Creating a wireguard connection between my home and colo – failed attempt

NOTE: I wrote this, got stuck, then went a slightly different direction: I stopped using wg set Instead, I updated the configuration files directly I was not satisfied with the wg approach Although it is great for modifying things on the file, I don’t think it helps novices learn Wireguard I’m leaving it here anyway. …

Here I am, sitting on a beach, writing a blog post, and sipping a cool adult beverage. Reading email. I see this: I quickly ssh into the host to check zpool status: Lines 15-17 are relevant. There was a resilver event, which completed at 08:49:48 The vdev state changed event occurred at 08:49:34 That all …

When updating to FreeBSD 13.1, I started getting these messages from sysutils/logcheck: egrep: trailing backslash (\) This post will document how I tracked down the problem.

I forgot to enable compression on ZFS

I forgot to enable compression on this FreshPorts node. I have no idea why/how. After doing this, I went to a directory with a lot of space and copied stuff around. [aws-1 dan /jails/ingress01/var/db/freshports/message-queues/archive] % sudo mv 2021_03.tar.gz 2021_03.tar.gz.tmp 21:01:28 [aws-1 dan /jails/ingress01/var/db/freshports/message-queues/archive] % sudo mv 2021_03.tar.gz.tmp 2021_03.tar.gz 21:01:38 That will free up *some* space. …

Monitoring FreeBSD jails from the host

It was May 2021 when I tweeted about monitoring FreeBSD jails which had jail IP addresses only in the 127.0.0.0/8 range. Yesterday, nearly 6 months later, I did the first test of this. This came up because I’m getting a new FreshPorts node ready. I’ve created a file in the jail to be run from …
