- # Test-Port.ps1
- # Does a TCP connection on specified port (135 by default)
- $ErrorActionPreference = "SilentlyContinue"
- # Create TCP Client
- $tcpclient = new-Object system.Net.Sockets.TcpClient
- # Tell TCP Client to connect to machine on Port
- $iar = $tcpclient.BeginConnect($srv,$port,$null,$null)
- # Set the wait time
- $wait = $iar.AsyncWaitHandle.WaitOne($timeout,$false)
- # Check to see if the connection is done
- if(!$wait)
- {
- # Close the connection and report timeout
- $tcpclient.Close()
- if($verbose){Write-Host "Connection Timeout"}
- Return $false
- }
- else
- {
- # Close the connection and report the error if there is one
- $error.Clear()
- $tcpclient.EndConnect($iar) | out-Null
