block specific ip addresses
I'm allowing port 22 to pass through my router so I can ssh into my box remotely. Lately, I've noticed an IP address out there who keeps trying random username / password combos on my box. He/she never guesses correctly, but it's a risk. How can I block this IP (or, say, only allow specific IPs) from my linux box? Or is this something I should do from the router?
