I see hits from various scanners/bots my Apache logs a lot. It's kind of funny, the only thing globally exposed on this server are ports 80 and 443 (different servers, same 3 domains atm) and a ping server (a default tcp ping-like server in Go)

I also have a port that I use for my webcam experiments and various other things, service in play today varies. =)

My ssh port is well secured, on a separate FW zone with only my home IP allowed ingress. When my internet goes down at home, I usually lose ssh access for a while too. Sending to my rtmp server is the same, one IP allowed, no others.
