Let's now take a look at how to bypass Open Authentication:
- We will first set our lab access point Wireless Lab to use Open Authentication. On my access point, this is simply done by setting Security Mode to Disable Security:
- We then connect to this access point using the
iwconfig wlan0 essid Wireless Labcommand and verify that the connection has succeeded and that we are connected to the access point. - Note that we did not have to supply any username/password/passphrase to get through Open Authentication.
