    small but effective tool(if u know the rite way to use it..u might do wonders..)

    --------------------
    you need:

    2 textboxes
    1 listbox
    3 commandbuttons
    1 timer
    1 winsock control
    --------------------
    Code:
    Private Sub Command1_Click()
      Timer1.Enabled = True
    End Sub
    
    Private Sub Command2_Click()
      Timer1.Enabled = False
      Text2.Text = "0"
    End Sub
    
    Private Sub Command3_Click()
      List1.Clear
    End Sub
    
    Private Sub Timer1_Timer()
      On Error Resume Next
      Winsock1.Close
      Text2.Text = Int(Text2.Text) + 1
      Winsock1.RemoteHost = Text1.Text
      Winsock1.RemotePort = Text2.Text
      Winsock1.Connect
    End Sub
    
    Private Sub Winsock1_Connect()
     List1.AddItem Winsock1.RemotePort & " is open!"
    End Sub
    
    --------------------
    explanation:

    text1 = IP to scan
    text2 = starting port
    list1 = list where all open ports are shown
    command1 = start
    command2 = stop and reset
    command3 = clear port list
    timer1 = will make the winsock control to try ports

    Tis hokay.This has inspired me to create a port scanner in PHP, of which, every time you scan you will have a proxy for yourself, namely, my site.I still like this one, though.I think Ill use Perl to develop most of my tools from here on in. And, if I get good enough, start porting them to C.
