linux - RTNETLINK 回答：设备或资源忙；ifup: 未能调出 wlxf4f26d13b2bd

问题描述

我正在尝试通过 /etc/network/interfaces 配置网络这是我的文件：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug usb0
iface usb0 inet dhcp

# The wifi network interface
iface wlxf4f26d13b2bd inet manual 
    hwaddress ether 2a:bf:x9:53:38:9d
    wpa-driver nl80211
    wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

但是当我尝试激活设备时，ifup wlxf4f26d13b2bd我得到：

> RTNETLINK answers: Device or resource busy ifup: failed to bring up
> wlxf4f26d13b2bd

我没有使用 NetworkManager。

这是 ifup 的详细输出：

ifup -v wlxf4f26d13b2bd

解决方案

我解决了这个问题。问题是它试图在 wpa_supplicant 配置之后更改 MAC 地址；不遵守文件中命令的顺序。简单的解决方案是pre-up macchanger -m在 iface 节内设置 mac 地址，或者在 wpa-supplicant 之前调用 macchanger。谢谢！
