John L., John V., Ian, Roy, Morris, Andrew, John S., Stephan, Bogdan, thanks VERY MUCH for responding! Much appreciated!
John V., " Iptables is the elegant, but complex way of limiting connections. Newer versions of the kernel have an ipt_recent module that allows you to detect and temporarily (or permanently) shutdown offending IP addresses based on how many times in a given duration that a connection has been made. This is one way to solve the problem and I recommend it if you are interested in learning firewalling. " Looks like IPTABLES it is! My knowledge on IPTABLES is zero but there is always a first time for everything! I am however interested in this ipt_recent. I am using kernel 2.6. I'll do some reading on this also and remove my SSH port to a non-default port. Ian: I am using psad and portsentry for monitoring. The throttling feature is quite interesting. I'll do some reading on this more and will also investigate the temporary banning of IP's based on the number of trials. Thanks and regards to all!
