Python找出9个连续的空闲端口

出现了 10.173.1.208:3210 所以 3210 端口是被占用的

对这些信息进行搜索 :5000, 如果存在, 就表示5000端口是LISTEN**.

如果输出结果中不存在 :5000 的相关字符，表示这个端口不被占用.

netstat - tnpl | grep 321
tcp 0 0 10.173.1.208:3211 0.0.0.0:* LISTEN 55563/***
tcp 0 0 0.0.0.0:3212 0.0.0.0:* LISTEN 55586/***
tcp 0 0 10.173.1.208:3213 0.0.0.0:* LISTEN 55707/***
tcp 0 0 0.0.0.0:3214 0.0.0.0:* LISTEN 54272/java
tcp 0 0 0.0.0.0:3215 0.0.0.0:* LISTEN 54272/java
tcp 0 0 10.173.1.208:3216 0.0.0.0:* LISTEN 54822/***
tcp 0 0 10.173.1.208:3217 0.0.0.0:* LISTEN 34959/***
tcp 0 0 10.173.1.208:3218 0.0.0.0:* LISTEN 54849/***

依据这个思路, 给出代码.

AIX 、HP 、WINDOWS、 LINUX、 SOLARIS 这几个平台查看端口信息的方式不同,

先进行机器平台的判断

然后调用各个平台的端口占用判断函数

如果要找出连续端口, 其中只要有一个端口占用, 就跳出循环
