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 through 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 using SSH.The tunnel server can be any Unix/Linux host that:

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. If the tunnel server is compromised it is one step removed from the database server. Terminating the tunnel on a separate server has the advantage of keeping your database server inaccessible from the Internet. When you use a tunnel server, Looker connects to your database server through a separate tunnel server on a restricted network. This option may not be feasible if your database server is on a protected network that does not have direct access from the Internet. One fewer host is involved, so there are no additional machines and their associated costs.

Terminating on the database has the advantage of simplicity. Can I set up an OS-wide SSH tunnel and then configure my RDP app to connect through that tunnel It's easy to do currently on Windows and Linux (ssh userhost -p port -L local:port:destination:port) (I then RDP to local:port), I'm not sure if Chrome OS sandboxes the terminal in such a way that prevents me from doing this. When you do not use a tunnel server, Looker connects directly to your database server through an SSH tunnel over the public internet. 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. SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding TCP ports and X11 connections it can. 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.
