| ## Step 1: Set up DUO Authentication for VPN Access | |
| ### 1. Enroll in DUO (if not already done): | |
| > - Go to [case.edu/utech/duo](https://case.edu/utech/duo) and follow instructions to register your device (phone/tablet/hardward token) | |

| ### 2. Install & Configure VPN | |
| - Run the installer and complete setup | |
| - Open FortiClient and configure new connection: | |

| - **Remote Gateway**: `vpn.case.edu` | |
| - **Customize Port**: `443` | |
| - Enable "**Save Credentials**" (optional) | |
| - Click **Save** | |
| ### 3. Connect to VPN: | |
| - Enter your **CWRU Network ID** (e.g., `jxh369`) and password. | |
| - Complete **DUO two-factor authentication** when prompted (approve via phone/device) | |
| - Once connected, you'll see a confirmation message. | |

| ## Step 3: Install PuTTY (SSH Client) | |
| ### 1. Download PuTTY: | |

| - Run the installer (or use the portable version). | |
| ## 2. Open PuTTY: | |
| - Launch PuTTY from the Start Menu | |
| --- | |
| ## Step 4: Configure PuTTY for Pioneer HPC | |
| ### 1. Enter Connection Details: | |
| - **Host Name (or IP address)**: `pioneer.case.edu` | |
| - **Port**: `22` | |
| - **Connection Type**: SSH | |
| ### 2. Optional: Save Session (for future use): | |
| - Under "**Saved Sessions**", type `Pioneer HPC` and click **Save** | |
| ### 3. Click "Open" to initiate the connection | |
| --- | |
| ## Step 5: Log In via SSH | |
| ### 1. Enter Credentials: | |
| - When prompted, enter your **CWRU Network ID** (e.g., `jxh369`) | |
| - Enter your password (same as VPN/CWRU login) | |
| - Complete DUO authentication again if required | |
| ### 2. Successful Login: | |
| - You should now see the **Pioneer HPC command-line interface** | |

| ## Step 6: Disconnecting | |
| ### 1. Exit SSH Session: | |
| - Type `exit` or `logout` in the terminal | |
| ### 2. Disconnect VPN: | |
| - Close PuTTY and disconnect FortiClient VPN when done. | |

| ## Troubleshooting Tips | |
| ### VPN Fails? | |
| - Ensure DUO is set up correctly | |
| - Try reconnecting or restarting FortiClient VPN | |
| ### PuTTY Connection Refused? | |
| - Verify VPN is active (`vpn.case.edu` shows "**Connected**") | |
| - Check `pioneer.case.edu` and port `22` are correct | |
| ## DUO Not Prompting? | |
| - Ensure your device is registered in DUO | |
