  • 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. If someone could elaborate on what the import is actually for please do.

  • Where did my free space go?

    - by Ari B. Friedman
    I have a storage drive (2TB) and an OS drive (90GB SSD). I've run out of space on the OS drive: /$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sdb1 72G 72G 0 100% / udev 5.9G 12K 5.9G 1% /dev tmpfs 2.4G 1.2M 2.4G 1% /run none 5.0M 0 5.0M 0% /run/lock none 5.9G 428K 5.9G 1% /run/shm /dev/sda1 1.9T 639G 1.2T 37% /media/StorageDrive So be it. But when I attempt to figure out where the space has gone, I cannot find it anything remotely approaching the capacity of the drive: /$ sudo du -h -d 1 du: cannot access `./media/StorageDrive/home/ari/.gvfs': Permission denied 675G ./media 2.3G ./var 0 ./proc 7.0M ./tmp 27M ./boot 4.0K ./lib64 12K ./dev 44M ./home 16K ./lost+found 8.0M ./sbin 223M ./lib 4.0K ./selinux 1.4M ./run 140K ./root 8.8M ./bin 4.0K ./mnt 38M ./etc 8.0K ./srv 4.8G ./usr 65M ./opt 0 ./sys 682G . Note the difference between the total (682G) and the mounted drives in /media (675G) is only about 9G. How are 72G being used? Where is this dark matter hiding?

  • Ubuntu cannot boot after kernel upgrade

    - by andrey
    Today I have upgraded the Linux kernel (using the Update Manager), from 3.0.0.16-generic to 3.0.0.17-generic. However, after this update, Ubuntu 11.10 cannot boot anymore. I see a strange message which says "initclt: event failed". And if I press [Ctrl]+[Alt]+[F1] it still allows me to log into the text mode. But if I type sudo lightdm, I cannot log into the graphical mode. However, if I choose to boot an older kernel from the GRUB, Ubuntu boots correctly. What should I do, in order to be able to boot the system using the new kernel?

  • Unable to change the launcher icon size

    - by takeshin
    After upgrading to 11.10 I can't change the launcher icon size to smaller. I've tried to change it using ccsm, like described in How can I configure Unity, but the changes take no effects (restarted, tried sudo - still big icons). In the previous version of Ubuntu this solution worked. How can I change the icon size? (BTW, how can I know which Unity (2D vd 3D) I'm running and switch between?). Edit: Looks like I'm using Unity 2D and have some problems with graphics: me@my-laptop ~ $ /usr/lib/nux/unity_support_test -p Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0".

  • Proper fstab entry to mount a samba share in 12.04

    - by JPbuntu
    I am a little confused on the proper fstab entry for a samba share in Ubuntu 12.04 I can get the drive to mount manually by using: sudo mount -t cifs //192.168.2.2/raid_drive /mnt/homeserver -o username=jon,password=password So I tried putting this in fstab: //192.168.2.2/raid_drive /mnt/homeserver cifs username=jon,password=password,iocharset=utf8,mode=0777,dir_mode=07??77 0 0 Which gives me this error in syslog: kernel: [ 2217.925354] CIFS: Unknown mount option mode kernel: [ 2217.936345] CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel release 3.3 This guide says to use smbfs although I believe smbfs is deprecated? What is a common fstab configuration for a samba share in Ubuntu 12.04? EDIT: Using the accepted answer below I was initially getting this error message (from dmesg): [ 45.520883] CIFS VFS: Error connecting to socket. Aborting operation [ 45.520990] CIFS VFS: cifs_mount failed w/return code = -115 although it turns out this was due to network connectivity issues, and not related to improper fstab entry.

  • Need Help Unable to Mount Location

    - by Don't ASk Ubun
    I am not able to start Windows and am using a DVD copy of Ubuntu to start up. I see my 750 GB Hard Disk, but if I click it i get this error: Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. After googling for a while I think I need to do sudo apt-get install ntfsprogs but when I try that: E: Package 'ntfsprogs' has no installation candidate My problem is a lot like this thread

  • How can I recursively change the permissions of files and directories?

    - by Nikhil
    I have ubuntu installed on my local computer with apache / php / mysql. I now have a directory at /var/www - inside which I have several of my ongoing projects. I also work with opensource ( drupal, magento, sugarcrm ). The problem I am facing is changing file permission with terminal. Sometime I need to change the permission of entire folder and its subsequent sub-folders and files. I have to individually change using sudo chmod 777 foldername How can I do this recursively. Also why do I have to always do it 777, I tried 755 for folders and 644 for files, but that won't work.

  • Only recognizes one of multiple partitions on SD card

    - by Jay Ngo
    Hello everybody, I split my sd card into 2 partitions. When i use usb-card-reader to read my sd card, only the one partition shows up on the screen, the other doesn't. I have run the command "sudo fdisk -l" and the result is the same, only one partition is recognized. But i do believe both partitions of my sd card work fine, because i still can boot my single-board computer with that sd card and run some programms, which are inside that unreadable partition. How can i access both partitions of my sd card? Does anyone know how to solve this kind of problem? I really appreciate your help.

  • How did Ubuntu know my WPA Key?

    - by nebukadnezzar
    I've recently moved my /home to another computer (keeping all configuration files), with a fresh installation of Ubuntu 10.10. After Installation I've installed wicd and ndiswrapper, to get my Internet Connection up and running. However, after changing /etc/network/interfaces from auto lo iface lo inet loopback To auto wlan0 iface wlan0 inet dhcp and running sudo /etc/init.d/networking restart to get wlan0 set up, wicd just suddenly connected... to my modem. Without supplying any information about the modem whatsoever. Of course wicd creates a local directory at ~/.wicd/, but that directory is empty, and the temporary global configuration at /var/lib/wicd/configurations/ didn't exist due to fresh installation of ubuntu. So what's the deal? Where did wicd get the ESSID and the WPA Key? There hasn't been any activity in this question, but it's still open (and even worth some rep)!

  • Adobe-Flash-plugin freezes when skipping ahead

    - by piedro
    I am using Firefox 7 and the new official Adobe Flash 64-bit plugin from the Ubuntu Partner repository. It's the adobe-flash package. It works nicely on the first look but when I try to skip ahead in any YouTube video (by clicking on the video progress bar) sound will go on but the video simply freezes at the position it was just before skipping. This is really annoying because I really don't want to watch every video full length. Now maybe there's cleanup work to do? I removed every Flash-related package from the package manager. Maybe it's Firefox? I couldn't find any hint. Maybe it's the video manager (display manager)? I am using KDE on an Ubuntu Natty install. I also enabled hardware acceleration with libdvpau1: sudo bash -c "echo 'EnableLinuxHWVideoDecode=1' >> /etc/adobe/mms.cfg" (this seems to have no effect at all ...) Ubuntu Natty 64-bit, Firefox 7, Flash 11.01 )

  • ATI Catalyst doesn't retain changes after reboot when setting extended display

    - by rfc1484
    I have Ubuntu 11.10 and I'm trying to set up extended display for my two displays. I have an AMD 6870. fglrx and fglrx-updates are installed. When I launch amdcccle trough the terminal (using sudo), I select in tab "Multi-Display" the option "Multi-display Desktop with Display(s)". Then it says for changes to be done I have to reboot my computer. Being a good an obedient lad I do just that, but after rebooting the displays are still in the same "clone" option as before in the Catalyst Control Center and no changes are made. Any suggestions?

  • Rhythmbox plugin radio-browser crashes

    - by Marco
    I have just installed the plugins package from fossfreedom repository on my Rhythmbox 2.96 running on 12.04 (64 bit). The radio-browser plugin crashes Rhythmbox after a few seconds of playing. When I restarted Rhythmbox after the crash, the plugin was marked as "error" and it is impossible to reinstall it. I've then manually removed (sudo apt-get remove ...) and reinstalled it but still I can't enable it. Unfortunately, radio-browser was the reason for me to install the plugin package, and I can't use it... Help please?

  • How do I restore the privacy pane of the system settings?

    - by Sparhawk
    Checking out screenshots of the system settings in Ubuntu 12.10, it seems that I am missing a few. When I open up my settings, I cannot see Privacy, Backup, and Management Service. Also, nothing comes up when I search the Dash for these words. In a previous edition of Ubuntu, I purged Ubuntu One (with sudo apt-get purge ubuntuone-client python-ubuntuone-storage* ubuntuone-couch ubuntuone-installer) and appropriately, I cannot see the Ubuntu One icon. I've also previously purged unity-lens-music Perhaps I purged some metapackage that removed the others? In any case, how do I restore the privacy pane (as well as the other icons)? Also, any suggestions for what I did to remove the packages in the first place (and hence how to avoid this problem in the future)?

  • Ubuntu GUI crash when LightDM enters, unable to login

    - by Cesar
    This issue happened spounteniously, i don´t know what could have cause it as i wasn´t using the PC when it happened. I ruled out any messing around with the setting as the user doesn´t know how to enter the BIOS, doesn´t have the sudo password and was only using firefox and libreoffice when it happened. After the plymouth sequence i get this error. https://www.dropbox.com/s/uf1xdkqkw9alvcu/IMAG0252.jpg And this option: https://www.dropbox.com/s/tpivkgjkx2spa3v/IMAG0253.jpg I follow each option and nothing happens after that. The issue persist after rebooting. I choose the other options to see if anything happens, i either get back to option 1 or doesn´t show anything anormal. (I have pictures i someone wants to know) What i found weird is that event though the error is possitioned in the chip, however ubuntu 10.04 and 12.04 run fine in a live CD I saw that some people are having issues when LightDM has a non default wallpaper, but i use a default one. Thanks in advance.

  • Remote Display Config.sh Using SSH

    - by john.graves(at)oracle.com
    How often I see people look to VNC, NXMachine, RDP, etc to get a windowing environment on a remote system.  These products are great and I use them too, but there is a fancy feature in SSH to help. ssh –X remoteserver This is a great feature for hooking into headless VirtualBox machines and remote displaying an install wizard. The remote server must have some lines put in the /etc/ssh/sshd_conf file: X11Forwarding yes X11DisplayOffset 10 The second line is optional, but the first is required.  Restart sshd (sudo /etc/init.d/ssh restart). Now I can ssh –X remote server Then run /opt/app/wls10.3.4/wlserver_10.3/common/bin/config.sh to build a new domain. Note: For some reason, the jdk that comes with WebLogic often fails to work on the remote display.  In that case, I modify the config.sh to just use /usr/bin/java (from openjdk-6-jre package).
