  • Advise about quick/full format

    - by ile
    Is it virus-safe to do quick format of hard drive? I want to format disk that was infected and install windows 7 on it, but I am not sure if Quick Format is secure enough. I am aware that it does not delete data but pointers to it, so I wonder if it is possible that virus activates from that data? Thanks

  • 'No volume found' on Windows 7 VM (VHD), can I get anything back?

    - by duka34
    The worst possible situation... Despite my vigilence doing backups, and trying to keep my PC secure, one of my VMs disk seems to be wiped out. Using the VHD tool from R1Soft (HyperV VHD Explorer), when I attach the VHD, it says no volumes found so it looks like something wiped out the VHD (which it still its original size). It seems that something has sneaked through whatever security I have/had and has wreaked havoc. Can I recover anything from this?

  • Getting PAM/user info into php - something like Net_Finger instead of a db?

    - by digitaltoast
    I've got a very small user group who just need to login, upload, check and then move specific files to a different area when ready. Right now, I use the nginx PAM auth module to log them in against their unix accounts. As their login is their home directory, I've already got the info to send the uploads to the right area - one line of php and no database needed. But I'm maintaining a separate DB just so PHP can welcome them, grab their email and send them an email when processed. Yes, sure I could use nosql or sqlite instead so as to not need a whole mysql install. But it occurred to me that as I've got all these blank user fields for phone numbers I could populate with any data, that I could use something like php's Net_Finger. Which failed for me with: sudo pear install Net_Finger Starting to download Net_Finger-1.0.1.tgz (1,618 bytes) ....done: 1,618 bytes could not extract the package.xml file from "/build/buildd/php5-5.5.9+dfsg/pear-build-download/Net_Finger-1.0.1.tgz" Download of "pear/Net_Finger" succeeded, but it is not a valid package archive Error: cannot download "pear/Net_Finger" At which point I thought I'd stop, and take a ServerFault reality check - is this a really bad/dangerous/stupid idea just to stop me having to maintain details in two places rather than one? It there a better way? Googling shows that it's not an oft-asked thing, so perhaps with good reason?

  • Setup wiped Polycom phone without SIP server

    - by Justin
    I'm troubleshooting a Polycom SoundPoint IP 550. I have wiped the hard disk of the phone (via a menu option) and now it's stuck in a reboot cycle. Apparently the only way to setup the firmware of the phone is to use a boot server. Does anyone know another way to setup the phone/firmware?

  • How do I preserve ownership permissions when copying to an external volume?

    - by Yitzchak
    When I upgrade or reinstall linux I backup my home folder by running sudo cp -pr /home/users/yitzchak /media/externalHDD/backups. When I do this I get errors saying that permissions could not be preserved and when I copy the folder back onto my local disk I see that ownership has been changed to root and I have to chown all of them back, which has to be done manually piecemeal because not all files have the same group. Is there any way around that?

  • SQL Server on VMWare - is transaction log corruption possible?

    - by demp
    Scenario: SQL Server 2005 or 2008, Windows 2008 OS. Running in a VM hosted on VMWare ESX server. Is there any known issue with VMWare when it caches pass-through write request and it never reaches the disk, while SQL Server "thinks" that write actually happened? This may lead to transaction log corruption in case of power failure or VM reboot. Just overheard the conversation but couldn't find it in relation to ESX.

  • What is the reason partitioning is usually a step in installing multiple OS's?

    - by P.S.
    What is the reason partitioning is usually a step in installing multiple (2) operating systems on the same computer? Does an operating system have to have it's own partition to run or can it run in the same partition as another operating system? (i.e. -can two of the same flavor run in the same partition but if you have one Linux and one windows it needs to be partitioned?) Is it necessary to make disk partitions to run multiple operating systems?

  • Constant crashes in windows 7 64bit when playing games

    - by yx.
    I've tried everything I can possibly think of in trying to fix this problem and I'm totally out of ideas, so any help would be appreciated: The problem: whenever I fire up a game, it works for a short while with no problems and then it would crash. Either its a hard crash, forcing me to reboot, or windows would report that the display driver has stopped working and recovered. Here is a list of things I've already tried: Drivers - tried the latest drivers (catalyst 9.12) as well as the stock drivers that came with the video card. Also have the latest BIOS/chipset Memtest - Ran Memtest86+ overnight, had no problems, the windows diagnostic tool also does not find any problems. Overheating - Video card/cpu temperatures are well below peak (42 and 31 Celsius receptively) PSU Voltage - CPUID shows that the voltage levels are all above what they should be. The PSU itself is only roughly 16 months old and is a good model. HDD - No errors when checked GPU - Brand new (replaced previous card since I thought it was the problem, apparently not) Overclocking - Everything is at stock levels, memory voltage is set to manufacturer's standard Specs: Motherboard: ASUS P5Q Pro CPU: Core 2 Duo E8400 3.0 ghz OS: Windows 7 home premium 64 bit Memory: Mushkin Enhanced 4GB DDR2 GPU: Sapphire HD 5850 1GB PSU: SeaSonic M12 600W ATX12V DirectX: DX11 Event Viewer after a crash always has these logged: A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 1 The details view of this entry contains further information. A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 0 The details view of this entry contains further information. A previous card that I had (4850x2) also had these errors, so I changed video cards, but the same thing is happening.

  • AWS instance went down for restart, came back up and has been "Waiting for network configuration... " for 12 hours

    - by kavisiegel
    What happened was about a month ago, I created a new instance, re-configured everything, and mounted the old instances drive to the new one. I then detached the old drive from the instance, but it was still mounted, so it errored out. Now, come the outage last month, and when the instance boots back up - the drive isn't there, because in the downtime, it dismounted. It hangs because the fstab is looking for it. I get word that the server's not up today, I check the logs, re-attach the drive and restart. Now I'm getting "Waiting for network configuration..." and it doesn't seem to be doing anything. Some googling told me that I'm going to need to start from zero again, which I don't think is right. I created a new instance, which booted no problem, then I stopped it and swapped the two old drives into the new instance. Still the same error. Using the fresh AMI, it worked. I figure it's just a misconfigured Amazon file. I can attach the drive to a functioning instance on the same AMI and copy some files over, then try again - but I don't know where to even start or what files to check.

  • Accountability in a cloud infrastructure (Amazon, etc)

    - by WinkyWolly
    I was curious how companies such as Amazon would handle some sort of investigation that needed to look into data potentially stored on one of their on-demand nodes. What typically happens to data in an environment like this after the VM is destroyed (literally what happens on the disk / FS)? Would it actually be possible to recover data from a destroyed node? Just a curiosity :)

  • Cron job checking for changes in Git repository

    - by HNygard
    We have just moved our server configs to a Git repository. Therefore there should not be any changes in any of the repository folders. I was thinking about how I could set up a cron job to check for any uncommited changes. How could a cron job be set up to check for changes in a Git repository? Greping the output of the git status command might just do it. Grep and cron jobs are not my strong side. Here are some sample outputs from git status: Standing the folder containing the git repository (e.g. /path/gitrepo/) with changed files: $ git status # On branch master # Changes not staged for commit: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: apache2/sites-enabled/000-default # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # apache2/conf.d/test no changes added to commit (use "git add" and/or "git commit -a") Standing in the folder when there is no changes: $ git status # On branch master nothing to commit (working directory clean) Update: Synced up with origin is not important. There should be no local changes. Local files that must be in place go into the .gitignore file. In addition to the server configs there are also git repos for content (static web sites, web apps, wordpress, etc). None of the repositories should have local changes. We might use Puppet in the long run since its being used for development of one of the web apps.

  • How big are most production databases?

    - by TheLQ
    Seeing some posts that say 10 million rows in a table is nothing made me wonder: Just how big are most production databases? I'm not talking about physical disk size of the database (saying 60 GB tells me nothing), I'm wondering how many rows. Personally the largest DB I've ever worked with was a test DB of a production system with 10 million rows. But I've seen people brag about DB's in the billions of rows.

  • exchange server 2010 with multiple domains

    - by air
    i have one exchange server 2010, which is working fine with one domain. my exchange is working as follows pop3 collector collect emails from one master catchall account and then deliver to exchange server, this working perfect. now what i want to add another domain to same exchange, i have added new domain as trusted domain & email policy and this new domain email account works fine with internal emails. now what i have done, i again forward new email account to same catchall account. but if i send email from any other external email address email is bounce, i can see email receive by pop3 collector but bounce by exchange server. to make you more clear let me explain logic on which i am working. i have 2 domains 1. domain1.com ([email protected]) 2. domain2.com ([email protected] -->[email protected]) now on my machine with exchange server i have pop3 collector which collect all emails from [email protected] and forward to exchange 2010 server. all emails to domain1.com is working perfect but when i send email to [email protected] this email redirect to [email protected] perfectly but when exchanger server receive this email, it bounce. i have also study the url link text and follow the whole process but no success. i also check that my DNS/MX is working fine as the bounce message is going from my exchange server. EDIT the only problem is with accepted domain, as email come to exchange server then bounce back. i just try this today i create one user called test, then i goto his properties -- email there was only one email account [email protected] i try to send email to [email protected] from internet (email bounce) then again i go to test user properties -- email and Add one email [email protected] again u try to send email to t*[email protected]* from internet (email received) i think the only problem is with accepted domain but in hub transport , it shows accepted is there any way to check does domain is properly accepted or not in exchange 2010 server. Thanks

  • Can't log into Windows XP

    - by lamcro
    Immediately after choosing an account, and starting to log in, it shows the logging out message and goes back to the account selection display. This even happened in safe mode with the administrator's account. So I can't log in. I'll be using a Linux Live CD to extract the laptop's data. Could this be a virus or a hard disk problem? And what should I do?

  • iSCSI NAS supporting VMware Esxi 5.1 servers in a software development environment

    - by BigTFromAZ
    I would like to build (or purchase) the smallest, quietest most energy efficient servers that I can for a low demand environment. These would only have a small disk for guest swap files, a CPU (XEON preferred), 32 Gb of memory and minimal graphics. The virtual machines need to be up but demand will be quite low. Any thought on case, format processors, fans, motherboard, et al? Small, quiet and lots of RAM are the operative words here.

  • XXClone as a tool for migrating Windows XP Home from PATA to SATA HD

    - by raw_noob
    Has anybody had any experience using XXClone as a tool for cloning an existing installation of Windows in order to move it from an old PATA drive to a new, larger SATA without having to reinstall everything? Did you have any problems? Or can you recommend an alternative (free) software tool that you know - preferably from repeated experience - is reliable? I'm looking to move Windows XP Home SP3 to a new disk: same file system, same partition size. Thanks for looking.

  • 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?
