Lab 8 – Subnetting

Objective 

In this lab, we built a working network with subnets using routers, switches, hubs and computers.

Equipment 

Router

Switch

Hub

Computer

Hyperterminal

Notes and Observations

We started this lab by first drawing out the intended network with everyone having a unique subnet given we were using a class b network and borrowing hosts as needed and began making connections. By connecting each computer to a switch and then a router, we followed this process to create our network. After this, we copied the hyperterminal folder to the desktop to have the ability to configure each router and its respective interface separately with the corresponding IP address.

Conclusion

Although the lab was very straightforward and simple, I ran into some problems between configuring the router and being able to successfully ping any otbher router and/or computer. Despite the failed attempt, more practice will be done to further successful networks in the future.

 

Lab 7- Packet Sniffing

CMST 250, Networking I

Objective 

In this lab, we discussed how a packet sniffing analyzer sees what is happening in a network. There are several variations of analyzers available for each operating system.

Equipment 

Internet connection

Computer

Downloaded version of  packet sniffing tool, in this case, Wireshark.

Notes and Observations

In this lab, we were instructed to download Wireshark and click the capture menu and then select start to begin capturing network traffic information. While the program is running, there are multiple ways to save and see the captured data. The easiest way to do this is by pinging the host to ensure connectivity. After each activity, make sure you click stop to receive new data for each activity.

Conclusion

In conclusion, I was able to successfully download Wireshark and able to ping my connection to ensure I was able to receive a return from my ping to see packets that were going through my connection,

Lab 6 – Network Simulation

Objective 

The purpose of this simulation is for students to walk through the process of data encapsulation – where the PDU for one layer becomes the data for the next layer.

Equipment 

Laminate paper and envelopes

Notes and Observations

In this lab, we made a small network connection with laminate papers and envelopes to enact the flow of a network and how encapsulation takes place and only there is communication among the respective layers. Layer two speaks to layer two, layer three to layer three and so on. The higher layer takes the message or information and puts it into a packet or frame that is sent and read and slowly gets to its destination until it reaches its respective complimentary layer after it goes through every possible layer.

Questions

N/A

Conclusion 

In this lab, I learned how information is sent through a network and encapsulates information until it reaches its respective destination due to each layers respective protocol.

Lab 4- Network Devices and OSI Model

Objective
Learn about the OSI model as a method of understanding modern computer networks.

Equipment
Workgroup Switch

Etherlink 3

Datasmart

ST-500

Modem

 

Notes and Observations
In this lab, we discussed the various network layers and their operation of each one along with examples of what they look like in their respective physical and digital states. By typing in cmd in the run screen, along with ipconfig/all, we were able to pull up the IP address and look up the  MAC address and where it was assigned. After finding this, used the ping command to receive a reply from Singapore. After receiving a response from Singapore, tried several other countries but with no luck. After running this, ran a tracert on the main campus webserver with responded in 30 hops.

Conclusions
In this lab I accomplished finding the IP address and MAC address on MAC or Windows based systems. Also leaned Please Do Not Throw Away Sausage Pizza to remember the order of the OSI model and their functions along with what they look like.

Lab 5- Webserver Lab

Objective

Use Raspberry Pi to create a webserver with a customized web page.

Build a local area network and share your web page with others in the lab to view via their Raspberry Pi.

Play a game of Minecraft with others in the lab.

Equipment
Raspberry Pi

HDMI Cable

Keyboard/mouse

Monitor/screen

Internet connection

Notes and Observations
In this lab, we were instructed on how to properly make our own Raspberry Pi setup, create a webpage, and connect into a LAN connection to play Minecraft. Thanks to google resources, we were able to setup a webpage and edit with commands to add words and pictures to create our own unique page. After a successful webpage, we created a connection to play minecraft and ensure our Raspberry Pi was able to handle a connection.

Conclusions
In this lab I accomplished setting up a Raspberry Pi and playing Minecraft for the first time. Also learned how to setup a webserver page and edit as needed with certain commands.

Lab 3 – Cabling

Objective
Learn about the tools necessary to create a straight-through patch cable, install RJ 45 connectors on an existing twisted-pair cable, then test the cable with a network cable tester

Equipment
RJ 45 CAT-5e Ethernet cable
Bulk Ethernet cable
Several RJ 45 2 piece Modular Plug Connectors
Modular Plugs
Klein Tools VDV501-825 VDV Scout Pro 2 LT Tester .
RJ 45 Network cable stripping tool

RJ 45 Network cable crimping tool
CAT 5 Punch down tool
CAT 5e panel
CAT 5e wall jack

Notes and Observations
In this lab, we were instructed on how to properly make our own patch cable and test it with a cable tester. After stripping the wires and correctly configuring them into a RJ-45 connector, then proceeded to test the connection. The first test around failed with two ports being read as open. It was saying that there was not a full connection between two of the connectors which led to re stripping and connecting the wires better by pushing them all the way through connector and re crimped them to a test to pass. After this, the creation of patch panel began. It was important not to untwist the cables because it keeps the connection stronger by leaving them together. After another test with cable and the newly designed patch panel, a successful connection and working cable was made.

What Is Thicknet and Thinnet? (n.d.). Retrieved from https://www.techwalla.com/articles/what-is-thicknet-and-thinnet

Questions
What are some advantages and disadvantages of Thinnet and\or Thicknet compared to UTP? What are advantages of using fiber optic cables?

Conclusions
In this lab I accomplished making a network cable by putting modular plugs on the end, connecting a networkcable to a patch panel, and a wall jack, and testing the cable with a network cable tester to verify that the cable works. The lab was successful. I learned about different ethernet cables including Thick Ethernet (Thicknet), Thin
Ethernet (Thinnet), vampire taps, multi-mode fiber optics, and different wiring standards. Thicknet is more expensive than Thinnet and harder to work with.. Thinnet is mainly used in homes whereas Thicknet was used in bigger businesses but despite this, if there was a break in the cable, the entire system stops. Some advantages of fiber optic cables are it is more flexible than the others along with it being able to send data at a much faster rate than its predecessors. Some disadvantages are how expensive it is to install almost anywhere and it is difficult to splice.
