  • Understanding a thing with ZFS on Linux, kernel versions, RPMs, and DKMS

    I use ZFS on Linux on my office and home Fedora desktops. It's installed with RPM packages using the 'zfs-dkms' option, where the ZoL RPMs install a DKMS module that DKMS then builds for whatever kernels. The advantage of the DKMS approach is that I don't need to somehow pre-build new kernel module RPMs before I upgrade my kernel; instead DKMS rebuilds things automatically. Recently I went to install a Fedora kernel upgrade to 5.16.11 and as part of the upgrade DNF said it was going to remove the 'zfs' and 'zfs-dkms' RPMs as incompatible. Of course I said no to that, and when I looked at the 'META' source file that controls kernel version compatibility (among other things) I saw that ZoL currently only supports up to 5.15.

  • On overwriting disks

    When overwriting disks with little storage capacity, the lack of progress bar isn’t a pressing issue because the operation doesn’t take a long time. For larger disks, an ETA proves invaluable. I like pv for this task.

  • Why self-host/use FLOSS?

  • Nftables - Demystifying IPsec expressions

    In this article I like to take a look at the expressions provided by Nftables for matching IPsec-related network packets. The common situation is that you need to distinguish packets from normal traffic, which either have been received through a VPN tunnel and already have been decrypted or packets which are to be sent out on a VPN tunnel, but have not been encrypted yet. Those kind of packets can be matched by these expressions within packet filtering rules. I'll explain how these expressions work, what they use as back-end, what their limitations are and how you can use them to get your intended behavior. Further, I take a short glimpse at the Iptables equivalent of these expressions.

  • 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.
