网络配置br0 brtcl

1、brctl addbr br0        如果根据第3步，那这里不用写

2、brctl addif br0 eth0    如果第3步写了，这里也不用 这时候用ssh应该会断网。。。

3、设置interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto br0
allow-hotplug br0
iface br0 inet static
    address 192.168.7.64
    netmask 255.255.255.0
    gateway 192.168.7.254
    bridge_ports eth0

# The primary network interface
# This is an autoconfigured IPv6 interface
#allow-hotplug eth0
#iface eth0 inet6 auto
#auto  eth0
#iface eth0 inet static
#    address 192.168.7.64
#    netmask 255.255.255.0
#    gateway 192.168.7.254

　　

4、ifconfig eth0 0.0.0.0   去掉eth0的设置

5、# ifconfig br0 192.168.1.1       由于已经在interfaces里设置，所以这里应该不用再设置了

6、重启网络 ok
