On Friday, the latest addition to the #homelab turned up. An Eaton EMA114-10 PDU. A PDU is a Power Distribution Unit. Think of it as a step up from a power strip. This is a 24 outlet, single phase, managed PDU. With it, individual outlets can be monitored for power usage and they can be switched on or off. Access methods include ssh, telnet, serial port, http, and https. This PDU is zero-U, […]

I recently acquired an Eaton EMA114-10 PDU. When adding it to LibreNMS, I did not know what Authorization Algorithm or Crypto Algorithm to use when configuring it for SNMPv3. Searching did not find anything. IRC did. dagb on the LibreNMS IRC channel knew what was used for older EATON devices. Turns out, that hasn’t changed. These are the answers: Auth Algorithm – MD5 Crypto Algorithm – AES I hope this saves you time.

This is not a significant post. It is for the record. I received 20 new LTO4 tapes recently.

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. What I absolutely do not want to happen, and it’s happened recently, is for those packages to be installed on the development environments. Why? It installs to the same location as the working copy of

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

In the interests of maintaining Michael W Lucas in the lifestyle to which he has become accustomed, I am creating this blog post. Although Mr Lucas was the first to post, he is not solely to blame for my burdensome workload. Jan-Piet Mens and Evan Hunt also have much to answer for. Their misdeeds include mentioning newer BIND tools which necessitated an update to an older blog post. The worst of them all,

You might recall that suspect drive from the zpool replace on the weekend. Thomas Hurst suggested: Might be worth overwriting the drive, try to encourage it to actually reallocate the sectors now the data on them is no longer needed. I, being one to take advice from people on the internet, and Michael W Lucas, decided to try his suggestion. The drive in question.
