This article mainly introduces how to check whether the wireless network card supports the monitoring mode in the command line, which has a certain reference value. Interested friends can refer to it. I hope you will learn a lot after reading this article. Let's take a look at it.

Check whether the wireless network card supports monitoring mode

When implementing wireless penetration testing, it is usually necessary to set the wireless network card to monitor all traffic passing through its network card. University tycoon IT talent for many users, do not know how to determine whether their wireless network card supports monitoring, resulting in wasting a lot of time to do useless operations. In order to help users provide productivity, you can use the iw list command to check whether the wireless card supports monitoring before using the wireless card, so as to save unnecessary wasted time. Execute the command as follows:

Iw list

After executing the above command, all the functional information of the device will be output. As follows:

Wiphy phy0

Max # scan SSIDs: 4

Max scan IEs length: 2257 bytes

Max # sched scan SSIDs: 0

Max # match sets: 0

Max # scan plans: 1

Max scan plan interval:-1

Max scan plan iterations: 0

Retry short long limit: 2

Coverage class: 0 (up to 0m)

Device supports RSN-IBSS.

Supported Ciphers:

* WEP40 (00-0f-ac:1)

* WEP104 (00-0f-ac:5)

* TKIP (00-0f-ac:2)

* CCMP-128 (00-0f-ac:4)

* CCMP-256 (00-0f-ac:10)

* GCMP-128 (00-0f-ac:8)

* GCMP-256 (00-0f-ac:9)

Available Antennas: TX 0 RX 0

Supported interface modes: # supported interface modes

* IBSS

* managed

* AP

* AP/VLAN

* monitor # snooping mode

* mesh point

. / / omit part of the content / /.

Device supports HT-IBSS.

Device supports SAE with AUTHENTICATE command

Device supports low priority scan.

Device supports scan flush.

Device supports AP scan.

Device supports per-vif TX power setting

Driver supports full state transitions for AP/GO clients

Driver supports a userspace MPM

Device supports configuring vdev MAC-addr on create.

Supported extended features:

* [RRM]: RRM

* [FILS_STA]: STA FILS (Fast Initial Link Setup)

* [CQM_RSSI_LIST]: multiple CQM_RSSI_THOLD records

* [CONTROL_PORT_OVER_NL80211]: control port over nl80211

Part of the Supported interface modes is included in the output information, and you can view the working modes supported by the wireless network card. If the listed mode has monitor, snooping is supported. Otherwise, it is not supported.

Thank you for reading this article carefully. I hope the article "how to check whether the wireless network card supports the monitoring mode in the command line" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
