For example, the interaction protocols between game client and server are usually private. But in practical application, these protocols are usually only the carriers of our data transmission process, and many communication protocols between software are private. Because of open source, it is easy for users to develop again, which makes the sword's appearance and function almost perfect.įor the current mainstream protocols, there are self-contained parsing plug-ins, such as IP, ARP, TCP, UDP, HTTP, DHCP and so on. Although it has a long history, its sharpness has not been reduced at all. I hear Michel Fagan speaking.… twitter.WireShark is undoubtedly relying on the Sword of Heaven in the arsenal of ICT personnel for network analysis.

Say you have a packet capture with a TCP connection. And the same night, I developed the first version. While answering the question, I realized that this is a case that could be solved with a generic dissector. When the data exchanged over TCP, for example, has the CSV format (fields separated by a separator), how can I write a dissector for that? During the second day, when we cover the development of custom dissectors written in Lua, a question about CSV data came up. In December 2020 I provided online Wireshark training to one of our NVISO clients.

Wireshark use protocol lua
