You can use it to solve network problems, network protocol analysis, and as a software or communication protocol development reference, but also can be used as learning various network protocols teaching tools and so on. Wireshark Support now has the majority of Ethernet network cards,

Preface:Recently, to build the strongswan environment, Wireshark is required to capture packets. One computer is always unable to access the network (only through the LAN), and cannot directly apt-get. So I studied the following software installation methods, especially in Ubuntu, how can I directly copy and install the installation package like in windows. This article is available.
