FreeBSD - A True Unix Way

Disk partitioning and filesystem management are among the most fundamental sysadmin skills.

This blog post is run-book how to deploy NGINX web server with Automatic TLS certificate issuance and renewal leveraging Let’s Encrypt DNS Challenge via Active24 DNS provider.

I need NFS 4.x storage for some tests.

ImpossibleCloud S3 storage is pretty interesting offering of European Object Storage.

Why vmx0, vmx1, vmx2 interface names sometimes cause fear?

I have multiple FreeBSD routers across my environments across the world each having its own WAN (Internet) connectivity and using WireGuard VPN to connect all into a private network.

The default FreeBSD configuration is optimized for compatibility, not maximum network throughput.

ZFS (Zettabyte File System) is a combined filesystem and volume manager, originally developed by Sun Microsystems for Solaris and now widely used on FreeBSD and other Unix-like systems.

MinIO is a high-performance, S3-compatible object storage platform designed for scalability, resilience, and simplicity in modern cloud-native environments.

FreeBSD is a free, open-source operating system based on the Berkeley Software Distribution (BSD), a branch of UNIX developed at the University of California, Berkeley.

SSH on my macOS Tahoe 26.1 uses cryptographic algorithm ssh-ed25519.

FreeBSD is great operating system to be used as router, firewall, and VPN concentrator.

FreeBSD manual installation from ISO is very simple and straight forward.

Smokeping is an open-source network latency monitoring tool created by Tobias Oetiker (the same author as MRTG).

On my FreeBSD routers I wan to run iperf as an always running service (daemon).

Creating an iSCSI target on FreeBSD, particularly with ZFS, is typically done by exporting a ZFS Volume (ZVOL), which is a block-level device, not a ZFS filesystem/dataset. iSCSI targets present themselves as raw block devices to the initiator (client), w…

In this blog post, I will install and configure FreeBSD/Bhyve to set up a FreeBSD virtualization host.

In this blog post, we will focus on ZFS from a manageability perspective.

In my homelab I have Dell PowerEdge R620 Server with FreeBSD 14.3 and ZFS 2.2.7.

LACP stands for Link Aggregation Control Protocol.

LLDP stands for Link Layer Discovery Protocol.

While testing Wi-Fi quality and network throughput on FreeBSD 14.3 drivers, I realized that before running any benchmarks, it’s important to document my home LAN topology and the network capacity across its zones.

FreeBSD 14.3 should have significantly improved support of WiFi adapters.

Vodafone is one of the internet providers I use in my home lab setup here in Czechia.

While writing my blog post series about IPv6, I realized it would be useful to document publicly available DNS servers.
