有人可以解释一下Mac OS X中的ifconfig输出吗？

51

在Mac上执行ifconfig时，我得到以下接口的列表：

lo0
gif0
stf0
en0
fw0
en1
vmnet8
vmnet1

我想知道每个接口是什么。另外，这些是IP接口中的哪一个？我在任何地方都看不到eth0，我认为这是linux系统使用的标准接口名称。

macos ip-address ifconfig

我想知道每个接口是什么。

lo0 =回送
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

这样的事情。

另外，这些是IP接口中的哪一个？

自多年前就没有IP接口。所有这些都可以拥有IPv4和/或IPv6配置和运行。默认一到使用由路由表中定义（尤其是default或0.0.0.0，::/0条目）。

我在任何地方都看不到eth0，我认为这是linux系统使用的标准接口名称。

Mac OS X是BSD，不是Linux。

+1好答案。另外，有时您会看到ppp0，它也用于某些VPN隧道。

另外，osx VPN客户端会创建一个utun0接口。

您可以通过运行networksetup -listallhardwareports以下命令查看某些设备的“系统偏好设置”中使用的名称：

Hardware Port: HUAWEIMobile-
Device: HUAWEIMobile-Modem
Ethernet Address: N/A

Hardware Port: Bluetooth DUN
Device: Bluetooth-Modem
Ethernet Address: N/A

Hardware Port: Ethernet
Device: en0
Ethernet Address: a8:20:66:31:95:57

Hardware Port: MBBEthernet
Device: en5
Ethernet Address: 00:1e:10:1f:00:01

Hardware Port: Wi-Fi
Device: en1
Ethernet Address: 8c:2d:aa:33:03:e9

Hardware Port: Bluetooth PAN
Device: en4
Ethernet Address: 8c:2d:aa:33:03:ea

Hardware Port: Thunderbolt 1
Device: en2
Ethernet Address: 32:00:1b:25:92:c0

Hardware Port: Thunderbolt 2
Device: en3
Ethernet Address: 32:00:1b:25:92:c1

Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: N/A

===================

networksetup -listnetworkserviceorder 会产生类似的输出，但是会显示“按连接顺序联系网络服务的列表”，或者以与“系统偏好设置”相同的顺序显示服务。

networksetup不包括VMWare使用的vmnet1和vmnet8设备。

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

除了en0在没有以太网端口的笔记本电脑中和en1在具有单个以太网端口的Mac中使用Wi-Fi的设备名称外，其他人都说得更好en2，至少在某些具有两个以太网端口的Mac Pro中也是如此。

在较旧的Apple便携式电脑上，en0是以太网，en1是Airport（WiFi）。

带有以太网插孔的较旧的Mac Pro将具有en3，并且具有两个以太网NIC和Airport（WiFi）。

在没有以太网插孔的新型MacBook中，en0是Airport（WiFi）。

vmnet＃通常由VM（Parallels / VMWare）创建
