  • Mysql too many connections but not visible in fullprocess list

    - by user968898
    I got a big problem, I guess it's something like a dos attack but I am not sure. Since this morning, my database is very slow and gives me 7/10 times a too many connections error or tries to login with www-data user (as following up of the too many connections error?). I tried to locate the issue by mysql command line with 'show fullprocess list' but it gives me just one response back and that 'me'. What can I do about this? The websites are still running ok, but mysql is overused I guess.

  • SSH very slow when connecting from external [closed]

    - by wnstnsmth
    Possible Duplicate: ssh delay when connecting We have a CentOS server that we use for internal testing purposes, which has sshd enabled. When I (as a developer) am at the company, I use ssh [email protected] to connect to it - and it works flawlessly. Now, in order to work from home, accessing the server via the company's static IP, we set up another port for ssh, 2020. So I execute ssh -p 2020 [email protected] and am immediately granted for a password. After entering the password, it takes up to 30 seconds until I can access the server. Same is with SFTP (i.e. uploading files takes about 30 seconds until it begins to transfer). As you can imagine, if you have to regularly upload files to a webserver via SFTP, this is very tedious. So I looked at similar questions and thus edited the sshd_config file on the server, setting UseDNS to "no" and GSSAPIAuthentication to "no" (this one also in ssh_config on the client) - it did not work.. Please have a look at the -vvv output when externally accessing the server: ssh -p 2020 -vvv [email protected] PasteBin: ssh What could it be? Do you need more info?

  • Connections to Cotendo CDN servers are unreliable

    - by user139050
    I've been having a lot of trouble viewing certain websites - Gawker Media, DeviantArt, etc. - and through further investigation they all appear to be using a CDN called Cotendo. On my machine, and only this one, connections reset themselves midway through the download most of the time. This is not browser-specific; even wget (Cygwin) is unable to download anything without retrying a few times. This happens inside virtual machines as well. Unfortunately, I'm pretty stumped on why this is happening. My hosts file is empty (except for a couple LAN-specific things) and I've checked a few different DNS servers, but I can't really think of anything else to try. Anyone have any ideas?

  • Fastest sorting algorithm for a specific situation

    - by luvieere
    What is the fastest sorting algorithm for a large number (tens of thousands) of groups of 9 positive double precision values, where each group must be sorted individually? So it's got to sort fast a small number of possibly repeated double precision values, many times in a row. The values are in the [0..1] interval. I don't care about space complexity or stability, just about speed.

  • 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 C# fast enough for games

    - by Matt
    Will a game written in C# have any speed issues after long periods of play, like for 24 hours at a time? I'm specifically talking about a 2D RPG similar to old Final Fantasy or Dragon Quest games. I know that languages like Python will slow down too much, curious how C# would stand.

  • R or Python for file manipulation

    - by danspants
    I have 4 reasonably complex r scripts that are used to manipulate csv and xml files. These were created by another department where they work exclusively in r. My understanding is that while r is very fast when dealing with data, it's not really optimised for file manipulation. Can I expect to get significant speed increases by converting these scripts to python? Or is this something of a waste of time?

  • Linux USB debug connection to LuminaryMicro evaluation board

    - by mikelong
    Hi, I am trying to connect a Stellaris LM3S8962 evaluation kit to a linux host machine. I am using the CodeSourcery G++ for the development toolchain. When I try to run a helloworld example the connection fails with this message: arm-stellaris-eabi-sprite: error: E104. I/O Error communicating with USB Device. arm-stellaris-eabi-sprite: waiting for GDB connection, to pass error along warning: Remote failure reply: E.fatal.E104.

  • Router reconfigures PC's and they can no longer access the internet via hardwired connection to DSL Modem

    - by zchads
    Router reconfigures PC's and they can no longer access the internet via hardwired connection to DSL Modem. Hardware Information: Buffalo Wireless Router/access point, Model: WZR-HP-G300NH-AP DSL Modem: Generic (actually not sure of manufacture). Service Provider: TOT (Thailand) Laptop-1: Windows XP and Belkin PCMIA Network Card Laptop-2: Windows XP unknown network card & Wifi Laptop-3: Windows 7 unknown network card & Wifi Outline of Problem/actions taken: After a recent power failure the router and laptop-1 connected to router were no longer able to access the internet. Actions taken to try and recover internet access: Using Laptop-1 tried to configure Router with PPPoe settings using software from Router Manufacture. During the installation process a Timeout error was experienced, unable to connect to WAN. Used Internet Explorer to communicate directly with Router using IP address. Changed settings to use PPPoe settings given by ISP. Router was not able to communicate with Internet. Repeated steps 1-4 again with no success. Reset Router and DSL modem. Repeated steps 1-4 again still no success. Tried connecting Laptop-1 directly to DSL to gain access to internet to research problem. No Network connection with DSL could be established…connection would be established for a second and then be lost and didn’t appear long enough to actually connect to DSL. Replugged LAN back into Router and connection was regained with laptop-1. Replugged Laptop-1 directly into DSL and again unable to establish network connection. Uninstalled network card and all of its drivers on Laptop-1. Reinstalled network card and drivers and tried connecting directly to DSL. Still unable to make network connection. Plugged DSL into Laptop-3 and Internet connection was established. Being Laptop-3 does not have a CD-Rom, Laptop-2 was tried to connect to the router. With Laptop-2 steps 1-7 ended up being repeated without success. Tried plugging Laptop-2 directly into DSL and again no network connection could be established. Using Laptop-3 with a direct connection to DSL downloaded latest Router FW. Installed router FW using Laptop-1. Tired the installation process again without success. Being desperate reinstalled OS on Laptop-1 still not success. Tried using “ipconfig” with router to see what was going on without success. With laptop-1 connected to DSL went through the “ipconfig /…” inputs to see if anything made a difference. Being the network card was not able to make a connection this provide very little information “media disconnected”. So now I have a router and two laptops which are unable to connect to the internet and sure could use some advice/help.

  • When and how often to start connection to database in php?

    - by AndHeiberg
    When and how often is it good practice to start the connection to your database in php? I'm new to databases, and I'm wondering when I should start by database connection. I'm creating a api with an index, controllers and model. Should I start the connection in the index and then pass it to all the other files, start the connection at the top of all files and call it as a global in functions as needed or start and end the connection in every function?

  • How to update all the SSIS packages&rsquo; Connection Managers in a BIDS project with PowerShell

    - by Luca Zavarella
    During the development of a BI solution, we all know that 80% of the time is spent during the ETL (Extract, Transform, Load) phase. If you use the BI Stack Tool provided by Microsoft SQL Server, this step is accomplished by the development of n Integration Services (SSIS) packages. In general, the number of packages made ??in the ETL phase for a non-trivial solution of BI is quite significant. An SSIS package, therefore, extracts data from a source, it "hammers" :) the data and then transfers it to a specific destination. Very often it happens that the connection to the source data is the same for all packages. Using Integration Services, this results in having the same Connection Manager (perhaps with the same name) for all packages: The source data of my BI solution comes from an Helper database (HLP), then, for each package tha import this data, I have the HLP Connection Manager (the use of a Shared Data Source is not recommended, because the Connection String is wired and therefore you have to open the SSIS project and use the proper wizard change it...). In order to change the HLP Connection String at runtime, we could use the Package Configuration, or we could run our packages with DTLoggedExec by Davide Mauri (a must-have if you are developing with SQL Server 2005/2008). But my need was to change all the HLP connections in all packages within the SSIS Visual Studio project, because I had to version them through Team Foundation Server (TFS). A good scribe with a lot of patience should have changed by hand all the connections by double-clicking the HLP Connection Manager of each package, and then changing the referenced server/database: Not being endowed with such virtues :) I took just a little of time to write a small script in PowerShell, using the fact that a SSIS package (a .dtsx file) is nothing but an xml file, and therefore can be changed quite easily. I'm not a guru of PowerShell, but I managed more or less to put together the following lines of code: $LeftDelimiterString = "Initial Catalog=" $RightDelimiterString = ";Provider=" $ToBeReplacedString = "AstarteToBeReplaced" $ReplacingString = "AstarteReplacing" $MainFolder = "C:\MySSISPackagesFolder" $files = get-childitem "$MainFolder" *.dtsx `       | Where-Object {!($_.PSIsContainer)} foreach ($file in $files) {       (Get-Content $file.FullName) `             | % {$_ -replace "($LeftDelimiterString)($ToBeReplacedString)($RightDelimiterString)", "`$1$ReplacingString`$3"} ` | Set-Content $file.FullName; } The script above just opens any SSIS package (.dtsx) in the supplied folder, then for each of them goes in search of the following text: Initial Catalog=AstarteToBeReplaced;Provider= and it replaces the text found with this: Initial Catalog=AstarteReplacing;Provider= I don’t enter into the details of each cmdlet used. I leave the reader to search for these details. Alternatively, you can use a specific object model exposed in some .NET assemblies provided by Integration Services, or you can use the Pacman utility: Enjoy! :) P.S. Using TFS as versioning system, before running the script I checked out the packages and, after the script executed succesfully, I checked in them.

  • Why, when on Kubuntu I lose internet connection, am I unable to reconnect?

    - by Jonathan
    Using Kubuntu 11.10. Sony Vaio computer. Network controller: Intel Corporation WiFi Link 5100. If I connect to a wireless network, and the signal drops, then I am unable to connect to any network without a reboot. I can assure that the issue has nothing to do with the computer going to sleep, as I have experienced the above while using my computer continuously. Here is exactly what happens: Connect to network (at University, where the connection is not so great). The connection is broken There are three other possible networks available, but none of them can be connected to. I have tried off and on sometimes for hours. I am always able to reestablish a connection after a reboot. I can only think of two explanations. The first is that a temp file is corrupted when the internet connection is abruptly dropped. The second is that my computer actually corrupts something before the loss of internet connection, which causes the loss in signal, and inability to reconnect. However, I am not confident that my explanations are complete, nor do I have any idea how to test these things.

    - by krasilich
    I have Broadcom bcm43224 wifi card with proprietary broadcom sta driver. At home wifi connection works well, but in the office when I ping some resource there is a lot of loss packets and I cant browse websites. I have tried another way to check internet connection - download file with wget. wget google.com - very slow speed wget -4 google.com - normal speed So, it seems that the problem is with the ipv6 configuration at the office, can I force my wifi connection to use only ipv4 and completely ignore ipv6 ?.

  • netbeans 6.8 php, xdebug, mamp - cannot establish a connection

    - by Mike
    I'm having no luck whatsoever with debuggers either on Zend Studio or NetBeans. I cannot believe the difficulty I'm having with these IDE's. I've read all the prior questions on netbeans-xdebug problems. According to those answers, my configuration is correct. Nonetheless, when I try to run xdebug, NetBeans hangs. I cancel the connection and get the popup dialog: "There is no connection, blah blah blah..." Here's my php.ini [xdebug] ; Xdebug config for Mac OS X and NetBeans IDE zend_extension=/Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so xdebug.remote_enable=on xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000 xdebug.idekey=netbeans-xdebug In NetBeans preferences, my session ID = netbeans-xdebug. I tried xdebug.idekey="netbeans-xdebug" That made no difference. I restarted the web server every time. Anyone have any other suggestions I might try? Thanks.

  • VBA ActiveX controls grow in size over Remote Desktop Connection

    - by Alistair Knock
    We have an Excel workbook with a number of ActiveX controls, running in Excel 2003 on Windows XP. When connecting using Remote Desktop, the ActiveX controls change font, sometimes font size, and sometimes orientation (in the case of a spinner control). This happens on first connection and also as the workbook is used - some of the controls then enlarge in size, often overlapping other controls and part of the workbook. I read somewhere this may be caused by improper connection management (not closing them) leading to increasing memory usage; are there other reasons why the display is so different over Remote Desktop and are there workarounds? (the properties of each control usually remain the same, so force-resizing them doesn't always have an effect)
