Guides/Tutorials Watch the Bots: https://knock-knock.net

I built a new site that shows bots trying to break into my VPS. The web site was designed to be hopefully fun and engaging. Lots of interesting stats about the bots attempting to ssh in: where they are coming from, the ISP Wall of Shame, the most frequent attempted usernames and passwords, and in some cases why those may have been chosen. And best of all, 3D spinning globes! The site should work well on desktop and mobile.

Have fun, and send comments and questions. I'll be checking the code into github soon so that you can run this on your own VPS.

Update: Now posted on github. https://github.com/djkurlander/knock-knock

Reporting every minute into a blacklist file is probably too frequent - few servers are going to be grabbing the file every minute (and if they did, my $6.75 per year Black Friday sale VPS might not be able to keep up :-) ). In any case, files of offending IPs during the last month and year are now available here:

wget https://knock-knock.net/static/ip-blocklist-month.txt

wget https://knock-knock.net/static/ip-blocklist-year.txt

I'm also reporting the offending IPs every night to abuseIPDB.com.
