A lot of things can be done with the firmware of Synology already. But sometimes an additional feature is needed that isn't supplied with the firmware. The solution to this is called ipkg (Itsy Package Management System). This is a package management system for your DS, which allows you to install additional software.

The ipkg software is plattform dependent, so please first check which processor is used on your DS. Which proccessor is on my DS?

Furthermore telnet or ssh access needs to be activated.

1. login to your DS via telnet or ssh, username is root with the password of the admin
2. change directory to /volume1/public.

   cd /volume1/public

3. donwload the correct ipkg installation file for your DS example:

   wget http://ipkg.nslu2-linux.org/feeds/optware/syno-x07/cross/unstable/syno-x07-bootstrap_1.2-5_arm.xsh

4. start the script

   sh syno-x07-bootstrap_1.2-5_arm.xsh

5. update the ipkg database

   ipkg update

6. restart your DS

After that the installation file can be deleted

rm /volume1/public/syno-x07-bootstrap_1.2-5_arm.xsh
