This is a copy of a post I made to photo.stackexchange.com. I felt I should put it here due to the more technical side of the question, and it barely relating to photography.
I have a Nikon D5300 with built in WiFi. I'm interested in tinkering/hacking with its network protocol and transferring photos wirelessly.
After looking into the network protocols and ports, I found this:

It talks about how you can use FTP on some WiFi chips in different camera models, but I'm not sure if it includes mine.
I know there are two ports used for the connection; one is 15740 to transfer the photos, and one is 5353 to connect. I also found that the chip uses the Media Transfer Protocol (MTP).
Is there a way I can directly browse or transfer pictures from Ubuntu?
