What are the main functions of airodump?

Airodump-ng is a tool used for capturing and analyzing wireless network data packets, with its main functions being:

1. Packet capture: Airodump-ng can capture packets in a wireless network, including management frames, control frames, and data frames. It can monitor the wireless network card and save the captured packets to a file.
2. Network detection: Airodump-ng can scan surrounding wireless networks and display information such as their SSID (Service Set Identifier), MAC address, signal strength, and data rate. By detecting wireless networks, users can learn about the nearby wireless network environment.
3. Client tracking: Airodump-ng is able to track client devices associated with a specific wireless network. It can display information such as the MAC address, signal strength, and data transfer rate of clients connected to the target network.
4. WEP/WPA-PSK key cracking: Airodump-ng can collect enough data packets to crack the password of a wireless network encrypted with WEP (Wired Equivalent Privacy) or WPA-PSK (Wi-Fi Protected Access Pre-Shared Key). It can gather handshake packets and analyze them using password cracking tools to break into the network.
5. Packet filtering and analysis: Airodump-ng can filter and analyze captured packets based on various criteria such as source MAC address, destination MAC address, protocol type, and packet length. It can assist users in network traffic analysis and troubleshooting.

Overall, Airodump-ng is a powerful wireless network analysis tool that can be used to detect surrounding wireless networks, track client devices, capture and analyze data packets, and support WEP/WPA-PSK key cracking.
