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

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

SSL is a security protocol that provides privacy and integrity between communication applications that use TCP/IP. The Hypertext Transfer Protocol (HTTP) of the Internet uses SSL for secure communication.The data that is transferred between the client and the server is encrypted by using a symmetric algorithm such as DES or RC4. The public key algorithm (usually RSA) is used to obtain encryption key exchang
