• Broken pipe on nginx

  - by schneck

  Hi there, I set up php/fastcgi with nginx and now I want to upload very large files via a java-applet. After about 30 seconds, the applet reports a "Broken pipe". In the server logs, i find nothing. I changed any setting in the php.ini (max_execution_time, max_input_time, memory_limit, post_max_size) to very high values, but nothing helps. Any idea?

• Best way to reformat/recover in Windows when your CD key is no longer valid?

  - by CSarnia

  I have a copy of Windows 7 Professional that I have downloaded from the MSDN e-academy (thanks to my school). Now, the problem is that these license keys are one-use only. If I need to reformat or do a factory reset, what is the best way for me to do so, without invalidating my license and screwing me out of an operating system? Edit: I would also like to know some information on the "restore to factory settings" option in Windows 7 recovery center. Does it do exactly as the name implies and starts you off as if you had just done a fresh install? If I had some kind of nasty trojan or virus, would it be able to survive through the factory reset? The recovery center also has an option for reformatting, though I don't think that it's an actual format - it just backs up your stuff into a Windows.old folder or something like that. Does that require a valid license key?

• When running Adobe Acrobat's OCR on a PDF document, which downsampling produces a higher quality: 600 dpi or 72 dpi?

  - by Ricardo Altamirano

  I have a large PDF document that consists of scanned pages of a textbook. I want to run Adobe Acrobat 9's text recognition function on it, but I'm presented with this menu when I do. I'm confused by the options in the highlighted menu. What option will produce the highest quality/most readable text? I thought 600 dpi implies a higher quality image than 72 dpi, so I'm confused by "High (72 dpi)" and "Lowest (600 dpi)."

• Prevent auto forwarding NDR loops

  - by DemonWareXT

  a week ago we experienced a really sweet problem at a client of ours. They are a school with around 1200 users, and everyone of them has auto forwarding for all mail activated. We use Exchange 2010 Now a few of the users where able to make NDR loops by adding 2 different, wrong, destinations. We had around 80k mails sent within a few hours. Not very practical. My question is, does anyone know a good way to prevent something like this. I have found 2 ways, which both fail for their own reasons We could manage the auto forwarding on the exchange host itself, which should prevent this looping problem someone said. But 1200 Users, not on my watch. There is a Powershell script out in the wild which should work against that, but my employers want something more "professional" Thank you very much for your support Linus

  Have seen some highly compressed files around.(for eg: i have seen 700mb of data compressed to around 30-50mb) But how do you get such compressed files, I have tried using softwares like Winrar and 7Zip but have never achieved such high compression. What are the techniques/software that allow you to compress files so well? (P.S. I'm using Windows Xp)

• Multithreaded TIFF to PNG conversion

  - by mtone

  I'm working with images of scanned books, so hundreds of high resolution pictures. I'm doing conversion work with Photoshop Elements - I can quickly save them to uncompressed TIFF, but converting to compressed PNG using a single thread takes ages. Do you know a software, ideally simple and free, that would batch convert those TIFFs to PNG in a multi-threaded manner (4 to 8 simultaneous files) to take advantage of those cores and cut converting times? I'm not too worried in slight variations in final size.

• PC cannot see Clonezilla server when using PXE Boot

  - by r2b2

  Hi I have about 15 workstations, all have the same hardware specs so I figured clonezilla is perfect for cloning them. So I followed everything this guide says :cloning groups of school computers That guide above makes it all look easy but when I tried setting up Clonezilla Server Edition on my laptop (Kubuntu 10.10) and configured the master computer for PXE boot, the master computer could not see the Clonezilla server. It just shows 'DHCP...' which seems it trying to grab an IP address but to no avail. Please help. Thanks!

• Trackpad and USB mouse - different settings

  - by soupagain

  On my laptop I use both the trackpad and an external USB mouse. I'd like different settings for each device. e.g. the mouse is high resolution so I prefer to use a slow mouse settings, and for the trackpad I prefer to use the "Enhance pointer precision" option. But I can only seem to set these option for both devices, not individually. Can this be done? [Windows 7]

• Data Center Design and Preferences

  - by Warner

  When either selecting a data center as a co-location facility or designing a new one from scratch, what would your ideal specification be? Fundamentally, diversified power sources, multiple ISPs, redundant generators, UPS, cooling, and physical security are all desireable. What are the additional key requirements that someone might not consider on the first pass? What are the functional details someone might not consider during the initial high level design?

• How to remove RAID flag on unstriped drive without losing data?

  - by Alex Folland

  I have a Gigabyte Z68X-UD4-B3 motherboard. It advertises this new thing called "XHD", which is like RAID but makes a SSD and traditional-style drive work together to enable high speed with high capacity. I don't want to use this feature, and I already have Windows 7 64 installed without using this feature. When I first installed my 2 hard drives (1 SSD and 1 traditional-style drive) in my machine and booted it up for the first time, it ran a program from the mobo that asked me if I wanted to set up XHD. Thinking it would go to some config screen, I said yes. It immediately started doing something with my drives and finished. I considered that strange, but figured it wouldn't matter when I simply install Windows onto my SSD only. I now have my BIOS and Windows running in AHCI mode with no RAID arrays and separate drives. My SSD is one of those new Corsair Force GT drives which loses power every so often, causing Windows to BSOD. I've figured everything out about this problem, including installing the latest firmware from Corsair, and the only way to fix it at this point is by installing Intel Rapid Storage Technology to control AHCI instead of Windows, since the Windows AHCI driver disables the drive's power every once in a while and can't be configured not to do so. I've tried installing Intel Rapid Storage Technology. When I reboot my machine after doing so, it BSODs just after the Windows logo. I've figured out this is because my SSD and my traditional drive are flagged as RAID, as seen in the "Intel Matrix Storage Manager" program found by switching the BIOS hard drive handling to "RAID" mode. This is due to the XHD auto-config program I mentioned earlier. Normally, the BIOS is set to AHCI, and when the drives boot in AHCI mode, they work perfectly. So, I've concluded the data is stored in AHCI mode but the drives' flags are set to RAID. I've figured out that I can accomplish my objective by using the "Intel Matrix Storage Manager" program on the mobo (with "Reset disks to non-RAID"), but doing so would cause it to completely wipe the drives I select. I want to simply toggle these flags from RAID to AHCI so Intel Rapid Storage Technology doesn't fail and cause a BSOD upon booting, but without wiping the drives.

• Exchange 2003 mailbox migrated to 2010 not showing up in Address book

  - by TJ

  I have migrated about 45 mailboxes at this point from our single instance of Exchange 2003 to a High Availability Exchange 2010 environment successfully. However one mailbox moved successfully and the user is able to send and receive e-mail internally and externally with no problems but they do not show up in the Global Address List. The OAB is owned by an Exchange 2010 mailbox server. What am I missing?

• What OpenSource iSCSI appliances/apps support windows clusters?

  - by Jimsmithkka

  I have been wanting to experiment with Windows clustering systems in my spare time, so I need a free, preferably open source, iSCSI Target that can support 2k3 and 2k8 fail-over and possibly High availability clustering. I have tried the ubuntu iscsi target package in a vmware environment, but it fails at the 2k8 tests. In simple terms I want to build a "Poor man's San" for windows and have it be able to do more than just be drives.

• Sharing accounts between multiple computers running Ubuntu Linux

  - by john

  My school has a computer lab full of machines running Red Hat Linux. They have it set up so that you can log into any computer in the lab, and it automatically loads your desktop, home directory, etc, which makes it so all computers in the lab look the same to you, regardless or which one you're using. I have two computer at home running Ubuntu Linux. Could I do this same thing with my computers at home? What's it called, and how do I find documentation on how to set it up? Thanks!

• Windows 7 changes desktop icon location when switching from External Monitor to Internal Monitor (laptop)

  - by Gareth Jones

  I have a Windows 7 Laptop, and lately its been acting really weird with my 1080p Monitor. When I get home from school, Ill plug my screen in, and close my laptop lid (which makes the laptop treat the Monitor as the primary and only screen). However it will move my desktop icons! This also happens when I remove / unplug the screen, as shown in the pictures. I hate this, as Im the kinda person who's use to every icon being in a set spot, and so am use to their location. Its a massive hassle to try and move the icons back to their original spot. Anyone have any ideas on how to fix this? Thanks P.S it could be due to the resolution of the screen's being different, but this never happened before in the past Icons on External Moniter (after having moved them manually back into place): Icons after unplugging external monitor (and so using Laptop screen):

• process running on login: can't find in AD or login batch scripts

  - by tombull89

  Hallo, I'm trying to deploy some classroom control software (NetSupport School) to some of the machines on our network but for some reason when you log off and restart the computer any user who logs on ends up re-installing the software while logging on. I spent two hours on the phone to the complanys support and we eventually nailed it down to most likely a setting in Active Directory or in the login.bat (drive mapping and settings) but we can't find anything in those that would say "run this installer at logon". Is there anywhere else on the system that would set something like this? Server 2003/XP. Ta!

• Dediced server for all network functions?

  - by Alan

  I want to set up a fictional network configuration for a school in my neighborhood. They have about 50 computers altogether, 2X20 in computer rooms for students and another 10 scattered around for various professors. They should all access the internet through a dedicated Linux router machine. What they would like is to have domain names for those three computer groups. Lab1, Lab2 and Professors. The computers in Lab2 and Lab1 should have static ip and should all be named by numbers. So there should be 1@Lab1, 2@Lab1.... etc. And the Professors network should have a DHCP, with authentication. Is it an ok solution to have all these functions on a single server? (The one which will be used as a router) Do I have to set a local DNS for domain naming? Do the host names for Lab computers have to be set on the clients, or can they be automatically assigned?

• How to make Windows display application crashes in the console?

  - by Name is carl

  I'm developping a C application on Windows 7 64 bits, and each time it crashes I get the following dialog: I would prefer something more "old school" with the complete error dumped in the console.

• How to track my kid's Multi-Browser website history

  - by Rachel

  My kid is 14, homeschooled and capable computer user. All of her school work is done online; the computer literacy course even uses 3 different browsers, Chrome, IE, and Firefox. I have 2 laptops, running Win7 (one is Pro, the other Home). Is there a way to get all of her browser history in one place? I have to account for 60 minutes of class time per subject per day, but trying to do this across all 3 is getting too complicated. Thanks! PS. My kid and I talk about internet safety and usage regularly and she knows that I monitor where she goes and how long she is there. Secrecy is not an issue.

• Is it possible to get a list of running processes with a Cloudwatch Alarm?

  - by jtalarico

  We have an EC2 instance (Ubuntu) that has a few java-based applications and lately we're getting hit with high CPU utilization spikes that trigger one of our Cloudwatch alarms. By the time we get into the server to look at the cpu utilization, things have calmed down. What we'd love to see in one of the alarm emails is a list of running processes and their cpu utilization(%) at the time of the alarm. Is this even possible?
