cvs login ( empty passwd )
cvs co dmmdb

From compressed packages

You can download source code in http://giss.tv/dmmdbp/

decompress the archive in a directory accesible to apache:

tar xvfz dmmdb-x.y.z-rc1.tar.gz

Dependencies

• php5

apt-get install php5

• apache2

apt-get install apache2

• mod_php for apache2

Configure your PHP installation

edit your php.ini file to set up the following parameters:

short_open_tag = On
session.cache_expire = 1000
post_max_size = 100M

(there you can customize your installation to set up the maximum size of the media you want to upload)

Configure your apache installation

You have to add the following line in your apache configuration:

AddHandler cgi-script .cgi

(this can be done in cgi.load for example)

and define the directory for cgis :

       <Directory "<yourpath>/dmmdb/cgi-bin">
               AllowOverride None
               Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
               Order allow,deny
               Allow from all
       </Directory>

this can be done in sites-enabled/[yoursite] if you use virtual hosts.

Check that the mime types on your system are correct

in your /etc/mime.types configuration file .ogg file should be decalred as application/ogg (and not like audio/ogg!)

/etc/mime.types :

application/ogg                                 ogx ogg

Edit config.php and change the parameters according to your installation

(parameters are quite explicit)
