I use irssi and a script keepnick for grabbing my nick when it becomes available. From time to time, I get this message: Irssi: Unknown command: keepnick How do I fix this? It has happened before. I did not blog it. Ouch. I could have this solved by now if I had. My solution, this time: sudo pkg delete irssi-scripts I also created this file: [dan@supernews:~/.irssi] $ cat startup load perl keepnick dvl […]

Tonight I got blocked by iocage and handling a ZFS filesystem from within an iocage jail. These are the steps I followed to convert that jail from iocage to a vanilla jail. The variable To make this solution easier to use, at least for me, on future jail migrations, I have these variables: For example, my devgit-nginx01 jail is at: [dan@knew:~] $ zfs list system/iocage/jails/mysql56 NAME USED AVAIL REFER MOUNTPOINT system/iocage/jails/mysql56 11.5G 20.6T

I have a few development jails dedicated to my work on FreshPorts. It’s been a hobby of mine since the late 1990s. The code I create gets packaged, ready to deploy onto the test, stage, and production hosts. EDIT 2025-12-23 Since writing this post pkg-2.5.0 has a feature for this very goal. See this reddit post. In short: pkg install -U –register-only FreeBSD-vi FreeBSD-vi-dbg I haven’t used it. What I absolutely do not

Today I faced the first implications of deciding to tightly restrict the use of nsupdate keys for modifying TXT records for dns-01 challenges with Let’s Encrypt. Context This section should be on news.freshports.org and you can skip it to get to the real stuff. Today I’m working on a mostly automated FreshPorts node deployment. A FreshPorts node consists of: host server – A FreeBSD host which contains the other nodes database – holds

Yesterday, I started a zpool replace. It finished overnight, and dropped the suspect drive out of the vdev. The resilver finished in the middle of the night: As you can see, da22p1 has taken the place of da17p1. The resilver took As the new drive is being resilvered, I started looking at metrics. Here is gstat. Look at how da22, the replacement drive is getting all the writes, compared to the others. LibreNMS

In this post I will replace a working, but suspect, drive with another drive. No down time. The server is knew.

It is time to replace /dev/da17 in knew. The replacement drive is also documented. The replacement procedure has also been documented. An upcoming blog post will document the replacement.

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 would redirect incoming ports 80 and 443 to my webserver, and Nginx/Apache would take care of the rest.

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.

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 be imported using its name or numeric identifier. config: data01 ONLINE mirror-0 ONLINE gpt/S59VNS0N809087J_S00 ONLINE gpt/S59VNJ0N631973D_S01 ONLINE mirror-1
