I'm using a TcpClient passed to me from a TcpListener, and for the life of me I can't figure out a simple way to get the address and port it's connected to. The best I have so far is _client.Client.RemoteEndPoint.ToString(); which returns a string in the form FFFF::FFFF:FFFF:FFF:FFFF%00:0000. I've managed to extract the address and port...
That's odd, TBaseSocket's WaitForData documentation specifies that you should call it before SendBuf and Sendln calls. I had a quick try and (perhaps because I trying to write first) this WaitForData call returns false. (after timing out the specified timeout) So is this incorrect? Or incomplete?

Hi, I have an ASP.NET application which talks to a third-party SOAP web service. My application uses an ASMX client proxy (i.e. System.Web.Services.Protocols.SoapHttpClientProtocol). The third-party service uses WCF, although I don't expect that makes much difference. I should note that we're using .NET 3.5 SP1. We haven't customised ...
I am about to write a tcp/ip data relay - application that passes a one way stream of data from one host/port to another host/port. Initially it will be generic, but later on i will customize it to the need of a specific business request. I am guessing that something generic already exists out there so my question is: Has anyone used a...

However I couldn't find a way to do this in .NET Framework 3.5. To be more s...
What I'm currently trying to do is make a very basic webchat for irc using silverlight. Basically how I'm trying to do it is have a tcp server listening for connections from silverlight. When a client connects it creates a new connection to irc and data is passed to/from the client/irc via the server application. I've gotten it to work...

Hello! I'm wondering how to limit the TCP requests per client (per specific IP) in Java. For example, I would like to allow a maximum of X requests per Y seconds for each client IP. I thought of using static Timer/TimerTask in combination with a HashSet of temporary restricted IPs. private static final Set<InetAddress> restrictedIPs = ...

I have an application with fairly high traffic (20K req/min) running on the JVM with a Jetty servlet container on Ubuntu. Below is my Jetty configuration: 10 20 2000 2 When I analyze the network traffic, I realize that sometimes it is taking long to establish TCP connections on the port that Jetty is runn...
Hi there, I have something like a proxy server (written in java) running between my clients and the actual video server (made in c++). Everything the clients send goes through this proxy and is then redirected to the server. It is working fine, but I have some issues and think it would be better if I could make this proxy server only to...
