  • Students will no longer be provided an @cs.siu.edu email address.
  • Students should phase into using strictly their @siu.edu email addresses.


Create Your Own Website and Run CGI/PHP/JSP/Servlet Scripts

  • How to post your webpage
    • Log on to a Linux computer or SSH to pc00.cs.siu.edu or pc01.cs.siu.edu.
    • In a terminal, make sure there is a directory called public_html under your home directory.
      • ls -l ~
    • If not, create the directory with this command "mkdir ~/public_html" (without "").
    • In a terminal, use following two commands to make sure the permission of your home directory and public_html folder are correct.
      • chmod o+x public_html
      • chmod o+x /home/your_login_id
    • Put your index.html and other website files under the public_html directory you just created.

      Detailed instructions with screenshots.

    • Use a browser like Firefox or Internet Explorer to open your webpage. The URL is: http://www.cs.siu.edu/~your_login_id/
  • How to run your cgi scripts
    • Refer to How to post your webpage above and make sure you follow all steps.
    • Create a directory called cgi-bin under your public_html directory.
    • Change the permission of the cgi-bin directory to others readable and executable.
