Heather,

Sorry for the delay in responding (last week was impossible for me
because of the trip I had to take).

I logged on as you and found:

[hwiseman at Hardy hwiseman]$ cd Local/HTML-Documents/

[hwiseman at Hardy HTML-Documents]$ chmod 644 4bit.gif 1lab1.html 

After the chmod we have:

[hwiseman at Hardy HTML-Documents]$ l 4bit.gif 1lab1.html
-rw-r--r--  1 hwiseman hwiseman 2427 Sep 22 14:29 1lab1.html
-rw-r--r--  1 hwiseman hwiseman 4172 Sep 29 16:43 4bit.gif

which makes those two files available to the public.

Your heather webpage_files/

also have the wrong permissions:

[hwiseman at Hardy HTML-Documents]$ l heather\ webpage_files/
total 16
drwx------  2 hwiseman hwiseman 4096 Sep 29 14:48 ./
drwxr-xr-x  3 hwiseman hwiseman 4096 Sep 29 16:43 ../
-rw-------  1 hwiseman hwiseman 8020 Sep 27 14:34 heather webpage.html

Since heather webpage_flies has a space in the folder name it is
necessary to quote the space with \ when referring to the folder name.
To change the permissions of the folder and the file inside we need to:

[hwiseman at Hardy HTML-Documents]$ chmod 755 heather\ webpage_files/
[hwiseman at Hardy HTML-Documents]$ chmod 644 heather\ webpage_files/heather\ webpage.html 

The 755 permissions are necessary for public folders while 644 are the permissions
needed for public folder contents.  If you go back to lab 0 and look at
the Unix tutorial, you will find reference to the commands I have used
here.

I'm taking the liberty of copying this message to the class discussion
list since many others are having trouble with file permissions.
