How to check for port response

[Guest]

I understand how easy it is to use the my.computer.network.ping command, but
is it as easy to check for a response on a given port?

How can I check for a response for port x at 123.456.789?

for response ?




if you mean to check if a port is open or not


Imports System.Net.Sockets

Private Function TCP_Port_Open(ByVal ip As String, ByVal port As Integer) As
Boolean

Dim TcpPortscan As New TcpClient

Try

'Try to connect

TcpPortscan.Connect(ip, port)

' we are still here so this port is asumed open

Return True

Finally

TcpPortscan.Close()

End Try

End Function
