# SSH Setup Using .env Credentials

**Last Updated**: 2024-12-19

## Current Situation

The `.env` file contains:
- ✅ **Proxmox API Tokens**: `PROXMOX_TOKEN_ML110_01` and `PROXMOX_TOKEN_R630_01`
- ✅ **Proxmox Root Password**: `PROXMOX_ROOT_PASS` (found in .env)

## Understanding the Difference

### API Tokens vs SSH Password

- **API Tokens**: Used for Proxmox API authentication (already in `.env`)
  - Format: `root@pam!token-id=token-secret`
  - Used for: API calls, automation scripts
  - **Cannot be used for SSH**

- **SSH Password**: Used for SSH authentication (needed for key setup)
  - The root user's password on Proxmox nodes
  - Used for: SSH login, `ssh-copy-id`, initial key setup
  - **Not currently in `.env`**

## Options for SSH Setup

### Option 1: Use Existing Password in .env (Already Available!)

The `.env` file already contains:
```bash
PROXMOX_ROOT_PASS=L@KERS2010
```

Scripts have been updated to use `PROXMOX_ROOT_PASS`.

Then use the automated script:
```bash
# Install sshpass (if not installed)
sudo apt-get install sshpass

# Run automated setup
./scripts/setup-ssh-with-password.sh
```

### Option 2: Manual SSH Key Copy (Interactive)

```bash
# This will prompt for password
ssh-copy-id -i ~/.ssh/sankofa_proxmox.pub root@192.168.11.10
ssh-copy-id -i ~/.ssh/sankofa_proxmox.pub root@192.168.11.11
```

### Option 3: Use Existing SSH Keys

If you already have SSH access configured:
```bash
# Test existing access
ssh root@192.168.11.10 'hostname'
ssh root@192.168.11.11 'hostname'

# If working, copy the new key
ssh root@192.168.11.10 'mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys' < ~/.ssh/sankofa_proxmox.pub
ssh root@192.168.11.11 'mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys' < ~/.ssh/sankofa_proxmox.pub
```

### Option 4: Use Proxmox Web UI

1. Log in to Proxmox Web UI: https://ml110-01.sankofa.nexus:8006
2. Go to: **Datacenter** → **Nodes** → **ML110-01** → **Shell**
3. Run commands to add SSH key:
   ```bash
   mkdir -p ~/.ssh
   chmod 700 ~/.ssh
   echo "YOUR_PUBLIC_KEY_HERE" >> ~/.ssh/authorized_keys
   chmod 600 ~/.ssh/authorized_keys
   ```
4. Repeat for R630-01

## Recommended Approach

### Step 1: Password Already in .env ✅

The `.env` file already contains `PROXMOX_ROOT_PASS`. Scripts are configured to use it.

**Security Note**: The `.env` file is in `.gitignore`, so it won't be committed. Ensure proper file permissions:
```bash
chmod 600 .env
```

### Step 2: Install sshpass (for automation)

```bash
sudo apt-get install sshpass
```

### Step 3: Run Automated Setup

```bash
./scripts/setup-ssh-with-password.sh
```

## Current .env Contents

The `.env` file currently has:
- ✅ `PROXMOX_TOKEN_ML110_01` - API token for ML110-01
- ✅ `PROXMOX_TOKEN_R630_01` - API token for R630-01
- ✅ `PROXMOX_USERNAME_ML110_01` - Username (root@pam)
- ✅ `PROXMOX_USERNAME_R630_01` - Username (root@pam)
- ✅ `PROXMOX_ROOT_PASS` - **Root password** (for SSH) ✅

## Quick Setup Commands

### Password is Already in .env ✅

```bash
# Install sshpass (if not installed)
sudo apt-get install sshpass

# Run setup (uses PROXMOX_ROOT_PASS from .env)
./scripts/setup-ssh-with-password.sh
```

### If Password is NOT Available

```bash
# Manual interactive copy (will prompt for password)
ssh-copy-id -i ~/.ssh/sankofa_proxmox.pub root@192.168.11.10
ssh-copy-id -i ~/.ssh/sankofa_proxmox.pub root@192.168.11.11

# Or use Proxmox Web UI Shell to add key manually
```

## Security Considerations

1. **Password in .env**: 
   - ✅ File is in `.gitignore` (won't be committed)
   - ⚠️ Ensure file permissions: `chmod 600 .env`
   - ⚠️ Consider using SSH keys only (no password needed after initial setup)

2. **After SSH Keys are Set Up**:
   - You can remove password from `.env` if desired
   - SSH will work with keys only
   - More secure than password authentication

## Verification

After setup, verify SSH works:

```bash
# Test ML110-01
ssh -i ~/.ssh/sankofa_proxmox root@192.168.11.10 'hostname'

# Test R630-01
ssh -i ~/.ssh/sankofa_proxmox root@192.168.11.11 'hostname'
```
