Why are these ports showing up with a nmap scan?
I just scanned my droplet with nmap:
What is this crap:
135/tcp filtered msrpc
139/tcp filtered netbios-ssn
445/tcp filtered microsoft-ds
593/tcp filtered http-rpc-epmap
I didn't install anything on those ports. I've seen this before with other hosts I've used. My only guess is that it's Microsoft stuff, that is a common problem, and Digital Ocean is blocking it at the router?
