检测到wifi网络时发出警报？

当检测到wifi（无线）网络时，有没有办法播放声音提醒我？

Answer 1

问题是，据我所知，没有特定的程序/服务/守护进程可以检查新的无线网络何时出现在无线天线的范围内/从无线天线的范围内消失（实际上有airodump-ng和其他人，但这与网络管理员发生冲突）。

或者，您可以使用iwlist工具不时扫描wifi网络 。

注意：在测试中， iwlist工具可能只适用于Atheros，Intel或Broadcom卡。

这些说法，以下脚本可以做你想要的（我把它命名为wifidetect ）：

注意：您必须使用您的用户名更改脚本用户名，并使用您的无线网卡的接口名称更改wlan0 ; 你可以使用’ls / sys / class / net’命令找到它。

不要忘记在终端中使用以下命令使脚本可执行：

 chmod +x /path/to/scripts/wifidetect 

最后，使用sudo crontab -e命令编辑root的crontab条目，方法是添加以下行：

 */1 * * * * /path/to/scripts/wifidetect 

我已经设置了每分钟的cron工作，但你可以随意改变或者你认为更好。 从这个意义上看http://en.wikipedia.org/wiki/Cron 。

Answer 2

墨鱼可能是一个很好的解决方案，但是当检测到新的连接时它不会发出任何刺激（只有当你连接或断开连接时它才会发生）

另一个解决方案是使用此命令编写脚本：

iwlist scan

其中是你的wifi网络接口，例如wlan0 。
这将显示所有可用wifi连接的列表，其中包含详细信息：地址，SSID，质量，加密……

您必须注意此命令输出的变化，并在使用beep ， cvlc或mplayer显示新网络时播放您的声音。
第一个将播放一个简单的bip，而另外两个将允许播放声音文件。
