Hey all need some help.

[Final]

Whats up i just started working on a bot need some help with 0x50 packet i Send it out But i dont recieve anything back.

Heres my Setup

Code Select Expand


InsertDWORD(0);
     InsertNonNTString("68XIRATS");
     InsertDWORD(0xCF);
     InsertDWORD(0);
     InsertDWORD(0);
     InsertDWORD(0);
     InsertDWORD(0);
     InsertNTString("USA");
     InsertNTString("United States");
     SendPacket(0x50);

This is in C++ Dev-C++Compiler

Are you calling recv() ?

[Final]

shit wow that was fast lol
Ok i figured out what i did wrong I didnt setup socket well but now that i send it
it disconnects me .
Do i have to send something before 0x50 by any chance

[l2k-Shadow]

you're missing a DWORD

[Hero]

Before sending 0x50, send Chr(1).

Yeah, you need to send a protocol byte 0x01 for game, 0x02 for FTP file transfer.
If there is still a problem, and your socket is set up right, you will need to post a packet capture of your program, so we can pick through it
Checking a packet capture from your program Vs a packet capture from the client your trying to emulate, should help you alot with issues like this one

Like this?

     SendPacket(0x01);
     InsertDWORD(0);
     InsertNonNTString("68XIRATS");
     InsertDWORD(0xCF);
     InsertDWORD(0);
     InsertDWORD(0);
     InsertDWORD(0);
     InsertDWORD(0);
     InsertDWORD(0);
     InsertNTString("USA");
     InsertNTString("United States");
     SendPacket(0x50);

I still getting disconnected i dont understand wy

[Hdx]

chr(0x01) not packet 0x01
1 single byte, w/o anything else.

not packet 0x01, BYTE 0x01

im sorry but whats CHR()? im using c++ and how would i do a byte just add another DWORD? or WORD?

Well considering a Word is 2 bytes
And a DWord is 2 words
That would make a DWord 4 bytes....
just use send(0x01) or w/e the function to send data through your socket is in Cpp

send('\1');

Ok I have to this point

Code Select Expand


DWORD logontype=*(unsigned long *)(buffer+4);
           servertoken=*(unsigned long *)(buffer+sizeof(logontype));
           DWORD UPDValue=*(unsigned long *)(buffer+sizeof(servertoken));
           int time=(int)(buffer+sizeof(UPDValue));
           char* verfile=buffer+sizeof(time);
           char* valuestring=buffer+sizeof(verfile);
           int checkrev;
           checkrev=checkRevisionFlat(valuestring,"STAR/Starcraft.exe","STAR/storm.dll","STAR/battle.snp",time,??);

but what goes in the last arguement were it says ??..?

No, use a packet reader! .

Yeah I second that that will make your code... much cleaner and better.

now that we're past that part, you are reading the packet wrong.
logontype - fine
servertoken - fine
UPDValue (fyi it's UDP) - fine
time - that value is a FILETIME so it is 8 bytes long. definitely not an int.
verfile - that's fine just remember that BNCSUtil's CheckRevision() wants the mpq number, not the whole file, use extractMPQNumber() function
valuestring - fine

in last field goes your checksum variable, which is the whole point of doing CheckRevision(), the return value simply tells you if the function succeeded or not.
