SEQUENCE_LOG how to fix on source

[avertuss 48]

Hi, I'm testing my server and syserr appeared in a sequence log:

SYSERR: Feb  7 10:23:40 :: Process: SEQUENCE 30bd5800 mismatch 0xaf != 0x64 header 254
SYSERR: Feb  7 10:23:40 :: Process: SEQUENCE_LOG [UNKNOWN]-------------
    [254 : 0xaf]

 

How i can fix it? In packet.h there is no such 254 header. Thanks for help.

Somebody know ?

Server:

In game/packet_info.cpp find this "Set(HEADER_CG_PONG, sizeof(BYTE), "Pong", true);"

replace with

"Set(HEADER_CG_PONG, sizeof(BYTE), "Pong", false);"

Client:

In PythonNetworkStream.cpp find function "bool CPythonNetworkStream::RecvPingPacket()" and change to:

Spoiler

bool CPythonNetworkStream::RecvPingPacket()
{
	Tracef("recv ping packet. (securitymode %u)\n", IsSecurityMode());

	TPacketGCPing kPacketPing;

	if (!Recv(sizeof(TPacketGCPing), &kPacketPing))
		return false;

	m_dwLastGamePingTime = ELTimer_GetMSec();

	TPacketCGPong kPacketPong;
	kPacketPong.bHeader = HEADER_CG_PONG;

	if (!Send(sizeof(TPacketCGPong), &kPacketPong))
		return false;

	//if (IsSecurityMode())
	//	return SendSequence();
	//else
	return true;
}

In AccountConnector.cpp find "bool CAccountConnector::__AuthState_SendPong()" and change to:

Spoiler

bool CAccountConnector::__AuthState_SendPong()
{
	TPacketCGPong kPacketPong;
	kPacketPong.bHeader = HEADER_CG_PONG;

Hello,

I've seen a lot of questions about header 254 error in server logs, and all what I've found were diffs for binaries. Below you will find a way how to fix it in source.

Let's start:

SERVER:

In game/packet_info.cpp find this "Set(HEADER_CG_PONG, sizeof(BYTE), "Pong", true);" replace with "Set(HEADER_CG_PONG, sizeof(BYTE), "Pong", false);"

CLIENT:

All changes will be in UserInterface folder:

In PythonNetworkStream.cpp find function "bool CPythonNetworkStream::RecvPingPacket()" and change to:

bool CPythonNetworkStream::RecvPingPacket()
{
	Tracef("recv ping packet. (securitymode %u)\n", IsSecurityMode());

	TPacketGCPing kPacketPing;

	if (!Recv(sizeof(TPacketGCPing), &kPacketPing))
		return false;

	m_dwLastGamePingTime = ELTimer_GetMSec();

	TPacketCGPong kPacketPong;
	kPacketPong.bHeader = HEADER_CG_PONG;

	if (!Send(sizeof(TPacketCGPong), &kPacketPong))
		return false;

	//if (IsSecurityMode())
	//	return SendSequence();
	//else
	return true;
}

 

In AccountConnector.cpp find

"bool CAccountConnector::__AuthState_SendPong()"

and change to:

bool CAccountConnector::__AuthState_SendPong()
{
	TPacketCGPong kPacketPong;
	kPacketPong.bHeader = HEADER_CG_PONG;
	if (!Send(sizeof(kPacketPong), &kPacketPong))
		return false;

	//if (IsSecurityMode())
	//return SendSequence();

	return true;
}

 

In GuildMarkDownloader.cpp find

"bool CGuildMarkDownloader::__LoginState_RecvPing()"

and change to:

Spoiler

bool CGuildMarkDownloader::__LoginState_RecvPing()
{
	TPacketGCPing kPacketPing;

	if (!Recv(sizeof(kPacketPing), &kPacketPing))
		return false;

	TPacketCGPong kPacketPong;
	kPacketPong.bHeader = HEADER_CG_PONG;

	if (!Send(sizeof(TPacketCGPong), &kPacketPong))
		return false;

	//if (IsSecurityMode())
	//return SendSequence();
	//else
	return true;
}

In GuildMarkUploader.cpp find

"bool CGuildMarkUploader::__LoginState_RecvPing()"

and change to:

Spoiler

bool CGuildMarkUploader::__LoginState_RecvPing()
{
	TPacketGCPing kPacketPing;
	if (!Recv(sizeof(kPacketPing), &kPacketPing))
		return false;

	TPacketCGPong kPacketPong;
	kPacketPong.bHeader = HEADER_CG_PONG;

	if (!Send(sizeof(TPacketCGPong), &kPacketPong))
		return false;

	//if (IsSecurityMode())
	//return SendSequence();
	//else
	return true;
}

I think this just disables it so it not showed in syserr, but the error is still going on the server background.

[Haruka 15]

Not. With my help you can solve the problem

[wezt 95]

@Haruka you could just send a link to https://metin2dev.org/board/index.php?/topic/10834-fix-sequence-mismatch-header-254-c/ or at least didn't tell that it's your solution

[Haruka 15]

I said: 'with my help' and not 'it's my solution'

 

[БlyatMAN 13]

this is just a bypass not solving the problem
