I'm having DNS resolution issues in various contexts which appear to trace back to my networking configuration.I'm running just the dnsmasq-base installation of dnsmasq on two Linux installations (Lubuntu 12.04 and 12.10). I haven't done anything in particular to configure dnsmasq, but I think some other changes I made previously may have lead to an incorrect configuration when upgrading.The working configuration on machine 'A' running 12.04 sets /etc/resolv.conf to use 127.0.1.1 (which in /etc/hosts is set to $HOSTNAME) On machine 'B' where certain applications such as OpenVPN experience DNS resolution issues, /etc/resolv.conf is set to 192.168.1.1, which is my gateway IP. Only certain applications are affected. Web-browsing, for example, works just fine. Any idea if this difference is the cause of the DNS resolution issues, and why 'B' is behaving differently?Edits:Both 'A' and 'B' are running dnsmasq, both are using DHCP to get DNS configuration, and I'm only using dnsmasq for DNS.There is no /etc/dnsmasq.conf file. I understand that this is normal when running just dnsmasq-base.The contents of /etc/resolvconf on the two machines appear to be identical. No extraneous/missing files.Sorry I can't be more specific about the nature of the problem. DNS resolution issue was the end-point of my discussion with technical support at my VPN provider.
Why is dnsmasq putting my router IP in /etc/resolv.conf instead of 127.0.0.1?
