Prerequisites & Environment Check

• Active SSH daemon on the target Ubuntu instance (default port 22).
• Verified terminal connectivity from the Windows host (cmd or PowerShell).
• Cursor editor installed locally.

SSH Connection Routing

Define a persistent connection alias to simplify workspace linking. Open or create the local SSH client configuration file located at %USERPROFILE%\.ssh\config. Append the followign block, substituting placeholders with your actual credentials:

Host ubuntu-rust-dev
    HostName 203.0.113.45
    User deployer
    IdentityFile C:\Users\localadmin\.ssh\rust_ed25519
    ForwardAgent yes
    ServerAliveInterval 60

Verify connectivity through the Windows terminal:

ssh ubuntu-rust-dev

If the session initiates without authentication prompts, the network route and key permissions are correctly established. Terminate the session with exit.

Extension Integration

Cursor maintains full compatibility with the standard VS Code marketplace. Install the necessary bridging component by navigating to the Extensions view (Ctrl+Shift+X). Locate Remote - SSH and apply the installation button. Restart the editor if prompted.

Workspace Initialization

Trigger the connection manager via Ctrl+Shift+P. Execute the command Remote-SSH: Connect to Current Window or select Connect to Host.... Choose the ubuntu-rust-dev alias.

During the initial handshake, the remote agent downloads and installs the cursor-server binaries into ~/.vscode-server. Once the green status indicator confirms the SSH tunnel is active, open the directory containing your Cargo workspace. Local configurations stored in .vscode/settings.json will automatically propagate to the remote context.

Rust Toolchain Synchronization

Ensure the target environment contains the necessary compilation utilities. Execute the bootstrap script to establish the stable toolchain:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"

Integrate the Language Server Protocol implementation for intelligent code navigation:

rustup component add rust-src rust-analyzer

Cursor detects the remote rust-analyzer executable automatically upon folder opening. Adjusting language-specific settings within the IDE will route requests through the SSH channel.

Environment Validation

Confirm functionality by creating a temporary entry point and inspecting auotcompletion responses.

1. Generate src/main.rs within the remote explorer.
2. Type fn compute() and observe signature suggestions.
3. Launch an integrated terminal and execute cargo check --all-targets.
4. Verify zero diagnostics and successful binary generation.

Diagnostic Reference

Proceed with incremental feature additions once the base pipeline demonstrates stable code analysis and execution metrics.
