This lesson focuses on scanning in the Linux environment and focuses on two commands that can be used for this purpose:
P0f is a passive scanner designed to tell things about a machine. It informs about distant hosts and targets by analyzing packets. Nmap is the main tool for scanning and very powerful. It can do many things; it scans a host and tells what ports are open and what those ports are doing. This lesson also discusses scanning techniques: - Sinconnect: most commonly used, creates a connection with servers.
- Ac: sent at host machines.
- UDP: scans UDP ports, sends a packet and hopes to receive something back.
- OS connection: sends out data and you can set the speed
- Service detection
