  • Varnish / Apache redirecting to backend port 8080

    - by deko
    I'm running Varnish 2 with Apache backend at 8080 on the same machine. Everything is working fine, except one problem: Sometimes Apache(?) is redirecting to backend port :8080 especially when I'm using htaccess. Users are displayed the 8080 port in the URL and Google is crawling my site on the backend port as well, which is not desirable. I want Apache 8080 to be accessible only to Varnish on localhost, and not to redirect or display the backend port. What would be a quick way to prevent users being directed to 8080 and search engines denied crawling the backend? Here is an example htaccess line: redirect /promotion /register.php?promotion=june which causes www.domain.com/promotion to redirect to www.domain.com:8080/register.php?promotion=june

  • What's Your Favorite Harmless Computer Practical Joke?

    - by Ben Griswold
    A couple of months ago, I returned from lunch to find that typing any key launched a random application. As I always lock my machine before walking away from it, my first thought was that a co-worker was playing a practical joke on me. As it turned out, the cause was random computer wonkiness. But just in case there's a need :), what's your favorite harmless computer practical joke? For example, would you alter host file entries to direct google.com to a random site or would you put tape over the optical sensor of a co-worker’s mouse?

  • Can Resource Governor for SQL Server 2008 be scripted?

    - by blueberryfields
    I'm looking for a method to, in real-time, automatically, adjust Resource Governor settings. Here's an example: Imagine that I have 10 applications, each hitting a different database on the same database machine. For normal operations, they do not hit the database very hard, so I might want each one to have 10% CPU power reserved. Occasionally, though, one or two of them might spike, and run an operation which could really use the extra power to run faster. I'd like to be able to adjust to compensate (say, reducing the non-spiking apps to 3%, and splitting the difference between the spiking apps). This is a kind of poor man's method of trying to dynamically adjust resource allocation and priorities. Scripts (or something script-like) is preferred, since the requirement is for meta-level adjustments to be possible in real-time, also.

  • How do you manage perl modules on a Debian system?

    - by nagul
    I'd like to know if you have a method for managing perl modules on your Debian system, with respect to the following: Installing new modules Listing of manually installed modules Checking dependencies, and uninstalling modules I have looked at this perlmonks article for background reading: What is the best way to install CPAN modules on Debian? I have previously installed perl modules using the CPAN module. I have also used dh-make-perl in some cases, when following instructions to build other packages that had perl dependencies. I'd like to institute a coherent policy on my machine so I can better manage how and where the modules are installed, and reduce the chance of breaking perl on my system. I would strongly like a system where I can detect and uninstall modules that are no longer being used.

  • Getting error 0x000003eb when installing DDK sample printer drivers

    - by Andy
    I've got a development machine, which has been severly abused when it comes to installing and removing printer drivers. I'm now at the stage where I want to install some sample printer drivers from the DDK (WDK), but unfortunately I get the message 'Unable to install printer. Operation could not be completed (error 0x000003eb). So I tried installing the same printer driver built from the DDK in a clean Win 7 x64 VM, and it works, so the only thing I can imagine is that the driver store or driver folder may be slightly corrupt from the many previous printer drivers I had installed. So my question is, is there anyway I can clean my system of old printer drivers / file? Or any repair functionality in windows that may replace the common windows printer drivers?

  • Windows 7: Open File - Security Warning box appears for every app on the desktop

    - by Michael Ratanapintha
    Whenever I double-click to open an executable on the desktop (.exe, .bat, etc.), or a shortcut on the desktop that points to an executable, the "Security Warning" pops up and asks me "Are you really sure you want to open that? Stuff from the Internet is dangerous!" I don't usually mind this warning and don't want to disable it globally, but now I'm getting it for any executable on the desktop, even ones that I didn't download from the Web and don't have the Mark of the Web alternate data stream. (That is, streams -d * shouldn't and doesn't help.) This started fairly recently, but I can't really point to anything I did that triggered it. It only occurs in one user account on the machine; the other account doesn't have this problem. Running System Restore didn't help. How can I fix the problem and make the pop-up warning appear only when it's supposed to?

  • Make Network Manager use bridge for PPPoE instead of only working on ethernet?

    - by Azendale
    My ISP uses PPPoE on their DSL connections. I use Network Manager to connect to this using a bridged modem connected to eth0. Often, I want to test networking things, so a set myself up a KVM machine with a tap interface. I can then connect these interfaces to to virtual 'switches' by adding them to bridges. (I work for my ISP). Sometimes, I want to test cases where the PPPoE is connected more than once. For this, I would like to be able to add eth0 to my 'switch' (a bridge) so the VMs can have a 'bridged modem' connection to the internet. But I would like to still be able to run the PPPoE for my computer at the same time. Which means that I need to get network-manager to run PPPoE over the bridge (or eth0). The problem is that it considers eth0 (and the bridge) 'not managed' by network manager, so it refuses to use it. So, how can I have network manager dial PPPoE over a bridge?

  • sysprep failure on Windows Server 2008

    - by dushyantp
    Before deploying a Azure VM Role, we need to perform %windir%\system32\sysprep\sysprep.exe /generalize /oobe /shutdown But in my case the sysprep fails with the log file %windir%\system32\sysprep\Panther\setuperr.txt saying: 2012-07-05 08:03:57, Error [0x0f0073] SYSPRP RunExternalDlls:Not running DLLs; either the machine is in an invalid state or we couldn't update the recorded state, dwRet = 31 2012-07-05 08:03:57, Error [0x0f00ae] SYSPRP WinMain:Hit failure while processing sysprep cleanup external providers; hr = 0x8007001f I do not always want to create a new image. Is there any work around? I followed the instructions in MS support here and tried: %windir%\system32\sysprep\sysprep.exe /generalize /oobe /shutdown /unattend:.\unattend.xml It did not work. Under certain circumstances, I need to tear down the VM Image from azure and re-deploy with some more changes. So sysprep has to run almost twice every week.

  • Visual Studio 2005 Open Project Dialog Slow as Molasses

    - by futureelite7
    Hi, Whenever I try to open a project in Visual Studio 2005 (Windows XP), my open project dialog become slow as molasses - navigating down one level of folders typically takes almost 60 seconds. Finding the project and opening it can take up 4-5 minutes, which is just ridiculous. I've checked the open project dialogs of other programs - only VS2005 is acting this way. What could be causing this problem and how do I go about solving it (apart from reinstalling VS2005 / windows) (Edit: Even VS2008 on the same machine does not have this problem. I don't know what's wrong.) Thanks!

  • Not able to connect to perforce server outside of localhost

    - by bobber205
    My setup is a Qwest PK5000 router with a Linksys router running Tomato. I have DMZ pointed towards my router. (The server is on the tomato router). I tried my applications that open up sockets and Utorrent (port 6883) and I ended having to do advanced port forwarding and forward specific ports in addition to having DMZ on my router. The problem is that I cannot connect to perforce when on another machine on the LAN or off. Any ideas? :) Thanks!

  • Burning Xvid and Dvix Files problems

    - by chobo2
    Hi I am using windows 7 ultimate 64 bit edition and Nero 8. Recently I noticed that every time I go to nero and burn a dvix/xvid file as a data DVD and try to play it in a dvd player that supports these types it does not load up and play. I then go to my XP machine with Nero 6 on it and burn the exact same file as a data DVD and it works in the exact same dvd player. I am not sure why this is happening? I am not sure if it is windows 7, nero 8 or my actual dvd burner that is the problem. How should I go about and figure out what the problem is? Thanks

  • Cloning (mirroring) laptop display to area of external monitor display

    - by intuited
    I'm using Maverick "10.10" Meercat on a HP Pavilion tx2110. This machine has an NVidia Go6150 graphics card, and sports a 1280x800 display. I have an external monitor which can do 1280x1024 resolution. FWIW I'm using openbox as my window manager; as I understand it this shouldn't be a factor. I'd like to clone the display to the monitor, so that the size of the desktop remains at 1280x800, and there is a horizontal blank area on the external monitor. I.E. I want to avoid having to pan the display of the desktop on either monitor. So the actual resolution of the monitor would be 1280x1024, but the resolution of the section of the monitor where stuff was actually being displayed would be 1280x800. Using the nvidia-settings applet, I'm able to set up the cloned display so that the desktop size is 1280x1024 (the resolution of the external monitor), but can't find a way to instead have the desktop size stay at the resolution of the laptop's built-in display. Is this achievable? Ideally I'd like the external monitor's blank area to be at the top of the screen, i.e. for it to align the display with the bottom of the screen.

  • MacBook Pro for Windows development via virtualization. Performance?

    - by webworm
    I am a Windows/Web developer by profession and I have been considering a MacBook Pro as a replacement for my current development machine. I am impressed by the build quality, the uni-body construction and performance specs of the MacBook Pro. I am specifically interested in the 13.3" MacBook Pro running Core 2 Duo 2.4 GHz processor with 4 GB RAM. What I am wondering is this ... what performance can I expect running SQL Server 2008, IIS, and Visual Studio 2010 within a virtual environment (VMWare Fusion and Windows 7) on the above mentioned MacBook Pro? I like the 13.3" model as the size is more portable, but am I expecting to much from a core 2 duo processor? Would I need to look at the next step up in MacBook Pro using the core i5 processor? Thanks!

  • Monitoring CPU Usage Over the Course of a Day?

    - by bobber205
    Are there any apps I an install on client machines that will generate a report for me what app used what % of the CPU. We have some machines that are running, at times, VERY slowly. The machine will run really poorly then boom, back up to full speed. There isn't usually enough time to check Task Manager real quickly to see what is running, not to mention the majority of the time there are people using the computer that don't know what the Task Manager is. ;) It would be really nice to take a look at some logs and see if, maybe, the anti virus is randomly taking alot of CPU for stretches of time. Or another application. Thanks! EDIT: This is for Windows XP. Sorry for the oversight. :)

  • Recommended: IntelliCommand for Visual Studio 2010/2012

    - by WeigeltRo
    The Morning Brew is a great news source for developers for many years now. In its most recent post it mentioned an extension for Visual Studio 2010 and 2012 called IntelliCommand that implements something that I had wanted for quite some time: Some kind of dynamic help for hotkeys. IntelliCommand shows a popup when you press and hold Ctrl, Shift or Alt (or combinations thereof) for a configurable amount of time, or after you press the first key combination of a chord shortcut key (e.g. Ctrl-E) and wait for an (independently configurable) amount of time. In the following screenshot I pressed and released Ctrl-E, and after a short delay the popup appeared: The extension is available in the Visual Studio Gallery, so finding, downloading and installing it via the Extension Manager is extremely simple: The default delays (2000 / 1600 milliseconds) are a bit long for my liking, but this can be changed in Tools – Options: So far things are working great on my machine. Some known issues do seem to exist, though (e.g. that the extension doesn’t work on non-EN versions of Visual Studio). See the author’s comments in the announcement blog post and in the Visual Studio Gallery for more information.

  • Outlook attachment save prompt behavior

    - by kara-marfia
    It seems they've put some Clippy-like behavior into Outlook 07. Assume you open an email message and open its attachment, given that you make no changes to the message or the attachment. If you close the attachment, then close the email - works as expected Close email - prompted to save changes to attachment I have some clerical users, and they tend to believe what the computer tells them. In this case, I'm having a hard time determining the reason someone determined that Outlook should lie in this case, and prompt someone to save a file that hasn't changed. Regardless, I've only been able to find examples of people failing to find a fix for this. Anyone have ideas? edit: I should have clarified, I suppose I'm looking for a workarounnd, as it's consistently reproduceable for any machine, and I suspect is therefore "working as intended"

  • OpenVPN - Ubunut 10.04 - Client Can't Connect to Server - Linux Route Add Command Failed

    - by nicorellius
    I suppose this could be asked on Server Fault as well, but it is specific to the client so I thought I'd start here. I have keys for a OpenVPN server already in place. I have used these keys to connect already, but using a Windows XP machine. I started by building the client.conf file so that I could run: sudo openvpn --config client.conf And it seems correct but I still can't connect and get these errors and lines of output: Mon May 31 14:34:57 2010 ERROR: Linux route add command failed: external program exited with error status: 7 Mon May 31 14:34:57 2010 /sbin/route add -net 10.8.0.1 netmask 255.255.255.255 gw 10.8.0.17 SIOCADDRT: File exists Mon May 31 14:34:57 2010 ERROR: Linux route add command failed: external program exited with error status: 7 Mon May 31 14:34:57 2010 Initialization Sequence Completed I searched the net for forums and ideas and tried some file moving and renaming but still ended up in the same place.

  • How to install old versions of gcc on Fedora without a VM?

    - by mikeh
    Hi, I need gcc 4.3 running alongside the shipped 4.4 on an FC13 machine. I can't do the VM solution discussed at http://serverfault.com/questions/88445/how-to-install-old-versions-of-gcc-on-fedora-12 since I need hardware access (CUDA computations on the graphics card). There's no compat-gcc-43 package (only compat-gcc-34). So I've built gcc by hand and am now trying to decide how to "install" it. Could anyone confirm that this was my only option, and/or suggest a best practice for how to manage the side-by-side gcc versions?

  • Add a Real-Time Earth Wallpaper App to Ubuntu with xplanetFX

    - by Asian Angel
    Are you tired of the same old wallpaper on your Ubuntu desktop? Now you can go from blah to literally spacious, real-time styled views of Earth with the xplanetFX Wallpaper App for Linux. You can conveniently access the “file type” downloads, screenshots, and jump-to links all on the front page. For our example we downloaded the .deb setup file on our system. The setup file will need to download three additional files to complete the setup process. After those are downloaded all dependencies will have been met and you can complete the installation process. Once that is done you can find xplanetFX by going to the Accessories Section of your Ubuntu Menu. This is what the main control window looks like when you start xplanetFX for the first time. You should take a few moments to look through the various tabs and tweak the settings for items like location, screen resolution, timing, auto-start, etc. When you are done click on Execute and within a few moments your desktop will have a fresh new look! Note: It took ~30 seconds for the display to activate on our system. Have fun with xplanetFX! xplanetFX Homepage [via OMG!

  • How to ...set up new Java environment - largely interfaces...

    - by Chris Kimpton
    Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

  • Changing Win 8.1 Pro Store App Installation Folder

    - by ChiliYago
    I have a Dell Venue 8 Pro tablet with Windows 8.1. The c:\ is very limited capacity at only 24GB. With the OS only on the c:\ I just have 8.6GB of free space. So I have added a 64gb SSD to the machine and want to install all my apps on it and not the C Drive. I know the apps get installed in c:\Program Files\WindowsApps folder so I have ROBOCOPY'd all the files to d:\Program Files\WindowsApps and created a symbolic link using mklink. It seems that new apps are install correctly now on d:\ however the existing apps fail to open. What is the Microsoft's solution to making this happen seamlessly?

  • Switch computer off automatically when the internet is disconnected

    - by Vin
    Is there any free software that will detect the status of internet and shutdown the system when the internet disconnects? Or (more generally) can something run a task when the internet disconnects, and I can route it to shutdown the machine? I am downloading things overnight. But my problem is that sometimes the internet connection will be disconnected in the middle of the night, so there is no point in keeping the system running the rest of the night. So I need to avoid this problem by detecting the net connectivity.

  • Options for installing software on Amazon EC2 Windows instances

    - by gareth_bowles
    I've been running Linux servers on Amazon EC2 for a while now; the experience has been great. I've recently needed to bring up a Windows server to run some Windows-only software that our product needs to use, and am running into a problem figuring out how to install the software, which is only available on DVD. With Linux I can just install packages from a Web-based repository and take advantage of EC2's fast network throughput, but so far on the Windows instance I've had to upload my ISO images to EC2 and mount them from the Windows EC2 instance. For some reason I'm getting really slow upload speeds to EC2, even though the regular upload speed from our office is pretty good (around 7Mbps). I've also tried mounting the DVD drive on my machine as a local drive on the EC2 instance via Remote Desktop, and then running the software install from the local drive, but I run into the same slow upload speed issue. Does anyone have a better way to install software from physical media onto an EC2 instance ?

  • How to backup/restore OSX Parental Controls before/after complete reimage?

    - by Jim Anderson
    We typically "nuke and pave" users Mac OSX laptops if they have software issue. Prior to doing so, we backup the primary (non-admin) user's home folder. Our standard image has four accounts: Admin (uber admin user); Parent (admin account for the parents of students); Loaner (so our standard image will also work for our loaner laptop pool); Student (this is the primary, non-admin user of the laptop) Our standard image has only minimal Parental controls on the Loaner and Student accounts. Some parents choose to tighten the parental controls. We never know when parents have made changes to parental controls, or what those changes are. Once we have reimaged the machine with our standard image (minimal parental controls) we would like to be able to restore any custom parental controls parents may have placed on their student's account. Any help in this would be appreciated. Thanks.

  • Files listed by bash but unaccessible

    - by Cerin
    What would cause the following behavior on an Ubuntu 12.04 system? I've SSHed into a machine as the "ubuntu" user. Running ls -lah /data/* shows dozens of non-empty files (e.g. file1.txt, file2.txt, etc), all owned by the "ubuntu" user/group, and with full read/write access. If I try to cat /data/file1.txt, bash gives me the error "cat: /data/file1.txt: No such file or directory" In short, ls is listing files, but in every other way, the files essentially don't exist. I can't cat them or read them in any way. Even giving all the files 777 permission doesn't change anything. This is really bizarre. What's going on here?
