  • USB3 does not work in fresh Ubuntu install

    - by Adéline
    I have a new computer with an Asus P8Z68-V LE + Intel i2500 + 8GB of RAM. I installed Ubuntu without any issue, but the USB3 (from the motherboard - on the back of the computer) doesn't work. I plug a USB stick -- nothing, I plug my USB3 external drive -- nothing, when I plug them into the USB2 and everything works perfectly. Also, I ran all updates and everything is up to date. What am I missing?

  • Windows 8 install fails

    - by HackToHell
    I have the windows 8 release preview 32 bit iso and it fails to install when booted out of a flash drive, it copies the files and the boot loader installs but the install hangs when I boot into Windows 8 the first time, it simply keeps on spinning forever. I did a vhd install of Windows 8 developer preview and it installed fine. Looking at the partition from Windows 7, I can see that the files are present.

  • Best tool to backup your firefox shortcuts

    - by vaccano
    I have lost my shortcuts a few times (from hard drive crashes). Is there a good tool to back them up easily. (I would prefer to not have to remember to do it.) Backing them up to the internet would be a nice bonus, but it is not required for my needs.

  • Is it possible to use Linux as a Fibre Channel Raid Disk Box?

    - by SvenW
    You probably all know the relatively simple RAID boxes exporting a bunch of SATA disks as one big drive via FC, SAS or iSCSI, like the HP StorageWorks MSA2000, Infortrends EonStore series or many different other models from different manufacturers. Is it possible to create such a device with Linux, a few disks and an FC controller, using the controller in the reverse direction than usual? This would come handy to test some ideas and concepts in an emerging SAN environment.

  • Easy way to deploy the recovery parition in Windows 7?

    - by Jesse K
    We're using ImageX to deploy Windows 7 Professional. We've gotten the Windows partition to work, but the recovery partition (100-200MB at the front of the drive in a standard install) isn't as simple. Here's a Technet guide I found: http://technet.microsoft.com/en-us/library/dd744280%28WS.10%29.aspx That looks like it could work, but would take alot of time if we need to do that for every single machine we deploy. Is there a faster/automated way?

  • Recommended USB 3.0 PCI/PCIX adapter for older Dell

    - by user32996
    Can anyone recommend a USB 3.0 adapter for my older Dell server? It does not have PCI express (PCIe) so I was looking for PCI or PCIX. I have been burned in the past installing "desktop" class drives on servers (i.e. blue screens under heavy load) so I would rather pay more to get something reliable. We are hoping to get better speed on our backups to an external drive, even 10% improvement would be worth it.

  • I need to configure Thunderbird to read from my local hmail server.

    - by user2565738
    I'm using hmailserver and am attempting to connect to it through thunderbird. I can see how to setup from a external server, but not internal. I can't seem to find the settings to set this up and am not even sure if they exist. I have connected hmailserver to an account already so it has downloaded the emails to my local hard drive, but I need to put them in some readable format. That's what I was hoping I could do with Thunderbird.

  • Wondering about the Windows 7 serial number my laptop has, and its uses.

    - by overmann
    So that's the serial number of my pre-installed windows copy, I take it. But am I allowed to use it again when, say, I don't know, my system gets crippled by a sneaky virus? If I format my computer and install windows starter again from a USB drive (speculating. I've never format before, I suppose is completely possible) Is that serial number still valid? I'm talking about the number printed on the back of my laptop.

  • How to reliably map vSphere disks <-> Linux devices

    - by brianmcgee
    Task at hand After a virtual disk has been added to a Linux VM on vSphere 5, we need to identify the disks in order to automate the LVM storage provision. The virtual disks may reside on different datastores (e.g. sas or flash) and although they may be of the same size, their speed may vary. So I need a method to map the vSphere disks to Linux devices. Ideas Through the vSphere API, I am able to get the device info: Data Object Type: VirtualDiskFlatVer2BackingInfo Parent Managed Object ID: vm-230 Property Path: config.hardware.device[2000].backing Properties Name Type Value ChangeId string Unset contentId string "d58ec8c12486ea55c6f6d913642e1801" datastore ManagedObjectReference:Datastore datastore-216 (W5-CFAS012-Hybrid-CL20-004) deltaDiskFormat string "redoLogFormat" deltaGrainSize int Unset digestEnabled boolean false diskMode string "persistent" dynamicProperty DynamicProperty[] Unset dynamicType string Unset eagerlyScrub boolean Unset fileName string "[W5-CFAS012-Hybrid-CL20-004] l****9-000001.vmdk" parent VirtualDiskFlatVer2BackingInfo parent split boolean false thinProvisioned boolean false uuid string "6000C295-ab45-704e-9497-b25d2ba8dc00" writeThrough boolean false And on Linux I may read the uuid strings: [root@lx***** ~]# lsscsi -t [1:0:0:0] cd/dvd ata: /dev/sr0 [2:0:0:0] disk sas:0x5000c295ab45704e /dev/sda [3:0:0:0] disk sas:0x5000c2932dfa693f /dev/sdb [3:0:1:0] disk sas:0x5000c29dcd64314a /dev/sdc As you can see, the uuid string of disk /dev/sda looks somehow familiar to the string that is visible in the VMware API. Only the first hex digit is different (5 vs. 6) and it is only present to the third hyphen. So this looks promising... Alternative idea Select disks by controller. But is it reliable that the ascending SCSI Id also matches the next vSphere virtual disk? What happens if I add another DVD-ROM drive / USB Thumb drive? This will probably introduce new SCSI devices in between. Thats the cause why I think I will discard this idea. Questions Does someone know an easier method to map vSphere disks and Linux devices? Can someone explain the differences in the uuid strings? (I think this has something to do with SAS adressing initiator and target... WWN like...) May I reliably map devices by using those uuid strings? How about SCSI virtual disks? There is no uuid visible then... This task seems to be so obvious. Why doesn't Vmware think about this and simply add a way to query the disk mapping via Vmware Tools?

  • Can't install .NET 4.0 on Windows XP virtual machine! (VMWare Player)

    - by Vercas
    So, every time I try to install .NET Framework 4.0 on my Windows XP Professional SP3 VMWare Player virtual machine, I get a fatal error. It doesn't work with either Windows Update, the Web Installer or the normal installer! I don't know if it matters (AND I HOPE IT DOES NOT), but the host OS's Operating System drive is encrypted, and the VM HDD file resides on that partition. I don't think it matters because other programs can be installed! And downloaded!

    - by user35934
    I've installed Windows 7 onto my Dell Inspiron 1420 (32-Bit). I don't have an internet connection at home, so I want to download drivers into my flash drive. I searched Dell website for drivers but didn't find anything exclusively for Windows 7. Can anyone direct me to the archive/repository where I could find drivers which suit my requirement.

  • Uuntu 9.10 will not boot

    - by Jim
    After an update yesterday my Dell X300 will only boot to a screen with an option to perform 2 memory tests. If I perform these tests, it will only go back to this same screen, offering a choice of memory test again, 86+ or 86+ serial console 115200. This screen is headed - GNU Grub version 1.97 beta 4. This is a full install on my hard drive. How can I get back to booting normally?

  • How to remove hiberfil.sys

    - by Chadworthington
    I have a small SSD and I want to reclain the space currently used by the hiberfil.sys (~4GB) by disabling hybernation or perhaps preferably, move it to an HDD. I see under "power Options" that "Sleep/Hibernate After" is set to "Never", yet I have this 4 GB hiberfil.sys file. I don't see any other options pertaining to Hybernation. how do I remove this file and keep it from coming back or relocate it to another drive, an HDD where I would not mind the frivelous writes to take place.

  • Architectural advice - web camera remote access

    - by Alan Hollis
    I'm looking for architectural advice. I have a client who I've built a website for which essentially allows users to view their web cameras remotely. The current flow of data is as follows: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Ftp connection is enabled for the cameras ftp user. Web camera opens ftp connection to server. Web camera begins taking photos. Web camera sends photo to ftp server. On image url request: Server reads latest image on hard drive uploaded via ftp for camera. Server deleted any older images from the server. This is working okay at the moment for a small amount of users/cameras ( about 10 users and around the same amount of cameras), but we're starting to worrying about the scalability of this approach. My original plan was instead of having the files read from the server, the web server would open up an ftp connection to the web server and read the latest images directly from there meaning we should have been able to scale horizontally fairly easily. But ftp connection establishment times were too slow ( mainly due to the fact that PHP out of the ox is unable to persist ftp connections ) and so we abandoned this approach and went straight for reading from the hard drive. The firmware provider for the cameras state they're able to build a http client which instead of using ftp to upload the image could post the image to a web server. This seems plausible enough to me, but I'm looking for some architectural advice. My current thought is a simple Nginx/PHP/Redis stack. Web camera issues post requests of latest image to Nginx/PHP and the latest image for that camera is stored in Redis. The clients can then pull the latest image from Redis which should be extremely quick as the images will always be stored in memory. The data flow would then become: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Camera is sent an http request to start posting images to a provided url Web camera begins taking photos. Web camera sends post requests to server as fast as it can On image url request: Server reads latest image from redis Server tells redis to delete later image My questions are: Are there any greater overheads of transferring images via HTTP instead of FTP? Is there a simple way to calculate how many potential cameras we could have streaming at once? Is there any way to prevent potentially DOS'ing our own servers due to web camera requests? Is Redis a good solution to this problem? Should I abandon PHP/Ngix combination and go for something else? Is this proposed solution actually any good? Will adding HTTPs to the mix cause posting the image to become too slow? Thanks in advance Alan
