Use Port Forwarding for the Test VPS Networkingīy default port 22 is used for SSH, see a list of TCP and UDP port numbers in Wikipedia. Then on the local VM install the same OS as the one running on the live VPS. This article uses VirtualBox to configure a VM as a test VPS.Ī VPS running in the cloud can be replicated on a local machine using a VM. VirtualBox is a free application that can run VMs. Using a VM is a good way to test a system without impacting a local machine. The test environment should be the same as the live systems so that changes have the same affect when deployed. However, the chance of errors occurring is reduced. Of course there is no guarantee that the changes to the live system will not cause problems. When happy with the changes deploy to the live system with confidence. Use the test environment to try out new configurations and software. Replicate the live system in a test environment. This tutorial and guide shows how to set up a VirtualBox VM and access it via the SSH client PuTTY, replicating production world VPS access. This test configuration should accurately reflect the live VPS, reducing mistakes when moving from test to production. A deployed VPS can usually be accessed using SSH, therefore using SSH into VPS running on a VM is good practice for a live situation. This VM VPS can then be used to test configuration and software changes before deployment to a live VPS. In order to use the Terminal to create instances, set up triton and CloudAPI as well as the triton-docker commandline tool.This article discusses setting up a virtual machine (VM) as a virtual private server (VPS) and accessing it using secure shell (SSH). Right in the portal, you can easily create Docker containers, infrastructure containers, and hardware virtual machines. The public key was not entered correctly in your Triton account.The private key on your Macintosh ( id_rsa) does not match the public key stored with your Triton Compute Service account.You did not enter the correct passphrase.You may see a password prompt like this: $ ssh password: It will now appear in your table of keys under SSH. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys. In the Key Name field, provide a name for the key.Choose to Import Public Key and paste your SSH key into the Public Key field.After you copy the SSH key to the clipboard, return to your account page.Now you must import the copied SSH key to the portal. You can save this key to the clipboard by running this: pbcopy < ~/.ssh/id_rsa.pub Importing your SSH key Your public key is saved to the id_rsa.pub file and is the key you upload to your Triton Compute Service account. Never share your private key with anyone! ssh directory and is used to verify the public key you use belongs to the same Triton Compute Service account. Your private key is saved to the id_rsa file in the. Your identification has been saved in /Users/myname/.ssh/id_rsa. You will need to enter the passphrase a second time to continue.Īfter you confirm the passphrase, the system generates the key pair. You can also hit the ENTER key to accept the default (no passphrase). The ssh-keygen utility prompts you for a passphrase. Press the ENTER key to accept the default location. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key. To generate SSH keys in macOS, follow these steps:Įnter the following command in the Terminal window. When you generate the keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your instances. The other file is a public key which allows you to log into the containers and VMs you provision. One is the private key, which should never be shared with anyone. Generating an SSH keyĪn SSH key consists of a pair of files. The Terminal window opens with the commandline prompt displaying the name of your machine and your username.
