  • How to boot a Linux live USB on a Mac?

    - by nambuls
    I have a USB stick with a Fedora 11 live environment on it. It's booting fine on 3 PCs where I've tried it. But I can't get it to boot on a Mac (Intel). When pressing the alt key (or command key, I don't remember which one) during startup I can only choose the "Macintosh HD" and the USB stick doesn't appear.

  • Recommended programming language for linux server management and web ui integration.

    - by Brendan Martens
    I am interested in making an in house web ui to ease some of the management tasks I face with administrating many servers; think Canonical's Landscape. This means doing things like, applying package updates simultaneously across servers, perhaps installing a custom .deb (I use ubuntu/debian.) Reviewing server logs, executing custom scripts, viewing status information for all my servers. I hope to be able to reuse existing command line tools instead of rewriting the exact same operations in a different language myself. I really want to develop something that allows me to continue managing on the ssh level but offers the power of a web interface for easily applying the same infrastructure wide changes. They should not be mutually exclusive. What are some recommended programming languages to use for doing this kind of development and tying it into a web ui? Why do you recommend the language(s) you do? I am not an experienced programmer, but view this as an opportunity to scratch some of my own itches as well as become a better programmer. I do not care specifically if one language is harder than another, but am more interested in picking the best tools for the job from the beginning. Feel free to recommend any existing projects except Landscape (not free,) Ebox (not entirely free, and more than I am looking for,) and webmin (I don't like it, feels clunky and does not integrate well with the "debian way" of maintaining a server, imo.) Thanks for any ideas!

  • How long do uploaded files stay in the tmp folder in Linux Ubuntu?

    - by Jean-Nicolas Boulay Desjardins
    I am building a web application where my users will be able to upload files. After the files are uploaded I need to send the files to two other servers, and after they will be deleted from the server where they were just uploaded to. I am wandering is it a good I idea to keep the uploaded files in the tmp/ folder the time the uploaded files are sent to the other two servers or should I move them to another folder incase they get deleted? I am also wandering because I would like to know if I have to build a cron script to get rid of the files that have been transfered to the other servers so that I get my disk space back.

  • How should I troubleshoot a problematic wireless connection on Linux?

    - by Gearoid Murphy
    I recently purchased a netgear 150 usb wireless dongle for use with my 11.10 Xubuntu amd64 system. Using the network-manager interface, I can see local wireless networks and enter the authentication details for my local wireless lan. Unfortunately, the connection does not seem to work, I keep getting notifications that my wireless has disconnected (but none indicating that I've connected). When I examine syslog, it seems to indicate that I've successfully associated with the wireless switch and that dhcp has successfully acquired an ip address but the log shows that the dhcp process keeps sending requests, eventually dropping the connection. 'ifconfig wlan0' never shows the dhcp address logged in syslog. I suspect that the problem lies with the usb dongle, my configuration or the wireless switch but I am not certain how to isolate the problem, can anyone provide some insight on how I should go about homing in on the cause of this problem or verifying the functionality of the individual components, thanks.

  • Can you get any program in Linux to print a stack trace if it segfaults?

    - by Neil
    If I run a program from the shell, and it segfaults: $ buggy_program Segmentation fault It will tell me, however, is there a way to get programs to print a backtrace, perhaps by running something like this: $ print_backtrace_if_segfault buggy_program Segfault in main.c:35 (rest of the backtrace) I'd also rather not use strace or ltrace for that kind of information, as they'll print either way...

  • How to make Linux to re-detect network interfaces?

    - by ablmf
    For some reason, ifcfg-eth* under /etc/sysconfig/network-script were deleted. Is there any tools that could detect network interfaces and re-generate these files? Another question : If I manually added ifcfg-eth0, is there any method to make it work without reboot? I tried "/etc/init.d/networking restart", and it doesn't work.

  • On linux, what does it mean when a directory has size 0 instead of 4096?

    - by kdt
    Here's a strange thing I haven't seen before -- a directory whose size is reported by ls as 0 instead of 4096, and I can't create any files within it. # ls -ld lib home drwxr-xr-x. 2 root root 0 Feb 7 03:10 home <-- it has zero size dr-xr-xr-x. 11 root root 4096 Feb 4 09:28 lib # touch home/foo touch: cannot touch `home/foo': No such file or directory <-- and I can't create files in it # rm home rm: cannot remove `home': Is a directory <-- look, it really is a dir So what does it mean for a directory to have size 0 instead of 4096? Filesystem is ext4 on fedora core 14. The output of mount is: /dev/mapper/vg_dev-lv_root on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0") /dev/vda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) Output of du -s /home: 0 /home Output of stat /home: File: `/home' Size: 0 Blocks: 0 IO Block: 1024 directory Device: 15h/21d Inode: 34913 Links: 2 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2011-02-07 03:45:46.188995765 -0800 Modify: 2011-02-07 03:11:59.980995019 -0800 Change: 2011-02-06 07:58:45.874995002 -0800

  • Is there a way to save and restore a set of tabs in a linux file manager?

    - by N Rahl
    For a frequent task, I need a file manager window open with about 8 tabs, each a different location. I'd like to be able to open the tabs once and then save them as a "tab set", so that in future sessions, I can simply open a file manager and restore the saved tab set, without having to open each tab manually. I'm running Mint 16 with Thunar, but could use a different file manager if needed. Is there a way to do this?

  • How to disable 3G USB Modem internal storage from being loaded by linux kernel?

    - by Krystian
    Hi, I've got a problem with my 3G modem [Huawei E122]. It has internal storage and kernel assigns a device [/dev/sdX] to it. Because of that, every second time my machine will not boot - kernel panic - as my usb hdd gets assigned /dev/sdb instead of /dev/sda. I cannot use LABEL nor UUID in root= kernel parameter, as it is only available when using initrd, and I can't use it - I am using Debian on my router - mips architecture machine. I have to prevent this from happening, as my router has to start everyday and I have to be sure it works ok. I don't have physical access to restart it when something goes wrong. I don't use my modem internal storage, there's no SD card inserted. However kernel detects the reader and loads it. I can not prevent loading od usb drivers since my hdd is on USB as well. I will appreciate any ideas.

  • Alternative to middle click for Linux in Parallels on a MacBook?

    - by Roland Swingler
    I'm running Ubuntu on Parallels on a MacBook, and there is no middle-click on the MacBook trackpad - which is annoying because it means you can't do X's paste action. Is there an alternative? I'm hoping there is a keyboard binding to X's paste or better a way to bind a keyboard key/combination to the middle-click action. Edit: I know about the emulate three-button mouse option, but that won't work for me because the trackpad only allows you to click one button at a time

  • How to scan multiple pages from a book under Linux?

    - by rumtscho
    I want the process to look like: I choose the correct scan settings (dpi, color depth, etc) I lay the first page on the scanner and trigger the process The scanner scans the page and waits for me to position the next page correctly I confirm that the next page is ready for scanning Repeat the above two steps until I tell the scanner that there are no more pages to come The scanner saves everything into a single PDF. I tried both xsane and gscan2pdf. First problem: they want me to know how many pages will be scanned. This is already a nuisance, but I can do the counting if needed. The main problem is that in step 3, the scanner does not pause. It is probably optimised for being fed loose sheets. The next scan process is triggered automatically as soon as the CCD has returned to the start position. The time the scanner needs to return the CCD is very short and I can't turn the page and position the book properly. Is there a software which can do the scan process in the way I described above, or did I just miss a setting available in xsane or gscan2pdf to make the scanner pause? If it makes any difference, the scanner is an Epson Stylus SX620FW, I run it using the manufacturer-provided driver.

  • Linux Software Raid runs checkarray on the First Sunday of the Month? Why?

    - by mgjk
    It looks like Debian has a default to run checkarray on the first Sunday of the month. This causes massive performance problems and heavy disk usage for 12 hours on my 2TB mirror. Doing this "just in case" is bizzare to me. Discovering data out of sync between the two disks without quorum would be a failure anyway. This massive checking could only tell me that I have an unrecoverable drive failure and corrupt data. Which is nice, but not all that helpful. Is it necessary? Given I have no disk errors and no reason to believe my disks have failed, why is this check necessary? Should I take it out of my cron? /etc/cron.d# tail -1 /etc/cron.d/mdadm 57 0 * * 0 root [ -x /usr/share/mdadm/checkarray ] && [ $(date +\%d) -le 7 ] && /usr/share/mdadm/checkarray --cron --all --quiet Thanks for any insight,

  • On linux how can make a list of files that are owned by a particular owner and then fix the group and owner?

    - by Stuart Woodward
    I have a deep and complex file system where some files have been accidently written by root. I want to change the ownership of those files back to the original owner in one go. I am playing with commands like: find /folder -type f | xargs ls -l | grep "root root" but there is a lot of garbage coming out too. I want to make a list first and then change only the files in that list after confirmation.

  • how is the the linux console displayed to the user and how does the user go about changing the conso

    - by Chris
    I've been searching for the last two day on trying to understand how the console displays itself to the user and how to change the console settings. I've had some luck along the way but nothing that I've found has giving me a real clear explanation of how the console is displayed or how to change or control it's display settings. Some examples that of what I'm looking for are as follows: How is the console displayed on the screen? I know with X11 it uses your graphics card driver to display graphics to the screen, but how is the consoles text mode handled? Could some one ether explain this to me or point me to an in-depth overview of it all? Is it possible to have multi-head support in console mode with separate tty's on each screen? If so how would I go about setting this up? How would you go about changing the size of the console display from the default 80x25 to a custom size? I'm testing anything I find on a debian testing build, which is just the minimal base install on a virtual box. In time I will be using this information to setup my main system which is multi-head with 3 monitors. I would like to be able to support all three displays in console mode if possible.
