How to Install and run Airodump-ng on Kali Linux

Airodump-ng is included in the Aircrack-ng package, and raw 802.11 frames are used to capture the package. Airodump-ng for WEP IV collection is suitable for use with Aircrack-ng. This tool can record the coordinates of the access points discovered through a GPS receiver connected to the computer. In this article, we try to learn How to Install and run Airodump-ng on Kali Linux. You can visit the packages available in Eldernode to purchase a Linux VPS server.

Tutorial Install and run Airodump-ng on Kali Linux

Airodump-ng is a wireless packet recording tool for aircrack-ng. As mentioned, airodump-ng is using to record packages of raw 802.11 frames in order to use them using aircrack-ng. Also, if you have a GPS receiver connected to a computer, airodump-ng can record the coordinates of access points. Airodump-ng writes a text file that contains details of all access points and clients seen. In addition to the explanations given, airodump-ng writes several files that include details of all access points and clients seen. Follow us in the continuation of this tutorial.

Install and run Airodump-ng on Kali Linux

Interestingly, this program is already installed on Kali Linux but the Airodump-ng tool is located inside the aircrack-ng service. For this reason, the prerequisite for using Airodump-ng is the installation of aircrack-ng. After you have successfully installed aircrack-ng, you can use the following command to get acquainted with the features of the Airodump-ng tool.

By executing the above command, you will see the following output. You can execute the tasks you want by executing any of the following commands in the Airodump-ng tool.

Use Airodump-ng on Kali Linux:

usage: airodump-ng <options> <interface>[,<interface>,…]

Options:
–ivs: Save only captured IVs
–gpsd: Use GPSd
–write <prefix> : Dump file prefix
-w: same as –write
–beacons: Record all beacons in dump file
–update <secs> : Display update delay in seconds
–showack: Prints ack/cts/rts statistics
-h: Hides known stations for –showack
-f <msecs> : Time in ms between hopping channels
–berlin <secs>: Time before removing the AP/client from the screen when no more packets are received (Default: 120 seconds)
-r <file> : Read packets from that file
-x <msecs> : Active Scanning Simulation
–manufacturer: Display manufacturer from IEEE OUI list
–uptime: Display AP Uptime from Beacon Timestamp
–wps: Display WPS information (if any)

–output-format

<formats> : Output format. Possible values: pcap, ivs, csv, gps, kismet, netxml, logcsv
–ignore-negative-one: Removes the message that says
fixed channel <interface>: -1

–write-interval

<seconds> : Output file(s) write interval in seconds
–background <enable> : Override background detection.

Filter options:

–encrypt <suite> : Filter APs by cipher suite
–netmask <netmask> : Filter APs by mask
–bssid <bssid> : Filter APs by BSSID
–essid <essid> : Filter APs by ESSID
–essid-regex <regex> : Filter APs by ESSID using a regular expression
-a : Filter unassociated clients

By default, airodump-ng hopps on 2.4 GHz channels. So you can record it in other channels using the options below:

–ht20: Set channel to HT20 (802.11n)
–ht40- : Set channel to HT40- (802.11n)
–ht40+ : Set channel to HT40+ (802.11n)
–channel <channels> : Capture on specific channels
–band <abg> : Band on which airodump-ng should hop
-C <frequencies>: Uses these frequencies in MHz to hop
–cswitch <method> : Set channel switching method
0: FIFO (default)
1: Round Robin
2: Hop on last
-s: same as –cswitch

–help : Displays this usage screen

What are the fields displayed when running Airodump-ng?

In this section, we intend to explain the fields displayed in this section by providing an example of running airodump-ng. Look at the picture below:

The first line shows the current channel, elapsed running time, current date, and optionally if a WPA/WPA2 handshake was detected. It should also be noted that “WPA handshake: 00:14:6C:7E:40:80” indicates that a WPA/WPA2 handshake was successfully captured for the BSSID. The following is an explanation of each of these fields:

BSSID: MAC address of the access point. In the Client section, a BSSID of “(not associated)” means that the client is not associated with any AP.

PWR: Signal level reported by the card.

RXQ: Using this command, you can receive Quality as measured by the percentage of packets (management and data frames) successfully received over the last 10 seconds.

Beacons: Number of announcements packets sent by the AP.

# Data: Number of captured data packets, including data broadcast packets.

#/s: Number of data packets per second measure over the last 10 seconds.

CH: Channel number taken from beacon packets.

MB: Maximum speed supported by the AP.

ENC: Encryption algorithm in use.

CIPHER: The cipher detected.

AUTH: The authentication protocol used.

ESSID: This shows the wireless network name.

STATION: MAC address of each associated station searching for an AP to connect with.

Rate: Station’s receive rate, followed by transmitting rate.

Lost: The number of data packets lost over the last 10 seconds based on the sequence number.

Packets: The number of data packets sent by the client.

Notes: Additional information about the client, such as captured EAPOL or PMKID.

Probes: These are the networks the client is trying to connect to if it is not currently connected.
