If you’ve recently done an update on your debian or ubuntu Linux system, and you’re running dnsmasq, you might have noticed that it’s no longer responding to remote queries.
Check your /var/log/syslog
Do you have a line saying something like
dnsmasq: Ignoring query from non-local network
Well, thats because dnsmasq has decided to change the default behaviour for service DNS queries.
It will now only answer to itself by default Continue reading DNSMasq suddenly stopped working?
