  • Is there a way to forward emails associated with a domain without a mail server?

    - by MeltingDog
    A client owns example1.com but wants to also purchase example2.com and have it point to their original site at example1.com. No problem there. But they also want any emails going to example2.com to be forwarded to their counter parts at example1.com Eg: if someone emails [email protected] it will be forwarded to [email protected] They only way I can think of doing this at the moment is to set up host for example2.com and then set up mail forwarders in cpanel. But this seems a bit excessive and costly. Does anyone know another, cheaper way of doing this?

  • Why the SQL Server FORCESCAN hint exists

    It is often generalized that seeks are better than scans in terms of retrieving data from SQL Server. The index hint FORCESCAN was recently introduced so that you could coerce the optimizer to perform a scan instead of a seek. Which might lead you to wonder: Why would I ever want a scan instead of a seek? 12 must-have SQL Server toolsThe award-winning SQL Developer Bundle contains 10 tools for faster, simpler SQL Server development.

  • How to split currently used partition on Ubuntu server?

    - by KrizzzyS
    I would like to split a currently used partition that is mounted to /usr directory. I did this because / only had 1 gb of data allocated to it. Now, I did not account for the /home directory when I made this partition (or I would have made two partitions). So I have 14 gb mounted to usr/ with 12 gb free. Is there a way I can reclaim the free space on this partition to make another partition to mount to /home? Here is the result of a df -h: I have tried to split the /dev/mmcblk1p4 into 2 different partitions but I was not able to save the partition table correctly.

  • fork() in perl on windows

    - by Darioush
    I'm using fork() on PERL in windows (activeperl) for a basic socket server, but apparently there are problems (it won't accept connections after a few times), is there any workaround? while($client = $bind->accept()) { $client->autoflush(); if(fork()){ $client->close(); } else { $bind->close(); new_client($client); exit(); } } is the portion of the relevant code.

  • Java multithreaded server - each connection returns data. Processing on main thread?

    - by oliwr
    I am writing a client with an integrated server that should wait indefinitely for new connections - and handle each on a Thread. I want to process the received byte array in a system wide available message handler on the main thread. However, currently the processing is obviously done on the client thread. I've looked at Futures, submit() of ExecutorService, but as I create my Client-Connections within the Server, the data would be returned to the Server thread. How can I return it from there onto the main thread (in a synchronized packet store maybe?) to process it without blocking the server? My current implementation looks like this: public class Server extends Thread { private int port; private ExecutorService threadPool; public Server(int port) { this.port = port; // 50 simultaneous connections threadPool = Executors.newFixedThreadPool(50); } public void run() { try{ ServerSocket listener = new ServerSocket(this.port); System.out.println("Listening on Port " + this.port); Socket connection; while(true){ try { connection = listener.accept(); System.out.println("Accepted client " + connection.getInetAddress()); connection.setSoTimeout(4000); ClientHandler conn_c= new ClientHandler(connection); threadPool.execute(conn_c); } catch (IOException e) { System.out.println("IOException on connection: " + e); } } } catch (IOException e) { System.out.println("IOException on socket listen: " + e); e.printStackTrace(); threadPool.shutdown(); } } } class ClientHandler implements Runnable { private Socket connection; ClientHandler(Socket connection) { this.connection=connection; } @Override public void run() { try { // Read data from the InputStream, buffered int count; byte[] buffer = new byte[8192]; InputStream is = connection.getInputStream(); ByteArrayOutputStream out = new ByteArrayOutputStream(); // While there is data in the stream, read it while ((count = is.read(buffer)) > 0) { out.write(buffer, 0, count); } is.close(); out.close(); System.out.println("Disconnect client " + connection.getInetAddress()); connection.close(); // handle the received data MessageHandler.handle(out.toByteArray()); } catch (IOException e) { System.out.println("IOException on socket read: " + e); e.printStackTrace(); } return; } }

  • Is is possible to use IOCP (or other API) in reactor stle operations?

    - by Artyom
    Hello, Is there any scalable Win32 API (like IOCP not like select) that gives you reactor style operations on sockets? AFAIK IOCP allows you to receive notification on completed operations like data read or written (proactor) but I'm looking for reactor style of operations: I need to get notification when the socket is readable or writable (reactor). Something similar to epoll, kqueue, /dev/poll ? Is there such API in Win32? If so where can I find a manual on it?
