Python：检查网络接口是否已启动 [英] Python: check whether a network interface is up

问题描述

在Python中，有没有办法检测给定的网络接口是向上？

In Python, is there a way to detect whether a given network interface is up?

In我的脚本，用户指定一个网络接口，但我想确保接口已启动，并且在执行任何其他操作之前已经分配了IP地址。

In my script, the user specifies a network interface, but I would like to make sure that the interface is up and has been assigned an IP address, before doing anything else.

我在 Linux ，我 root 。

推荐答案

As由@Gabriel Samfira建议，我使用 netifaces 。当IP地址与给定接口关联时，以下函数返回True。

As suggested by @Gabriel Samfira, I used netifaces. The following function returns True when an IP address is associated to a given interface.

def is_interface_up(interface):
    addr = netifaces.ifaddresses(interface)
    return netifaces.AF_INET in addr
