Overlay networks for fun and retrocomputing (a post preserved from the past)

For several years, a small group of friends and I have been considering building a private overlay network for operation of our more esoteric, old, or weird networking needs. The work once again fell by the wayside as life happens, but once again, the discussion came up. Rather than attempting to brainstorm the ideas up again, I’m writ...

Using Tasmota without a network (a post preserved from the past)

Using Tasmota in a completely offline configuration is extra special challenge. The use case was regularly operated events with no need for specific times. These are notes on how to accomplish that. Time based triggers do not fire until Tasmota thinks it has a valid clock. A valid clock is defined as syncing up to an NTP server, or hav...

Debugging node with mdb (a post preserved from the past)

TL;DR: Being able to see the stack trace and investigate the values in those stack frames from a failed node process makes it much easier to understand the error messages and what has gone wrong. mdb on SmartOS makes this possible, arguably, even easy. I run several small Triton Smart Data Center installations, both for fun and as part...

haproxy, chrome tcp preconnect, and error 408 (a post preserved from the past)

This is my guide to making haproxy work reasonably with the deployment model I’m constructing. In broad strokes, I’m looking to have haproxy running on a host which is acting as an http and https front end for a large number of web servers living on a private network, each hosting an individual web site. But first I had to make haproxy...

Using Joyent's Triton for testing network hardware (a post preserved from the past)

Or, an amusing misuse of a cloud datacenter operating system. As a reminder, I’m using this product in an entirely weird way, and any thing I’ve listed below should not be seen as a shortcoming of the product. I’ve pushed this product to a weird edge, and it’s performing admirably. Problem statement: I need to test a new stack of switc...

Bootstrapping Triton on whatever you can find (a post preserved from the past)

As part of my testing environment at work, I was provided some hardware to run Triton on. This isn’t the Joyent recommended hardware stack, but it meets many of the requirements, so it became a matter of getting it all up and running on this hardware. Other hardware was not a choice. I had some advantages. For instance, all 3 servers w...

The Montana Trip (Part 2)

Traveling during the second week of November is a mixed experience. On one hand, crowds are not a problem, but sometimes places are just closed when I show up on a Tuesday. The South Dakota Air and Space Museum is one such place, located right on the edge of Ellsworth Air Force Base. Thankfully, a lot of the exhibits are parked outside...

The Montana Trip (Part 1)

In November 2021, I scheduled a pick up of my Go Fast Camper in Montana. I took this as an opportunity to go explore some national parks on the way. If you have any reason to drive I-90 in South Dakota, take, do not bypass, the badlands scenic bypass. These photos do not do the place justice. The land is active in the sense that the ba...

Road Trip travel time planning.

Having just got done with a trip to Montana, let me inform you of a planning detail. The map systems will tell you this is a 24 hour drive, and reasonably, you might think that means you can do it in two 12 hour days. You are most likely wrong. The trip planning software all assumes that you will be going the speed limit the entire tim...

From Google On-Hub to Ubiquiti UniFi Dream Machine Pro

Context: I recently migrated my home network from a first generation Asus Google Onhub device to a UniFi Dream Machine. The Onhub has been doing the job of operating my home network since 2016, and on the whole, has done reasonably well. I have, however, hit the limits of what I can do reasonably with it with regards to vlans and multi...
