Use hotspot and captive portal without internet (eth0)

[mcpeixoto]

Heya!
I've installed coova-chilli on a raspberry pi 3 using this script: https://github.com/pihomeserver/Kupiki-Hotspot-Script

I'm trying to use the hotspot and captive portal without internet but when I disconect the device (unplug eth) the captive portal stops working (Dosen't pop up on the phone for example).

I'm running a custom wordpress website as captive portal.

More detailled information here:

What are the DNS servers set in chilli conf ?

"208.67.222.222" and "208.67.220.220", the default of the script I'm using. OpenDNS I beliave

How can I solve the problem of not poping up?

You should use local DNS in the same network than your internal webserver : 192.168.10.X

If no internet access, chilli cannot resolve anything with your current DNS config.

Can't I make the raspberry "auto-resolve" chilli itself?

[cschnatz]

Chilli and the client need to resolve the portal page URL to start and get redirected. I've used dnsmasq to build a black hole for every dns request and answer it with the captive-portal-ip.

Can you send me some links/more info?

@acujl : maybe something like that : https://serverfault.com/questions/351108/using-dnsmasq-to-resolve-all-hosts-to-the-same-address ?
