通过批处理文件来监视你的服务器

　　昨天在微软的网站上看到了一个命令行方式下的端口扫描工具，down下来看了看，(你也可以到http://www.sometips.com/soft/portqry.exe下载)觉得这玩艺就操作性而言比其他同类产品差得太多，仔细一瞧，突然它居然有一个返回值的功能，这样岂不是可以在批处理文件里面来使用，呵呵，于是乎就写了个小小的脚本，希望能对大家有所帮助.

　　C:\scripts>type monitor.cmd

　　@echo off

　　setlocal

　　if {%1}=={} goto noparms

　　if {%2}=={} goto noparms

　　REM Please copy portqry.exe to the same folder with monitor.cmd.

　　portqry -n %1 -e %2 -q

　　IF %ERRORLEVEL% EQU 1 goto down

　　IF %ERRORLEVEL% EQU 0 goto up

　　:noparms

　　echo Usage: monitor.cmd ServerIP PortNumber

　　goto end

　　:up

　　echo The %2 port is listening on %1...

　　goto end

　　:down

　　echo The %2 port is not listening on %1...

　　goto end

　　:end

　　执行该脚本的结果：

　　C:\scripts>monitor.cmd

　　Usage: monitor.cmd ServerIP PortNumber

　　C:\scripts>monitor.cmd bbs.nsfocus.com 80

　　The 80 port is listening on bbs.nsfocus.com...

　　C:\scripts>monitor.cmd bbs.nsfocus.com 79

　　The 79 port is not listening on bbs.nsfocus.com...

　　你可以根据你自己的需要对这个脚本进行改动，Hope it helps...

　　附上PortQry的用法：

　　PortQry Usage:

　　PortQry.exe -n server [-p protocol] [-e || -r || -o endpoint(s)]

　　[-l logfile] [-s] [-q]

　　Where:

　　-n [server] IP address or name of server to query

　　-p [protocol] TCP or UDP or BOTH (default is TCP)

　　-e [endpoint] single port to query (valid range: 1-65535)

　　-r [end point range] range of ports to query (start:end)

　　-o [end point order] range of ports to query in an order (x,y,z)

　　-l [logfile] name of log file to create

　　-s 'slow link delay' waits longer for UDP replies from remote systems

　　-q 'quiet' operation runs with no output

　　returns 0 if port is listening

　　returns 1 if port is not listening

　　returns 2 if port is listening or filtered

　　Notes:

　　This version runs on Windows 2000 and Windows XP

　　Defaults: TCP, port 80, no log file, slow link delay off

　　Hit Ctrl-c to terminate prematurely
