  • Why can't my Wifi connect or disconnect?

    - by tmy1018
    Wifi connection might drop spontaneously or simply cannot connect. Users on Ubuntu 10.04 and 11.04 have reported experiencing the problem. Running dmesg would show: [210749.637705] wlan0: deauthenticating from 00:23:89:48:3b:b0 by local choice (reason=3) [210778.632244] wlan0: deauthenticating from 00:23:89:48:3b:b0 by local choice (reason=3) [210784.456359] wlan0: deauthenticating from 00:23:89:82:75:70 by local choice (reason=3) which is pretty cryptic. I have tried: kill -9 wpa_supplicant, but wpa_supplicant keeps getting restarted each time. Also, some have suggested that this was caused by enabling power management. However, this might not be true, as the problem has presented itself in a situation where power management was disabled.

  • Oracle Virtualization Friday Spotlight - November 8, 2013

    - by Monica Kumar
    Hands-on Private Cloud Simulator In One Hour Submitted by: Doan Nguyen, Senior Principal Product Marketing Director My aeronautics instructor used to say, "you can’t appreciate flying until you take flight." To clarify, this is not about gearing up in a flying squirrel suit and hopping off a cliff (topic for another blog!) but rather about flying an airplane. The idea is to get hands-on with the controls at the cockpit and experience flight before you actually fly a real plane. After the initial 40 hours of flight time, the concept sank in and it really made sense.This concept is what inspired our technical experts to put together the hands-on lab for a private cloud deployment and management self-service model. Yes, we are comparing the lab to a flight simulator! Let’s look at the parallels: To get trained to fly, starting in the simulator gets you off the ground quicker. There is no need to have a real plane to begin with. In a hands-on lab, there is no need for a real server, with networking and real storage installed. All you need is your laptop The simulator is pre-configured, pre-flight check done. Similarly, in a hands-on lab, Oracle VM and Oracle Enterprise Manager are pre-configured and assembled using Oracle VM VirtualBox as the container. Software installations are not needed. After time spent training at the controls, you can really appreciate the practical experience of flying. Along the same lines, the hands-on lab is a guided learning path, without the encumbrances of hardware, software installation, so you can learn about cloud deployment and management.  However, unlike the simulator training, your time investment with the lab is only about an hour and not 40 hours! This hands-on lab takes you through private cloud deployment and management using Oracle VM and  Oracle Enterprise Manager Cloud Control 12c in an Infrastructure as a service IaaS model. You will first configure the IaaS cloud as the cloud administrator and then deploy guest virtual machines (VMs) as a self-service user. Then you are ready to take flight into the cloud! Why not step into the cockpit now!

  • Ubuntu installer thinks my drive is empty, does not see windows paritions.

    - by John
    Hello, I am trying to install Ubuntu10.10 64bit. I just installed Windows 7 64bit moments ago. My drive is currently partitioned like so: 100MB Boot partition (automatically made by windows 7 installer) 390GB Windows partition ~1.6TB free space When I go through the Ubuntu installer it does not give me the option to install alongside another operating system. My only options are to use the entire disk or to specify partitions manually. When I chose to specify partitions manually it tells me that the drive is all free space! Windows is still booting and behaving normally, and I had not doing anything in Windows yet (had simply installed, booted for first time, then immediately restarted). I am even able to mount the windows partition within Ubuntu Live CD, and see it in the disk viewer (not gparted). Gparted in Ubuntu Live CD again reports no partitions, all free space. Not sure what to do :S. I have installed Windows7 alongside Ubuntu countless times, even Ubuntu 10.10. Thank you very much for your help :).

  • Reading the tea leaves from Windows Azure support

    - by jamiet
    A few idle thoughts… Three months ago I had an issue regarding Windows Azure where I was unable to login to the management portal. At the time I contacted Azure support, the issue was soon resolved and I thought no more about it. Until today that is when I received an email from Azure support providing a detailed analysis of the root cause, the fix and moreover precise details about when and where things occurred. The email itself is interesting and I have included the entirety of it below. A few things were interesting to me: The level of detail and the diligence in investigating and reporting the issue I found really rather impressive. They even outline the number of users that were affected (127 in case you can’t be bothered reading). Compare this to the quite pathetic support that another division within Microsoft, Skype, provided to Greg Low recently: Skype support and dead parrot sketches   This line: “Windows Azure performed a planned change from using the Microsoft account service (formerly Windows Live ID) to the Azure Active Directory (AAD) as its primary authentication mechanism on August 24th. This change was made to enable future innovation in the area of authentication – particularly for organizationally owned identities, identity federation, stronger authentication methods and compliance certification. ” I also found to be particularly interesting. I have long thought that one of the reasons Microsoft has proved to be such a money-making machine in the enterprise is because they provide the infrastructure and then upsell on top of that – and nothing is more infrastructural than Active Directory. It has struck me of late that they are trying to make the same play of late in the cloud by tying all their services into Azure Active Directory and here we see a clear indication of that by making AAD the authentication mechanism for anyone using Windows Azure. I get the feeling that we’re going to hear much much more about AAD in the future; isn’t it about time we could log on to SQL Azure Windows Azure SQL Database without resorting to SQL authentication, for example? And why do Microsoft have two identity providers – Microsoft Account (aka Windows Live ID) and AAD – isn’t it about time those things were combined? As I said, just some idle thoughts. Below is the transcript of the email if you are interested. @Jamiet  This is regarding the support request <redacted> where in you were not able to login into the windows azure management portal with live id. We are providing you with the summary, root cause analysis and information about permanent fix: Incident Title: You were unable to access Windows Azure Portal after Microsoft Account to Azure Active Directory account Migration. Service Impacted: Management Portal Incident Start Date and Time: 8/24/2012 4:30:00 PM Date and Time Service was Restored: 10/17/2012 12:00:00 AM Summary: Windows Azure performed a planned change from using the Microsoft account service (formerly Windows Live ID) to the Azure Active Directory (AAD) as its primary authentication mechanism on August 24th.   This change was made to enable future innovation in the area of authentication – particularly for organizationally owned identities, identity federation, stronger authentication methods and compliance certification.   While this migration was largely transparent to Windows Azure users, a small number of users whose sign-in names were part of a Windows Live Custom Domain were unable to login.   This incompatibility was not discovered during the Quality Assurance testing phase prior to the migration. Customer Impact: Customers whose sign-in names were part of a Windows Live Custom Domain were unable to sign-in the Management Portal after ~4:00 p.m. PST on August 24th, 2012.   We determined that the issue did impact at least 127 users in 98 of these Windows Live Custom Domains and had a maximum potential impact of 1,110 users in total. Root Cause: The root cause of the issue was an incompatibility in the AAD authentication service to handle logins from Microsoft accounts whose sign-in names were part of a Windows Live Custom Domains.  This issue was not discovered during the Quality Assurance testing phase prior to the migration from Microsoft Account (MSA) to AAD. Mitigations: The issue was mitigated for the majority of affected users by 8:20 a.m. PST on August 25th, 2012 by running some internal scripts to correct many known Windows Live Custom Domains.   The remaining affected domains fell into two categories: Windows Live Custom Domains that were not corrected by 8/25/2012. An additional 48 Windows Live Custom Domains were fixed in the weeks following the incident within 2 business days after the AAD team received an escalation from product support regarding those accounts. Windows Live Custom domains that were also provisioned in Office365. Some of the affected Windows Live Custom Domains had already been provisioned in AAD because their owners signed up for Office365 which is a service that also uses AAD.   In these cases the Azure customers had to work around the issue by renaming their Microsoft Account or using a different Microsoft Account to administer their Azure subscription. Permanent Fix: The Azure Active Directory team permanently fixed the issue for all customers on 10/17/2012 in an upgraded release of the AAD service.

  • How to create a bootable USB stick?

    - by Deborah Shadovitz
    I am looking at this: http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu I need to create a boot disk to test Ubuntu to make sure it will run on a PC (Compaq Mini CQ10-120LA) I was given. I can create the boot disk off of a Mac (in English) or Windows (but Windows is in Spanish and foreign to me). Questions: What format do I choose for the USB stick? (I wish the instructions stated this). What is Dash? (Will I know when I run the installer?) Can I do this from a Mac or Windows computer? Or only from Ubuntu?

  • Can't mount external hard drive

    - by tezza
    i have a problem accessing the data on my external hard drive. I recently did a fresh install but mistakenly left my external hard drive plugged in. When I tried to access the data on the external HDD, it says "no files" but recognizes that there is 290 GiB of data on it. The HDD is 350GB big. I checked the drive with Disk Utility and it showed that the hard drive had a bootable flag. So, in the edit partition, I unchecked this bootablity. Now it won't mount in Ubuntu and now my XP can't recognize it at all, whereas I could access the data on the XP machine before. In disk utility, it doesn't give me the option to check the bootable box in again and I can't access the data on XP either. Any ideas on how to fix it?

  • S11 launched

    - by unixman
    Now that Oracle Solaris 11 is out, its time to do 2 things -- 1) Its time to see what's in it, what's new and why its important, and then assess why it might make sense to begin evaluating it for your needs and 2) Its time to acknowledge, give thanks to and congratulate all the R&D personnel, architects, engineers, designers and testers who've put in so much effort and energy into helping make Solaris 11 (and SunOS 5.11) what it has become -- starting way back circa 2004 and, more importantly, culminating in the recent years and months -- staying focused on the execution, unwavering in the face of various challenges. For #1 above, here are a few good things to get going with - Watch the product launch replay - Visit the Solaris 11 Spotlight section on oracle.com - Get comfortable through introductory videos and detailed "how-to" guides (ex: how to create and publish IPS packages), white papers on the new default root file system, ZFS, and reap the benefits brought on by the fundamental shift in easing the administration experience - Look at the next level of software lifecycle management that is enabled by technologies such as Automated Installer and Image Packaging System -- that dramatically address patch management-related challenges - Understand how we continue to innovate in areas of service intelligence, reliability and availability - Start to evaluate enhancements in virtualization capabilities -- whether influenced by the need to consolidate or motivated by the need to have increased service mobility across physical systems, leveraging hardware-level abstractions - Gain more control over your network-centric services through enhancements in network resource management, observability and I/O performance - Look beyond your existing infrastructure with confidence that you can re-host and transition to newer systems with the use of Solaris 10 zones running on top of Solaris 11 - Relish in the fact that you can do all this, get your data to be secure and encrypted and more, on both, SPARC and x86-based systems. - Stay informed by keeping an eye on relevant blogs, which we've begun turning up recently. - Go through a hands-on lab - Sign up to take a class or just opt to watch various videos to begin to raise your comfort level with these technologies For #2 above -- There are many ways to do that. One way is to just say "thanks" with an email, a post, or a simple card,  similar to this one seen at a Barnes and Noble store recently.  The front of the card is followed by what's inside... and as the saying goes, now more then ever "it's what's inside that counts" And here's the inside of the card: So, what are you waiting for ? Go download and try it out, and please let us know what you think of it!

  • Dealing with technical debt

    - by Desolate Planet
    This is a question that I often ask myself when working with developers. I've worked at four companies so far, and I've noticed a lack of attention to keeping code clean and dealing with technical debt that hinders future progress in a software app. For example, the first company I worked for had written a database from scratch rather than take something like MySQL and that created hell for the team when refacoring or extending the app. I've always tried to be honest and clear with my manager when he discusses projections, but management doesn't seem interested in fixing what's already there and it's horrible to see the impact it has on team morale and in their attitude towards others. What are your thoughts on the best way to tackle this problem? What I've seen is people packing up and leaving and the company becomes a revolving door with developers coming and and out and making the code worse. How do you communicate this to management to get them interested in sorting out technical debt?

  • The partition table is corrupt

    - by Tim
    I have a corrupt the partition table on the laptop that is running Ubunutu 10.4. Before the partition table was corrupt I had the following partitions: 2 primary partitions: 1st - NTFS 2nd - Extended 4 logical partitons that are built within 2nd extended: 1st NTFS (68 Gib) 2nd Linux (19 Gib) 3rd Swap (1.4 Gib) 4th Linux (24 Gib) The physical order of these partitions was the following: ( 4th Linux ) - ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) The logical order of the partition was different: ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) ( 4th Linux ) NTFS partition was big and it resided between 2 Linux partitions, neither of these partitions had enough space to install Oracle 11g. Therefore, I decided to a) either move the NTFS partion to the left or b) remove it completely and extend partition where Linux resides. As I tool I have chosen GParted. But unfortunately it was not able to move the partition because he found that in NTFS partition there are some blocks that are referenced multiple times. Also it was not able to remove the partition neither, because in this case the partitions that follow it ( 2nd Linux ) - ( 3rd Swap ) have to be in his opinion also removed, because the organization of extended partition is a linked list. Since GParted was not able to do such thing I was trying to find another tool. I found diskdrake tool on PSLinuxOS distribution of linux. That tool silently deleted ( 1st NTFS ) partition and I thought that everything was fine. But diskdrake has damaged the partition in a way that I am not able either to boot from the hard disk nor to see the partitions with GParted and even with diskdrake itself! Fortunately I have a live CD of Ubuntu 8.10 and I am able to boot and see hard disk. I have 2 ideas how I can solve the problem: 1) Manually change disk partitions and point them to the correct partitions. 2) Create partition table with GParted that as much as possible is the same with the previous one I find the 2nd approach less time consuming but some data will be lost because of it is not possible to place borders of the partitions exactly how it was before. And moreover I am not sure if such approach would work, for example, if the OS is able to locate files after repartitioning. I feel like that it will but not 100% sure. Are there some ideas how the problem may be solved?

  • Introducing Task-It. A real-world application using RadControls for Silverlight 4

    This is the first in a series of blog posts based around an application called Task-It that I have developed in Silverlight 4. Task-It is real-world application designed for people that need a simple way to manage the numerous tasks that we all strive to accomplish on a daily basis.

  • Ubuntu 13.XX unable to mount USB HDD. Tried everything. I/O error boot sector/file system

    - by XaviGG
    I know that there are many posts related but none of them helped me. I will jump to the last test because it is the one that should work, but it does not. An external HDD with single partition slow NTFS formatted in Windows, empty and clean. Checked for errors, it tells that not errors where found. Moving to Ubutnu 13.04... Gparted throws the first error when trying to read the disk: Input/output error It appears as unknown the content of the disk. Unable to create partition table or format it, getting the same error when trying. If I try to mount it in the terminal it tells me the same, specifying that also there is an I/O error reading the boot sector. I have this problem since I upgraded (always with fresh install) to 13.04. I thought it will be solved by the 13.10 but it has the same behavior. I tried with two different HDD (HD and SSHD) that work perfectly in Windows 7. In 13.04 at least I got a trying of mounting where the icon of the drive started showing and disappearing until finally it disappeared. But now it doesn't even try. Possible causes: -The HDD was my old main HDD, so it had WIN,RECOVERY,SYSTEM,UBU,SWAP partitions. Maybe the way or place where the partition table is defined is not the best for an external HDD but I don't know a lot in that topic. I would appreciate a lot if someone can give me a guideline to convert one of these HDD in a working external HDD. No files to recover, nothing to care about. Just format completely the disk and be able to use it for storing backups without having to move the files first to the windows partition, load windows and then copy them to the external HDD. Because I want to use a file comparator for the backups. Thanks a lot Edit 1: I found an option in Windows to convert it to a dynamic HDD that warns me that I wont be able to run O.S. after changing. I suppose that is what I need because in the current mode I cannot safely extract it. But it tells me an error that it couldn't change the mode.

  • Half the time Linux drop into BusyBox; the rest of the time the boot happens normally

    - by JoBu1324
    I just installed Ubuntu x64 onto a USB3 Drive from a DVD, and half the time it appears to skip the grub menu and boots directly into BusyBox. Since the USB3 drive is an SSD, I ran through the full installation (installing on an ext4 partition, along side a 1GB boot partition at the start of the disk), skipping the swap partition. Part of the time that the Grub Menu does shows, it boots into BusyBox with an error: ALERT! /dev/disk/by-uuid/[uid] does not exist. Dropping to a shell! What could cause such an issue?
