Wireguard Server/Client
We use Wireguard VPN client on hangdevice because it allows us to have a secure privat IPv4 (and possibly IPv6) tunnel to a known server. This also works in case the public IPv6 system of Freifunk fails (which was tested a lot). That means that Wireguard is th...
Duet 2 and Duet Web Control
Network configuration The Duet controller is attached to Raspberry Pi by USB and by LAN to router. This gives great flexibility. The LAN settings can be done like described in Duet 2 Ethernet Web Control (DWC). Sample configuration for LAN ;Networking Stuff...

Webcam streaming with mjpg-streamer
The webcam used at Trikarus is used to deal for monitoring purposes and timelapse videos. Public embedding of the screen would create much traffic so we keep it for internal use only. It's stream is embedded into Repetier Server, Duet Web Control, Grafana, Ins...
Monitoring and alerting
Hangprinter consists of a lot of electronic components which can be monitored in different ways. Due to its network infrastructure and device use there are some web pages to get metrics or general information from. The target of Trikarus infrastructure is to m...
