Strange permissions issue with files in Apache.


Hi All.

I'm having issues with directory listings in Apache on a CentOS 6 (x64) box.

The scenario:

I'm logged into the server as root, and am in the /var/www/html/mydir directory.

I've downloaded a file using wget from another server, but the file does not show in a directory listing when viewed from a browser.

The file permissions look to be good, and changing them to 777 does not help, however doing a cp filename newfilename against this file creates an identical copy that IS visible in a directory listing. The file permissions and ownership look identical, and I cannot see any difference between the two files. Am I missing something here?

Thanks.

What happens if you try to GET the file directly, like: http://myhost/mydir/filename
BTW you should use 644 for the files in the webserver and 755 for directories

Hi Bathory

Thanks for the reply.

So if I try a direct on the files, I get a 403 Forbidden (as expected):

You don't have permission to access /mydir/myfile.zip on this server.

Furthermore, I tried a known non-existent file, and received a 404 as I'd expect.

Also, to your point about permissions, 644 is what I have for the files - I gave 777 as an example to show that even the most permissive mode resulted in failure. File permissions are as below:

-rw-r--r--. 1 root root 361482835 Mar 25 12:09 myfile-copy.zip
-rw-r--r--. 1 root root 361482835 Mar 25 12:37 myfile.zip

Also I did an md5sum, and the checksums came up identical.

Thanks.

Doh strange indeed,
Check if there is something that forbids the specific filename in apache config file or in a .htaccess inside /mydir:
Code:
<Files myfile.zip>
Deny from all
</Files>

Yea weird huh?

No luck there either. Also, by moving to an intermediate filename, i.e.:

mv myfile-copy.zip myfile-copy2.zip
mv myfile.zip myfile-copy.zip
mv myfile-copy2.zip myfile.zip

I'm able to make myfile.zip downloadable, and myfile-copy.zip returns 403! Also tried:

ln myfile.zip test.zip

Which creates a hard link to the bad file, and that also returns a 403, so there's something about that file!

Since you're using Centos, it could be SELinux. Try
Code:
restorecon -r /var/www/html
and see how it goes

Great, SELinux is was! I ran restorecon against /var/www/html and both the bad file, and the hard link I created appeared in the listing!

Thanks a bunch for your help Bathory, that was driving me nuts for a while there!
