     The solution is to change network_mode in config.toml configuration file of runner.

     [[runners]] name="myrunner" [[runners.docker]] network_mode="host"-

     You can delete this line(network_mode="host") and docker will use bridge mode by default.

   • Networking in Java, 'readLine()' on multiple lines of response in client

     Top Answer

     Answered Nov 19, 2016 · 0 votes

     Hm i got it to work with netcat, e.g.:

     nc -l -p 31337-

     After starting netcat you can type in some input which will be sent to the client after connecting.

     So with netcat it works. I would recommend to use variables just for one purpose.

     while(true){ /* Flushing buffer */ String SvMessage; while (!receiver.ready()){} //wait for buffer /* Printing the resulting response from the server */ while (receiver.ready()){ SvMessage = receiver.readLine(); System.out.println(SvMessage); } /* Get input message from the user */ String userMessage = "hello"; /* If the user inputs "exit", then the program terminates */ if (userMessage.equals("exit")) System.exit(1); /* If not exit, send the message to server */ sender.print(userMessage + "\r\n"); }

     I made some changes: 1.) changed while condition to br.ready() 2.) instead of PrintStream.println using PrintStream.print(message + "\r\n) 3.) not using a BufferedReader for userinput, just sending "commands" (or hello) 4.) added while (!receiver.ready()){} to wait for buffer to fill

     So the client will now always reply to the server with new commands (or "hello"). =)

     Hope this helps

     Check out gamekit. Connecting to the game network will allow your apps to talk to each other sending small data packets back and forth.

     http://imagineric.ericd.net/2011/04/20/ios-gamekit-iphone-to-iphone-communication/

     or you can use a TCP socket setup and communicate that way.

     If the ios devices are on the same network it can work from one to the other.

     If they are on other networks you will need a central server.

     If WCF meets your needs, it's worth looking at. ZeroC and other alternative higher level libraries exist. Otherwise there are several different ways to work closer to the socket level if that's what you need.

     TcpClient/UdpClient

     These provide a relatively thin wrapper around the underlying sockets. It essentially provides a Stream over the socket. You can use the async methods on the NetworkStream (BeginRead, etc.). I don't like this one as the wrapper doesn't provide that much and it tends to be a little more awkward than using the socket directly.

     Socket - Select

     This provides the classic Select technique for multiplexing multiple socket IO onto a single thread. Not recommended any longer.

     Socket - APM Style

     The Asynchronous Programming Model (AKA IAsyncResult, Begin/End Style) for sockets is the primary technique for using sockets asynchronously. And there are several variants. Essentially, you call an async method (e.g., BeginReceive) and do one of the following:

     • Poll for completion on the returned IAsyncResult (hardly used).
     • Use the WaitHandle from the IAsyncResult to wait for the method to complete.
     • Pass the BeginXXX method a callback method that will be executed when the method completes.

     The best way is #3 as it is the usually the most convenient. When in doubt, use this method.

     Some links:

     • MSDN Magazine Article on Sockets
     • A Jeffery Richter Article on the Asynchronous Programming Model

     .NET 3.5 High Performance Sockets

     .NET 3.5 introduced a new model for async sockets that uses events. It uses the "simplified" async model (e.g., Socket.SendAsync). Instead of giving a callback, you subscribe to an event for completion and instead of an IAsyncResult, you get SocketAsyncEventArgs. The idea is that you can reuse the SocketAsyncEventArgs and pre-allocate memory for socket IO. In high performance scenarios this can be much more efficient that using the APM style. In addition, if you do pre-allocate the memory, you get a stable memory footprint, reduced garbage collection, memory holes from pinning etc. Note that worrying about this should only be a consideration in the most high performance scenarios.

     • MSDN Magazine: Get Connected With The .NET Framework 3.5
     • MSDN Information with technique for pre-allocating memory

     Summary

     For most cases use the callback method of the APM style unless you prefer the style of the SocketAsyncEventArgs / Async method. If you've used CompletionPorts in WinSock, you should know that both of these methods use CompletionPorts under the hood.

   • Networking In EC2: VPCs, Subnets, And Route Tables

     Networking in Amazon EC2 involves several key components, including Virtual Private Clouds (VPCs), subnets, and route tables. These components are fundamental to creating isolated network environments for deploying and managing EC2 instances securely within the Amazon Web Services (AWS) cloud infrastructure. In Amazon Web Services (AWS), EC2 abbreviation is Elastic Compute Cloud one of the most popular service in AWS. In this article we will know By understanding and effectively configuring VPCs, subnets, and route tables, you can design and deploy network architectures in AWS that meet your specific requirements for security, availability, and performance. These networking components provide the foundation for building scalable and resilient cloud-based applications and services on the AWS platform.

     Amazon Elastic Compute Cloud (Amazon EC2) is a web service provided by Amazon Web Services (AWS) that allows users to rent virtual servers or virtual machines known as instances, on which they can run their own softwares and applications. An EC2 instance is essentially defined as virtual machine (VM) in the cloud.
