# 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
|
|
|
|
```bash
|
|
# 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

|
|

|
|
fi
|
|

|
|
## Quick Summary Commands
|
|
|
|
### Get All IPs on ML110
|
|
|
|
```bash
|
|
ssh root@192.168.1.207 "ip addr show | grep 'inet '"
|
|
```
|
|
|
|
### Get All IPs on R630
|
|
|
|
```bash
|
|
ssh root@192.168.1.55 "ip addr show | grep 'inet '"
|
|
```
|
|
|
|
### Check Both Servers
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
# 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
|
|
/root/check-addresses.sh
|
|
```
