| ==== Using SSH keys ==== | |
| SSH public key authentication is a secure way to authenticate with an SSH host by combining a local "private" key with a "public" key associated with your user account. Once you set up the SSH keys, you will not need to enter the password for every login. If you have previously set up your SSH keys (i.e. you can login with SSH to DARWIN without having to enter your password), then you do not need to do this step unless you want to create SSH keys specifically for VSCode, otherwise proceed to [[software:vscode:darwin#connect-vscode-to-compute-node|Connect VSCode to Compute Node]]. Please only generate the SSH keys on the trusted computer. For macOS / Linux, you can run the following command in a local terminal: | |
| <code> | |
| ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519-remote-darwin | |
| export USER_AT_HOST="your-user-name@darwin.hpc.udel.edu" | |
| export PUBKEYPATH="$HOME/.ssh/id_ed25519-remote-darwin.pub" | |
| ssh-copy-id -i "$PUBKEYPATH" "$USER_AT_HOST" | |
| </code> | |
| For Windows, run the following command in a local PowerShell as administrator: | |
| <code> | |
| ssh-keygen -t ed25519 -f "$HOME\.ssh\id_ed25519-remote-darwin" | |
| $USER_AT_HOST="your-user-name@darwin.hpc.udel.edu" | |
| $PUBKEYPATH="$HOME\.ssh\id_ed25519-remote-darwin.pub" | |
| |
| $pubKey=(Get-Content "$PUBKEYPATH" | Out-String); ssh "$USER_AT_HOST" "mkdir -p ~/.ssh && chmod 700 ~/.ssh && echo '${pubKey}' >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys" | |
| |
| </code> | |
| |
| Open VSCode and run "Remote-SSH: Open Configuration File" in the Command Palette (F1). Then, select ''~/vscode-remote-ssh/config'' and add or modify a host entry as shown below: | |
| |
| <code> | |
| Host DARWIN | |
| HostName darwin.hpc.udel.edu | |
| User traine | |
| Forwardx11 no | |
| ForwardX11Trusted no | |
| RemoteCommand vscode-shell-proxy -g it_css --salloc-arg=--partition=idle --salloc-arg=--cpus-per-task=4 | |
| IdentityFile ~/.ssh/id_ed25519-remote-darwin | |
| </code> | |
| |

| Now, we can connect the VSCode to the compute node. Follow the similar steps when adding the Config file from the [[:software:vscode:darwin#setting-up-remote-connections|Setting up Remote Connections]] except step 3. Since we created the host named "DARWIN", choose it and enter the credentials for DARWIN login (or [[software:vscode:darwin#using-ssh-keys| use SSH keys]]). | Now, we can connect the VSCode to the compute node.
