Dynamic DNS (DDNS) functionality on the UDM-SE is provided by Inadyn running as apart of a systemd service (udapi-server.service – Ubiquiti udapi server). Inadyn Triggered (via UDM restart, WAN IP Changed) Inadyn checks local cache for previous WAN IP value if WAN IP == cached IP, do nothing>> Sample output If WAN_IP != cached WAN_IP, […]
The root certificates shipped with iOS 7 are very old at this point, and in some very important cases (Let’s Encrypt IdenTrust DST Root CA X3) have expired. In a lot of cases this will throw an SSL error and prevent whatever site or URL you’re accessing from loading. In my case it was my […]
Edit 2020-10-28: Update docker-compose to v1.27.0+ and you might be able to use IPAM config in a v3 compose file (Link) Docker Compose v3+ does not support IPAM configuration (gateway, ip_range, aux_addresses) of macvlan networks. This network definition used to work in v2, but as v3 targets Docker Swarm use cases, it was removed (NOT […]
It was harder than expected to find a tool to convert HEIC images to JPEG/JPG images, but per usual, I was able to find an open source tool that did this better than a lot of proprietary solutions. The big gotcha with this operation is that a lot of the conversion tools do NOT copy […]

Amcrest to Dahua ipcam mapping
Per this thread some Amcrest cams can utilize the Dahua firmware, which seems to be more likely to get security fixes and updates, and unlocks a few features like (depending on support) available 3rd stream, face detection, IVS, SmartIR & up to 40960 bitrate.https://ipcamtalk.com/threads/how-to-upgrade-amcrest-lorex-to-dahua-firmware-and-get-all-dahua-features.44864 To get your camera’s Alt model number:> http://cam-ip/cgi-bin/magicBox.cgi?action=getSystemInfo Amcrest Dahua IP8M-T2499EW […]

Cockpit and Traefik
HTTP 500, HTTP 404…etc Cockpit’s web server automatically redirects to port 443 with a self-defined SSL certificate. For my use case, I wanted SSL to terminate at Traefik, so I set the backend to point to http and disabled Cockpit’s SSL redirect. Note: To proxy to my host that’s running traefik and docker, I need […]
Down the rabbit hole again trying to revive an old iPhone 4 to pull Podcast duty for the kids. Problem: The charging cable and dock on my Logitech S715i speaker keeps disconnecting. Wiggling the phone around seems to help but it won’t stay charging. Solution: Clean out the charging port. Years of old sticky pocket […]

Docker, Traefik, Jellyfin, DLNA
It seems most media servers (Jellyfin, Emby, Plex, UMS…etc) recommend using docker host networking (-net=host) when running within a container so that it can see UDP traffic on port 1900 for DLNA discovery. This is undesirable for a number of reasons, not the least of which is that a reverse proxy (Traefik, perhaps?) running in […]
