我一直在尝试使用 netplan 在我的 EC2 实例(Ubuntu 20.04)上创建一个网桥,但我一直无法访问我的机器。目前正在尝试禁用 ENA,但不确定我是否只是遗漏了一些明显的东西。这似乎类似于这个问题。
我的“库存”配置如下:
network:
ethernets:
ens5:
dhcp4: true
dhcp6: false
match:
macaddress: **:**:**:**:**:**
set-name: ens5
version: 2
与ifconfig
并ip a
返回:

我尝试通过添加br0
和复制 macaddress 来进行桥接,就像他们在此处所做的那样,但之后无法重新连接到 EC2 实例。
我都试过了
network:
ethernets:
ens5:
dhcp4: false
dhcp6: false
match:
macaddress: **:**:**:**:**:**
set-name: ens5
version: 2
bridges:
br0:
dhcp4: true
macaddress: **:**:**:**:**:**
interfaces: [ens5]
就像在 netplan.io/examples 中用于桥接和在AWS dhcp 服务器周围工作一样,并且还dhcp
完全删除了这些线路,因为显然我不知道我在做什么。
非常感谢任何建议,因为我根本没有太多配置网络的经验。谢谢!
