Disorderly Sequence Message : The serial number of the current message is lower than the previously received message from the connection
previous fragment failed to capture : (Wireshark 1.8.x and above): Lost with previous message.

To make a long story short, Wireshark has a follow TCP stream feature, which is handy. The drawback is that the extracted stream data does not have time stamps and other information, in the analysis of data delay and packet loss is somewhat inadequate. In this case, a simple follow TCP stream function is implemented with Python, while the TCP information is preserved.The principle is simple and is still based on W
). 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, provides a very simple service for the appli

Wireshark-Network packet analysis software
The function of the network packet analysis software is to retrieve the network packet and display the most detailed network packet information as far as possible. Wireshark uses WinPcap as an interface to exchange data messages directly with the network card.
Network administrator uses Wireshark to detect
1. Open the Wireshark software and select the appropriate network card from the interface list, for example, "Local Area Connection" on my PC, then select "Start" to start the capture program.2. Open the School homepage, enter your account and password to log in to your on-campus mailbox.3. Terminate the packet capture program.4. In the Filter column filter fill
Due to the need to debug the differences between the pc Server printing film and the direct printing film on the device, R D requires me to capture packets to analyze the differences between the two, but soon faced a problem, I didn't have the permission to change the vswitch, and they didn't configure the port image on the vswitch. So I had to find a small HUB and eliminate the HUB for more than 10 years, this almost forgotten network device is a shared network that may easily cause network ac

By default, the root permission is required to access the network port, while Wireshark only requires a UI of/usr/share/dumpcap, and/usr/share/dumpcap requires the root permission, therefore, non-root users cannot read the NIC list.
The solution is simple. sudo Wireshark
However, Wireshark does not officially recommend this:

Wireshark, formerly known as ethereal, is an amazing network monitoring tool. It helps you to capture the data packets being sent/received by your network interface and analyze it.
