Getting a Secure-Shell (SSH) Client for Windows

Using a web browser, go to http://www.rm-rstar.com/eastoro/download/ and click on the 'putty.exe' link for your operating system. This allows you to download a single file (putty.exe) which you can save onto your computer. Run PuTTY by double clicking the file.

Connecting to Your UNIX shell account

Run PuTTY; it will pop up a dialog box that allows you to enter parameters. Under "Host Name", specify "rm-rstar.com", for "Protocol", select "SSH", and in the "Saved Sessions" box, type "My Shell". Press the "Save" Button; "My Shell" will appear in the list. Double click "My Shell" in the list to connect to your shell account.

Using the Joe Text Editor

Joe is a text editor, useful for modifying programs and scripts, including HTML files. Once Joe is running you can enter commands using a "control-sequence", which means you can press and hold the "Ctrl" key while pressing another key. In this reference, Ctrl is shown as "^".

Command Description
^K H Show or hide the help screen
^K D Save the current file
^K X Exit joe (saving if necessary)
^K C Exit joe, do not save changes
^A Move to the beginning of the current line
^E Move to the end of the current line
^K E Edit a different file

Of course, you can use the UNIX command "man joe" to read more about joe commands.

Basic HTML

HTML is a "Markup Language", which means it describes the layout and content of a web page. HTML is composed of tags, which tell a browser to do something, and data, which a browser displays according to the tags around it.

HTML tags contain attributes, which provide additional information about the tag. For example, the following is an "image" tag, with several attributes; it tells the browser to display the image "myimage.jpg":

<img src="myimage.jpg" width="320" height="200">

Many tags are actually pairs of tags - they have a "start tag" and a "closing tag". These tags surround the data that they describe. In the following example, we use the <strong> tag to show the phrase "This is Bold" in boldface, while "this is not" will be shown as regular text:

<strong>This is Bold</strong>, this is not

As you may notice, a closing tag is just like a start tag, except it begins with a "/". Also, tag attributes are only specified in the start tag.

These are some basic HTML tags, including their common attributes:

HTML Tag Description
<html></html> the start and end of HTML in a document
<head></head> the document header, which can contain a title
<title></title> the document title
<body></body> the start and end of the body of the html document
Attributes: bgcolor, text, link, vlink, alink
<p></p> the start and end of a parapgraph
Attributes: align
<font></font> the start and end of font settings
Attributes: face, size, color
<a></a> an anchor
Attributes: href (a URL)
<img> an image
Attributes: src (a URL), width, height, alt
<br> a line break

Viewing Your HTML File

Using a web browser you can navigate to http://rm-rstar.com/~username/ to see the contents of your public_html directory. If you have a file called "index.html" in that directory, it will automatically be displayed in the browser window.
