[C++] "Family Friendly" version checker

[Guest Ezrekith]

Hi folks!

 

Basically you check the version from the client src and from the auth version file and if its not correct the client will give you a popup msg at the login phase like: "Your client is outdated as fun , please use the patcher program!"

Lets go:
 

Binary / packet.h

 

Search for:

typedef struct command_login3

Add this into the list:

DWORD	dwClientKey;

 

Binary / AccountConnector.cpp

Add #include "Locale_inc.h" into your includes

Search for:

m_strPassword = "";

You can see this little friend right there:

		for (DWORD i = 0; i < 4; ++i)
			LoginPacket.adwClientKey[i] = g_adwEncryptKey[i];

Replace with this:

		for (DWORD i = 0; i < 4; ++i)
			LoginPacket.adwClientKey[i] = g_adwEncryptKey[i];

		LoginPacket.dwClientKey = KLIENS_VERZIO_SZAMSOR;

 

Binary / Locale_inc.h

Add this:

#define KLIENS_VERZIO_SZAMSOR 3333

 

Server Source / game / packet.h

Search for:

typedef struct command_login3

Add this into the list:

DWORD	dwClientNumber;

 

Server Source / game / input_auth.cpp

 

Search for:

TPacketCGLogin3 * pinfo = (TPacketCGLogin3 *) c_pData;

Add above:

	DWORD dwClientNumber;
	str_to_number(dwClientNumber, g_stClientVersion.c_str());

Search for this:

	if (!g_bAuthServer)
	{
		sys_err ("CInputAuth class is not for game server. IP %s might be a hacker.", 
			inet_ntoa(d->GetAddr().sin_addr));
		d->DelayedDisconnect(5);
		return;
	}

Add under this:

	if (dwClientNumber != pinfo->dwClientNumber)
	{
		LoginFailure(d, "VERSION");
		return;
	}

 

Now go to your cd /usr/game/auth folder

-Create a file named VERSION

-Write 3333 into it

 

Client / root / intrologin.py

Search for this:

self.loginFailureMsgDict={

Add this into the list:

"VERSION"	: "Your client is outdated as fun ;) , please use the patcher program!",

 

Have fun with it!

 

EDIT:
 

If you don't have the client version check enabled:

Server Source / game / config.cpp

Search for this:

// END_OF_LOG_KEEP_DAYS_EXTEND

Add under this:

LoadClientVersion();
