I'm currently tinkering with join to extend my "network management" solution. Setup currently is as follows: I have a router that has served it's time, slapped openwrt on it. On this router I have a small script listening on a random port chosen on script startup, router itself is the only publicly exposed system. I push a request to this port with a json object, containing device, a hash of a currently hardcoded password and the command. Depending on the command, various scripts get executed, depending on password and command in the json object. I have yet to find a way to enable two-way-communication yet. I've wrapped a lot of this up in a nice little flask app serving up a web interface in my LAN for adminstration and stuff, but I'd like to have confirmation, and this is where I have the most issues. I'm interested in using join as a transport, but I need to find a surefire way to communicate with my router, so I need to have it registered on my device... Is there something I can do for that?
