Subject Re: [users@httpd] Apache directory access & Suse AppArmor
Date Thu, 16 Oct 2008 02:55:16 GMT
Eric,

I got most of what you described but there are still something unclear to me.
If I want the WHOLE directory /images to allow view by the OS (AppArmor) and deny view via
the network by
every other network except net work 172.10.10.0/255.255.255.0 to read.   
Only allow network 172.10.10.0/255.255.255.0 to view or access.
What are the syntax look like?



Would this examples and steps work?


1. From Yast2 AppArmor
enable /srv/www/my-domain/images/ for read



2. From Appache configuration file, add the following lines:

  <Directory "/srv/www/my-domain/images/">
     Options None
     Order deny,allow
     Deny from all
     Allow from 172.10.10.0/255.255.255.0
  </Directory>





Thank you for helping clearing up my lack of understanding Apache2

Y

 Is this true?

It's true that making the files unreadable via the OS prevents Apache
from reading them.

You still have "/images/" instead of  "/srv/www/domainroot/images/" so
I suspect this stanza doesn't do anything.  You can use multiple Allow
directives.

They're largely irrelevant if you've configured the OS to not permit
Apache to read the files.

Your default config likely has examples.
