(“An existing connection was forcibly closed by the https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx remote host.”) up vote 2 down vote favorite 1 To summarize my situation, I am writing a server program that opens a UDP socket with which any number of clients can communicate. I receive UDP packets using code similar to the following: EndPoint sender = new IPEndPoint(IPAddress.Any, 0); try { count = socket.ReceiveFrom(buf, ref sender); // 'count' and 'buf' are defined elsewhere // If an exception isn't thrown, 'sender' will now contain the EndPoint http://stackoverflow.com/questions/13640546/how-do-i-determine-which-endpoint-caused-a-socketexception-with-error-code-10054 of the client that sent the packet. } catch(SocketException e) { if(e.ErrorCode == 10054) { // How do I get the EndPoint that caused the error? // The 'sender' variable above does not contain the EndPoint. } } I receive error code 10054 ("An existing connection was forcibly closed by the remote host") when my server sends a packet to a client that has closed its own socket. I would like to stop sending packets to that client so that SocketExceptions stop getting thrown, which severely hurts my server's performance. But my problem is that I don't know how to get the EndPoint of the particular client that was forcibly closed. (The 'sender' variable above isn't set to anything useful before the exception is thrown.) How can I find that EndPoint? A less-ideal but still workable solution would be to simply disable the SocketException from being thrown. Any ideas?

Google tells me this: Socket error 10054 may be the result of the remote server or some other piece of network equipment forcibly closing or resetting the connection But this is UDP. There is no connection. What exactly is causing this, and how socket error 10054 exactly can i avoid it? My temporary fix is to dispose the existing udpclient and instantiate another one, but that seems a bit stupid. The offending code is here: Code: private void EndReceive(IAsyncResult result) { try { IPEndPoint e = new IPEndPoint(IPAddress.Any, endpoint.Port); byte[] buffer = client.EndReceive(result, ref e); // Fire the event to indicate i've received a message if (MessageReceived != null) MessageReceived(buffer, e); } catch { // ignore } // This is the part which throws an exception randomly client.BeginReceive(EndReceive, null); } www.monotorrent.com For all your .NET bittorrent needs NOTE: My code snippets are just snippets.

Have you gotten similar errors with TCP?

I am working on a project for like 1 year now. Most of it works well. But somehow my socketenvironment craps out sometimes... For a totally unknown reason a socket crashes with 10054, connection refused. That socket usually processes easy packets with size being under 50, its a characterserver -> loginserver connection. Well, I found out it crashes after some time when the send() command got used. Before the "crashing" send() the app executed many other send()s, which are even the same functionspot, passing successfully. The odd thing is that only the server socket crashes, the socket at the client stays alive, which of course is being checked frame-by-frame by recv(). Sadly, this "poison" goes over to another socket of the same DLL and makes it "crash", too, the client->characterserver connection. Now I tell you about my "socketsystem". The core application has a simple loop which looks like that: Expand|Select|Wrap|Line Numbers while(IsActive()) { FOR_EACH_SERVER { ServerDLLFrame(); CheckNewConnections(); HandleAllClients(); } Sleep(1); } And this is the singlethreaded build option. Multithreaded looks similiar. CheckNewConnections() is a "accept" for my unencrypted and encrypted sockets. If accept() returns number above 0 I add this number as a socket to my list. HandleAllClients() is a read-and-execute function. It checks all clients in a loop if they have anything to send to me or just disconnected, without a Sleep() seperating recv() calls. If recv() returns 0, client disconnected. If recv() returns -1, error occurred or no data in buffer (WSAEWOULDBLOCK ?). And if recv() got some number above 0 it has put something into buffer and I process this. Yea. All sockets are non-block. And the last thing, which I think surely wont matter: All servers are being run on the same application, 3 in total. But what now? I really dont know how to fix this "little" bug :/ Do I need to let the app sleep 1msec after every recv() if I need to call a recv() afterwards? Is it needed to sleep 1msec before using send() after recv()? Is it okay to send 24kb data in one packet? Thanks for any help incoming :) TheGTA Jan 22 '09 #1 Post Reply
