  • OpenBSD : NETSEC certainement impliqué dans une tentative d'insertion de backdoors, selon le responsable de l'OS

    OpenBSD : NETSEC certainement impliqué dans la tentative d'insertion de backdoors Sur demande du FBI, mais toujours aucune trace avérée de porte dérobée Mise à jour du 23/12/2010 Les investigations avancent sur les allégations émises la semaine dernière quant à une éventuelle insertion de portes dérobées (backdoors) dans le système OpenBSD (lire ci-avant).

  • Screen split oddly when OS is installed from a Live CD

    - by Brian
    Never used Linux before but I decided I want to start somewhere and Ubuntu seemed like the right place to start. I burned the 64bit version ISO onto a CD and installed it onto a fresh new hard drive I have. The Live CD works and the Live Distro thing works great. However when I attempt to install it, the screen splits oddly in a way where part of the right is on the left. Furthermore, after attempting to log in, the GUI doesn't show up and the computer would freeze and stay that way. However you can still move the cursor. I can't really get in or do anything (possibly because I don't know how) and tinker around since I am not too tech savvy. But I can follow instructions. Graphics Card Radeon hd 6670 I just tried the install with windows thing. There was the exact same problem.

  • Boot path not found, cannot start OS

    - by Dustin
    My desktop is 12.04 64bit, and it cannot boot from the hard drive anymore. When I attempt to it just is stuck on a blank screen with an blinking dash, and nothing happens. I checked with the bios trouble shoot for problems and it said that no boot path could be found. I do not know why this is happening, but need to fix it because it used to boot up normally. What I need to know is how to fix it. I can boot into a live DVD. Also, there were a few boots I would attempt to boot into a live USB, then it would boot to the hard drive, but that does not work any more. So with the live DVD (it is an 10.04 LTS 32bit), is there any means to correct the boot path from the live DVD? Thank you for your time and answers.

  • Destroy guest OS using php

    - by Alee
    I am using libvirt-php to manage my virtual machines, and I need to shutdown/destroy domU. For this I used the following php script: < ? php $conn=libvirt_connect("xen:///"); $name=libvirt_domain_lookup_by_id($conn,4); $dest=libvirt_domain_destroy($name); echo $dest; ? When I run this on xampp server i get the following output: Warning: libvirt_domain_destroy() [function.libvirt-domain-destroy]: operation virDomainDestroy forbidden for read only access in /opt/lampp/htdocs/xampp/byname.php on line 5.

  • Developing games using virtualization on macOS (or Linux) [on hold]

    - by zpinner
    From what I've seen, most of the gamedev tools and engines (that could generate cross platform games) are not supported on Mac. Havok/Project Anarchy, UDK, GameMaker, e.g. . Basically, the only options I found are: Unity3d and monogame + xamarin. Unity is nice and I've been playing with it for some time, but the free version is quite limited when we're talking about shaders, that made me consider that as an indie developer, I might want more freedom to experiment new things, without paying the expensive unity license. I didn't try monogame + xamarin yet, and altough XNA is a very nice game framework, I'd like to have more freedom to experiment and finish a game first before paying for the IDE, which is not possible with the current Xamarin business model. That leaves me with the thought that I must go back to windows, which I'd preferably do it partially, if it's possible. Using BootCamp is something that I'd like to avoid, since it's a pain to reboot when changing OS and that would probably force me to become a 100% windows user. Is there anyone actually developing a game using virtualization solutions like parallels or vmwareFusion? How was your experience?

  • Connecting my iPhone to iTunes causes my Acer laptop to crash

    - by Paul Sheldrake
    Hello I have an Acer Travelmate 8200 laptop and whenever I connect my Iphone to it, it crashes with the BSOD(Blue Screen Of Death). I have figured out that if I delete all the pictures in my phone I can get it to connect but that is not a ideal long term solution. I also read that it may be a conflict with the built in web-cam I have but I've upgraded the driver and I still get the crashing problem. Any suggestions would be appreciated! Thanks Paul! edit: Here is the BSOD message I get

  • print jobs are held until the VirtualBox guest OS is reboot

    - by broiyan
    Here is the setup: VirtualBox 4.1.20 (which the Help window describes as 4.1.12_Ubuntu) Extension Pack 4.1.20 (for USB support) Windows 7 Home Premium as a guest operating system on VirtualBox Ubuntu 12.04 with dist-upgrade's to September 2012 as the host operating system. Fuji Xerox DocuPrint P205b, which I believe is a GDI printer, connected via USB. The problem is that often print jobs will sit in the print queue and nothing comes out of the printer. The printer status for the first item in the queue will be Printing even though nothing happens. Then upon rebooting Windows, the print jobs get printed, seemingly simultaneous to the rebooting process; that is as Windows reloads. One way to avoid this problem is to reboot Windows with the printer cable attached, and then submit the print jobs. The print jobs get printed in a timely manner. Perhaps VirtualBox has a problem with USB being plug-n-play and hot pluggable. It's not convenient to have the printer plugged in when Windows boots because: One, this is a laptop, and Two, I may be boot Windows for a purpose other than printing and not anticipate needing to print. Are there any recommendable fixes for this problem?

  • Dual Boot: access Mac OS HD folders from Ubuntu

    - by dresde
    I did it!!! I'm right now writting from Ubuntu 11.10 installed in my MacBook Pro using Dual Boot!!! THe only thing is, how can I now access my Mac folders? From Ubuntu if I try to open Music, Documents or any of those folders related to the Mac user I get the following: [The folder contents could not be displayed. You do not have the permissions necessary to view the contents of "Music"] I can access them if I run Nautilus from root (gksudo nautilus), but I would like to just be able to browse those folders. Thanks!

  • Impossible to boot Ubuntu on a USB stick (OS X Montain Lion)

    - by user109513
    I know this has been discussed over and over but I still cannot run Ubuntu on a USB stick. Here's the step I followed: 1. I downloaded Ubuntu 12.10 (ubuntu-12.10-desktop-i386.iso) from http://www.ubuntu.com/download/desktop which I renamed 'ubuntu.iso'. I bought my Mac mid-2010, it has an Intel processor. 2. I formated my 16GB USB stick with HFS+ File System following this tutorial: http://www.switchingtomac.com/tutorials/how-to-format-a-drive-or-partition-with-the-hfs-file-system 3. I opened a terminal and typed: hdiutil convert -format UDRW -o ~/Downloads/ubuntu.img ~/Downloads/ubuntu.iso It created ubuntu.iso.dmg 4. I ran 'diskutil list' and identified the device node assigned to the USB. 5. I unmounted it: diskutil unmountDisk /dev/disk2 6. Then, I entered the command: sudo dd if=~/Downloads/ubuntu.img.dmg of=/dev/rdisk2 bs=1m. It seemed to work. A Mac message poped up saying that the system doesn't recognized the disk, I pressed 'ignore'. 7. I ejected the USB using diskutil eject /dev/disk2, then removed the USB. 8. I rebooted the computer, plugged the USB key, pressed ALT.I could see my Macintosh partition and my Windows partition, but couldn't see my USB stick. Any help will be very appreciated :) Victor

  • Setting up an Ubuntu 9.10 chroot for Android OS builds

    <b>Spencer Herzberg Blog: </b>"So the goal of this post will be to install a 32-bit chroot of 9.10 in my fresh install of 10.04 as 9.10 is easier to build and test Cyanogen's custom Android rom. I have modified some guides from here and here. I have also elected to use schroot as it allows for easy chroot access."

  • Amazon EC2 Instance - m1.medium Ubuntu 12.04 - Started to crash three days ago

    - by Joy
    The environment: Amazon EC2 Instance - m1.medium Ubuntu 12.04 Apache 2.2.22 - Running a Drupal Site Using MySQL DB Server RAM info: ~$ free -gt total used free shared buffers cached Mem: 3 1 2 0 0 0 -/+ buffers/cache: 0 2 Swap: 0 0 0 Total: 3 1 2 Hard drive info: Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.9G 4.7G 2.9G 62% / udev 1.9G 8.0K 1.9G 1% /dev tmpfs 751M 180K 750M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1.9G 0 1.9G 0% /run/shm /dev/xvdb 394G 199M 374G 1% /mnt The problem About two days ago the site started failing becaue the MySQL server was shut down by Apache with the following message: kernel: [2963685.664359] [31716] 106 31716 226946 22748 0 0 0 mysqld kernel: [2963685.664730] Out of memory: Kill process 31716 (mysqld) score 23 or sacrifice child kernel: [2963685.664764] Killed process 31716 (mysqld) total-vm:907784kB, anon-rss:90992kB, file-rss:0kB kernel: [2963686.153608] init: mysql main process (31716) killed by KILL signal kernel: [2963686.169294] init: mysql main process ended, respawning That states that the VM was occupying 0.9GB, but my Ram has 2GB free, so 1GB was still left free. I understand that in Linux applications can allocate more memory than physically available. I don't know if this is the problme, it's the first time that it has started to happen. Obviously, the MySQL server tries to restart, but there's no memory for it apparently and it won't restart. Here is its error log: Plugin 'FEDERATED' is disabled. The InnoDB memory heap is disabled Mutexes and rw_locks use GCC atomic builtins Compressed tables use zlib 1.2.3.4 Initializing buffer pool, size = 128.0M InnoDB: mmap(137363456 bytes) failed; errno 12 Completed initialization of buffer pool Fatal error: cannot allocate memory for the buffer pool Plugin 'InnoDB' init function returned error. Plugin 'InnoDB' registration as a STORAGE ENGINE failed. Unknown/unsupported storage engine: InnoDB [ERROR] Aborting [Note] /usr/sbin/mysqld: Shutdown complete I simply restarted the Mysql service. About two hours later it happened again. I restarted it. Then it happened again 9 hours later. So then I thought of the MaxClients parameter of apache.conf, so I went to check it out. It was set at 150. I decided to drop it down to 60. As so: <IfModule mpm_prefork_module> ... MaxClients 60 </IfModule> <IfModule mpm_worker_module> ... MaxClients 60 </IfModule> <IfModule mpm_event_module> ... MaxClients 60 </IfModule> Once I did that, I had the apache2 service restart and it all went smoothly for 3/4 of a day. Since at night the MySQL service shut down once again, but this time it wasn't killed by the Apache2 service. Instead it called the OOM-Killer with the following message: kernel: [3104680.005312] mysqld invoked oom-killer: gfp_mask=0x201da, order=0, oom_adj=0, oom_score_adj=0 kernel: [3104680.005351] [<ffffffff81119795>] oom_kill_process+0x85/0xb0 kernel: [3104680.548860] init: mysql main process (30821) killed by KILL signal Now I'm out of ideas. Some articles state that the ideal thing to do is change the kernel behaviour with the following (include it to the file /etc/sysctl.conf ) vm.overcommit_memory = 2 vm.overcommit_ratio = 80 So no overcommits will take place. I'm wondering if this is the way to go? Keep in mind I'm no server administrator, I have basic knowldege. Thanks a bunch in advance.

  • Troubleshooting a crash with Windows 7

    - by AngryHacker
    I have a folder with several thousand videos (All .MPG extensions). When I open the folder with these videos, it shows up fine, but as I start scrolling down, it crashes the Windows Explorer. In the Event Viewer, I see this: Faulting application name: Explorer.EXE, version: 6.1.7600.16450, time stamp: 0x4aebab8d Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b802 Exception code: 0xc0000374 Fault offset: 0x00000000000c6df2 Faulting process id: 0x954 Faulting application start time: 0x01cbb1b71edf3b51 Faulting application path: C:\Windows\Explorer.EXE Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: ee987372-1dc4-11e0-8e06-406186ea9135 I suspect that one of the videos has bad metadata. I removed the Length column and it was still crashing. I then removed the Date column and the problem disappeared. How do I go about troubleshooting this problem or at least identifying the file that's causing the issue.

  • is it possible for windows viruses when downloaded through ubuntu affect my windows os

    - by fr33c0untry
    I know that Ubuntu is immune to virus so there is no question of it getting infected while browsing the net.however i frequently transfer files from my pendrive (which i get from other virus infested computers) to my own laptop and save it on the data drive which is shared by both windows and ubuntu.i would like to know if there is a chance for windows viruses which might get saved and then infect it whenever i switch to windows later on.its ironic that i scan my pendrive using avast on windows and then save all my files to my hard drive to keep my laptop free from virus eventhough i have ubuntu.can anyone suggest an alternative.thanks in advance.

  • Transition from 2D to 3D Game development [closed]

    - by jakebird451
    I have been working in the 2D world for a long time from manual blitting in windows to SDL to Python (pygame, pyopengl) and a bunch in between. Needless to say I have been programming for a while. So a while ago I started to program in OpenGL via C++ on my Mac. I then got a little intricate with my work after a while (3D models with skeleton structure and terrain development). After a long time of tinkering, I stopped due to the heavy work just to yield a low level understanding of how OpenGL works. Still interested in Graphics and Game Development I went on a search for a stable game engine with some features to grow on. Licence Requirement: Anything other than GPL (LGPL will do) OS Requirement: Mac & Windows Shader: GLSL or CG (GLSL preferred due to experience) Models: Any model structure with rigging (bone) support & animation I am looking at http://www.ogre3d.org/ currently and am starting to meddle around with some examples. However I am a little reluctant to spend a lot of time on it only to yield another dead end. So instead of falling down a spiraling black pit, I am posting my question to you guys to lead me in the right direction based on my requirements. How was your experience with the engine you recommend? Is it well documented? Does it have well documented examples? Any library requirements (Boost, libpng, etc)?
