Today I was planning on upgrading from Stonburner to the latest version. I noticed none of the repositories could be reached.
A quick test showed DNS not working at all. Ping to google.com fails while a ping to the IP 188.8.131.52 works fine.
I manually added my routers IP and 184.108.40.206 as DNS servers for my system.
Secondly both the /etc/ifconfig/interfaces and etc/resolv.conf files are completely empty.
