AWS: Amazon Linux – Sending Email with Postfix via Gmail
0 (0)

16 March 2026

Continuing the setup of the new RTFM server. The next step is configuring the ability to send mail from EC2, since both important messages for the root user and RTFM itself need to send emails. I was thinking of using AWS Simple Email Service – purely to refresh my memory on how to work with… Read More »

AWS: Self-Managed EC2 NAT Gateway vs AWS Managed NAT
0 (0)

15 March 2026

I looked at the costs for the infrastructure described in the previous post AWS: basic infrastructure setup for WordPress, and let out a heavy sigh: One NAT Gateway is a quarter of my AWS spend, and even with AWS Credits I can’t help feeling a bit stingy about it. There’s an option to remove the… Read More »

FreeBSD: Home NAS, Part 15: Automating Backups – scripts, rsync, rclone
0 (0)

15 March 2026

This is essentially the last major task – setting up automated backup creation. In the post FreeBSD: Home NAS, Part 13: Planning Data Storage and Backups I described the general idea in more detail – what gets backed up, where, what gets stored and how – and today is the purely technical part about the actual… Read More »

MikroTik: WireGuard VPN Setup and Linux Peer Configuration
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 »

FreeBSD: Home NAS, part 12: synchronizing data with Syncthing
0 (0)

14 March 2026

I’m gradually getting closer to wrapping up the home NAS setup on FreeBSD. There’s already a ZFS pool, datasets, and monitoring – time to start setting up backup automation. But what seemed pretty simple at first – “just copy the needed directories from the work laptop” – turned out to be an increasingly interesting problem… Read More »

13 March 2026

For those who don’t follow updates in the Telegram channel rtfmcoua or are visiting my blog for the first time, a reminder that for the last couple of months I’ve been building a “self-hosted home stack”, which already includes a couple of MikroTik devices and a ThinkCentre running FreeBSD. On the ThinkCentre / FreeBSD I… Read More »

Glance: setting up a self-hosted home page for your browser
0 (0)

13 March 2026

There’s this cool thing called self-hosted home pages. I saw them somewhere on Reddit a while back, saved them to bookmarks, and now that I have all this self-hosted stuff with NAS (see FreeBSD: Home NAS, part 1), Grafana, and other useful things for work and daily life – I thought it would be nice… Read More »

FreeBSD: Home NAS, part 14 – logs with VictoriaLogs and alerts with VMAlert
4.8 (5)

28 February 2026

A continuation of the home NAS setup series. Monitoring in general has already been configured in previous parts, but log management still needs to be set up – because doing it in the console with tail -f /var/log/messages is certainly possible – but there are more convenient tools available. We’ll use VictoriaLogs – especially since… Read More »
