Wireshark software introduction
By capturing all network packages and displaying the information of the packet in detail, it provides users with functions such as failure to eliminate, protect, analyze, and maintain. Wireshark has a powerful filter engine. Users can use filters to screen out useful data packets, eliminate interference of unrelated information, and quality assurance engineers use it to verify network applications.
Wireshark software characteristics
Wireshark software contains the ability of strong display filter language (Rich Display Filter Language) and the ability to view TCP session.
Wireshark also supports hundreds of protocols and media types;
A command line name of TCPDUMP (a network protocol analysis tool under a Linux);
In the past, network packet analysis software was very expensive, or it belongs to the software used by camp;
The emergence of Ethereal changed all this;
In GNU At the scope of the GPL general -purpose license, users can obtain the software and its schedule at a free price, and have the right to modify and customize its original code. Ethereal is one of the most widely used network packet analysis software in the world.
Wireshark software function
Support protocol
Wireshark is outstanding in terms of the number of support protocols, and currently provides more than thousands of support support.
User friendship
Wireshark's interface is one of the easiest tools in the dataset sniffing tool. Based on GUI and provides a clear menu bar and a concise layout.
free
Because Wireshark is open source, it is uncomfortable in terms of price. Wireshark is a free software published by the GPL protocol. Wireshark.
Procedure support
The Wireshark webpage gives many related links supported by programs, including online documents, support and development of Wiki, FAQ, and can register the email list that Wireshark developers are concerned about.
Support operating system
Wireshark provides support for mainstream operating systems, including Windows, Mac OSX, and Linux -based systems.
Wireshark common problem
What should I do if the packet analysis error is wrong?
1. Check whether the data package is complete and non -damaged. Try to update Wireshark to the latest version to obtain the latest protocol parser support. If the problem still exists, you can contact Wireshark's developers or visit related forums for help.
2. When capturing a large amount of data packets, Wireshark may have a decline in performance, such as the interface kattopon, slow response, etc.
3. Optimize the settings of Wireshark, such as reducing the number of captured data packets, reducing capture speed, closing unnecessary display options, etc. At the same time, you can consider upgrading computer hardware or using more efficient hardware capture equipment to improve performance.
Wireshark update log
1: The new interface, refreshing, simple, efficient
2: The performance is getting better and better
