Sometimes. I have found portsentry to be a useful tool in 
blocking/annoying port scan hackers.
Basically, it listens on handful of ports where active services are not 
running. When portsentry detects a connection, that ip is nullrouted for 
a period of time using iptables or ipchains thus preventing any further 
attacks. Check it out.
