Python实现端口检测

一、背景：
在平时工作中有遇到端口检测，查看服务端特定端口是否对外开放，常用nmap，tcping，telnet等，同时也可以利用站长工具等web扫描端口等。
但是在使用站长工具发现：

每次只能输入一个检测的地址；
虽然可以输入多个端口，但是不能指定一个端口范围来进行批量检测；
没有批量任务记录日志等；

因避免由于局域网检测发起端网络限制而导致的端口检测异常，未使用python-nmap
想通过调用站长工具，实现

单次可多个地址或域名检测
单次可指定端口范围，批量检测
记录日志
二、代码：

2.2 代码
github地址

info.cfg代码

#address = 8.8.8.8
address = www.moguyun.com,www.51cto.com,www.anchnet.com
 
#检查的端口，如多个端口使用,隔开,端口范围使用'-'
#ports = 80,8080....
ports = 20-25,80,443,1433,1521,3306,3389,6379,8080,27017
 
#日志配置
[loginfo]
#日志目录
logdir_name = logdir
 
#日志文件名称
logfile_name = check_port.log
