• fdisk (linux) partitioning raid0

  - by silverrocker

  'm trying to create partitions for a slackware instalation on my computer (beside Windows 7) just to have a nice distro running mostly for school but when I run fdisk and print the partitiontable I get the following message: Partition x does not end on cylinder boundary. (in my case x = 1, just using x to help googlers). I must say I'm using a raid card (AMCC 3ware 9500S SATA RAID Controller). Maybe this is the problem. How can I fix this without loosing any data? (I've posted this qeustion on stack overflow aswell but then people sugjested it should be moved to here, but I don't know how to move my question so I just posted it here manually (I hope that's ok))

• How can I access an Apple Xserve with no I/O ports

  - by DigitalJedi805

  I have an Apple Xserve at my place of employment, that I stumbled across one day going through some old equipment. The Xserve has one card installed on it, being the NIC, and is labelled with the static IP adresses that it has assigned, but other than that it is totally 'headless'. I would like to put it to use ( by either rolling it over to a Linux, or Windows Server 08 environment... 0_o ) but have yet to figure out how to get into the system to manage it. I'm a frequent at StackOverflow, but this is my first SuperUser post, so please let me know if this should be on one of the affiliate sites.

• How to assign fine grained permission on shared mailboxes?

  - by sudhirc

  Typically you can assign either Full and Sendas permissions to mailboxes using Powershell. In our organization we have a need to assign other fine grained permissions like editor, reader , author to the shared mailboxes. We are using a third party tool to achieve this. I am pretty happy with the tool except for that fact that it is a GUI only tool. I am trying to automate the entire process of shared mailbox creation by using a combination of embedded powershell in C# program. All other steps are easy to automate but because this tool is GUI only, I am really struck. Is there an API method available to to achieve this? I guess EWS API can provide some answer but I really do not know where to start.

• getting a 404/403 error for payment gateway

  - by Obay Ouano

  We are setting up an online payment facility using a payment gateway. After the payment gateway finishes processing the credit card details for a payment, the user is redirected to a "403 Forbidden" page. The logs show: [MY_IP_ADDRESS_HERE] - - [SOME_DATE_HERE] "GET /POSTBACK_URL.php?txnid=1338434567&result=failure&reason=The+remote+server+returned+an+error%3a+(404)+Not+Found.&digest=7a115270c56df5945c43ad86e56b2e930a3cfd50 HTTP/1.1" 404 - "PAYMENT_GATEWAY_URL_HERE" "BROWSER_DETAILS_HERE" It means that when the PAYMENT_GATEWAY_URL attempts to open our POSTBACK_URL, it gets a 404 error, is that correct? But why does the page say "403 Forbidden"? Anyway, we tried to copy-paste that same URL into the browser window, and the page is opened successfully, with our programmed error notification message. So, why couldn't it be opened when the payment gateway tried to redirect to it, but we could? Is this some sort of permissions issue? If so, the postback URL's file permissions are already 755. What am I missing?

• Dell Latitude E6400 power button and wireless not working or only working intermittently

  - by Droid

  The power button on the laptop stopped working randomly as of a day or two ago. I can only power the laptop on if its attached to a docking station, on which I can use the power button to turn on/off the laptop. Today the wireless card stopped working (the wifi light does not turn on, even after I turn on the wireless switch). What is the problem and how can I fix it? The laptop is about 1 year old. I have not dropped it, but do carry it around a good amount, including docking it/undocking it frequently.

• Windows 7 Recurring Blue Screens: MEMORY_MANAGEMENT 0x1A

  - by Chris C.

  I have recurring BSODs that really have me scratching my head. Here's a look at the errors: MEMORY_MANAGEMENT 0x1A (ntoskrnl.exe) - I've seen this 9 times since April 2012 NTFS_FILE_SYSTEM 0x24 (Ntfs.sys) - this one's new, happend 4 days ago BAD_POOL_HEADER 0x19 (win32k.sys) - also new, happened 7 days ago My system specs: Intel Core i5 2500K @ 3.30GHz ASUS Sabertooth P67 Motherboard (Rev 2) * RMA'd my Rev 1 due to recall 16GB (4 x 4GB) Kingston HyperX 1600 MHz DDR3 RAM 2 x 640GB Western Digital Caviar Black 64MB SATA HDD EVGA NVIDIA GeForce GTS450 1GB PCI-E 2.0 Graphics Card I've got Windows 7 Home Premium and it's completely patched. I'm also running Microsoft Security Essentials, which is up-to-date and always present. I've run MemTest86+ from a USB drive for up to nine hours, giving my RAM a total of 6 passes, and it didn't detect a single error. I've used chkdsk in Windows 7 to scan the C:/ drive on boot (twice) and it found no problems. How can I find out what's causing all these blue screens?

• Cheapest way to go for somebody who wants to accept payments, but won't be accepting hundreds of ord

  - by blockhead

  I have a client who lectures, and wants to sell spots to his lecture online. I would preferably like to set him up with a solution that allows me to collect billing information on his site. My experience with e-commerce is in using solutions like Authorize.net, however this does not seem cost effective since I can't imagine he's making a huge profit off of this. I'm afraid he would lose money in the cost of using Authorize.net (or any payment gateway for the matter). I could use google checkout or paypal express, but this would require me to leave his site (although with google checkout, it looks like, from a glance, that I could just submit to their form from my server, and likely with paypal as well, but I don't know if this is against their TOS). What is the most cost-effective solution for accepting credit card payments in this situation?

• Volume randomly turning itself down on Windows 7 64-bit

  - by Arda Xi

  This is the weirdest issue I've ever encountered with my PC. Every so often, my sound will start playing back at a lower volume. This happens when watching video, listening to music, all independently. It usually lasts anywhere up to a minute, after which it will turn up again. The weird thing about it is that the volume control in Windows remains at 100%, even though the volume is audibly a lot lower. (No, I'm not going deaf, it's just my PC. I checked.) I just have no idea where to go to troubleshoot this, even. I'm using Windows 7 64-bit with an on-board Realtek sound-card. Oh, just in case someone finds this question on Google or whatever, making sure this is on Do Nothing may fix your problem. Unfortunately, it did not work for me. My settings all seem fine. This is my audio slider. (Took the screenshot while the issue showed.)

• Development environment for embedded system

  - by Howard Lee Harkness

  I need to develop software in C/C++ for an embedded system. I have Debian 6 running off of a USB hard drive. I would like to be able to generate a stripped-down kernel with modules, and install them either on a CF card or a USB 'thumb' drive. I succeeded in building a Linux 3.6 kernel and running it in Debian off of the USB hard drive, but I am having trouble figuring out how to install it on the thumb drive. I would like a build cycle that looks like this: 1) Build module or kernel with desired software 2) Install it on thumb drive 3) Boot and test I would like to use the same system for both development and testing, if that is feasible. I am looking for resources and tutorials that would help me understand how to do this.

• Using Windows 7 XP Mode for games

  - by Josefvz

  Hi all. I have Win 7 (x64) at home and I want to play some old games (specifically Lands of Lore 3, but also some others). This game does not work properly on Win 7, and there are no patches that I'm aware of to fix its issues. Can I use XP Mode to play this game (and other non Win 7 nice games), or is there a better way? I only have one PC and dual booting scares me... (so no to dual booting!) Another question: Will I have full hardware support (full use of my graphics card, etc) when I use DOSbox or a VM? I have decided to go with VirtualBox or vmware, I'll check which one gives the best performance, thanks for your input!

• Is it valid for RSS feeds to include images with relative paths?

  - by Brian Armstrong

  I have an app which reads lots of RSS feeds. Someone added a feed recently that includes images in the html portion with relative URLS (i.e. it didn't include the http://www.domain.com/ part in front). Is this valid html for an RSS feed? I thought not, but I tried adding the feed to my Google reader and it picked up the images correctly, so they must be doing something smart where they guess the domain based on the feed's url parameter or something. Even if it's not valid, how common is it to see feeds like this in the wild? To display it correctly would require you to parse the html in the feed and find/replace parts of it to insert full URL's, so this seems wrong. But wanted to double check.

• Windows 7 Line In Delay Issue

  - by CheeseConQueso

  Not sure if this question should be posted on a different stack exchange site, so if you find that it should not be posted here, please move it. Either way, if you know the solution, please advise. I'm running Windows 7 Pro 32-bit on my Dell Latitude 2100 netbook and I'm having an issue with the line in device/driver/functionality. The device & driver are stock: Driver Date: 7/13/2009 Driver Version: 6.1.7600.16385 I'm almost sure that the manufacturer of the sound card is RealTek. The problem is that there is a delay (when monitoring input) between the source and the speakers. My setup is bass guitar running through a 12' long instrument cable (1/4") with a 1/4" female to 1/8" male adapter into the line in port on the computer. Then the 15' long headphones/line out cable goes into a standard set of powered speakers. How do I get rid of this delay? Thanks for any help.

• Screen is black at login screen if display driver is enabled

  - by Amir Rachum

  I have a Lenovo x200 and recently its screen didn't work, so I took it to a repair lab. The guy told me they replaced the screen inverter. I powered up the laptop and the ThinkPad logo was shown, so I was happy. When I got home the computer would boot up, then instead of the logon screen, I got a black screen. Went to safe mode, disabled the display adapters, reset the computer, and I got a clean boot. Then I tried to reinstall the drivers, and it just led to the same condition. My video card is (from device manager): Mobile Intel(R) 4 Series Express Chipset Family. Now my laptop works as I'm working with display drivers disabled, but without display drivers I can't watch movies, etc. Any solution to this problem? Edit: I plugged in an external monitor and it works on it with display drivers enabled. However, it does not find the laptop monitor.

• does the *physical* order/location of drives in a mdadm-managed RAID-10 array matter?

  - by locuse

  i've setup a 4-drive RAID-10 array using mdadm-managed, software-raid on an x86_64 box. it'd up & running and works as expected, cat /proc/mdstat md127 : active raid10 sdc2[2] sdd2[3] sda2[0] sdb2[1] 1951397888 blocks super 1.2 512K chunks 2 far-copies [4/4] [UUUU] bitmap: 9/466 pages [36KB], 2048KB chunk atm the four SATA drives are physically plugged into the motherboard's 1st four SATA ports. i'd like to gather the necessary/complete info for catastrophic recovery. reading starting here, http://neil.brown.name/blog, and the mailing list, i'm not yet completely confident i have it right. i understand 'drive order matters'. is that logical, &/or physical order that matters? if i unplugged the four drives in this array, and plugged them each back into different ports on the motherboard or a pci card, as long as i've changed nothing in software config, will the array correctly auto-re-assemble?

• Enable multiple audio output on Windows 7

  - by patrick

  For Windows 7, 64 bit: I have a digital SPDIF output to my stereo, which controls speakers in other rooms. I also have a set of speakers connected to the regular audio jack at the computer. This allows me to send music to the kitchen while my child plays games on the computer. Works great. Except when I'm playing games and still want to listen to music. ;-D I know I can manually switch WMP to play through the speakers instead of SPDIF, but I was wondering if there's any way to enable simultaneous audio out in Windows 7? Virtual Audio Card is a non-starter because I'm running 64 bits and the VAC driver isn't signed.

• Colored blocks on boot

  - by stackzerad

  When my laptop tries to boot right after POST I see colored blocks with flashing symbols in them. I am able to boot from windows PE cd. Tried fixboot and fixmbr with no success. I have also tried replacing boot files (ntldr, io.sys etc..) and removing video card drivers from windows\system32\drivers. The drive is seagate 2.5 ATA 160GB and has one NTFS partition on it. I have already fixed this issue by reformating the drive and reinstalling everything but after couple of weeks I get the same issue again. The diagnostics software shows no bad sectors on it and virus scan didn't find anything. Does anybody have an idea what this might be? UPDATE: tried defragmenting the hard drive just in case, but still no luck

• Sharing VPN from XP to Linux virtual

  - by user55513

  Hi I will keep the question simple with few details, if more is needed tell me. Thanks. I am playing around with networking and virtualbox. So I have 2 virtual machines. One is windows xp and another has linux in it. Windows XP has 2 network cards. One for the internet and the other to connect to the linux computer. Linux has one 1 card and it can only access the internet passing through Windows XP. Internet works fine until I activate OpenVPN on Windows. When I turn on VPN, Linux has no access to it. How can I make linux use VPN too? I believe it has something to do with using the "route" command on XP to send VPN traffic to Linux but I was not able to figure it out how yet.
