The first experiment: using Packet Tracer analyzes HTTP packets
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
Given a network topology is as follows: Select the first terminal device (End Devices) and the Server PC and link
(2) Configuration Parameters
pc and open the desktop, set the IP address (192.168.1.17) client
Similarly: Click Serve, select the desktop to
(3) capture and analyze packets captured
Set Packet Type:
Ethereal carried out:
http request message:
HTTP Data: Accept-Language: en-us express http request
Accept: * / * acceptance data type is arbitrary
http response:
HTTP Data: Connection: close state indicates that the connection is closed
Content-Length: 369 indicates the length of a transmission entity 369
Content-Type: text / html coding type represents the information to the server when the html
Server: PT-Server / 5.2 type information indicates that the server
(4) by generating new questions and answers about the experiment
If the pc-a and IP addresses serve the same time, be able to capture
Answer: No
b value when the coding type information server can be changed
