取消 NetworkManager 管理
桌面版本的 Linux 系统大多使用 NetworkManager 管理网络，在网络抓包时，我们的临时修改会被重置，为了避免干扰，应当将抓包网卡从 NetworkManager 中移除。
nmcli 命令行工具可以控制 NetworkManager 并显示网络状态，在本文将用于管理接口。
显示接口状态
nmcli device status
接口状态呈现
enp0s3 ethernet connected Wired connection 1
lxcbr0 bridge connected (externally) lxcbr0
lo loopback unmanaged --
接口接管管理
nmcli device set lxcbr0 managed no # 将 lxcbr0 移除管理
nmcli device set lxcbr0 managed yes # 将 lxcbr0 加入管理
关闭系统 wpa_supplicant 和 hostapd
The sudo systemctl disable wpa_supplicant + sudo systemctl stop wpa_supplicant will ONLY temporarily disable wpa_supplicant service until the network manager restarts and/or the system reboots.
So, to correctly and/or completely disable the wpa_supplicant service from running again in the future even after the network manager restarts and/or the system reboots is to mask the service, i.e.
systemctl mask wpa_supplicant.service
etc., as pointed out in this article. This will create a symbolic file
/etc/systemd/system/wpa_supplicant.service → /dev/null
