Virtual hosts for a website are a thing. One webserver can host multiple websites. They can all be on the same IP address, different IP addresses, different ports, etc. This post is about using a proxy service. Before I started with this solution, at home I hosted every website on the same server. My firewall […]

This work was done in August. Since then, I have replaced the APC with an Eaton 5PX, and I am much happier. This might make for interesting reading, but that depends on how bored you are.. Following on from my failed calibration attempts, I thought I would try it again this morning before work. In

I have these boot drives, I want to copy them to another. They both happen to be zroot and bootable. I booted from mfsBSD and imported both new and old zroot, using the pool ID shown by zpool import -N. root@mfsbsd:~ # zpool import -N pool: data01 id: 2668514456528412656 state: ONLINE action: The pool can

Following on from my recent nut setup, this is the second in a series of three posts. The next post will deal with adjusting startup and shutdown times to be sure everything proceeds as required. I want to test the host shutdown mechanism without: unplugging the UPS from the mains powering off the UPS without

It is time to replace my existing UPS with another one. I’m getting only 3 minutes of runtime with the existing batteries (and new batteries, after recalibration). It was suggested I buy an Eaton 5PX. I wasn’t convinced. This is the first of three articles about nut. The second is about testing the shutdown. The

I encountered, and later solved, a DNS issue on a FreeBSD jail. The jail is my web proxy, of sorts. I have one public IP address, which is dynamic (not relevant, but mentioned only in passing) so all incoming web traffic goes to a single internal RFC-1918 IP address. From there, nginx does reverse proxies

Today was battery replacement day at my place. The UPS batteries were replaced without downtime. That doesn’t mean there wasn’t downtime. I am not documenting this in real-time. This is post-event analysis. First, I wanted to change the battery replacement date, so I ran acptest on the pfSense server, to which the UPS is connected

I noticed a problem with a newly-created freshports daemon script: starting it would sometime freeze the terminal session. The rc.d script The rc.d script was fairly straight forward: Nothing odd there, right? This first happened a week or so ago. I moved on it and decided to look into later. But wait, there’s more This
