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。

.. code-block:: bash
    :caption: 显示接口状态

    nmcli device status


.. code-block:: bash
    :caption: 接口状态呈现

    enp0s3       ethernet  connected               Wired connection 1
    lxcbr0       bridge    connected (externally)  lxcbr0
    lo           loopback  unmanaged               --


.. code-block:: bash
    :caption: 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.

.. code-block::

    systemctl mask wpa_supplicant.service

etc., as pointed out in this article. This will create a symbolic file

.. code-block::

    /etc/systemd/system/wpa_supplicant.service → /dev/null
