Powershell使RemoteDrive会话保持打开状态

最小问题：

执行以下操作后，如何正确处理留下的远程会话连接：

$session = New-PSSession -ComputerName $VM -Credential $CurrentUser
Invoke-Command -Session $session -ScriptBlock {
    $drive = New-PSDrive -Credential $Using:CurrentUser "dummyDriveName" -Root (Split-Path $Using:TargetPath) -PSProvider "FileSystem" 
    Set-Location $Using:TargetPath
}

Invoke-Command -Session $session -ScriptBlock {
    Remove-PSDrive "dummyDriveName"
}
Remove-PSSession -Session $session

---

我运行的代码大致如下所示：

$VMs = @(
    "vm1.foo.lan",
    "vm2.foo.lan",
    "vm3.foo.lan"
)

$TargetPath = "\\$env:ComputerName\bar\bin\Debug"

$CurrentUser = (Get-Credential -Credential $env:UserName)
[System.Management.Automation.Runspaces.PSSession[]]$Sessions = @()

foreach ($VM in $VMs) {
    $session = New-PSSession -ComputerName $VM -Credential $CurrentUser
    $Sessions = $Sessions + $session

    Invoke-Command -Session $session -ScriptBlock {
        $drive = New-PSDrive -Credential $Using:CurrentUser "dummyDriveName" -Root (Split-Path $Using:TargetPath) -PSProvider "FileSystem" 
        Set-Location $Using:TargetPath
        #Actually do something here, but it's not relevant ... I can reproduce with this line commented out.
    }
}

# Wait until Target.exe are known to be complete.

foreach ($session in $Sessions) {
    Invoke-Command -Session $session -ScriptBlock {
        Remove-PSDrive "dummyDriveName"
    }
    Remove-PSSession -Session $session
}

foreach ($session in $Sessions) {
    Write-Host ""
    $vmName = $session.ComputerName
    $vmIPAddress = [System.Net.Dns]::GetHostAddresses($vmName).IPAddressToString

    Write-Host "*** Killing any active Target.exe processes on $vmName ***"
    Invoke-Command -Session $session -ScriptBlock {
        Stop-Process -Name "Target" -Force
    }

    Write-Host "*** Disconnecting the remote Drive created to give $vmName easy access to $RepositoryShare***"
    Invoke-Command -Session $session -ScriptBlock {
        Remove-PSDrive "dummyDriveName" 
    }

    Write-Host "*** Closing any open PS connections to $vmName ***"
    Remove-PSSession -Session $session

    Write-Host "*** Closing the still-open Windows Share connection from $vmName to $env.ComputerName ***"
    Get-SmbSession | Where-Object {$_.ClientComputerName -eq $vmIPAddress} | Close-SmbSession -Force
}

我的目的是让一组远程机器都调用我机器上的

exe

，通过远程共享公开

广义而言，我：

• 以我自己的身份连接到远程机器
• 捕捉这种联系
• 设置一个连接到我的远程驱动器
  • （这是为了避免双跳问题而不诉诸于

    CredSsp

    请参见：）
• 做点什么
• 对所有机器重复上述步骤
• 等待远程进程完成
• 重新连接到所有机器以卸下驱动器和连接会话

在此结束时，我仍然有：

这些会话最终似乎会衰减，但不可靠，并且会使允许的最大会话饱和，从而导致错误，如：

No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept
+ CategoryInfo          : InvalidOperation: (dummy:PSDriveInfo) [New-PSDrive], Win32Exception
+ FullyQualifiedErrorId : CouldNotMapNetworkDrive,Microsoft.PowerShell.Commands.NewPSDriveCommand
+ PSComputerName        : build7.foo.lan

更新：

感谢@jrider，他建议

获取SmbSession

。 在脚本的其余部分返回后运行：

PS C:\WorkingDirectoty> Get-SmbSession

SessionId    ClientComputerName ClientUserName NumOpens
---------    ------------------ -------------- --------
773228331225 10.xxx.yyy.89       FOO\MDM        785
773228331233 10.xxx.yyy.60       FOO\MDM        637
773228331245 10.xxx.yyy.89       FOO\MDM        239
773228331253 10.xxx.yyy.54       FOO\MDM        136
773228331261 10.xxx.yyy.54       FOO\MDM        882
773228331269 10.xxx.yyy.60       FOO\MDM        389

很明显，我不想让这个脚本盲目地关闭每个会话，不管它是否与这个脚本相关，所以我想我想把我的会话映射到IP地址，然后关闭任何有这个IP地址的会话？

有人知道实现这一点所需的PowerShell咒语吗？

按计算机名关闭SMB会话（更新以包括Brondahl的建议）：

作为最终参考，我的完整清理代码如下所示：

$VMs = @(
    "vm1.foo.lan",
    "vm2.foo.lan",
    "vm3.foo.lan"
)

$TargetPath = "\\$env:ComputerName\bar\bin\Debug"

$CurrentUser = (Get-Credential -Credential $env:UserName)
[System.Management.Automation.Runspaces.PSSession[]]$Sessions = @()

foreach ($VM in $VMs) {
    $session = New-PSSession -ComputerName $VM -Credential $CurrentUser
    $Sessions = $Sessions + $session

    Invoke-Command -Session $session -ScriptBlock {
        $drive = New-PSDrive -Credential $Using:CurrentUser "dummyDriveName" -Root (Split-Path $Using:TargetPath) -PSProvider "FileSystem" 
        Set-Location $Using:TargetPath
        #Actually do something here, but it's not relevant ... I can reproduce with this line commented out.
    }
}

# Wait until Target.exe are known to be complete.

foreach ($session in $Sessions) {
    Invoke-Command -Session $session -ScriptBlock {
        Remove-PSDrive "dummyDriveName"
    }
    Remove-PSSession -Session $session
}

foreach ($session in $Sessions) {
    Write-Host ""
    $vmName = $session.ComputerName
    $vmIPAddress = [System.Net.Dns]::GetHostAddresses($vmName).IPAddressToString

    Write-Host "*** Killing any active Target.exe processes on $vmName ***"
    Invoke-Command -Session $session -ScriptBlock {
        Stop-Process -Name "Target" -Force
    }

    Write-Host "*** Disconnecting the remote Drive created to give $vmName easy access to $RepositoryShare***"
    Invoke-Command -Session $session -ScriptBlock {
        Remove-PSDrive "dummyDriveName" 
    }

    Write-Host "*** Closing any open PS connections to $vmName ***"
    Remove-PSSession -Session $session

    Write-Host "*** Closing the still-open Windows Share connection from $vmName to $env.ComputerName ***"
    Get-SmbSession | Where-Object {$_.ClientComputerName -eq $vmIPAddress} | Close-SmbSession -Force
}

您是否可以使用

Copy Item-ToSession

将exe复制到远程计算机并从那里运行（如有必要，随后删除）？无需重新连接等。对于您的问题，“我如何正确地处理完成后留下的远程会话连接…”您已经知道了

Remove-PSSession

@lordam显然不是，因为这样做之后这些会话仍然存在@boxdog的想法不错，但不幸的是，由于目标的性质，它不是一个选项。exe@Brondahl在删除之前，您是否尝试过使用

退出PSSession

？不知道这是否会造成不同您是否可以添加

[System.Net.Dns]：：GetHostAddresses（$vmName）.IPAddressToString
