Function Receive-TCPMessage {
Param (
[Parameter(Mandatory=$true, Position=0)]
[ValidateNotNullOrEmpty()]
[int] $Port
)
Process {
Try {
# Set up endpoint and start listening
$endpoint = new-object System.Net.IPEndPoint([ipaddress]::any,$port)
$listener = new-object System.Net.Sockets.TcpListener $EndPoint
$listener.start()
# Wait for an incoming connection
$data = $listener.AcceptTcpClient()
# Stream setup
$stream = $data.GetStream()
$bytes = New-Object System.Byte[] 1024
# Read data from stream and write it to host
while (($i = $stream.Read($bytes,0,$bytes.Length)) -ne 0){
$EncodedText = New-Object System.Text.ASCIIEncoding
$data = $EncodedText.GetString($bytes,0, $i)
Write-Output $data
}
# Close TCP connection and stop listening
$stream.close()
$listener.stop()
}
Catch {
