Beaglebone black eth0 获取不到静态ip配置

Question

我有一个接口 eth0，我将其添加到网桥 (br-lan)。

然后我想把eth0的IP给br-lan，让eth0进入没有IP的状态。

我执行了以下步骤，但在一段时间后 eth0 获得了另一个不同于 br-lan 但在同一子网内的 DHCP IP。

# brctl addbr br-lan
# brctl addif br-lan eth0
# ifconfig br-lan up
# ifconfig

有谁知道为什么 eth0 会返回不同的 IP？

我的 /etc/network/interfaces 没有配置 eth0 DHCP。事实上，即使我向其中添加以下行，eth0 在我执行 "dhclient br-lan"

后仍会获得 192.168.11.X IP

 auto eth0
 iface eth0 inet static
   address 192.168.0.102
   netmask 255.255.255.0
  network 192.168.0.0
  gateway 192.168.0.1

我如何让 eth0 通过网络获取 DHCP IP 并坚持使用无 IP

我是运行 Beaglebone 上的 Debian 7.4

Answer 1

显然 wicd 正在重新连接 eth0。以下步骤解决了自动重新连接 eth0

的问题

将/etc/wicd/manager-settings.conf
/etc/init.d/wicd重启
