# R630-04 Diagnostic Report

**Date**: 2026-01-05  
**IP Address**: 192.168.11.14  
**Status**: ⚠️ **SERVER IS POWERED ON** but not accessible

---

## Executive Summary

**Finding**: r630-04 (192.168.11.14) **IS powered on and running**, contrary to initial assumption.

The server is:
- ✅ Responding to ping (TTL=63, ~5-6ms latency)
- ✅ SSH port 22 is open and accepting connections
- ✅ Running Ubuntu Linux (OpenSSH_8.9p1 Ubuntu-3ubuntu0.13)
- ❌ **NOT in Proxmox cluster** (only ml110, r630-01, r630-02 are members)
- ❌ Proxmox web interface (port 8006) **NOT accessible**
- ❌ SSH password authentication failing (requires console/iDRAC access)

---

## Diagnostic Results

### 1. Cluster Status

**Active Cluster Members**:
- ml110 (Node ID 1)
- r630-01 (Node ID 2)
- r630-02 (Node ID 3)

**r630-04**: ❌ **NOT in cluster**

### 2. Network Connectivity

| Test | Result | Details |
|------|--------|---------|
| Ping | ✅ **SUCCESS** | TTL=63, ~5-6ms latency |
| SSH Port 22 | ✅ **OPEN** | Connection succeeded |
| Proxmox Port 8006 | ❌ **CLOSED** | Connection refused |
| ARP Entry | ⚠️ **MISSING** | No ARP entry found (unusual) |

### 3. SSH Service

**SSH Server Details**:
- **Banner**: `OpenSSH_8.9p1 Ubuntu-3ubuntu0.13` ⚠️ **CRITICAL FINDING**
- **Status**: Active and responding
- **Authentication**: Password required (publickey failed)
- **Issue**: Password `L@kers2010` does not work

**⚠️ CRITICAL DISCOVERY**: 
- Proxmox VE is **Debian-based**, NOT Ubuntu
- The Ubuntu SSH banner indicates this is **NOT the Proxmox host**
- This is likely a **VM or container** running Ubuntu, or a **different device entirely**
- **No containers/VMs found** in the cluster using IP 192.168.11.14

### 4. Proxmox Status

**Proxmox Services**:
- ❌ Web interface (port 8006): **NOT accessible**
- ❌ Cluster membership: **NOT a member**
- ❓ Proxmox services status: **Unknown** (requires console access)

---

## Root Cause Analysis

### ⚠️ CRITICAL DISCOVERY: This is NOT the Proxmox Host

**Key Finding**: The SSH banner shows `OpenSSH_8.9p1 Ubuntu-3ubuntu0.13`, but:
- **Proxmox VE is Debian-based**, not Ubuntu
- **No containers/VMs** in the cluster are configured with IP 192.168.11.14
- This means **192.168.11.14 is NOT the r630-04 Proxmox host**

### Possible Scenarios

**Scenario A: VM/Container Using the IP (Most Likely)**
- A VM or container running Ubuntu is using 192.168.11.14
- It may not be registered in Proxmox (orphaned VM)
- Or it's on a different Proxmox host not in the cluster
- Or it's a standalone Ubuntu server

**Scenario B: Different Device**
- A different physical server/device is using 192.168.11.14
- May be a misconfigured network device
- Could be a different server entirely

**Scenario C: r630-04 Running Ubuntu Instead of Proxmox**
- r630-04 may have been reinstalled with Ubuntu (not Proxmox)
- The server is running, but it's not a Proxmox host
- This would explain why it's not in the cluster

**Scenario D: IP Conflict**
- Another device has been assigned 192.168.11.14
- The actual r630-04 Proxmox host may be using a different IP
- Or r630-04 is actually powered off and something else is responding

## Recommended Actions

### Immediate Actions

1. **Access Console/iDRAC**
   - Physical console access OR
   - iDRAC remote console access
   - Verify actual server state

2. **Check Proxmox Services**
   ```bash
   # Once console access is available:
   systemctl status pve-cluster
   systemctl status pveproxy
   systemctl status pvedaemon
   systemctl status pvestatd
   ```

3. **Check Network Configuration**
   ```bash
   ip addr show
   ip route show
   cat /etc/network/interfaces
   ```

4. **Verify Proxmox Installation**
   ```bash
   dpkg -l | grep pve
   pveversion
   ```

### Password Reset (If Needed)

If password reset is required:
1. Access via console/iDRAC
2. Boot into recovery mode
3. Reset root password
4. Or use iDRAC virtual console

## Network Topology Note

**TTL=63** in ping response suggests:
- Packet is traversing at least one router/switch
- Server is on the network but may be behind a gateway
- This is normal for a server on the same subnet (TTL starts at 64, decrements to 63)

**ARP Entry Missing**:
- Unusual that ARP table doesn't show entry after successful ping
- May indicate:
  - ARP cache was cleared
  - Network switch is handling ARP differently
  - Server is on a different VLAN (unlikely given ping works)

## Comparison with Other Servers

| Server | IP | Cluster Member | Proxmox Web | SSH | Status |
|--------|-----|----------------|-------------|-----|--------|
| ml110 | 192.168.11.10 | ✅ Yes | ✅ Accessible | ✅ Working | ✅ Active |
| r630-01 | 192.168.11.11 | ✅ Yes | ✅ Accessible | ✅ Working | ✅ Active |
| r630-02 | 192.168.11.12 | ✅ Yes | ✅ Accessible | ✅ Working | ✅ Active |
| r630-04 | 192.168.11.14 | ❌ No | ❌ Not accessible | ⚠️ Password issue | ⚠️ **Powered on but services down** |

---

## Conclusion

**⚠️ CRITICAL**: **192.168.11.14 is NOT the r630-04 Proxmox host**

**Evidence**:
- SSH banner shows Ubuntu (Proxmox is Debian-based)
- No containers/VMs in cluster use this IP
- Server responds but is not a Proxmox host

**What's Actually Happening**:
- Something else (VM, container, or different device) is using 192.168.11.14
- The actual r630-04 Proxmox host may be:
  - Powered off
  - Using a different IP address
  - Not installed/running Proxmox

**Next Steps**:
1. **Verify physical r630-04 server status** (check power, console/iDRAC)
2. **Check what device is actually using 192.168.11.14** (MAC address, hostname)
3. **Find the actual r630-04 Proxmox host IP** (if it exists and is running)
4. **Resolve IP conflict** if another device is using the reserved IP
