实验性质
本实验为操作分析性实验。
实验目的
1. 掌握Wireshark软件的基本使用方法。
2. 掌握基本的网络协议分析方法。
3. 使用Wireshark抓包工具,分析IP数据报的格式。
4. 加深理解IP协议的原理及其工作过程。
实验环境
1. 硬件环境:PC机1台。
2. 网络环境:。
物理地址:00-E0-4C-00-16-78
Ip地址:
3. 软件环境:Windows操作系统和Wireshark软件。
实验学时
1. Capturing packets from an execution of traceroute
2. A look at the captured trace
What is the IP address of puter?
2. Within the IP packet header, what is the value in the upper layer protocol field?
3. How many bytes are in the IP header? How many bytes are in the payload of the
IP datagram? Explain how you determined the number of payload bytes.
4. Has this IP datagram been fragmented? Explain how you determined whether or
not the datagram has been fragmented.
Use the down arrow on your keyboard to move through the ICMP messages sent
by puter.
5. Which fields in the IP datagram always change from one datagram to the next
within this series of ICMP messages sent by puter?
6. Which fields stay constant? Which of the fields must stay constant? Which fields
must change? Why?
7. Describe the pattern you see in the values in the Identification field of the IP
Datagram
Next (with the packets still sorted by source address) find the series of ICMP TTLexceeded
replies sent to puter by the nearest (first hop) router.
