• SQL Server Unattended Install through SSH

  - by Samuel

  I'm trying to install SQL Server from the command line through Cygwin open-ssh. The install works when I log onto the server as Administrator and execute the script through a Cygwin shell, but the install doesn't work when I SSH into the machine using Administrator's credentials and run the exact same command. I've already verified that the SSHD process is running as the Admistrator, and I've verified that the install script is indeed starting under Administrator. Is there something different with the terminal in SSH vs. the Cygwin terminal on the machine that would cause this problem? Specifically what's failing is Sql Server install runs for a while then hangs with a MSI error 1622. "Error opening installation log file. Verify that the specified log file location exists and is writable." If I run both installs, I've noticed that they have different authentication id's in ProcMon, but they have the exact same command line parameters. There has to be something in SSH that is causing permissions issues... Any ideas?

• No sound out of headphone port

  - by Thanatos

  I cannot get sound out of the headphone port. Headphones are plugged in, and sound comes out of the internal speakers. Windows behaves normally (sound switches to headphones when headphones are inserted). It did work in Linux at one point, but something changed, we're just not sure what. Rebooting doesn't fix. This appears to occur whether or not PulseAudio is running. Things I've tried: Rebooting. No effect. Booting into Windows. It works properly, so probably not a hardware issue. All of alsamixer. My only controls are this: "Master" Volume bar & mutable, unmuted. Controls volume. "PCM" Volume bar only. 100%. "S/PDIF" Mutable only, currently muted, has no effect. "S/PDIF" Default PCM", Mutable only, currently unmuted, has no effect. Killing PulseAudio. No effect. (It also won't stay dead! Something appears to be restarting it, and I can't tell what, but it is annoying as fuck.) alsactl init 0, no effect. sudo rm -f /var/lib/alsa/asound.state, no effect. General system info: Ubuntu 10.04 LTS Toshiba Satellite T135D-S1324 lspci says I have: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller

• Ruby installed on Ubuntu 10.10 slow on one machine but not other

  - by Aaron Jensen

  I have a machine that was provisioned several months ago. RVM was used to install ruby 1.9.3-p125 as well as 1.9.3-p125-perf. When I compared raw ruby performance to another identical machine the older machine smoked them. For example: ================================================================================ With in-block needle calculation ================================================================================ Rehearsal ---------------------------------------------- detect 3.790000 0.000000 3.790000 ( 3.800895) each 2.410000 0.000000 2.410000 ( 2.420860) any 3.960000 0.000000 3.960000 ( 3.972099) include 1.440000 0.000000 1.440000 ( 1.442862) ------------------------------------ total: 11.600000sec vs ================================================================================ With in-block needle calculation ================================================================================ Rehearsal ---------------------------------------------- detect 10.740000 0.000000 10.740000 ( 10.769366) each 6.080000 0.010000 6.090000 ( 6.106323) any 10.600000 0.000000 10.600000 ( 10.641606) include 4.160000 0.000000 4.160000 ( 4.171530) ------------------------------------ total: 31.590000sec I attempted to reinstall 1.9.3-p125 with rvm on the fast machine and that ruby is now slow. It's as if something changed in RVM, or I installed some package that made compiled versions of ruby perform significantly worse. I know this is a tough question to answer, but what things should I look into in order to track down why the performance has suffered so much? edit I just attempted to install with ruby-build and the version installed was fast. Something rvm is doing to build it in my environment is slow.

• How can laptop keyboard keys be removed and replaced?

  - by Lord Torgamus

  I'm trying to fix a laptop keyboard that has issues with keys on its left side. Just by feel, it's clear that something sticky got under there. There could be something crunchy too, but that might just be the sound of the key's spring releasing itself from the sticky. I don't know the cause because it's not my computer and the owner isn't sure, but I'm guessing soda spill for now. The computer is an HP dv2500. I've removed the keyboard and blown under it but that hasn't helped. I didn't use compressed air because I just don't have any available, but I suspect it wouldn't help with sticky. So, I'd like to pop they keys off and clean with damp cotton swabs or similar. Is there a proper way to remove the keys? I've found some instructions via Google for non-laptop keyboards, but they don't seem like they'd work for me. Alternate solutions to the problem also welcome, but I've been curious about how to remove the keys for some time for other reasons.

• Ubuntu 10.10 - disaster - what other linux for beginner?

  - by A-ha

  Guys, I've tried to install ubuntu (desktop and notebook ed) on my laptop and unortunately I have to say that as despite the fact that installation process supposed to be easy I couldn't finish installation of this system - didn't detect my keyboard or rather lost my keyboard as soon as I tried to switch on/off pad on my laptop. After I've discovered that, I started all over again (this time without touching my laptop's pad during installation) and yes, eventually it get to the end of installation. Unfortunately, when I've tried to switch my pad (sometimes I just do not want to use a mouse) the whole system froze. So I had to restart it with the power button and this time I didn't touch pad at all, plugged in mouse and tried to rearrange taskbars according to my liking (all taskbars on the top side of the screen and auto-hide on) and I gave up. It is so unfinished that I just can't be bothered to use it. I would like to have one linux system on my machine so I started googling and most of the links are to either ubuntu (which I just do not want to touch for now) and suse or commercial versions of linux. I do not really mind paying for something (and having experience with ubuntu I'd rather pay and have something pro then get it free and discover that it's unusable). So could someone please provide short list of linux distros which would be appropriate for a beginner, and I don't mind paying for it, I just want it to be a professional product.

• Best SSD tweaks for Windows 7

  - by Nick Berardi

  I have seen many articles about tweaking an SSD, but many of them seem outdated, or too broad (read all Windows XP, Vista, and Windows 7 general tweaks). And I know that Windows 7 has been specifically tweaked for SSD by the Windows team, so I don't want to do something that was written for Windows XP in mind and end up circumventing something the Windows team has specifically designed in to Windows 7. So my question is what are the best SSD tweaks for Windows 7 that you have found to get the performance out of your drive? I hope to make a comprehensive list in the answers below so there won't be so much disinformation in the forums about what to do and what not to do. Here are a few that I see posted up on the forums alot, and some questions to get the discussion started: Disabling Superfetch. Yes or No Disabling Page File or limiting it to a really small size such as 500 MB. Disabling Indexing. Yes or No Disabling Defragmenting. Yes or No What are your thoughts do you have any that have worked for you? When providing an answer please do your best to back it up with a reason and possibly some documentation from MSDN, TechNet, or another credible source.

• Apache2.2 not responding or logging anything on Win 7

  - by Adam

  I'm having some trouble with Apache2.2 on Windows 7. For over a year it's been running no problem, but all of a sudden requests have just stopped responding. They don't time out as such, the browser just keeps on waiting forever. Nothing is recorded in either the error log (set to debug level), the access log, or Windows' Event Log. The problem showed up when I added a new VHost and restarted, however a syntax check has shown there's no problem with the config (from the little I changed), and the service does actually start error free. I've also disabled VHosts and tried with just localhost. I've tried to telnet to the web server, and it connects, but nothing happens. The prompt just goes blank and I can't type anything, and effectively become stuck. I've ensured there's a rule within Windows Firewall for Apache, and I've even disabled the entire thing just to check it wasn't the cause. Still the same. If I stop Apache however, the request fails immediately. I've uninstalled and reinstalled Apache, in the hope it might magically fix something using the default config, but still no joy. I've tried using a different port but nothing different. Does anybody have any suggestions to fix this? Or to perhaps try and figure out either if it's Apache itself not responding or something sitting between the two that's holding things up? I'm not too savvy on debugging Windows issues like this and I've been searching for hours but not found anything of use to me. Cheers Adam

• How to add "create a new python file" to the registry

  - by Anthony

  I have Python 3.2 on a windows 7 operating system. The other day I thought that it would be convenient to add a link to create a new .py file in the right hand click "new" menu. I had worked with the registry before and looked up how to add an item to the "new" menu, but when I got to the registry under HKEY_CLASSES_ROOT the .py extension key was not there. I only know how to add something to the "new" menu using the extension key. I searched the web, but could not come up with any other ways. Python works perfectly fine, and I don't want to mess anything up by adding the extension key. So here are my questions: Will I mess up python or something else by adding a .py key?( I know it is dangerous to work with the registry, that is why I am looking for a safe solution) If not how can I go about doing this? OR Is there a different way to add "create a new python file" to the "new" menu? If so how can I do it? OR If the only way is very complicated should I forget about it? Thank you in advance. P.S I originally posted on Stack Overflow that they told me to move it over here.

• The Dreaded Startup Repair Loop on Win 7

  - by HighAltitudeCoder

  For most people, upgrading to Windows 7 has been a relatively painless process.  Not me.  I am in the unlucky 1% or less who had a somewhat less pleasant experience.  First, I cloned my entire onto a larger (and much faster) solid state hard drive, only experiencing minimal problems. Then, I bought the Retail version of Windows 7 Ultimate, took a deep breath and... oh yeah, I almost forgot - BACK UP THE COMPUTER.  The next morning I upgraded to Win 7 and everything seemed fine, until... I rebooted the system, the nice Windows 7 launch graphics come up, it's about to launch and AWWW, are you kidding me?!?!  Back to the BIOS splash screen?  Next comes the sequence of failure - attempt repair - unable to repair - do you want to wipe your hard drive decisions. Because I purchased the retail version, a number is provided where I could call Microsoft Tech support.  When I did, they instructed me to click "Install" from my installation CD, which did not work.  When I tried the "Upgrade" option, it reaches an impasse, telling you that yoiu have a newer version of Win 7, and thus cannot Upgrade.  If you choose "Install" you willl lose everything... files, programs, EVERYTHING.  Or at least this is what it tells you.  I was not willing to take the risk. To make things worse, I had installed a new antivirus software application before I realized my system was unstable (Trend Micro Titanium Internet Security), and this was causing additional problems. One interesting thing, and the only saving grace as it turns out, was that my system WOULD successfully reboot into the OS if I chose to restart it, rather than shut it down.  If I chose to shut down, I would have to go through the loop again until I was given the option to restart. As it turned out, I needed to update my BIOS.  I assumed that since I had updated my BIOS a long time ago to settings that were stable under Windows Vista Ultimate x64, I incorrectly expected Win 7 to adopt the same settings and didn't expect there to be any problems.  WRONG. My BIOS had a setting to halt the boot cycle if various kinds of errors were detected.  Windows Vista didn't care about this, but forget it under Windows 7.  I turned immediately corrected that BIOS setting.  Next, there were the two separate BIOS settings: enable USB mouse and enable USB keyboard.  The only sequence of events that would work were to start my reboot process over from stratch with a hard-wired non-usb keyboard and mouse.  Whent the system booted under these settings, it doesn't detect any errors due to either the mouse or keyboard, and actually booted for the first time in a long while (let me tell ya, that's an amazing experience after fiddling with settings for two entire weekends!) Next step: leave your old mouse and keyboard connected, but also connect your other two devices (mouse, keyboard) that use USB connections.  During the boot cycle, the operating system will not fail due to missing requirements during startup, and it will then pick up the new drivers necessary to use your new hardware. If you think you are in the clear here, you are wrong.  The next VERY IMPORTANT step is to remember to change your settings in the BIOS upon next startup.  Specifically, yoiu will need ot change your BIOS to enable USB mouse and enable USB keyboard input.  If you don't, Windows will detect an incompatibility upon the next startup, and you will be stuck once again in the endless cycle of reboot/Startup Repair/reboot/Startup Repair, without ever reaching a successful boot. Here's the thing - the BIOS and the drivers registered in Win 7 need to match.  If they don't, you're going to lose another weekend worrying and fiddling, all the while wondering if you've permanently damaged your hard drive beyond repair. (Sigh).  In the end, things worked out.  I must note that it is saddening to see how many posts there are out there that recommend just doing a clean install, as if it's the only option.  How many countless poor souls have lost their data, their backups, their pictures and videos, all for nothing other than the fact that the person giving advice just didn't know what to do at that point? My advice to you, try having a look at your BIOS settings first and making sure Win 7 can find your BIOS settings, and also disabling in your BIOS anything that might halt your system boot-up process if it encounters errors.

• WINDOWS: Your computer hangs. You can windows + R (run dialog) but performance is so halted taskMGR

  - by John Sullivan

  The question is, what process are available to try to recover from total system instability before pulling the plug when we can do nothing but programs or batches in the path from the run dialog (windows + r key), and performance is so dead that taskMGR / procEXP / other programs with visual guis are not usable? I am not a windows expert, but ideally someone out there has written a program that does more or less stuff like this: Immediately set (or perhaps I can set from the run prompt) its priority to extremely high, evaluate performance bottlenecks. E.g. is CPU 100%? If so identify offending program(s) or problems. Attempt / log fixes, then provide crude feedback asking the user if his performance has stabilized enough to abort, wait a few seconds, if no feedback continue, etc. etc. Eventually try to do any "system cleanup" if the program decides it cannot recover and perhaps finally provide a series of beeps to the user, or what have you, to say "OK, I give up, time to pull the plug". Ideally create a log, when able. These kinds of horrible hangs are a situation where surely trying something, anything, is better than nothing -- as long as that something is intelligent -- when the alternative is ripping out the power coord. Again, I am not a windows expert, so perhaps there is a much more elegant "hands on" approach I am not aware of.

• Software/hardware to build video streaming server?

  - by Sasha Yanovets

  I am looking for a video streaming server solution, something like online TV server, with ability to make live broadcasts in the internet. What software could you recommend for that? What kind of hardware it should run on, should be there anything special? I am looking for a solution that could be scaled up to at least 1000 simultaneous users online with good resolution of video. I think it is good to have general answer on what direction to choose. But here more details on my specific case: I just looking for a solution almost from scratch. We have some video content that we've produced, but it is not delivered over internet yet. We do not tied to any particular vendor for now. We want to make 24 hours of steaming three 8 hour blocks with change of content every day. We want the ability to make regular live broadcasts. I guess we will need to have several options of streaming quality (low ~56 kb/s mid ~273 kb/s). Some terms just foreign to me (like play-truncation rate), if you could point out what parameters we should avare of, it would be great. Uplink to the internet is to be determined. We plan to start from something and scale up on the way. If you are already have some kind of media streaming server, just describe its configuration here (hardware, OS, software), peak number of concurrent users it serves. I think it could help people approaching this task.

• need to bring back win 7

  - by user290513

  I like making music and playing games and occasionally do some Photoshop. I had a windows 8 computer but my mouse pointer always got stuck, so to try out something new I installed Ubuntu. here is how I installed it: Went to advanced statup options clicked on "use a device" after plugging in my bootable USB with Ubuntu replaced my windows 8 and installed Ubuntu 14.04 LTS I hope I did it correctly though. So after a few months I could've really find out a good Audio Production (not LMMS, because I use Stagelight) software nor something that could be familiar to the UI of Photoshop. So I decided to bring back Windows, but because of the bad experience of 8 I thought about bringing back win 7 So I used an app named WinUSB to make my bootable USB drive after formatting it to NTFS in GParted But when I go to my grub menu, my USB doesn't show up and my PC being a UEFI device. I don't know how to get to the bios of my device. Can somebody tell how to install Windows 7 completely and deleting Ubuntu or at least give me a link to a tutorial. I have a netbook: it is an Acer Aspire One 725. I'm fine with using commands in terminal and another thing that my laptop doesn't have a CD drive or reader, I can't put a CD inside

• Which steps are required to avoid my server being considered as spam sender?

  - by Cyril N.

  I'm looking to set up a webmail server that will be used by a lots of users that will receive and send emails. They will also have the possibility to forward emails they receive. I'd like to know which steps are recommanded/required to indicate to others Mail services (GMail, Outlook, etc) that my server is not used as a spam sender (disclaimer : IT's NOT ! :p) but a legitimate one. I know I have to define a SPF TXT records for example, but what others steps would you recommend me to do ? For example, is there a formula like having a proportional number of servers based on the amount of email sent (for having a different IP address) ? (something like sending a maximum of 1M emails / per IP / per day ?) Something else I'm missing ? I tried to search online, but I mostly find how to avoid emails sent with scripts (like PHP) being put in the SPAM folder. I'm looking for a server/dns configuration side. Thanks a lot for your help/tips, I appreciate !

• Configuration of Server root email - Change Address and Name on outgoing email

  - by JTWOOD

  As a newbie Postfix user, I've gotten so far and now I am stuck with a SMALL problem. I would like to configure my local network servers to send alerts and like using the following: 1) From address: [email protected] 2) From name: Hostname I can get #1 to work fine using smtp_generic_maps The problem is that on my email client, the name is listed as "root" - as in the header shows the following: Date: Sun, 29 Jul 2012 13:21:01 -0400 (EDT) From: [email protected] (root) To: undisclosed-recipients:; I'd like to change it to "From: [email protected] (Zeus)" I imagine that this can be done in the headers_check, but so far I haven't gotten anything to work and before I waste a ton of time trying to get this to work, I'd like to make sure I am on the right track. My aliasing and genericmaps are set up correctly (As far as I can see and know - the results are correct!). I just want to change that last bit in the From field to reflect the hostname. I would also like to add something in the subject of the outgoing messages for easy filtering - something like Subject: [Zeus.domain] - "Original Subject" Any suggestions are much appreciated. Thanks!

• Dosbox USB print Windows 8.1 64Bit

  - by eCronik

  Worked fine until I've upgraded to Windows 8.1 as well as made the mail programm working (had to get a windows live ID and have to type in a password now, when starting Windows). I did set the USB printer to lpt1 on the local Windows 8 computer and another XP computer via LAN to lpt2 the same way with the same printer on the Windows 8 computer. But now it doesn't work anymore from the Win8 one (where the printer is plugged via USB). Tried already deleting lpt2: on the XP one, as well as lpt1 on the Windows 8, resetted it. Not working... :-( I tried also net use lpt1: \server\printer password "\user:Ute Berger" /persistent:yes of course with the correct server and shared printer name as well as net use \server\printer "\user:Ute Berger" password /persistent:yes . This is the name displayed as a user now. But in C:\users it is named Benutzer1. Tried this one also. Nothing worked. What could be the problem here? What's strange is that when I type "net use lpt1:" on the XP, I get another error (67 - The networkname wasn't found) than trying something I didn't set up like lpt2 (2 - The system can't find the file). Could this be a possible problem as even if deleted something is left blocking on the Windows 8 computer? Please help me - I tried for hours today but all I've got was frustration... Regards Tim

• Computer randomly shuts itself off

  - by Decency

  I have not been able to determine a pattern for why this happens, despite my best efforts. I've attempted to run it on full power with Prime95 and this doesn't trigger a restart. Generally the restarts occur while I'm playing games, watching videos, or even just having multiple tabs open in a browser. However, I often play processor intense games for hours without any restarts occurring, and sometimes they'll happen 3-4 times in an hour during less intense activity, so I don't think that is the problem. I imagine it has something to do with overheating or power consumption so I've been monitoring CPU temperature and cleaning with compressed air, but the problem keeps happening. I don't know how to track power consumption, and assume that this is the problem. Whenever this occurs, the sound gets stuck in a short loop of whatever was playing at the time, though restarts also occur when nothing is playing. Here is a screenshot of temperatures: and under load: Here's the parts list: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10546754 As shown in the list, the case includes a 585W Power Supply, which I've been told should be plenty. I built the computer myself with a friend's guidance but it's very possible I did something wrong. Right now I'm looking into ensuring that I have the latest drivers for all components. Any help would be appreciated- thanks.

• Have to run auto-negotiate between clients and switch - "old" switch works fine - "new" switch results in "port flapping"?

  - by ConfusedAboutSwitching

  I need some help understanding a problem we're having at work: We run Altiris/Deployment Solution and have to use auto-negotiate between client systems and our switches (Altiris apparently requires this for imaging, PXE boot and other functions). We have several areas with old wiring (Cat 3 & Cat 5) that have old 10/100 Cisco switches in them - and we can set these systems up to "auto/auto" (auto-negotiate on both the NIC and the switch port), and everything has been working fine. But - our networking crew changed out a couple of old switches for 10/100/1000 Cisco switches, and now - they are claiming that "auto/auto" won't work because the switches can't auto-negotiate the way the old 10/100 switches did - and that if we try to set the new gig switches to auto-negotiate, the switch port starts "port flapping", and shuts the port down. But - if we put the old switch back in - they work using "auto/auto" just fine - no port flapping. The networking crew is telling me that the problem is that we're putting "new switches" on "old wire", and that the old cabling can't/won't support the auto-negotiation with these new switches....??? There's something about this that doesn't make sense to me - can someone explain this to me? Or is our networking crew just doing something wrong in the configuration of these new switches? While will the old switches work "auto/auto", but the new switches won't?? HELP!!....and Thanks!! M

• VMWare Server modifying files related to paused VMs, is this expected?

  - by David Spillett

  While refreshing the backup of a VM used for testing, I experienced the following warning from tar: tar: /VMsR0/cli_noddyco_test/VM2K8_32_web.vmem: file changed as we read it The VMs in question were paused at the time. My first though was that I'd mixed up the machines and was trying to backup something that was still actively running. To be sure I unpaused and properly shut down the VM, and the vmem files that tar reported changing vanished as I would expect. Is it normal for VMWare Server to touch or alter files for paused VMs like this, or is there likely something amiss with our setup? If this is expected behaviour, is just touching the vmem file (and so altering the last modification date without actually changing content)? If it is normal for files relating to paused VMs to be updated I shall have to revise our backup procedures to make sure the VMs are fully shut down fully rather than just pausing them (this isn't a problem, but it seems strange and I'd prefer to understand what VMWare is doing and why instead of just dismissing it as "one of those things" and working around it). For further detail: the host in question is VMWare Server version 2.0.2 running on 64-bit Debian/Lenny, and that VM did not have a snapshots at the time. We have backed up paused VMs this way in the past with no such warnings from tar.

• Advice for UPC/Surge Protector in home office

  - by Fred

  I'm just starting out as an independant developer, mostly Unix stuff with some Windows thrown in occasionally. I've been running two machines, a linux and a windows dev machine. Long story short, we had a bad storm come through last week and I unplugged one machine, forgot to unplug the other and the p/s and mobo ended up dead. Luckily I backup to an external service religiously (rsync.net for anyone interested), so there was no loss in data, but it did show me a glaring hole in my current setup, namely, lack of UPC and Surge Protection (this has honestly never been an issue before). Can anyone recommend a UPC/Surge Protector for a home office? It only needs to support a single machine (I opted to use vmware instead of rebuilding that machine), but it's a quad core Phenom 2 with a 1k watt p/s. This is outside my experience so I thought I'd get some input from others. I'm looking for something that's reasonably priced and does the job reasonably well. I don't need absolute 100% uptime, just something to protect my PC better than it is now.

• Start Chrome by command line, but adding some arguments to make it login into your Google account automatically

  - by jim

  Is there a way to start Chrome calling it from the command line (using Linux), but providing it some argument to make it login into some Google account automatically? I'm looking for something like google-chrome -account foo -pass bar that I can easily put in a bash script later. A little background: I have a laptop connected to my TV, which is currently using just a mouse for user interaction. There's no google account logged in by default, and that's the way I want to keep it, so my kids can't come across videos and pictures in google and youtube that they are not supposed to see (e.g.: adult content, or anything marked as not appropriate for kids by the google's safe search filters). The bad thing about this is that there are some music videos in youtube that requires you to be logged in to see, usually those we (the adults) used to sing when playing karaoke... as the only input available is a mouse, I'm looking for a way to start with my google account without having to type the whole thing usin the on-screen keyboard. You may think "Why you can't use the keyboard, if the laptop is right there?". Well, it's in a kind of uncomfortable position - too high for me without a chair or something, as it's right above the furniture in where the TV is located. Is there a way to make this scriptable? If not, do you know any other workaround? Note: using the remember me after logging off or alike options are discarded, as the safe-search chrome version must be always the default version to run.

• Computer won't start after installing new video card

  - by Vercas

  So, 1 year and 340 days ago I bought a desktop computer. Since then, it has served me well. But lately, I wanted an upgrade, so I bought a new video card. I documented myself about the compatibility, and it is okay. So I opened the case, cleaned up that... dust elemental living inside of it. Unscrewed the plastic thingie on the outside to unscrew the old video card. Because of the stupid arrangement of the ports, I had to unscrew the motherboard to unplug it. So I unscrewed it, removed the old card, put in the new one, moved the motherboard back, screwed it back in, screwed the video card on the holder... thingie, and screwed the plastic thingie back in. Everything went smoothly, nothing had to be forced in/out. I connected the external power supply, closed the computer case, put the tower back in it's place and all the cables back in. When I pressed the power button, the LED turned... some color I can't distinguish. It stayed that way for a second, and then it went off. I tried a bunch of things, including permuting the external power supply arrangement (1 connection, 2 connections and no connections), with no success. And here are some of the specifications: Motherboard manufacturer: Asrock Processor: AMD Athlon II X2 3.0 GHz RAM: 2 x 2GB (had only 1 initially, bought the second plate a bit later) OLD video card: AMD Radeon HD 5450 NEW video card: Gigabyte nVidia GeForce GTX 650 GPU, 1GB GDDR5 128bit PCI-E, Dual-link DVI-Dx2 / HDMI / D-Sub Power supply: 450W + all the requirements I managed to find on the internet are met (+12V 18A or something) More specific information is stored... On that computer. If required, I may open the case again and read the stickers to find more specific information. I can also provide photos if necessary. Any ideas? Suggestions? Something? :|

• Are ZFS snapshots + S3 a viable backup system for several VMs and general fileserver storage?

  - by AllanA

  I've been tasked with setting up a backup system for my small office (around 12 people). Most of our production stuff is on the AWS cloud, so what I need to back up are some small office/development files (under 100G right now), plus our operational VMs and development, which round out to a bit under 1T. I just need something reliable, convenient, and straightforward. I'm comfortable with Linux, FreeBSD, and to some extent Solaris 10, so I'm leaning toward a full server rather than an appliance system ala Openfiler or FreeNAS. What I'm contemplating is a small fileserver for general storage and nightly backups of the virtual machines, followed up by an offsite backup to Amazon's S3 storage service. It'd be the usual incremental backups nightly and full backup weekly. My question is if using ZFS snapshots, both locally and dumped to S3 via 'zfs send [-i]', is a viable backup tool? Or should I stick to using Duplicity, or some other method entirely? ZFS snapshots on the internal fileserver/backup machine sound like a perfect way to provide quick and convenient data recovery, so I'm likely to go with that for local redundancy. (If you folks see scenarios where relying on ZFS snapshots would be worse than a more traditional archiving backup, feel free to convince me.) But are snapshots flexible enough to lean on for recovery from the loss of my backup server? Or am I better off with something more traditional? (feel free to recommend free or commercial backup solutions you favor.)

• How can I get multiple video cards to work on linux?

  - by user17943

  I installed fedora 12. I have 2 ATI cards that I used to use on windows to run 4 monitors. A recurring problem has been to get them detected in linux. Only my secondary card is picked up linux. When I manage the displays it detects the 2 monitors connected that card. What are the specific steps I should take to get the second card detected? Supposedly there is a tool system-config-xfree. I don't have it, yum can't find it. Also I heard it has something to do with editing some xorg.conf file or something to that effect. I have absolutely no idea how to find the "bus id" of my card, or lookup the horizontal refresh rates, etc.. I would probably have no problem following the documentation & editing the file if I knew a good way to find these values. Someone also suggested installing linux twice and saving the xorg.conf it generates each time (with different card each time) and then merging the two by hand. That is like killing a fly with a hammer though, when I do this again and again in the future It'd be nice to not have to take twice as long. Thanks

• PHP application failed to connect after a network plugged back in

  - by tntu

  My data-center appears to have had some issues with their network and thus my server has suffered from on an off network connectivity for about an hour. After the connection has been completely re-established my code still kept reporting the same issue over and over until I have restarted the service. The code is a simple PHP code that loops forever checking the Apple feed-back server and then sleeps for a few minutes and then it begins all over again. Now I understand the error being generated if the network is down but once it got back up why did it continue until I have restarted the code? Does PHP have something that needs to be re-initialized or something??

• Simple, centralized user management on a small LAN - NIS or LDAP?

  - by einpoklum

  I'm setting up a small LAN for my team. It will, for all intents and purposes, not be connected to any external networks. I would it to have centralized control of user accounts (at least, I think I'd like that; I'm also considering using puppet, so theoretically I could just push /etc/passwd changes, or something). The number of machines is fixed, but not very small. Mostly they're 'attached' to a single user, but sometimes people work remotely on someone else's box; and there are a couple of servers. I've read this question, but my scenario is much simpler (even simpler than in this question) and I'd like to do something (relatively) quick, with not much hassle, but not a dirty totally-insecure hack. Is NIS relevant for my scenario? If not, what's the most hassle-free way to set up LDAP (or LDAP+Kerberos) to achieve the same? Notes: I have no experience with setting up either NIS or LDAP. We use Debian-flavored Linux distributions, mainly Kubuntu 12.04 (not my choice, but that's the way it is).
