Comment 20 for bug 1367495

Thanks for the update. So I'm still really curious how that defaults file got so confused in the first place... It also may have something to do with why you're still having trouble..

If dnsmasq is still badly installed then that would explain your remaining issue.

What does:

sudo netstat -nr
ifconfig -a
cat /etc/

show in the container, and what does

ps -ef | grep dnsmasq

show on the host?

If the container eth0 does not have an ip address, then if you do

sudo ifconfig eth0 10.0.3.10 netmask 255.255.255.0
sudo route add -net default dev eth0
ping 10.0.3.1
