Directory Domain Restriction
This should help you set up protection on a directory in UBWings. It is adapted from the NCSA Mosaic User Authentication Tutorial for UBWings Information Providers.
The example below shows you how to set up access restrictions to a directory based on the domain that your visitors are coming from (in other words, you can use it to "lock out" non-UB computers).
There are several simple steps:
- Where is your directory and what is it called?
Log in to your Unix account and go to your departmental directory on Wings (e.g. type
cd /net/wings/info/www/whereveryourdirectoryis). Find the name of your Unix subdirectory by typing:pwd
This will return the "present working directory" - we'll call it "home" from now on when we need to reference it.
- Create a new subdirectory off your home directory by typing:
mkdir xxxxx (where xxxxx is the name for your new directory)
This new direcory is /home/xxxxx and will hold the files you wish to protect.
- Move into the new directory xxxxx:
cd xxxxx
- This seems to be the most difficult part. Follow the instructions
and you will have no problems.
Create a file called .htaccess in directory xxxxx that looks like this:
order mutual-failure
allow from .buffalo.edu
deny from freenet.buffalo.edu
Save it and exit the editor. OK, .htaccess is done!
- Set the directory permissions. At the Unix prompt, type:
chmod a+rx /home/xxxxx
chmod a+r /home/xxxxx/.htaccess
That's all. Now put some files in the directory /home/xxxxx/ and try to access them -- your browser should show the files if your computer's domain is .buffalo.edu. If possible, have a friend from outside UB try to access the files.
