![]() If you see an alert message window pop-up when connecting, click the Yes button in the alert message window. Next, click the Open button at the bottom of the page to open the SSH tunnel. Next, click on the IP address is the text box in order to select it, then click on the Save button to save your settings. In the Auto-login username field, enter bitnami.Ĥ.5 Session settings Navigate back to the Session section at the top of the category list. NOTE: If your domain is configured with SSL, then enter localhost:443 as the DestinationĤ.4 Data settings Navigate to the Data section under the Connection column. Enter 8888 as the Source port, and localhost:80 as the Destination, then click the Add button. Click the Browse button to specify the path to your private key file.Ĥ.3 Tunnels settings Navigate to the Tunnels section of puTTY under the SSH column. Next, click the Save button to add the IP address to your saved sessions.Ĥ.2 Auth settings Navigate to the Auth section of puTTY under the SSH column. In the Session section of the puTTY category column, paste the External IP Address of your Google Cloud Virtual Machine into the Host Name (or IP address) field and the Saved Sessions field. Scroll to the bottom of the page and click the Save button.Ĥ.1 Session settings Open the main puTTY application (it’s a separate application). Then, from your puTTY Key Generator window, copy your public key text and paste it into the SSH key text box. Scroll down to the SSH Keys section of the page and click the Show and Edit link. After opening the VM instance details page, click the edit icon at the top of the page. This will open the vm instance settings page. Configure Public Key Next, go to your Google Cloud Platform compute engine VM Instances page, and click on the instance that you are configuring. After the SSH keys have been generated, change the key comment to Bitnami, then save the private and public key files to your computer.ģ. This is the application that you will use to generate a public and private SSH key pair. Generate SSH Keys Open up the application called puTTYgen. Putty is the SSH client that we will use in this tutorial to establish the connection between our Google Cloud virtual machine and our local machine.Ģ. Download puTTY The first step in this tutorial is to download puTTY. This way you can access the service in a secure way.1. ![]() When Kibana is running on port 443 (SSL), you can forward traffic to localhost to Kibana running in the private subnet. A bastion host with port forwarding can be used with other services like the Elasticsearch service that is running in a private subnet. By using SSH with local port forwarding, all communication is private and encrypted between your computer and the private instance. In this blog we have seen how to setup a SSH tunnel to the private instance in AWS that is running a simple web server and web page. When you close the SSH session, the tunnel is shut down and no further communication with the private instance is possible. To login type make ssh and to create a tunnel on port 8080 type make tunnel. The example can be deployed with make deploy and removed with make delete. The bastion host can be used to manage the private instance. There is also a bastion host that acts as a NAT router for the private network. The example project shows how to configure a project to setup a public and private network. The connection is encrypted and all data will be sent encrypted via the tunnel to your local computer. The tunnel is bidirectional which means that the private instance can answer with a web page that will be rendered by the web browser. When a SSH tunnel is created, open a browser and open The browser will connect to the local computer, and all data to port 8080 will be forwarded from the SSH server to the private instance. To setup SSH local port forwarding from localhost:8080 to the private host :80 type: $ ssh -N -L8080::80 -i bastion.pem to the private instance We will connect to the bastion host via SSH and setup a tunnel to the private instance so that the webpage is reachable from our local computer only. The public subnet is reachable via SSH using RSA keys. The private instance can connect to a basion host in the public subnet. The private instance will host a simple webpage on port 80. We will create an EC2 instance in a private subnet that has NAT connectivity. With SSH tunnels we can access servers in AWS that do not have public network connectivity. In this blog we will use SSH to setup a SSH tunnel to the virtual network in AWS. With the KeyPair we can initiate a connection to the instance and get access to the terminal. In my last blog about AWS Secure Shell (SSH) setup with EC2 and CloudFormation we have automated creating an EC2 instance with a KeyPair.
