A Week With Plan 9

I spent the first week of 2021 learning an OS called Plan 9 from Bell Labs. This is a fringe Operating System, long abandoned by it’s original authors. It's also responsible for a great deal of inspiration elsewhere. If you’ve used the Go language, /proc, UTF-8 or Docker, you’ve used Plan 9-designed features. This issue dives into Operating System internals and some moderately hard computer science topics. If that sort of thing isn’t your bag you might want to skip ahead. Normal service will resume shortly.

Exploring Swap on FreeBSD

On modern Unix-like systems such as FreeBSD, “swapping” refers to the activity of paging out the contents of memory to a disk and then paging it back in on demand. The page-out activity occurs in response to a lack of free memory in the system: the kernel tries to identify pages of memory that probably will not be accessed in the near future, and copies their contents to a disk for safekeeping until they are needed again. When an application attempts to access memory that has been swapped out, it blocks while the kernel fetches that saved memory from the swap disk, and then resumes execution as if nothing had happened.

How to set up FreeBSD 12 VNET jail with ZFS

How do I install, set up and configure a FreeBSD 12 jail with VNET on ZFS? How can I create FreeBSD 12 VNET jail with /etc/jail.conf to run OpenVPN, Apache, Wireguard and other Internet-facing services securely on my BSD box?
FreeBSD jail is nothing but operating system-level virtualization that allows partitioning a FreeBSD based Unix server. Such systems have their root user and access rights. Jails can use network subsystem virtualization infrastructure or share an existing network. FreeBSD jails are a powerful way to increase security. Usually, you create jail per services such as an Nginx/Apache webserver with PHP/Perl/Python app, WireGuard/OpeNVPN server, MariaDB/PgSQL server, and more. This page shows how to configure a FreeBSD Jail with vnet and ZFZ on FreeBSD 12.x.

Creating Comfy FreeBSD Jails Using Standard Tools

Docker has stormed into software development in recent years. While the concepts behind it are powerful and useful, similar tools have been used in systems for decades. FreeBSD’s jails in one of those tools which build upon even older chroot(2) To put it shortly, with these tools, you can make a safe environment separated from the rest of the system.

Routing and Firewalling VLANS with FreeBSD

In this article we are going to look at and integrate two network isolation technologies, VLANs and VNET. VLANs are common place, and if you have done some network management or design then you are likely to have interacted with them. The second are FreeBSDs VNET virtual network stacks, a powerful network stack isolation technology that gives FreeBSD jails super powers.
Ethernet VLAN (standardised by IEEE 802.1Q) are an extension to Ethernet and provide an essential method for scaling network deployments. They are used in all environments to enable reuse of common infrastructure by isolating portions of networks from each other. VLANs allow the reuse of common cables, switches and routers to carry completely different networks. It is common to have data that must be separated from different networks carried on common cables until their VLAN tags are finally stripped at a gateway switch or router.
