• How to get more information from the system crash

  - by viraptor

  I'd like to debug an issue I'm having with a linux (debian stable) server, but I'm running out of ideas of how to confirm any diagnosis. Some background: The servers are running DL160 class with hardware raid between two disks. They're running a lot of services, mostly utilising network interface and CPU. There are 8 cpus and 7 "main" most cpu-hungry processes are bound to one core each via cpu affinity. Other random background scripts are not forced anywhere. The filesystem is writing ~1.5k blocks/s the whole time (goes up above 2k/s in peak times). Normal CPU usage for those servers is ~60% on 7 cores and some minimal usage on the last (whatever's running on shells usually). What actually happens is that the "main" services start using 100% CPU at some point, mainly stuck in kernel time. After a couple of seconds, LA goes over 400 and we lose any way to connect to the box (KVM is on it's way, but not there yet). Sometimes we see a kernel reporting hung task (but not always): [118951.272884] INFO: task zsh:15911 blocked for more than 120 seconds. [118951.272955] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [118951.273037] zsh D 0000000000000000 0 15911 1 [118951.273093] ffff8101898c3c48 0000000000000046 0000000000000000 ffffffffa0155e0a [118951.273183] ffff8101a753a080 ffff81021f1c5570 ffff8101a753a308 000000051f0fd740 [118951.273274] 0000000000000246 0000000000000000 00000000ffffffbd 0000000000000001 [118951.273335] Call Trace: [118951.273424] [<ffffffffa0155e0a>] :ext3:__ext3_journal_dirty_metadata+0x1e/0x46 [118951.273510] [<ffffffff804294f6>] schedule_timeout+0x1e/0xad [118951.273563] [<ffffffff8027577c>] __pagevec_free+0x21/0x2e [118951.273613] [<ffffffff80428b0b>] wait_for_common+0xcf/0x13a [118951.273692] [<ffffffff8022c168>] default_wake_function+0x0/0xe .... This would point at raid / disk failure, however sometimes the tasks are hung on kernel's gettsc which would indicate some general weird hardware behaviour. It's also running mysql (almost read-only, 99% cache hit), which seems to spawn a lot more threads during the system problems. During the day it does ~200kq/s (selects) and ~10q/s (writes). The host is never running out of memory or swapping, no oom reports are spotted. We've got many boxes with similar/same hardware and they all seem to behave that way, but I'm not sure which part fails, so it's probably not a good idea to just grab something more powerful and hope the problem goes away. Applications themselves don't really report anything wrong when they're running. I can run anything safely on the same hardware in an isolated environment. What can I do to narrow down the problem? Where else should I look for explanation?

• how does openvpn decide which interface to get IP addrs from

  - by bkrupa

  Using ubuntu 10.04 on both ends. We have a client and server machine on the SAME network attempting to make a vpn connection. We use the config files from here and made minimal changes. The server and client start and seem to connect without any trouble.

• Need advice on which PCI SATA Controller Card to Purchase

  - by Matt1776

  I have a major issue with the build of a machine I am trying to get up and running. My goal is to create a file server that will service the needs of my software development, personal media storage and streaming/media server needs, as well as provide a strong platform for backing up all this data in a routine, cron-job oriented German efficiency sort of way. The issue is a simple one - all my drives are SATA drives and my motherboard controller only contains 4 ports. Solving the issue has proven to be an unmitigated nightmare. I would like advice on the purchase of the following: 4 Port internal SATA / 2 Port external eSATA PCI SATA Controller Card that has the following features and/or advantages: It must function. If I plug it in and attach drives, I expect my system to still make it to the Operating System login screen. It must function on CentOS, and I mean it must function WELL and with MINIMAL hassle. If hassle is unavoidable, there shall be CLEAR CUT and EASY TO FOLLOW instructions on how to install drivers and other supporting software. I do not need nor want fakeRAID - I will be setting up any RAID configurations from within the operating system. Now, if I am able to find such a mythical device, I would be eternally grateful to whomever would be able to point me in the right direction, a direction which I assume will be paved with yellow bricks. I am prepared to pay a considerable sum of money (as SATA controller cards go) and so paying anywhere between 60 to 120 dollars will not be an issue whatsoever. Does such a magical device exist? The following link shows an "example" of the type of thing I am looking for, however, I have no way of verifying that once I plug this baby in that my system will still continue to function once I've attached the drives, or that once I've made it to the OS, I will be able to install whatever drivers or software programs I need to make it work with relative ease. It doesn't have to be dog-shit simple, but it cannot involve kernels or brain surgery. http://www.amazon.com/gp/product/B00552PLN4/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B003GSGMPU&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1HJG60XTZFJ48Z173HKY So does anyone have a suggestion regarding the subject I am asking about? PCI SATA Controller Cards? It would help if you've had experience with the component before - that is after all why I am asking here - for those who have had experience that I do not have. Bear in mind that this is for a home setup and that I do not have a company credit card. I have a budget with a 'relative' upper limit of about $150.00.

• Dangers of Running Computers w/o Air Conditioning

  - by Daniel Bingham

  I recently moved in to an apartment with out air conditioning. This is fine most of the time as I am in upstate New York. It only ever gets above the high 70s during the hottest of the summer months. And when it does, I'm stubborn enough that I'll just deal with wearing minimal clothing around the house. However, I'm worried about my computers. I'm a software developer and gamer, so many of my machines are very high powered. And at least one of them is a server that must be left on 24/7 (not just a game server - also serves multiple websites). I've never before had to worry about the heat too much, as I always lived in buildings with central air. The in building temperature rarely got much above 70 F. All of the machines I built had good enough air cooling that I never saw a problem. Now the temperature in building is pushing 100F and I'm worried that the machines will not be able to keep themselves cool enough by simply blowing already hot air over themselves. The hottest of them I've turned off. However, the server I cannot. It's an old Dell (not custom build) that runs on a Pentium 4 (2.2GHz). It only has a single hard drive, integrated video. And it'd not running any processor intensive servers. Just basic LAMP. It used to run a MUD server, but that's off for now. So it should be idling most of the time. I haven't been able to find any sort of built in temperature sensors in the hardware... at least not any that the programs I've found in the Debian repository can read. And it's an inherited machine to which I do not have the full specs, so I don't know the tolerances anyway. How worried should I be about it melting down on me? How worried should I be about the hard drive melting or becoming corrupted? To generalize the question for other people, what are the safe temperature tolerances for most machines. How widely does it vary, and how does one go about determining when their machine is running too hot and needs to be shut down?

• Assign fixed IP address via DHCP by DNS lookup

  - by Janoszen

  Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

• How to encrypt dual boot windows 7 and xp (bitlocker, truecrypt combo?) on sdd (recommended?)

  - by therobyouknow

  I would like to setup a dual boot Windows 7 and Windows XP laptop/notebook computer where each operation system's partition is fully encrypted. I would like to do this on a SSD - a 128Gb Crucial M4. My research Dual boot of truecrypt encrypted OSs on one drive (not possible - in Truecript 7.x at time of writing) This cannot be done on a standard Truecrypt setup - it will only support encrypting one of the operating systems. I have tried this and also read about it here on superuser.com However, I did see a solution here that uses grub4dos as the initial bootloader to chain to separate truecrypt encrypted OSs, in my case Windows 7 and Windows XP: http://yyzyyz.blogspot.co.uk/2010/06/truecrypt-how-to-encrypt-multiple.html I am not going to consider this solution as it relies upon some custom code for use in the bootloader that is provided by the author. I would prefer a solution that can be fully understood so that I can be sure that there is nothing undesirable occuring (i.e. malware or just simply bugs in the code). I would like to believe such a solution doesn't have those risks but I can't be sure. BitLocker and Truecrypt combination - possible solution? So I am now considering a combination of encryption programs: I now aim to encrypt Windows XP with Truecrypt and Windows 7 with BitLocker. Assuming Truecrypt bootloader can boot into non-Truecrypt OSs (e.g. via hitting Escape to go to another menu), then this solution may be viable. SSDs and Encryption (use fastest possible spinning hard disk instead (?)) I read on various superuser.com posts and elsewhere that current SSDs are not suited to whole drive encryption for various reasons: impact of performance algorithms that give SSDs advantage over spinning harddisks. Algorithms used in compression of data for example. Wear on the SSD, shortening its life Security issues whereby data is repeated, as indicated in some Truecrypt documentation So I am now considering not using SSD. But with the aim to have the fastest drive possible, I am considering using the Western Digital Scorpion black 2.5" 7200rpm harddisk as this appears to be top rated among spinning platter-based harddrives (don't work for Western Digital). Summary So to achieve whole drive encrypted dual boot Windows 7 and Windows XP with minimal performance impact I intend to use a combination of Truecrypt and Bitlocker on a top-rated conventional spinning platter-based harddisk. Questions Will my summary: achieve whole disk encryption of the dual-boot Windows XP, Windows 7? OR an you suggest a simpler solution, including one that only requires only Truecrypt (BitLocker not available on XP). Or another encryption tool, including paid-for? provide the highest performance. Am I correct to avoid using SDD with encryption for the reasons I discovered? Are the concerns about SSDs and encryption still very real (some articles I read go back to 2010) Thanks for your input!

• recommendations for efficient offsite remote backup solution of vm's

  - by senorsmile

  I am looking for recommendations for backing up my current 6 vm's(and soon to grow to up to 20). Currently I am running a two node proxmox cluster(which is a debian base using kvm for virtualization with a custom web front end to administer). I have two nearly identical boxes with amd phenom II x4's and asus motherboards. Each has 4 500 GB sata2 hdd's, 1 for the os and other data for the proxmox install, and 3 using mdadm+drbd+lvm to share the 1.5 TB's of storage between the two machines. I mount lvm images to kvm for all of the virtual machines. I currently have the ability to do live transfer from one machine to the other, typically within seconds(it takes about 2 minutes on the largest vm running win2008 with m$ sql server). I am using proxmox's built-in vzdump utility to take snapshots of the vm's and store those on an external harddrive on the network. I then have jungledisk service (using rackspace) to sync the vzdump folder for remote offsite backup. This is all fine and dandy, but it's not very scalable. For one, the backups themselves can take up to a few hours every night. With jungledisk's block level incremental transfers, the sync only transfers a small portion of the data offsite, but that still takes at least a half an hour. The much better solution would of course be something that allows me to instantly take the difference of two time points (say what was written from 6am to 7am), zip it, then send that difference file to the backup server which would instantly transfer to the remote storage on rackspace. I have looked a little into zfs and it's ability to do send/receive. That coupled with a pipe of the data in bzip or something would seem perfect. However, it seems that implementing a nexenta server with zfs would essentially require at least one or two more dedicated storage servers to serve iSCSI block volumes (via zvol's???) to the proxmox servers. I would prefer to keep the setup as minimal as possible (i.e. NOT having separate storage servers) if at all possible. I have also briefly read about zumastor. It looks like it could also do what I want, but it appears to have halted development in 2008. So, zfs, zumastor or other?

• Hardware for multipurpose home server

  - by Michael Dmitry Azarkevich

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

• Install XP Mode with VirtualBox Using the VMLite Plugin

  - by Mysticgeek

  Would you like to run XP Mode, but prefer Sun’s VirtualBox for virtualization?  Thanks to the free VMLite plugin, you can quickly and easily run XP Mode in or alongside VirtualBox. Yesterday we showed you one method to install XP Mode in VirtualBox, unfortunately in that situation you lose XP’s activation, and it isn’t possible to reactivate it. Today we show you a tried and true method for running XP mode in VirtualBox and integrating it seamlessly with Windows 7. Note: You need to have Windows 7 Professional or above to use XP Mode in this manner. Install XP Mode Make sure you’re logged in with Administrator rights for the entire process. The first thing you’ll want to do is install XP Mode on your system (link below). You don’t need to install Windows Virtual PC. Go through and install XP Mode using the defaults. Install VirtualBox Next you’ll need to install VirtualBox 3.1.2 or higher if it isn’t installed already. If you have an older version of VirtualBox installed, make sure to update it. During setup you’re notified that your network connection will be reset. Check the box next to Always trust software from “Sun Microsystems, Inc.” then click Install.   Setup only takes a couple of minutes, and does not require a reboot…which is always nice. Install VMLite XP Mode Plugin The next thing we’ll need to install is the VMLite XP Mode Plugin. Again Installation is simple following the install wizard. During the install like with VirtualBox you’ll be asked to install the device software. After it’s installed go to the Start menu and run VMLite Wizard as Administrator. Select the location of the XP Mode Package which by default should be in C:\Program Files\Windows XP Mode. Accept the EULA…and notice that it’s meant for Windows 7 Professional, Enterprise, and Ultimate editions. Next, name the machine, choose the install folder, and type in a password. Select if you want Automatic Updates turned on or not. Wait while the process completes then click Finish.   The VMLite XP Mode will set up to run the first time. That is all there is to this section. You can run XP Mode from within the VMLite Workstation right away. XP Mode is fully activated already, and the Guest Additions are already installed, so there’s nothing else you need to do!  XP Mode is the whole way ready to use. Integration with VirtualBox Since we installed the VMLite Plugin, when you open VirtualBox you’ll see it listed as one of your machines and you can start it up from here.   Here we see VMLite XP Mode running in Sun VirtualBox. Integrate with Windows 7 To integrate it with Windows 7 click on Machine \ Seamless Mode…   Here you can see the XP menu and Taskbar will be placed on top of Windows 7. From here you can access what you need from XP Mode.   Here we see XP running on Virtual Box in Seamless Mode. We have the old XP WordPad sitting next to the new Windows 7 version of WordPad. This works so seamlessly you forget if your working in XP or Windows 7. In this example we have Windows Home Server Console running in Windows 7, while installing MSE from IE 6 in XP Mode. At the top of the screen you will still have access to the VMs controls.   You can click the button to exit Seamless Mode, or simply hit the right “CTRL+L” Conclusion This is a very slick way to run XP Mode in VirtualBox on any machine that doesn’t have Hardware Virtualization. This method also doesn’t lose the XP Mode activation and is actually extremely easy to set up. If you prefer VMware (like we do), Check out how to run XP Mode on machines without Hardware Virtualization capability, and also how to create an XP Mode for Vista and Windows 7 Home Premium.

At the top of the screen you will still have access to the VMs controls.   You can click the button to exit Seamless Mode, or simply hit the right “CTRL+L” Conclusion This is a very slick way to run XP Mode in VirtualBox on any machine that doesn’t have Hardware Virtualization. This method also doesn’t lose the XP Mode activation and is actually extremely easy to set up. If you prefer VMware (like we do), Check out how to run XP Mode on machines without Hardware Virtualization capability, and also how to create an XP Mode for Vista and Windows 7 Home Premium.

• Install usblib package - Ubuntu

  - by Tom celic

  I need the package libusb for another package I am installing. I tried the following which seemed to install the package, sudo apt-get install libusb-dev but when I try to install the other package I get, configure: error: Package requirements (libusb-1.0 >= 0.9.1) were not met: No package 'libusb-1.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBUSB_CFLAGS and LIBUSB_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. When I run the command dpkg -L libusb-dev, I get: /. /usr /usr/bin /usr/bin/libusb-config /usr/include /usr/include/usb.h /usr/lib /usr/lib/libusb.a /usr/lib/libusb.la /usr/lib/pkgconfig /usr/lib/pkgconfig/libusb.pc /usr/share /usr/share/doc /usr/share/doc/libusb-dev /usr/share/doc/libusb-dev/html /usr/share/doc/libusb-dev/html/index.html /usr/share/doc/libusb-dev/html/preface.html /usr/share/doc/libusb-dev/html/intro.html /usr/share/doc/libusb-dev/html/intro-overview.html /usr/share/doc/libusb-dev/html/intro-support.html /usr/share/doc/libusb-dev/html/api.html /usr/share/doc/libusb-dev/html/api-device-interfaces.html /usr/share/doc/libusb-dev/html/api-timeouts.html /usr/share/doc/libusb-dev/html/api-types.html /usr/share/doc/libusb-dev/html/api-synchronous.html /usr/share/doc/libusb-dev/html/api-return-values.html /usr/share/doc/libusb-dev/html/functions.html /usr/share/doc/libusb-dev/html/ref.core.html /usr/share/doc/libusb-dev/html/function.usbinit.html /usr/share/doc/libusb-dev/html/function.usbfindbusses.html /usr/share/doc/libusb-dev/html/function.usbfinddevices.html /usr/share/doc/libusb-dev/html/function.usbgetbusses.html /usr/share/doc/libusb-dev/html/ref.deviceops.html /usr/share/doc/libusb-dev/html/function.usbopen.html /usr/share/doc/libusb-dev/html/function.usbclose.html /usr/share/doc/libusb-dev/html/function.usbsetconfiguration.html /usr/share/doc/libusb-dev/html/function.usbsetaltinterface.html /usr/share/doc/libusb-dev/html/function.usbresetep.html /usr/share/doc/libusb-dev/html/function.usbclearhalt.html /usr/share/doc/libusb-dev/html/function.usbreset.html /usr/share/doc/libusb-dev/html/function.usbclaiminterface.html /usr/share/doc/libusb-dev/html/function.usbreleaseinterface.html /usr/share/doc/libusb-dev/html/ref.control.html /usr/share/doc/libusb-dev/html/function.usbcontrolmsg.html /usr/share/doc/libusb-dev/html/function.usbgetstring.html /usr/share/doc/libusb-dev/html/function.usbgetstringsimple.html /usr/share/doc/libusb-dev/html/function.usbgetdescriptor.html /usr/share/doc/libusb-dev/html/function.usbgetdescriptorbyendpoint.html /usr/share/doc/libusb-dev/html/ref.bulk.html /usr/share/doc/libusb-dev/html/function.usbbulkwrite.html /usr/share/doc/libusb-dev/html/function.usbbulkread.html /usr/share/doc/libusb-dev/html/ref.interrupt.html /usr/share/doc/libusb-dev/html/function.usbinterruptwrite.html /usr/share/doc/libusb-dev/html/function.usbinterruptread.html /usr/share/doc/libusb-dev/html/ref.nonportable.html /usr/share/doc/libusb-dev/html/function.usbgetdrivernp.html /usr/share/doc/libusb-dev/html/function.usbdetachkerneldrivernp.html /usr/share/doc/libusb-dev/html/examples.html /usr/share/doc/libusb-dev/html/examples-code.html /usr/share/doc/libusb-dev/html/examples-tests.html /usr/share/doc/libusb-dev/html/examples-other.html /usr/share/doc/libusb-dev/copyright /usr/share/doc-base /usr/share/doc-base/libusb-dev /usr/share/man /usr/share/man/man1 /usr/share/man/man1/libusb-config.1.gz /usr/lib/libusb.so /usr/share/doc/libusb-dev/changelog.Debian.gz Any ideas??

• Geek Fun: Virtualized Old School Windows – Windows 95

  - by Matthew Guay

  Last week we enjoyed looking at Windows 3.1 running in VMware Player on Windows 7.  Today, let’s upgrade our 3.1 to 95, and get a look at how most of us remember Windows from the 90’s. In this demo, we’re running the first release of Windows 95 (version 4.00.950) in VMware Player 3.0 running on Windows 7 x64.  For fun, we ran the 95 upgrade on the 3.1 virtual machine we built last week. Windows 95 So let’s get started.  Here’s the first setup screen.  For the record, Windows 95 installed in about 15 minutes or less in VMware in our test. Strangely, Windows 95 offered several installation choices.  They actually let you choose what extra parts of Windows to install if you wished.  Oh, and who wants to run Windows 95 on your “Portable Computer”?  Most smartphones today are more powerful than the “portable computers” of 95. Your productivity may vastly increase if you run Windows 95.  Anyone want to switch? No, I don’t want to restart … I want to use my computer! Welcome to Windows 95!  Hey, did you know you can launch programs from the Start button? Our quick spin around Windows 95 reminded us why Windows got such a bad reputation in the ‘90’s for being unstable.  We didn’t even get our test copy fully booted after installation before we saw our first error screen.  Windows in space … was that the most popular screensaver in Windows 95, or was it just me? Hello Windows 3.1!  The UI was still outdated in some spots.   Ah, yes, Media Player before it got 101 features to compete with iTunes. But, you couldn’t even play CDs in Media Player.  Actually, CD player was one program I used almost daily in Windows 95 back in the day. Want some new programs?  This help file about new programs designed for Windows 95 lists a lot of outdated names in tech.    And, you really may want some programs.  The first edition of Windows 95 didn’t even ship with Internet Explorer.   We’ve still got Minesweeper, though! My Computer had really limited functionality, and by default opened everything in a new window.  Double click on C:, and it opens in a new window.  Ugh. But Explorer is a bit more like more modern versions. Hey, look, Start menu search!  If only it found the files you were looking for… Now I’m feeling old … this shutdown screen brought back so many memories … of shutdowns that wouldn’t shut down! But, you still have to turn off your computer.  I wonder how many old monitors had these words burned into them? So there’s yet another trip down Windows memory lane.  Most of us can remember using Windows 95, so let us know your favorite (or worst) memory of it!  At least we can all be thankful for our modern computers and operating systems today, right?  Similar Articles Productive Geek Tips Geek Fun: Remember the Old-School SkiFree Game?Geek Fun: Virtualized old school Windows 3.11Stupid Geek Tricks: Tile or Cascade Multiple Windows in Windows 7Stupid Geek Tricks: Select Multiple Windows on the TaskbarHow to Delete a System File in Windows 7 or Vista TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional Enable Check Box Selection in Windows 7 OnlineOCR – Free OCR Service Betting on the Blind Side, a Vanity Fair article 30 Minimal Logo Designs that Say More with Less LEGO Digital Designer – Free Create a Personal Website Quickly using Flavors.me

• Share a Printer on Your Network from Vista or XP to Windows 7

  - by Mysticgeek

  The other day we looked at sharing a printer between Windows 7 machines, but you may only have one Windows 7 machine and the printer is connected to a Vista or XP computer. Today we show you how to share a printer from either Vista or XP to Windows 7. We previously showed you how to share files and printers between Windows 7 and XP. But what if you have a printer connected to an XP or Vista machine in another room, and you want to print to it from Windows 7? This guide will walk you through the process. Note: In these examples we’re using 32-bit versions of Windows 7, Vista, and XP on a basic home network. We are using an HP PSC 1500 printer, but keep in mind every printer is different so finding and installing the correct drivers will vary. Share a Printer from Vista To share the printer on a Vista machine click on Start and enter printers into the search box and hit Enter. Right-click on the printer you want to share and select Sharing from the context menu. Now in Printer Properties, select the Sharing tab, mark the box next to Share this printer, and give the printer a name. Make sure the name is something simple with no spaces then click Ok. Share a Printer from XP To share a printer from XP click on Start then select Printers and Faxes. In the Printers and Faxes window right-click on the printer to share and select Sharing. In the Printer Properties window select the Sharing tab and the radio button next to Share this printer and give it a short name with no spaces then click Ok. Add Printer to Windows 7 Now that we have the printer on Vista or XP set up to be shared, it’s time to add it to Windows 7. Open the Start Menu and click on Devices and Printers. In Devices and Printers click on Add a printer. Next click on Add a network, wireless or Bluetooth printer. Windows 7 will search for the printer on your network and once its been found click Next. The printer has been successfully added…click Next. Now you can set it as the default printer and send a test page to verify everything works. If everything is successful, close out of the add printer screens and you should be good to go.   Alternate Method If the method above doesn’t work, you’ll can try the following for either XP or Vista. In our example, when trying to add the printer connected to our XP machine, it wasn’t recognized automatically. If you’re search pulls up nothing then click on The printer that I want isn’t listed. In the Add Printer window under Find a printer by name or TCP/IP address click the radio button next to Select a shared printer by name. You can either type in the path to the printer or click on Browse to find it. In this instance we decided to browse to it and notice we have 5 computers found on the network. We want to be able to print to the XPMCE computer so we double-click on that. Type in the username and password for that computer… Now we see the printer and can select it. The path to the printer is put into the Select a shared printer by name field. Wait while Windows connects to the printer and installs it… It’s successfully added…click Next. Now you can set it as the default printer or not and print a test page to make sure everything works successfully. Now when we go back to Devices and Printers under Printers and Faxes, we see the HP printer on XPMCE. Conclusion Sharing a printer from one machine to another can sometimes be tricky, but the method we used here in our setup worked well. Since the printer we used is fairly new, there wasn’t a problem with locating any drivers for it. Windows 7 includes a lot of device drivers already so you may be surprised on what it’s able to install. Your results may vary depending on your type of printer, Windows version, and network setup. This should get you started configuring the machines on your network—hopefully with good results.  If you you have two Windows 7 computers, then sharing a printer or files is easy through the Homegroup feature. You can also share a printer between Windows 7 machines on the same network but not Homegroup.

• Using jQuery, CKEditor, AJAX in ASP.NET MVC 2

  - by Ray Linder

  After banging my head for days on a “A potentially dangerous Request.Form value was detected" issue when post (ajax-ing) a form in ASP.NET MVC 2 on .NET 4.0 framework using jQuery and CKEditor, I found that when you use the following: Code Snippet $.ajax({     url: '/TheArea/Root/Add',     type: 'POST',     data: $("#form0Add").serialize(),     dataType: 'json',     //contentType: 'application/json; charset=utf-8',     beforeSend: function ()     {         pageNotify("NotifyMsgContentDiv", "MsgDefaultDiv", '<img src="/Content/images/content/icons/busy.gif" /> Adding post, please wait...', 300, "", true);         $("#btnAddSubmit").val("Please wait...").addClass("button-disabled").attr("disabled", "disabled");     },     success: function (data)     {         $("#btnAddSubmit").val("Add New Post").removeClass("button-disabled").removeAttr('disabled');         redirectToUrl("/Exhibitions");     },     error: function ()     {         pageNotify("NotifyMsgContentDiv", "MsgErrorDiv", '<img src="/Content/images/content/icons/cross.png" /> Could not add post. Please try again or contact your web administrator.', 6000, "normal");         $("#btnAddSubmit").val("Add New Post").removeClass("button-disabled").removeAttr('disabled');     } }); Notice the following: Code Snippet data: $("#form0Add").serialize(), You may run into the “A potentially dangerous Request.Form value was detected" issue with this. One of the requirements was NOT to disable ValidateRequest (ValidateRequest=”false”). For this project (and any other project) I felt it wasn’t necessary to disable ValidateRequest. Note: I’ve search for alternatives for the posting issue and everyone and their mothers continually suggested to disable ValidateRequest. That bothers me – a LOT. So, disabling ValidateRequest is totally out of the question (and always will be).  So I thought to modify how the “data: “ gets serialized. the ajax data fix was simple, add a .html(). YES!!! IT WORKS!!! No more “potentially dangerous” issue, ajax form posts (and does it beautifully)! So if you’re using jQuery to $.ajax() a form with CKEditor, remember to do: Code Snippet data: $("#form0Add").serialize().html(), or bad things will happen. Also, don’t forget to set Code Snippet config.htmlEncodeOutput = true; for the CKEditor config.js file (or equivalent). Example: Code Snippet CKEDITOR.editorConfig = function( config ) {     // Define changes to default configuration here. For example:     // config.language = 'fr';     config.uiColor = '#ccddff';     config.width = 640;     config.ignoreEmptyParagraph = true;     config.resize_enabled = false;     config.skin = 'kama';     config.enterMode = CKEDITOR.ENTER_BR;       config.toolbar = 'MyToolbar';     config.toolbar_MyToolbar =     [         ['Bold', 'Italic', 'Underline'],         ['JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock', 'Font', 'FontSize', 'TextColor', 'BGColor'],         ['BulletedList', 'NumberedList', '-', 'Outdent', 'Indent'],         '/',         ['Scayt', '-', 'Cut', 'Copy', 'Paste', 'Find'],         ['Undo', 'Redo'],         ['Link', 'Unlink', 'Anchor', 'Image', 'Flash', 'HorizontalRule'],         ['Table'],         ['Preview', 'Source']     ];     config.htmlEncodeOutput = true; }; Happy coding!!!

• Data Masking Pack 12.1.0.3 Certified with E-Business Suite 12.1.3

  - by Elke Phelps (Oracle Development)

  I'm pleased to announce the certification of the E-Business Suite 12.1.3 Data Masking Template for the Data Masking Pack with Enterprise Manager Cloud Control 12.1.0.3. You can use the Oracle Data Masking Pack with Oracle Enterprise Manager Grid Control 12c to scramble sensitive data in cloned E-Business Suite environments.     You may scramble data in E-Business Suite cloned environments with EM12.1.0.3 using the following template: E-Business Suite 12.1.3 Data Masking Template for Data Masking Pack with EM12c (Patch 18462641) What does data masking do in E-Business Suite environments? Application data masking does the following: De-identify the data:  Scramble identifiers of individuals, also known as personally identifiable information or PII.  Examples include information such as name, account, address, location, and driver's license number. Mask sensitive data:  Mask data that, if associated with personally identifiable information (PII), would cause privacy concerns.  Examples include compensation, health and employment information.   Maintain data validity:  Provide a fully functional application.  How can EBS customers use data masking? The Oracle E-Business Suite Template for Data Masking Pack can be used in situations where confidential or regulated data needs to be shared with other non-production users who need access to some of the original data, but not necessarily every table.  Examples of non-production users include internal application developers or external business partners such as offshore testing companies, suppliers or customers.  Due to data dependencies, scrambling E-Business Suite data is not a trivial task.  The data needs to be scrubbed in such a way that allows the application to continue to function. The template works with the Oracle Data Masking Pack and Oracle Enterprise Manager to obscure sensitive E-Business Suite information that is copied from production to non-production environments.  The Oracle E-Business Suite Template for Data Masking Pack is applied to a non-production environment with the Enterprise Manager Grid Control Data Masking Pack.  When applied, the Oracle E-Business Suite Template for Data Masking Pack will create an irreversibly scrambled version of your production database for development and testing. Is there a charge for this? Yes. You must purchase licenses for the Oracle Data Masking Pack to use the Oracle E-Business Suite 12.1.3 template. The Oracle E-Business Suite 12.1.3 Template for the Data Masking Pack is included with the Oracle Data Masking Pack license.  You can contact your Oracle account manager for more details about licensing.

• New HTML 5 input types in ASP.Net 4.5 Developer Preview

  - by sreejukg

  Microsoft has released developer previews for Visual Studio 2011 and .Net framework 4.5. There are lots of new features available in the developer preview. One of the most interested things for web developers is the support introduced for new HTML 5 form controls. The following are the list of new controls available in HTML 5 email url number range Date pickers (date, month, week, time, datetime, datetime-local) search color Describing the functionality for these controls is not in the scope of this article. If you want to know about these controls, refer the below URLs http://msdn.microsoft.com/en-us/magazine/hh547102.aspx http://www.w3schools.com/html5/html5_form_input_types.asp ASP.Net 4.5 introduced more possible values to the Text Mode attribute to cater the above requirements. Let us evaluate these. I have created a project in Visual Studio 2011 developer preview, and created a page named “controls.aspx”. In the page I placed on Text box control from the toolbox Now select the control and go to the properties pane, look at the TextMode attribute. Now you can see more options are added here than prior versions of ASP.Net. I just selected Email as TextMode. I added one button to submit my page. The screen shot of the page in Visual Studio 2011 designer is as follows See the corresponding markup <form id="form1" runat="server">     <div>         Enter your email:         <asp:TextBox ID="TextBox1" runat="server" TextMode="Email"></asp:TextBox     </div>     <asp:Button ID="Button1" runat="server" Text="Submit" /> </form> Now let me run this page, IE 9 do not have the support for new form fields. I browsed the page using Firefox and the page appears as below. From the source of the rendered page, I saw the below markup for my email textbox <input name="TextBox1" type="email" id="TextBox1" /> Try to enter an invalid email and you will see the browser will ask you to enter a valid one by default. When rendered in non-supported browsers, these fields are behaving just as normal text boxes. So make sure you are using validation controls with these fields. See the browser support compatability matrix with these controls with various browser vendors. ASP.Net 4.5 introduced the support for these new form controls. You can build interactive forms using the newly added controls, keeping in mind that you need to validate the data for non-supported browsers.

• Q&amp;A: Can you develop for the Windows Azure Platform using Windows XP?

  - by Eric Nelson

  This question has come up several times recently as we take several hundred UK developers through 6 Weeks of Windows Azure training (sorry – we are full). Short answer: In the main, yes Longer answer: The question is sparked by the requirements as stated on the Windows Azure SDK download page. Namely: Supported Operating Systems: Windows 7; Windows Vista; Windows Vista 64-bit Editions Service Pack 1; Windows Vista Business; Windows Vista Business 64-bit edition; Windows Vista Enterprise; Windows Vista Enterprise 64-bit edition; Windows Vista Home Premium; Windows Vista Home Premium 64-bit edition; Windows Vista Service Pack 1; Windows Vista Service Pack 2; Windows Vista Ultimate; Windows Vista Ultimate 64-bit edition Notice there is no mention of Windows XP. However things are not quite that simple. The Windows Azure Platform consists of three released technologies Windows Azure SQL Azure Windows Azure platform AppFabric The Windows Azure SDK is only for one of the three technologies, Windows Azure. What about SQL Azure and AppFabric? Well it turns out that you can develop for both of these technologies just fine with Windows XP: SQL Azure development is really just SQL Server development with a few gotchas – and for local development you can simply use SQL Server 2008 R2 Express (other versions will also work). AppFabric also has no local simulation environment and the SDK will install fine on Windows XP (SDK download) Actually it is also possible to do Windows Azure development on Windows XP if you are willing to always work directly against the real Azure cloud running in Microsoft datacentres. However in practice this would be painful and time consuming, hence why the Windows Azure SDK installs a local simulation environment. Therefore if you want to develop for Windows Azure I would recommend you either upgrade from Windows XP to Windows 7 or… you use a virtual machine running Windows 7. If this is a temporary requirement, then you could consider building a virtual machine using the Windows 7 Enterprise 90 day eval. Or you could download a pre-configured VHD – but I can’t quite find the link for a Windows 7 VHD. Pointers welcomed. Thanks.

• Updating the managed debugging API for .NET v4

  - by Brian Donahue

  In any successful investigation, the right tools play a big part in collecting evidence about the state of the "crime scene" as it was before the detectives arrived. Unfortunately for the Crash Scene Investigator, we don't have the budget to fly out to the customer's site, chalk the outline, and eat their doughnuts. We have to rely on the end-user to collect the evidence for us, which means giving them the fingerprint dust and the evidence baggies and leaving them to it. With that in mind, the Red Gate support team have been writing tools that can collect vital clues with a minimum of fuss. Years ago we would have asked for a memory dump, where we used to get the customer to run CDB.exe and produce dumps that we could analyze in-house, but those dumps were pretty unwieldy (500MB files) and the debugger often didn't dump exactly where we wanted, or made five or more dumps. What we wanted was just the minimum state information from the program at the time of failure, so we produced a managed debugger that captured every first and second-chance exception and logged the stack and a minimal amount of variables from the memory of the application, which could all be exported as XML. This caused less inconvenience to the end-user because it is much easier to send a 65KB XML file in an email than a 500MB file containing all of the application's memory. We don't need to have the entire victim shipped out to us when we just want to know what was under the fingernails. The thing that made creating a managed debugging tool possible was the MDbg Engine example written by Microsoft as part of the Debugging Tools for Windows distribution. Since the ICorDebug interface is a bit difficult to understand, they had kindly created some wrappers that provided an event-driven debugging model that was perfect for our needs, but .NET 4 applications under debugging started complaining that "The debugger's protocol is incompatible with the debuggee". The introduction of .NET Framework v4 had changed the managed debugging API significantly, however, without an update for the MDbg Engine code! After a few hours of research, I had finally worked out that most of the version 4 ICorDebug interface still works much the same way in "legacy" v2 mode and there was a relatively easy fix for the problem in that you can still get a reference to legacy ICorDebug by changing the way the interface is created. In .NET v2, the interface was acquired using the CreateDebuggingInterfaceFromVersion method in mscoree.dll. In v4, you must first create IClrMetaHost, enumerate the runtimes, get an ICLRRuntimeInfo interface to the .NET 4 runtime from that, and use the GetInterface method in mscoree.dll to return a "legacy" ICorDebug interface. The rest of the MDbg Engine will continue working the old way. Here is how I had changed the MDbg Engine code to support .NET v4: private void InitFromVersion(string debuggerVersion){if( debuggerVersion.StartsWith("v1") ){throw new ArgumentException( "Can't debug a version 1 CLR process (\"" + debuggerVersion + "\"). Run application in a version 2 CLR, or use a version 1 debugger instead." );} ICorDebug rawDebuggingAPI=null;if (debuggerVersion.StartsWith("v4")){Guid CLSID_MetaHost = new Guid("9280188D-0E8E-4867-B30C-7FA83884E8DE"); Guid IID_MetaHost = new Guid("D332DB9E-B9B3-4125-8207-A14884F53216"); ICLRMetaHost metahost = (ICLRMetaHost)NativeMethods.ClrCreateInterface(CLSID_MetaHost, IID_MetaHost); IEnumUnknown runtimes = metahost.EnumerateInstalledRuntimes(); ICLRRuntimeInfo runtime = GetRuntime(runtimes, debuggerVersion); //Defined in metahost.hGuid CLSID_CLRDebuggingLegacy = new Guid(0xDF8395B5, 0xA4BA, 0x450b, 0xA7, 0x7C, 0xA9, 0xA4, 0x77, 0x62, 0xC5, 0x20);Guid IID_ICorDebug = new Guid("3D6F5F61-7538-11D3-8D5B-00104B35E7EF"); Object res;runtime.GetInterface(ref CLSID_CLRDebuggingLegacy, ref IID_ICorDebug, out res); rawDebuggingAPI = (ICorDebug)res; }elserawDebuggingAPI = NativeMethods.CreateDebuggingInterfaceFromVersion((int)CorDebuggerVersion.Whidbey,debuggerVersion);if (rawDebuggingAPI != null)InitFromICorDebug(rawDebuggingAPI);elsethrow new ArgumentException("Support for debugging version " + debuggerVersion + " is not yet implemented");} The changes above will ensure that the debugger can support .NET Framework v2 and v4 applications with the same codebase, but we do compile two different applications: one targeting v2 and the other v4. As a footnote I need to add that some missing native methods and wrappers, along with the EnumerateRuntimes method code, came from the Mindbg project on Codeplex. Another change is that when using the MDbgEngine.CreateProcess to launch a process in the debugger, do not supply a null as the final argument. This does not work any more because GetCORVersion always returns "v2.0.50727" as the function has been deprecated in .NET v4. What's worse is that on a system with only .NET 4, the user will be prompted to download and install .NET v2! Not nice! This works much better: proc = m_Debugger.CreateProcess(ProcessName, ProcessArgs, DebugModeFlag.Default,String.Format("v{0}.{1}.{2}",System.Environment.Version.Major,System.Environment.Version.Minor,System.Environment.Version.Build)); Microsoft "unofficially" plan on updating the MDbg samples soon, but if you have an MDbg-based application, you can get it working right now by changing one method a bit and adding a few new interfaces (ICLRMetaHost, IEnumUnknown, and ICLRRuntimeInfo). The new, non-legacy implementation of MDbg Engine will add new, interesting features like dump-file support and by association I assume garbage-collection/managed object stats, so it will be well worth looking into if you want to extend the functionality of a managed debugger going forward.

• How to add event receiver to SharePoint2010 content type programmatically

  - by ybbest

  Today , I’d like to show how to add event receiver to How to add event receiver to SharePoint2010 content type programmatically. 1. Create empty SharePoint Project and add a class called ItemContentTypeEventReceiver and make it inherit from SPItemEventReceiver and implement your logic as below public class ItemContentTypeEventReceiver : SPItemEventReceiver { private bool eventFiringEnabledStatus; public override void ItemAdded(SPItemEventProperties properties) { base.ItemAdded(properties); UpdateTitle(properties); } private void UpdateTitle(SPItemEventProperties properties) { SPListItem addedItem = properties.ListItem; string enteredTitle = addedItem["Title"] as string; addedItem["Title"] = enteredTitle + " Updated"; DisableItemEventsScope(); addedItem.Update(); EnableItemEventsScope(); } public override void ItemUpdated(SPItemEventProperties properties) { base.ItemUpdated(properties); UpdateTitle(properties); } private void DisableItemEventsScope() { eventFiringEnabledStatus = EventFiringEnabled; EventFiringEnabled = false; } private void EnableItemEventsScope() { eventFiringEnabledStatus = EventFiringEnabled; EventFiringEnabled = true; } } 2.Create a Site or Web(depending or your requirements) scoped feature and implement your feature event handler as below: public override void FeatureActivated(SPFeatureReceiverProperties properties) { SPWeb web = GetFeatureWeb(properties); //http://karinebosch.wordpress.com/walkthroughs/event-receivers-theory/ string assemblyName =  System.Reflection.Assembly.GetExecutingAssembly().FullName; const string className = "YBBEST.AddEventReceiverToContentType.ItemContentTypeEventReceiver"; SPContentType contentType= web.ContentTypes["Item"]; AddEventReceiverToContentType(className, contentType, assemblyName, SPEventReceiverType.ItemAdded, SPEventReceiverSynchronization.Asynchronous); AddEventReceiverToContentType(className, contentType, assemblyName, SPEventReceiverType.ItemUpdated, SPEventReceiverSynchronization.Asynchronous); contentType.Update(); } protected static void AddEventReceiverToContentType(string className, SPContentType contentType, string assemblyName, SPEventReceiverType eventReceiverType, SPEventReceiverSynchronization eventReceiverSynchronization) { if (className == null) throw new ArgumentNullException("className"); if (contentType == null) throw new ArgumentNullException("contentType"); if (assemblyName == null) throw new ArgumentNullException("assemblyName"); SPEventReceiverDefinition eventReceiver = contentType.EventReceivers.Add(); eventReceiver.Synchronization = eventReceiverSynchronization; eventReceiver.Type = eventReceiverType; eventReceiver.Assembly = assemblyName; eventReceiver.Class = className; eventReceiver.Update(); } 3.Deploy your solution and now you have a event receiver that attached to the Item contentType. You can download the complete source code here.You can also check how to add event receiver to a list using SharePoint event receiver item in Visual Studio2010 in my previous blog.
