I use my own VPS for hosting this website. Hence I get attacked on daily bases. The last time I checked the logs I had more than 2500 attempts to break into my SSH server from around the world. These attackers are mostly opportunistic I believe (or I hope!)
Since the number was very high, I decided to disable password auth and keep publickey auth only. It’s pretty simple.
Step 0: You already have public/private key set and configured in your ssh server and client.
Then you want to edit SHHd config file under:
|
1 |
/etc/ssh/sshd_config |
First make sure you enable public-key authentication or you will lock yourself out!
