8/16/2023 0 Comments Visual studio code ssh remote![]() ![]() To connect to a compute node, however, setting up our SSH keys appropriately is a necessary step. We’ve not yet made explicit use of these keys and instead used password-based authentication. A key feature is its use of cryptographic keys to authenticate users for access to the remote server. It is a widely used tool that provides users with a secure channel to a remote host. When your connecting to the computing cluster in the above manner, you are using the Secure Shell (SSH) protocol. ![]() For now, enter your password and wait for VS Code to establish the remote connection. The next section illustrates how this can be avoided in the future. Once the config file is updated, open a remote window by selecting “Connect to Host…” and selecting the desired server from the dropdown menu.Īt this point, VS Code is likely asking for a password before admitting you to the cluster. See the below snippet for the entries in my file for the Mercury and Acropolis computing clusters at UChicago. This will open a config file where you can specify the address of the computing cluster ( HostName) as well as your username ( User) and store them under a convenient name ( Host). gif), where you should select “Open SSH Configuration File…”. Clicking on it opens a dropdown menu (see the. Once the extension is installed, the bottom-left of your VS Code application will show a green box (“Open a Remote Window”). The Remote-SSH extension allows you to connect to a computing server directly from your local machine. You can do so directly within VS Code: Use the top-menu bar and navigate to File->Preferences->Extensions (or use Ctrl+Shift+X). Next, install the VS Code extension Remote-SSH. To get started, download and install the appropriate version of VS Code for your system. Connecting directly to the compute node with VS Code.Įxamples focus on the Mercury and Acropolis computing clusters based at the University of Chicago, but the tutorial should be broadly applicable to many university computing servers.Initializing a compute node with the desired resources and.Setting up SSH keys on the computing cluster.Setting up VS Code and the SSH-Remote extension.The four steps discussed in this post are: The following is meant as a guide for the setup process and for establishing your first remote connection. The best part about it? It’s super easy once set up! Most importantly, it lets you develop using the convenience of your local machine but leveraging the superior computation resources of the computing cluster (i.e., far more memory, CPU cores, and/or a GPU). This post outlines how to set up Visual Studio Code (VS Code) for interactive development on a compute node (i.e., not the head node) of a computing cluster. ![]()
