Step 3:
Goto -> Sniffer Tab and click Configure in the main menu to configure your packet listening adapter.

Step 4:
Select the appropriate network adapter for your network that you want to sniff the packets for plain-text passwords. And Click Ok.

Step 5:
Click the Green Adapter icon as shown below. This means that you just configured the adapter and now you are turning it ON.

Now select the APR tab below as shown and now first click on the right side upper pane area. When you click that area the blue plus (“+”) icon will get enabled. Press that blue plus (“+”) icon.

Step 7:
This is very interesting step. Now we need to select the router`s IP address and click ok. This means that we want to listen to every packet that is sent to router. If we select any other IP address in our LAN network then we can listen to only that particular HOST on the network. Since the router responds to all the request of HOSTS connected in a LAN. Thus we can listen to all the HOSTs.

Step 8:
Now click the Yellow Circle icon as shown. This means that we are starting ARP poisoning.

Step 9:
We can see that in the upper right panel there is an IP address of our router and when we press that Yellow Circle icon (button), it performs ARP poisoning.

Step 10:
Now click the password tab which is at the bottom. We can see that we are getting passwords of HTTP i.e. plain text session in our LAN network.
