requires familiarity with the options available in your area and their actual performance
1. Compile a list of ISPs in your town or city. If you live in a rural area with few
options, select a nearby city with more options so that you’ll be able to include some
of the private WAN technologies in addition to residential WAN offerings.
2. Check the website for each ISP to determine what broadband services they offer in
your area, both for residential customers and corporate customers. Include both wired
and wireless options. Answer the following questions:
a. What are their advertised speeds?
b. How much does each solution cost on a monthly basis?
c. What installation fees are there, if any?
Answer: Answers may vary.
d. How far away are you located from their CO? (If you’re researching another city
besides your own, use a fictional location in that same city.)
Answer: Answers may vary.
e. What effect will this distance likely have on the actual speeds of each service
option?
Answer: Answers may vary.
3. Search online for consumer reviews of each ISP in your list. What kinds of ratings
does each ISP receive online?
Answer: Answers may vary.
Project 12-4: Configure TCP/IP in Ubuntu Server
In this project, you will learn to configure TCP/IP in Ubuntu Server. Ubuntu stores
TCP/IP configuration settings in the /etc/network/interfaces text file. These settings are
persistent, which means they are used each time a NIC reconnects to the network. You
can temporarily change TCP/IP settings by using the ifconfig, route,
nameserver, and other commands and by editing the /etc/resolv.conf text file. Using
the Ubuntu Server VM you created in Chapter 4, Capstone Project 4-1, follow these steps
to examine TCP/IP settings and temporarily change these settings.
1. Start the VM and log on to Ubuntu Server.
2. To view the current TCP/IP settings, enter the command ifconfig.
3. Write down the IP address, MTU, network mask, and MAC address for the active
network connection (not the loopback).
5. Ubuntu temporarily stores the IP addresses of name servers in the /etc/resolv.conf
file. Enter the command cat resolv.conf to view the contents of this file.
6. Write down the IP addresses of the current DNS name server(s).
Answer: Answers may vary.

8. Enter the command cat interfaces to view the contents of the
/etc/network/interfaces file.
9. What is the name of the primary interface? It might be eth0, enp0s3, or something
similar.
10. Enter the command route –n to view the IP address of your current default
gateway.
11. Recall that 8.8.8.8 is the IP address of one of Google’s public DNS servers. Enter
12. Now let’s make some temporary changes to the TCP/IP configuration. Change
your IP address to 10.0.0.100 and your network mask to 255.255.255.0, using the
following command, and then enter your password:
13. Most likely, you will no longer have Internet connectivity. To verify that is the
14. Enter the command sudo ifdown <primaryinterface> to release the
current TCP/IP settings for the primary interface.
15. Enter the command sudo ifup <primaryinterface> to renew the
network interface using the persistent TCP/IP settings for that interface.

about your activities in this project.
Capstone Project 12-2: Organize Wikidot Website
Throughout this text, you’ve kept notes on various projects in your Wikidot website. To
finish up these projects, let’s do some final cleanup and organization so these notes will
continue to be useful and easily accessible for you as you move into your other IT classes
and your career. You might decide to continue adding notes, pages, and categories, or
create new wikis as needed. Using good organization and adding thorough notes could
make your wiki a valuable exhibit when applying for your first job in IT. Complete the
following steps:
1. Let’s first adjust the side navigation menu. On the All Pages page, click Side
Navigation and then click Edit. You should see the text shown in Figure 12-31.
Throughout this project, you can ignore any red, squiggly lines in the text.
2. Let’s change the User Guide link to point to the list of all pages instead. On the
User Guide line, edit it to read:
3. When you’re finished, the edited text should look something like what is shown in
Figure 12-32. Save your changes and test the new link.
Each time you named a page with one part before the colon and another part after the
colon, such as Applications:Wireshark, you added that page to a category. The first name,
such as Applications, is the name of the category. The second name, such as Wireshark,
is the name of the page.
4. To see a list of all categories in your wiki, click the gear icon, then click Site
Manager, Appearance & Behavior, and Navigation elements. Click the drop-
19
5. Go back to your wiki, and create a new page called system:All Categories.
7. Go back to the All Pages list. The All Categories page is listed as “system:All
Categories.” To list this page as “All Categories” instead, click the system:All
Categories page, click Edit, and change the title of the page to read All
Categories. The name of the page still includes its category (system), but now the
title of the page will show only “All Categories.”
This module automatically creates a list of all the categories and all the pages within each
category. If any page is listed in the wrong module, you can’t edit the page’s title to
8. To change a page’s category, go to the page and click + Options, then click
Rename. Change the page’s category, which is the name before the colon, and
click Rename/move.
Now let’s edit the top navigation bar so it shows one or more categories as an option, and
9. Click the gear icon, and click Edit Top Bar. Then click the Edit button on this
page. You should see text similar to what’s shown in Figure 12-33.
Currently, the only link in the top navigation bar that gives a drop-down menu is the Help
Docs link. We want to remove some of the links in the top navigation bar and add a drop-
down link for each category.
10. Delete the Layout and Membership lines in this text.
11. Change the text User Guide to All Categories. Change its location to system:all-
categories. The line should now read:
12. Change the text Help Docs to the name of one of your categories, such as
Applications.
13. For each sub-item, add the name and location of a page within that category. For
example, the Wireshark page would be listed under Applications like this:
[[li]][[a href=”/applications:wireshark”]]Wireshark[[/a]][[/li]]
14. On the Applications line, change the text that reads “fa fa-question-circle” so it
15. On the About line, change the text that reads “fa fa-info-circle” so it says “fa fa-
question-circle”.
16. When you’ve made all these changes, look over it again to see if you can find any
17. Test each link to make sure it works correctly, and troubleshoot any problematic
links. To make changes, go back to the Top Navigation page and click Edit. The
edited text should look something like Figure 12-34. Make sure the page
addresses are typed exactly right. Replace any spaces in the page’s name with
hyphens. For example, change “Packet Tracer” to “Packet–Tracer” with the
hyphen in place of the space.
18. Add more categories and pages links, as desired, until you’ve listed all your
categories and pages that you created for projects in this text.
19. On the top navigation bar, add a link to the All Pages page, with an information
circle next to it. This link will make the All Pages page accessible directly from
the Home page. What line of code must you add to the top navigation bar’s code
to accomplish this?
20. Edit the Home page text and the About page text to reflect what you’ve
accomplished during this course and to describe the information available through
your wiki. Make any other changes you would like to the navigation menus,
