This NAS runs a busybox flavor of linux (using DSM5 in Synology parlance). I have installed Java with the Java Manager Package. Now, I look for a way to run the java process under a non-root account, while still allowing it to bind to the privileged Port 53.
I have looked into this great answer: https://superuser.com/questions/710253/allow-non-root-process-to-bind-to-port-80-and-443 but this does not work on my Synology box. I neither have
So the question is: How to specifically allow a process/binary to bind to a privileged port on a busybox linux?
