Another pair of SATADOM devices

Now that r730-01 is booting from SATADOM devices (which are directly attached to the M/B, thereby freeing up drives bays / PCIe slots for larger devices), I thought it wise to buy a second pair. For two reasons: The price of used devices was pretty good It’s good to have spares nearby In this post: FreeBSD 14.3 smartmontools-7.5 smartctl info Here is the SMART info. Next drive: My notes The power on hours […]

PostgreSQL: MD5 password support is deprecated – updating the user passwords

Eight years ago, PostgreSQL introduced scram-sha-256 hashes for passwords. Eleven months ago, MD5 was deprecated. Yesterday, I got caught up with all this. Some of this post will deal with how I fixed it, but mostly it is documenting (for myself) what I did. The fix covers several services and takes place over multiple days. First, some background on why this change has come into focus for me. I have a FreeBSD jail

Experimenting with compression=zstd

Following on from my previous post where I tested lz4, let’s try compression=zstd.

RIPE Atlas – Total Availability : 100.00%

Yes, this is blatant bragging. But realistically, this is more a function of my ISP (Verizon FiOS) and my electricity supplier (PECO) than my abilities. To be fair, it is more contingent upon no power failures than anything else. I do have a UPS, but that’s only good for about 10-20 minutes. For August 2021, my home network had 100% uptime, according to RIPE. I’ve been hosting this device since 2013-05-29 (just over

The odd battery post

I have some odd batteries in use at home. This post will enable me to look them up without opening up the device. Wireless light switch This is used in the server room (aka laundry room in the basement) Cable tester I have had this cable tester for many years. It’s an Ideal LinkMaster. It’s always done well by me. This what the cable tester looks like from the outside.

link request spammers – sometimes they help

If you have a blog, or anything online, I’m sure you have received an email saying: Hey, great article, would you mind linking to my website please? A few days later: hey! did you get my email? Then later still: I know you’re busy…. The one I received today was at first annoying but then turned out helpful. I went to that blog post but I couldn’t find a link to Wikipedia anywhere.

Right up until you need it, resilience looks like waste

This sounds slightly political, and it is. Intentionally so. 1. the capacity to recover quickly from difficulties; toughness. “the often remarkable resilience of so many British institutions” 2. the ability of a substance or object to spring back into shape; elasticity. “nylon is excellent in wearability and resilience” Christophe Pettus recently said: Right up until you need it, resilience looks like waste If you use ZFS, you should know about this issue. For

Archives are important to retain and pass on knowledge

Archives are important. When they are public and available for searching, it retains and passes on knowledge. It saves vast amounts of time. Case in point I started the copy-backups-to-tape process today. This appeared on the tape server: Jan 7 19:12:08 r720-01 kernel: (sa0:mps0:0:5:0): 64512-byte tape record bigger than supplied buffer Damn. Do I have a tape problem? Search results When searching for this, I found this FreeBSD Forums post from 2016 where

Registering FireTV – unable to receive verification code on phone

I was setting up my FireTV (seems to be a TV with built-in FireStick functions). I was stuck, waiting for a verification code which never arrived on my phone. I was expecting an incoming text. I was wrong to expect that. I had gotten to the stage of logging in with my Amazon credentials and was getting told (and I paraphrase here): Because of the way your account is set up, your login

Why is my network offline? An investigation

Happy New Year. This morning I received an email at 4:50 AM local time telling me that my camera system had been offline for 10 minutes. Based on that, I tried to access my internal monitoring system from outside. Nothing. Later emails indicated other external systems had issues connecting to the internal network. As I type this, I just arrived at home, I’m sitting on the couch and I’ve not touched the network
