Linux based network server

2. Assume that you are hired as the Network Administrator for a small company. The 4 current employees have 3 Windows computers and 1 Mac computer. However, the business is growing and hiring 10 more employees. The business owner wants to set up file and print sharing for the employees, and set up a web server to sell their products on the Internet. Would you suggest implementing a Windows based network server or a UNIX/Linux based network server? Of course you must explain your suggestion if you want to receive full points for this question.

3. It would be difficult for a user to tell the difference between a UNIX server and a Linux server if all they were doing was typing commands.

True

4. True or False. The Courts in the United States have determined that UNIX and Linux are the same thing as far as Intellectual Property rights are concerned.

7. What key(s) or character(s) do you have to use to get out of the man page utility? A. exit B. x C. q D. Q

8. What will be returned if you type: apropos delete user A. Every man page that has the word delete OR the word user B. Every man page that has the words delete AND user. Either word can be anywhere on the line. C. Every man page that has the exact phrase “delete user”. The words must be in that order, with

just one space between them. D. A portal to another dimension will open

9. What would you type to see all the files in the current directory?

10. Assume you are in your home directory. What UNIX command do you use to see a listing of all the files in the directory /usr/lib ?

11. While a directory may seem empty because it doesn’t contain any files or sub-directories, you will always see two items if you use the command to see all files. What are the names of these two items, and what are they?

12. What you would type on the command line to move to the directory above the current

directory?

13. What you would type on the command line to move to your home directory?

14. What you would type on the command line to move to the directory /etc/rc.d ?

15. What you would type on the command line to move to a subdirectory of the current directory named junkDir? (You can assume that junkDir exists.)

It only works on files that have lines that are 40 characters or less. C. It only works on files that have an extension of “.txt” D. The cat command sends the entire file to the display.

18. True or False. UNIX follows the same 3 letter file extensions as Windows. That is, it uses .exe, .doc, .jpg etc.

21. When you delete a file using rm, how do you get it back out of the trash if you change your mind? A. Go to the trash folder in your home directory and move or copy the file.

B. Use the undelete utility C. Run rm -recover filename, where filename is the name of the file you want to

restore D. There is no trash and no way to recover the file without using special recovery software.

22. Why can’t normal users, that is a user that is NOT an admin or superuser, change their user id (uid)? A. They CAN change it by using the usermod command B. The uids must be assigned in sequence, and only the admin knows which uid should be the

next to use C. This would cause security issues as any user could impersonate any other user by simply

changing to their uid D. The user may try to use a uid that has already been assigned and this would cause the OS to

crash.

23. Explain the difference between how umask and the chmod command affect your permissions? A. There is no difference B. The umask command only affects files that already exist, while chmod changes your

39. Assume that you are in vi. What would you expect to happen if you typed the following: <esc>:-5,+5 s@^[email protected]@

(You should be able to look at this and determine what will the command is saying. If you want to test this you will should create a text file with at least 20 lines, and put the word “tony” on every line. Some of the lines should have “tony” as the first word on the line, but it should not be the first word in other lines. Position yourself about halfway through the file before running the command.)

40. Explain this step by step: This question requires you to perform the following hands-on tasks on your account on the CBC Linux server. Make sure and follow the instructions very carefully, especially the last instruction. I will only check for a file named “all.done”, so if you name your file something else you will not receive credit for this question.

Also remember that if the Linux server supports FTP (WinSCP), you can always move the file to your Windows PC or Mac, perform the tasks, then copy the file back to the Linux server.

A.Copy the file /home/test2.txt to your home directory.

B.Remove all of the tab (^I) characters. (Hint: it may be easier to do this if you can see the tabs.)

C. Edit the file and add two lines at the top of the file which contain your name (on the first line) and the “Geek In Training” (on the second line).

D. In the first 30 lines, change all occurrences of the phrase “WWW” to the phrase “Santa Claus is coming to town”.
