Question

我有一个接口eth0，我添加到bridge（br-lan）。

然后我想将eth0的IP提供给br-lan并将eth0带到没有IP的状态。

我做了以下步骤但是在一段时间之后，eth0获得了另一个与br-lan不同但在同一子网内的DHCP IP。

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

有没有人知道为什么eth0会找回不同的IP？

我的/ etc / network / interfaces没有配置eth0 DHCP。事实上即使我添加以下行，eth0仍然获得192.168.11.X IP＆＃34; dhclient br-lan＆＃34;

 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

如何让eth0网络获取DHCP IP并坚持使用无IP

我在Beaglebone上运行Debian 7.4

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

在/etc/wicd/manager-settings.conf中更改“auto_reconnect = True”为“auto_reconnect = False”
/etc/init.d/wicd restart

Beaglebone black eth0没有获得静态ip配置
