Recently, I promised to help people solve a problem, that is, to analyze an online video. It is a client player, but some audio sniffing devices cannot sniff the address. So I found a bunch of network packet capture and listening tools on the Internet. However, these tools made people feel very uneasy and did not dare to experiment with their own computers. So I started the VPC and used the VPC for the experiment.
I have never used the VPC network function. Today, it is quite simple to use. In the network settings, select the NAT mode. After the instance is started, the Intranet address 192 will be automatically allocated. 168 ..., without DNS, you can directly connect to the Internet with DNS configuration. All network functions are available.
The data packet analysis process is very simple, and the next software is used only for the first one. The basic process is to start listening, start playing, analyze data packets, first access port 80, and then find the first request of port 10079, and then find the address.
