## Summary

| Status | Count | VMIDs |
|--------|-------|-------|
| ✅ Working (Chain 138) | 1/12 | 2500 |
| ⚠️  Host not authorized | 3/12 | 2400, 2501, 2502 |
| ❌ Not responding | 8/12 | 2401, 2402, 2503-2508 |

## Detailed Results

### ✅ Working (1 node)

**VMID 2500** (192.168.11.250)
- ✅ Chain ID: 138
- ✅ Block Number: 0x89de6 (564,646 in decimal)
- ✅ RPC responding correctly
- ✅ Service status: active

### ⚠️  Host Not Authorized (3 nodes)

These nodes are running but have RPC host allowlist restrictions configured:

- **VMID 2400** (192.168.11.240): Service active, RPC host allowlist configured
- **VMID 2501** (192.168.11.251): Service active, RPC host allowlist configured  
- **VMID 2502** (192.168.11.252): Service active, RPC host allowlist configured

**Note**: These nodes are functioning but require proper Host header or host allowlist configuration to accept external connections. They respond correctly from localhost.

### ❌ Not Responding (8 nodes)

These nodes are either starting up or have configuration issues:

- **VMID 2401** (192.168.11.241): Service activating
- **VMID 2402** (192.168.11.242): Service active but RPC not responding
- **VMID 2503** (192.168.11.253): Service active but RPC not responding
- **VMID 2504** (192.168.11.254): Service activating
- **VMID 2505** (192.168.11.201): Service activating
- **VMID 2506** (192.168.11.202): Service activating
- **VMID 2507** (192.168.11.203): Service activating
- **VMID 2508** (192.168.11.204): Service active but RPC not responding

## Test Results

### VMID 2500 (Working Example)

```bash
# Chain ID
curl -X POST -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"net_version","params":[],"id":1}' \
  http://192.168.11.250:8545
# Response: {"jsonrpc":"2.0","id":1,"result":"138"}

# Block Number
curl -X POST -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
  http://192.168.11.250:8545
# Response: {"jsonrpc":"2.0","id":1,"result":"0x89de6"}
```

### VMID 2400, 2501, 2502 (Host Not Authorized)

```bash
# Response: {"message":"Host not authorized."}
```

This indicates RPC host allowlist is configured and needs to be updated or Host header needs to match allowed hosts.

## Recommendations

1. **Host Allowlist Nodes** (2400, 2501, 2502):
   - Review RPC host allowlist configuration if external access is needed
   - Check `rpc-http-host-allowlist` setting in Besu config files
   - Update allowlist or remove restriction if external access is required

2. **Non-Responding Nodes** (2401, 2402, 2503-2508):
   - Check service logs: `journalctl -u besu-rpc -f`
   - Verify configuration files are correct
   - Ensure services have completed startup (some are still activating)
   - Check for port binding issues or configuration errors
