Installing

This version has more dependencies/libraries required than previous versions to be compiled. See INSTALLING file for more information

OpenWrt Devices

You can use airodump-ng on OpenWrt devices. You'll have to specify prism0 as interface. Airodump-ng will automatically create it. Rq: Aireplay DOESN'T work on OpenWrt (2.4 kernel) with broadcom chipset since the driver doesn't support injection. It may work with 2.6 kernels >= 2.6.24 (kamikaze 8.09+ custom-built).

Known bugs:

Drivers

Madwifi-ng
----------

The cause of most of these problems (1, 2 and 3) is that Madwifi-ng cannot easily change the rate in monitor mode.
Technically, when changing rate while in monitor mode, the raw socket gets invalidated and we have to get it again.
Madwifi-ng is getting replaced by several drivers: ath5k, ath9k and ar9170.


Problem 1: No client can associate to an airbase soft AP.
Solution: Use a more recent driver. Madwifi-ng has been deprecated for years.


Problem 2: When changing rate while you are capturing packet, airodump-ng stalls
Solution 2: Restart airodump-ng or change rate before starting it.

Problem 3: After some time it stops capturing packets and you're really sure no network managers are running at all.
Solution 3: That's a known bug in the driver, it may happen at any time (the time before it fails can vary a lot: 
            from 5 minutes to 50 or even more). Try (as root) unloading completely the driver with 'madwifi-unload'
            and then run 'modprobe ath_pci autocreate=monitor'.
	  

Problem 4: When creating a new VAP airodump-ng takes up to 10-15 seconds to see the first packet
Solution 4: It's the behavior of madwifi-ng, don't worry (... be happy ;)).


Orinoco
-------

Problem: BSSID is not reported correctly or is 00:00:00:00:00:00 or signal is not reported correctly.
Solution: None. Consider replacing your card, orinoco is really really old.

Aircrack-ng

Aireplay-ng
-----------

Problem: Fakeauth on a WRT54G with WEP (shared authentication) doesn't work.
Solution: None at this time (we'll try to fix it in an upcoming release).


Airolib-ng
----------

Problem: On windows only, opening/creating a database doesn't work when airolib-ng is in directories containing
         special characters like 'ç', 'é', 'è', 'à', ... (directories containing spaces are not affected).
Reason: It's an SQLite issue.
Solution: Rename the directory or move the database into another directory.


Airodump-ng
-----------

Problem: Airodump-ng stops working after some time.
Solution 1: You may have a network manager running that puts back the card in managed mode. 
            You'll have to disable it (the fastest solution is killing the process) then restart airodump-ng.
Solution 2: See Problem 3 of Madwifi-ng.

Problem: On windows, it doesn't display a list of adapters like the old 0.X
Solution: It requires you to develop your own DLL.

Problem: Handshake is not captured/detected
Reason: You might be too far and your signal is bad (or too close with a signal too strong).
        Another possibility is that Airodump-ng didn't detect the handshake properly due to
        being far apart in the capture.
Solution 1: Check out our tutorial 'WPA Packet Capture Explained' in the wiki.
Solution 2: Try running Aircrack-ng on your capture, it might detect the capture.
Solution 3: Check out our wpaclean tool.
Note: It will be fixed in an upcoming release.

Cygwin
------

Problem: /usr/include/sys/reent.h:14:20: fatal error: stddef.h: No such file or directory
Solution: It happens because the gcc and g++ version are different. Make sure they are the same.

Sample files

wep.open.system.authentication.cap: It shows a connection (authentication then association) to a WEP network (open authentication).

wep.shared.key.authentication.cap: It shows a connection (authentication then association to a WEP network (shared authentication). The difference with open authentication is that the client has to encrypt a challenge text and send it back (encrypted) to the AP to prove it has the right key.

wpa.cap: This is a sample file with a WPA handshake. It is located in the test/ directory of the install files. The passphrase is 'biscotte'. Use the password file (password.lst) which is in the same directory.

wpa2.eapol.cap: This is a sample file with a WPA2 handshake. It is located in the test/ directory of the install files. The passphrase is '12345678'. Use the password file (password.lst) which is in the same directory.

test.ivs (http://download.aircrack-ng.org/wiki-files/other/test.ivs): This is a 128 bit WEP key file. The key is AE:5B:7F:3A:03:D0:AF:9B:F6:8D:A5:E2:C7.

wep_64_ptw.cap (http://dl.aircrack-ng.org/ptw.cap): This is a 64 bit WEP key file suitable for the PTW method. The key is '1F:1F:1F:1F:1F'.

wpa-psk-linksys.cap: This is a sample file with a WPA1 handshake along with some encrypted packets. Useful for testing with airdecap-ng. The password is 'dictionary'.

wpa2-psk-linksys.cap: This is a sample file with a WPA2 handshake along with some encrypted packets. Useful for testing with airdecap-ng. The password is 'dictionary'.

wps2.0.pcap: This is a test file with WPS 2.0 beacon.

password.lst and password-2.lst: This is a sample wordlist for WPA key cracking. More wordlists can be found at https://www.aircrack-ng.org/doku.php?id=faq#where_can_i_find_good_wordlists

password.db This is a sample airolib-ng database for WPA key cracking.

pingreply.c Replies to all ping requests. Useful for testing sniffing/injecting packets with airtun-ng.

Chinese-SSID-Name.pcap Contains a beacon with an SSID displayed in Chinese.

verify_inject.py Testing DNS requests using airtun-ng.

n-02.cap: This is a test file with 802.11X-2004 AES-128-CMAC handshake. Useful for testing with aircrack-ng. The password is 'bo$$password'.

test-pmkid.pcap: This is a test file with PMKID. Passphrase for 'WLAN-771698' is 'SP-91862D361'

test1.pcap: This is another test file with PMKID. Passphrase for the network 'ogogo' is '15211521'

StayAlfred.hccapx: Hashcat HCCAPx file with WPA handshake. Passphrase for 'StayAlfred' ESSID is 'staytogether'

wpa3-psk.pcap: WPA3 PSK SAE authentication. Passphrase for the network 'WPA3-Network' is 'abcdefgh'

3.pcap Allows to reproduce issue #672 (Fixed by commit 312bb64)

floating_point_exception.pcap Allows to reproduce issue #672 and triggers a SIGFPE (Fixed by commit 312bb64)

80211ad_beacon.pcap DMG Beacon (802.11ad)
