Outside Temperature From an API in a Shell Script

Wed, 03 May 2023 00:00:00 +0000

I’m interested in collecting some internal temperature data from my servers to look at the effect of adding an NMVe drive. Last week we had a couple of warm days immediately followed by a couple of cool ones. I imagine a 20° ambient temperature change could effect the server temperatures, so I thought it would be good to add that to my temperature logs.

I don’t have a weather station or other automated system for collecting the temperature, but there are several commercial sources for this data which, while probably not as good as a sensor in the server room, will be fine for our purposes.

Mounting NFS shares into LXC containers

Fri, 21 Apr 2023 00:00:00 +0000

I’m playing with Syncthing with the idea that it might be a good replacement for Dropbox. There wasn’t a Docker container listed in the install options, so I thought this might be a good app to run in an LXC.

I’m going to use a share from the NAS, and I’m assuming I’ll need it mount it into the container for Syncthing to access. I’m experienced enough to know that I’m going to want a privileged container, and I thought I’d done all the NFS sharing correctly, but when I tried to mount the NFS share, I was getting an error.

Running Multiple Linux Commands in One Line

Wed, 19 Apr 2023 00:00:00 +0000

Since I’m constantly standing up Linux virtual machines and containers - almost always of the apt variety, I’m constantly typing in:

apt update
apt upgrade

Then hitting enter again to allow whatever installation is needed to proceed. I’ve noticed in some of the commands I’ve been pasting in from installation instructions or StackExchange solutions have been separated by characters that look like it allows several commands to be run one after the other. To cut a long story short, the commands above could be entered like this with double ampersands:

Recursive list of files in Linux

Wed, 08 Mar 2023 00:00:00 +0000

I’ve spent a few hours over the weekend migrating a media library from an external USB drive to the NAS, and in the process reorganised it, and in many cases bulk changed file names. I’ve also added a heap of metadata.

I’d like to check that I haven’t missed any files, but a side by side listing of each data source won’t do the trick, so I’ll probably end up pulling the data into a spreadsheet, but I’d like to get as close as possible with Linux-fu first.
