Everyday I connect to a number of servers, and everyday I send the same command to a list of servers.
Sometimes it is Ubuntu servers, sometimes Debian servers; I needed a way to slice and dice my list of servers, and start a clustered ssh session with the resulting sliced and diced list of servers.
Enter tmux, tmux-cssh, and some custom bash scripting.
A little while ago I posted about Let’s Encrypt as a method of getting SSL Certificates for free.
Recently I had a customer who wants a community website, and they want to offer “communityName.example.com” URLs.
In this post I’ll explain how I use Dehydrated to genetrated wildcard Let’s Encrypt SSL certs.
I’ve been playing around in web development for years, in fact, the first web “application” I wrote was in 1994, the year the world wide web was available to the general public in New Zealand.
The last couple of years I’ve been focused on Progressive Web Apps (PWA’s), and this includes using service workers, which are notoriously bad at breaking the refresh button in browsers.

So here is your TerminalAddict.com gift for 2020 🎁🎁🎁
So, I run a few websites 😉 and most of those websites (including this one) I have Google Analytics installed.
But server logs can provide different information. So I’m going to setup graphing and tracking my server access logs.
I can be described as a network engineer, sometimes, and sometimes a system admin. As such, keeping track of how customers internet is working is reasonably important.
Most customers use Speedtest.net as a way of testing their internet connection, so I figured I would clobber together a script that keeps a bit of history, and make some pretty graphs 😅.
