Too many connections.

Hello people. I'm trying to find a solution about the socket on Habboon emulator.
My problem is that I've a proxy and I must set up the conperip to 1000 because, if I set up it to 3 for example, I got the error "Too many connections [ip]". So: the connection arrives from proxy that is 1 ip for example x.x.x.x.
So, if one noob use a flooder to my proxy ip I've too many connections on my server from x.x.x.x.
Reading the code, I saw that:

Code:

---

try
                    {
                        Socket replyFromComputer = ((Socket)iAr.AsyncState).EndAccept(iAr);
                        replyFromComputer.NoDelay = disableNagleAlgorithm;

                        string Ip = replyFromComputer.RemoteEndPoint.ToString().Split(':')[0];

                        int ConnectionCount = getAmountOfConnectionFromIp(Ip);
                        if (ConnectionCount < maxIpConnectionCount)
                        {
                            _acceptedConnections++;
                            ConnectionInformation c = new ConnectionInformation(_acceptedConnections, replyFromComputer, this, parser.Clone() as IDataParser, Ip);
                            reportUserLogin(Ip);
                            c.connectionChanged += c_connectionChanged;

                            if (connectionEvent != null)
                                connectionEvent(c);
                        }
                        else
                        {
                            log.Info("Connection denied from [" + replyFromComputer.RemoteEndPoint.ToString().Split(':')[0] + "]. Too many connections (" + ConnectionCount + ").");
                        }
                    }
                    catch
                    {
                    }
                    finally
                    {
                        connectionListener.BeginAccept(newConnectionRequest, connectionListener);
                    }

And I want that the emu accepts the connection from the RealIP that connect to my proxy.
For example: I'm using Cloudflare, but to get the realIP of an user I'm using the var $_SERVER['HTTP_CF ecc]'.
So, do you have any idea?
Thank you.

I don't need that at all, I use cloudflare and it works great... Increase your limit if that's the issue.

I'm using cloudflare too.. The problem is that. If I increase the limit and I receive a DDoS on my proxy , on my emulator I've X connections. For example. I set up it a 10k conperip? If I receive a DDoS I will have 9k online or high random number. In counter of cms I'm using a count, but my problem is too that my CPU goes to an high usage.

Any other solution?

Having the same problem...

The solution would be, have 2 VPS servers, maybe a 1G to host your cms files, the other one a higher spec (depending on the size of your hotel) to host your database and emulator, no need for a proxy then if your VPS are ddos protected.

I am sure if you contact your provider they will be able to host both vps for you on the same node so you will have no lag issues between your cms and mysql connection.

Another solution is that insert your real ip in swf file, and in the connection.info.host your tcp proxy. It works fine for me..

You can do that, then when a user decides to use netstat or tcpview your ip address is open to anyone

Johno, is it common pratice for retros to use 2 vps?

Some hotels do, I know a few that we host (I cannot share links due to privacy) but they use 2 vps for hotels

I'm currently have this issue:

Code:

wtf?

Find solution.

However: reading stackoverflow I found this.

Code:

---

string header = Request.Headers["Via"] ?? Request.Headers["X-Forwarded-For"];
if (!string.IsNullOrEmpty(header))
{
    // probably the request was forwarded from a proxy server
    // but you cannot be 100% sure as HTTP request headers can be faked
}

Can it help us?
another method:

Code:

---

protected void GetUser_IP()
{
    string VisitorsIPAddr = string.Empty;
    if (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
    {
        VisitorsIPAddr = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
    }
    else if (HttpContext.Current.Request.UserHostAddress.Length != 0)
    {
        VisitorsIPAddr = HttpContext.Current.Request.UserHostAddress;
    }
    uip.Text = "Your IP is: " + VisitorsIPAddr;
}

"PROCEDURE cms_int.c does not exist"

You are missing that
