I've been playing with computers since I read an Elementary Electronics magazine way back in the 1970s. I started contributing to open source projects in 1998. After that, I gradually moved from being a software developer to being a systems administrator.

Migrating ZFS filesystems from one zpool to another – same host

Leave a Comment / FreeBSD, Open Source, ZFS / By /

Not so long ago, a disk space issue arose. I obtained some new drives (thank you to those who donated) and I consolidated some of the space. However, I had not yet taken care of the problem. For my first example, I’ll copy my vm data over. In my next post, I’ll copy dev.freshports.org to a new dataset. In this post: FreeBSD 15.0 What happened? Yesterday, the chickens came home to roost.

My solution for copying backups around the homelab

Leave a Comment / PostgreSQL, ssh / By /

I have database servers outside the homelab, as in not in my basement. They are in datacenters. I don’t let them push the backups into the basement. Instead, I let them call home asking for the backups to be picked up. I prefer it that way. As I describe it, it may seem complex to do multiple steps when one step will do. However, this solution promises that the backups are ready and

Creating a FreeBSD virtual machine using bhyve-vm

Leave a Comment / bhyve, FreeBSD, Open Source / By /

I had a need for FreeBSD-16.0-CURRENT. I’m already using sysutils/vm-bhyve (Management system for bhyve virtual machines, relevant blog post). These steps really are very short notes.

Hacking openvpn to use syslog with something other than facility = daemon

Leave a Comment / FreeBSD, Open Source, OpenVPN / By /

I don’t see a way to specify the syslog facility for OpenVPN – perhaps I can change that in the code. It would allow logging openvpn to a specific file and being able to rotate that log file. –log-append does not allow for log rotation. In this post: FreeBSD 15.0 OpenVPN 2.6.19 Signals sent to OpenVPN do not affect logging. Thus, I must rely upon syslog and newsyslog to achieve log rotation. At

Script to generate that maintenance.html file for taking my websites into maintenance mode

Leave a Comment / FreeBSD, General, nginx, Open Source / By /

In a recent blog post, I showed you how I was taking my websites into maintenance mode. Shortly afterwards, I wrote about how using $server_name can have odd consequences. Today, I’m writing about the script I just created which will create those maintenance.html files. In this post: FreeBSD 15.0 nginx 1.28.2 bourne shell The script This is the script: [12:17 r720-02-proxy01 dvl /usr/local/www/offline] % cat ~/bin/offline #!/bin/sh # Usage: ~/bin/offline foo.bar "$(date -R

Using variable names in nginx declarations has a price: e.g. ssl_certificate /usr/local/etc/ssl/${server_name}.fullchain.cer;

Leave a Comment / FreeBSD, nginx, Open Source / By /

I recently implemented a fun (to me) and easy solution for taking my web proxy websites offline, either one-by-one, or all-at-once. Today’s post talks about some of the repercussions which followed one-new-thing I tried. In this post: FreeBSD 15.0 nginx 1.28.2 I jump between testing the test host and stage host; both had similar issues. The relevant changes This is the type of change I started to do. Instead of putting the hostname

ddclient 4 changes

Leave a Comment / DHCP, FreeBSD, Open Source / By /

After a 4-hour power outage today (crews were working on the power lines), my home IP address changed, perhaps for the first time in over a year. I also noticed ddclient was no longer installed on my host. This blog post outlines changes from the original article. In this post: I’m mostly documenting my local changes based on the previous post. FreeBSD 15.0 ddclient-4.0.0 Updates to the Ansible playbook for ddclient: https://github.com/dlangille/ddclient/ forked
