I have created a own hotspot on my raspbery pi. When a device is connected to the raspbery pi hotspot then the meaning is that his browser will automatic open and goes straight a ahead to the landing page. How is that possible? Is that a DHCP option or something else? My current situation is: device is connected. User start by them self the browser and go to any url. the DNS server on my raspberry PI match on every domeinname. But this steps must be automatic, so the only work what a user is doing is connecting to the hotspot SSID. The rest must be automatic. Pls help!
