Quick notes on webpages

SSH to webadmin.oit.umass.edu
Your webpages reside in the directory named "public_html", which is a subdirectory of your home directory. (So you'll need to type "cd public_html".) Any files you create or put in public_html are viewable (by anyone) on the web -- if they know the URL.
To create or edit text files (like HTML code), use nano.
To see your website, go to http://people.umass.edu/LOGIN-NAME. For example, my website would be at http://people.umass.edu/pkirlin.
If you have a file called index.html (in the public_html directory), you'll see that webpage when you go to the URL above.
If you want to see a different file (or don't have a file called index.html), you must specify it in the URL. If it's in a different directory, you must specify that too.
For example, if you create a file called anotherpage.html, you should use the URL
http://people.umass.edu/pkirlin/anotherpage.html
to see it. Don't forget to change "pkirlin" to whatever your login name is.
If you're having problems, please come to office hours. It's very hard to diagnose problems over email when we can't actually see the way your files are set up.
