Traefik with CrowdSec

In the Traefik static configuration (usually traefik.yml), add this to load the CrowdSec plugin: (The name for the plugin is defined here as crowdsec-bouncer-traefik-plugin.) Then, in your dynamic configuration, add this (I’ve used a separate file dynamic_conf/050-plugin-crowdsec-bouncer.yml): (The name for this new middleware defined here is crowdsec-bouncer. It uses the crowdsec-bouncer-traefik-plugin defined in the previous step. Make sure these names match.)… Read More: Traefik with CrowdSec »

Audiobook authoring on macOS

The audiobooks and radio dramas I’ve collected over the years mostly come as a bunch of MP3 files, often accompanied by some JPG with cover art and sometimes a TXT file with a teaser text and some background information like the names of the voice actors. However, nowadays, there’s a much better format: M4B. This… Read More: Audiobook authoring on macOS »

RTL9210 NVMe Enclosure Firmware Update

By now I have 2 of those Ugreen M.2 NVMe USB 3.2 SSD enclosures. One of them is attached to my DELL monitor which is attached to my MacBook Pro M1 for TimeMachine backups and just works™ for almost 4 months now. I’ve recently bought a second one (and also the same SSD as in… Read More: RTL9210 NVMe Enclosure Firmware Update »

Realtek RTL9210 and TRIM

I’ve recently started buying M.2 drives instead of traditional 2.5” SSDs. For USB enclosures I went with a UGREEN M.2 NVMe USB3.2 Gen2 enclosure that comes with all the bells and whistles. They have a Realtek RTL9210 chip which does support the “discard” or TRIM operation to mark unused space on the SSD. However, some… Read More: Realtek RTL9210 and TRIM »

Docker-Compose and automatic mounts

If you want your Docker container to use data from a network share, people tend to mount the share to a directory outside of Docker and then point the Docker volume to that mounted path. However, Docker-Compose also supports mounting volumes and brings some advantages. E.g. for a SMB/CIFS share, the relevant parts in your… Read More: Docker-Compose and automatic mounts »

CrowdSec and Pushover notifications

A while ago, I’ve upgraded from fail2ban to CrowdSec. Similar to fail2ban, it analyses various logfiles to detect malicious acts and actors. But CrowdSec also pulls lists of malicious actors that other users have detected – and blocks them before they even get a chance to try their luck. (Which means it also reports incidents… Read More: CrowdSec and Pushover notifications »

ISDT C4 EVO battery charger firmware downgrade

A while ago, I’ve bought the ISDT C4 EVO USB-C-powered battery charger to replace my MAHA C9000 (of which there seems to be a new “Pro” model available). The ISDT charger gets regular firmware updates which add new features and optimises the charging modes for different battery chemistries.

HP EliteBook 810 Cloud Recovery and GPT

I’ve recently acquired an old HP EliteBook Revolve 810 G3 and wanted to reset that to the factory state. Luckily, this already supports HP’s Cloud Recovery feature where you can download the recovery image from the Internet and write it to a USB drive. There’s even a choice between Windows 7 and Windows 10. However,… Read More: HP EliteBook 810 Cloud Recovery and GPT »

Simple port forwarding using nftables

After adding a new penguin to my zoo and moving around a few services, I had the need to re-route HTTPS traffic to a different host for doing all the SSL handling (which would then send a request back – but via HTTP on a different port). The simplest way to do this is to… Read More: Simple port forwarding using nftables »

Easy file sharing via Docker

To quickly setup an FTP server or SMB share using a Docker container instead of fiddling with the system daemons, I’ve found these: FTP For bringing up an FTP server, I’ve found Gareth Flower’s vsftpd container: Here, it’s important to also map ports 40000 – 40009 for PASV FTP to work. The container automatically creates… Read More: Easy file sharing via Docker »
