I like boot environments (BE) on FreeBSD. They were especially handy when building the AWS host for FreshPorts, since I had no serial console. I would create a BE saving the current status, then make some changes. I’d mark the current BE as boot once, so I could boot back in the known good BE. […]

snmpd can be royal pain to configure. I got my hints from Ryan Steinmetz, the maintainer for the FreeBSD port. Lately, net-snmpd has changed how net-snmp-config works. In this post: FreeBSD 12.2 net-snmp-5.9_3,1 Compare my hints with the following, run today with net-snmp-5.9_3,1: [dan@nginx01:~] $ sudo net-snmp-config –create-snmpv3-user -ro -x AES -a SHA -A ‘secret123’

I recently discovered that you can delete all snapshot from a ZFS filesystem with a single command. It came to me via fortune: You can delete a range of ZFS snapshots (a-z) in multiple ways. The following will delete d and all earlier snapshots: zfs destroy mypool/data@%d To delete d and all later snapshots: zfs

I updated net/mosquitto from 1.6.7_1 to 2.0.8 on March 14, 2021. It did not get restarted at that time. It wasn’t until sysutils/anvil brought in a new certificate and attempted to restart mosquitto did the monitoring start detecting the problem: mosquitto wasn’t running. It’s the pid file Looking into it, nothing was logged when starting

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

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.

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

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,

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
