versioncheckex2 issue.

[fuzan]

Hey,


I've been continuing my bot project a little more, and after a lot of refactoring I've made it to implementing the login sequence. Sadly, S0x1A (broodwars) always fails. I've spent an hour trying to figure out what's the issue and now I'm sleepy. Hopefully one of you with sharp eyes may spot my fault.

It would probably help to not send defunct packets.

[brew]

How the hell is 0x1A defunct... It's currently the most advanced BNLS checksum packet made, and just about everybody on these forums use it.

What I use:

Code Select Expand


Public Sub BNLSSend0x1A()
    With pbuffer
        .InsertDWORD GetClient(Bot.Client) 'The client code for BNLS
        .InsertDWORD 0 'Flags, must be set to 0 for now.
        .InsertDWORD &H3713 'cookie :D
        .InsertNonNTString Bot.mpqFileTime †
        .InsertNTString Bot.mpqName ††
        .InsertNTString Bot.ChecksumFormula 'Checksum formula.
        .SendBNLSPacket &H1A
    End With
End Sub

Public Function GetClient(Client As String) As Long
    On Error GoTo Err
    Select Case Client
        Case "STAR": GetClient = 1
        Case "SEXP": GetClient = 2
        Case "W2BN": GetClient = 3
        Case "D2DV": GetClient = 4
        Case "D2XP": GetClient = 5
        Case "JSTR": GetClient = 6
        Case "WAR3": GetClient = 7
        Case "W3XP": GetClient = 8
        Case Else: GetClient = 0
    End Select
    Exit Function
Err:
    GetClient = 1
End Function


†'What I just did for this was.... (in the S > C 0x50) Bot.mpqFileTime = Mid(Data, 17, Works great, and it's easier to do it this way because VB6 can't handle unsigned 64 bit data types.

††'The file name of the mpq-- BNLS can extract the mpq number itself, taking some load off your bot

Anotherwords, I think you're sending what is supposed to be the cookie and flags in the reverse order. Like I said-- The flags MUST be set to 0, and the cookie value can be anything. I hope this helps
edit** haha, i brainfartted too. You're sending them in the correct order, your packetlog breaks it up in groups of 64 bits that kinda confuzzled me for a second

[Hdx]

he's sending this to BNLS, but what server?
His packet looks right.
~Hdx
[edit]
Brew, I fucking hate you, CHECK YOUR CODE BEFORE YOU POST. Don't break the god dammen tables.
Good you fixed it
~Hdx

[rabbit]

Wow.  Brainfart.  I thought he was talking about BNCS 0x1a, which is defunct, not BNLS 0x1a :X

[fuzan]

Still, no luck.

Are we not supposed to be using "bnls.valhallalegends.com" ?

[Mystical]

You can! but also you can check here for other servers including BNLS & JBLS and to see which ones are running compliments of HDX =)

http://jbls.org/?p=Servers

Note:

Starcraft, Starcraft Broodwar, Warcraft II only work on the BNLS server and IP listed BNLS servers.
Warcraft III only works on JBLS servers.
Diablo II is lame and works on both =)

[Hdx]

JBLS dosent support lockdown yet, so thats why I asked.
Post a full log, including ips.
Everything looks right. so...
~Hdx

[fuzan]

Still, same issue.
Here are some example representations of the data I'm receiving/sending.

Code Select Expand


S0x50 {
  s50_logonType = 0, 
  s50_serverToken = 2111859351,
  s50_udpValue = 2102977,
  s50_mpqFiletime = 128067209560000000,
  s50_IX86ver = LPS ["lockdown-IX86-11.mpq\NUL"],
  s50_valueString = LPS ["|RP\239\179\f\221\180\v\202\155\223A\135b\180\NUL"]
}


From this, I construct:

Code Select Expand


BNLS_C0x1A {
  lc1A_productID = 2,
  lc1A_flags = 0,
  lc1A_cookie = 0,
  lc1A_mpqFiletime = 128067209560000000,
  lc1A_IX86ver = LPS ["lockdown-IX86-11.mpq\NUL"],
  lc1A_valueString = LPS ["|RP\239\179\f\221\180\v\202\155\223A\135b\180\NUL"]
}


[Mystical]

I feel like a dumbass, but im not quite sure exactly what language that is?

[brew]

Hrm... possibly java.

[fuzan]

Those aren't my datastructures. They're members of Haskell's "Show" Typeclass, I just printed them out.

Here's my function that constructs and sends the versioncheck packet.
As you can see, it takes a handle (bnls), and three parameters (a,b,c).

Code Select Expand


bnls_version_check bnls a b c = do
  putStrLn "bnls_version_check"
  let packet = BNLS_C0x1A { lc1A_productID   = 0x02
                          , lc1A_flags       = 0
                          , lc1A_cookie      = 0
                          , lc1A_mpqFiletime = a
                          , lc1A_IX86ver     = b
                          , lc1A_valueString = c }
  print packet
  sendPacket bnls packet
  bnls2Type bnls :: IO BNLS_S0x1A



Here I instantiate the values a,b,c that are passed to the function that sends the packet:

Code Select Expand


  let a = s50_mpqFiletime rauth :: Word64
  let b = s50_IX86ver rauth     :: B.ByteString
  let c = s50_valueString rauth :: B.ByteString
 
  rcheck <- bnls_version_check bnls a b c


[fuzan]

I think what I should ask is:
Are the values I'm using for making the 0x1A correct? Are the last three fields supposed to come from the s0x50 as I'm currently doing?

[Hdx]

Ya its fine but...

Post a full log, including ips.

My BNLS connection is the standard valhalla something or another one: 63.161.183.205

As you can see, it works perfectly with versionbyte. It also works perfectly with ckdey, however, I've omitted its call.
