1 Purpose
Familiar with Packet Tracer tool. Analysis caught HTTP packets, in-depth understanding: HTTP protocol, including syntax, semantics, timing.
2 Experimental content
The client sends a request message to the server, the server sends a response message to the client. Specific include:
- Establish a network topology
- Configuration parameters
- Ethereal
- Analysis of the data packet
3. The test report
(1) establish a network topology
Description: Connect with a host PC and a server, networking topology
(2) Configuration Parameters
IP address (192.168.1.64) client
Server's IP address (192.168.1.65)
(3) capture and analyze packets captured
1) Ethereal results
PC0:
server0：
2) packet capture analysis results
Request packet:
HTTP Data:
Accept-Language: en-us // represents the user wants to get the English version of the document priority
Accept: * / * // agreed to accept any data type
Connection: close // tells the server frees the link after sending a document request
Host: start 192.168.1.64 // header row. Given domain host
Response message:
HTTP Data:
Connection: close // After telling the server to send the requested document could link the release of
Content-Length: 369 // transport length of the HTTP entity as 369
Content-Type: text / HTML // data type of text or HTML
Server: PT- type server / 5.2 // server
(4) by generating new questions and answers about the experiment
Question: Host can access the server via the connection server, that you want to access another host how to do?
Solution: Use the switch to connect two PC, and configure the port;
Question: What message is?
ANSWER: The combination of Wireshark packet capture in-depth understanding of the HTTP protocol stack TCP / IP protocol , HTTP packets Detailed makes me a clearer understanding of the meaning of the message;
