Oracle Compute Cloud. Add the nameserver to /etc/resolv.conf for an interface with a private ip on the shared network
# get the IP address for eth0
private_ip=$(/sbin/ifconfig eth0 | grep 'inet ' | awk '{ print $2 }')
# shared network private IPs are in a /30 subnet, nameserver is IP address -1
nameserver=$(echo ${private_ip} | awk -F. '{ sub("."$4,"."$4-1) } 1')
# append to /etc/resolv.conf
sudo sed -i -e "\$anameserver ${nameserver}" /etc/resolv.conf
