## Who is attacking your server?
The lastb command in Linux displays a list of failed login attempts by users. It retrieves the information from the /var/log/btmp file, which records unsuccessful login attempts. We can use lastb to generate a list of crackers' IP addresses, and then generate a configuration file for iptables to block them.
