  • NFSv4 - ACLs not working

    - by alex
    I've setup an NFSv4 server (Debian) and client (Ubuntu/Mythbuntu). It seems that uid username mapping is working nicely out-of-the-box (I get correct usernames on ls -l if the usernames match between the two boxes, even if the uids don't), but ACLs are not working. I've installed nfs4-acl-tools and I can read the ACLs correctly on the client, but they don't get applied. What needs to be done for ACLs to work? To clarify; username mapping works for regular permissions. ACLs are applied using uid/gid (I can even set ACLs by uid and they work).

  • Can't install alternate CD from USB?

    - by mattias
    Hi im trying to install ubuntu 12.04 with full hard disk encryption. After downloading and installing the Ubuntu live CD, I learned that truecrypt doesnt support full disk encryption on linux. I also learned that the best way to get "nearly full disk encryption" on ubuntu is by installing it from the alternate install CD. I tried that, but something is wrong with my CD reader/burner so it doesnt boot up when i insert the cd. My thought here was to take the .iso that I downloaded on my unencrypted Ubuntu system, use Unetbootin to make the usb drive. The usb drive used for this is exactly the same brand as one that I know has worked with a previous ubuntu live system on the same computer. I also used unetbootin for that usb, but I created it from windows that time. The usb stick boots up fine and i get through the first couple of steps in the installation process. However, After a while I get a "box" with the following error message "Load Installer components from CD" There was a problem reading data from the CD-ROM. Please make sure it is in the drive. If retrying does not work, you should check the integrity of your CD-ROM. "Failed to copy file from CD-ROM. Retry? " Then I cant get any further. I googled a lot and found this page which seems to tackle this very problem: http://www.dotkam.com/2010/11/29/ins...mage-from-usb/ I tried to do what it said. After pressing TAB, I wrote : cdrom-detect/try-usb=true without quotes because that's what i think is right. When I press TAB, there already is a text saying : /ubnkern initrd=/ubninit vga=788 -- quiet which can be removed. I have tried to both delete the text before the "--" and just inserting cdrom-detect/try-usb=true before it. Any idea of what can be wrong? I would like to do a full system encryption, or as full as it is possible. I dont want to just encrypt my /home folder. Maybe this isn't the easiest way. I use SanDisk usb sticks. I know there is a problem with U3 launcher on some SanDisks, but I never had to remove U3 before from similar disks, and the alternate install does boot up, so I dont think using U3 removal would help me. Any help or indication to an easier way to do this would be appreciated

  • How can I find all hardlinked files on a filesystem?

    - by haimg
    I need to find all hardlinked files on a given filesystem. E.g. get a list of files, each line contains linked pairs, or triplets, etc. I understand more or less how to do it, one needs to create a dictionary keyed by inode for all files/directories on a filesystem, exclude "." and ".." links, and then indodes with more than one name are hardlinks... But I hope that maybe a ready-made solution exists, or someone already wrote such a script.

  • Big-name School for Undergrad Students

    - by itaiferber
    As a soon-to-be graduating high school senior in the U.S., I'm going to be facing a tough decision in a few months: which college should I go to? Will it be worth it to go to Cornell or Stanford or Carnegie Mellon (assuming I get in, of course) to get a big-name computer science degree, internships, and connections with professors, while taking on massive debt; or am I better off going to SUNY Binghamton (probably the best state school in New York) and still get a pretty decent education while saving myself from over a hundred-thousand dollars worth of debt? Yes, I know questions like this has been asked before (namely here and here), but please bear with me because I haven't found an answer that fits my particular situation. I've read the two linked questions above in depth, but they haven't answered what I want to know: Yes, I understand that going to a big-name college can potentially get me connected with some wonderful professors and leaders in the field, but on average, how does that translate financially? I mean, will good connections pay off so well that I'd be easily getting rid of over a hundred-thousand dollars of debt? And how does the fact that I can get a fifth-years master's degree at Carnegie Mellon play into the equation? Will the higher degree right off the bat help me get a better-paying job just out of college, or will the extra year only put me further into debt? Not having to go to graduate school to get a comparable degree will, of course, be a great financial relief, but will getting it so early give it any greater worth? And if I go to SUNY Binghamton, which is far lesser-known than what I've considered (although if there are any alumni out there who want to share their experience, I would greatly appreciate it), would I be closing off doors that would potentially offset my short-term economic gain with long-term benefits? Essentially, is the short-term benefit overweighed by a potential long-term loss? The answers to these questions all tie in to my final college decision (again, permitting I make it to these schools), so I hope that asking the skilled and knowledgeable people of the field will help me make the right choice (if there is such a thing). Also, please note: I'm in a rather peculiar situation where I can't pay for college without taking out a bunch of loans, but will be getting little to no financial aid (likely federal or otherwise). I don't want to elaborate on this too much (so take it at face value), but this is mainly the reason I'm asking the question. Thanks a lot! It means a lot to me.

  • Opening a NTFS partition fails with report: Not authorised

    - by Dugi
    Besides lesser errors on 11.10, I ran into a more annoying one: I cannot access NTFS partitions. No matter whether I use nautilus, dolphin, tux commander or archive manager, always does the same thing, could not mount 'disc name': Not authorised' There were several fixes of problems with access to NTFS partitions, but none of them helped. When I used nautilus in sudo mode, the partition looked empty, although when I booted on windows, there were files. It was reported as a bug somewhere. Can anyone help me?

  • Should comments say WHY the program is doing what it is doing? (opinion on a dictum by the inventor of Forth)

    - by AKE
    The often provocative Chuck Moore (inventor of the Forth language) gave the following advice (paraphrasing): "Use comments sparingly. Programs are self-documenting, with a modicum of help from mnemonics. Comments should say WHAT the program is doing, not HOW." My question: Should comments say WHY the program is doing what it is doing? Update: In addition to the answers below, these two provide additional insight. Beginner's guide to writing comments? http://programmers.stackexchange.com/a/98609/62203

  • What technical test should I give to a job candidate

    - by Romain Braun
    I'm not sure if this is the right stackexhange website, but : I have three candidates coming in tomorrow. One has 15 years of experience in PHP, and the two others have about 1 year of experience in PHP/ frontend development. For the last ones I was thinking about a test where they would have to develop a web app allowing users to manage other users, as in : Display a list of users, display a single user, modify an user, and add extended properties to an user. This way it would feature html, css, js, ajax, php and SQL. Do you think this would be a good test? What test should I give to the first one? He needs something much more difficult, I guess. I'm also listening, if you have any advice/ideas about what makes a good developer, and what I should pay attention to in the guys' codes. I was also considering thinking outside of the box, more algorithm-related, and asked him to make the fastest function to tell if a number is a prime number, because there are a lot of optimizations you can apply to such a function. They have one day to do it.

  • VB alternative/equivalent for development of Windows apps in Ubuntu

    - by Nirmik
    I want to develop a simple form for an Invoice for the user to use on Windows. I learnt how to do it using Visual basic in Windows. It's the simplest way to make a GUI for Windows I suppose. I am going to link it to a database at the backend. I want an alternative or equivalent software that will provide me with similar drag-and-drop feature enabled programing and GUI designing that will help me crate an application that will run on Windows.

  • How to integrate a PHP CMS with paypal so that only users who completed a payment can register and authenticate?

    - by ibiza
    I am currently using a PHP CMS - cmsmadesimple - in order to create a website where services will be sold. I intend to use Paypal 'Buy Now' buttons in order to offer a few packages that will be renewable every 1-month or every 3-months and that grant access to the secure content of the website for a given period of time. Everything is going well so far but I am somewhat at loss for the user registration process as I have a few constraints I would like to use and it would be nice to automate the process if possible. Here are the constraints : User should be able to register to my website and choose a password himself Only users that paid should be able to register Access permissions should be disabled automatically after the service period if the package is not renewed And here is the process which I am thinking of : User clicks 'buy' on my website User is redirected on Paypal and completes the payment The paypal email used to pay should be returned to my server and somehow stored If it is a new email, user needs to register to my website (else if it is a returning customer, the deactivation flag for payment stopped should be removed to give back access) If a user does not renew his subscription, there should be a deactivation flag automatically set to the email used in order to lock access until next payment. Ideally, no human intervention is needed. What is the best way to implement all this? I am a bit at loss. I found this article that explained a few things and even has a nice code snippet, except that I'm not sure where to plug it. Thanks all

  • Design pattern for an automated mechanical test bench

    - by JJS
    Background I have a test fixture with a number of communication/data acquisition devices on it that is used as an end of line test for a product. Because of all the various sensors used in the bench and the need to run the test procedure in near real-time, I'm having a hard time structuring the program to be more friendly to modify later on. For example, a National Instruments USB data acquisition device is used to control an analog output (load) and monitor an analog input (current), a digital scale with a serial data interface measures position, an air pressure gauge with a different serial data interface, and the product is interfaced through a proprietary DLL that handles its own serial communication. The hard part The "real-time" aspect of the program is my biggest tripping point. For example, I need to time how long the product needs to go from position 0 to position 10,000 to the tenth of a second. While it's traveling, I need to ramp up an output of the NI DAQ when it reaches position 6,000 and ramp it down when it reaches position 8,000. This sort of control looks easy from browsing NI's LabVIEW docs but I'm stuck with C# for now. All external communication is done by polling which makes for lots of annoying loops. I've slapped together a loose Producer Consumer model where the Producer thread loops through reading the sensors and sets the outputs. The Consumer thread executes functions containing timed loops that poll the Producer for current data and execute movement commands as required. The UI thread polls both threads for updating some gauges indicating current test progress. Unsure where to start Is there a more appropriate pattern for this type of application? Are there any good resources for writing control loops in software (non-LabVIEW) that interface with external sensors and whatnot?

  • cdrom mounting issues

    This is my very first boot on ubuntu and I noticed the system did not open, pop up anything when I inserted a DVD. Researched a bit about and it seems ubuntu doesn't mount cd drives automatically, is that true or just for my case? I tried some terminal commands and got the cd to mount. Is there a way it will behave like windows, and be there for me when I need it, with no need to play with terminal? thanks for any help. --Mezo
