Supported parameters to pass in for cmdlet: - idrac_ip: Pass in iDRAC IP - idrac_username: Pass in iDRAC username - idrac_password: Pass in iDRAC password - x_auth_token: Pass in iDRAC X-Auth token session to execute cmdlet instead of username / password (recommended) - get_certs: Pass in "y" to get current iDRAC certs - replace_cert_id: Replace cert, pass in the cert id. - replace_cert_filename: Replace cert, pass in the signed cert filename - reset_idrac: Reset iDRAC, pass in "y". After you replace cert, reset iDRAC is needed for the changes to take affect. .EXAMPLE Invoke-ReplaceCertificateREDFISH -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -get_certs y # This example will get current iDRAC certs. .EXAMPLE Invoke-ReplaceCertifiateREDFISH -idrac_ip 192.168.0.120 -get_certs y # This example will first prompt for iDRAC username/password using Get-Credential, then get current iDRAC certs. .EXAMPLE Invoke-ReplaceCertificateREDFISH -idrac_ip 192.168.0.120 -get_certs y -x_auth_token 7bd9bb9a8727ec366a9cef5bc83b2708 # This example using iDRAC X-auth token session will get current iDRAC certs. .EXAMPLE Invoke-ReplaceCertifiateREDFISH -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -replace_cert_id "SecurityCertificate.1" -replace_cert_filename signed.cer # This example will replace certificate 'SecurityCertificate.1' .EXAMPLE Invoke-ReplaceCertifiateREDFISH -idrac_ip 192.168.0.120 -reset_idrac y # This example will first prompt for iDRAC username/password using Get-Credential, then reset iDRAC. #> function Invoke-ReplaceCertificateREDFISH { # Required, optional parameters needed to be passed in when cmdlet is executed param( [Parameter(Mandatory=$True)] [string]$idrac_ip, [Parameter(Mandatory=$False)] [string]$idrac_username, [Parameter(Mandatory=$False)] [string]$idrac_password, [Parameter(Mandatory=$False)] [string]$x_auth_token, [Parameter(Mandatory=$False)] [string]$get_certs, [Parameter(Mandatory=$False)] [string]$replace_cert_id, [Parameter(Mandatory=$False)] [string]$replace_cert_filename, [Parameter(Mandatory=$False)] [string]$reset_idrac ) # Function to ignore SSL certs function Ignore-SSLCertificates { $Provider = New-Object Microsoft.CSharp.CSharpCodeProvider $Compiler = $Provider.CreateCompiler() $Params = New-Object System.CodeDom.Compiler.CompilerParameters $Params.GenerateExecutable = $false $Params.GenerateInMemory = $true $Params.IncludeDebugInformation = $false $Params.ReferencedAssemblies.Add("System.DLL") > $null $TASource=@' namespace Local.ToolkitExtensions.Net.CertificatePolicy { public class TrustAll : System.Net.ICertificatePolicy { public bool CheckValidationResult(System.Net.ServicePoint sp,System.Security.Cryptography.X509Certificates.X509Certificate cert, System.Net.WebRequest req, int problem) { return true;
