  • One NIC going to sleep on Centos system

    - by sbleon
    I have two Dell boxes with two ethernet ports a piece. I have a cable directly connecting two of these ports, creating a tiny LAN with 10.3.3.x addresses. The other port on each box is hooked up to a switch and has a DHCP-supplied address to talk to the outside world. I've noticed that when scp'ing large files from one box to the other over the private LAN, the transfers sometimes stall. It appears that any other network activity on either box will cause the transfer to resume. Wake-on-LAN is disabled on all interfaces according to ethtool. What else could be causing these stalled transfers?

  • Cloud Infrastructure has a new standard

    - by macoracle
    I have been working for more than two years now in the DMTF working group tasked with creating a Cloud Management standard. That work has culminated in the release today of the Cloud Infrastructure Management Interface (CIMI) version 1.0 by the DMTF. CIMI is a single interface that a cloud consumer can use to manage their cloud infrastructure in multiple clouds. As CIMI is adopted by the cloud vendors, no more will you need to adapt client code to each of the proprietary interfaces from these multiple vendors. Unlike a de facto standard where typically one vendor has change control over the interface, and everyone else has to reverse engineer the inner workings of it, CIMI is a de jure standard that is under change control of a standards body. One reason the standard took two years to create is that we factored in use cases, requirements and contributed APIs from multiple vendors. These vendors have products shipping today and as a result CIMI has a strong foundation in real world experience. What does CIMI allow? CIMI is both a model for the resources (computing, storage networking) in the cloud as well as a RESTful protocol binding to HTTP. This means that to create a Machine (guest VM) for example, the client creates a “document” that represents the Machine resource and sends it to the server using HTTP. CIMI allows the resources to be encoded in either JavaScript Object Notation (JSON) or the eXentsible Markup Language (XML). CIMI provides a model for the resources that can be mapped to any existing cloud infrastructure offering on the market. There are some features in CIMI that may not be supported by every cloud, but CIMI also supports the discovery of which features are implemented. This means that you can still have a client that works across multiple clouds and is able to take full advantage of the features in each of them. Isn’t it too early for a standard? A key feature of a successful standard is that it allows for compatible extensions to occur within the core framework of the interface itself. CIMI’s feature discovery (through metadata) is used to convey to the client that additional features that may be vendor specific have been implemented. As multiple vendors implement such features, they become candidates to add the future versions of CIMI. Thus innovation can continue in the cloud space without being slowed down by a lowest common denominator type of specification. Since CIMI was developed in the open by dozens of stakeholders who are already implementing infrastructure clouds, I expect to CIMI being adopted by these same companies and others over the next year or two. Cloud Customers who can see the benefit of this standard should start to ask their cloud vendors to show a CIMI implementation in their roadmap.  For more information on CIMI and the DMTF's other cloud efforts, go to: http://dmtf.org/cloud

  • You may be tempted by IaaS, but you should PaaS on that or your database cloud journey will be a short one

    - by B R Clouse
    Before we examine Consolidation, the next step in the journey to cloud, let's take a short detour to address a critical choice you will face at the outset of your journey: whether to deploy your databases in virtual machines or not. A common misconception we've encountered is the belief that moving to cloud computing can be accomplished by simply hosting one's current operating environment as-is within virtual machines, and then stacking those VMs together in a consolidated environment.  This solution is often described as "Infrastructure as a Service" (IaaS) because the building block for deployments is a VM, which behaves like a full complement of infrastructure.  This approach is easy to understand and may feel like a good first step, but it won't take your databases very far in the journey to cloud computing.  In fact, if you follow the IaaS fork in the road, your journey will end quickly, without realizing the full benefits of cloud computing.  The better option to is to rationalize the deployment stack so that VMs are needed only for exceptional cases.  By settling on a standard operating system and patch level, you create an infrastructure that potentially all of your databases can share.  Now, the building block will be database instances or possibly schemas within databases.  These components are the platforms on which you will deploy workloads, hence this is known as "Platform as a Service" (PaaS). PaaS opens the door to higher degrees of consolidation than IaaS, because with PaaS you will not need to accommodate the footprint (operating system, hypervisor, processes, ...) that each VM brings with it.  You will also reduce your maintenance overheard if you move forward without the VMs and their O/Ses to patch and monitor.  So while IaaS simply shuffles complex and varied environments into VMs,  PaaS actually reduces complexity by rationalizing to the small possible set of components.  Now we're ready to look at the consolidation options that PaaS provides -- in our next blog posting.

  • What are the minimum required modules to run WordPress

    - by Mister IT Guru
    Recently a 'consultant' came in to talk to bean counters at my place of employment, with regards to being more efficient with our IT infrastructure. They suggested to be more efficient we should only load the Apache modules that are required on our web servers. (This is just 1 of 1Ks of suggestions). The Bean Counters are very excited, and prepared for me to spend the time to investigate this avenue of cost cutting. I don't mind this mundane exercise, I see it as a learning experience! I guess this leads me to the actual question: How can I determine the minimum required apache modules for a PHP based application without actually going through the code, or plain old trial and error?

  • How can one associate a 3ware controller with the corresponding /dev/tw?? device?

    - by barbaz
    I have a few 3ware RAID controllers installed in a system. Is there any way to figure out the mapping between the following identifiers, each describing in a way the very same RAID controller? The tw_cli reported controller id (e.g. c0,c1,c2,...) The corresponding device nodes that allow smartctl access via the 3ware driver (e.g. /dev/twa0, /dev/twa1, /dev/twl0) The block device presented to the system representing a RAID unit (/dev/sda, /dev/sdb,...)

  • killing all instances of chrome on the command line?

    - by Fedor
    In some cases killing a single tab/process doesn't do it and I need to close Chrome entirely. Since Chrome has multiple processes, how can I close all of them at once? I know that... pgrep chrome returns all the pids, can someone tell me a trick that would allow me to close all of them by feeding them to another command or merging them to a csv or something?

  • After installing Ubuntu how do I get rid of unity and go back to gnome?

    - by aseq
    After I have installed the newest Ubuntu LTS release (12.04, still in beta though) I am greeted with an unfamiliar and difficult to use desktop environment. I believe it is called unity. However I have used gnome for a decade and a half and I would not like to move to this new and (for me) unusable desktop environment. What is a quick and easy way to remove (most) of unity and bring back gnome, as well as configure my display manager to load gnome by default with the environment as close as possible to the way it was before?

  • How to determine if a file has been backed up?

    - by Console
    I try to consolidate old drives to new ones of larger capacity. Sometimes files have been renamed, but are otherwise identical. Sometimes an old directory has just a few more files in it than a newer directory with the same name. Sometimes a file has the same name but the size differs. So I often find myself asking the question: Are there any files on this old drive or directory that I haven't already copied to the new drive? I just want to know that I have the files, I don't want to try and sync stuff automatically (Syncing tools tend to just sync, creating duplicate folder structures and other problems, so I prefer to do it by hand). Basically, if an old drive has a file called "foo.bar" ten directories deep, and my new big drive has an identical file called "oldstuff.zip" in the root, I just want a "yes you have it" or "no, unique files exist". Is there a free tool, a script or a quick and easy method (Mac/Unix or Windows) to get the answer?

  • How can I turn off font-antialiasing only for gnome-terminal, but not for other applications?

    - by dan
    I'm running GNOME (gnome-session under xmonad). I want to turn off antialiasing (i.e. use monochrome mode) for fonts in gnome-terminal. But I want to retain antialiasing for other applications, like Firefox. Is this possible? Antialiasing is great and almost necessary for using Firefox or Chrome. But it makes the fonts in gnome-terminal blurry at sizes around 12 or smaller. Otherwise, I'll just have to use xterm, which seems not to anti-alias its fonts under any circumstances.

  • The Lease Standard Train is Back on Track

    - by Theresa Hickman
    As I was walking to the elevator, I ran into Seamus Moran, our resident accounting expert. Me: “Hi Seamus, where have you been? You don’t write, you don’t call, and you don’t send me flowers. I’ve been hearing more and more about the Lease Accounting topic. It looks like Congress is weighing in on it too and putting heat on FASB. According to a recent article in Reuters  “representatives Brad Sherman, a Democrat, and Republican John Campbell, have written to the U.S. Financial Accounting Standards Board warning of dire economic fallout from a plan to have companies put leases on their balance sheets." Here’s what Seamus had to say: Yes, but there have been some recent developments. The FASB and IASB cleared a logjam, resolved a final “content of the standard” issue, and articulated a way to move forward on Leases last Wednesday.  It looks like the Lease Standard Train is back on track.   We’ve just had a briefing from PwC. The Lease timeline now looks like this: Now to June 2012: The staff will write up the decisions June 2012: Boards will meet on “logistical” issues (glossed over) Oct, Nov, most likely December 2012: A New Lease Exposure Draft will be crafted January – April 2013: Public Comment period begins April to September 2013: Everyone to digest the comments and draft the final standard End of 2013 (Probably more like Early 2014): Publish the new Lease Accounting Standards 2015: Retroactive reporting 2017: New standard is effective It seems that leases under one year will be treated as “rent expense”. If it doesn’t cross two (annual) balance sheets, it doesn’t really matter. This is good news in terms of clarity, resolution, and moving forward on one of the last remaining items to converge the IFRS and U.S. GAAP standards. There are ambiguities, issues, concerns, et cetera, of course, and there are bright lines (“rules”) that bother the “no rules, please” people and ambiguities (“judgments”) that bother the “clarity, please” people, but at least the train isn’t falling off the tracks.

  • How to start a service at boot time in ubuntu 12.04, run as a different user?

    - by Alex
    I have a server ClueReleaseManager which I have installed on a Ubuntu 12.04 system from a separate user (named pypi), and I want to be able to start this server at startup. I already have tried to create a simple bash script with some commands (login as user pypi, use a virtual python environment, start the server), but this does not work properly. Either the terminal crashes or when I try to ask the status of the service it is started and I am logged in as user pypi ...? So, here the question: What are the steps to take to make sure the ClueReleaseManager service properly starts up on boot time, and which I can control (start/stop/..) during runtime, while the service is running from a user pypi? Additional information and constraints: I want to do this as simple as possible Without any other packages/programs to be installed I am not familiar with the Ubuntu 12.04 init structure All the information I found on the web is very sparse, confusing, incorrect or does not apply to my case of running a service as a different user from root.

  • installing latest apache on centos

    - by fivelitresofsoda
    hi, I'm trying to install the newest version of apache on my centos server. I did the following: Download $ wget http://httpd.apache.org/path/to/latest/version/ Extract $ gzip -d httpd-2_0_NN.tar.gz $ tar xvf httpd-2_0_NN.tar Configure $ ./configure Compile $ make Install $ make install Test $ PREFIX/bin/apachectl start And that all worked except the last step, when i type apachectl start it says 'command not found'. I ran this command from /usr/local/apache2/bin/ where it is installed but no cigar. Any idea what i am doing wrong? Thanks.

  • How to Hashtag (Without Being #Annoying)

    - by Mike Stiles
    The right tool in the wrong hands can be a dangerous thing. Giving a chimpanzee a chain saw would not be a pretty picture. And putting Twitter hashtags in the hands of social marketers who were never really sure how to use them can be equally unattractive. Boiled down, hashtags are for search and organization of tweets. A notch up from that, they can also be used as part of a marketing strategy. In terms of search, if you’re in the organic apple business, you want anyone who searches “organic” on Twitter to see your posts about your apples. It’s keyword tactics not unlike web site keyword search tactics. So get a clear idea of what keywords are relevant for your tweet. It’s reasonable to include #organic in your tweet. Is it fatal if you don’t hashtag the word? It depends on the person searching. If they search “organic,” your tweet’s going to come up even if you didn’t put the hashtag in front of it. If the searcher enters “#organic,” your tweet needs the hashtag. Err on the side of caution and hashtag it so it comes up no matter how the searcher enters it. You’ll also want to hashtag it for the second big reason people hashtag, organization. You can follow a hashtag. So can the rest of the Twitterverse. If you’re that into organic munchies, you can set up a stream populated only with tweets hashtagged #organic. If you’ve established a hashtag for your brand, like #nobugsprayapples, you (and everyone else) can watch what people are tweeting about your company. So what kind of hashtags should you include? They should be directly related to the core message of your tweet. Ancillary or very loosely-related hashtags = annoying. Hashtagging your brand makes sense. Hashtagging your core area of interest makes sense. Creating a specific event or campaign hashtag you want others to include and spread makes sense (the burden is on you to promote it and get it going). Hashtagging nearly every word in the tweet is highly annoying. Far and away, the majority of hashtagged words in such tweets have no relevance, are not terms that would be searched, and are not terms needed for categorization. It looks desperate and spammy. Two is fine. One is better. And it is possible to tweet with --gasp-- no hashtags! Make your hashtags as short as you can. In fact, if your brand’s name really is #nobugsprayapples, you’re burning up valuable, limited characters and risking the inability of others to retweet with added comments. Also try to narrow your topic hashtag down. You’ll find a lot of relevant users with #organic, but a lot of totally uninterested users with #food. Just as you can join online forums and gain credibility and a reputation by contributing regularly to that forum, you can follow hashtagged topics and gain the same kind of credibility in your area of expertise. Don’t just parachute in for the occasional marketing message. And if you’re constantly retweeting one particular person, stop it. It’s kissing up and it’s obvious. Which brings us to the king of hashtag annoyances, “hashjacking.” This is when you see what terms are hot and include them in your marketing tweet as a hashtag, even though it’s unrelated to your content. Justify it all you want, but #justinbieber has nothing to do with your organic apples. Equally annoying, piggybacking on a popular event’s hashtag to tweet something not connected to the event. You’re only fostering ill will and mistrust toward your account from the people you’ve tricked into seeing your tweet. Lastly, don’t @ mention people just to make sure they see your tweet. If the tweet’s not for them or about them, it’s spammy. What I haven’t covered is use of the hashtag for comedy’s sake. You’ll see this a lot and is a matter of personal taste. No one will search these hashtagged terms or need to categorize then, they’re just there for self-expression and laughs. Twitter is, after all, supposed to be fun.  What are some of your biggest Twitter pet peeves? #blogsovernow

  • Ubuntu12.04 - launched applications, not staying in same desktop

    - by Anders Metnik
    My question is why a launched application, if it has loading time like netbeans, eclipse jdeveloper etc. If i go to desktop3 and launch an application and then go to desktop 2 while I wait, then when it has loaded the application will launch in desktop2. Is there anyway to change this? I find it highly annoying since i on startup would like to launch 3-4 big applications, leave my computer while loadingf, and then return. But i cant leave since i have to launch them sequential instead of simultaneous... Help please :-)

  • How to set TV-out options under Linux of an Geforce 9600 GT video card

    - by polemon
    I'm using the TV-out connector of my Geforce 9600 GT to connect it to an old TV set. It's obviously in Composite mode, the other two cables of Component video are dead, only Pb/VIDEO labeled one gives me a signal. The picture appears black/white on the TV, I presume it's because the video card gives me an NTSC signal, but it's a PAL tv set. How do I change the TV-out from NTSC to PAL? My Component to SCART adapter hasn't arrived yet, but I think I should be able to set manually, whether the signal should be Composite or Component. How do I switch modes of the TV-out, between Component and Composite? I'm running Linux, so it's probably some settings I need to make in xorg.conf. Edit: I got this far: I need to set in the "Device" section of my xorg.conf: Option "TVStandard" "PAL-B" Option "TVOutFormat" "COMPOSITE" The whole section looks like this now: Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 9600 GT" Option "AddARGBGLXVisuals" "True" Option "TVStandard" "PAL-B" Option "TVOutFormat" "COMPOSITE" EndSection How can I list all available settings for "TVStandard" and "TVOutFormat"?

  • Change permission to /proc/net/ip_conntrack on Ubuntu server 9.10

    - by bjarkef
    Hi I have a script that needs to extract certain information form the /proc/net/ip_conntrack file once in a while. I do not wish to run this script as the root user. Default permissions for the file is: $ ls -lah /proc/net/ip_conntrack -r--r----- 1 root root 0 2010-03-28 12:18 /proc/net/ip_conntrack I can change it with: sudo chmod o+r /proc/net/ip_conntrack But that does not stick after a reboot. Is there some configuration file for file-permissions in the /proc directory in Ubuntu Server 9.10? Or do I just have to stick a chmod line in some startup script?
