Objective: The objective of this lab is to implement a network where a server, a router and some PC will be connected together. After building a network a ftp server and a http server will also be created and also implement a cloud networking system and to implement a wireless network for some PCs.

Procedure (step by step):

After opening the Packet Tracer we took one server, a router and a PC to create the network.

After that all the devices were connected with copper straight-through wires. Then the PCs were configured with the IP address and Subnet mask.

After that server was configured with the IP address and Subnet mask.

Then to check if the connection of the server, command prompt window under desktop in FMA was opened and ‘ping 192.168.1.254’ command was given to test the connection.Same for other PC’s.

For testing from PC to Server

Comments :

After that the configuration of HTTP under server was turned on and a message was written to it.

Then FTP server connection was configured with a username and password including read and write permission.

Fig-14 : Difference between Bridge and Switch

Comments : Hubs are commonly used to connect segments of aLAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.Unlike the Hab Bridge would only have two ports.one in and one out.

After that a wireless device was added to the server and a Link Sys wireless router and two laptops were added to the network.

Then the router was configured by disabling the authentication and by setting DHCP IP configuration.

The router LAN was configured then by setting the IP to 192.168.0.1 and the wireless authentication was disabled.

After that the HTTPconfigurationof the server was done by changing the message and site name by superyahoo.com instead of Cisco Packet Tracer.

At last HTTP connection was checked by opening a virtual web browser in laptop0 to check if superyahoo.com address can be browsed from laptop.

Discussion:

The connection of the network was built by a server, a switch and a single PC in the lab. It is not so important how much PC is connected to the switch but the important thing is to observe if the connection is working properly.All the connection are right and we get correct reply from the server.

After that we connected the network was built by a server, a switch a router, some PCs and laptops in the Packet Tracer..In this lab a wireless device was needed to add both in the laptops and server end then the devices were configured. So it is important to check the wireless connection first.Finally we check the connection by sending packets and browsing the web.

Conclusion:

The lab was all about wireless connection implementation in packet tracer. The wireless connection implementation was much easier than wired connection because the IP and subnet addresses were given by DHCP. In this experiment, we have implemented cloud networking system.
