#!/bin/bash

IPTABLES=/sbin/iptables

VIRT_IF="virbr0"
EXT_IF="eth0"

$IPTABLES -F INPUT
$IPTABLES -F OUTPUT
$IPTABLES -F FORWARD
$IPTABLES -t filter -F
$IPTABLES -t nat -F
$IPTABLES -t mangle -F

$IPTABLES -A FORWARD -i $VIRT_IF -o $VIRT_IF -p udp --sport 5353 --dport 5353 -j ACCEPT
$IPTABLES -A FORWARD -p igmp -j ACCEPT

Comandos utiles:

  tail -F virt-test/logs/latest/debug.log | grep "DEBUG| Could not verify DHCP lease"
  ssh $(cat virt-test/logs/latest/debug.log | grep "DEBUG| Could not verify DHCP lease" | awk '{print $10}' | tail -n 1)
