检查本机端口

自己写的一个批处理作为nagios的插件来应用，用来检查业务是否正常运行（通过查看本机端口来判断），此脚本过滤了外部链接里的端口，记录下来，方便以后查找，：）

rem        ### Check Port 8022 ###
rem        首先找出含有":8022"的所有条目，包括本机监听和外部连接，然后循环进行下面的检测.
netstat -na | findstr /C:":8022" > port.txt
for /F "tokens=2 usebackq" %%j in (port.txt) do (
rem        检查本机的监听端口中含有:80端口
echo %%j | findstr /C:":8022" >null
rem        如果有80端口,则跳转到ok_8022
IF !ERRORLEVEL!==0 goto ok_8022
)
rem        如果循环完成，仍然没有8022端口，则执行下面的跳转
