• zeroing a disk with dd vs Disk Utility

  - by jdizzle

  I'm attempting to zero a disk on my Mac OS X machine. I'm going for complete zeros and unformatted, so I think of dd. Unfortunately the maximum throughput I've managed to get out of dd is 7MB/s. Just for grins I tried disk utility and it has a throughput of 19MB/s. What gives? I've tried changing the bs option on dd to all sorts of values, but it still hovers around 7MB/s. Why is disk utility so much faster?

• Windows installation repair option not showing up

  - by Carl

  I'm trying to repair an existing Windows XP installation. Following the instructions from http://www.microsoft.com/windowsxp/using/helpandsupport/learnmore/tips/doug92.mspx this should work: When the Press any key to boot from CD message is displayed on your screen, press a key to start your computer from the Windows XP CD. Press ENTER when you see the message To setup Windows XP now, and then press ENTER displayed on the Welcome to Setup screen. Do not choose the option to press R to use the Recovery Console. In the Windows XP Licensing Agreement, press F8 to agree to the license agreement. Make sure that your current installation of Windows XP is selected in the box, and then press R to repair Windows XP. Follow the instructions on the screen to complete Setup. On step 5 pressing R does nothing and there is nothing on the screen saying it would. When I just select to install I get a message that a previous installation is there and proceeding will destroy it and installed applications, I can optionally select a directory other than c:\windows, and I can optionally format before continuing. I had tried to go from SP2-SP3. It failed, and then I couldn't get to Safe Mode. I put the SP1 disk back in to do a repair, and I don't see that option. (I don't have an SP2 boot/install disk, I just have the non-boot upgrade package.) UPDATE: Upon loading the Recovery Console, I get a message saying The system registry does not appear to have an active ControlSet key. The system registry may be damaged. You can try restarting it with the Last Known Good configuration or you can try repairing the installation of Windows using the setup program's repair and recovery options. I then did bootcfg /scan - "successful" ... Total installs: 1 ... [1] c:\windows - with the c:\windows command prompt below it. bootcfg /list gives [1] Windows XP Pro; OS Load Options /noexecute=optin /fastdetect; OS Location: c:\windows I followed the instructions at http://michaelstevenstech.com/XPrepairinstall.htm - "Warning 2" link copy E:\i386\ntldr C:\ copy E:\i386\ntdetect.com C:\ attrib -h -r -s C:\boot.ini del C:\boot.ini BootCfg /Rebuild I added /fastdetect when it asked for options. I re-ran Windows setup - no change - no repair option. UPDATE: I followed the procedure at http://support.microsoft.com/default.aspx?scid=kb;en-us;307545 I rebooted. I now get a quick message on bootup to select the boot - 1: [blank] ; Windows XP Professional ; Windows Recover Console. The "1: " is new. The rest is the way it was when all was okay. Selecting 1: and the next one gives the same result - I get to a login icon, and then it asks for a password, with the blinking cursor, but I can't type anything. I reboot with the Windows CD. Now I see a repair option for installation "1: " I selected R on that, and it did "Setup is copying files..." and rebooted when it was done. Then it booted, and I got a window saying "Setup will complete in approximately 39 minutes." That's where I am now. I wasn't expecting this last part - I did a repair several months ago and I don't recall that. UPDATE: Booted up. Asked if I wanted to register Windows online. All my icons are there, and the old desktop documents. Good. All the applications I tried from the Start Menu work (tested a few), except Corel Photopaint - I get registry entry not found errors. Windows ran for a while, then froze. The mouse and keyboard don't work. Pressing the power button got Windows to shut down. I probably need to put SP2 on it, and then all the updates for my laptop for XP Pro SP2 (drivers), there's a bunch. The mouse and keyboard quit working again. That wasn't a problem when I first set up this laptop. I've ran 4 times now. Two mouse/keyboards hangs by pressing Ctrl-C (to copy text from a notepad document), and two by selecting Start-Run (wasn't able to type anything in the box).

• Install PHP on RedHat

  - by John R

  I just ran yum install php in the command prompt. Everything went fine ('complete!') as per the dialogue. I then uploaded a file that does not use short tags and is named with the proper extension (i.e., the name is test.php). <?php print "hello world"; ?> When I navigate my browser to test.php it just prints each of the characters shown above; i.e., PHP is not interpreting it. What might be the problem? Also, if there is a configuration file that needs to be updated, please tell me what directory path I am likely to find that file. Edit: Apache2 & Redhat

• How to subscribe to a youtube feed from linux command line?

  - by Tim

  I want to subscribe to a youtube channel and automatically download new videos to my linux machine. I know I could do this e.g. with miro, but I will not watch the videos using Miro, want to choose the quality and would like to run it as a cronjob. It should be able to: know which feed entries are new and not download old entries resume (or at least redownload) failed/incomplete downloads from older sessions Are there any complete solutions for this? If not it would be enough for me (maybe even preferable) to just have a command line rss reader that remembers which entries have already been there and writes the new video urls (e.g. http://www.youtube.com/watch?v=FodYFMaI4vQ&feature=youtube_gdata from http://gdata.youtube.com/feeds/api/users/tedxtalks/uploads) into a file. I could then accomplish the rest using a bash script and youtube-dl. What would be programs usable for this purpose?

• Backup VSS Issues

  - by MJ

  I've got this server, and we've been having VSS issues for quite awhile. We've tried every form of re-registering the VSS drivers we can think of. NTbackup won't run a system state backup vssadmin list writers doesn't list anything. We're getting VSS error 12302 in the event log. Has anyone ran into a situation like this before? We're thinking the next step, if possible, is a complete reinstall of the VSS. Any other ideas?

• What to use as a file server with a web interface and user management on MAMP

  - by Timo

  I want to set up file/photo sharing for a largish group of friends and family. Flickr, Picasa etc. are not optimal solutions because setting up accounts, sharing albums and navigating privacy settings is going to be overwhelming for some of the people. I just want to be able to give people a URL, a username, and password and have it be easy peasy. I want something very simple and easy to use (for the user) like MyTunesRSS. I've looked at a complete "social" solution like Elgg but that feels like using a cadillac to kill a fly. I only need: User management Simple upload / download of files Plug-into-MAMP ease of setup is a bonus Search / metadata / tags / commenting not necessary but also earns bonus points Free / cheap licence What would you recommend?

• There are no drives listed during windows 7 system recovery

  - by Kragen

  I'm trying to use the Windows 7 system recovery disk to repair a boot sector, however I'm finding that when I boot the recovery disk, it doesn't list / mount any of my disk partitions, and so I can't perform the recovery. The partitions are all NTFS formatted, and the drivers used to read the disks all seem to be fairly straightforward Microsoft drivers, so I shouldn't need to load any extra drivers to see my partitions (its a Dell Latitude D530) Diskpart correctly lists the partitions (complete with labels) - it just that when I attempt to switch to that partition it gives me the "This partition does not contain a recognised file system" message. Has anyone got any idea how I can work out why my partitions are not visible?

• MSSQL Auditing Recomendations

  - by Josh Anderson

  As an aspiring DBA, I have recently been asssigned the task of implementing the tracking of all data changes in the database for a peice of software we are developing. After playing with microsoft's change data capture methods, Im looking into some other solutions. We are planing to distribute our product as a hosted solution and unlimited installations would be desired for maximum scalability. Ive looked at IBM's Guardium as well as DB Audit by SoftTree. Im curious if anyone has any solutions they may have used in the past or possibly any suggestions or methods to achieve complete, and of course cost effective, auditing of data changes.

• Simultaneous read/write to RAID array slows server to a crawl

  - by Jeff Leyser

  Fairly beefy NFS/SMB server (32GB RAM, 2 Xeon quad cores) with LSI MegaRAID 8888ELP controlling 12 drives configured into 3 different arrays. 5 2TB drives are grouped into a RAID 6 array. As expected, write performance to the array is slow. However, sustained, simultaneous read/write to the array (wether through NFS or done locally) seems to practically block any other access to anything else on the controller. For example, if I do: cp /home/joe/BigFile /home/joe/BigFileCopy where BigFile is 20G, then even a simple ls /home/jane will take many 10s of seconds to complete. In addition, an ls /backup will also take many tens of seconds, even though /backup is a different array on the same controller. As soon as the cp is done, everything is back to normal. cp /home/joe/BigFile /backup/BigFile does not exhibit this behavior. It's only when doing read/write to the same array.

• Is there a simple way to backup and restore all Microsoft SQL Server database objects related to a p

  - by Nathan Hartley

  I would like to backup, not only the databases that belong to a particular application living on a shared server, but also, those things that get stored outside of the database; the server accounts, jobs, maintenance plans and whatever else I can't think of at the moment. This backup should be complete enough that it's corresponding restore will recreate the entire application on a different SQL server. This seems like a problem others must have dealt with in the past. So before I embark on creating custom Powershell scripts for each application, I have come to ask you... Can you help?

• renaming hard drives (sdc to sdb) on the fly

  - by w00t

  ata2: link is slow to respond, please be patient (ready=0) kernel: [2761026.198796] ata2: soft resetting link kernel: [2761031.226669] ata2.00: disabled kernel: [2761031.226720] ata2: EH complete kernel: [2761031.226753] sd 1:0:0:0: [sdb] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK After receiving the error above, I couldn't access /dev/sdb anymore. Not wanting to restart the server, I rescanned for the device using echo "- - -" > /sys/class/scsi_host/host1/scan and it readded the drive as /dev/sdc. From what I have found, I need to use echo "scsi add-single-device 0 0 3 0" > /proc/scsi/scsi, "3" being the SCSI ID which corresponds to sdb. Everything nice up to the point I execute the command and get -bash: echo: write error: Invalid argument. All the solutions point to using this method, but I am unable to. Any other method available?

• How to install software packages on a shared Red Hat Linux host account without root access or rpm?

  - by jeff

  I have a shared RHEL 4 host account where I do not have root privileges. I would like to install Git and Bash Complete in a way that they can be upgraded easily. To date, I've just been installing from source providing $HOME as a prefix to autoconf. Obviously this isn't ideal as I need to hunt down the files associated with the version I'm upgrading away from and delete them. I've tried using rpm but I just get -bash: rpm: command not found back so it's not available. I also looked into checkinstall but it looks like that requires rpm, dpkg, or Slackware's package manager to be available. Is there anything out there that can be used like a package manager without requiring root access or an existing package manager?

• Can't create a registry key under Eventlog and I am in administrators group

  - by Tony_Henrich

  I am troubleshooting an installer problem where it's giving an error writing to a registry key. So when I use the Registry Editor (regedit) to create the same key under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog, I get a "Cannot create key: Error writing to the registry". Looking at the permissions, administrators have full access and I am a member of that group. I can create entries in other areas in the registry. When I try to take ownership, I see my name already listed. But then I get an error "Unable to set new owner on Eventlog. Insufficient system resources exist to complete the requested service". I tried after a new reboot. I turned off my firewall (Comodo). Why can't I create a new key when I am an admin and permissions indicate I have full control?

• Installing Windows on HP Proliant Servers without SmartStart

  - by Fitzroy

  I have a PXE server for deploying Windows XP and Windows 7 to workstations. The process is as follows: Boot the workstation from the NIC. Workstation sends a DHCP request. DHCP server responds with an IP address and the location of the PXE server. Workstation downloads WinPE image file from PXE server via TFTP Workstation stores WinPE image file in memory and executes it. Once booted into WinPE, I connect to a network share to gain access to either the Windows XP or Windows 7 installation files. A custom script is launched to guide you through the process of formatting and partitioning the hard drive(s) (using DISKPART and FORMAT). Another custom script asks for details such as the hostname to assign to the workstation. The answers provided are used to build an unattended answer file (SIF [Setup Information File] for WinXP and XML for Win7). The Windows setup EXE is launched, passing the unattended answer file to it as a parameter. The Windows XP and Windows 7 installation sources have been customised to include the drivers for our Dell workstations. They also run a number of scripts upon first booting up to install software packages. This process works very well for our workstations and I would now like to use it for building our servers too. The vast majority of our servers are HP Proliant DL360 G6, DL380 G5 and DL380 G6. They’re running Windows Server 2003 (various editions) or 2008 (various editions). To date, we have always built the HP Proliant servers using the SmartStart CD provided. SmartStart does three useful things for us: Setup RAID with HP Array Configuration Utility (ACU). Installs and configures SNMP Installs various HP Tools for Windows (HP Array Configuration Utility, HP Array Diagnostic Utility, HP Proliant Integrated Management Log Viewer, etc) Using SmartStart I have never had to manually download and install Windows drivers for network, sound, video, etc. I'm not sure if this is because SmartStart copies drivers from the CD during setup, or whether Windows just has the drivers natively in its driver CAB. If I abandon the SmartStart CD in favour of my PXE server I would have to do the following: As I wont have access to ACU, I'll configure the RAID (before booting to the PXE server) by pressing F8 (during the boot process) to access Option ROM Configuration for Arrays (ORCA). Installation of SNMP and the HP Tools will have to be installed once the Windows installation is complete using the Proliant Support Pack. Is this method OK? Is there anything that the SmartStart CD does that I'll be unable to do by other means? Are there any disadvantages to not using the SmartStart CD? Many thanks. UPDATE 05/01/12 I’ve been reading through the SmartStart Scripting Toolkit documentation. The scripting toolkit contains command line tools which work within WinPE and can such things as configure BIOS settings, configure an array and setup ILO. I’m personally not too bothered about configuring BIOS settings as I rarely deviate from the defaults (unless the server is to be a Hyper-V host). I’m not too fussed about being able to configure the array from within WinPE, as I’m happy to just press F8 and use Option ROM Configuration for Arrays (ORCA). Although, if it’s easy enough to do, I will explore this further, as it saves time if everything can be configured from within WinPE. One of the nice features all the tools possess is that you can pass input files to them. EG. Configure one server to your requirements, capture its configuration to a file (using the appropriate tool), you can then use the tool on other servers passing the input file with the captured configuration. Array controller drivers appear to be included with the toolkit along with example of how to incorporate them within a WinPE build. I suppose WinPE won’t be able to see logical volumes (I.E 2x physical disks in a RAID 1 configuration) without the array controller drivers? I mentioned in my post that SmartStart normally installs a bunch of Windows HP tools for you. I’ve had a look today, and if you run the SmartStart CD from within Windows all the tools can be installed. Therefore I can do this after the Windows installation is complete. The SmartStart CD appears to contain a lot Windows drivers. I can customise my Windows 2008 source to incorporate these drivers. However, I understand that incorporating an array controller driver is a little different to most drivers. I believe that you have to provide the driver during the very early stages of the Windows setup. I’m working through the Scripting Toolkit documentation to try and work this out...

• windows 7 losing wired ethernet connection

  - by Brandon Grossutti

  i have a win 7 machine with an Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller with latest drivers, the machine is upto date with all latest fixes etc. I have it connecting to a WRT310Nv2 router. Seemingly random, win 7 disconnects from the "Home Network" says its in a "public network", then resets the connection to an illegal 169 address. I have tried static ips, dhcp, all with the same results. This seems to have started shortly after i installed Vuze, so I uninstalled it but the problem persists. I know that the router is sound given that I have an XP machine attached with no issues of connectivity at all. I am at a complete loss and have tried everything, pleasse tell me i'm not the only one.

• How to dump only a certain part of SVN repository?

  - by dehmann

  How to you move a part of an SVN repository into a new repository? To move the contents of a complete SVN repository into a new repository, one has to dump the old repository first: svnadmin dump /path/to/repository > repository-name.dmp and then load it into the new one using svnadmin load. But I'm not sure how to just move a part. Do I still have to dump the whole thing? Do I grep for the part that I want? To just dump myproject, I tried this, but it didn't work: svnadmin dump /path/to/repository/myproject

• Another installation is in progress

  - by Steven

  Why I try to install any program I see "Another installation is in progress. You must complete that installation before continuing this one." error. Googled the web and found that solution would be to delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\InProgress registry key and reboot. That didn't help me unfortunately. When I open "Services" mmc snapin it shows that "Windows Installer" service is "Started", but "Start/Stop/Pause/Restart" buttons are grayed (the interesting thing is that startup type = "Manual", so I don't really know how to explain that I already have 2 instances of msiexec.exe in memory and one instance is consuming 50Mb of memory. Looks like there's a serious issue with my installer service - is there any way to fix it (please do mind - I can't install anything!) Any help would be greatly appreciated.

• Can the Windows 8.1 update be applied without local terminal?

  - by Ben Voigt

  It is possible to access the Windows Store from a remote desktop session and initiate the Windows 8.1 Update from the Windows Store, but the update hangs after the first reboot, likely waiting for the user to accept the license check. This leaves the computer unusable remotely. Is there a way to pre-accept the license terms so that the update can complete autonomously? Perhaps an UNATTEND.XML such as would be used for an unattended clean install? Failing that, is there a way to connect with remote desktop during that phase of the install (it appears to be GUI-mode setup running with the usual Windows kernel and full OS)?

• Referring to mailmerge fields in an if statement

  - by Zian Choy

  Context: Windows 7 Microsoft Office Word 2007 I have a mailmerge field named "On_FB". Current code: { IF { On_FB } = "Y" "You're on Facebook." "You're not on Facebok."} The moment I get out of code-editing view, the code goes haywire. When I flip back to code-editing view, I see that the code has magically turned into: { IF " Y" = "Y" "You're on Facebook." "You're not on Facebok."} Needless to say, this is a complete bust because it will always say that the person is not on Facebook. I tried putting { On_FB } on its own and that works fine. What can I do to make the If statement work? (By the way, all the { and } were inserted via CTRL+F9.)

• ESXi 5.1 on Poweredge 510 freezes after base-esx update

  - by goober

  Background / Problem Just experienced an issue where an ESXi host was upgraded from 5.0 -- 5.1 perfectly fine. Then, I did a scan and remediated a patch (ESXi510-201210401-BG) Looking into the host on via the kvm switch, this appears to complete successfully. However, on reboot, the server hangs at the "Initializing Power Management" phase. I've read from various spots around the internet that this usually clears itself up again upon a cold boot, but given that our servers are in a different building with different access rules, the less I have to physically go there, the better. :) Question Is there anything I can do to avoid an ESXi host hanging at the "initialize power management" phase of boot after remediating the host to apply patches?

• Any ideas for automatic initial/scripted configuration of a NetApp?

  - by maddenca

  The background is to make a solution where we can automate as much as possible the building up of ‘pods’ that include server/network/storage and that will be built at remote sites. In an ideal world would be that we create a single management server which is preconfigured with DHCP/TFTP/or whatever. This management server is racked with a CISCO UCS, FAS31x0, etc. at a build site and is then transported to the final customer site where on power it almost configures itself, or at least bootstraps itself far enough that a remote skilled 'expert' can complete the setup of the pod. Ideas (doesn't have to resemble 100% of the above) would be helpful.
