  • mount qcow2 snapshots

    - by phhe
    I'm running some Xen-servers and started migrating to KVM. Currently my guests are either running on raw-images or LVMs. I found libvirt providing some very nice snapshot features (virsh snapshot-create, ...) so I decided to use qcow2 instead of raw/lvm. And here is my question: libvirt creates the same sort of snapshots on the qcow2 image as if I use qemu-img - is it possible to mount them ? I read something about qemu-nbd and the possibility of mounting qcow but I could not find a word about snapshots.

  • How can I enforce directory space limits in a OpenVPZ system?

    - by George
    The title says it all. I have some programs on a server (centos4-openvz) that use a directory as temp directory - but pay no attention to the size it grows. I want to enforcee a limit, like this folder cannot exceed 300mb. I would use quota but OpenVZ does not support loop devices to mount a file as such. Any other solutions? (apart from scripting a periodic delete of files in the directory). Editing the application's code to implement such a functionality is not entirely out of the question - if it can be done easily and no other ways exist.. Its written in cpp - but I don't know how to implement it.

  • Why does my Mac address reset after reconnecting?

    - by Mr.Student
    I have ubuntu 12. I'm changing my mac address with ifconfig wlan0 hw ether xx:xx:xx:xx:xx:xx which works. However when I restart my connection my computer resets my mac to my original mac address. I'm guessing that this happens because something calls... ifconfig wlan0 down ... do something before connecting ifconfig wlan0 up ... connect to designated access point I want my mac address to however be the same no matter how many times I disconnect and reconnect, whether to another network or the same one. Also it would be nice to turn off the auto-connect feature for my network-manager with out having to edit each individual connection. Lastly I would like to know how to connect to a wifi network through the terminal and not via gui network manager ubuntu provides.

  • a brand new FS based on a database without using fuse

    - by Devrim
    hi all, To serve millions of files out of a single directory, being able to connect to a drive from hundreds of endpoints, and for some other reasons (to avoid gluster/nfs/all fs based networking solutions), I want to evaluate the possibility of making a filesystem that's based on a mongodb (or any other). Basically, it works like fusefs, every single file is kept in mongo gridfs. In theory, I do, mount mongodbfs /mountPoint mongodb://localhost then when i say touch /mountPoint/test.txt this file is inserted into mongodb. This FS will also store uid/gid and perms with the file, we can throw hundreds of servers to it, and no useradd will be necessary. I'm not thinking to include all the features of FS, just the ones we need. My question is, how do I start my quest in finding resources, books, links, people, developers who'd help me implement this? at least a proof of concept. Is it feasible? What should I expect as a timeline for such undertaking? Please only think about gazillion small files and folders.

  • Execute a script with root permission

    - by Bastien974
    Hi all, I need a script that will chown/chmod some files. This script need to be executable by any user. The problem is that those files are owned by different users, so it needs to be executed as root. I tried the SUID so that any users with X permission can execute the script as root, but seems that it doesn't work with a bash script because of security issue. How can I do that ? thanks.

  • Best practice, or generally best way to set up web-hosting server, permissions, etc.

    - by Jagot
    Hi, I'm about to set up a server upon which a friend and I will be hosting web sites, and I'll be using Debian. I've set up a LAMP solution many times just to using for local testing purposes, but never for actual production use. I was wondering what are the best practices are in terms of setting the server up, in reference specifically to accessing the web root directory. A couple of the options I have seen: Set up a single user account on the server for us both to use and use a virtual host to point to the somewhere in the home directory, e.g. /home/webdev/www. Set each of us up a user account, and grant permissions in some way to /var/www (What would be the best way? Set up a new group?) I want to get this right when I first set this up as there won't be any going back for a while once our first site is up and running. Appreciate any guidance in advance.

  • Remote Program (via ssh) suspends when leaving client computer

    - by Philipp F
    I'm working with MATLAB on a remote computer logging in via ssh -X remotepc and running matlab like matlab &. When I start a long-running process and leave the computer, it seems to suspend the process (after like 30mins being away) such that there is nearly no progress over night. As soon as I come back and wake up the client, the remote process continues with the calculation. I can see this from the load-average values (uptime) Why is that and how can I change this behaviour?

  • How to delete files quicker than rm -rf?

    - by Byakugan
    Is there any way how to delete folder/files quicker than with command rm -rf? It seems my disc is filled with bilions of files (sessions of php5) which were not deleted in cron so I need to delete them manually but it takes hours and it is still not helping reducing the amount. Thank you. My command: rm -rf /var/lib/php5/* Tried also these commands: find /var/lib/php5 -name "sess_*" -exec rm {} \; And perl -e 'chdir "/var/lib/php5/" or die; opendir D, "."; while ($n = readdir D) { unlink $n }'

  • how to remove background layer of djvu file

    - by Jon
    Hello, I've downloaded some files from the Internet Archive. They come in different file formats and most of the time I use pdf. However, sometimes the scans are saves in colour instead of b/w. This makes it difficult/impossible to read on a dedicated ebook reader. In that case I downloaded the djvu files as on the PC you can select which layer (color, bw,fore,back) one would like to see. Selecting the bw gives excellent results. However, the ebook reader does not has this option. The question is, how can I remove /extract a layer from the djvu file and save only this layer. So far I've tried the following two approaches: 1) select bw in the djvu viewer on the PC and printed to postscript file. Followed by a ps2pdf conversion. This works, but generates a fairly large pdf file. Sure, I can again upload it to any2djvu but it just seems to much manual work for each file. 2) I tried the shared annotation feature and said (mode bw). This works on the PC as desired but is ignored on the ebook reader as the other layers are still present. Any help or suggestions would be greatly appreciated.

  • startx error no desktop manager

    - by WikiWitz
    I have Backtrack 5R2 KDE. I started recovery mode and did a failsafe xorg configuration. After that, I cannot load the KDE manager when I enter the startx command after logging in. Whenever I do a startx command (as root), the result resembles the following: This is not the actual output (I just drew this with MS paint because I cannot do a printscreen). The screen is just black with the icon in the upper left corner. The other pop-up menu appears when left-clicking the mouse. I tried the cp xorg.conf.failsafe xorg.conf advice from other websites with no luck. I have also tried the 'reconfigure option(s)' form the recovery mode with no success.

  • Why can't I get out of display mirror mode?

    - by Roy Smith
    I've been running Ubuntu (10.04.1 LTS, 64-bit) for a while and just replaced my hardware with a faster machine with an ATI Radeon HD 5700 video card. I've got twin 1920 x 1080 displays. I downloaded the latest driver (ati-driver-installer-10-9-x86.x86_64.run) from the ATI web site and installed that. I've gone through a few rounds of playing with /etc/X11/xorg.conf, and can't get things right. At the moment, it's in display mirroring mode, and I can't figure out how to get it out of mirror mode. If I run Monitor Preferences, there's a "Same image in all monitors" checkbox. If I uncheck that, the little preview window switches to show two monitors. When I click Apply, it asks me to log out and log back in again. When I do that, I'm right back to mirrored mode. What's really weird is that I'm currently running a copy of xorg.conf from a coworker's machine. He's got identical hardware, and his display works fine. So, I'm inclined to think there's something else going on other than the conf file. Any ideas what might be wrong?

  • 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 to record desktop session with sound on Moblin?

    - by Moblin Newbie
    I have tried to record my desktop session with sound on a netbook running Moblin, but I can't seem to be able to record sound. xvidcap just says error accessing /dev/dsp. Are there some options I should pass to xvidcap? Should I use some other recording application? Update: I am using the latest xvidcap (1.1.7) and have read the FAQ. Unfortunately Moblin' gnome-volume-control looks nothing like what is linked to from the xvidcap FAQ; there is no way to to set or even look at the details the screenshot shows, as far as I know. alsamixer shows pulseaudio is used, if that gives anyone any clues. The device is Acer Aspire One.

  • SELinux - Allow multiple services access to same /home/dir

    - by Mike Purcell
    I currently have SELinux enabled and have been able to configure apache to allow access to /home/src/web with a chcon command granting the 'httpd_sys_content_t' type. But now I am trying to serve the rsyslogd.conf file from the same directory, but every time I start rsyslogd I see an entry in my audit log saying that rsyslogd was denied access. My question is, is it possible to grant two applications the ability to access the same directory, while still keeping SELinux enabled? Current perms on /home/src: drwxr-xr-x. src src unconfined_u:object_r:httpd_sys_content_t:s0 src Audit log message: type=AVC msg=audit(1349113476.272:1154): avc: denied { search } for pid=9975 comm="rsyslogd" name="/" dev=dm-2 ino=2 scontext=unconfined_u:system_r:syslogd_t:s0 tcontext=system_u:object_r:home_root_t:s0 tclass=dir type=SYSCALL msg=audit(1349113476.272:1154): arch=c000003e syscall=2 success=no exit=-13 a0=7f9ef0c027f5 a1=0 a2=1b6 a3=0 items=0 ppid=9974 pid=9975 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=30 comm="rsyslogd" exe="/sbin/rsyslogd" subj=unconfined_u:system_r:syslogd_t:s0 key=(null) -- Edit -- Came across this post, which is sort of what I am trying to accomplish. However when I viewed the list of allowed sebool params, the only relating to syslog was: syslogd_disable_trans (SELinux Service Protection), seems like I can maintain the current SELinux 'type' on the /home/src/ dir, but set the bool on syslogd_disable_trans to false. I wonder if there is a better approach?

    I have PHP installed properly from the Remi repo on CentOS 6 (64 bit). As shown in the image above, the PHP information page shows sessions as working and installed, yet I get this error: Fatal error: Call to undefined function session_create() in /var/www/lighttpd/index.php on line 1 I've tried multiple reinstalls, different PHP RPM's, and yet nothing will get sessions going. How can I get PHP sessions working?

  • How do you persist installed software & configurations on an Amazon EC2 instance?

    - by Richard
    I've gotten a base Debian AMI up and running and now I need to know the best way to maintain it. I've ran the updates (aptitude update/upgrade) and installed/configured my software (Apache, Ruby, etc.) but if I reboot the instance or start a new one I'll have to do all this work over again. How do you persist these types of things over a reboot? Do you build a new AMI every time you adjust some tiny piece of the system? Or is there some way to feed it a script on startup that configures it in "real-time"? I know I could go all the way with a Reductive Labs Puppet style setup but that's a bit too much for my needs right now (1-2 servers). Any best practices on this? Update: I found a bit of information on using User-Data to run scripts at instance boot time.

  • Creating software raid on spare internal drives with Fedora

    - by Wizzard
    Hi there, I got two internal 80GB drives which are blank and just sitting in the case. I have tried googling for the steps or some info but I can only find out how to setup raid when I am first installing Fedora - not for doing when already setup. These are two new (old) drives, that are blank, the system is not on them so should really just be as simple as formating and then binding them to a raid - but can't find any information. Any clues?

  • Still no external sound after installing ubuntu 10.04

    - by Walter
    As suggested I upgraded. Same as before except now not even the speaker control in the application bar. Please help. Background: I have Ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal and ran alsamixer which seems to recognize my sound card, though the driver is not listed in System Administration Hardware Drivers; the only driver listed is my graphics card. Setup: I have a Dell 8250. Speakers are plugged into the SB live card. Woofer and 2 speakers using transformer.

  • scp to remote servers stalls, unable to isolate cause

    - by Rolf
    When I copy a large file (100+mb) to a remote server using scp it slows down from 2.7 mb/s to 100 kb/s and downward and then stalls. The problem is that I can't seem to isolate the problem. I've tried 2 different remote servers, using 2 local machines (1 osx, 1 windows/cygwin), using 2 different networks/isps and 2 different scp clients. All combinations give the problem except when I copy between the two remote servers (scp). Using wireshark I could not detect any traffic volume that would congest the network (although about 7 packets/sec with NBNS requests from the osx machine). What in the world could be going on? Given the combinations I've used there doesn't seem to be any overlap in the thing that could be causing the trouble.
