SNIFFING!

April 22, 2011

EQUIPMENT:

Computer, Wireshark

NOTES/OBSERVATIONS:

This lab is intended to teach us how to be hackers.   …ok, that’s probably not the intention of it.  However, since we did use a program that monitors network packets, it could very easily be used as such.

DIAGRAMS/FIGURES:

N/A

REFERENCES:

Lab Notes, Google, and Kristin (since I was gone on lab day)

QUESTIONS:

*Find the frame’s protocol type, lenth, source & destination address information.

- TCP, 56 bytes, AsustekC_65:f4:24

*What do you notice about these frames? What can you say about the security of the FTP protocol after viewing these frames?

-Since I can read my username and password within the frame, I’d say the security could improve.

*What protocols are encapsulated in this frame? Which of these protocols is a transport layer protocol?

-IP, DNS, and UDP  (transport layer)

*What protocols are encapsulated in this frame? Which layer does ICMP reside in?

-IP and ICM, ICMP=layer 3  Internet Control Message Protocol

*Approximately how many frames did it take to download the web page?

-870

*What protocol headers do you see?

-IP, TCP, HTTP

*Find the type of web server being accessed in this frame’s header.

-Apache

*Find a pair of frames that show an ARP request and an ARP response. Explain what these frames are doing.

-looking for an IP

CONCLUSION:

Even though I wasn’t able to be in the lab, doing this in my spare time helped me to understand how hackers perform their hacking.    It’s kind of scary to think that it is relatively easy to get ahold of valuable information if you don’t take the necessary precautions to protect yourself.

Subnetting

April 18, 2011

OBJECTIVES:

To be able to construct a network using subnets.

EQUIPMENT:

Computer, Routers, Switches, Knowledge

NOTES/OBSERVATIONS:

We worked together as a class to complete this lab.  First, we drew our network on the whiteboard, assigning IPs to our various computers, visually explaining the process for setting up our network.  We had 3 routers that had to be configured.  We also had to manually configure our computer’s IP addresses.  This took more time than we had planned… but eventually we figured it out.

QUESTIONS:

CONCLUSION:

This lab took some time, but eventually ended up successful.  All three of our routers were configured correctly so that we could ping each others computers in different subnets.  While subnetting isn’t my forte… I was able to follow along and learn more about the procedure in using subnetting.

This was a short week for me, as I wasn’t in class on Monday, and no Lab on Friday.  Last week’s lab and discussion has mostly been over subnets… a complicated mumbo jumob of 1s, 0s, and binary conversion.  It’s taken me awhile to actually catch on, but I think Wednesday’s exercise made it all stick in my brain.  Some terms we’ve discussed and expanded upon recently include: subnet masks, bits, gateways, and IP addresses… and how they all work together.

My contribution was most significant during the Lab, as we had to set up our own network.  I pretty much told my partner what to do, and we rocked it… except for the 10 minutes we wasted trying to figure out why the router wouldn’t work.  (Note:  Make sure you flip the switch to “ON”. )

March 18, 2011

OBJECTIVES:

To become familiar with, and to create our own FTP web server.

 

EQUIPMENT:

Computer, Internet

 

NOTES/OBSERVATIONS:

I really had no idea what we were doing in this lab, but I had a great lab partner who was patient with me.  We had to do quite a bit of research for this lab, and were asked lots of questions that were supposed to help us better understand what we were doing.  ;)

QUESTIONS:

What is the most popular type of web server in operation?

Apache

Has this always been the case?

No, it used to be NCSA.

Describe the growth and evolution of web servers over the past ten years.

Apache basically started the charade, and now google basically rules the world.  :)

Explain how the number of registered names has grown and how the web server software
preferences have evolved.

About 12 million web server names have been added, and apache is pretty popular because it’s free.

What is the main configuration file for the Apache server?

httpd.conf

Are there other configuration files? If so, what are they for?

Yep.  Character sets and mime files.

What is the path to your document root directory?

C:/ProgramFiles/ApacheSoftwareFoundation/Apache2.2

How many languages does Apache support pre-installed?

Ocho  (That’s 8 in Spanish.)

What language did you choose to change to?

Espanol.  (That’s Spanish for Spanish.)

What are some other hardware/software platforms besides Intel/Windows machines that are supported by Apache?

Intel/Apple, Intel/Linux

Would you recommend Apache as a good server for a commerical application? why or why not?

Sure, its free!

What cost would be involved with operating Apache?

If you understood what you were doing, there would be virtually no cost.

What is the default address it wants to connect to?

127.0.0.0

Is this the address of your FTP server?

Nope

If someone on another host wants to connect to your FTP server, what address should they use?

My IP address.

What port does the FTP server run on?

20 and 21

What port does the Web server run on?

80

What http address should you enter to view the aboutme.html file on your web server?

http://73.10.7.21/aboutme.html after moving it into the htdocs folder

What does the ls command do?

It shows the files in the directory.

What are some other servers that can operate on the internet?

Mail servers

 

CONCLUSION:

Honestly, I’d have to do this lab several times before I really understood what it is that I accomplished.  However, it was good exposure to web servers, and at least I can claim that I set one up!!

TCP/IP Networks

March 5, 2011

OBJECTIVES:

To become more familiar with networks, including the proper steps to take when setting up your own personal network.

 

EQUIPMENT:

Ethernet cables, PCs, router, switches.

 

NOTES/OBSERVATIONS:

We actually configured our own networks, one side of the room being “Network B” and the other “Network A”.   We first had to manually configure our IP addresses, and then hook our computers together using a switch and router.  In order to link the two networks together, we used Hyperterminal to configure the router.

REFERENCES:

http://www.iana.org , http://www.arin.net

 

QUESTIONS:

Compare/contrast IANA/ARIN.

IANA deals with root assignments and protocols.  ARIN gets its IP assigned to it by the IANA in a certain region.

What are some reasons behind updating the TCP/IP protocol with a new IPv6 standard?

IPv6 came about mainly because they ran out of addresses in IPv4.

What are some reasons to continue ues of IPv4?

Not all devices can run IPv6, so IPv4 is still important to keep around.

What is the highest OSI layer the computers are communicating with in the lab network.

Layer 3

How did you test your connection with other computers on the network?

I communicated with other computers on the device by using the ping command, which drew back a response.

 

CONCLUSION:

Since I’m still learning about networks, this lab helped me to understand the processes required in order to configure our own network using switches and routers.

This week we learned mostly about switches, and partook in a legit simulation that included sending messages to our switch (Wait a minute, now…  ).  We learned rather quickly if they had what it takes to get the message to the right place.  (Under Pressure!)    We also discussed enscapsulation, and the steps the different layers have to undergo before they can travel to their destination.  The simulations are definitely helpful, mainly because when the class gets off onto some oddball side-topic, I have no idea what the deuce they’re saying, so I become easily distracted and focused on my cellular device.  I do, however, learn more about SOCIAL networks during this time. 

Besides being an awesome student, I contributed to my team this week by being the “OUI”, or Wii game console.  I rocked it.  Hopefully next week I’ll challenge the “LFINO” network to a Wii Tournament, eh?  Prepare for domination.

t-storm in the hizz-ouse.

I’m quickly learning that in order to get more views on your YouTube channel, you have to be a frequent uploader.  This means at LEAST weekly videos to keep people interested… especially if you’re crazy weird like I am, you have to keep convincing people you’re stuff is worth watching.   Either that, or keep them guessing… “Is this chick for real?!”    Yaddah, yaddah.

My most recent videos have been quite different that my first ones… as far as time spent filming and editing.  In the beginning, I was spending upwards of 8 hours on just ONE video that MIGHT end up being 3 minutes long.  (And that’s pushing it.)  So after much YouTube surfing… I’ve decided that some of the videos that get the most views are the ones that don’t have many cool effects inbetween clips.  People like to watch both ends of the extreme… that is:  Really fancy, flawless editing…. professional looking, you know.  OR they like minute long clips people take from their cell phones, and upload without editing a single thing.

Because I’m trying to become a superstar… my approach has started to become the latter end of the extreme.  While I DO still do some editing… I only spend like an hour or two on each video.

One of the more recent vloggers I’ve found calls herself “JennaMarlbles”…  and her style is basically what I’ve been doing.  (Note:  I totally was making MY videos before I heard of this chick, so if you threaten me with copyright infringement, I might just punch you in your esophagus.)

While her sit-in-front-of-the-camera-and-talk style is basically what I do… I do NOT appreciate the topics she chooses to elaborate on, or the foul language she uses to portray her ideas.  If YouTube wants some vulgar, inappropriate videos… I’ll find another gig.

OSI LAYERS

 

OBJECTIVES:

The main objection of this lab is to become more familiar with the OSI Model.

 

EQUIPMENT:

Internet, pencil, paper.

 

NOTES/OBSERVATIONS:

This lab mostly asked questions that required research via the Internet.

 

DIAGRAMS/FIGURES:

Chart from Lab, Question 3

 

REFERENCES:

tcpipguide.com, wikipedia.com, Mr. Bill Genereux

 

QUESTIONS:

1.  If we already had the TCP/IP model, why was the more complicated OSI model created?

It was intended to serve as the foundation for the establishment of a widely adopted suite of protocols that would be used by international internetworks – basically the Internet.

2.  What does the abbreviation OSI stand for? Who originated it? When?

Open Systems Interconnection: Charles Bachman, 1984

3.  Determine the highest layer of operation for the following network devices:

switch (2), hub(1), NIC(2), router(3), cable media(1), wireless access point(1), patch panel(1), repeater(1), bridge(2)

4.  What is another name for a physical address? How many bits do they require? What is the condition of two machines attempting to transmit simultaneously on the same media segment normally called?

MAC address, 48 bits, collision

5.  What method is used to translate a known layer 3 address into an unknown layer 2 address?

ARP (address resolution protocol): coverts IP to MAC

6.  What is your neighbor’s physical address? What address is added to the arp table when you ping www.sal.ksu.edu? Why?

00-0e-a6-7f-37-29, no address comes up with the website because it’s within the K-State network

7.  What are layer 3 gateway devices called?What is the de-facto standard for logical addresses used today? How many bits do they require?

router, IP=32 bits

8. You can get more information about connectivity by running a trace route. What kind of information does this utility provide? Describe the path a ping packet must follow to get from K-State Salina to Kansas Wesleyan?

Trace routes provide IP address of different stops between the sender to the destination.  The ping packet starts at KSUS, goes to Chicago, Texas, Dallas, and the KWU.  Took around 40 milliseconds.

9.  What information is provided in the switch MAC address table?

Vlan, MAC address, Type, and Port

 

CONCLUSIONS:

I found the research required to answer the questions in this lab helpful in better understanding the OSI model.  The hands on approach is definitely a great way to learn, especially when we traced the ping packets.
