Nice story, Phil. Thanks for sharing it with us.
Thanks for the great article. I have learned some good stuff from it. You also reminded me of the lastb command which I had completely forgotten.
I get far fewer hack attempts recorded by wtmp than you do, primarily because I use Fail2Ban on my firewalls. I have had as many as 300 or so IP addresses blocked by Fail2Ban at one time. Usually the number is more like a dozen or so, but attacks seem to come in waves.
Thanks again for sharing your expertise.
