Searched with google, but didn't find anything. Now the next hurdle, when we are pushing it to powerbi service. With ssh-agent running locally and usable, the keys ssh-add‘ed to it so that they are unlocked, each machine having the correct public key in it’s ~/.ssh/authorized_keys, and ssh agent forwarding enabled for the bastion host, you should be able to ssh through the bastion host and then ssh from there into the destination machines: my_machine# To do this on PuTTY, you set up a config to your bastion host with a port forwarding set up. ; WinSCP is a Windows GUI for secure file transfer that has SFTP support.

In order to access your server via SSH tunnel you need an SSH client. Port Forwarding makes use of an SSH tunnel, which allows connections to a remote server to be facilitated by binding to a local port. When someone accesses the port 1234 on the SSH server, that traffic will automatically be “tunneled” over the SSH connection. All other ports should be blocked. Bastion host needs access to the SSH port 22 on linux server and RDS port 3389 on the windows server so that it can be used for remote access to these machines. For this example, I have created one security group for both types of instances. The fact that your workstation cannot see Prince does not matter, it only needs to see its end of the tunnel.
