Custom dns for hotspot

[Tbaile]

Sometimes we need to change default dns for the hotspot (defaults are Opendns ones: 208.67.220.220 and 208.67.222.222). This is currently not supported, but it should be quite fast to do (no UI, only command line action for now).

The template file /opt/icaro/dedalo/template/chilli.conf.tpl already supports custom dns, we just would need to write the config file /var/dedalo/config where variables are taken.

I propose to use 2 new props in the dedalo db :

• dns1
• dns2

These props should write the /var/dedalo/config this way: HS_DNS1 ="dns1" HS_DNS2 ="dns2"

Additional considerations that took place during implementation:

• The feature doesn't set defaults by per se, only customization if needed
• Since the feature will be only shell side, no API calls have been implemented

I followed the documentation. After executing the commands, the DNS are updated:

grep '^dns' /var/dedalo/chilli.conf 
dns1            "1.1.1.1"
dns2            "8.8.8.8"
