Wireshark provides insight into a computer network, which is useful when implementing protocols, debugging network applications, testing networks, and debugging live networks. Being able to see and analyze network traffic is very instructive. This chapter discusses the main components of the Wireshark ...
当不使用 -s 参数时,默认的包长(ICMP payload)是 56 字节。 MTUIn computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. 也就是说,MTU 是 Maximum Transmission Unit(最大传输单...

与很多其他网络工具一样,Wireshark也使用pcap network library来进行封包捕捉。视窗数据包捕获(WinPcap的) :WinPcap的是Windows版本的libpcap库,它包括一个驱动程序以支持捕获数据包。Wireshark的使用这个库来捕获Windows Live网络上的数据. Wireshark的优势: - 安装方便。 - 简单易用的界面。 - 提供丰富的功能。
The network interfaces (i.e., the physical connections) that your computer has to the network will be shown in the Interface pull down menu at the top of the Capture Options window. In case your computer has more than one active network interface (e.g., if you have both a wireless ...
In the Wireshark labs you’ll be doing in this course, you’ll be running various network applications in different scenarios using your own computer (or you can borrow a friends; let me know if you don’t have access to a computer where you can install/run Wireshark). You’ll observe...
