For instances that are hosted on Google Cloud, add to the allowlist the IP addresses that match your region. Looker-hosted instances are hosted on Google Cloud by default. By default, this will be the United States. The second step is to allow network traffic to reach the tunnel server or database host via SSH, which is generally on TCP port 22.Īllow network traffic from each of the IP addresses listed here for the region where your Looker instance is hosted. Can be accessed from the Internet via SSH.The tunnel server can be any Unix/Linux host that: Conclusion We have shown you how to set up SSH tunnels and forward the traffic through a secure SSH connection. Setting up public key authentication allows you to connect to your server without entering a password. We recommend that you remove all non-essential software and users from the tunnel server and closely monitor it with tools such as an IDS. Once you enter your username and password, you will be logged in to your server, and the SSH tunnel will be started. If the tunnel server is compromised it is one step removed from the database server. This will allow Stitch to authenticate via a public key and connect to the server. Next, you’ll create a Stitch user on the SSH server. To use SSH on Windows, you’ll need to install an SSH client like OpenSSH. Terminating the tunnel on a separate server has the advantage of keeping your database server inaccessible from the Internet. Note: This section assumes your SSH server is Linux or Ubuntu-based. The disadvantage is that your database server may be on a protected network that does not have direct access from the Internet. A guide to securely access private database or application servers from your local workstation What is an SSH Tunnel SSH tunnel aka SSH port forwarding enables. There is one fewer host involved, so there are no additional machines and their associated costs. Terminating on the database has the advantage of simplicity. The tunnel can be terminated on either the database host itself, or on a separate host (the tunnel server). The first step to set up SSH tunnel access for your database is to choose the host that will be used to terminate the tunnel. Step 1: Choose a host on which to terminate the tunnel BigQuery and Athena users should skip directly to database configuration. SSH Tunnels are unavailable for databases that lack a single host address, such as Google BigQuery and Amazon Athena databases. Save money with our transparent approach to pricingįor the strongest encryption between Looker and your database, you can create a SSH tunnel to either a tunnel server, or the database server itself. You can then configure your Internet browser to use an add-on such as FoxyProxy or SwitchyOmega to manage your SOCKS proxy settings. To create Tunnel 1: To create Tunnel 2: Once Tunnel 1 is started, then start Tunnel 2. Then, click New SSH tunnel and create Tunnel 1 and Tunnel 2. Rapid Assessment & Migration Program (RAMP) In the main MobaXterm client window, click the Tunneling icon to open the MobaSSHTunnel window.
