# Ensure you start your firewall setup on each VM from the default iptables-services rules. You'll lose marks if you don't have a functional firewall on lin1a1 and on lin2a1.

SSH brute-force attack (10 marks) ==
Create at least 5 users on lin2, give some of them simple/ common names ( like "john") and simple or relatively-simple passwords. If you have a complex root password - you might want to change that to something simpler too.# Find some software to perform a brute-force SSH login attack on lin2 from lin2a2.# Run the attack. Record how long it took, and what the results were. If it fails to find usable credentials for you - make sure you have an explanation for why that was.
