networking - 设置虚拟网桥 : Cannot find device "br0"

Question

在 中使用以下配置在 Ubuntu 中设置虚拟网桥/etc/network/interfaces

auto brOffline 
iface brOffline inet static
 address 192.168.5.10
 netmask 255.255.255.0
 bridge_ports eth11
 bridge_stp off
 bridge_fd 0.0
 pre-up ifdown eth11
 pre-up ifup eth11
 post-down ifdown eth11 

代码:创建桥接接口(interface)。每个网桥都需要一个适配器，这里是我的物理网卡 eth11。以确保它正在工作，使界面再次下降和上升。

导致网络服务重新启动...

service networking restart
service networking status

... 显示类似于 的错误

 ifup[2304]: Cannot find device "brOnline"
 dhclient[2330]: Error getting hardware address for "brOffline": No such device

如果您的界面被称为标准 br0 听起来像:

 default:
 Error getting hardware address for "br0": No such device

Answer 1

未安装桥实用程序

我从一个系统转移到另一个系统。目标操作系统是新安装的 17.10。缺少的是桥梁实用程序:

sudo apt-get install -y bridge-utils

由于缺少工具，根本无法创建这座桥......

现在 ifconfig展示我 Shiny 的桥

brOffline: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
    inet 192.168.5.10  netmask 255.255.255.0  broadcast 192.168.5.255
    inet6 fe80::6a05:caff:fe51:8eff  prefixlen 64  scopeid 0x20<link>
    ether 68:05:ca:51:8e:ff  txqueuelen 1000  (Ethernet)

    RX errors 0  dropped 0  overruns 0  frame 0
    TX packets 107  bytes 10316 (10.3 KB)
    TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
