I googled online however I did not find a clue my question. So I post
it here.

I created a mod_python CGI to upload a file and saves it in folder "/
var/www/keyword-query/files/".  My code runs in root.

     fileitem = req.form['file']

   # Test if the file was uploaded
   if fileitem.filename:

      # strip leading path from file name to avoid directory traversal
      fname = os.path.basename(fileitem.filename)
      # build absolute path to files directory
      dir_path = os.path.join(os.path.dirname(req.filename), 'files')
      f = open(os.path.join(dir_path, fname), 'wb', 10000)

      # Read the file in chunks
      for chunk in fbuffer(fileitem.file):
      message = 'The file "%s" was uploaded successfully' % fname

I got:

 File "/var/www/keyword-query/", line 30, in upload
    f = open(os.path.join(dir_path, fname), 'wb', 10000)

IOError: [Errno 13] Permission denied: '/var/www/keyword-query/files/

"Defrosting.rtf" is a file on the desktop of my Windows XP computer.

Anybody knows what the problem is?

Thanks for your replies.
