P = 1293 use tcpdump/Wireshark to analyze the existing live broadcast technology on the Android platform To resolve the live video protocol on Android phones, you can capture packets to view existing live video applications, such as Phoenix TV and mobile TV. The main methods are as follows: 1. Install the live video
Wireshark is an essential artifact of network programming 1. Filter IP, such as source IP or destination IP equals an IP example:IP.SRC eq 192.168.1.107 or IP.DST eq 192.168.1.107OrIP.ADDR eq 192.168.1.107//can display source IP and destination IP2. Filter portExample:Tcp.port EQ 80//Whether the port is source or target is displayedTcp.port = = 80Tcp.port eq 2722Tcp.port eq or udp.port eq 80Tcp.dstport = = 80//target port 80 for TCP protocol onlyTcp.s

Wireshark can get HTTP, can also get HTTPS,But can not decrypt HTTPS, so Wireshark can not understand the contents of HTTPS.S

The host name can be a local host or any computer on the network. The following command reads all data sent by the host hostname: Tcpdump-I eth0 src hosthostnameG. the following command can monitor all data packets sent to the host hostname: Tcpdump-I eth0 dst host hostname # src indicates the source, that is
Wireshark is a very useful packet capture tool. When we encounter network-related problems, we can use this tool for analysis. However, it should be noted that this is just a tool, the usage is very flexible, so the content described today may not help you solve the problem directly, but as long as you have the idea of solving the problem, learning to use this software is very useful.Wireshark http://www.wireshark.org/download.html officialIf you cann

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 Wireshar
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. First of all, Wireshark's start and grab interfaces Start interface: The start of the scratch-wrap interface is Press the button under File And then there will be This is the display of the network
). TCP provides high reliability data communication for two hosts. His work involves dividing the data that the application gives to it into appropriate chunks to the network layer below, confirming the packets received, setting the timeout clock for sending the last confirmed packet, and so on. Because the transport layer provides high reliability end-to-end communication, the application layer can ignore all of these details. UDP, on the other hand,

send the command, the niosii still enters the interrupted service function and receives empty commands or unknown redundant commands. Why is the PC automatically sending commands? The PC here is not C #. (2) The PC-side command can only enter the interrupt service function of the niosii at most once, while the PC-side command waits for the PC command and the PC-side Command sends the command. The essence of this problem is that the PC and dm9000a send data to each other. The dm9000a receive
1, WireSharkWireshark is an open source free high Performance network protocol analysis software, its predecessor is very well-known network analysis software Ethereal. You can use it to solve network problems, network protocol analysis, and as a software or communication protocol development reference, but also can be used as learning various network protocols teaching tools and so on. Wireshark Support now has the majority of Ethernet network cards,
