In Android, use TCPDUMP to capture Wireshark to analyze data.GuideIf you want to analyze the network data interaction of an APP in Android, You need to capture packets on the Android mobile phone. The most common packet capture tool is not tcpdump, and tcpdump is used to generate pcap files identified by Wireshark, then, download the pcap file to the computer, load the pcap file with

Wireshark starting from a version of 1.2, the checksum check of the TCP/UDP protocol is not turned on by default. Causes sometimes not to see whether the checksum of the packet is correct, the interface displays "validation disabled" (that is, disable verification):
This is because sometimes the checksum is calculated by the network card, at which time the Wireshark caught by the native sent packet che

Wireshark-Network packet analysis software
The function of the network packet analysis software is to retrieve the network packet and display the most detailed network packet information as far as possible. Wireshark uses WinPcap as an interface to exchange data messages directly with the network card.
Network administrator uses Wireshark to detect
Debugging some of the content of the network, always avoid the need to catch the package, tcpdump is a very suitable tool, this tool can be installed on the server, all the content you need to grasp down, but after the capture it? We also need a tool that can read this package, which is the Wireshark to be introduced.Wireshark is an open source tool, and powerful, easy to use, but under the Mac must have X11 to run, directly installed DMG is not able
To make a long story short, Wireshark has a follow TCP stream feature, which is handy. The drawback is that the extracted stream data does not have time stamps and other information, in the analysis of data delay and packet loss is somewhat inadequate. In this case, a simple follow TCP stream function is implemented with Python, while the TCP information is preserved.The principle is simple and is still based on W
Wireshark is a grab package software, more easy-to-use, in the usual can use it to grasp the package, analysis protocol or monitoring network, is a better tool, because recently in the study of this, so write a tutorial to facilitate everyone to learn.
