Hello, Too many break-in attempts come from cracked Windows boxes running script bots to make reporting these attempts practical, so I changed my ssh port to a non-standard one. Now, if I see a break-in attempt, I block the /21 the attacking IP falls into and report it to the relevant ISP/network admin because I know a black hat has taken a personal interest in my network.
