    Hi :)

    George please remove from:
    Code:
    [nginx-auth]
    the:
    as it is included and checked from:
    Code:
    [nginx-auth-main]
    Also this one is not duplicated:
    Code:
    [shells]
    enabled = true
    filter = shells
    action = csfdeny[name=shells]
    #action   = cloudflare
    logpath = /home/nginx/domains/*/log/access.log
              /var/log/nginx/*.access.log
    bantime = 604800
    maxretry = 1
    findtime = 86400
    Can you please duplicated so we will have the logs separated?

    Thank you !

    Now all are working great for me when i test it from scratch :)

    Don't know if it is possible to get at the Cloudflare ban as a comment the same as csf comment...

    For example Fail2ban and the jail name so we will know why the ip was banned (from the cloudflare panel) without going to the server and grep the ip or check it using the fail2ban status option.... ?

    Hi

    I tested this last month on centos 7 and it worked perfectly it was like magic lol, and i was hoping if there is a version for centos 6 as i'am swarmed with bots to the point where i can't even use my own website.

    Oh my, just got confused out.

    Okay, sorted out the fail2ban and it's working, thank you.

    What about the virtual host "location" to catch the forums' login and register and also the login in the admin panel to add a limit_req_zone? Can't figure it out by myself. o_O

    For folks testing my Centmin Mod fail2ban implementation, I've updated it to detect log4j vulnerability scans for Centmin Mod Nginx log inspection. Details in at Update to support log4j vulnerability scans · Issue #2 · centminmod/centminmod-fail2ban. You can see an example of fail2ban detecting log4j vulnerability scans on Centmin Mod Nginx server with my fail2ban implementation installed at GitHub - centminmod/centminmod-fail2ban: fail2ban setup for centminmod.com LEMP stack with CSF Firewall. FYI, while doing testing, it actually caught a real vulnerability scan too!

    There is no support for Centmin Mod fail2ban implementation, so you'd generally be on your own to configure and troubleshoot for your needs.
