Looks like i was quite lucky. At the moment, i was looking at the server notifications and fail2ban started screaming.
Almost 30 different IP addresses were blocked for ssh attack. And the locations are all around the world.
It was a server exposed online via some subdomain. Some ports were open, including 22. Is this something to be expected always?
What do the guy expect?
Does it make sense to report this to DigitalOcean as several of those IPs belong to DO?
