Title:
DNS Querying fails if any DNS server is unreachable
Status in “dnsmasq” package in Ubuntu:
Confirmed
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
Release: 12.04
Hardware: HP Compaq 6910p Laptop
If the backup DNS server is unreachable, dnsmasq does not try to reach
primary DNS server.
In the following default configuration (clean install of 12.04) 1 out
of 4 DNS queries fail. (DNSMasq seems to rotate queries between the
listed servers)
wlightning@archon:~$ cat /run/nm-dns-dnsmasq.conf
server=75.75.75.75
server=75.75.76.76
wlightning@archon:~$
wlightning@archon:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
