讓 service 呼叫有作用

修改 /etc/default/hostapd

加入

DAEMON_CONF="/etc/hostapd/hostapd.conf"

debug

sudo hostapd /etc/hostapd/hostapd.conf

start

sudo service hostapd start

目前完成第一版 script

ap_mode:
        sudo cp interfaces_ap /etc/network/interfaces
        sudo cp hostapd /etc/default/hostapd
        # sudo service hostapd restart
        # sudo /etc/init.d/networking restart
        sudo reboot

client_mode:
        # sudo service hostapd stop
        sudo rm /etc/default/hostapd
        sudo cp interfaces_client /etc/network/interfaces
        # sudo /etc/init.d/networking restart
        sudo reboot

相關檔案如上述，用 reboot 方式，若用 hot reload 的方式異常比較多

smlsunxie commented 8 years ago

不用 reboot 就可以切換 mode

ap_mode:
        sudo ifdown wlan0
        sudo cp interfaces_ap /etc/network/interfaces
        sudo cp hostapd /etc/default/hostapd
        sudo cp udhcpd_ap /etc/default/udhcpd
        sudo service hostapd restart
        sudo service udhcpd start
        sudo ifup wlan0

client_mode:
        sudo service hostapd stop
        sudo service udhcpd stop
        sudo ifdown wlan0
        sudo rm /etc/default/hostapd
        sudo cp udhcpd_client /etc/default/udhcpd
        sudo cp interfaces_client /etc/network/interfaces
        sudo /etc/init.d/networking restart
        sudo ifup wlan0

要再加上 update-rc.d 讓 service 預設開機不啟動, 這樣重新開機後才會維持 client_mode;;; ap_mode 則相反預設啟動

client_mode:
    update-rc.d -f hostapd remove
    update-rc.d -f udhcpd remove

然後通常需要 root 權限時，慣例是 Makefile 裡面不用 sudo，在執行 make 指令依照狀況 + sudo

sudo make client_mode
