I've got heartbeat threads on both ends which are sending keepalive-packets on application level successfully. The problem is that after a while (varies between 5-20min) the phone is starting to send TCP keepalives to the server, which t...

There is a flash movie which is using flash.net.Socket to connect to a server. But there could be a situation when the server is not running, hence nothing is listening on the port socket is connecting to. When I do "telnet hostname port" I get a fast connection refused error.

Hi - I am trying to create a client-server application with XML-RPC in Python, in Ubuntu Linux. It is straightforward to have the client side request a particular service from the server side. What I am trying to do is have the client send a file to the server. The server will then process the file; this process may take a few hours. W...
I need to serve a file on localhost to a certain application which only accepts http URI-s. However, the files are generated on the fly and I would like to avoid writing to disk, so I decided to write a simple HTTP server using QTcpServer. Luckily, I even found a nice tutorial explaining just that. However, I'm not familiar with HTTP res...

I've got an event-driven network server program. This program accepts connections from other processes on other hosts. There may be many short-lived connections from different ports on the same remote IP. Currently, I've got a while(1) loop which calls accept() and then spawns a thread to process the new connection. Each connection i...
Another problem with mantaray: We have "a lot" of PCs in a network, our p2p messaging software uses MantaRay (which we plan to replace with something else). On some PCs the task manager shows CPU at 100% when this application runs. We tried to investigate that with TCPView, and found that these PCs open more than one TCP connection from...
