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 If the filtered syntax is correct, the green is disp

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

Wireshark cannot capture wireless network card data Solution 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. The capture session cocould not be initiated (failed to set hardware filter to promiscuous mode) always appears

Basic IO Graphs:IO graphs is a very useful tool. The basic Wireshark IO graph shows the overall traffic situation in the capture file, usually in units per second (number of messages or bytes). The default x-axis time interval is 1 seconds, and the y-axis is the number of messages per time interval. If you want to see the number of bits per second or byte, click "Unit" and select what you want to see in the "Y Axis" drop-down list. This is a basic app

is blue. The window is similar, which is very helpful for reading protocol payload, such as HTTP, SMTP, and FTP. 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.

engineering class, we know the network protocol stack, such as physical layer, network layer, Transport layer, application layer:We've seen a few layers of information in the bottom Information Bar of Wireshark:At the SSL layer, decryption is required to see the details of the subsequent Hypertext Transfer layer protocol, which is the result of the operation of the decryption method above.Vii.

thing is Caupture Fileter. Click this button to see some predefined filters. For example, if "http tcp port (80)" is selected, the following Filter string: tcp port http indicates the Filter. Indicates the packet that captures the tcp protocol and port is 80 (the default port of the http protocol is 80 ). 3.

. As an essential tool for system administrators on the internet, tcpdump, with its powerful functions and flexible interception policies, becomes one of the essential tools for every senior system administrator to analyze the network and troubleshoot problems. For tcpdump detailed can refer to the http://baike.baidu.com/view/76504.htm?
