I am moving my existing IMAP services to a third-party, specifically FastMail. I started this process back in March 2017 when I signed up with FastMail. I did a mail migration then, but never proceeded. At present I am hosting my own IMAP server, via Dovecot, RoundCube, and Postfix, running in a FreeBSD jail. I […]

I am about to make changes to my mail servers. I am changing third-party providers. In anticipation of this change, I will drop the TTL on my DNS MX records. This should minimize the time it takes for this change to take effect. I say should because not all servers honor the specified TTL. I […]

I have been using ezjail since at least 2008 (see earlier blog post). A few years ago, I started deploying iocage on new servers. About three months ago, I starting converting systems from ezjail to iocage. When I converted my first system, I found that the existing documentation for conversion was incomplete. Specifically, symlinks were […]

using syncthing between my OSX laptop and my FreeBSD server

We know the routine. You have a desktop, and a laptop, or perhaps two laptops. You want your files in both places. A shared, remotely mounted directory is not ideal. Instead, let’s have the systems synchronize themselves. That’s where syncthing comes in: Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. […]

I started playing with /usr/local/etc/periodic/security/405.pkg-base-audit as part of a monitoring system. It works fine from the command line, but when I use Nagios plugins, I am getting unexpected results. By unexpected, I mean messages about FreeBSD 10.2. The host in question runs FreeBSD 12.0. The problem cannot be reproduced on the host, only from the […]

I recently became aware that ACME DNS validation can be accomplished via proxy. By proxy, I mean you can update the DNS records of another domain, not the domain for which the certificate is being issued. Why would you do this (as taken from acme.sh DNS Alias Mode): Your DNS provider does not provide API […]

Tomorrow I’ll be doing some server and rack work. I’ll be moving one system into a new chassis, combining two desktops into the old chassis, and putting both chassis back into the rack. There are a bunch of steps here and I want to write them down so they all get done. These steps were […]
