Computer Networking Technology - Essay Example

A This LAB requires a workstation running Windows or UNIX that has the TCP/IP protocol installed. Ideally, the workstation would be connected to a LANA that allows Internet access. In this project, you will view and modify a client’s TCP/IP properties using the upcoming command. 1 . Click the Windows icon and on the “Search” box that immediately follows, type COM 2. Your command prompt will likely appear as a letter C followed by a colon and then the name of the directory in which you’re currently working. For instance, you might e a prompt that reads “C:Documents and SettingsClauses 1>. “) Type upcoming and press Enter to view a summary of your workstation’s TCP/IP properties. 3. On a separate sheet of paper, write down the values of the four items displayed in the output (or paste them here). Upcoming 4. Next, you’ll issue the same command, but add the all switch to obtain the complete TCP/IP configuration for your workstation. Type upcoming all and then press Enter. 5. Read through the output of the upcoming all command.

If you are connected to a network that uses DDCD, notice the date and time when your lease was obtained and hen it is due to expire. On your paper, write down your machine’s host name and also the MAC address for your workstation’s NICE. (or paste them here). (or paste them here). 6. Next, type upcoming [release and press Enter. What message is displayed? What implications do you predict this command will have on connectivity? There’s no connectivity. 7. Using your screen shot as a reference, attempt to ping the DDCD server and the DNS server. What are the results? 8.

Type Upcoming and press Enter. Note that your adapter has no IP address and no subnet mask. These two parameters are necessary to communicate with TCP/IP. 9. To get an IP address lease again, type upcoming [renew and press Enter. New IP information, (which might be the same address as before), is assigned. 10. Type ping IP_address, where IP_address is the address of FMC website or IP_address of another workstation in our Lab and press Enter. Is this IP address responding? If not, what might be the problem? Part B In this part, you will gain experience with TCP/IP troubleshooting commands.

To complete this project, you may use any type of workstation that has the TCP/IP rotator suite installed and is connected to the Internet. The following steps cover Windows, UNIX, and Linux workstations. Note that if your computer runs a newer version of Linux, you might have to replace outermost with trachea in the route tracing command syntax. 1. If you are using a workstation running a UNIX or Linux operating system with a GUI interface, open a shell prompt window. If you are using a workstation running the Windows operating system, click Start, select All Programs, click Accessories, and then select Command Prompt.

The Command Prompt window opens. . At the prompt, type neatest -a and press Enter. Recall that neatest is the command that reveals all TCP/IP port connections, even if they are not actively exchanging data. How many connections are listed on your computer? Many many connections. 3. Look at the State column in your connection listing. How does the value in this column differ for TCP connections? Why do you suppose this is the case? 4. Type neatest -s and press Enter. How many different TCP/IP core protocols are currently in use on your machine? Of those, which one sent and received the most packets?

TCP/IP protocols are in use on my machine. The IPPP sent and received the most. 5. Next, you experiment with another TCP/IP utility, the outermost function. If you are using a workstation running a UNIX or Linux operating system, type outermost www. Coinage. Com at the shell prompt, and press Enter. (With some versions of Linux, you need to use trachea or install the outermost utility. ) If you are using a workstation running Windows, type tracer www. Coinage. Com at the command prompt, and press Enter. How many hops does it take to go from your computer to he Coinage home page’s computer?

How many hops are listed as the maximum for the outermost (or tracer) command? 6. If you are using a Windows-based workstation, type tracer-d www. Coinage. Com and press Enter. This command instructs the utility to omit the host names of every hop between your workstation and the destination. Notice how the output differs from the output you received in Step 5 and describe it here 7. Next, run a outermost test and save the results in a text file called “traces. Txt” for later review. If you’re using a workstation running a UNIX or Linux operating system, yep outermost www. Engage. Com > traces. Txt and press Enter. On a workstation running Windows, type tracer www. Coinage. Com > traces. Txt and press Enter. The DNS server resolves the domain name to an IP address, and that address is listed, indicating you can reach at least one DNS server. This information tells you that your packets are traveling at least that far. Next, each hop (or router your packet passed through) is listed with the time in milliseconds the packet took to reach its destination. How many hops did the packet take to reach the domain you specified? Now try the outermost command to contact Compact’s Web server. Type outermost whom. Compact. Org and press Enter if you’re using a workstation running a UNIX or Linux operating system, or tracer wry.
