Check All Addresses on Proxmox Servers

Server IP Addresses

• ML110 (pve): 192.168.1.207
• R630 (pve2): 192.168.1.55

Manual Check Commands

On ML110 (pve) - SSH: root@192.168.1.207

# Check hostname
hostname

# Check all IP addresses
ip addr show

# Check bridges only
ip link show type bridge
ip addr show | grep -A 5 vmbr

# Check routing
ip route show
ip route show default

# Check physical interfaces
ls -la /sys/class/net/ | grep -E "nic|eth|enp"
ip link show | grep -E "^[0-9]+: (nic|eth|enp)"

# Check current network config
cat /etc/network/interfaces

# Summary of all IPs
for iface in $(ip link show | grep -oE '^[0-9]+: [^:]+' | cut -d: -f2 | grep -v lo); do
    IP=$(ip addr show $iface 2>/dev/null | grep "inet " | awk '{print $2}')
    if [ -n "$IP" ]; then
        echo "$iface: $IP"
    fi
done

On R630 (pve2) - SSH: root@192.168.1.55

Quick Summary Commands

Get All IPs on ML110

ssh root@192.168.1.207 "ip addr show | grep 'inet '"

Get All IPs on R630

ssh root@192.168.1.55 "ip addr show | grep 'inet '"

Check Both Servers

echo "=== ML110 (pve) - 192.168.1.207 ==="
ssh root@192.168.1.207 "hostname && echo '' && ip addr show | grep -E '^[0-9]+:|inet '"

echo ""
echo "=== R630 (pve2) - 192.168.1.55 ==="
ssh root@192.168.1.55 "hostname && echo '' && ip addr show | grep -E '^[0-9]+:|inet '"

Expected Configuration

ML110 (pve) - 192.168.1.207

Expected:

• vmbr0: 192.168.1.207/24 (LAN)
• vmbr1: Public IP (WAN from Spectrum)
• Default route via vmbr1

R630 (pve2) - 192.168.1.55

Expected:

• vmbr0 (nic3): 192.168.1.55/24 (LAN)
• vmbr1 (nic2): Public IP (WAN from Spectrum)
• Default route via vmbr1

Create Address Summary Script

If you want to create a script on each server:

# On each server, create /root/check-addresses.sh
cat > /root/check-addresses.sh << 'EOF'
#!/bin/bash
echo "=== Network Address Summary ==="
echo ""
echo "Hostname: $(hostname)"
echo ""
echo "All IP Addresses:"
ip addr show | grep -E '^[0-9]+:|inet ' | grep -v '127.0.0.1'
echo ""
echo "Bridges:"
ip link show type bridge 2>/dev/null | grep -oP '^\d+: \K[^:]+' | while read br; do
    IP=$(ip addr show $br 2>/dev/null | grep 'inet ' | awk '{print $2}' | head -1)
    echo "  $br: ${IP:-No IP}"
done
echo ""
echo "Physical Interfaces:"
ls -d /sys/class/net/nic* /sys/class/net/eth* 2>/dev/null | xargs -n1 basename | while read iface; do
    STATUS=$(ip link show $iface 2>/dev/null | grep -oP 'state \K[^ ]+' || echo 'unknown')
    IP=$(ip addr show $iface 2>/dev/null | grep 'inet ' | awk '{print $2}' | head -1)
    echo "  $iface: $STATUS - ${IP:-No IP}"
done
echo ""
echo "Routing:"
ip route show | head -5
EOF

chmod +x /root/check-addresses.sh

# Run it
