Recently, an intrepid and curious Tesla owner found a hidden four-pin connector, and with a hunch and some trial-and-error work discovered that it is in fact an ethernet port, and wired up a standard ethernet cable to connect to it.
What he discovered next is notable for how strangely familiar it all is to anyone with even a passing knowledge of computer networking:
The car’s internal 100 Mbps, full duplex ethernet network consists of 3 devices with assiged IP addresses in the 192.168.90.0 subnet, the center console, dashboard/nav screen and one more unknown device. Some ports and services that were open on the devices were 22 (SSH), 23 (telnet),53 (open domain), 80 (HTTP), 111 (rpcbind), 2049 (NFS), 6000 (X11). Port 80 was serving up a web page with the image or media of the current song being played. The operating system is modified version of Ubuntu using an ext3 filesystem.
It’s really odd just how, well, normal all this feels — it’s just like any home or office network. They’re using it in some interesting ways — for example, the current song playing artwork is being served to the center large display simply like normal web traffic."
