• Ubuntu inside VirtualBox is slow

  - by Kapsh

  I am running an Ubuntu instance on VirtualBox inside XP. Here are the details: Host: Windows XP Pro Guest: Ubuntu 8.10 Total RAM: 3GB RAM For VM: 1GB Total Video Memory: 128MB Video Memory for VM: 40MB Hard Drive: 200GB Hard Drive for VM: 30GB Processor: 2.80GHz Core Duo The problem is that whenever I am inside the virtual machine, things seem so much slower in general. For example Firefox, Eclipse take longer to load, dragging windows show a lag etc. I have tried running Ubuntu before (not inside a VM) and it seemed fantastically fast. So I am disappointed to have to deal with this situation. But I need access to the XP partition without having to reboot and hence the attempt. I am surprised with the perceived slowness since the whole world seems to be doing virtualization and I cannot imagine everyone works on slow systems knowingly. My question is - is there something I should be doing to boost performance? Am I doing something wrong? This is my home machine and I am not sure if this is the right forum to ask. Thanks.

• Odd SVN Checkout failures occur frequenctly on VMWare virtual machines

  - by snowballhg

  We've recently been experiencing seemingly random SVN checkout failures on our Hudson build system. Google search has failed me; I'm hoping the super user community can help me out :-) We are occasionally receiving the following SVN error when our Hudson build jobs checkout source via the Hudson Subversion plug-in (which uses svn kit): ERROR: Failed to check out http://server/svnroot/trunk org.tmatesoft.svn.core.SVNException: svn: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svnroot/!svn/vcc/default) svn: REPORT request failed on '/svnroot/!svn/vcc/default' This issue seems to only occur when checking out from our Virtual Machines (Windows XP, Fedora 9, Fedora 12) using Hudson's SVN Plug-in. Systems that use the traditional SVN client seem to work. SVN Server version: 1.6.6 Hudson version: 1.377 Hudson SVN Plugin Version: 1.17 Has anyone dealt with this issue, or have any suggestions? Thanks

• Wireless Disconnects Randomly, then won't reconnect

  - by Nironan12

  Okay, so I have a Gateway laptop, with Windows Vista SP2, and a Linksys-Cisco WRT54GL Wireless-G Broadband Router. When I boot up my laptop, it automatically connects itself to my home network. Then at random times, it disconnects itself from said network. I go to reconnect it, but I get an unknown error and none of Vista's suggestions are working. Sometimes, after 5-10 minutes, it will reconnect itself. I've already tried updating the firmware. I can't install any other firmware, or make a factory reset. My dad owns the router and buys the internet and he won't let me TOUCH it. I can't do ANYTHING to it.

• Multiple iSCSI Targets or 1 that's shared?

  - by Joost Verdaasdonk

  On my network I have several types of files I want to save on a SAN like: SQL db's and logs Exchange data Random files Now I'm wondering if I should create one iSCSI Target with a large volume and initiate that from one of the servers. (and share it so other servers can use it too) Or I should create separate Targets to have each server use its own storage. For the record the storage could be separated because the servers aren't using the shared data. For one reason I was thinking of one storage is ease of backup. (but perhaps performance could be a problem?) What would be an advisable configuration for these type of data?

• NAS device for distributed team

  - by user5959

  We are a distributed team spread across 5 locations. We have a shared drive (1 TB data) at our former location that we are currently accessing via Hamachi VPN. Our shared drive is a network folder on a Windows Server located at one of our locations. The current connection speed is terrible. The upload speed at the current location of the shared drive is very slow. We looking for a NAS device that we can host at another location with better upload speed that all of us can access. I am looking for a NAS device that has these features: Minimal Maintenance as we do not have dedicated IT resources Access data on the device from multiple locations. Ability to create network drive (On Windows Computers Map Network Drive) Upload data from random client computers without having to install software. (Right now, we use LogMeIn Rescue's file manager) Ability handle slow or dropped connections when transferring files (Maximum size 1.5 GB)

• Keyboard not responding on startup

  - by Mestika

  I’m having a weird problem with one of the laptops at my work. Every now and then (not a systematic repeating pattern, but kind of random) the keyboard will not function on start up. The computer boots and it gets to the CTRL + ALT + DELETE screen and it is responding to nothing from the keyboard. The mouse works fine. I then try to force a shutdown and reboot the machine and most of the time it then works. My first thought was that it was a hardware malfunction with the keyboard hardware but it seems strange that the computer can be stationed for several days without being removed and it still “loses” connection to the keyboard. The OS is Windows 7 Pro and it is a Dell Laptop Vostro. Does anyone experienced this kind of problem with a laptop with/with out Windows 7 and maybe got a solution to the problem?

• Can't resolve Mac's machine name on VPN

  - by Raghuveer

  My mac'c machine name is something like this: hostname.company.com but whenever I connect to VPN, it becomes something like vpn-xxxx.company.com where xxxx are some random numbers. Because of this, some of my scripts which are dependent on host name gets blocked. We use the standard mac's vpn setup which comes with OS X Lion (under network preferences). How can I resolve to the correct mac's name even if I am on vpn ? That is even if I am connected to VPN, my machine name should resolve to hostname.company.com and NOT to vpn-xxxx.company.com. Any suggestions would be really appreciated.

• computer reboots randomly, can't find ssd

  - by John Barry

  My comp's been restarting at random times, and when it comes back the SSD drive can't be found by the BIOS and it doesn't boot. Powering down and starting up again fixes it 90% of the time, with a second reboot occasionally required. Does not seem to be heat related; it's never happened with me actually on the computer. It has happened while acting as the squeezebox server, however. It's a Sandy-Bridge i7 arch if that helps. To add: I've also run Windows Memtest and it came back with no issues.

• Default Window Size and Positions

  - by muntoo

  I'm running Vista Home Premium 32-Bit, though I doubt that matters, in this case. So, how do you set the default windows size/positions? Is there a registry tweak for this? Going to Tools->Folder Options...->View Apply to Folders or Reset Folders doesn't work. So, whenever I open a new window to a random new folder I haven't opened before, I don't want it to take 75% of the screen. Is there any way I could make it open smaller? (So it opens correctly the first time.)

• Browser keeps being really rude to me today

  - by j-t-s

  Hi All I've had this problem only once before, years ago. I bought a new computer the other day and last night I visited a website which Google Chrome suspected was an insecure site. So I proceeded to view the page anyway (Stupid, I know... But I was curious), and all of a sudden the window closed and ever since, every few minutes either Google chrome or Internet Explorer keeps popping up with random websites, most of which are porn-related sites. I have downloaded ZoneAlarm, IOBit 360, Eset Smart Security and none of them reported any problems. I still have the rube browser problem. Can somebody please suggest any software/ways to fix this? (Other than to reformat please :)) Thank you :)

• Running game, leaving game and continuing animation

  - by Madrusec

  I have been trying to learn some Actionscript recently and have been trying to run an interactive story that at one point turns into an extremel simple shooter game. After the player either wins or looses, then he/she is taken to the rest of the animated story. So I have everything up to the point where the games runs (successfully) but for some reason I am unable to have flash run the rest of the frames, most of which have no code at all. This is the code for scene 1: stop (); import flash.display.MovieClip; import flash.events.MouseEvent; import flash.utils.Timer; import flash.events.TimerEvent; var stoneInGame:uint; var stoneMaker: Timer; var container_mc: MovieClip; var cursor:MovieClip; var score:int; var anxiety:int; var anxiety_mc :MovieClip = new mcAnxiety(); //stage.addChild( anxiety_mc ); function initializeGame():void { stoneInGame = 10; stoneMaker = new Timer(1000, stoneInGame); container_mc = new MovieClip(); addChild(container_mc); container_mc.addChild(anxiety_mc); anxiety_mc.x = 497; anxiety_mc.y = 360; stoneMaker.addEventListener(TimerEvent.TIMER, createStones); stoneMaker.start(); cursor = new Cursor(); addChild(cursor); cursor.enabled = false; Mouse.hide(); stage.addEventListener(MouseEvent.MOUSE_MOVE, dragCursor); score = 0; anxiety = anxiety_mc.totalFrames; anxiety_mc.gotoAndStop(anxiety); } function dragCursor(event:MouseEvent):void { cursor.x = this.mouseX; cursor.y = this.mouseY; } function createStones(event:TimerEvent):void { var stone:MovieClip; stone = new Stone(); stone.x = Math.random() * stage.stageWidth; stone.y = Math.random() * stage.stageHeight; container_mc.addChild(stone); } function increaseScore():void { score ++; if(score >= stoneInGame) { dragCursor.stop(); createStones.stop(); stoneMaker.stop(); trace("you wind!"); } } function decreaseAnxiety():void { anxiety--; if(anxiety <= 0) { stoneMaker.stop(); trace("you lose!"); } else { anxiety_mc.gotoAndStop(anxiety); } increaseScore(); } initializeGame(); So what I tried to do was adding gotoAndPlay() inside both the decreaseAnxiety and increaseScore functions after the trace statements and referenced a frame where I have more keyframes that continue a story. However, Flash just goes back to the beginning of the timeline and I even the functions that change and control the cursor seem to be running. This leads me to believe that I need to make sure that I tell flash o stup running certain functions before jumping to another frame. However, it seems to me that I would still have the same issue and not be able to continue in the timeline. Is there something I am missing? How can I jump out of all this code once the game finishes and simply continue playing the rest of the frames? Any pointers would be greatly appreciated. Thank you

• Outlook 2010 and Exchange 2003

  - by user69644

  We've had some issues with a user who has upgraded to Outlook 2010 and attached to an internal Exchange 2003 SP2 server. They get errors more or less saying cannot send, contact your administrator and then a long error string whenever attempting to send. They receive just fine - but can't get any outbound flow. We recreate the users profile on another Windows 7 machine with Outlook 2010 and it worked fine. Concerned this might be an issue that rears it's ugly head later or at some random time. We noted some KB docs about the issue recommending registry changes - we've reviewed and ensure these changes were made and still have the issue on the one machine. Any thoughts?

• Store system passwords with easy and secure access

  - by CodeShining

  I'm having to handle several VPS/services and I always set passwords to be different and random. What kind of storage do you suggest to keep these passwords safe and let me access them easily? These passwords are used for services like databases, webserver user and so on that run customers' services, so it's really important to keep them in a safe place and strong. I'm actually storing them in a google drive spreadsheet file, describing user, password, role, service. Do you know of better solutions? I'd like to keep them on a remote service to make sure I don't have to make backup copies (in case my hdd would fail somehow). I do work on *nix platforms (so windows specific solutions are not a choice here).

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Unidentified Window OnStartup

  - by CMP

  Every time I start up windows vista lately, I see a random floating window. It is a tiny little window with no title, and only the resize, maximize and restore buttons. I'd post an image, but I don't have reputation here yet. I can close it, and it does indeed go away, but I would love to figure out what it is and stop it from popping up at all. I used Autohotkey's window spy on it and all I learned is that it is a swing window, which doesn't help me out a whole lot. Is there a good way to identify which process it belongs to and figure out how to kill it?

• SUSE linux nginx and phpmyadmin 404 errors

  - by user968808

  I've installed nginx and phpmyadmin etc and most things work fine. I'm getting random problems though... e.g. when I click drop I get a message on the screen to say its updating and then the page does not refresh afterwards. Also randomly get 404 errors if I check all when trying to delete rows out of a database. Or if I import a file over around 10-20 rows i get 404 page not found. Where have I gone wrong?

• How is a nameserver chosen when DNS resolution occurs?

  - by Richard

  I have a few domains hosted on nameservers at Zerigo. Zerigo have 5 nameservers and I have all 5 in the nameserver records for my domains. The nameservers are in different geographical locations (3 in the US, one in London, and one in Amsterdam). When someone goes to a domain of mine and the DNS resolution occurs, how will it choose a nameserver? Will it always go to the nearest geographical one? Will it go to the one with fewest hops? Will it just choose one at random? (This is assuming all 5 are functioning perfectly). Thanks EDIT: And does it make any difference which order I list the nameservers in on the domain name records?

• How to troubleshoot Application Popup issues 0XC0000142 and 0XC000009a

  - by DotDot

  I am running randomly into 1 of these popups when our application runs. The machines range from 8GB/8Core to 24GB/24Core and run Windows Server 2008 R2. The application is a bunch of perl scripts and exe's that are expected to utilitize the server well. The process tree can be quite deep (5-6 child levels) and quite broad (60-70 level 1 processes). We hit this issues every 1% run on random machines. The application stalls on popup, unless someone clicks the damn button. The event log reads as cmd.exe - "Failed to initialize app. Click OK to close app" How could I reliably repro these issues?

• What is the easiest way to apply database functionality into my daily life?

  - by Daddy Warbox

  let me try to explain it by listing some of the things I want to do: Submit random thoughts, notes, facts, and to-do tasks of any sort and at any time. Tag each of these submissions freely. Manage these tags centrally. Associate meta-data with submissions and tags. Search, filter, and sort submissions. I want lots of power here. Display views of submissions (including within searches) in a hierarchy. Create said hierarchies easily out by ordering relevant tags. I'm thinking towards some kind of desktop program that allows me to quickly do all of these things. A web service could also work, too, but it will need offline capabilities. I don't want to have to pay for this, if that's possible. Also, as I know regex and SQL, I wouldn't mind solutions involving the use of either.

• Stopped windows firewall service during ICS, how is this possible?

  - by insipid

  Although windows firewall is required to be on when you "start" Internet Connection Sharing, you can stop the WF service with MMC. When done a client can still use the host machines internet. The firewall had port 80/http blocked, and now it is open for incoming traffic. However other ports used by applications on the host and client which communicate with each other still seem to be blocked. Can anybody explain what might be happening here? Doesn't ICS need windows firewall for NAT? Note: I am not actually seeing anything in the firewall logs after stopping the service, but even packets sent localhost on the host machine never arriving on these other random ports.

• How to set up VPN connection? Virtual Box 3.1.4 installed. Host - Snow Leopard(Mac) Guest - Windows 7 (32-bit)

  - by user31954

  I have Virtual Box 3.1.4 installed. Host - Snow Leopard(Mac) Guest - Windows 7 (32-bit). I have installed Windows on my MAC because I need it for work. I cannot establish VPN connection (using NAT). I tried to use bridged adapter, and I lost my internet connection on my guest(wind7) completely. I don't know much about networking, so I need detailed instructions for his particular OSs. Could someone please help me with this? Some random details about my attempts: On my host Windows I get error 800 trying to VPN. I can ping server address from my guest Win 7 and I have VPN connection established from my host Mac. I do disable VPN on my Mac when tying to establish it through guest. I tried to VPN from Mac and see if Guest sees it. It doesn't. Thank you!

• Are these hardwares compatible?

  - by Tom Kaufmann

  I am trying to upgrade my new machine but I want to do it myself. This is my 1st attempt at building system.

• Understanding IUSR_<machine> account

  - by liho1eye

  Namely how is setting read/write permission for this account different from giving read/write access in the IIS (Windows 2003, so it should be IIS6 if I am not mistaken). Here is the issue: It looks like we had a security sweep and as a part of that IUSR account lost write access everywhere. A whole bunch of legacy ASP sites didn't like that at all... My very surfacish understanding is that it is enough to deny write access in the IIS console to protect a website from someone just dropping random files into it, and IUSR access only has effect on the application scripts running server side, and thus can be safely given write access back. edit: The applications in question obviously require write access to their own web folders, otherwise this wouldn't be an issue at all. Question is how to configure IIS/application to both satisfy security and make them work. My first instinct was to change account which is used to run the app pool. However that is already set to NETWORK_SERVICE, and that guy already has full access to folders in question.

• Windows 7 64bit keyboard issues

  - by Scott

  I have a Pavilion dv4 notebook running Windows 7 64bit Enterprise edition. This morning I started to notice some really strange behavior in how it handled its built-in keyboard. At random intervals there will be a long delay in key presses, to which some keys will never show and other keys will continue to repeat until you hit the backspace. Other keys get mapped incorrectly to other keys. If I hook up an external keyboard the problem does not appear. Before I reformat the machine and do a fresh install, I thought I would check here to see if anyone has experienced this same issue and if so, how did you fix it?
