我了解到 WMI 无法在远程主机上创建文件,也无法通过网络连接复制文件:http:
//msdn.microsoft.com/en-us/library/windows/desktop/aa389288%28v=vs.85% 29.aspx
但是,它可以运行 cmd 进程。这是弗兰克怀特的升 C 代码,后面是他的例子:
https ://stackoverflow.com/a/8913231/1569434
InputParameters("CommandLine") = "cmd /c echo myFTPCommands > c:\ftpscript.txt"
您将需要四件事来使用以下所有 scriptlet,它们相互构建以使用 psexec 在远程主机上运行“普通”VBScript 或批处理脚本:
- 远程主机的管理员权限;
- 在远程主机上启用 WMI
- 您的远程主机可以访问的网络共享(使用 RPC、UNC、FTP 等,但不是DFS!(“分布式文件系统” - 见注释);和
- psexec.exe 和网络共享上的“正常”脚本。
重要提示:请勿使用DFS映射网络共享!如果您将分布式文件系统用于网络共享,它将失败。无论您使用哪种操作系统(例如,XP、Win 7),根据您的尝试方式,您可能会得到一个错误代码是“系统错误 1312” 。
当远程主机上的 RPC 不可用但 WMI 可用时,以下方法将在远程主机的 c:\temp 文件夹上创建一个本地 ASCII 文件,其中包含文本“myTextCommands”,不带引号。
' https://stackoverflow.com/questions/8884728/wmi-remote-process-to-copy-file
strCommand = "cmd /c echo myTextCommands > c:\temp\testscript.txt"
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
Set objProcess = objWMIService.Get("Win32_Process")
errReturn = objProcess.Create(strCommand, null, null, intProcessID)
' See following link for error codes returned by errReturn
' http://msdn.microsoft.com/en-us/library/windows/desktop/aa389388(v=vs.85).aspx
请注意上面脚本中的重要限制:它只能创建 ASCII 文件 - 而不是二进制文件。
让我们使用该技术来映射驱动器号:
strCommand = "cmd /c net use z: " & MyShare & " /user:%USERDOMAIN%\%USERNAME% " _
& strPassword & ">" & strRemoteLog
Set objProcess = objWMIService.Get("Win32_Process")
Call errProcess
其中“strRemoteLog”设置为“c:\temp\MyLog.txt”,提示“strPassword”(参见底部的完整脚本示例和参考),“errProcess”是一个子例程,使用上面提到的“cmd /c”技巧:
Sub errProcess
errReturn = objProcess.Create(strCommand, null, null, intProcessID)
If errReturn = 0 Then
Wscript.Echo "Process was started with a process ID: " & intProcessID
WScript.Sleep 5000
Else
Wscript.Echo "Process could not be started due to error: " & errReturn
End If
End Sub
映射网络驱动器后,将脚本复制到主机:
strCommand="cmd /c xcopy Z:\scripts\SCRIPT1.bat c:\temp\ >>" & strRemoteLog
Call errProcess
SCRIPT1.bat 已准备就绪,因此在远程主机上针对它启动 psexec,向您的脚本传递一个变量 strUserID,该变量将在之前获得,例如:
strCommand="cmd /c Z:\psexec \\%COMPUTERNAME% /accepteula -s -n 120 " _
& cmd /c c:\temp\SCRIPT1.bat " & strUserID & ">>" & strRemoteLog
Call errProcess
psexec 完成后,您可能希望保存结果。所以你重命名日志文件,上传它,取消映射你的驱动器,并清理残留文件:
strCommand="cmd /c REN " & strRemoteLog & " SCRIPT1-%COMPUTERNAME%.txt"
Call errProcess
strCommand="cmd /c MOVE /Y c:\temp\SCRIPT1*.txt Z:\scripts\LOGS\"
Call errProcess
strCommand="cmd /c net use * /del /Y"
Call errProcess
strCommand="cmd /c del c:\temp\SCRIPT1*.bat /q"
Call errProcess
你完成了。您已成功映射驱动器、针对远程主机运行例程脚本并上传其输出。
请注意,此方法也适用于带有 UAC 的 Windows 7 和 Windows 2008。
这是完整的“示例”集成脚本。随时提出修复、改进等建议。
