change proxmox host ip post install cli

[shawzy007]

Hi there, I searched and found info but I think I am missing something

My proxmox host was intalled on ip 192.168.50.xxx and after a router change my LAN range is now 192.168.88.xxx

I need to change the IP on proxmox host so I can access it. I have followed a post and edited /etc/network/interfaces and /etc/hosts. rebooted the machine completely. The login screen shows the new IP however I can still not access it on a web browser..

Any ideas? thanks

Change the entry on /etc/hosts too and restart pve-proxy and pvecluster services (or reboot host). Details here [1]. Remember this works if host isn't in a cluster, which probable isn't as it's a single host.

try this bash script:

#!/bin/bash

# Verifica si se ejecuta como root
if [[ $EUID -ne 0 ]]; then
  echo "Este script debe ejecutarse como root"
  exit 1
fi

# Pedir la nueva IP y gateway
read -p "Nueva IP (ej: 192.168.1.200/24): " NUEVA_IP
read -p "Nueva Gateway (ej: 192.168.1.1): " NUEVA_GW

# Ruta al archivo de configuración
INTERFACES_FILE="/etc/network/interfaces"

# Crear backup del archivo original
cp "$INTERFACES_FILE" "${INTERFACES_FILE}.bak"

# Cambiar address y gateway usando sed
sed -i -E "s|^\s*address\s+.*|    address $NUEVA_IP|" "$INTERFACES_FILE"
sed -i -E "s|^\s*gateway\s+.*|    gateway $NUEVA_GW|" "$INTERFACES_FILE"

# Mostrar cambios realizados
echo "Cambio realizado!. Los nuevos valores son:"
grep -E 'address|gateway' "$INTERFACES_FILE"

# Confirmar antes de reiniciar
read -p "¿Reiniciar el servidor ahora? [s/N]: " CONFIRM

if [[ "$CONFIRM" =~ ^[sS]$ ]]; then
  echo "Reiniciando el servidor..."
  reboot
else
  echo "Reinicio cancelado. Cambios aplicados, pero se requiere reinicio para que tengan efecto."
fi

try this bash script:

That script doesn't change the IP on any of the needed files, just on the network configuration and doesn't really add anything to what you can do by hand or via webUI. Don't use it.

Show the output of ip a from the Proxmox host.
