一般而言，/etc/resolv.conf 文件是个软链接，其配置比较复杂，推荐使用 resolvconf 工具进行配置。
## 桥接
```bash
# Create a new bridge and change its state to up
ip link add name <bridge name> type bridge
ip link set <bridge name> up
# To add an interface (e.g. eth0) into the bridge, its state must be up
ip link set <eth interface> up
ip link set <eth interface> master <bridge name>
# Show the existing bridges and associated interfaces
bridge -d link
# OR
brctl show
# This is how to remove an interface from a bridge
ip link set <eth interface> nomaster
ip link delete <bridge name> type bridge
```
