This replaces the Get-NetAdapter call in previous versions, for all intents and purposes this is a decent subsititue. The reason why we want to perform this replacement is so that we don't have the dependency on the Get-NetAdapter and NetTCPIP module, as they are not available to PowerShell 6 Core. .OUTPUTS System.Net.NetworkInformation.SystemUnicastIPAddressInformation that has informaiton on the network card (actually the address assignment). #> [CmdletBinding()] [OutputType([System.Net.NetworkInformation.IPAddressInformation])] Param ( # Socket of the Client [Parameter(Mandatory = $true, HelpMessage = 'Add help message for user')] [ValidateNotNullOrEmpty()] [ValidatePattern('^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$')] [String] $IPAddress ) # Get a list of network adapters on the system $LocalAdapters = [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces() Write-Debug -Message ('Found {0} network interfaces' -f ($LocalAdapters.Count)) # Get the adapter that the endpoint is assigned to $NetworkAdapter = $LocalAdapters.ForEach({$_.GetIPProperties().UnicastAddresses}).where({$_.address -eq $IPAddress}) if ($NetworkAdapter.Count -ne 1) { Throw 'Unable to find correct network adapter' } $NetworkAdapter } |
