添加监听端口
网卡默认是managed模式，我们添加一个monitor模式的类型接口,这样我们就可以使用无线网卡进行无线数据包的侦听。
iw dev wlan0 interface add wlan0mon type monitor
查看接口列表，可以看到多了一个wlan0mon

lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry short long limit:2 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
wlan0mon IEEE 802.11 Mode:Monitor Tx-Power=20 dBm
Retry short long limit:2 RTS thr:off Fragment thr:off

删除monitor模式的接口
iw dev wlan0mon interface del
抓包
首先我们先把网卡置于up状态
ifconfig wlan0mon up
然后使用wireshark选择该网卡就可以进行抓包了
