sshd - Invalid user ....

I've written a couple of entries about my anoyance and solving the issue with "Invalid user", after I started running my script it seams that there are 40 ipaddress which actually is causing this.

If you want to get ridge of this, then either run my script, or start by blocking the following ipaddresses:

By using iptables: # iptables -A INPUT -i <interface> -s IPADDRESS -p tcp --dport 22 -j DROP

Then you should hopefully see that you number of "Invalid user" entries in /var/log/secure will go down. If not start doing something active.
