Question

我希望我的树莓每X分钟重新启动一次，将我的wifi加密狗网卡置于监视模式，然后重新启动嗅探脚本。同时，我需要通过以太网进行互联网连接。我从raspi-config启用了可预测的接口，并且USB加密狗开始被命名为wlx ????????????哪里????????????是mac地址。问题是，当我使用aircrack-ng将usb软件狗置于监视模式时，eth0中的inet addr消失了，并且我不再有Internet连接了。

我的第一次尝试是像这样设置crontab

@reboot sudo shutdown -r +X
@reboot sudo ifconfig wlan1 up
@reboot sudo airmon-ng start wlan1 
@reboot sudo python myScript.py

成功了。

但是随后树莓开始给无线网卡起不同的名称（wlan1表示内置无线卡，wlan0表示外部USB加密狗）。我的python脚本总是用wlan1mon嗅探，所以我不希望有此更改。因此，我从raspi-config启用了可预测的接口，并且USB加密狗开始命名为wlx????????????，其中????????????是mac地址。看来一切正常，但是当我将crontab更改为

时

@reboot sudo shutdown -r +X
@reboot sudo ifconfig wlx???????????? up
@reboot sudo airmon-ng start wlx???????????? 
@reboot sudo python myScript.py

如果我键入命令iwconfig wlx ????????????正确设置为wlan1mon，因为该接口名称太长，但我再也没有通过以太网的互联网连接，而ifconfig给我这个：

pi@raspberrypi:~ $ ifconfig

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

wlan0和wlan1mon不再存在，并且缺少以太网接口字段inet。 iwconfig而是给我这个：

pi@raspberrypi:~ $ iwconfig
enxb827eb269126 no wireless extensions 

wlan0    IEEE 802.11 ESSID:off/any
         Mode:Managed Access Point:Not-Associated
         Retry short limit:27 RTS thr:off Fragment thr:off
         Power Management:on

wlan1mon IEEE 802.11 Mode:Monitor Tx-Power=20dBm
         Retry short long limit:2 RTS thr:off Fragment thr:off
         Power Management:off

lo       no wireless extensions

重新启动后无法在所有接口上启动dhcpcd
