Title: Unbreakable SSH: Securing Your Server from Brute-Force Attacks

"Hey guys, has anyone else experienced brute-force attacks on their SSH server? I've seen a few friends get owned by bots trying to guess their private keys. I'm looking for some solid strategies to harden my SSH config and stop these attacks in their tracks."

"Thanks for sharing this OP, always good to brush up on SSH sec measures. One thing I've found useful is setting up 2FA via Google Authenticator or YubiKey. Has anyone else used these methods to prevent brute-force attacks?"

Yea i use fail2ban on my VPS, it's been a game changer for blocking IP's that get too many login attempts. Also, making sure to use a strong passphrase and enabling 2FA never hurts. Has anyone else had any luck with the Google 2-Step Verification for SSH?

"Dude, I use U2F keys on my servers and they've been a game-changer for SSH security. No more password managers or 2FA codes, just plug in the key and you're good to go. Zero chance of brute-force attacks with this setup."
