Smart-DoS Tracing the route and getting ping responses

RA1N · 01-20-2013, 07:04 AM

Using this you should easily be able to implement it into your program. This can also be used to test ping speeds and look at the amount of stress on all of the routing your server is taking.

So basically there is no built in method for Tracert in VB.Net sooo I did it the "cheap" way with finding an online one and using a HTTPWebRequest and splitting the source code if had as a result for the host.

Components:
1 Multilined Textbox : SourceBox (used to easily transfer to the listbox)
1 Normal Textbox : IP_Input
3 listboxes : TracertIPLstBox, PingTimeLstBox, TracertLstBox

Code:
Imports System.Net
Imports System.IO
Public Class Form1
    Dim s As String
    Dim h As String
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            If IP_Input.Text = Nothing Then
                MsgBox("Please inset the Host IP or URL in the textbox.")
                Return
            End If
            If IP_Input.Text.Contains("www") Or IP_Input.Text.Contains("net") Or IP_Input.Text.Contains("org") Or IP_Input.Text.Contains("gov") Then
                Dim Hostname = Dns.GetHostEntry(IP_Input.Text)
                Dim ip As IPAddress() = Hostname.AddressList
                If ip(0).ToString.Contains(":") Then
                    MsgBox("Invalid URL!")
                    Return
                Else
                    h = ip(0).ToString
                End If
            Else
                h = IP_Input.Text
            End If
            MsgBox("Getting Route for: " & h)
            MsgBox("This may take a bit based on your internet speed!, This is due to the HTTPWebRequest Used for routing!")
            TracertIPLstBox.Items.Clear()
            TracertLstBox.Items.Clear()
            PingTimeLstBox.Items.Clear()
            s = getSource("http://www.tracert.org/cgi-bin/traceroute/tracert.pl?t=" & h)
            Dim ss() = Split(s, "<PRE>")
            Dim sss() = Split(ss(1), "</PRE>")
            SourceBox.Text = sss(0)
            TracertLstBox.DataSource = SourceBox.Lines
            For i = 0 To TracertLstBox.Items.Count - 2
                Dim a() = Split(TracertLstBox.Items.Item(i), "  ")
                Dim aa() = Split(a(1), " (")
                Dim aaa() = Split(aa(1), ")")
                TracertIPLstBox.Items.Add(aaa(0))
                Dim b() = Split(a(2), " ")
                PingTimeLstBox.Items.Add(b(0))
            Next
        Catch ex As Exception
            MsgBox("Error: " & ex.Message)
            MsgBox("If you get an error it may have no connected to the website for routing")
        End Try
    End Sub

    Public Function getSource(ByVal url As String) As String
        Dim HTMLSource As String = ""
        Dim Request As HttpWebRequest = WebRequest.Create(url)
        Dim Response As HttpWebResponse = Request.GetResponse
        Dim SR As StreamReader
        SR = New StreamReader(Response.GetResponseStream)
        HTMLSource = SR.ReadToEnd
        SR.Close()
        Return HTMLSource
    End Function
End Class

I hope this helps someone. Probably the easiest way to do this but I just made it for an example of what you are essentially going for.

I think you deserve a lot more than what you have cause this method(not the code) was invented by you.
Thanks for sharing.

RA1N · 01-20-2013, 07:34 AM

Thank you the results I have gotten are in theory up to 100x more efficient by targeting the slowest server. I tested it on Google and its main server had a respond time of .6 ms and its slowest one was around 60 ms at the time so that literally 100x slower than the main one. Of course if you tried this on Google it would just create a new route due to an advanced ISP Networking plan, but on any small site this would be avoided, and cause a lot more damage than the average DoS.

ArkPhaze · 01-23-2013, 02:42 AM

The idea itself would work, but the code needs lots of cleaning up.

I don't see a need for these to be global:

Code:
Dim s As String
Dim h As String

Code:
If IP_Input.Text.Contains("www") Or IP_Input.Text.Contains("net") Or IP_Input.Text.Contains("org") Or IP_Input.Text.Contains("gov") Then

Should be using OrElse, although this kind of validation is a bit flawed too. Among a few other things, but you should probably be using MessageBox.Show() instead of the old MsgBox() as well.

There would be other ways to do this too...

just made this real quick as an example so people could use this to improve their projects.
