Are you running any services on your system that are accessible to the outside world? The only daemon I know of personally that would do this is DenyHosts, which is meant to stop SSH brute force attacks. Do you have an SSH server and DenyHosts running on the machine?

Yes, I am running an SSH server on that server. It is accessible from the outside but it has been protected, i.e., root login is not allowed via SSH, normal user login is disabled after 3 unsuccessful attempts, and so forth. However, I had never heard about the DenyHosts daemon before.
