I have a Hotspot configured to share my wired Internet connection with other devices, the hotspot is started using
nmcli con up Hotspot ifname virtual.
The hostspot is up and use the IP
At this point all works fine, any device can connect to the hotspot and use the internet.
Now I'm trying to setup
dnsmasq to access to some virtual hosts in my computer from my phone, but when try to start the service I got the following error:
dnsmasq: failed to create listening socket for 10.42.0.1: Address already in use
I can see "some" process already listening on port 53
netstat -anlp | grep LISTEN | grep 10.42.0.1:53 tcp 0 0 10.42.0.1:53 0.0.0.0:* LISTEN -
The hotspot is launching some dns server?, can disable this to use
dnsmasq or at least configure to read hosts from
