["Abilash Praveen" <abilashpraveen82 hotmail com>]

Hi,

I have many failed login attempts on my server. I want to block all ip that produce more than 20 failed logins at a time. How do i go about it? Please note that i want to block ips on fail login for all services, ftp, ssh, telnet, mail, etc.

Thanks in advance,
