Tailscale Feature Highlight: SSH, Serve, and Funnel

I've spent the past two years in love with Tailscale, which builds on the secure and high-performance Wireguard VPN protocol and makes it really easy to configure and manage. Being able to easily (and securely) access remote devices as if they were on the same LAN is pretty awesome to begin with, but Tailscale is packed with an ever-expanding set of features that can really help to streamline your operations too.

I Ditched vSphere for Proxmox VE

Way back in 2021, I documented how I had built a VMWare-focused home lab on an Intel NUC 9 host. The setup was fairly complicated specifically so I could build and test content for what was then known as vRealize Automation. My priorities have since shifted1, though, and I no longer have need for vRA at my house. vSphere + vCenter carries a hefty amount of overhead, so I thought it might be time to switch my homelab over to something a bit simpler in the form of Proxmox VE.

Using systemctl edit to Delay Service Startup

Following a recent update, I found that the Linux development environment on my Framework Chromebook would fail to load if the Tailscale daemon was already running. It seems that the Tailscale virtual interface may have interfered with how the CrOS Terminal app was expecting to connect to the Linux container. I initially worked around the problem by just disabling the tailscaled service, but having to remember to start it up manually was a pretty heavy cognitive load.

How to Ask For Help

I spend a lot of my time and energy answering technical questions, both professionally and "for fun" as a way to scratch that troubleshooting itch. How a question is asked plays a big factor in how effectively I'll be able to answer it. Years ago I came across Eric Steven Raymond's How To Ask Questions The Smart Way and it really resonated with me. I wish everyone would read it before asking for technical help but I recognize it's a pretty large doc so that's an unrealistic wish.

Cat a File Without Comments

It's super handy when a Linux config file is loaded with comments to tell you precisely how to configure the thing, but all those comments can really get in the way when you're trying to review the current configuration. Next time, instead of scrolling through page after page of lengthy embedded explanations, just use: egrep -v "^\s*(#|$)" $filename # [tl! .cmd] For added usefulness, I alias this command to ccat (which my brain interprets as "commentless cat") in my ~/.

Tailscale on VMware Photon OS

You might remember that I'm a pretty big fan of Tailscale, which makes it easy to connect your various devices together in a secure tailnet, or private network. Tailscale is super simple to set up on most platforms, but you'll need to install it manually if there isn't a prebuilt package for your system. Here's a condensed list of the steps that I took to manually install Tailscale on VMware's Photon OS, though the same (or similar) steps should also work on just about any other systemd-based system.

Using VS Code to explore giant log bundles

I recently ran into a peculiar issue after upgrading my vRealize Automation homelab to the new 8.3 release, and the error message displayed in the UI didn't give me a whole lot of information to work with: I connected to the vRA appliance to try to find the relevant log excerpt, but doing so isn't all that straightforward given the containerized nature of the services. So instead I used the vracli log-bundle command to generate a bundle of all relevant logs, and I then transferred the resulting (2.

Fixing WSL2 connectivity when connected to a VPN with wsl-vpnkit

I was pretty excited to get WSL2 and Docker working on my Windows 10 1909 laptop a few weeks ago, but I quickly encountered a problem: WSL2 had no network connectivity when connected to my work VPN. Well, that's not entirely true; Docker worked just fine, but nothing else could talk to anything outside of the WSL environment. I found a few open issues for this problem in the WSL2 Github with suggested workarounds including modifying Windows registry entries, adjusting the metrics assigned to various virtual network interfaces within Windows, and manually setting DNS servers in /etc/resolv.

Abusing Chrome's Custom Search Engines for Fun and Profit

Do you (like me) find yourself frequently searching for information within the same websites over and over? Wouldn't it be great if you could just type your query into your browser's address bar (AKA the Chrome Omnibox) and go straight to the results you need? Well you totally can - and probably already are for certain sites which have inserted themselves as search engines. The basics Point your browser to chrome://settings/searchEngines to see which sites are registered as Custom Search Engines: Each of these search engine entries has three parts: a name ("Search engine"), a Keyword, and a Query URL.

Docker on Windows 10 with WSL2

Microsoft's Windows Subsystem for Linux (WSL) 2 was recently updated to bring support for less-bleeding-edge Windows 10 versions (like 1903 and 1909). WSL2 is a big improvement over the first iteration (particularly with better Docker support) so I was really looking forward to getting WSL2 loaded up on my work laptop. Here's how. WSL2 Step Zero: Prereqs You'll need Windows 10 1903 build 18362 or newer (on x64). You can check by running ver from a Command Prompt:
