Instruction to allow WinRM connection

#!powershell #Requires -Version 3.0 # Configure a Windows host for remote management with Ansible # ----------------------------------------------------------- # # This script checks the current WinRM (PS Remoting) configuration and makes # the necessary changes to allow Ansible to connect, authenticate and # execute PowerShell commands. # # All events are logged to the Windows EventLog, useful for unattended runs. # # Use option -Verbose in order to see the verbose output messages. # # Use option -CertValidityDays to specify how long this certificate is valid # starting from today. So you would specify -CertValidityDays 3650 to get # a 10-year valid certificate. # # Use option -ForceNewSSLCert if the system has been SysPreped and a new # SSL Certificate must be forced on the WinRM Listener when re-running this # script. This is necessary when a new SID and CN name is created. # # Use option -EnableCredSSP to enable CredSSP as an authentication option. # # Use option -DisableBasicAuth to disable basic authentication. # # Use option -SkipNetworkProfileCheck to skip the network profile check. # Without specifying this the script will only run if the device's interfaces # are in DOMAIN or PRIVATE zones. Provide this switch if you want to enable # WinRM on a device with an interface in PUBLIC zone. # # Use option -SubjectName to specify the CN name of the certificate. This # defaults to the system's hostname and generally should not be specified. # Written by Trond Hindenes <trond@hindenes.com> # Updated by Chris Church <cchurch@ansible.com> # Updated by Michael Crilly <mike@autologic.cm> # Updated by Anton Ouzounov <Anton.Ouzounov@careerbuilder.com> # Updated by Nicolas Simond <contact@nicolas-simond.com> # Updated by Dag Wieërs <dag@wieers.com> # Updated by Jordan Borean <jborean93@gmail.com> # Updated by Erwan Quélin <erwan.quelin@gmail.com> # Updated by David Norman <david@dkn.email> # # Version 1.0 - 2014-07-06 # Version 1.1 - 2014-11-11 # Version 1.2 - 2015-05-15 # Version 1.3 - 2016-04-04 # Version 1.4 - 2017-01-05 # Version 1.5 - 2017-02-09 # Version 1.6 - 2017-04-18 # Version 1.7 - 2017-11-23 # Version 1.8 - 2018-02-23 # Version 1.9 - 2018-09-21 # Support -Verbose option [CmdletBinding()] Param ( [string]$SubjectName = $env:COMPUTERNAME, [int]$CertValidityDays = 1095, [switch]$SkipNetworkProfileCheck, $CreateSelfSignedCert = $true, [switch]$ForceNewSSLCert, [switch]$GlobalHttpFirewallAccess, [switch]$DisableBasicAuth = $false, [switch]$EnableCredSSP ) Function Write-Log { $Message = $args[0] Write-EventLog -LogName Application -Source $EventSource -EntryType Information -EventId 1 -Message $Message } Function Write-VerboseLog { $Message = $args[0] Write-Verbose $Message Write-Log $Message } Function Write-HostLog { $Message = $args[0] Write-Output $Message Write-Log $Message } Function New-LegacySelfSignedCert { Param ( [string]$SubjectName, [int]$ValidDays = 1095 ) $hostnonFQDN = $env:computerName $hostFQDN = [System.Net.Dns]::GetHostByName(($env:computerName)).Hostname $SignatureAlgorithm = "SHA256" $name = New-Object -COM "X509Enrollment.CX500DistinguishedName.1" $name.Encode("CN=$SubjectName", 0) $key = New-Object -COM "X509Enrollment.CX509PrivateKey.1" $key.ProviderName = "Microsoft Enhanced RSA and AES Cryptographic Provider" $key.KeySpec = 1 $key.Length = 4096 $key.SecurityDescriptor = "D:PAI(A;;0xd01f01ff;;;SY)(A;;0xd01f01ff;;;BA)(A;;0x80120089;;;NS)" $key.MachineContext = 1 $key.Create() $serverauthoid = New-Object -COM "X509Enrollment.CObjectId.1" $serverauthoid.InitializeFromValue("1.3.6.1.5.5.7.3.1") $ekuoids = New-Object -COM "X509Enrollment.CObjectIds.1" $ekuoids.Add($serverauthoid) $ekuext = New-Object -COM "X509Enrollment.CX509ExtensionEnhancedKeyUsage.1" $ekuext.InitializeEncode($ekuoids) $cert = New-Object -COM "X509Enrollment.CX509CertificateRequestCertificate.1" $cert.InitializeFromPrivateKey(2, $key, "") $cert.Subject = $name $cert.Issuer = $cert.Subject $cert.NotBefore = (Get-Date).AddDays(-1) $cert.NotAfter = $cert.NotBefore.AddDays($ValidDays) $SigOID = New-Object -ComObject X509Enrollment.CObjectId $SigOID.InitializeFromValue(([Security.Cryptography.Oid]$SignatureAlgorithm).Value) [string[]] $AlternativeName += $hostnonFQDN $AlternativeName += $hostFQDN $IAlternativeNames = New-Object -ComObject X509Enrollment.CAlternativeNames foreach ($AN in $AlternativeName) { $AltName = New-Object -ComObject X509Enrollment.CAlternativeName $AltName.InitializeFromString(0x3,$AN) $IAlternativeNames.Add($AltName) } $SubjectAlternativeName = New-Object -ComObject X509Enrollment.CX509ExtensionAlternativeNames $SubjectAlternativeName.InitializeEncode($IAlternativeNames) [String[]]$KeyUsage = ("DigitalSignature", "KeyEncipherment") $KeyUsageObj = New-Object -ComObject X509Enrollment.CX509ExtensionKeyUsage $KeyUsageObj.InitializeEncode([int][Security.Cryptography.X509Certificates.X509KeyUsageFlags]($KeyUsage)) $KeyUsageObj.Critical = $true $cert.X509Extensions.Add($KeyUsageObj) $cert.X509Extensions.Add($ekuext) $cert.SignatureInformation.HashAlgorithm = $SigOID $CERT.X509Extensions.Add($SubjectAlternativeName) $cert.Encode() $enrollment = New-Object -COM "X509Enrollment.CX509Enrollment.1" $enrollment.InitializeFromRequest($cert) $certdata = $enrollment.CreateRequest(0) $enrollment.InstallResponse(2, $certdata, 0, "") # extract/return the thumbprint from the generated cert $parsed_cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2 $parsed_cert.Import([System.Text.Encoding]::UTF8.GetBytes($certdata)) return $parsed_cert.Thumbprint } Function Enable-GlobalHttpFirewallAccess { Write-Verbose "Forcing global HTTP firewall access" # this is a fairly naive implementation; could be more sophisticated about rule matching/collapsing $fw = New-Object -ComObject HNetCfg.FWPolicy2 # try to find/enable the default rule first $add_rule = $false $matching_rules = $fw.Rules | ?
