我正在尝试使用 CNAME 而不是计算机名称来让 powershell remoting 与服务器配合使用。本地和远程计算机都位于同一网络和域中。
我已启用 powershell 远程处理,并且它可以很好地处理计算机名称。我已将 TrustedHosts 设置为 CNAME,并为 CNAME 添加了 SPN,但是当我发出时,Enter-PSSession CNAME
我收到以下信息:
Enter-PSSession : Connecting to remote server CNAME failed with the following
error message : WinRM cannot process the request. The following error
occurred while using Kerberos authentication: Cannot find the computer CNAME.
Verify that the computer exists on the network and that the name
provided is spelled correctly. For more information, see the
about_Remote_Troubleshooting Help topic.
执行后setspn -l COMPUTERNAME
我得到了这个:
Registered ServicePrincipalNames for CN=COMPUTERNAME,OU=SERVERS,DC=COMPANY,DC=private:
WSMAN/CNAME
WSMAN/COMPUTERNAME
WSMAN/COMPUTERNAME.local
TERMSRV/COMPUTERNAME
TERMSRV/COMPUTERNAME.local
HOST/COMPUTERNAME
HOST/COMPUTERNAME.local
要通过 CNAME 启用访问还需要什么?

我为解决这个问题所做的是为 Enter-PSSession 创建一个代理函数,以便帮我解析 CNAME。这可能不适用于你的情况,具体取决于为什么您需要使用 CNAME,但这对我来说有效。

begin
{
try {
$outBuffer = $null
if ($PSBoundParameters.TryGetValue('OutBuffer', [ref]$outBuffer))
{
$PSBoundParameters['OutBuffer'] = 1
}
$PSBoundParameters['ComputerName'] = ([System.Net.Dns]::GetHostByName($PSBoundParameters['ComputerName'])).HostName
$wrappedCmd = $ExecutionContext.InvokeCommand.GetCommand('Microsoft.PowerShell.Core\Enter-PSSession', [System.Management.Automation.CommandTypes]::Cmdlet)
$scriptCmd = {& $wrappedCmd @PSBoundParameters }
$steppablePipeline = $scriptCmd.GetSteppablePipeline($myInvocation.CommandOrigin)
$steppablePipeline.Begin($PSCmdlet)
} catch {
throw
}
}
process
{
try {
$steppablePipeline.Process($_)
} catch {
throw
}
}
end
{
try {
$steppablePipeline.End()
} catch {
throw
}
}
<#
.ForwardHelpTargetName Enter-PSSession
.ForwardHelpCategory Cmdlet
#>
}
我添加的唯一一行是:
$PSBoundParameters['ComputerName'] = ([System.Net.Dns]::GetHostByName($PSBoundParameters['ComputerName'])).HostName
这只是在调用本机 Enter-PSSession 之前在代理函数中将 CNAME 解析为 FQDN。
这使我能够通过组策略在我的 TrustedHosts 中设置 *.mydomain.local,并且我仍然可以使用“Enter-PSSession ShortName”或“Enter-PSSession CNAME”,而不必处理额外的 SPN 等。
