Select the Security tab > Advanced > Disable inheritance > Remove all inherited permissions from this object.Īuthorize your macOS or Linux machine to connect Then navigate to the private key file in Windows Explorer, right-click and select Properties. Restrict the permissions on the private key fileįor macOS / Linux, run the following shell command, replacing the path to your private key if necessary: chmod 400 ~/.ssh/id_ed25519įor Windows, run the following command in PowerShell to grant explicit read access to your username: icacls "privateKeyPath" /grant :R Tip: Don't have ssh-keygen? Install a supported SSH client. If you do not have a key, run the following command in a local terminal / PowerShell to generate an SSH key pair: ssh-keygen -t rsa -b 4096 ssh directory in your user profile folder on Windows (for example C:\Users\your-user\.ssh\id_ed25519.pub). This is typically located at ~/.ssh/id_ed25519.pub on macOS / Linux, and the. First we'll create a key pair and then copy the public key to the host.Ĭheck to see if you already have an SSH key on your local machine. To set up SSH key based authentication for your remote host. Tip: PuTTY for Windows is not a supported client, but you can convert your PuTTYGen keys. ![]() This section will walk you through how to generate these keys and add them to a host. SSH public key authentication is a convenient, high security authentication method that combines a local "private" key with a "public" key that you associate with your user account on an SSH host. This section includes some tips and tricks for getting the Remote - SSH extension up and running in different environments. SSH is powerful and flexible, but this also adds some setup complexity. Or try the introductory Tutorials to help get you running quickly in a remote environment.įor tips and questions about GitHub Codespaces, see the GitHub Codespaces documentation. See the SSH, Containers, and WSL articles for details on setting up and working with each specific extension. This article covers troubleshooting tips and tricks for each of the Visual Studio Code Remote Development extensions. Configure IntelliSense for cross-compiling.We also highly recommend checking out the step-by-step SSH tutorial. To get started with using SSH in VS Code, you'll need to download the Remote - SSH extension from the Extension Marketplace.Ĭheck out the following video to see an example of using Remote - SSH in action:Īs demonstrated above, we can SSH into a more powerful virtual machine to greatly speed up the execution time of our programs. In the classroom, you might SSH into lab machines to access computers with certain dependencies required for an assignment (like a specific version of Python or a C++ compiler), a different operating system than your own, or source code or automatic tests pre-loaded from your professor. For instance, they could have a different operating system, different tools installed, or much stronger computing power. You could connect to remote machines very different than your local machine. You can also take advantage of any tools or dependencies installed on that remote machine. If you have an app located on a different computer, you could use SSH to connect to it and access your app, view its files, and even modify, run, and debug it. You can connect over SSH into another machine from Visual Studio Code and interact with files and folders anywhere on that remote filesystem. SSH, or the secure shell protocol, lets you access a remote computer or virtual machine securely over a network connection.
