The script is shown below, any ideas? Basically I need to drop any connection attempts shown as authentication failures, am I trying to re-invent the wheel?
Pretty much. The preferred method of dealing with SSH dictionary attacks is:a) Configure your SSHD to only allow authentication via shared keys. That way, a dictionary attack can never succeed.
b) Use the 'Limit' built-in action to limit the rate of SSH connection attempts from individual IP addresses (http://www.shorewall.net/PortKnocking.html#Limit).
