does RPCWI have a network port signature? #603

Closed BETLOG closed 3 years ago

BETLOG commented 3 years ago

Does RPCWI have some kind of unique response to queries that I could use to determine which LAN machines actually have it installed and running on them? Ideally I'd like to be able to spend no more than 1 second querying each machine with something like nc, and conclusively determine if RPCWI is operational on them or not.

If you use nc to the port that the web server is supposed to be running on to determine that port is open then doing a wget from ip/html/status_mjpeg.txt would return a single word with the current status which could be "Error" "halted" "image" "tl_video" "video" "tl_md_video" "timelapse" "ready" "tl_md_ready" "md_ready"

If the web server is running but no RPCWI installed then you would get file not found error.
