Apache and Lighthttpd both have a directory listing mod that you need to enable, often by default these are disabled for security reasons. You can enable indexing by doing the following:
Lighthttp
To enable directory listings globally:
dir-listing.activate = "enable"
If you need it only for a directory, use conditionals:
$HTTP["url"] =~ "^/download($|/)" {
dir-listing.activate = "enable"
}
Apache
To enable directory listings globally:
<Directory /usr/local/apache2/htdocs/listme>
Options +Indexes
</Directory>
However...
Directory indexing in both Apache2 and Lighthttpd do not support MDA SHA file hasing, its a simple directory view that allows you to download files, nothing more. You will need to use a PHP file manager or make your own using PHP MD5 File script. It's not a straight forward topic and your have to do some research, or pay for hosting with management.
