Disable root login for dropbear?

Question

Linux noob here. How can I disable root login for dropbear? What I've done so far

adding DROPBEAR_EXTRA_ARGS="-w -g" into /etc/default/dropbear (not working)
adding DROPBEAR_EXTRA_ARGS="-w -g" into /etc/init.d/dropbear (not working too)

Dropbear version dropbear-0.58-1.el6.i686.rpm installed on centos 6.

Please help.

Thanks

Sorry, this just popped straight to my mind.. have you restarted the dropbear service? — Isaac Kwan, Aug 05 '13 at 09:30
Do those options actually get added to the process when it's restarted? You can check with `ps -ef | grep dropbear`. — Ladadadada, Aug 05 '13 at 09:59

Based on looking at the /etc/init.d/dropbear script from dropbear-0.58-1.el6.i686.rpm I'd say you need to have the following line in the config file /etc/sysconfig/dropbear:

OPTIONS=-w -g

After modifying the file, restart the dropbear service. If all goes well, using ps -efw | grep dropbear should show that the options have really been passed to the executable.
