用脚本启动hostapd，受到dhcpd的干扰

我正在尝试编写一个在 raspbian 上调用时启动 hostapd 的脚本，但我无法摆脱 dhcp 客户端进程：

启动hostapd.sh

echo 'stopping wpa supplicant'
systemctl stop wpa_supplicant.service
sudo dhcpcd -k wlan0
echo 'bringing interface down'
ifdown wlan0
ifconfig wlan0 192.168.1.1
ifconfig wlan0 netmask 255.255.255.0
echo 'tarting hostapd'
systemctl start hostapd.service
ifup wlan0
systemctl start isc-dhcp-server.service

然而，当我运行它时，dhcp 客户端会激活并阻止所有内容：

sudo sh start-hostapd.sh
stopping wpa supplicant
dhcpcd[1181]: sending commands to master dhcpcd process
bringing interface down

如何防止 dhcpd 这样做？

答案1

不管是什么原因造成的，肯定不是 dhcp服务器这样做，只是监听请求并响应。顺便说一句，我已经在我的 wlan0 上运行hostapd多年isc-dhcp-server了 - dhcp 服务器对于 AP 来说几乎是必不可少的。

看起来您有一个 dhclient 在 wlan0 上运行。也许你有iface wlan0 inet dhcp在/etc/network/interfaces.如果是这样，请将其更改为：

iface wlan0 inet static
  address 192.168.1.1
  netmask 255.255.255.0
  broadcast 192.168.1.255

或者也许您正在运行网络管理器。从轨道上用核武器攻击它。

另外，你应该运行ifup wlan0 前开始hostapd.
