While everything looks Ok. Fail2ban status shows running. Yet it appears like something is wrong there. Reason being my mail.warn log files were getting flooded with unwanted traffic and failed attempts. Now after proper activation of fail2ban, the mail.warn log appears to be almost dead slow. It looks very strange that just by correcting fail2ban all the bots have gone away. There is no ban or unban of ips in the fail2ban log. it appears that the events are not getting logged properly. How I can make sure that everything is OK. Thanks.
