Fortunately my VPS (oracle) has set SSH authentication to be default. Disallowing root login sounds good, gotta try that as well.

Thanks, I will try fail2ban. I am using ED25519 for ssh keys, it seems like it’s the best defense on the ssh side. Do you happen to know why this kind of attack is so prevalent?

Thanks a lot! Geoblocking makes a lot of sense, will try!

Thanks, though Shorewall looks intimidating. Do you have any good resources to go over how to set it up?

It seems permanently unavailable, how did you get an instance?

Thanks, I am running rootful containers so I don’t think this applies.

Thanks, but I am worried about relying on small repo like this. EDIT: But it did made me realize Goodnotes support WebDAV, thanks!
