When administering a Confluence Cloud instance, we encountered the issue where I needed to use the API to check every space’s permissions. However, in Confluence’s REST API, you need to have “Read” permissions on a space to be able to read the permissions. To get this access, you can (as an admin) go to the […]
I wrote a tool recently that allows taking log files from the Cisco-managed S3 bucket, and outputs each log line as a Syslog message, with the content of the log line as a JSON-formatted message. Details of the Cisco-managed S3 bucket are here: https://docs.umbrella.com/deployment-umbrella/docs/cisco-managed-s3-bucket Once logged onto disk, the output of this tool looks like: […]
To backup my server I uses a tool called restic (https://restic.net/) – It’s great. I’ve recently been testing out using MEGA (https://mega.io/) as the backend storage for my backups, and to integrate that with restic, you use rclone (https://rclone.org/) as a storage driver. Sounds complicated, but it’s really not:restic –talks-to–> rclone –talks-to–> mega However, during […]
I run nextcloud on my home server. The primary purpose is for file sync, which I also use to back up my photos from my Android phone, and also I use the Notes app synchronised with my phone. Here’s a bottom-up description of the server setup. The Server Hardware The server is an old desktop […]
These are some tips I’ve put together on how to create a certificate using acme.sh then import it into a FortiGate firewall for use on the SSL-VPN or similar. Getting the Certificate and Key file I won’t go into too much detail on this – just use the acme.sh documentation to get a key+certificate: https://acme.sh […]
We use phpIPAM to manage all our IP Addresses, and we have recently built integrations between phpIPAM and our Kea DHCP server for reservations, and also into our BIND DNS server. These have been running on a schedule, which has worked well, but doing it that way means that it can take a while after […]

Learn Your Tools
Just read a post by Drew DeVault: https://drewdevault.com/2020/11/06/Utility-vs-usability.html I very much agree. So many people treat working with computers as “I don’t like it but I have to do it.” Often these people learn only the minimum required to get something done. I think that, as professionals, we need to treat computers as tools to […]
I’ve been moving a bunch of my shell scripts to python recently, because of how much better it handles the concept of “a process didn’t run successfully”. Consider the bash script: What happens here if Command 2 fails? Note that we still get the success message at the end – bash silently ignored our error-ing […]
I’ve started a new project! I recently talked about my experiments with coconut-lang here: https://jaytuckey.name/2020/10/25/thoughts-on-coconut-the-compile-to-python-functional-language-extension/ I’ve now started a project using coconut! It’s what I’m calling a “Dead Man’s Switch” (DMS) monitoring tool. The idea is this: Every cron job / scheduled task sends an update to the DMS monitor The monitor records the updates […]
