Publishing Your Website Using Your Home Directory

You can publish a website by putting your website files inside a folder called html inside your Public folder. Your website can then be viewed at this URL:

http://www-personal.umich.edu/~youruniqname/

Subsitute your own uniqname for "youruniqname" above.

You can use the web sites button to set up your webspace and then to get to your html folder quickly.

Creating Space for Your Website

1. Click the web sites button.

   

2. If you do not yet have an html folder for your web pages, or if there are problems with the permissions for your web pages, you will be prompted to create the space and fix any problems before proceeding.

   

Check the checkbox(es) next to the names of websites you want to set up, then click the prepare selected web spaces button.

1. Your web space will be set up for you.

   

Note It is helpful to be able to distinguish between your public and private websites; your public site is published on the web for anyone who wants to view it. Your private site is set up so that only members of the U-M community can view it. They will be prompted to log in with their uniqname and UMICH Kerberos password (or Friend ID and password) before they can see it.

Navigating to Your Website Folder

1. Click the web sites button.

   

2. Click the name of your web space to go to the folder in your AFS space where your website is published. Put the files for your web pages in that folder to publish them.

   

Creating a New Folder

1. In the Actions list, click Create a New Folder.

   

2. In the Create a New Folder box that opens, type a name for your new folder, and then click the Create button.

   

Setting Folder Permissions

You can set permissions for the folders inside your home directory. For example, you might create a folder in your AFS home directory that you want to use for a group project. You could then set permissions for that folder to allow only your group members to see what is inside it and make changes.

1. Put a checkmark in the checkbox next to the name of the folder for which you want to set permissions, and then, in the Actions list, click the Set Permissions for Folder link.

   

2. In the Permissions Manager pane that opens, you will see the existing permissions for the folder. In this example, the owner of the folder (jtestusr) has all permissions.

   

   Definitions of permissions:

   lookup: If you have lookup access to a folder, you can see the names of documents and folders inside it, but you cannot open and read them. A user must have lookup access rights in order to use any other rights. If, for example, you assigned read rights on a folder to a friend but did not assign lookup rights, your friend would not be able to see the documents in the folder and would therefore not be able to select any to open and read.

   read: If you have read access to a folder, you can open and read any document inside that folder (assuming, of course, that you have the right application, such as Word or Excel, to open it).

   write: If you have write access to a folder, you can make and save changes to any document it contains.

   insert: If you have insert access to a folder, you can add new documents and folders to it.

   delete: If you have delete access to a folder, you can delete any documents or folders it contains.

   lock: If you have lock access to a folder, you can place read or write limitations on it. This permission is rarely used. It allows you to lock a folder while you are updating a document inside it so that no other user can alter the document until you release the lock.

   admin: If you have admin access to a folder, you can change the permissions for it and the folders it contains. You have admin rights for all folders inside your AFS home directory, but you cannot change the access privileges for your home directory itself.

3. To add someone and set permissions, type the uniqname of the person you want to add in the box at the bottom of the list, set the permissions you want, then click Save Permissions.

   

4. The new permissions will be added to the list. You can add more people, one at a time. When you are finished setting permissions, close the Permissions Manager pane by clicking the [X] in the upper right corner.

   

To remove permissions, uncheck the respective check boxes as appropriate. To remove someone entirely from the list of users with permissions for a particular folder, uncheck all the permission boxes next to that person's uniqname, the click the Save Permissions button.

Group permissions. You can give permissions to groups by using pts group names. For details about creating pts groups, see Creating and Using Protection (pts) Groups for AFS.

About negative rights. At the bottom of the Permissions Manager, you will see a section for negative rights. This can be used in conjunction with pts groups. If, for example, you have give access permissions to a pts group, but you want to deny that access to one member of the group, you can use negative rights to do this. When you give someone negative rights to a folder, you are denying them access.
