IP on Ethernet

Abstract - The Lab Virtual Machines were used to create 4 pings that will transmit from the Windows machine to various networks, and analyze the packet data that was transmitted. The process will be performed using tightvnc and Wireshark.

Introduction – The study was performed using a monitor workstation to execute a ‘tcpdump’ and listen for incoming packets as they are transmitted from one machine on the network, to various networks. After the pings were created on the windows machine, the data was collected into a pcap container and analyzed with wireshark in order to discern the various bits of data that was transferred.

Materials and Methods

* School PC * Tight VNC * Wireshark * Lab Manual

* Use tightVNC to connect to cgs4285-a.cs.fiu.edu:5921-22-23 * On the linux machine, use the ‘ifconfig’ command to add the default gateway * On the Windows machine, go to the Connection settings and add the default gateway * In the Monitor, remove the default route * After removing the default route and set up the specified route in the manual * Run tcpdump on the monitor station to listen for traffic on both networks * Start ping 1 * Start ping 2 * Start ping 3 * Start ping 4 * After running all 4 pings, kill the tcpdump processes * Copy the two pcap files FIU account * Use Wireshark to analyze data

...Lab 1: Introduction Metric System Prefixes (to put in front of basic units): k = kilo = 1000 x c = centi = 1/100 of (which is 10-2 of) m = milli = 1/1000 of (which is 10-3 of) ( = micro = 1/1,000,000 of (which is 10-6 of) n = nano = 1/1,000,000,000 of (which is 10-9 of) (d = deci = 1/10 of ) [pic] (Note: The way to read the numbers above, for example, is: There are 1000 nm in one (m. There are 1000 (m in one mm.. etc.) To convert from one metric unit to a different metric unit (a different prefix): 1. First, decide how many places to move the decimal point (the number of 0’s in the chart above indicates the number of places to move the decimal point). 2. Next you need to decide whether to move the decimal point left or right. To decide this, think about which is the smaller unit. (The smaller the unit is, the more of them you need to get the same amount. e.g. pennies vs. dollars) NOTE: Here is another way to write the conversions, using distance (the meter is the basic unit for distance) as an example: 0.001 km = 1 m = 10 dm = 100 cm = 1000 mm = 1,000,000 (m = 1,000,000,000 nm The “staircase” method: One more way to remember about sliding decimal points when converting between prefixes in the metric system! [pic] Move the decimal point 3 places for every step you move on the “staircase”, and in the same direction traveled on the staircase (left vs. right). Unfortunately, you can see that the “c”......

...Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse, blood pressure, respirations, hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff and stethoscope using antibacterial wipes * Ensure the patient is comfortable and has been resting for 10 minutes * Remove tight clothing and support the arm at heart level, overestimation or underestimation can occur if it is not at the appropriate level * Ensure you have the correct cuff size for the patient or this could give an inaccurate reading * Locate the brachial artery and apply the cuff * Estimate the systolic pressure by using the radial pulse and inflate the cuff until the pulse cannot be felt. This is important to provide an estimation and avoids error in reading. * To take the patient’s blood pressure use a stethoscope and place on the brachial artery pulse and inflate 20-30 mmHg higher than the estimated systolic pulse * Immediately release the pressure using the thumb valve at approximately 2mmHg per second. If it is deflated too rapidly you may not hear the sounds accurately * The systolic pressure is the level when clear tapping......

The Freundlich Isotherm q=αC1v was then found to be a better model to approximate the adsorption isotherm for BSA as compared to Langmuir Isotherm. From the experimental data, the static capacity determined from Langmuir Isotherm approximation was estimated to be 330.033mg/g and the dynamic capacities flow rates of 5.0, 2.5, 0.5 ml/min were 0.918, 1.431 and 2.066 mg/g respectively, thus agreeing with theoretical knowledge that the static capacities should be larger than dynamic capacities as sufficient time were allowed for......

...Final Lab Report (Water Quality and Contamination) Student’s Name Course Name Institution Instructors Name Date of Submission Final Lab Report Abstract Establishing water quality was done by analyzing the chemical, physical and biological characteristics. This process helped determine safe water for human consumption in public in addition to making sure that humans are not affected by chemicals or disease causing organisms. This was done by analyzing 3 water samples which entailed Tap water, Fiji® bottled water and Dasani® bottled water. The goal of this research was to establish the effects of ground water contamination. This research necessitated hypothesizing on the capability of oil, vinegar and laundry detergent to pollute ground water in view of soil as a contributing filter of oil. Arising from the results obtained from the data analysis and observations from the experiments, conclusive evidence about bottled water was deduced and further research consideration is brought to light. Introduction Water quality was established by analyzing various characteristics which entail chemical, physical and biological. There are benchmarks of water quality set for every of these classes of characteristics. The benchmarks for water quality are advanced by (EPA) Environmental Protection Agency (2004) and (WHO) World Health Organization (2011). The quality of water taken in public was determined in the view of these benchmarks. Water quality research is significant due......

...Lab Report Introduction: Natural selection relies upon the assumption that all organisms produce more offspring than can survive in an environment demonstration limited resources. The heritable traits that are best suited for a particular environment should be passed on at a greater frequency then those less adaptive traits. Natural selection is unique in that it leads to adaptive change, and these changes are likely to lead to increased survival and reproductive success. To sum up, natural selection is that organisms can survive only because they can suit to the changed environment which means those organisms also need to change with the environment all the time. Hypothesis: during the experiment, the forks out of all the “predators” should survive, and the peas out of all those “preys” will be survived. Material and Metnods: We will use 4 kind of beans (preys items) which are fava beans, white beans, red beans and peas. And we also have 4 mouthparts (predators) which are knives, forks, spoons and foreceps. First, we get 100 ml for each prey and spread them on the ground. And the students will be divided into 4 groups with those 4 different predators. Each group of predators include 6 student. And all of the predators will have a cup which will serve as the stomach into which the prey will be placed. We also have a timer and a security that will make sure the process is fair. Here we begin the game. The predators will be gathered, they will be instructed not......

...Why do we keep a lab notebook? In the ‘real world’, you will be expected to record what you do and how you do it, with the data clearly identifiable. There are 2 reasons for this: • Any scientific experiment is only considered valid if it can be repeated by someone else using your notebook. • If you develop a new product or process, your notebook becomes a legal document that can be scrutinized in a court of law, especially in cases of patent infringement. In order to meet these requirements, certain conditions must be met: • Notebooks shall have bound pages, loose-leaf and spiral bound are not acceptable. • All pages must be numbered prior to use. This will show if any pages have been removed that contained data that might compromise interpretation of your conclusions. • All data shall be entered chronologically. Do not leave empty pages to insert information later. If you finish with a large expanse of blank page, put a line through it to show that it will not be used. • All notes are to be made in indelible pen – pencil will be penalized. If you make a mistake, just draw a single line through it, not a childish scribble to hide all traces! • All data will be recorded in your lab notebook at the moment it is generated. No notes shall be written on scraps of paper or memorized for later. Other notes about the lab notebook: All pre-lab and experimental work is hand-written in your lab notebook. ......
