• Using LDAP/Active Directory with PIN based authentication

  - by nishantjr

  We'd like to integrate our service with LDAP, but because of hardware constraints, we're only allow 4 digit user ids and passwords. What would be the best practice for performing such an authetication? We've considered adding User ID and PIN attributes to the LDAP user schema, but we're not sure how happy people would be with modifying their schema to interact with our service. The PIN attribute would have to have the same support that native user passwords have. (hashing and salting etc.) UPDATE Another consideration is how ldap_bind works with this scenario. How do we get it to use an alternate authentication method? Can this even be done without affecting other services that use the same LDAP server?

• Turning a running Linux system into a KVM instance on another machine

  - by Charles

  I have two physical machines that I wish to virtualize. I can not (physically) plug the hard drives from either machine into the new machine that will act as their VM host, so I think that copying the entire structure of the system over using dd is out of the question. How can I best go about migrating these machines from their hardware to the KVM environment? I've set up empty, unformatted LVM logical volumes to host their filesystems, with the understanding that giving the VMs a real partition to work with achieves higher performance than sticking an image on the filesystem. Would I be better off creating new OS installs and rsyncing the differences over? FWIW, the two machines to be VM'd are running CentOS 5, and the host machine is running Ubuntu Server 10.04 for no particularly important reason. I doubt this matters too much, as it's still going to be KVM and libvert that matter.

• Straight-forward to Virtualise with XEN or KVM on IBM Server System x3650 M4 791562G?

  - by ChrisZZ

  I want to built a virtualised Server Environment using XEN or KVM. The virtual machines should be purely debian systems - so XEN or KVM should be a sane choice. Now while buying servers, I am confronted with the fact, that the vendors obviously only support commercial solution. I think, on a good server, one should be able to install uncommercial software as well - but of course sometimes systems have hardware, that requires drivers, that are not found in the OS Community. So I am asked the question: Is it straight-forward to use Debian with IBM Server System x3650 M4 791562G with Debian - or even virtualising the IBM Server System x3650 M4 791562G using XEN or KVM. I am sure there will always be a way to achieve this goal - but this way might have a high milage - so I am not asking, whether this is theoretical possible, but whether this should be straight-forward and practically easy to do, no major headaches to be expected.

• ruby on rails server is intermittently slow

  - by Richard

  My rails installation was chugging along nicely. Last night we had to perform a hot-patch with was really a standard deploy of some exception code. Once capistrano finished the operation one of our admins discovered that there were two long running passenger processes. While we have deployed release over the past two weeks it would appear that these processes have been here and alive the whole time. Granted they could have been zombies or any other artifact and at this point we do not know what state they were in. Which leads me to the question: There are so many moving parts between the rails application and the OS/hardware that being a SME is probably no longer possible. So; how does a sysadmin perform root-cause analysis with any certainty? And: When do I just start rebooting servers?

• Hosting solution for sensitive client data

  - by Mark

  Hello, We are developing a web application that will deal with highly sensitive (financial) data of clients (audience is medium to large sized businesses). Clients will be under scrutiny from regulators & auditors and, as such, we will be too. More importantly to give clients a level of comfort our application and related hosting arrangement should instill a lot of confidence with them. We are looking into using a cloud based service like Linode, Amazon EC2, etc. To allow for maximum flexibility We are keen on putting everything on virtual servers and avoiding having to buy our own hardware. Does a cloud based service make sense for our particular scenario? If not what type of hosting should we consider? If so what should we look out for? Thanks!

• Does RAID negatively affect non-RAID devices?

  - by Django Reinhardt

  I am running Windows 8 on an SSD, and it's all running swimmingly, but I want to store documents on two HHDs (not SDDs) running under RAID 1. My motherboard has two SATA controllers, both set to AHCI. On the 3GB/s controller, all four ports are used (1 Bluray Optical Drive, 1 Spare HD, and the 2 I wish to turn into a RAID 1 drive). Windows is on the 6GB/s controller. Like so: So my question is: If I turn these four ports (on the 3GB/s controller) into a RAID controller, will that negatively affect the non-RAID hardware plugged into it? I.e. Will the HDD or Bluray drive be slower/incompatible with being plugged into a non-AHCI controller? Thanks.

• How can I create a bootable CD-ROM/USB Drive? (With NTFS + USB Drive support)

  - by RonK

  My motherboard got fried and I was forced to get a new hardware set (MB+CPU+RAM) so in most likelyhood I'll need to reinstall my Windows 7. I usually follow procedure and put the OS on the primary partition and my data on a logical partition - so I can format the primary without concern - but this time I made a mistakte and left some crucial items on the primary partition. I want to create a bootable CD-ROM/USB Drive which can read NTFS so I can access this data. If booting via a CD-ROM, I would prefer being able to connect a disk-on-key/My Passport to the computer and be able to access it to transfer the data to it. How can I do it? (free 3rd party applications are most welcome)

• How to convert WinXP + Apps on RAID0 to use just one of the two RAID disks?

  - by chris5gd

  I have two 150GB SATA drives in hardware RAID 0, on which I have my C: (Win XP) and D: (installed apps). I'm migrating to Windows 7, but I want to keep my XP system until I've got it all running smoothly. So I want to: break the RAID move C: and D: to one of the drives (there's enough room) use the other drive for Win 7 boot into one or the other Clearly I can't move C: and D: after breaking the RAID, so I'm assuming I need to image the two partitions first, then break the RAID and restore the images to one of the drives. So my questions are: Is this possible? If so, what would be a good (free) imaging/restore tool? How do I ensure that the drive will boot after restoring the images? What sort of gotchas should I look out for? If there's a better solution than this, I'd be grateful for suggestions. Thanks!

I want to install OS 7 but this makes it much more complicated. It's appearing as a hardware issue to me, however, what do I know. Any suggestions?

• Windows XP crashes by GT610 driver (nv4_disp)

  - by undone

  I have a PC which was working fine but one day screen went dark and nothing was shown. I thought the problem is graphic card, so I replaced it with new one. I bought a new graphic card (GeForce 610) and installed it on my system. I formatted my hard-drive and installed a fresh Windows XpSp3 and its drivers. Everything was fine but after installing graphic card's driver, I got an error saying windows got stuck in an infinite loop and it couldn't get out (in nv4_disp). I uninstalled it and downloaded its last version and installed it. Unfortunately, I got the same error and windows restated! Here's my system: Pascal Motherboard PT880PRO Intel CPU Windows XPSp3 I searched this issue on the internet and I found bunch of suggestions (from cleaning hardware to installing latest version of its driver) but nothing help! Any help would be appreciated! Thanks.

• How do you hit modifier keys when touch typing?

  - by Bob Ueland

  I am a programmer and I want to learn to touch type. As all programmers know, using modifier keys like Control, Command and Alt are essential. When programming I think that every second or third word I use involves a modifier key. But most touch typing learning software do not address these keys, it is as if they do not exist. Not only do they not let you practice them, they do not even tell you which fingers to use to hit them. Actually there is a touch typing game that I use called StarTyper (http://lidenanna.com) that lets you practice modifier keys and even make up your own custom words containing modifier keys. But not even this game tells you which fingers to use when hitting the modifier keys. Has anybody addressed this problem. Or are there just homespun methods that work for one person but not for the other?

• Linux (Ubuntu) USB Auth

  - by themicahmachine

  I want to be able to authenticate with PAM using a USB drive with a file on it. I've read about how to do this with a PAM module that reads the specific USB hardware ID of a device, but if the device malfunctions or is lost, there would be no way to authenticate. I would prefer to use the method BitLocker uses, requiring a particular file to be found on the drive in order to authenticate. That way I can keep another drive in a secure location as a backup. Any other suggestions are welcome. I just want to require a higher level of security that just a password.

• HP Presario CQ 61-322ER (VV884EA) Wi-Fi hang up!

  - by qgrabber

  I have my new laptop and don't have Windows XP drivers for it. I found that it contains the Broadcom BCM4310 chip, but when I install any Broadcom driver my laptop hangup on installing bcm5*.sys driver. Only power-off button make any effect. After reboot the device list (Device Manager) contains Broadcom WLAN adapter, but it is marked as disabled, for some hardware errror! Also if I disable device before, and install driver - then - all is OK! But when I try to enable it, Windows hang up anyway (no speaker beep, no mouse input, no keyboard input - nothing) What is the solution?

• Black Screen on Startup even after running chkdsk

  - by phwd

  I started an old (Dell Inspiron 2200) the startup goes all the way to Microsoft Windows XP Logo then I get a black screen. I am still able to move the cursor but that is about it. I tried running Recovery console (from CD) with chkdsk command. First time it said they were errors. I decided to do a fixboot and see if the errors went away. They did. Restarted and still no luck. If there are commands that I can call either from recovery console or elsewhere to further describe the problem please tell me and I will re-edit the question. srvtag:7XNSG81 Also what are my full range of options before wiping the hard-drive (if that is even the problem) I want to exhaust all options before replacing hardware.

• How can I access cpu temperature readings using c#?

  - by Paul

  For a programming project I would like to access the temperature readings from my CPU and GPUs. I will be using C#. From various forums I get the impression that there is specific information and developer resources you need in order to access that information for various boards. I have a MSI NF750-G55 board. MSI's website does not have any of the information I am looking for. I tried their tech support and the rep I spoke with stated they do not have any such information. There must be a way to obtain that info. Any thoughts?

• Can I reprogram a microphone input to be used as an audio output? (on XP)

  - by qftme

  I have a five year old Sony Vaio laptop (vgn-fw31m) that has had impact damage to the audio-output mini-jack for about the last year or so. In a recent discussion with my brother, we wondered whether it would be possible to write a program that would enable windows to use the microphone mini-jack input as the audio-output? As I currently use this laptop for work I am not keen to risk pulling it apart in order to replace the components comprising the audio-out. I therefore 'hope' that a programming solution exists. I would really appreciate any advice on this and eagerly await your response. Kind regards, qftme :)

• Error sysprepping Windows 8 Enterprise 90-day trial

  - by Philip

  I am using the Windows 8 Enterprise 90-day trial to evaluate the latest version of Windows for a private school. The way I work is that I use sysprep to prepare an generalized image, then I clone it to the school's computers. When I follow the instructions and try sysprep on my installation of Windows 8 in VirtualBox, sysprep thinks briefly and gives me an error message: Fatal error occurred while trying to sysprep the machine. Once I acknowledge it, sysprep closes. I checked the Windows Event Log, and there's nothing there that I could see. I also followed some instructions to cure this problem, but nothing changed. The error remains. My best guess is that the 90-day trial prohibits the use of sysprep, but I can't be sure. It might also be my use of VirtualBox, or who-knows-what. Has anyone had success with this, or encountered the same issue on real hardware?

• Ubuntu Wired network(ethernet does not work)

  - by user36777

  It was working just fine, until the other day I yanked it out. The wireless works just fine on the same router. If I login to a windows 7 instance on this dual boot laptop then the ehternet works just fine. So it's not a hardware, cable or router issue. The card even gets an ip, but I can't connect to the internet. Here are the details from route, iptables, ifconfig, ping etc. Any ideas? I have been struggling with this for day, none seems to have an answer. http://pastie.org/954816

• What OS for Eee PC ?

  - by crivateos

  Hello. I've just bought new Eee PC 1005 (with Atom N450, 250GB and 2GB memory) without any pre-installed system. Now I'd like to install windows and linux distribution on in. What should I choose ?

• Does the size of the monitor Matter?

  - by Arsheep

  I have a old computer, and I want to buy a big LCD. The best I've found so far is Viewsonic's 24" LCD TFT monitor. So will it run without any problems, or do I need to upgrade the video cards or something as well? The computer is not too old: it has P4 board and celeron processor, with 128 graphics memory. And in display properties, it says that the maxium that I can use is 1280 x 1024 resolution. I am noob hardware-wise, so need help on this stuff. Thanks

• Windows 7 startup problem

  - by elaine

  I purchased a computer a few weeks ago which runs on Windows 7. I was just watching a show on Hulu when it shut off. I don't know if I accidently pushed the power button with the keyboard or what. When I turned it back on my first screen says F5 key for HDD recovery. I pressed the F5 button and the screen goes to a Windows setup (EMS enabled) screen which then goes to my regular Starting Windows. After that one I get the box with x:/windows/system32/cmd.exe-startnent.cmd. If I don't press the F5 button I go to a screen which tells me Windows failed to start, a recent hardware or software change might be the cause. It gives me two options- Launch Setup REpair(recommended) or start Windows normally. I've pressed enter to choose the first choice but it does nothing but brings me to the same screen. Anyone have any ideas?

• Extract X11 configuration information from running instance.

  - by kasterma

  Since I had a hard disk die on me, I figured I could easily try some other OS (I usually run Ubuntu). Turns out that Ubuntu flawlessly recognizes my video card and monitor (X11 works right out of the box), and none of the other systems I tried gets anything working (I tried CentOS and FreeBSD). In my now working version of Ubuntu I cannot find a configuration file with information I could try to use with one of the other versions, which makes me guess that it just detects the hardware every time. Can I extract its choice for drivers and configuration options somehow (so I can try these same options in the other systems)?

• Monitoring/logging a malfunctioning internet connection

  - by Pekka

  I have a mysterious internet connection problem: Every 15-20 minutes, the connection will become very slow, and take 2-3 minutes for anything to load. I've had a technician from the ISP over here to test the hardware, and everything is in pristine condition. They have no other explanation than a configuration error on my machine, a possibility I can exclude 90% because I'm experiencing the same problems with another machine. I will have to monitor the situation now, and I would like to run a program that logs when internet connections become slow. I thought about putting something together using at and wget. Does anybody know of some other tool for this that does this out of the box - maybe something with an adjustable request frequency, logging connection speeds etc.?
