# Accessing CWRU Pioneer HPC System Remotely via SSH (PuTTY)
## 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)
> - This is required for FortiClient VPN authentication.
---
## Step 2: Install and Configure FortiClient VPN
### 1. Download FortiClient VPN:
- Visit [case.edu/utech/help/forticlient-vpn](https://case.edu/utech/help/forticlient-vpn)
- Download the **FortiClient VPN** software for your specific device.
### 2. Install & Configure VPN
- Run the installer and complete setup
- Open FortiClient and configure new connection:
- **Connection Name**: `CWRU VPN` (or any name)
- **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:
- If not installed, download from [https://www.putty.org](https://www.putty.org)
- 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
