Networking Lab 7

Objectives: To build a network and include subnets within it. To configure the router(s) so all of the terminals can be connected and utilize the subnets.

Equipment list: Routers(3), crossover cable, cat5 cables, computers, downloaded a hyperterminal to configure the routers

 Notes and Observations: This proved to be a difficult lab in terms of getting the physical components set up. Getting the network and subnets set up was easy on paper. The topology never quite took shape because we spent so much lab time fighting with hardware. This lab would have been easier if we had more working computers and were only configuring 1 router. We had 3 and it ended up causing problems. We followed the lab as far as we were able in the time we had.

 Diagrams, flowcharts, and figures: Incomplete diagram. Charted our topology as far as we were able to get.

 Questions: How many subnets are needed? We determined we would try to use 3 routers and configure 5 subnets all together.

 Conclusions: This lab was a lot easier on paper. Setting up the paper part of the network and getting the addressing set was very simple. Getting the routers to converse with the computer became a little more complicated. All in all, I would say we got this lab near finished until the hiccups at the end. I understand how to create subnetworks. I just don’t know how to configure a router.

Networking Lab 6

Objectives: To use Apache to set up web servers and connect with other computers in the classroom and to alter the document root so the homepage for the server can be different from the default.

Equipment list: Computer, apache software

Notes and Observations: Downloaded Apache and installed. Used localhost to see the homepage after setting up the web server, was able to connect to another classmate’s server and see their homepage. Found this lab easier than expected, but the instructions for this one made more sense to me than other labs have. I was able to get everything to work as described.

 References: Wikipedia, Apache website FAQ

Questions: How many languages does Apache support? I looked in the website’s FAQ and documentation section but didn’t find the answer. Turns out the languages were listed in the documentroot file.

Conclusions: I learned a lot more about configuring different settings on the computer. I was really happy that I was successful in following along with this lab and getting all of the objectives completed. I don’t think I will be using this at home, but it was good to learn about something completely new.

Networking Lab 5

Objectives: To capture packets using Wireshark and observe the different types of information the program presents depending on the activity being done while capturing.
 
Equipment list: laptop, wireshark program
 
Notes and Observations: This was hard to understand at first. It was interesting to see that TCP had sequence numbers and UTP didn’t. I began to see how TCP organizes information and UTP disregards order. I also saw how many different web sites were involved in one simple navigation online.

Conclusions:

Successfully used wireshark and learned a lot in the process. Especially about TCP and UTP!

Networking Blog 5

This week I learned about a program called Wireshark. It captures internet packet activity and provides information about what is sent and received while it is operating. There are different pieces of information provided depending on what activity you are doing. I looked at information sent and received when viewing/accessing a web page. The middle pane provided source and destination information including IP addresses. As to the other experiments using Wireshark, I didn’t do them yet because I don’t understand what the lab is asking me to do. I will do further research to understand what is being asked before I attempt to capture more data on Wireshark. None of the information really makes sense to me yet. I did search to see if I could find a classmate’s blog, but I was unable to locate any.

Networking Lab 4

Objectives: To configure a network of several computers using a switch, change the IP address of my workstation, and then to ping neighboring computers. Also, a goal was to configure a router.

 Equipment list: Switch, several workstations, router, UTP cables

 Notes and Observations: My group followed the lab and went through changing our IP addresses and connecting to each other through UTP cables into a switch. We had issues with this lab because there were few operational workstations. We were also unable to connect to one member’s laptop because of firewall issues. I was able to ping the K-State server, which returned Spiderman as its name. We were unable to configure a router to connect to other groups in the class. This lab didn’t work well because of all the equipment problems we had.

 Questions: Compare and contrast the IANA and ARIN? I know that these two organizations are responsible for the distribution and assignment of IP addresses, but I don’t really understand how they are different.  There is a countdown happening because IPv4 address are depleting. IPv4 addresses are still being assigned as they are available on a first come, first served basis.

 What are some reasons behind updating the TCP/IP protocol with a new IPv6 standard? IPv6 uses 128-bit addressing so it will be a long time before address assignments become exhausted. Because IPv4 addresses are almost used up, they had to develop a new system for addressing due to the number of internet devices in use.

Conclusions: I was able to ping K-State but not another computer because of the technical issues we were having. The computer lab isn’t set up well for what we were trying to accomplish this lab. I was shown how to use a terminal to set up a router, but I wouldn’t be able to replicate this process on my own. It was interesting to learn about configuring IP addresses, but I don’t think I will end up doing this on my own. I think the computer lab isn’t very well organized, but I don’t think it is the instructor’s fault that half the computers weren’t working. I suppose more people should have their laptops in class so these types of projects work better.

 

Lab 3

If we already had the TCP/IP model, why was the more complicated OSI model created?
It allows for the development of communication layers with each layer providing its own specialized function within the structure. It became a way to standardize the rules of networking.

http://wiki.answers.com/Q/What_is_the_main_reason_the_OSI_model_was_created

What does the abbreviation OSI stand for? Who originated it? When?
Open Systems Interconnection. Originated by the International Organization for Standardization based on the work of Charles Bachman. Developed in the early 1980s.

http://en.wikipedia.org/wiki/OSI_model

Determine the highest layer of operation for the following network devices: switch, hub, NIC, router, cable media, wireless access point. patch panel, repeater, bridge. Hubs, repeaters and cable media are on the physical layer. NICs, switches, patch panels and bridges and are on the data link layer. A wireless access point and router are on the network layer.

What is another name for a physical address? How many bits do they require? When two machines attempt to transmit simultaneously on the same media segment, both messages become garbled and unintelligible. What is this condition normally called? The IP address is the physical address of a network device. It requires 32 bits in an IPv4 address. When two machines attempt to transmit on the same media segment and the messages get messed up, it’s called a collision.

http://en.wikipedia.org/wiki/IP_address

What is your IP address? What is your MAC address?
My IP address is 192.168.1.10. I can’t find my MAC address in the ipconfig window.

ARP  ends in a “P” so what does that often signify? What does ARP stand for & what does it do? Why is ping useful? What address is added to the arp table when you ping http://www.sal.ksu.edu? Why? ARP ends in P and most of the acronyms in networking stand for ‘protocol.’ ARP stands for address resolution protocol. The stackoverflow website states, “It’s a mapping mechanism for going between IP addresses and MAC addresses, on local networks. For connecting to a specific host a long distance away it’ll just be used for finding the MAC address of your default gateway (or routers more generally).”  Ping is a network debugging tool. When I ping http://www.sal.ksu.edu I get back spiderman.ksu.edu because that is what the IT guys named it.

http://stackoverflow.com/questions/7301318/what-does-arp-do

If a packet comes in from another network, only a layer 3 (IP) address is known. But direct machine to machine communication only occurs at layer 2. What method is used to translate a known layer 3 address into an unknown layer 2 address? ARP translates a layer 3 address to a layer 2 address.

http://en.wikipedia.org/wiki/Address_Resolution_Protocol

What are layer 3 gateway devices called? They use logical, or software encoded addresses. Many types of software addresses have been developed and used. What is the de-facto standard for logical addresses used today? How many bits do they require? Layer 3 gateway devices are called routers. Routers require 8 bits I think.
