FAQs and Troubleshooting

Why do I see a "Forbidden Error" message?

Before you (or anyone else) can view your files in a web browser, you must change the access permissions for your home directory on opal. If these permissions are set incorrectly, anyone trying to view your webpage will see a Forbidden error rather than your content. Follow these instructions to set the correct permissions:

  1. Open an SSH connection to Opal or Ruby respectively. On Windows, you'll need to use an SSH client for this; on MacOS and Linux, you can open a Terminal window, enter "ssh your_onyen"at"opal.ils.unc.edu" (without quotes) and then enter your password when prompted.
    Once you've connected, you should see a command prompt like this:
    [your_onyen"at"opal ~] $ 

  2. Type chmod 711 . with both the space and the period and press Enter. If you get a "missing operand" error, make sure you included the space and the period at the end.

Your SSH client may have a permissions editor built in. If so, you can use it to set your home directory permissions as well. Be sure to change the permissions for your home folder and not public_html, and set them as below:

Still seeing an error?

Make sure your public_html folder, and any folders below it that you wish to have web accessible, are set to permission mode: 755. Below is a diagram of how your permissions should be set.

Note: chmod 711 command targets current folder. To change other folder permissions, navigate to that folder

How to password protect your webpage

If you'd like, you can require users to log in with an Onyen to view your webpages. To configure Onyen authentication for your opal.ils.unc.edu web space, follow the instructions in the ONYEN-AUTHENTICATION.txt file inside your home directory.

How to view your webpage

After you have uploaded your files and set the correct permissions, your webpage will be viewable at https://opal.ils.unc.edu/~onyen/ . This will take you to the index page in your public_html folder; you can also navigate directly to other pages or subfolders you've added, such as https://opal.ils.unc.edu/~onyen/my_folder/my_page.html
