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: FreeBSD: Jails Networking and Container Management with Bastille0 (0) »

18 April 2026

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: SSL/TLS: Self-signed Certificate Authority for NGINX on FreeBSD0 (0) »

1 (1)

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: Amazon Linux – Sending Email with Postfix via Gmail1… »

AWS: Increasing the EBS volume size on an EC2 instance running Linux
0 (0)

16 March 2026

Every time I need to do this, I have to look it up, even though I’ve written about it somewhere before – but it was a long time ago: manually increasing the disk size on an AWS EC2. You get used to Kubernetes, where it’s enough to just change a value in a PersistentVolumeClaim, and… Read More: AWS: Increasing the EBS volume size on an EC2 instance… »

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: AWS: Self-Managed EC2 NAT Gateway vs AWS Managed NAT0 (0) »

FreeBSD: Home NAS, Part 13: Planning Data Storage and Backups
0 (0)

14 March 2026

When I was just starting to build my NAS and thinking about backups, everything seemed pretty simple: there’s a work laptop with data, there’s a FreeBSD server for the NAS – just take and copy the data. So the initial idea was to have backup script(s) on Linux hosts that would push data to the… Read More: FreeBSD: Home NAS, Part 13: Planning Data Storage and Backups0… »

Arch Linux: “mysterious” DNS timeouts and “in search of the Ethernet truth”
5 (1)

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: Arch Linux: “mysterious” DNS timeouts and “in search of the… »

FreeBSD: Home NAS, part 8 – NFS and Samba data backups using restic
4.2 (6)

5 January 2026

Actually, almost everything regarding my home NAS setup has been done – there is VPN access from various networks, different shares are available, and the security has been slightly tuned. Two main things remain: monitoring and backups. Having a ZFS mirror on two disks with regular ZFS snapshots is, of course, great, but it is… Read More: FreeBSD: Home NAS, part 8 – NFS and Samba data… »

FreeBSD: Home NAS, part 7 – NFSv4 and use with Linux clients
5 (2)

5 January 2026

The next step in the process of setting up a home NAS on FreeBSD is to add an NFS share. We set up Samba in the previous part – now we let’s add NFS shares to it. My idea is for the Samba share to be used for various media resources requiring access from phones… Read More: FreeBSD: Home NAS, part 7 – NFSv4 and use with… »

TCP/IP: SYN flood attack on the RTFM server, and “Hacker News hug of death”
0 (0)

2 January 2026

Got an alert from the monitoring system this morning, indicating that the blog is down: Well, I thought: another one DDoS, not the first time. Investigating the issue I went to the Cloudflare admin, enabled the Under Attack Mode, and started the investigation. Checked the requests: I think, okay, it’s simple – requests are coming… Read More: TCP/IP: SYN flood attack on the RTFM server, and “Hacker… »
