  • Problems with Startup after Script runs to Shutdown Windows 7 PC

    - by Toby Allen
    I have a simple .bat script to shutdown a kiosk style machine in our work shutdown -h -f this hibernates the machine and I have it running each evening as a scheduled job. However my problem comes when I turn the machine on again. The first time I press power it starts up and then immediately hibernates again, like it runs the script a second time. the second time I press power it stays up. Any suggestions on how I can avoid this?

  • Can Amazon VMs be used as Active Directory domain controllers?

    - by mrdenny
    I've got a client who wants to move his companies servers off site. As he is only a 10 person company I'm looking for some pretty in-expensive options. One option is the smallest of the Amazon cloud machines. The question becomes can I make one of these machines a domain controller? Cost wise the Amazon machine is cheaper than the power costs of keeping a server (or a PC) up and running in his home office 24x7 thanks to the high cost of power in Southern California.

  • After my laptop wakes up from sleeping/hibernating, the LCD/brightness is very low. How can I set it to default?

    - by meder
    In Power Management Preferences, On AC Power tab, I have brightness to 100%. "Dim display when idle" is not checked. I know for sure my LCD brightness is capable of going higher, because if I hit Fn and F7 then it resets the monitor brightness and settings for a few seconds, but the resolution breaks and then the brightness goes back. PS: OS is Debian Lenny ( I set the tags but for clarification ) and laptop is a Thinkpad.

  • Hardware for multipurpose home server

    - by Michael Dmitry Azarkevich
    Hi guys, I'm looking to set up a multipurpose home server and hoped you could help me with the hardware selection. First of all, the services it will provide: Hosting a MySQL database (for training and testing purposes) FTP server Personal Mail Server Home media server So with this in mind I've done some research, and found some viable solutions: A standard PC with the appropriate software (Either second hand or new) A non-solid state mini-ITX system A solid state, fanless mini-ITX system I've also noted the pros and cons of each system: A standard second hand PC with old hardware would be the cheapest option. It could also have lacking processing power, not enough RAM and generally faulty hardware. Also, huge power consumption heat generation and noise levels. A standard new PC would have top-notch hardware and will stay that way for quite some time, so it's a good investment. But again, the main problem is power consumption, heat generation and noise levels. A non-solid state mini-ITX system would have the advantages of lower power consumption, lower cost (as far as I can see) and long lasting hardware. But it will generate noise and heat which will be even worse because of the size. A solid state, fanless mini-ITX system would have all the advantages of a non-solid state mini-ITX but with minimal noise and heat. The main disadvantage is the read\write problems of flash memory. All in all I'm leaning towards a non-solid state mini-ITX because of the read\write issues of flash memory. So, after this overview of what I do know, my questions are: Are all these services even providable from a single server? To my best understanding they are, but then again, I might be wrong. Is any of these solutions viable? If yes, which one is the best for my purposes? If not, what would you suggest? Also, on a more software oriented note: OS wise, I'm planning to run Linux. I'm currently thinking of four options I've been recommended: CentOS, Gentoo, DSL (Damn Small Linux) and LFS (Linux From Scratch). Any thoughts on this? Any other distro you would recomend? Regarding FTP services, I've herd good things about FileZila. Anyone has any experience with that? Do you recommend it? Do you recommend something else? Regarding the Mail service, I know nothing about this except that it exists. Any software you recommend for this task? Home media, same as mail service. Any recommended software? Thank you very much.

  • VLAN issues between linux kernels 2.6 / 3.3 in an ESX / Cisco environment

    - by David Griffith
    I shall attempt to explain an issue I have encountered - I have a VM running on esx 4.1 with an interface connected to VLAN800 via an access port on a cisco 3750. It runs linux - kernel 2.6.24, and has about 5 to 10 Mbit of chatter on 10.10.0.0/16 and various multicast addresses to look after. I needed to isolate certain devices from certain other devices on the network, with all of them having to talk to that one VM. No, the address space can't be separated, nor can the networks be easily vlan'd apart. The software on the VM listens to one interface only. Private vlans appear to be the way to go. So as a test, I built a bridge on the VM that globs together the vlans as needed. All good, everything works as expected. But occasionally (sigh) there's some latency that trips up a couple of profinet devices on the network because, you know, you're not really supposed to trunk real-time protocols around the place willy-nilly. I shift it to our test/backup server - works nicely, but I don't want it to be running on the test server as we muck around with that a lot. So I says to myself, "I'll put it on a new VM for testing and tweaking." I download a small linux distro with kernel 3.3, and install as a new VM with a the vlans as separate interfaces for testing. I power up the testing VM - ok. I bring up all the separate interfaces - ok. I can ping the production VM, see all sorts of traffic going past with tshark, etc. I build a bridge and put the primary vlan on it - the production VM running 2.6 immediately loses its multicast traffic - Unicast is fine. (?) I shut down the bridge - still no multicast traffic (!?) I power-cycle the production VM(!?!?) - multicast traffic returns. I trunk everything into the testing VM and create vlan interfaces under linux instead - same result, as soon as I start the bridge.... no multicast on the production VM. Ok, so I take a break and leave things alone. I decide to play with a couple of ubiquiti bullet radios - I'm testing various firmware as a side project. I flash a radio with Open-wrt-12.09. I enable a trunk on a port on a cisco on our network so I can muck around with multiple vlans and SSIDs I power up the radio and connect - ok. I create a vlan interface from the trunk.... the same vlan as the production VM wayyyyy over there, three cisco routers away. Ok. I bridge the vlan interface to the wifi interface and immediately get a phone call. The production VM has (suprise!) lost its multicast traffic. Again, nothing comes back until I power-cycle the VM. What the hell is going on?

  • Safely reboot prior to recovering data

    - by ELO
    What is the safest (without additional writing to the disk) way to power down computer whose deleted files you want to recover in order to boot from rescue medium? In case of a desktop computer, plugging off the power cord looks like the most direct solution, but are there possible side-effects, apart from losing unsaved data? More problematic seems the laptop, with removing the battery being the equivalent, but is it a good idea overall?

  • USB devices don't work after restoring from Stand By

    - by Steve
    Hi. I'm running Windows XP SP3 on a NEC Versa L1100 laptop. If I wake my laptop up from Stand By, no attached USB devices will function. Device Manager shows all USB entries to be working properly. There is an option to "Allow the computer to turn off this device to save power" in the Power Management properties of USB entries. Is this causing the issue or something else? I have the latest drivers for my motherboard installed.

  • Computer not turning off after windows shuts down printer driver

    - by Confused
    The power is not shutting off my computer after windows shuts down. Windows shuts down and I hear my computer case "click" but the power and fans all stay on. This seemed to start after I installed the canon pixma printer driver and software from their website. I have uninstalled the printer software from "uninstall program" and deleted the printer from printers. I have even stopped spool service and deleted printer following this post, the printer drivers did uninstall. How to completely remove printer from Windows 7

  • Is data=journal on a separate device on Ext4 as good as using a RAID controller with battery backed cache for file system consistency?

    - by Jeff Strunk
    It seems to me that data=journal prevents file system inconsistency in the case of power failure. Using it with a dedicated journal device mitigates the performance penalty of writing the data twice. A power outage would still lose the data that is currently being written to the journal, but the file system on disk would always be consistent. If that amount of loss is acceptable, is a RAID controller with battery backed cache really worthwhile?

  • Building a backup server

    - by user8181
    One of my older motherboards broke and I'm planning to use the remaining power supply, hard drive and case to build a backup server. I want to buy a new motherboard and CPU that can be used 24x7 and wont break down in a few months. So the question is, do you have any recommendations on any reliable motherboards and CPU for a backup server? Processing power is not a huge issue.

  • Finding a cause of shutdown/sleep

    - by user1188570
    My server running is Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux. About once a day, sometimes once every two days is shut down - It isn't really shut down, it seems like its sleeping - Power button is blinking, but I cannot boot it by clicking on power or reset button, I must pull electricity out and plug it back in, then I can boot it. What could be the cause of this? How can I fix this?

  • Emulator batteryService not working

    - by user568551
    So i've got a 1.6 emulator running. I have a receiver with action power connected and disconnected filters. when i connect to the emulator through telnet and issue the power ac on or power ac off command, logcat shows: 01-11 21:33:01.096: ERROR/BatteryService(67): Could not open '/sys/class/power_supply/usb/online' 01-11 21:33:01.104: ERROR/BatteryService(67): Could not open '/sys/class/power_supply/battery/batt_vol' 01-11 21:33:01.104: ERROR/BatteryService(67): Could not open '/sys/class/power_supply/battery/batt_temp' and my receiver does not get activated. It was working just fine yesterday and now it does not. I tried reinstalling the AVD, and also deleted and reinstalled the SDK from the SDK manager. Works fine in my 2.2 emulator. Any ideas?

  • New Computer Build Questions

    - by MJ
    I'm in the process of gathering parts and specs for a new machine. I wear many hats, so the machine needs to do a lot. I need at least 2 monitor support, if not three. I also play many online MMOs (wow, aion, war hammer, etc), along with some freelance programming projects. I already have a case which is very large, so it will fit anything. I have 2 other SATA HDs. They are more for storage and basic programs. I feel that the best improvement could be done with a solid state HD, true or not? I'm more of a software/programming guy, so ANY input at all on improving this system build would be appreciated. I have a few questions with this list. AMD or Intel? I don't know enough about either to choose what would best fit me. Thanks! **EDIT: Thanks for the input everyone! Here are some answers: I do a lot of programming and gaming, so I do need things for both. The newer video card covers the gaming aspect, as well as allowing me to have many monitors. (hopefully upgrade to dual 30' or more) I don't need any additional HDs at this time. I have a SATA 160g and 120g from my previous computer, and a NAS system with over 2TB of storage on the homenetwork. I just wanted a fast HD for OS/programs/games. With the memory. I have used G.SKILL before in 2 system builds. It's done excellent for me in them. Very stable. **EDIT2: Made some additional changes. Lowered the power supply down to 750, which saves me more $$. Also changed the SSD to 2 WD 650G HDs.

  • How can I troubleshoot a "Hardware Malfunction" blue screen?

    - by AaronSieb
    My computer has suddenly started crashing to a blue screen with the following text: hardware malfunction call your hardware vendor for support *the system has halted* The crash occurs randomly during normal use. I have thus far always been able to reproduce it by transferring the contents of a large folder... But I'm not sure if this is caused by the file transfer, or simply because the transfer takes long enough for something else to trigger it. A bit about my hardware I have an dual core Intel CPU, and Asus motherboard. Video card is by nVidia, and connects via PCIe. My hard drives are in pairs, and connect via SATA to a RAID controller on the motherboard. They are configured to use a RAID0 configuration. What I've tried so far There is nothing in the Windows Event Log. WhoCrashed was unable to find any crash records. ScanDisk runs to completion (it launches prior to Windows load) and reports no errors. MemTest reports no errors (to 200% coverage). System temperatures are in the range of 40 to 50 degrees Celsius, with video card temperatures in the range of 60 to eighty degrees Celsius. I have stripped the system down to a minimal configuration (hard drive, video card, one memory module, motherboard, CPU, power supply). The problem still occurrs. However, this has allowed me to rule out a few components: It is not the video card because the problem still occurred after replacing the video card another one I had on hand. It is not the hard drive or anything software related because the problem occurred after a fresh installation of Windows on a replacement hard drive. It is not the hard drive cables because I replaced those with new ones and still had the problem. It is not the power supply because the problem still occurred after replacing the power supply with another one I had on hand. It is probably not the memory because I've tried three different memory modules in three different memory slots and was still able to replicate the issue. Is there anything I can do to confirm what's causing the issue? At the moment it seems as though it must be either the motherboard or CPU, but those are both difficult components to replace... In addition, both components are relatively new (two to three years old). I will gladly edit in any additional information I can get my hands on, and/or focus the question as I can find more details...

  • New graphics card (GTX 760) slowing down entire PC

    - by Cayetano Gonçalves
    My new graphics card is making my PC totally unusable. It boots up really slowly, and when the windows screen comes on, the mouse lags really far behind. Nothing opens at a normal speed. However, when I put in my 5-year old graphics card, it all works fine. I'm currently using a Foxconn Renaissance LGA 1366 Intel X58 ATX Motherboard, Intel Motherboard Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Processor, and a EVGA SuperNOVA 850G2 80PLUS Gold Certified ATX12V/EPS12V 850W Power Supply . I know it can't be the power supply, because I just bought it today to try to fix the problem. I've also installed the newest version of BIOS available for my motherboard. I've also seen extreme variations in CPU while the new graphics card is in, and when the old graphics card is installed, it is much calmer. Any thoughts?

  • OEM Office 2010 without media - how to reinstall?

    - by Bryan
    I have recently purchased a new office desktop PC from Dell with OEM version of Windows 7 Pro and Office 2010 Pro. One of the reasons I always use Dell is that they always supply installation media CDs or DVDs, unlike some other companies that just give you ISO images on the hard disk that you have to burn yourself. This is the first PC I have purchased with Office 2010 Pro (OEM), and I was disappointed to see that Dell don't ship out any installation media for office 2010, they just supply a piece of card with the office pro product key printed on it. If the HDD fails completely and I have to perform a clean installation, how can I re-install office? Can I download the trial version of Office 2010 and install that, then offer it my product key? Bearing in mind that the product key is an OEM product, not a retail product, would this work?

  • Using Credentials with network scanners

    - by grossmae
    I'm testing out both Tenable's Nessus scanner as well as eEye's Retina for scanning network devices. I am trying to supply credentials to get deeper, more accurate results, however there seems to be no difference in the results whether I supply the credentials or not. I've read the documentation and it seems like I've tried all the logical settings in the Credential options. I've submit along with usernames and passwords for many different accounts and types of accounts (both SSH Credentials and Web Application Credentials) on the devices as well as their respective domain names (when applicable). Is there possibly a good test for either (or both) scanners to tell where these credentials are being provided (if at all) and if any of them are successfully getting authentication?

  • Complete machine freezes...at a loss

    - by user28818
    Guys, We built around 12 machines a few months ago to run Ubuntu. They each have the following specs: ASUS Z8NA-D6 motherboard Dual quad core Intel(R) Xeon(R) CPU E5520 @ 2.27GHz OCZ Mod Extreme Pro 500W power supply 12 GB Kingston RAM Nvidia GeForce 9800 GT graphics card My machine ran well for awhile. However, it started experiencing random lockups. These lockups are not X lockups, they are complete system freezes. The nic stops responding, the magic sysrq buttons won't work. The machine is dead. I first suspected RAM. Memtest86 didn't find anything, but I replaced the RAM anyway. Still, lockups. So I replaced the graphics card. Still, more lockups. They became more and more frequent and started to happen 2-3 times a day. So I replaced the motherboard and power supply in one fell swoop. Suddenly, no more lockups! Woohoo! Except, a week later, in the morning, the machine wouldn't wake up. I reset it, started it up, and the log files showed the last entry at around 11 pm the evening before. This has started occurring with more frequency...now just about every morning I come in, the machine is locked up, and has been since the night before. Yesterday, in the 3 weeks since I replaced the motherboard and power supply, the machine actually locked up on in in mid-work. This is the first time since replacing the two (MB and PS) that this happened while I was using it. All others occurred while I was away. I'm at a loss. Nothing is in syslog or message that would indicate a problem around the time of the lockup. Temps are good...I use lmsensors to monitor and have a script that writes the output to file every minute. They never get that high. The only thing I haven't replaced at this point is the case and the harddrives. I doubt either could be the cause. What would you do if you were in my shoes? Is there a troubleshooting approach I'm missing? For the record, all of the other machines, all eleven of them, don't have any problems. They're all running the same version of Ubuntu (Lucid) that I am. Thanks!

  • PC won't boot with 4 prong CPU connector connected. Motherboard or CPU dead - which one? Both?

    - by scrot
    In the middle of use, my computer shut down. I tried to turn it on but it maybe comes on for half a second, shuts down, then flickers again very quickly about 2 seconds later before giving up completely. So I took everything apart and nailed it down to the power supply, the mobo, or the CPU. I had an extra old power supply around, hooked that up and it had the same problems, so that can't be it. When the 4 prong CPU connector is not connected, the motherboard 'functions' in that it stays on and runs the heat sink etc. Throw in the 4 prong connector and that's when it doesn't stay on. So it must be the CPU, right? Motherboard: ASUS P6X58D CPU: Intel i7-920 Bot are under warranty (supposedly) - should I get both replaced or what?

  • Computer stopped working (ASUS P5GD1-VM)

    - by Gordonrjones
    My computer stopped working the other day. I came down and it was kind of chirping away. Then, when I restarted it, it only did the same thing. I unplugged everything not needed and it did nothing at all. I thought maybe the power supply wasn't working, but when I took the cover off the green light on the motherboard was on and the power supply is making a little buzzing sound. But nothing happens when I turn the computer on, other than the green light on the motherboard flickers a bit. I checked the memory in other computer and it works fine. I'd love to be able to fix this with as little cost as possible. Can someone here help? P4-640 (3.2E GHz, 800 FSB, L2:2MB, EM64T, HT)

  • "Permission denied (publickey)" error when ssh'ing to Amazon EC2 Debian AMI 05f3ef71

    I have launched a Debian system using AMI 05f3ef71 in Amazon EC2, but I have no lock connecting to it using SSH as suggested in "Connecting to Your Linux/UNIX Instances Using SSH". I tried several user names: ec2-user, root, debian... None of them worked. I always get a Permission denied (publickey) error message. Using ec2-get-console-output instance_id as suggested doesn't work either, it requires option "-K". If I supply it, I get the error message Required option '-C, --cert CERT' missing, but I have no idea what to supply there. Port 22 is opened on the affected instance. Does anyone have an idea what I could try to log in to my instance?

  • One motherboard crashed. Changed and wants to crash again

    - by CoachNono
    My computer started to freeze randomly. I was pretty sure it was the hard drive that was starting to fail. Before I could change it, the motherboard was completely dead. I bought the same one and reinstall it. Everything went working well until my computer started to freeze again and doing the same problem has before. I don't want my motherboard to burn again and I'm really wondering what can be the problem... Could it be the power supply or the video cards that burned the motherboard ? I tested the voltages of the power supply and they seemed fine... The computer worked as is for four years...
