Let’s Encrypt V3

Posted on 1 June 2022 by matthannan

The Acme script that I use, like many people out there, to keep my Let’s Encrypt TLS/SSL certificate updated has recently had a breaking change of an upgrade. Namecheap, my hosting provider, is using an older version of OpenSSL.

Posted on 19 January 2022 by matthannan

Electricians are arrived at the house at about 8:00AM. Told me it’d be about four hours to install the 240-volt from the circuit breaker panel to the outdoor heat-pump. They were done a touch past 10:00AM.

Today, they installed the four head-units, the backer plates for the exterior channels, and the pad for the outdoor compressor. Tomorrow they install the line sets and hopefully the outdoor compressor.… Read the rest

Installing Unifi controller Docker container on Synology NAS – Thiago Crepaldi

Posted on 17 July 2021 by matthannan

Really, I used this just as a guide to update the Unifi controller in the Docker container. You could do that a time or two before it gets simple, which it is. Just a new way of doing things, I guess.… Read the rest

TP-Link is no Cisco: VLAN configuration

Posted on 4 July 2021 by matthannan

On the surface, my TP-Link T2600G-28TS v3 managed switch appears to have everything that I would expect to have for some intermediate networking in the home. Most of my complaints with the device, to date, have been minor, such as the idle time-out having a max of 120 seconds.… Read the rest

Beginning of the End? NTP Server Migration

Posted on 3 May 2021 by matthannan

A few weeks back, we had an unexpected power-outage at the house. As the Raspberry Pi does not natively have a real-time clock built into it, this plays havoc on the network. Somehow, NTP and DNS are linked in this space.… Read the rest

The Tale of the Two NAS Boxes

Posted on 2 April 2021 by matthannan

Wow, what a run this was! I got tired of waiting for the WD MyBook or whatever it was called to be back in stock, so I started looking for better solutions. OpenMediaVault was not really getting things done for me.… Read the rest
