AcceptAsync with multiples clients

Monkey Forums/Monkey Beginners/AcceptAsync with multiples clients

I am trying to make a server communicate with many clients.
I can start a server who is communicating with only one client.

But even if I create multitples sockets when I call from host the function nameofsocket[array].AcceptAsync(Self) only accepts the first client and ignores all the others clients.

What can I do?

You should implement ServerSocket type of sockets.

From M-X docs:

Class HttpServer Implements IOnAcceptComplete

	Method New( port:Int = 8090)
		_socket=New Socket( "server" )
		If Not _socket.Bind( "",port ) Error "Bind failed"
		_socket.AcceptAsync( Self )
	End
	
	Private
	
	Field _socket:Socket
	
	Method OnAcceptComplete:Void( socket:Socket,source:Socket )
		If Not socket Error "Accept error"
		Print "HttpServer: Accepted client connection"
		Local client:=New HttpServerClient( socket )
		'set accept waiting again
		_socket.AcceptAsync( Self )
	End

One connection client

Class HttpServerClient Implements IOnSendComplete,IOnReceiveComplete

	Method New( socket:Socket )
		_socket=socket
		_socket.ReceiveAsync _data,0,_data.Length,Self
	End
	
	Private
	
	Field _socket:Socket
	Field _data:=New DataBuffer( 2048 )
	
	Method OnReceiveComplete:Void( data:DataBuffer,offset:Int,count:Int,source:Socket )
		Print "HttpServer: Get data " + data.PeekString(0, count)
		If True 'Not count
			Print "HttpServer: Closing client connection"
			_socket.Close()
			Return
		Endif
		'_socket.SendAsync data,offset,count,Self
	End

	Method OnSendComplete:Void( data:DataBuffer,offset:Int,count:Int,source:Socket )
		'_socket.ReceiveAsync _data,0,_data.Length,Self
	End
	
	Method GetRequestHeader:Void()
	End Method
	
End Class 'HttpServerClient

But, anyway, M-X doesn't support multithread processing therefore while an one connection is processing all others are waiting when their On...events will be called.

I am using Tcp , i got from mark on bananas and from this topic : http://www.monkeycoder.co.nz/Community/posts.php?topic=7698
it's very similar from what you posted :).

btw, changing the ports works real nice! thanks!

But my objective is to have many connection , more than hundreds.

I could create in the server with AcceptAsync for hundreds of ports actives. And for the clients with ConnectAsync for those hundreds ports, and a FOR to try to connect to one port in the server, if doesn't , it could try another port.

but gerating one different port for each client could be bad, since it could be in conflict with other program who is using that port.

I was think something like, terraria, minecraft, tibia, who has just one port opened from the client.

One possible solution could be:
A host who opens many ports, the clients connects to those ports but the clients have the same number of port. Example:
Server port 90 responds the client 1 port 80
Server port 80 responds the client 2 port 80
Server port 70 responds the client 3 port 80
Server port 50 responds the client 4 port 80
Server port 40 responds the client 5 port 80
Server port 30 responds the client 6 port 80
Server port 20 responds the client 7 port 80
Server port 10 responds the client 8 port 80

but I don't know how to do that since ConnectAsync uses a host string to connect.

MS Windows allows connection to 1024-65534 ports. Don't worry about free ports. Use ServerSocket/Bind Connection for.

Usually udp is used for mega "connections" servers - it's fast and no port limitations.

thanks!! I will try to build something with udp!!! :)

What's wrong with using just one port for all connections from clients?

Xaron, I would like to do it. It would be real nice , but I am failing to do this in TCP.
For UDP I am trying. (just need some free time to try in UDP , my work don't let me) :)
