Data Encapsulation refers to the process of encapsulating a Protocol Data Unit (PDU) in a group of protocol headers and tails. In the OSI Layer-7 reference model, each layer is primarily responsible for communicating with the peer layer on other machines. This process is implemented in the Pr
I. Problem Description
Install ubuntu14.04 on the PC and log on as the root user.
When Wireshark is started, the following error dialog box appears:

Select capture by applying packet-capture filtering | Options, expand the window to view the Capture Filter Bar. Double-click the selected interface, as shown, to eject the Edit Interface settints window.The Edit Interface Settings window is displayed, where you can set the packet capture filter condition. If you know the syntax for catching packet filters, enter it directly in the capture filter area. When an error is entered, the Wireshark indicates

BasicIo graphs:
Io graphs is a very useful tool. The basic Wireshark Io graph displays the overall traffic in the packet capture file, usually in the unit of per second (number of packets or bytes ). By default, the x-axis interval is 1 second, And the y-axis is the number of packets at each time interval. To view the number of bits or bytes per second, click "unit" and select the desired content from the "Y axis" drop-down list. This is a ba
One: Filter
Using the Wireshark tool to grab a package, if you use the default configuration, you get a lot of data, so it's hard to find the packet data we're analyzing. So using Wireshark filters is especially important.
Wireshark filters are divided into two types: Display filter, capture filter

Wireshark related tips, wireshark relatedThe Packet size limited during capture prompt indicates that the marked packages are not fully captured. In some operating systems, only 96 bytes are captured by default, the "-s" parameter in tcpdump can be used to specify the number of bytes to be captured. "-s 1500" means that each packet can capture 1500 bytes, '-s 0' indicates the number of TCP Previous segment

The capture session cocould not be initiated (failed to set hardware filter to promiscuous mode) always appears ).
Solution: wireshark-> capture-> interfaces-> options on your atheros-> capture packets in promiscuous mode-set it off.

Change to the hexadecimal dump mode to view the hexadecimal code of the load, as shown in:
Close the pop-up window. Wireshark only displays the selected TCP packet stream. Now we can easily identify three handshakes.
Note: Wireshark automatically creates a display filter for this TCP session.
