If you want any program or some kind of service that will start at startup in Debian follow these steps.
Check if your program runs like this
/etc/init.d/(program name) start
Make sure that your script is actually the /etc/init.d directory and then issue the following command
update-rc.d (program name) defaults
chmod 775 /etc/rc2.d/(program name)
ln -s /etc/init.d/(program name) /etc/rc2.d/(program name)
Done !!!
Example : I used the Wowza Media Server as example
Check if your program runs like this
/etc/init.d/WowzaMediaServer start
Make sure that your script is actually the /etc/init.d directory and then issue the following command
update-rc.d WowzaMediaServer defaults
chmod 775 /etc/rc2.d/WowzaMediaServer
ln -s /etc/init.d/WowzaMediaServer /etc/rc2.d/WowzaMediaServer
And Done
