IP connection limit

[Haarhus]

Hey guys is there a way to limit the connection from the same ip to 2 connections ? to avoid perhaps multiboxing e.t.c ? Couldnt really find anything about that in the forum nor in the google , if there is something i probably missed it .

maybe @Mecanik can answer u that

[Mecanik]

Yes there is, depends on your server, are you using webzen IOCP ?

[Haarhus]

Zteam s8 files , they have glitch with the data server bugging when there are more than ~90 people online and i want to make a temporal limit so everybody can join not just 5 people with 50 accs until it get fixed

[Mecanik]

Well limiting people from entering the game is not a solution lol...
Debug the dataserver to see what`s causing the problem.

We solved part of the problem , it still happens but we needed a temporal solution so it doesnt bug while we try to fix it.

Well then you could just search through your object list, and if the ip is there allready, refuse it ( return -1 )
If you don`t know how to do that, create a function/class like this:

bool CheckIpAddress(char* IpAddress)
{
	std::map<std::string,IP_ADDRESS_INFO>::iterator it = this->m_IpAddressInfo.find(std::string(IpAddress));

	if(it == this->m_IpAddressInfo.end())
	{
		return ((MaxIpConnection==0)?0:1);
	}
	else
	{
		return ((it->second.IpAddressCount>=MaxIpConnection)?0:1);
	}
}

void InsertIpAddress(char* IpAddress)
{
	IP_ADDRESS_INFO info;

	strcpy_s(info.IpAddress,IpAddress);

	info.IpAddressCount = 1;

	std::map<std::string,IP_ADDRESS_INFO>::iterator it = this->m_IpAddressInfo.find(std::string(IpAddress));

	if(it == this->m_IpAddressInfo.end())
	{
		this->m_IpAddressInfo.insert(std::pair<std::string,IP_ADDRESS_INFO>(std::string(IpAddress),info));
	}
	else
	{
		it->second.IpAddressCount++;
	}
}

void RemoveIpAddress(char* IpAddress)
{
	std::map<std::string,IP_ADDRESS_INFO>::iterator it = this->m_IpAddressInfo.find(std::string(IpAddress));

	if(it != this->m_IpAddressInfo.end())
	{
		if((--it->second.IpAddressCount) == 0)
		{
			this->m_IpAddressInfo.erase(it);
		}
	}
}

And use it in your server manager on new connection / add object:

InsertIpAddress(IPADDRESS);

Sorry I`m at work, and this code is just taken from another source, hope you understand.
