System Administration

FreeBSD is my preferred OS thanks to ZFS, disk encryption, the wholly-owned base system, ports/packages, jails for securing network services, and the community.

A few years ago, I found myself looking for a new OS for day-to-day use. I'd been using Mac OS X for several years because my employer provided a MacBook Pro and I really loved the nice, clean Aqua UI on top of a POSIX compliant core. However, I was setting up a desktop, didn't want to spend a fortune on Apple hardware, and wasn't sure I liked the direction Apple was heading with OS X by making it more like iOS. My requirements pretty much boiled down to security (including support for full-disk encryption), stability, flexibility, software freedom, and a thriving community for those inevitable times when I would need some wisdom. If you're reading this blog, I probably don't need to tell you why Windows was ruled out before the competition started.

As a 'power user' who wanted to replace my laptop with something inexpensive and low maintenance, I gave a Chromebook an honest try. Was it up to the challenge?

This is the first post in a 3-part series on using a Chromebook as a power user. It gives a high-level overview of how I'm using my Chromebook and some basic Chrome OS configuration steps. Part 2 digs deeper to show advanced users how to use crouton to install Debian Linux in a chroot. Part 3 finishes up by configuring LXDE and connecting to a remote FreeBSD desktop running xrdp.

The RDP apps on Chrome OS left me wondering if my Chromebook would be useless. Then I found crouton and installed Debian Linux in a chroot to expand my options.

This is the 2nd post in a 3-part series on using a Chromebook as a power user. Part 1 gave a high-level overview of how I'm using my Chromebook and some basic Chrome OS configuration steps.

FreeBSD's root user can easily search its shell command history using the arrow keys. Add the same search capability in the Bash shell with this change.

By default, the FreeBSD root user can type part of a command and then search through history for previous commands beginning with those characters using the up/down arrow keys. If you're new to FreeBSD or csh, you might think the convenient shell history search is specific to root or csh/tcsh. Fortunately, it's not. You can get similar functionality in Bash by creating or editing ~/.inputrc to add the following lines:

After installing Debian Linux in a chroot on my Chromebook, I slimmed LXDE down a bit before connecting to my FreeBSD desktop running xrdp.

FreeBSD 10.2 and higher use mismatched repos for packages and ports. This shell script simplifies updating your ports tree from the current quarterly branch.

Note: This post and script were originally written for the SVN ports repo, but both have been updated since ports were migrated to Git.

I use some shell script libraries to make FreeBSD system configuration easier. They're now available as freebsd-scripts on GitHub for anyone to use and improve.

I recently switched my hosting provider from Digital Ocean to Vultr to get tighter control over the configuration—a more "pure" FreeBSD installation. While updating my notes to prep for the install, I considered how many configuration steps were basic file editing: add this line under that line, uncomment this line, comment that line, etc. I love the simplicity that comes when the code is the documentation, so I decided to create a small file I/O library to make it easier to write shell scripts for system configuration. Why bother maintaining notes to describe manual changes when I could write a script to perform the changes automatically?

Deploying a Helm chart to Kubernetes just to query resources is time consuming. It's possible to directly query a Helm chart using JSON with this simple trick.

Happy querying!

Multiple NPM packages were hit by supply chain attacks recently: ua-parser-js, coa, rc. How can you check your installed NPM packages for an affected version?

jq can be used to query NPM package data
