Subject: Block access for ips

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,
Abilash Praveen M

p.s: I'm on a FC4
