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
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.

Wireshark and TcpDump packet capture Analysis and Comparison
Common packet capture analysis tools include Microsoft's Network Monitor and Message Analyzer, Sniff, WSExplorer, SpyNet, iptools, WinNetCap, WinSock Expert, Wireshark, and linux tcpdump.
Today, we conducted an experimental test to compare and analyze two of them. Other users can use Baidu Google to test yiha ^_^.

.
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? Fr = ala0_1_1 introduction to Baidu encyclopedia
Here I will mainly introduce how to use tcpdump on Android
I use a cracked version of G2 and a simulator.
