我现在在这个问题上挣扎了很多时间,并且已经在另一个论坛上问过,这有助于接近解决方案,但最后我没有实现。
我“只是”需要借助 powershell 脚本来收集有关我们公司云内部主机的信息。您可以通过本地网络的 jumphost 访问云,jumphost 也是云的一部分。然后从 jumphost 你可以到达所有的 cloudhosts。所以我用 2 pssessions 尝试了这个并使用了调用命令(jumphost 和 cloudhost 的密码相同):
$cred = Get-Credential ad\username -Message "Please insert the password for the jumphost and the cloudhost"
$session = New-PSSession -ComputerName jumphost -Credential $cred
$cldhost = Read-Host "Please insert the name of the cloudhost"
$script = {
Param (
$Credential,
$cloudhost
)
$ses = New-PSSession -ComputerName $cloudhost -Credential $Credential
Invoke-Command -Session $ses -ScriptBlock { Get-ChildItem C:\ }
Remove-PSSession $ses
}
Invoke-Command -Session $session -ScriptBlock $script -ArgumentList $cred, $cldhost
Remove-PSSession $session
但这总是给我 Jumphost 的 C:\ 而不是 cloudhost 的输出。
在另一个论坛中,我被建议使用 credssp 或委派会话。CredSSP 在这里是不可能的,因为我收到了 AD 帐户中缺少 SPN 的错误,并且我不允许添加一个并且委派的会话对我没有帮助,因为我对 jumphost 和cloudhost 并且不需要委托某些东西。
但是无论如何,我认为这不是凭据的问题,因为我没有收到“拒绝访问”错误或其他错误,并且将输入 pssession 输入到 jumphost 并从那里调用命令到 cloudhost 没有问题,但我不能在脚本中使用它。嵌套 pssessions 代码的逻辑似乎有问题......
您有什么想法可以在这里正常工作吗?

非常感谢,马克
顺便说一句:我尝试使用 CredSSP,因为建议将其用于第二跳:
Enable-WSManCredSSP -Role Client -DelegateComputer jumphost -Force
$cred = Get-Credential ad\username -Message "Please insert the password for the jumphost and the cloudhost"
$session = New-PSSession -ComputerName jumphost -Credential $cred
Invoke-Command -Session $session -ScriptBlock {Enable-WSManCredSSP -Role Server –Force; Set-Item wsman:\localhost\client\trustedhosts -value localcomputer -Force; Restart-Service winrm -Force}
$session2 = new-PSSession -ComputerName jumphost -Credential $cred -Authentication Credssp
输入最后一个命令后,我收到以下错误:
The WinRM client cannot
process the request. A computer policy does not allow the delegation of the user credentials to the target computer because the
computer is not trusted. The identity of the target computer can be verified if you configure the WSMAN service to use a valid
certificate using the following command: winrm set winrm/config/service '@{CertificateThumbprint="<thumbprint>"}' Or you can
check the Event Viewer for an event that specifies that the following SPN could not be created: WSMAN/<computerFQDN>. If you find
this event, you can manually create the SPN using setspn.exe . If the SPN exists, but CredSSP cannot use Kerberos to validate
the identity of the target computer and you still want to allow the delegation of the user credentials to the target computer,
use gpedit.msc and look at the following policy: Computer Configuration -> Administrative Templates -> System -> Credentials
Delegation -> Allow Fresh Credentials with NTLM-only Server Authentication. Verify that it is enabled and configured with an SPN
appropriate for the target computer. For example, for a target computer name "myserver.domain.com", the SPN can be one of the
following: WSMAN/myserver.domain.com or WSMAN/*.domain.com. Try the request again after these changes. Weitere Informationen

我不知道如何进一步使用 CredSSP,无论如何最好在没有 CredSSP 的情况下使其工作。
另外好的:它应该与委派会话一起使用,我尝试了以下方法:
在 Jumphost 上:
Register-PSSessionConfiguration -Name PowerShell.Session -SessionType DefaultRemoteShell -AccessMode Remote -RunAsCredential 'ad\username' -ShowSecurityDescriptorUI –Force
然后授予用户“ad\username”的访问权限(调用和读取访问权限)。之后,我可以通过以下命令在 jumphost 上使用会话配置:
$cred = Get-Credential ad\username -Message "Please enter the password for jumphost"
$session = New-PSSession -ConfigurationName PowerShell.Session -ComputerName jumphost -Credential $cred
因此会话已连接,我输入了其他命令:
$cldhost = Read-Host "Please enter the cloudhost name"
$script = {
Param (
$Credential,
$Hostname2
)
$ses = New-PSSession -ComputerName $Hostname2 -Credential $Credential
Invoke-Command -Session $ses -ScriptBlock { Get-ChildItem C:\ }
Remove-PSSession $ses
}
Invoke-Command -Session $session -ScriptBlock $script -ArgumentList $cred, $cldhost
Remove-PSSession $session
不幸的是,我再次得到了 Jumphost 的 Get-ChildItem C:\ 的输出,而不是 cloudhost 的输出......你还有什么进一步的想法吗?也许 $script{} 部分有问题吗?
