Someone is connecting on the game port instead of the login port.

Is there anyway to prevent this, because I'm pretty sure it crashed my server <_<

 

[SpiderOT]

i get this msg before autoBanishUnknownBytes ban someone if i am not wrong this happen when ppl bot in your server

 

[trou]

This is not crashing your server. I'm 99% sure.

This happens when somebody connects to server with proxy based bot (like BlackD, Elfbot).

It's not unsafe. You can ignore such messages.

Okay, thanks Kula_

 

[hans henrik]

also happens when idiots try to connect with telnet/wrong client version/their browser/ for example

[Failure - Protocol::XTEA_decrypt] Not valid unencrypted message size

i have the same error, and my laggs my server for few minutes.

 

[stian]

Just drop the connection without writing the message. Printing is a blocking call, so the thread can't do anything else while the message writes, witch means that it might lag for a few ms. As far as I remember this should trigger anything that could lag your server for several minutes.

So why does it freeze my server permanently ?

 

[Johanz]

freezes my server to :S

 

[emperia]

[Milice]

The XTEA is RSA, Wront RSA = XTEA error!

 

[nystrom]

[Failure - Protocol::XTEA_decrypt] Not valid unencrypted message size (IP: xx.xxx.xx.xxx)

i asked the person which bot he connected with and the answer was Ngbot.

Try replace function (ofc, not tested!)

void Protocol::onRecvMessage(NetworkMessage& msg)

void Protocol::onRecvMessage(NetworkMessage& msg)
{
	#ifdef __DEBUG_NET_DETAIL__
	std::cout << "Protocol::onRecvMessage" << std::endl;
	#endif
	if(m_encryptionEnabled)
	{
		#ifdef __DEBUG_NET_DETAIL__
		std::cout << "Protocol::onRecvMessage - decrypt" << std::endl;
		#endif
		if (!XTEA_decrypt(msg) && g_config.getBool(ConfigManager::BAN_UNKNOWN_BYTES))
		{
			int64_t banTime = -1;
			ViolationAction_t action = ACTION_BANISHMENT;
			Account tmp = IOLoginData::getInstance()->loadAccount(player->getAccount(), true);

			tmp.warnings++;
			if(tmp.warnings >= g_config.getNumber(ConfigManager::WARNINGS_TO_DELETION))
				action = ACTION_DELETION;
			else if(tmp.warnings >= g_config.getNumber(ConfigManager::WARNINGS_TO_FINALBAN))
			{
				banTime = time(NULL) + g_config.getNumber(ConfigManager::FINALBAN_LENGTH);
				action = ACTION_BANFINAL;
			}
			else
				banTime = time(NULL) + g_config.getNumber(ConfigManager::BAN_LENGTH);
				
			if(IOBan::getInstance()->addAccountBanishment(tmp.number, banTime, 13, action,
				"Sending not valid unencrypted message to the server.", 0, player->getGUID()))
			{
				IOLoginData::getInstance()->saveAccount(tmp);
				player->sendTextMessage(MSG_INFO_DESCR, "You have been banished.");
				
				g_game.addMagicEffect(player->getPosition(), MAGIC_EFFECT_WRAPS_GREEN);
				Scheduler::getInstance().addEvent(createSchedulerTask(1000, boost::bind(
					&Game::kickPlayer, &g_game, player->getID(), false)));
			}
		}
	}

	parsePacket(msg);
}

And change in config.lua

autoBanishUnknownBytes = true -- from false

Now, when somebody send to the server "not valid unencrypted message", he will be banned.
