to get rid of BIOS booting, this is a problem on several levels. Fortunately it's possible to sort of get around this, in one of two ways; the difficult and I believe incomplete way that I haven't gotten working, and the easier way that I have. All of this assumes that you're using the normal QEMU/KVM backend for libvirt (which supports UEFI via OVMF).

  • 2022-04-22 regulating radiation

    One^wTwo days late for 4/20, I return to discuss equipment authorization. This is a direct followup to my last post about unlicensed radio. I apologize for my uncharacteristic decision to actually provide a promised follow-up in a prompt manner, and give you my assurances that it's unlikely to happen again. I will return to my usual pattern of saying "this is the beginning of a series" and then forgetting about the topic for two years.

    But equipment authorization is sort of an interesting topic, and moreover I think I really shortchanged the last post by not going into it. Because ISM bands and other so-called "Part 15" bands are unlicensed, the limitations that exist on usage of those bands stem pretty much entirely from the equipment authorization process. I also think I shortchanged the last post a bit by not providing some background on the regulatory structure, so here that goes first: [...]

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
