Why so many bots?
You can reduce the noise a lot by moving ssh to a non standard port. Security through obscurity isn't actually security, but it will reduce the number of attempts you receive. Another thing I like to do is put Endlessh on the standard port 22. That way as bots go by they will get stuck or at least slow down on that connection.

Even this requires you to successfully guess the username and password correctly, and if it's just not the default most people won't bother brute forcing further. Sidenote: you can use endlessh on a computer and port forward port 22 to trap scanners that scan the entire internet for open ssh ports to exploit.

The fun way is moving your ssh port somewhere else and installing endlessh to f the bots.

Keep it tight everyone! This is a day of sshd logs from a proxy server in China pinging my SSH server and trying every username imaginable. Does anyone have any tips to increase security?
But, as a prank to Chinese hackers, what I did on my system was to run endless ssh. It keeps the ssh client busy as it slowly sends the ssh banner. I modified the code to send strings like:
Install https://github.com/skeeto/endlessh to run on eg. port 22233 (in /etc/endlessh.conf)
this'll help
- Any app out there to trap port scanners?
- Mein Server wird für Bruteforce Attacken genutzt, was kann ich tun?

Just so we're clear - you do all know your passwords, right?
I have port 22 open on my home server, but I have this running on that port: https://github.com/skeeto/endlessh. It's quite wild seeing the amount of connection attempts for this.
