```bash
echo "127.0.0.1 s3.amazonaws.com" >> /etc/hosts
echo "127.0.0.1 s3-us-west-2.amazonaws.com" >> /etc/hosts
echo "127.0.0.1 s3-us-west-1.amazonaws.com" >> /etc/hosts
echo "127.0.0.1 s3-eu-west-1.amazonaws.com" >> /etc/hosts
echo "127.0.0.1 s3-ap-southeast-1.amazonaws.com" >> /etc/hosts
echo "127.0.0.1 s3-ap-southeast-2.amazonaws.com" >> /etc/hosts
echo "127.0.0.1 s3-ap-northeast-1.amazonaws.com" >> /etc/hosts
