我基本上想要一个Windows批处理脚本,它通过一个服务器列表,并检查每个服务器是否在线ping。 服务器列表应该是一个简单的纯文本文件,看起来像这样:
...
"Google" www.google.com
"Node1" 221.12.123.1
"Download Server" dl.myserver.com
"Login Server" login.myserver.com
...
这是一个简单的纲要,程序应该做什么:
输出应如下所示:
...
Google: online
Stackoverflow: online
Node1: online
Download Server: offline
Login server: offline
...
我只是想知道在(windows)批处理中是否可以实现这一点以及如何做到这一点。如果批量不可能,我应该使用什么编程语言?是否可以用Python编程?
如果有人可以发布代码如何执行此操作,我也非常感谢,谢谢!

@echo off
setlocal enableextensions enabledelayedexpansion
for /f usebackq^ tokens^=1^,2^ delims^=^" %%a in ("servers.txt") do (
call :isOnline %%b && set "status=online" || set "status=offline"
echo %%a : !status!
)
endlocal
exit /b
:isOnline address
setlocal enableextensions disabledelayedexpansion
:: a temporary file is needed to capture ping output for later processing
set "tempFile=%temp%\%~nx0.%random%.tmp"
:: ping the indicated address and get errorlevel
ping -w 1000 -n 4 %~1 > "%tempFile%" && set "pingError=" || set "pingError=1"
:: When pinging,
::
:: we get errorlevel = 1 when
:: ipv4 - when any packet is lost. It is necessary to check for "TTL="
:: string in the output of the ping command.
:: ipv6 - when all packet are lost.
:: we get errorlevel = 0 when
:: ipv4 - all packets received. But pinging a inactive host on the
:: same subnet result in no packet lost. It is necessary to
:: check for "TTL=" string in the output of the ping command.
:: ipv6 - at least one packet reaches the host.
::
:: +--------------+-------------+
:: | TTL= present | No TTL |
:: +-----------------------+--------------+-------------+
:: | ipv4 errorlevel 0 | OK | ERROR |
:: | errorlevel 1 | OK | ERROR |
:: +-----------------------+--------------+-------------+
:: | ipv6 errorlevel 0 | | OK |
:: | errorlevel 1 | | ERROR |
:: +-----------------------+----------------------------+
::
:: So, if TTL= is present in output, host is online. If errorlevel is 0
:: and the address is ipv6 then host is online. In the rest of the cases
:: the host is offline.
::
:: To determine the ip version, a regular expresion to match a ipv6
:: address is used with findstr. As it will be only tested in the case
:: of no errorlevel, the ip address should be present in the output of
:: ping command.
set "exitCode=1"
find "TTL=" "%tempFile%" >nul 2>nul && set "exitCode=0" || (
if not defined pingError (
findstr /r /c:" [a-f0-9:][a-f0-9]*:[a-f0-9:%%]*[a-f0-9]: " "%tempFile%" >nul 2>nul && set "exitCode=0"
)
)
:: cleanup and return errorlevel
if exist "%tempFile%" del /q "%tempFile%" >nul 2>nul
endlocal & exit /b %exitCode%

这可以在批处理中轻松完成,您只需要一些for /f
循环,echo
语句,if
语句,goto
/ call
语句并使用ping
命令。
1.将列表中所有服务器的描述列表打印到 屏幕。
您可以使用echo
语句,例如echo "Google" www.google.com
2.如果一个ping成功,应该将第一台服务器服务器ping 4次 如果所有4次ping失败则返回在线状态,它应该离线返回。
在for /f
循环内[如for /f "tokens=5 delims==, " %%p in (
],您可以使用ping
命令,其中包含4个特征ping -n 4 www.google.com
3.打印列表中第一台服务器旁边的在线或离线打印
你可以在这里使用和if
statemenet,例如:if "%status%"=="online" echo Google: online
或echo Google: %status%
4.运行列表中所有其他服务器的步骤2和3。
您可以在此处使用goto
或call
语句(将其用作函数),例如:call :server_status_function www.google.com
