How do I logon to the CS server so I make Web pages?
1. Windows PC: Start putty (see Question 1 above), Fill in the connection window, and login to the cs server with your user name and password.
  OR
2. Using a terminal in Rooms 015, 017, or 019 in Root Hall:
  Enter your user name and password to login to the terminal. All your work will be mirrored to the cs server.
  Important the terminals are NEVER cut off. When you have finished your work, enter the command:
  exit
  to end your session on the terminal.
  OR
3. Apple Macintosh: Use the finder to locate the terminal application. It is in utilities sub-directory of applications. Double click on the terminal application to start it. You will get a terminal window. Enter the command:
  ssh cs170dd@cs.indstate.edu
  where you replace the d's with your user name digits. This connects you to the cs server. It will ask for your password. Type enter it. Again the password will NOT be displayed.
How do I Log Off the CS server? When you are finished working on the server, get back to the command prompt. (for instance if you are still in pico-- see below-- type ^X to get out of pico) then enter the command
exit
That is type exit and press the return or enter key.

Using a file editor (pico); Making a small file. Your files are to be in your home directory. So the first step is setting the current directory to be your home diretory. If you have just logged on to the cs server, then you are already in your home directory. You should see

The simplest way of doing this is to enter the command
cd
We are going to make a file named summer.txt This will be our first Webpage! We start our work by entering the command:
pico summer.txt
This command starts the pico editor program which will let you write or change file summer.txt.
Unlike the other unix commands you have seen, pico does not immediately finish. It waits until we tell it we are done writing.
The upper part of the pico screen is where you type in the file content. The lower two lines list several pico commands you can use.
-----------------The two important pico commands------
```
^O   Write Out
^X   Exit
```
The caret (^) in front of each command means hold down the ctrl (or control) key when typing the letter that follows.

^O: To SAVE your work (Write Out) you hold down the ctrl key when you type the O key. When you do this, pico responds with the line:
File name to Write: pg1.html
The file name that appears is the name you typed in the when you started pico. Mostly you will just press enter to accept the name,
but you have the option of backing up, changing the file name, and THEN pressing enter which writes your work to the new file.

^X: To EXIT pico, you hold down the ctrl key and type the X key. If you do this after you have done the ^O command, pico will return you to the unix command line.
But if you have not saved all that you have typed, pico gives you the option of saving your recent changes before returning to the unix command line.
---------------------------------------------

In the pico window type:
```
<!DOCTYPE html>
<html>
<head>
<title>Actual First Page </title>
</head>
<body>
<h1 style="color:red; text-align:center;">Hello, World!</h1>

<p>
This is a first line that is short.<br>
This is the second line of the paragraph and it is
longer; in fact it keeps going and going. Finally the
third and final line, good bye.
</p>

</body>
</html>
```
Once all of the above has been typed, type the command ^O then press the enter key to save your work to the file pg1.html. Finally type ^X to exit pico.

View your Webpage! Start a browser. Enter the address: cs.indstate.edu/~cs170dd/pg1.html.
Make sure that you put in your digits in place of the d's in cs170dd.
You should see a web page with a red centered
Hello, World
and a three sentence paragraph.
