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 […]
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. In this post: FreeBSD 12.1 pam_google_authenticator-1.08 Most of the 2FA I use is time-based one-off passwords (TOTP), as opposed to text messages. These are often 6-digit […]
I backup my databases daily. They get dumped to a disk file and copied somewhere else. Then they are backed up into a file system. Once a month they get copied to tape. Yesterday I upgraded a PostgreSQL database server, and it went well. Overnight, a backup failed. This is the story of how that […]
Be warned, this failed. I’m stalled and I have not completed this. I’m going to do jails within a jail. I already do that with poudriere in a jail but here I want to test an older version of iocage before upgrading my current jail hosts to a newer version. In this post: FreeBSD 12.1 […]
You’ve seen it. A package gets installed. Some shell scripts are included. They get modified. It happens. But how do you know what has changed? I know there is a tool in pkg for this. I know there is a periodic script which uses it. Let’s go looking. In this post: FreeBSD 12.1 periodic $ […]
FreshPorts runs on a FreeBSD server which hosts multiple jails. Two of these jails run PostgreSQL server. When upgrading from one version of PostgreSQL to another, we run pg_dump in the new jail, and load the backup into that database server. I’m writing this blog post to keep track of this procedure so I do […]
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 […]
This is a small desktop / short tower case which is connected to a couple of tape libraries. This post replaces a previous post.
