Usage
.ssh/aws-proxy.sh [--profile profile] [--region region] [--key key] [--filter filterkey] user host [port]
Here filterkey is the name of the filter to the DescribeInstances
API call - it defaults to private-ip-address
e.g. if all your instances in the 10.1.0.0 subnet are in ap-southeast-2, you can use the following ~/.ssh/config
Host 10.1.0.*
User ec2-user
ProxyCommand sh ~/.ssh/aws-proxy.sh --profile test-account --region ap-southeast-2 --key ~/.ssh/test-aws %r %h %p
Host ip-10-1-*
User ec2-user
ProxyCommand sh ~/.ssh/aws-proxy.sh --profile test-account --region ap-southeast-2 --filter private-dns-name --key ~/.ssh/test-aws %r %h %p
