A. You can use DenyHosts – a Python based script that analyzes the sshd server log messages to determine what hosts are attempting to hack into your system. It is an utility to help sys admins thwart ssh crackers. It also determines what user accounts are being targeted. It keeps track of the frequency of attempts from each host. It will automatically blocks ssh attacks by adding entries to /etc/hosts.deny. DenyHosts will also inform Linux administrators about offending hosts, attacked users and suspicious logins.
