Hi, Could somebody help in figuring out why PF configuration meant to prevent brutal SSH attacks doesn't work.
Here are the relevant parts: /etc/ssh/sshd_config PasswordAuthentication no MaxAuthTries 1 /etc/pf.conf block in log on $wan_if table <abusive_hosts> persist block drop in quick from <abusive_hosts> pass quick proto tcp to $wan_if port ssh keep state \ (max-src-conn 10, max-src-conn-rate 9/60, overload <abusive_hosts> flush global) I would expect if somebody tried to make more then 9 connections a minute would have been blocked. But it's not the case: Feb 7 19:20:03 castor sshd[21416]: Invalid user peyton from 113.185.0.16 Feb 7 19:20:06 castor sshd[21418]: Invalid user lindsey from 113.185.0.16 Feb 7 19:20:10 castor sshd[21420]: Invalid user ashlyn from 113.185.0.16 Feb 7 19:20:13 castor sshd[21422]: Invalid user carly from 113.185.0.16 Feb 7 19:20:17 castor sshd[21424]: Invalid user marissa from 113.185.0.16 Feb 7 19:20:20 castor sshd[21426]: Invalid user gracie from 113.185.0.16 Feb 7 19:20:24 castor sshd[21428]: Invalid user sierra from 113.185.0.16 Feb 7 19:20:27 castor sshd[21430]: Invalid user lillian from 113.185.0.16 Feb 7 19:20:31 castor sshd[21432]: Invalid user jillian from 113.185.0.16 Feb 7 19:20:34 castor sshd[21434]: Invalid user reagan from 113.185.0.16 Feb 7 19:20:37 castor sshd[21436]: Invalid user shelby from 113.185.0.16 Feb 7 19:20:41 castor sshd[21438]: Invalid user amelia from 113.185.0.16 Feb 7 19:20:44 castor sshd[21442]: Invalid user jada from 113.185.0.16 Feb 7 19:20:48 castor sshd[21444]: Invalid user kendall from 113.185.0.16 Feb 7 19:20:51 castor sshd[21446]: Invalid user courtney from 113.185.0.16 Feb 7 19:20:54 castor sshd[21448]: Invalid user brooklyn from 113.185.0.16 Feb 7 19:20:58 castor sshd[21450]: Invalid user autumn from 113.185.0.16 Feb 7 19:21:01 castor sshd[21452]: Invalid user mary from 113.185.0.16 What did I miss?
