airodump-ng is a part of the Aircrack-ng suite, a set of tools for auditing wireless networks. airodump-ng is specifically designed for capturing and displaying information about wireless networks, including details about nearby access points (APs) and connected clients.

Here are some common commands and features associated with airodump-ng:

  1. Capture Wireless Network Information:

    airodump-ng <interface>

    Replace <interface> with the name of your wireless interface. This command captures and displays information about nearby wireless networks.

  2. Specify a Capture File:

    airodump-ng -w <output-file> <interface>

    This command allows you to specify an output file for storing the captured data. Replace <output-file> with the desired filename.

  3. Filter by BSSID (AP MAC Address):

    airodump-ng --bssid <BSSID> -c <channel> -w <output-file> <interface>

    This command filters the capture to a specific AP (access point) using its BSSID (MAC address). Replace <BSSID> with the target AP's MAC address, <channel> with the channel number, and <output-file> with the desired filename.

  4. Filter by ESSID (Network Name):

    airodump-ng --essid <ESSID> -c <channel> -w <output-file> <interface>

    This command filters the capture to a specific network using its ESSID (name). Replace <ESSID> with the target network's name, <channel> with the channel number, and <output-file> with the desired filename.

  5. Filter by Both BSSID and ESSID:

    airodump-ng --bssid <BSSID> --essid <ESSID> -c <channel> -w <output-file> <interface>

    This command allows you to filter the capture based on both BSSID and ESSID.

  6. Show Client Information:

    airodump-ng --bssid <BSSID> -c <channel> --showack -w <output-file> <interface>

    This command displays information about associated clients for a specific AP.

airodump-ng is commonly used in combination with other tools from the Aircrack-ng suite, such as aireplay-ng for packet injection and aircrack-ng for cracking WEP or WPA/WPA2 keys. As with any security tool, it's crucial to use airodump-ng responsibly and legally, obtaining proper authorization before testing or auditing any wireless networks. Unauthorized access to networks or systems is illegal, and ethical considerations should always be a priority.
