HubBOT.NET Project

[djechelon]

Hello,
I am a PublicHubList owner. My list is based on other lists' data, and I noticed many hubowners are faking the usercount on the main Hublists like Dreamland.

I wrote a topic about "spidering" hubs. Now I have begun to code a VB.NET program that connects to hubs in PublicList, counts the users (and maybe the sharesize too) and leaves the hub.
I've managed to connect and retrieve hub name and description. Now I need to get user list.

The program logs into the hub with fake sharesize and tag correctly. But, when managing sockets, I need to get the HUGE stream of the userlist (I am testing it on a 1000 people hub), the socket stream is cut. Also, when placing all socket data into a logfile, there are many and many white spaces.

This is the code of my ReadSocket function

Code: Select all

    Private Function LeggiSocket(ByRef Hubsock As TcpClient) As String

        While Not Hubsock.GetStream.DataAvailable()
            Application.DoEvents()
        End While
        If Hubsock.GetStream.DataAvailable() Then
            Dim InBuffer(Hubsock.ReceiveBufferSize) As Byte
            Hubsock.GetStream().Read(InBuffer, 0, Hubsock.ReceiveBufferSize)
            Return System.Text.Encoding.Default.GetString(InBuffer).Trim()
        Else
            Return "No dati"
            Exit Function
        End If
    End Function

In this example, the socket is already open and the function simply returns a text string. I need the Byte variable to be automatically sized matching the socket stream's length.

Any help? How does DC++ (in C++ language of course) get the userlist via socket stream? I'm new to C++, but if anybody tell me the exact position of the code with some explanation I can simply port the code to my application.

Thank you for your help.

I think that might be your first problem.

Anyway, NmdcHub.cpp/h might be a good place to start looking.

By the way I have another problem.
When completing the Hub querying i use

Code: Select all

Hubsock.Close()

But i noticed that the BOT is still inside the hub. When I close the entire application the BOT disconnects from the hub.

Anyway about Nmdc.cpp, it's too difficult for me (I'm learning VB.net because it's easier to read and because Visual Studio automatically shows available Properties & Methods, and even warns you about many errors before compiling).
Anyway, from what I understood from that file, the data socket reading is left to the socket object itself. Any more ideas?

Any help? How does DC++ (in C++ language of course) get the userlist via socket stream?

DC++ may not get the user list at all - look at extensions.txt at the NoHello $Supports.

If you're doing something wrong protocol wise, use Ethereal. If you're doing something wrong code wise, I would look on VB.NET forums.

Chimera is a bot written in VB.NET (source released under GPL), that can login to a hub and has a working socket stream handler. Perhaps it can give you some help.

Note: the "spider" you describe already exists, and is used by just about every hublist out there.. it's usually called a "Pinger".
