Wireshark is a Free and Open Source protocol analyzer used for troubleshooting networks, and analysis of communication protocols. The Lua programming language support has been included in Wireshark for scripting, prototyping and packet dissection. At Aerospike, a NoSQL database company, we have implemented a Wireshark Lua plugin to help us solve issues at the wire level. In this talk, I will be sharing the experiences and knowledge gained in creating a Lua dissector plugin. This includes project organization, code snippets, prototyping, testing, metrics and documentation. Real-world examples illustrating the plugin use for client-server communication, and intra-node cluster communication will also be demonstrated.
