Ok. Because everyone here did such a fantastic job with my last question, I'll "reward" you with another one that's completely unrelated.
I just spent a night in a pleasant motel. As is my habit, I visually scanned our room for cameras and then surveyed the WiFi network using nmap for anything that looked suspicious.
Besides the usual routers and network printers and guests' iPhones, here were about 14 Linux SSH servers that looked like this:
Code:
Nmap scan report for 192.168.1.119
Host is up (0.0056s latency).
Not shown: 99 closed ports
PORT STATE SERVICE
22/tcp open ssh
What could those SSH servers be doing? There were around 14 rooms in the motel, so it would make sense they were in use in each room, but I couldn't see any likely devices. The thermostat was old and definitely not "smart" and I don't think the air conditioner itself (Mitsubishi Mr. Slim) has an OS. The in-room phones definitely pre-dated the digital age (well, technically, they were touch tone).
Is there any explanation that makes sense here?
There was another host on the network that made me curious, since it was running all kinds of services, including X11 through port 6000:
Code:
Nmap scan report for 192.168.1.134
Host is up (0.013s latency).
Not shown: 994 closed ports
PORT STATE SERVICE
80/tcp open http
443/tcp open https
4443/tcp open pharos
6000/tcp open X11
7676/tcp open imqbrokerd
9090/tcp open zeus-admin
