Personal Web Pages

If you have an account on shell.iptel.org then you can create your own web pages there. The contents of home directories is shared across servers using NFS and thus it will also become immediately visible on all the web servers.

Directory and Permissions

Do the following if you want to create your own webpages:

1. Create directory named public_html in your home directory
2. Make sure that your home directory and public_html subdirectory can be accessed by anyone
   (chmod a+x /home/username /home/username/public_html)
3. Place your HTML pages in public_html subdirectory of your home directory.

Your webpages will be available at http://iptel.org/~username or http://www.iptel.org/~username.

The system running at iptel.org is powered by Drupal content management system. Drupal makes the management of the site easy and hopefully it will be easier for us to keep it up-to-date. This page should give the reader overview of the whole system, including how the pages are created, stored, and managed. After reading this page you should see the "big picture" and you should be able to lookup additional information if needed.

Nodes

In Drupal web pages are stored in MySQL database in form of nodes. Node is the basic piece of content in Drupal. When a new page is created then Drupal creates a new node and stores it in the database. For the sake of clarity you can assume that node is equivalent of page (and yes, we know this is not always true).
