Remote headless OpenBSD installation
- A lot of server providers only offer a limited number of operating systems to be easily installed on their boxes
- Sometimes you'll get lucky and they'll offer FreeBSD, but it's much harder to find ones that natively support other BSDs
- This article shows how you can use a Linux-based rescue system, a RAM disk and QEMU to install OpenBSD on the bare metal of a server, headlessly and remotely
- It required a few specific steps you'll want to take note of, but is extremely useful for those pesky hosting providers ***
Building a firewall appliance with pfSense
- In this article, we learn how to easily set up a gateway and wireless access point with pfSense on a Netgate ALIX2C3 APU
- After the author's modem died, he decided to look into a more do-it-yourself option with pf and a tiny router board
- The hardware he used has gigabit ports and a BSD-compatible wireless card, as well as enough CPU power for a modest workload and a few services (OpenVPN, etc.)
- There's a lot of great pictures of the hardware and detailed screenshots, definitely worth a look ***
