Great ~~ 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

How to Use wireshark to view ssl content and wireshark to view ssl 1. To view the ssl content, you need to obtain the server rsa key of the server. 2. Open wireshark and find the following path: Edit-> Preferences-> protocols-> SSL Then click RSA Keys List: Edit, Create a New RSA key on the New RSA editing interface Where IP address is the IP address of the serve

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

"File"--"Save" Toolbar: Click on the "7th button, the Black round corner box in figure 1-5 " Then the following window pops up,Figure 1-6 Supported packet storage formats for WiresharkThe new version of Wireshark supports many formats "black rounded box callout in figure 1-6 " when storing packets. As you can see, the default type of Save is pcapng, which may be a lot of advantages, but for compatibility reasons, I recommend that you set the

? How do we make the choice? Interface can be simply understood as the system for local communication with the outside world Bridge, the general system exists in the interface has Ethernet (network cable), Wi-Fi (WiFi) and other virtual interfaces. In the selection is can be used by the local WiFi or network cable to choose, if the first capture of the virtual machine traffic, you can also select the virtual network interface Main display window used to capture traffic: display f

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

is blue. 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.
