22 January 2026

In the previous post of the Home NAS on FreeBSD setup series, we got acquainted with restic – a utility for working with backups that supports encryption, snapshots, and change history; see FreeBSD: Home NAS, part 8 – backup of NFS and Samba data with restic. However, in addition to archival data in S3, I… Read More: FreeBSD: Home NAS, part 9 – data backup to AWS… »

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… »

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… »

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… »

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… »

29 December 2025

It is time to tidy up SSH on FreeBSD itself and on the clients – laptops running Arch Linux, as I am still using password authentication on my home machines. Actually, the settings described below are specific neither to FreeBSD nor to Linux, as the SSH server is the same on all systems (OpenSSH_9.9p2 on… Read More: SSH: sshd hardening on FreeBSD and Linux, and 1Password integration4… »

Problems with upgrades on Arch Linux are very rare, and a situation like today’s is a first for me in nearly 10 years of using the system. So, what happened: installed upgrades with pacman -Syu after installation, sudo reboot would hang managed to reboot only with sudo reboot -f (force) after the reboot – X.Org… Read More: Arch Linux: pacman -Syu and “Failed to connect to system… »

Continuing the setup of my home NAS on FreeBSD. Actually, a NAS is a Network System, and it’s desirable to have access to it from other devices – Linux and Windows hosts, phones, and TVs. Here we have two main options – Samba and NFS. One could also mention sshfs – but this solution is… Read More: FreeBSD: Home NAS, part 6 – Samba server and client… »

26 December 2025

In the previous post, FreeBSD: WireGuard VPN, Linux peer and routing between networks, we set up a VPN to connect two networks – my office and home – and everything is working perfectly. However, currently, to connect to any host in the networks, you have to specify an IP address. Of course, you could manually… Read More: FreeBSD: Home NAS, part 4 – Local DNS with Unbound5… »
