[gentoo-user] Blocking login attempts to sshd and vsftpd

[Richard Marza]

I recently check my log files and discovered that there was a dictionary 
attack attempt on my daemons. sshd and vsftpd were the primary targets. Is 
there a script or tool to block the offending IP addresses using iptables. 
Something that checks to see if a minimum of attempts has occured and blocks 
them indefinitely based on that?
