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
Basic IO Graphs:IO graphs is a very useful tool. The basic Wireshark IO graph shows the overall traffic situation in the capture file, usually in units per second (number of messages or bytes). The default x-axis time interval is 1 seconds, and the y-axis is the number of messages per time interval. If you want to see the number of bits per second or byte, click "Unit" and select what you want to see in the "Y Axis" drop-down list. This is a basic app

The window is similar, which is very helpful for reading protocol payload, such as HTTP, SMTP, and FTP.
Change to the hexadecimal dump mode to view the hexadecimal code of the load, as shown in:
Close the pop-up window. Wireshark only displays the selected TCP packet stream. Now we can easily identify three handshakes.
Note: Wireshark automatically creates a display filter for this TCP session.

What are legacy systems (Legacy system)? According to Wikipedia, legacy systems are an old method, an old technology, an old computer system, or an application [1]. This definition does not, in fact, reveal the nature of the legacy system. I think the legacy system is first
Because the computer pre-installed with the Win8 system has secure boot, the system cannot be directly installed through the EFI shell boot, and even if secure is disabledBoot and EFI only support 64-bit systems and must be partitioned using GPT. This is tough for users with hard disks smaller than 2 TB or no more than 4 primary partitions, so we should use legacy + MBR (legacy is the BIOS we were familiar
