I have my centos fresh server with no problem, I have httpd, named but I get 150 failed logins per 10 minute. I also use Fail2Ban with maxretry 1 findtime 6h. and mod_evasive mod_security default settings just a Bit Tweaked. but When I Disconnect to test and connect back after 10 minute I get 150 failed logins. Fail2ban tells me about 30 - 50 IPs are Banned. I Made my Fail2Ban Config so Strong nothing works, I also found a question on Stackoverflow said to do
pip install pyinotify I installed and set my backend to pyinotify.
I cant even run my Server for 1 - 3 days cause it will get 10 - 15k failed logins.
