  • HP DL160 vs DL360 for virtualization

    - by Chris
    Hi, We're planning to consolidate our infrastructure (a dozen servers). We'll buy two or three identical new servers who will be setup as a XenServer pool. Load balancing and HA tools will monitor the pool and vMotion VMs in case of failure/overload. I know that the DL100 series of HP servers is cheaper than the DL300 serie (in every sense of the word). As we don't need local storage (we have a SAN) and can live with a temporary down server (provided that Xen Server HA tools work as advertized), what are the downsides going with the DL100 serie ? Thanks, Chris

  • Understanding Windows 8 Recovery options

    - by stuffe
    Background: I am preparing a PC that I am sending to a relative abroad, who has little or no internet access, and next to no sensible options for getting IT support should anything go wrong. As such I am trying to provide a full set of recovery options such that they are able to reinstall the OS with minimum fuss or assistance if required. The PC is a brand new Acer laptop that came with Windows 7 pre-installed (and an associated recovery partition) and a free upgrade to Windows 8. I have installed Windows 8 from scratch performing a format and clean install from media I burned from the official download. The existing Windows 7 recovery partition is still there, and I can still boot from it. I have created recovery DVDs of that in case it is ever lost. Here are my recovery options so far. I can perform a factory reset of Win 7 via the recovery partition I can perform a factory reset of Win 7 via burned recovery DVDs I can re-install Windows 8 cleanly from a DVD All of these are useful, but not what I want, because the first 2 methods use Win 7, and still fill the machine with crapware, and the latter doesn't provide for any post-install customisation and software installation. So, I am looking to see what other options are available to perform a Windows 8 recovery that will be more than a simple install. I am aware that Win8 comes with some useful refresh tools: Refresh your PC - Re-install Win 8 over the top of your existing installation, recovering from any Windows corruption etc. I can run this from my current install, although it says some files are missing that will be provided by me install or recovery media, which seems to be code for stick your install DVD in, and it starts after I do that - unfortunately for this particular laptop you need to specify a particular WIFI driver or the install bombs out part way through with IRQL errors, and this refresh method skips the part where you can load a driver, so it's no use to me. I think I can fix this by creating a custom recovery image using the recimg.exe command but it takes hours to complete so I haven't tried it yet. Reset your PC - Perform a full install and lose all your files. Again it needs my Install media inserting before it will do anything, but then it provides an error (will include later when I recreate it...) Now, these recovery options look useful (in principal, although both are fail for me) but they rely on having a working system to access the tools, which leads me to the last option, of making a Recovery USB drive. I have made a recovery drive, and it should perform loads of useful things, including copying my WIN7 recovery partition to the drive, providing the above refresh and reset options, providing other troubleshooting options and also the ability to restore from a custom image, only none of them seem to work for me. Creating the Recovery Drive - the option to include my recovery partition is greyed out. The partition exists and works fine, why will it not copy it? Refresh - I imagine this would have the same issues as I described before, but this is moot because when I try it says that the "drive where Windows is installed is locked, please unlock the drive and try again" with no info on what that means and how to do it. Restore - Again, probably pointless as I can just use the DVD, but it also errors: "unable to reset your PC. A required drive partition is missing" System Restore - should let me roll back a bad driver etc as per normal in Windows, only it simply says "To use system restore you must specify which windows installation to restore. Restart this computer, select an operating system, and select system restore" ?!?! System Image Recovery - this seems to be offering to restore from a Windows system image, but this is deprecated in Windows 8, although you can still make one if you use the Windows 7 Backup tools, however the resultant file is too large to put on the USB stick as it's FAT formatted, and would be a massive stack of DVDs anyway. So useless. It would be nice it it would work with the custom recovery image you can use with the refresh command, but there seems no option to do this. Automatic Repair - some diagnostics, which seem useless as it happily tells me it can't fix my problem, even though I have none. Command Prompt - yay, this works! What on earth do I want to use it for... Had any of the above worked, it might be useful, but as any form of install still requires you to have the DVD, and any form of custom recovery image also requires you to have either a massive stack of DVDs or an NTFS formatted backup device in addition to the recovery drive, it sort of ruins the point. It doesn't seem rocket science. I want to create a bootable USB drive that I can refresh Windows over an existing install with, perform a clean reinstall to a bare system, or recovery a customised image with existing apps installed. If anyone can point me in a direction that allows me to make a single recovery drive do these all these things, I would appreciate it. I have a 32Gb USB3 thumb drive that I bought for this very purpose, but it's seems to be fighting to let me do anything useful. At this rate I will be making a DriveImageXML recovery stick and dumping the OS with that, which I know works, but isn't so elegant as using the proper tools..

  • Uninstalled programs cleaner

    - by ldigas
    Generally, I'm looking for a recommendation for an uninstalled programs cleaner ? What is it ? You have a program, you uninstall it, and it leaves a bunch of crap on your machine, starting from registry entries, to shortcuts that lead nowhere, up to a bunch of no more used files in Program Files and so ... Registry cleaners usually do some of this stuff, but 'twas wondering, what are good tools that have it all in one package ? I know such tools exist, 'cause in the past I've met with a few. Only I didn't need them then ;)

  • Alignment requirements: converting basic disk to dynamic disk in order to set up software RAID?

    - by 0xC0000022L
    On Windows 7 x64 Professional I am struggling to convert a basic disk to a dynamic one. Under Disk Management in the MMC the conversion is supposed to be initiated automatically, but it doesn't. My guess: because of using third-party partitioning tools there isn't enough space in front and after the partitions (system-reserved/boot + system volume) to store the required meta-data. When demoting a dynamic disk to a basic disk manually, I noticed that some space seems to be required before and after the partitions. What are the exact alignment requirements that allow the on-board tools in Windows to do the conversion?

  • Ubuntu Natty: 32-bit userland, 64-bit kernel?

    - by dsimcha
    I'm trying to manually install a 64-bit kernel for 32-bit Ubuntu. I have my reasons for doing so, but they're too complicated to explain here. Prior to Natty, this worked fine.

  • Recommended apps for securing/protecting a new desktop machine install?

    - by Eddie Parker
    I'm hoping to harness the collective tips of superuser to gather recommended apps/configurations to keep a new desktop clean, virus free, and hopefully lower software rot. I ask because I've recently come across tools like dropbox, deepfreeze, returnil, etc, and I'm curious what other ones are out there to protect a new box. I personally am interested in Windows, but feel free to comment on whatever OS you'd like, freeware or otherwise. Ideally specify the OS in your answer(s). One answer per program please. Then, rather than duplicate posts, vote for the program if it is already listed. UPDATE: It's been noted that there are other questions similar to this one [1], so I'd ask that these answers focus on security and protection. [1] Related questions: http://superuser.com/questions/1241/what-are-some-must-have-windows-programs http://superuser.com/questions/1191/what-are-some-must-have-mac-os-x-programs http://superuser.com/questions/1430/must-have-linux-software http://superuser.com/questions/3855/must-have-networking-security-tools

  • Server Core remote management from Windows 7 machine

    - by Robert Koritnik
    I've installed Remote Server Administration Tools for Windows 7 because I would like to administer my Windows Server 2008 R2 Server Core machine. The problem that I'm getting when I try to run Server Manager is: Connecting to remote server failed with the following error message: Access is denied. For more information, see the about_Remote_Troubleshooting Help topic. This is what I've done so far: I'm running WinRM service on both machines (Server and Window 7) I've added my server to trusted hosts on my Windows 7 machine: winrm set winrm/config/client @{TrustedHosts="WINSRV2"} I've added registry entry on Windows 7 machine: reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f I've enabled Remote Management inbound rule on server firewall using CoreConfigurator 2.0 both machines are in the same subnet and when I search for network machines on Windows 7 I see my server. Question What else should I do to make it work? I would like to run several different remote management tools against my server machine.

  • What are good replacements for Microsoft Visio 2003?

    - by James
    I have been using Visio 2003 on Windows XP for generation of UML diagrams. I have encountered following problems so far: There is no way to generate/print the documentation written for class attributes/methods. No automatic code generation is supported I have already generated lot of diagrams and i discovered above problems at much later stage. Now i would like to overcome above by choosing another tool which is compatible with Visio file(.vsd) which saves time or redrawing all diagrams and also provides above features. Could you kindly suggest an alternative (visio compatible) tool ? (I have looked at a similar SU-question, but it does not suggest tools which provide solution to above problems. I am open to free as well as licensed tools, with priority to free :) ) Thanks, James

  • Inter-VLAN Malicious Code Scanning

    - by Jackthedog
    I am trying to find an inbuilt solution on a Cisco Catayst 3750X Switch to scan all traffic routed from one VLAN to another for malicious code. The situation is that we currently have a development environment which is currently being redesigned to upgrade the network infrastructure to use the 3750X switches to manage server and workstation connectivity as well as inter-VLAN routing. We also have another system that is responsible for taking the builds created on the development environment and imaging various HDDs. Because these are two separate systems, we have a requirement in the workplace to anti-virus scan any data transferred between these systems. This is done by copying the data from the originating system to external USB HDD, scanning in a standalone workstation and then copying the data on to the receiving system. As you can imagine this is extremely tedious and impractical most of the time... (I don't make the rules). Anyway, with this redesign going on, we would like to join the imaging system to the network infrastructure of the development system, keeping separation by the use of VLANs and restricting traffic by using ACLs. As we still have the requirement to scan all traffic I would like to configure some sort of malicious code scanning when ever traffic is routed between these VLANs. I am aware I could install a separate in-line IPS/IDS device, however both systems will be using multiple ports on the switch (obviously), and we won't be able to put a device on each port. I would would prefer not to add additional hardware if the 3750x switch is capable of doing the job. Is anyone aware of any Cisco solution that I could use here, that ideally can be incorporated into the 3750x switch? Thanks in advance.

  • Free desktop recording / screencasting on windows

    - by Mercer Traieste
    I'm a newbie in desktop recording and screencasting. I didn't find a suitable free application to do all the things I want it to do, but I did enjoy using jing. I would expect such an application to have these features: choose the whole desktop, a region, a window to record zoom in an area, and camera move save the recorded movie to a compressed format have basic editing tools have the mouse highlighting feature (either a sonar blip or something similar) highlight window/field on the screen, any trick will do display pressed keys/key combinations (like iphone does) So the question is: Which free desktop recording/screencasting software would you recommend on windows? It doesn't have to have all those features, just tell me your favorable experiences. Please suggest tools that would do mouse/keys/areas highlight tricks. I'm open to commercial software too, but I would prefer a free one. Thank you!

  • Recommendations for screen-capture tool that retains menus and mouse pointer

    - by Chris Farmer
    There are several screen capture tool questions already on this site, but I think I have a slight tweak to the usual. I'd like a handy screen capture utility that can: Run in Windows 7 Capture a sub-region of the screen Show the current state of the mouse cursor and any active menus I'd like to use it for writing docs that refer to specific application menu items. I like the built-in snipping tool in Windows 7, but the act of using it dismisses my menus, and it doesn't get the mouse cursor either. Do any such tools exist? EDIT: Ahh, I wasn't familiar with the "delayed capture" options of these tools, but they all seem to fit the bill. Thanks!

  • Squid proxy in cent os often disconnected with error : tunnelConnectTimeout(): tunnelState->servers is NULL

    - by Ela
    I am having very often internet disconnection problem with Squid proxy service. My server config; OS: CentOS release 6.3 (Final) model name : Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz cpu MHz : 1600.000 My Local systems IP range:192.168.2.x Server IP: 192.168.2.11 Also this server is configured with lamp for development,Samba SMB file service manager and No svn currently. So i see maximum possibility is this squid proxy since this is where it stops to connect and am sure when i restart the server net started working so something wrong with this squid service only. And this server is connected with local 14 other windows machines and basically serves as a central development node. I am able to resolve it by restarting the server fully some time or sometimes by restarting the squid proxy which is totally killing our development. I have attached my cache log file here for the error info. Cache log file Sample error log: 2013/07/01 13:25:38| tunnelConnectTimeout(): tunnelState->servers is NULL 2013/07/01 13:25:41| tunnelConnectTimeout(): tunnelState->servers is NULL 2013/07/01 13:25:41| tunnelConnectTimeout(): tunnelState->servers is NULL 2013/07/01 13:25:50| clientProcessRequest: Invalid Request 2013/07/01 13:26:05| tunnelConnectTimeout(): tunnelState->servers is NULL Some help can make our lives easier, Thanks in advance.

  • Which dbghelp.dll do I use for debugging?

    - by Coldblackice
    I'm trying to configure symbols in Process Explorer. I have the Windows SDK installed (and thus, Debugging Tools). However, there are two versions of dbghelp.dll -- x86 and x64. Which one do I use? Other sources on the net say to just point to the dbghelp.dll that's in the base directory of the Debugging Tools. But there's no such dbghelp.dll -- they're in their respect 32 and 64 bit folders (i.e., C:\Program Files (x86)\Windows Kits\8.0\Debuggers\x64). I'm using a Windows 7 x64 operating system, so does that mean I should load the x64 .dll? Or is it a matter of what I'm debugging? If it is a matter of what I'm debugging, does that mean that I have to switch this .dll depending what process I want to get symbol information on in Process Explorer?

  • Lost HDD partition to clean command, testdisk unresponsive

    - by Sujay Anjankar
    I accidentally cleaned my external HDD by the clean command in Diskpart and got a full sized heart attack after that. I did some research and I have tried a number of tools already. To name a few: Testdisk Recuva Partition Find and mount Eassos Recovery I have even tried some other dumb sounding tools, but none of them could find the lost partition. They just show "no partition found". Testdisk shows Partition sector doesn't have the endmark 0xAA55. The file recovery softwares list the files, but none of them seem to be able to restore the lost partition. I need to recover the disk as it was. Any help would be much appreciated!

  • Hardware asset management systems

    - by Dave
    I need to track a bunch of specialized testing tools, They are hardware devices used for testing other equipement. Each device has a serial number and is sent out for use in testing. Occasionally they break and have to be sent to the manufacture for repair. I'm looking for an open source application (preferably a webapp) to help manage them. Right now we're using Excel and it's not scaling as we get more tools. They aren't computers so all the standard IT asset management systems don't really fit the bill. I found h-harmony, but that project seems dead?

  • Vista: Improving troubleshoot approach skills

    - by Chau
    I'm not a Windows SuperUser, but neither just the regular user. I don't mind browsing the Registry, using Process Explorer, reading the Event logs, (un)installing new drivers and so on, but all this only makes me solve some problems. I tend though to run into problems where these tools aren't enough. Which tools should I learn about to improve my troubleshooting skills in Windows? Currently I'm using Windows Vista x64 (not moved to 7 yet), facing audio/video stuttering problems and I think this is a good place to improve my troubleshooting skills.

  • IE8 Compatibility View issues

    - by 08Hawkeye
    I have the IE7 emulater tag in a jsp layout. But when I bring up the page, it defaults to the IE8 view until the user clicks the Compatibility View button. I don't want the user to have to click the button to launch compatibility mode. Is there a way to force IE7 Emulation on pageLoad? I'd even like to disable the button (or any potential to toggle between IE8 standard mode/IE7 view). Thanks! //sw Update: Now the button seems to have disappeared entirely, but still defaults to IE8 standards. Where did it go?! The toolbar context menu has it as selected, but the tools dropdown menu has it grayed out. For my purposes, it is unacceptable for the user to have to use the developer tools or even click the button to trigger emulation, but I don't know why the button disappeared anyway...
