I have two new drives for zuul. I’ll start adding them into the zpool soon. For now, here is the smarctl output for the new drives. I’ll start some tests on them soon. By new, I mean new to this host. The drives have 17,000 hours on them. [dan@zuul:~] $ sudo smartctl -a /dev/ada2 smartctl […]

Today is the day after BSDCan 2019. The power cables and extension cords from the hacking lounge have been laid to rest in an Ottawa basement until next year. Sitting in my parents garden, I noticed some Nagios cert warnings: I logged into my certificates server (the website from which all my hosts download their […]

ZFS is very flexible about mountpoints, and there are many features available to provide great flexibility.

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. […]
