how to connect from one ec2 instance to another ec2 instance through ssh
amazon-ec2, ssh, ssh-keys
Solution
I'd suggest you to create a special keypair for the tungsten user.
cd tungsten-user-home/.ssh
ssh-keygen -t rsa
mv id-rsa.pub authorized-keys
And then copy both files to the other host in the same place and permissions.
This will allow tungsten to work without requiring your own key.
