This is just a placeholder for me to find this later. I was cleaning up some old snapshots. I’m not sure I should have removed those snapshots and I’m saving this here for next time I use bectl. [dan@slocum:~] $ grep -v autosnap ~/tmp/snapshots/snapshots zroot/bootenv/default@2020-01-11-18:16:51 zroot/bootenv/default/tmp@2020-01-11-18:16:51 zroot/bootenv/default/usr@2020-01-11-18:16:51 zroot/bootenv/default/usr/local@2020-01-11-18:16:51 zroot/bootenv/default/usr/obj@2020-01-11-18:16:51 zroot/bootenv/default/usr/src@2020-01-11-18:16:51 zroot/bootenv/default/var@2020-01-11-18:16:51 zroot/bootenv/default/var/audit@2020-01-11-18:16:51 zroot/bootenv/default/var/empty@2020-01-11-18:16:51 zroot/bootenv/default/var/log@2020-01-11-18:16:51 zroot/bootenv/default/var/tmp@2020-01-11-18:16:51 […]

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 […]

Spare fiber cards

Sometimes I’ll be thinking about the hardware I have which is not in use. I’ll know it exists, but not the details. I’ll be in the wrong part of the house to have a quick look, or I might be nowhere near the house when the topic comes up. This post fixes that. These are […]

2FA has its critics: It’s so unreliable! Phones are so easily hijacked It’s not a lot of added security etc Some of these make assumptions not necessarily in evidence.

Today I found this annoying situation on FreeBSD 12.1 in a FreeBSD 12.0 jail (neither of which are directly relevant to the problem at hand). [dan@serpico:~] $ sudo pkg audit -F vulnxml file up-to-date pkg: vulnxml parsing error: no element found pkg: cannot process vulnxml After a bit if thinking, I figured the vulnxml file […]

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 […]
