多线程批量ping服务器

最近由于工作的需要写了个多线程批量ping服务器的脚本，如果服务器down了，自动发报警邮件(可以添加多收件人)

 

提示：程序网页显示可以能有缩进问题。

multithreading_ping_host.py 主程序使用需要一个参数，(参数：服务器IP地址列表)

send_mail.py 发邮件程序

ip.yml 服务器IP地址列表

[root@nginx1 python]# cat /root/python/ip.yml 
192.168.1.1
192.168.1.103
192.168.1.100
www.360kad.com
192.168.1.245

[root@nginx1 python]# ./multithreading_ping_host.py /root/python/ip.yml 

程序效果：

[root@nginx1 python]# cat multithreading_ping_host.py
