A few years ago I migrated my Teamspeak3 installation to Docker. Until now this ran like a charm with minimal management effort. For some reason the configured admin password, which is displayed once on the initial startup of Teamspeak3, did not work for me anymore.

The backup has to be done locally inside the LAN and encryption at rest is a must-have. tl;dr: Resilio Sync hosted on a Raspberry Pi / Odroid / NUC does the job perfectly with their app. Nextcloud is far slower and the FolderSync … [Read more…]
Issue: I need to get a notification if a necessary volume on my Linux device is not mounted, as this volume cannot get automatically mounted because a passphrase is required. The curl-request is dependent on the custom DNS (Pi-hole). When setting up my Intel NUC I decided that all my persistent data of the running … [Read more…]
