    i got a lot of Brute force detection on myserver.
    Code:
    ED -- TOO MANY FAILURES -- IP TEMP BANNED
    Mar 20 07:33:11 six PAM-hulk[4414]: Brute force detection active: 580 LOGIN DENIED -- TOO MANY FAILURES -- IP TEMP BANNED
    Mar 20 07:33:15 six PAM-hulk[4418]: Brute force detection active: 580 LOGIN DENIED -- TOO MANY FAILURES -- IP TEMP BANNED
    Mar 20 07:33:18 six PAM-hulk[4422]: Brute force detection active: 580 LOGIN DENIED -- TOO MANY FAILURES -- IP TEMP BANNED

    Hello,

    There are a number of valid suggestions at: http://forums.cpanel.net/f34/ip-ban-server-128005.html

    For the entire server you might try using the /etc/host.deny file or iptables: iptables -A INPUT -s x.x.x.x -j DROP

    For a single account you might want to use cPanel >> Security >> IP Deny Manager

    Best Regards,
    Anne

    If you would like to ban a specific IP for a period of time after a set number of login failures, you can try something like the following in iptables:

    Ban IP after 3 incorrect login attempts | Switchlink

    Simply change the service port to whichever service you need to be blocked.

    Otherwise, if WHM > cPHulk Brute Force Protection isn't working to block as long as you would like, you can consider trying something like fail2ban (Fail2ban).
