[Cerowrt-devel] [Dnsmasq-discuss] Names not resolved on Wireless

[Simon Kelley]

I'm not sure that's the problem, but it's worth a try.


Another thing to do is add a a line to log if bindtodevice() in 
src/dhcp-common.c actually sets the SO_BINDTODEVICE sockopt. It's not 
supposed to even is there's currently exactly one interface, if there's 
a possibility that more will appear. This could be relevant in this 
case, but I'm not sure where the regression could come from.

Hmm, are you using --listen-address or --interface to configure dnsmasq 
to server particular interfaces? Or maybe --except-interface? Now 
there's a thought.....

Simon.
