How To Create and Maintain an Audit Website

Spring 2007

For the purposes of this discussion, we'll assume that your username is astudent and that you are a member of group olive. (So wherever astudent occurs below, substitute your actual username on warp, and wherever olive occurs below, substitute your actual group name.)

1. (I'm assuming that you've made the change to your .bashrc file described at the beginning of Lab 18; if you haven't, go ahead and make the change, save the file, then log out and then log back on to warp.)

   When bash asks you
       Are you planning to work as part of a web audit group?
   respond
       y

   What you should see:

   Files will be created u=rw(x),g=rw(x),o=r
   Primary group is now olive.

   If you don't ...

   Have you logged out and back in? Did you copy the correct text into your .bashrc? If you still can't get this to work, send me an email.

2. Make sure that warp knows that you are a member of group olive.

   How:

   Enter groups at the bash prompt.

   What you should see:

   astudent olive

   If you don't ...

   Send me an email —you can't fix this yourself.

3. Find the location of your group's audit website in the warp filesystem.

   How:

   It is located at /projects/audit-groups/2007/olive/public_html

4. Copy your audit files from your personal webspace on warp to your group's webspace.

   How:

   Make your public_html directory the working directory:
   cd ~/public_html

   cp filename /projects/audit-groups/2007/olive/public_html/.
   (That's not a period—you need the dot.)

5. Check to make sure your copied file has the correct group association.

   How:

   cd /projects/audit-groups/2007/olive/public_html

   ls -l filename

   What you should see:

   -rw-rw-r--   1 astudent olive    207 Apr 22 10:09  filename

   If you don't ...

   chgrp olive filename

6. Check to make sure your copied file has the correct group permissions.

   How:

   cd /projects/audit-groups/2007/olive/public_html

   ls -l filename

   What you should see:

   -rw-rw-r--   1 astudent olive    207 Apr 22 10:09  filename

   If you don't ...

   chmod g=rw filename

7. Check to make sure your copied file is world-readable.

   How:

   cd /projects/audit-groups/2007/olive/public_html

   ls -l filename

   What you should see:

   -rw-rw-r--   1 astudent olive    207 Apr 22 10:09  filename

   If you don't ...

   chmod o=r filename

8. (Remember ... only a file's owner can change its group or set its permissions. Further, the way things are set up on warp, only a file's owner can rename or delete the file. If you followed the above instructions, however, everyone in the group can modify the file.)
9. View your file over the web.

   How:

   Go to the Websites Containing Audit Documents webpage; select the appropriate link, then modify the address bar to include the name of your file in the URL.

   What you should see:

   After you're prompted for a username and password, the page should load into your browser.

   If you don't ...

   Make sure your file is world-readable.

10. Repeat as necessary.
11. If you create directories in your group's audit webspace, don't forget to make sure that the permissions are suitable for web access.

    How:

    cd /projects/audit-groups/2007/olive/public_html

    mkdir dirname

    ls -ld dirname

    What you should see:

    drwxrwsr-x   1 astudent olive   1024 Apr 25 16:22  dirname

    If you don't ...

    chmod a+x dirname

12. Don't forget that all files to be served out over the web must be world-readable—this includes any stylesheets or image files.

If you've followed these instructions and you're still having problems, contact me. In your message, be specific about where you've run into a problem.
