KVM设置DHCP、DNS、Gateway

添加网卡

sudo vi /etc/network/interfaces

#添加下面的配置 >>>>>>>>

auto tap0

iface tap0 inet manual

up ifconfig $IFACE 0.0.0.0 up

down ifconfig $IFACE down

tunctl_user jack

auto br0

iface br0 inet static

address 10.14.24.1

gateway 10.14.24.254    #br0的网关

netmask 255.255.255.0

bridge_ports tap0

bridge_stp off

bridge_maxwait 0

bridge_fd 0

 

KVM虚拟机的xml设置固定MAC

<mac address='52:54:00:33:a4:10'/>

 

libvirt开启DHCP，绑定IP-MAC

vim /etc/libvirt/qemu/networks/default.xml

<network>
  <name>default</name>
  <bridge name="br0"/>
  <forward/>
  <ip address="10.14.24.1" netmask="255.255.255.0">
    <dhcp>
      <range start="10.14.24.2" end="10.14.24.254"/>
      <host mac="52:54:00:33:a4:10" name="test1" ip="10.14.24.10"/>
    </dhcp>
  </ip>
</network>

具体可参见 http://libvirt.org/formatnetwork.html

vim /var/lib/libvirt/dnsmasq/default.conf

interface=br0
dhcp-range=10.14.24.2,10.14.24.254

kill dnsmasq进程后重启服务libvirt服务 service libvirt-bin restart，libvirt会自动拉起dnsmasq进程

 

dnsmasq设置DNS和Gateway

vim /var/lib/libvirt/dnsmasq/default.conf

interface=br0
dhcp-range=10.14.24.2,10.14.24.254

/usr/sbin/dnsmasq --dhcp-option=6,10.14.24.1 --dhcp-option=3,10.14.24.1 --conf-file=/var/lib/libvirt/dnsmasq/default.conf   #--dhcp-option=6是DNS，3是Gateway，具体参见dnsmasq –help dhcp

 

如此KVM虚拟机就能自动获得IP，DNS和Gateway地址

注：若设置br0网卡时的netmask 与/etc/libvirt/qemu/networks/default.xml中的netmask配置的不一致，则以设置br0网卡时的netmask为准

 

Inetsim绑定网卡

修改Inetsim配置文件，绑定到对应网卡，模拟响应相关请求

vim /etc/inetsim/inetsim.conf

#########################################
# service_bind_address
#
# IP address to bind services to
#
# Syntax: service_bind_address <IP address>
#
# Default: 127.0.0.1
#
service_bind_address 10.14.24.1

 

重启下inetsim服务即可， service inetsim restart

 

Cuckoo中Auxiliary.conf 网卡修改为br0
