This morning, I saw this in my logs: In this post: FreeBSD 14.1 r730-03 Looking in he logs, there wasn’t much useful: Searching online, I found swap_pager: cannot allocate bio so I decided to limit ARC size. I’ve done this before, and recently too.. Here is what I added to /boot/loader.conf: I just picked the […]

This post is mostly for myself. I’m just putting my Sunday morning thoughts down for later review and consideration. When Selecting replacements batteries for my Eaton 5PX UPS (5PX2200RT & 5PXEBM48RT), I began to think about: when the power goes off, why can’t I keep using my laptop? Usually, I still have an Internet connection:

Both nut and Nagios are telling me: replace my batteries. Fair enough. The UPS (5PX2200RT) and the external battery pack (5PXEBM48RT) were installed and configured with nut four years and two months ago. It’s time. Usually, I buy compatible third party batteries. Looking at video and images, I’m seeing these units use batteries in a

Sometimes you want to go back to a known good state. And you want to do it quickly, without waiting around. In my case, that’s going to be a zfs snapshot. Today I am preparing to test some code changes so that FreshPorts properly creates a new category. See these recent blog posts for details:
Let’s talk about zfs hold. Based on man zfs-hold: “If a hold exists on a snapshot, attempts to destroy that snapshot by using the zfs destroy command return EBUSY.” Let’s apply that to some FreshPorts snapshots which I don’t want going away: This is your typical FreshPorts website: [15:03 dvl-nginx01 dvl ~] % zfs list

see https://lists.freebsd.org/archives/freebsd-questions/2024-October/005877.html for the full archive. A while back, I changed my FreeBSD jails from using postfix to using dma. I like postfix, but I don’t want to maintain the app in so many locations. dma is less work. I wrote a short blog post about configuring dma and also blogged about replacing postfix with

The time has come for me to consider another application for my TOTP data (think 6-digit codes produced by Google Authenticator or an RSA device. I’ve been using an app called 2STP – I have long liked it. Support for it ended about 7 years ago, yet it continued to slug along on my phone

The type of abuse recently seen on FreshPorts isn’t a big deal. I would ignore it if it was on my own server. However, I’m using a “paid” service and the credits go faster when pillocks do pillocky stuff. While I hope I’ve covered what I’ve done, I’ve been sick with a cold for a
