  • grub2 loopback booting ubuntu server iso

    - by Thermionix
    I've got usb-keys setup to multi-boot different linux images using grub2 loopback. The standard ubuntu release isos boot fine, however when attempting to use the server iso it will fail to install saying 'unable to detect cd-media for installation'. the grub.cfg entry; menuentry "ubuntu-12.04-server-amd64" { set isofile="/boot/ubuntu-12.04-server-amd64.iso" loopback loop $isofile linux (loop)/install/vmlinuz file=$isofile/preseed/ubuntu-server.seed ro noprompt noeject -- initrd (loop)/install/initrd.gz } I've attempted to add the following parameters as the fromiso works for debian images on the key iso-scan/filename=/boot/ubuntu-12.04-server-amd64.iso iso-scan/filename=/dev/disk/by-uuid/2859-44B7/boot/ubuntu-12.04-server-amd64.iso fromiso=/dev/disk/by-uuid/2859-44B7/boot/ubuntu-12.04-server-amd64.iso

  • How do I mount this HDD?

    - by Casval Deikun
    I have a Windows HDD attached to an external docking bay on my Ubuntu System, but the HDD brings up an error message: Mounting exited with exit code 14:windows is hibernated, refused to mount. Failed to mount '/dev/sde2':Operation not permitted. The NTFS partition is hibernated. Please resume and shutdown windows properly or mount the volume read-only with the 'ro' mount option, or mount the volume read-write with the 'remove_hiberfile' mount option. For example type in command line: mount -t ntfs-3g-o remove_hiberfile/dev/sde2/media/FE46D60C46D5C615 I am at a loss for exactly how to remove the hiberfile, or even mount it as read-only or read-write. I tried directly copy and pasting that exact command into my terminal, but it said: mount:only root can do that I do not know what to do at this point. I do need to get the information off of this drive, but I do not have a computer to put it in. Does anyone know what I should do from here?

  • Mounting Samsung Galaxy S2 via USB on Ubuntu 13.04

    - by argvar
    Connecting my Samsung Galaxy S2 to Windows 7 worked seamlessly. Now that I'm on Ubuntu 13.04 I'd like to access my phone's drive via the USB cable, but that's not working. When I do plug it in I get a error message in Ubuntu: Unable to mount SAMSUNG_Android Unable to open MTP device '[usb:002,008]' Then when I unplug it I see a error message on the phone: Attention Unable to find software on your PC that can recognize your device. Service pack 3, Windows Media Player, version 10 or higher, for Windows XP or Android FIle Transfer for Mac OS must be installed. You can download and install PC Kies from http://www.samsung.com/kies in order to sync data with your device, back up data, and upgrade your device (Windows and Mac OS are supported) What can I do here to fix this?

  • HD Video on Pandaboard ES

    - by Lord Loh.
    I am running Ubuntu 11.10 on my Pandaboard ES. I attempted to playback a 720p / 1080p video. In both cases, the videos were highly jittery and the audio seemed to be plagued with something that seemed to be white noise (sounds like white noise, but it definitely is not white noise). I was using VLC media player for playback and was running XFCE4 as the desktop ewnvironment. The system monitor graph indicates both the CPU cores running ~100%. Lower resolution videos seemed to play without problems. How do I play 1080 / 720 HD videos on pandaboard? Thanks in advance.

  • MP4 files show up but won't stream to xbox 360

    - by Greg
    I set up a basic media server to stream to my 360 using uShare. Here are the instructions I used: http://linuxexpresso.wordpress.com/2011/01/02/howto-ubuntu-upnp-server-to-xbox-360/. I can stream avi files fine but I cannot stream mp4s. When I go to videos on the xbox, I can see all of the videos and folders but when I click play for an mp4 nothing happens. On my ubuntu desktop I can click on the mp4 file and it plays fine. And if I take that file, stick it on a thumb drive and plug it directly into the xbox the mp4 will play off the thumb drive. I'm lost for why it won't work through ushare. Any ideas?

  • How can I get streaming radio working with Chromium on "fubar.com"?

    - by Jared Shirk
    I'm running 12.04 and use Chromium and a site that I go to that plays streaming radio doesn't seem to work for me. Python cannot find the right plug in and I was informed that the exact extension I need is for Windows Media Player HTML5 extension.. But alas, it doesn't work with Ubuntu.. is there a way around this so I can listen to the music? Fubar.com is a site that I've had for a while now and it just seems that any of the lounges that I go into, it's a chat room where they have live dj's that stream music. I can't get it to work.

  • How to increase ad revenue

    - by Brian515
    I have an Android game in which I've included ads from Millennial Media and Admob. Between these two networks, my fill rate is consistently above 95%. Right now, I'm getting over 45,000 requests for ads per day, and I'm starting to see exponential growth. But, my eCpm for both Millennial and Admob is ridiculously low. Millennial's is $.12 and Admob's is $.01. I've been reading some other posts and it seems like people are getting between $1 and $4 per 1,000 views. How can increase mine? Thank you!

  • Only MKV format available in HandBrake

    - by Steve Ellis
    I am running Ubuntu 14.04 LTS 32 bit. I have installed HandBrake rev5474 (i686), which I believe is the latest, and the Ubuntu Restricted Extras. I am able to play DVDs via VLC but when it comes to ripping them, so that I can back them up to my Twonky media server, I have issues. I launch HandBrake and find that the only format available for me to select is MKV. When I used to run Handbrake on this machine while I was running Ubuntu 13.10 and lower I had no issues and **lots of formats (including MP4 which is what I'm really after) but since reformating and installing 14.04 I've had this issue. Any help would be much appreciated.

  • Low graphics mode on Ubuntu 12.04 with Intel Graphics

    - by NightShadeQueen
    When I boot, my computer just tells me it can't detect graphic card (or something else) settings and it has to use the low graphics mode. Then it gives me four choices, but doesn't let me choose any of them. I can get my computer to boot by going to some sort of terminal mode and then typing sudo gdm. The other graphics manager I have is lightdm. I originally had the nVidia propriety driver, and I've tried bumblebee. Mobile Intel Graphics Media Accelerator 4500M is my graphics card. Is there any way to fix this so I can use lightdm again?

  • bash profile works for user but not sudo

    - by user564448
    I've modified my .profile to include a folder if a flash drive is plugged in. When running the command as the user it works fine but tells me the scrip must be run by sudo (this is what i want). However, when i try to run it with sudo i get "command not found" I have a symlink (flash) in my /var/www folder pointing to my /media/flash drive. (nevermind this setup since is just for dev) this is my user's .profile : # set PATH so it includes flash scripts if [ -d "/var/www/flash/scripts" ] ; then PATH="/var/www/flash/scripts:$PATH" fi when trying to run as sudo i get: sudo: script: command not found any ideas?

  • ubuntu cobbler server - importing distros

    - by Stu2000
    I setup and fully configured ubuntu-12.04-server machine with cobbler/dhcp running in about 10 minutes (compared to taking over an hour on centos 5.8). I discovered the cobbler import which appears to be useful. Does this remove the need to use a cobbler distro add? whenever I run a cobbler report after a successful import of ubuntu desktop iso: sudo cobbler import --name=Ubuntu --path=/mnt --breed=debian task started: 2012-12-13_163245_import task started (id=Media import, time=Thu Dec 13 16:32:45 2012) Found a debian/ubuntu compatible signature: pool adding distros avoiding symlink loop avoiding symlink loop avoiding symlink loop associating repos associating kickstarts *** TASK COMPLETE *** I just get the following (nothing): distros: ========== profiles: ========== systems: ========== repos: ========== images: ========== mgmtclasses: ========== packages: ========== files: ========== I was rather hoping that I wouldn't have to do the traditional copying of all files in /mnt to a new /distro directory and then perform a cobbler distro add --initrd=/path/to/inird --kernel=/path/to/kernel Maybe I am mistaken about what the import actually does for me.

  • Share on Facebook does not show thumbnail images

    - by matt_tm
    I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site.

  • How can I set access to mounted TrueCrypt volumes, and how can I dismount them on logout?

    I have TrueCrypt setup to mount volumes when I log into my work account. However, when I log out and log in to another account, those volumes are still mounted and available on the other account. How can I set access to those volumes? I don't want all users to be able to access them once they're mounted. (They mounted at /media/volumename - do I just set permissions on the folder "volumename" before mounting?) How can I tell TrueCrypt to dismount them when I log out?

  • 5 Best Practices - Laying the Foundation for WebCenter Projects

    - by Kellsey Ruppel
    Today’s guest post comes from Oracle WebCenter expert John Brunswick. John specializes in enterprise portal and content management solutions and actively contributes to the enterprise software business community and has authored a series of articles about optimal business involvement in portal, business process management and SOA development, examining ways of helping organizations move away from monolithic application development. We’re happy to have John join us today! Maximizing success with Oracle WebCenter portal requires a strategic understanding of Oracle WebCenter capabilities.  The following best practices enable the creation of portal solutions with minimal resource overhead, while offering the greatest flexibility for progressive elaboration. They are inherently project agnostic, enabling a strong foundation for future growth and an expedient return on your investment in the platform.  If you are able to embrace even only a few of these practices, you will materially improve your deployment capability with WebCenter. 1. Segment Duties Around 3Cs - Content, Collaboration and Contextual Data "Agility" is one of the most common business benefits touted by modern web platforms.  It sounds good - who doesn't want to be Agile, right?  How exactly IT organizations go about supplying agility to their business counterparts often lacks definition - hamstrung by ambiguity. Ultimately, businesses want to benefit from reduced development time to deliver a solution to a particular constituent, which is augmented by as much self-service as possible to develop and manage the solution directly. All done in the absence of direct IT involvement. With Oracle WebCenter's depth in the areas of content management, pallet of native collaborative services, enterprise mashup capability and delegated administration, it is very possible to execute on this business vision at a technical level. To realize the benefits of the platform depth we can think of Oracle WebCenter's segmentation of duties along the lines of the 3 Cs - Content, Collaboration and Contextual Data.  All three of which can have their foundations developed by IT, then provisioned to the business on a per role basis. Content – Oracle WebCenter benefits from an extremely mature content repository.  Work flow, audit, notification, office integration and conversion capabilities for documents (HTML & PDF) make this a haven for business users to take control of content within external and internal portals, custom applications and web sites.  When deploying WebCenter portal take time to think of areas in which IT can provide the "harness" for content to reside, then allow the business to manage any content items within the site, using the content foundation to ensure compliance with business rules and process.  This frees IT to work on more mission critical challenges and allows the business to respond in short order to emerging market needs. Collaboration – Native collaborative services and WebCenter spaces are a perfect match for business users who are looking to enable document sharing, discussions and social networking.  The ability to deploy the services is granular and on the basis of roles scoped to given areas of the system - much like the first C “content”.  This enables business analysts to design the roles required and IT to provision with peace of mind that users leveraging the collaborative services are only able to do so in explicitly designated areas of a site. Bottom line - business will not need to wait for IT, but cannot go outside of the scope that has been defined based on their roles. Contextual Data – Collaborative capabilities are most powerful when included within the context of business data.  The ability to supply business users with decision shaping data that they can include in various parts of a portal or portals, just as they would with content items, is one of the most powerful aspects of Oracle WebCenter.  Imagine a discussion about new store selection for a retail chain that re-purposes existing information from business intelligence services about various potential locations and or custom backend systems - presenting it directly in the context of the discussion.  If there are some data sources that are preexisting in your enterprise take a look at how they can be made into discrete offerings within the portal, then scoped to given business user roles for inclusion within collaborative activities. 2. Think Generically, Execute Specifically Constructs.  Anyone who has spent much time around me knows that I am obsessed with this word.  Why? Because Constructs offer immense power - more than APIs, Web Services or other technical capability. Constructs offer organizations the ability to leverage a platform's native characteristics to offer substantial business functionality - without writing code.  This concept becomes more powerful with the additional understanding of the concepts from the platform that an organization learns over time.  Let's take a look at an example of where an Oracle WebCenter construct can substantially reduce the time to get a subscription-based site out the door and into the hands of the end consumer. Imagine a site that allows members to subscribe to specific disciplines to access information and application data around that various discipline.  A space is a collection of secured pages within Oracle WebCenter.  Spaces are not only secured, but also default content stored within it to be scoped automatically to that space. Taking this a step further, Oracle WebCenter’s Activity Stream surfaces events, discussions and other activities that are scoped to the given user on the basis of their space affiliations.  In order to have a portal that would allow users to "subscribe" to information around various disciplines - spaces could be used out of the box to achieve this capability and without using any APIs or low level technical work to achieve this. 3. Make Governance Work for You Imagine driving down the street without the painted lines on the road.  The rules of the road are so ingrained in our minds, we often do not think about the process, but seemingly mundane lane markers are critical enablers. Lane markers allow us to travel at speeds that would be impossible if not for the agreed upon direction of flow. Additionally and more importantly, it allows people to act autonomously - going where they please at any given time. The return on the investment for mobility is high enough for people to buy into globally agreed up governance processes. In Oracle WebCenter we can use similar enablers to lane markers.  Our goal should be to enable the flow of information and provide end users with the ability to arrive at business solutions as needed, not on the basis of cumbersome processes that cannot meet the business needs in a timely fashion. How do we do this? Just as with "Segmentation of Duties" Oracle WebCenter technologies offer the opportunity to compartmentalize various business initiatives from each other within the system due to constructs and security that are available to use within the platform. For instance, when a WebCenter space is created, any content added within that space by default will be secured to that particular space and inherits meta data that is associated with a folder created for the space. Oracle WebCenter content uses meta data to support a broad range of rich ECM functionality and can automatically impart retention, workflow and other policies automatically on the basis of what has been defaulted for that space. Depending on your business needs, this paradigm will also extend to sub sections of a space, offering some interesting possibilities to enable automated management around content. An example may be press releases within a particular area of an extranet that require a five year retention period and need to the reviewed by marketing and legal before release.  The underlying content system will transparently take care of this process on the basis of the above rules, enabling peace of mind over unstructured data - which could otherwise become overwhelming. 4. Make Your First Project Your Second Imagine if Michael Phelps was competing in a swimming championship, but told right before his race that he had to use a brand new stroke.  There is no doubt that Michael is an outstanding swimmer, but chances are that he would like to have some time to get acquainted with the new stroke. New technologies should not be treated any differently.  Before jumping into the deep end it helps to take time to get to know the new approach - even though you may have been swimming thousands of times before. To quickly get a handle on Oracle WebCenter capabilities it can be helpful to deploy a sandbox for the team to use to share project documents, discussions and announcements in an effort to help the actual deployment get under way, while increasing everyone’s knowledge of the platform and its functionality that may be helpful down the road.
