3. Step-by-step Guide This demonstration uses Wireshark 2.2.6 on Linux.
a) Start Wireshark
On Linux, you can run the shell script provided below. It starts Wireshark, then configures NIC and the channel for
packet capture.
ifconfig $1 down
iwconfig $1 mode monitor
iwconfig $1 channel $2
ifconfig $1 up
Wireshark&
In the above script, the parameter $1 represents NIC and $2 represents channel. For example, wlan0 in ./xxx.sh
wlan0 6, specifies the NIC for packet capture, and 6 identifies the channel of an AP or Soft-AP.
