0 (0)

8 May 2026

In the post MikroTik: setting up WireGuard and connecting Linux peers I described how to set up MikroTik as a VPN Hub and connect a peer running on Debian Linux. Setup on Arch Linux is mostly the same as on Debian – but every time I end up digging through this blog and my other… Read More »

FreeBSD: Jails Networking and Container Management with Bastille
0 (0)

4 May 2026

Sometimes on FreeBSD you need to run services that aren’t officially supported by FreeBSD, and this post actually came about because I was installing Open WebUI on my NAS – and Open WebUI was easier to set up on Linux. So I spun it up in a FreeBSD Linux jail, and to create the container… Read More »

I run a bunch of web services on my home NAS – Grafana, VictoriaMetrics, my own WordPress blog, and half a dozen other small things. The whole series of posts on FreeBSD and NAS starts here – FreeBSD: Home NAS, part 1 – setting up ZFS mirror, there are 15 parts as of now. NGINX+PHP… Read More »

It’s time for a major server upgrade for RTFM, which I usually do by migrating to a new server – because I also do various other upgrades along the way, like upgrading the PHP version or even migrating to a different cloud.

0 (0)

14 March 2026

Another one of the many nice features of MikroTik – built-in WireGuard support (although even cheap TP-Link Archers have it). In my setup, the MikroTik RB4011 acts as a “VPN Hub” – all clients connect to it and are united into a single network, and the role of VPN is slightly exaggerated is genuinely important… Read More »

20 January 2026

For a couple of months now, my work laptop, a Lenovo ThinkPad T14 Gen 5 running Arch Linux, has been having trouble opening new websites – for the first 10-15 seconds, the site loads in “pieces”, for example: But then it “wakes up”, and everything starts working perfectly: Finally, when I started setting up a… Read More »
