In First Post i had told you how to make Monitor Mode mon0 , Now i am start sniffing packet but a large amount of packets come here in list so how to found any selected packet , the answer of this question is Filter who help you find your packet from a large collection.

First i am telling you type of Frame. I know first thing which come in your mind is "Hey, What the f**king things is this ?"

I thought everybody know our internet is a wlan (Wide Local Area Network) , you know a wlan communicate on Frame so i thing now you know about this f**king thing.

First i am telling you about types of wlan frame , there are three types of wlan frame :

1. Control Frame : Ensuring proper communication between the access points and wireless users.

2. Management frame: Maintaining Communication between Access points and Wireless users.

3. Data frame: Carry Data between Access Point and Wireless Users .

Now i think you know about Frame Very well , i am going to start practical .

1. If you want to see only captured Management frame then Enter in filter below write code :

Code:

wlan.fc.type==0

And Press Apply button ,for example see below pic...

2. If you want to see only captured wlan control frame then type in filter box this expression :

Code:

And then press Apply button , see below pic...

3. For view the Data Frame type expression which one write below....

Code:

wlan.fc.type=2

And again press Apply button , see below pic...

4. If you want see any sub-type with any frame type then write below expression :

Code:

(wlan.fc.type=0)&&(wlan.fc.subtype==8)

Change Number according to your selection , see below pic...

You can also use TCP ,POP , UDP and more as filter.
