当我在 Mac 上执行 ifconfig 时,我得到了以下接口的列表:
lo0
gif0
stf0
en0
fw0
en1
vmnet8
vmnet1
我想知道每个接口是什么。另外,哪一个是 IP 接口?我没有看到任何地方有 eth0,我认为这是 Linux 系统使用的标准接口名称。
答案1
我想知道每个接口是什么。
- lo0 = 环回
- gif0 = 软件网络接口
- stf0 = 6to4 隧道接口
- en0 = 以太网 0
- fw0 = 火线
- en1 = 以太网 1
- vmnet8 = 虚拟接口
- vmnet1 = 虚拟接口
类似这样的。
另外,以下哪一个是 IP 接口?
很多年前就已经不再有“那个” IP 接口了。全部其中可以配置并运行 IPv4 和/或 IPv6。默认使用哪个由路由表(特别是default
或条目)定义。0.0.0.0
::/0
我没有在任何地方看到 eth0,我认为这是 Linux 系统使用的标准接口名称。
Mac OS X 是 BSD,而不是 Linux。

===================
networksetup -listnetworkserviceorder
产生类似的输出,但它显示“按联系连接的顺序排列的网络服务列表”或按与系统偏好设置相同的顺序显示服务。

等设备。vmnet8

您可以通过运行以下命令查看有关设备的更多信息defaults read /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

iklier 所说的除了没有以太网端口的笔记本电脑和en1
只有一个以太网端口的 Mac 中的Wi-Fi 设备名称之外,en2
至少在一些带有两个以太网端口的 Mac Pro 中也存在这个名称。
答案3
在较旧的 Apple 便携式电脑上,en0 是以太网,en1 是机场 (WiFi)。
旧款 Mac Pro 配有以太网插孔,并且配有 en3,因为它们有两个以太网网卡和 Airport(WiFi)。
在没有以太网插孔的较新的 MacBook 中,en0 是 Airport(WiFi)。
