  • Find directories not containing a specific directory

    - by Morgan ARR Allen
    Been searching around for a bit and cannot find a solution for this one. I guess I'm looking for a leaf-directory by name. In this example I'd like to get a list of directories call 'modules' that do NOT have a subdirectory called module. modules/package1/modules/spackage1 modules/package1/modules/spackage2 modules/package1/modules/spackage3/modules modules/package1/modules/spackage3/modules/spackage1 modules/package2/modules/ The list I desire would contain modules/package1/modules/spackage3/modules/ modules/package2/modules/ All the directories named module that do not have a subdirectory called module I started with trying something this with no luck find . -name modules \! -exec sh -c 'find -name modules' \; -exec works on exit code, okay lets pass the count as exit code find . -name modules -exec sh -c 'exit $(find {} -name modules|grep -n ""|tail -n1|cut -d: -f1)' \; This should take the count of each subdirectory called modules and exit with it. No such love.

  • How do I make kdump use a permissible range of memory for the crash kernel?

    - by Philip Durbin
    I've read the Red Hat Knowledgebase article "How do I configure kexec/kdump on Red Hat Enterprise Linux 5?" at http://kbase.redhat.com/faq/docs/DOC-6039 and http://prefetch.net/blog/index.php/2009/07/06/using-kdump-to-get-core-files-on-fedora-and-centos-hosts/ The crashkernel=128M@16M kernel parameter works fine for me in a RHEL 6.0 beta VM, but not on the RHEL 5.5 hosts I've tried. dmesg shows me: Memory for crash kernel (0x0 to 0x0) notwithin permissible range disabling kdump Here's the line from grub.conf: kernel /vmlinuz-2.6.18-194.3.1.el5 ro root=/dev/md2 console=ttyS0,115200 panic=15 rhgb quiet crashkernel=128M@16M How do I make kdump use a permissible range of memory for the crash kernel?

  • How to know when the kernel was last compiled?

    - by Mehmet Tuncal
    I have installed a linux distro and I "think" it is vulnerable to kernel exploits. I have to update kernel but I need to know if it is really compiled in year 2003? How can I know if additional updates are made to the kernel? Linux gandalf 2.4.21-4.ELsmp #1 SMP Fri Oct 3 17:52:56 EDT 2003 i686 i686 i386 GNU/Linux Does also "smp" mean that it is safe from latest threats or something? Thank you.

  • Radeon Mobility HD 5470 Not Working on Ubuntu 10.10

    - by Promather
    I recently bought a new HP DV6-3118SA laptop, but I am having a very discouraging problem with the graphics card. The graphics card is Radeon Mobility HD 5470. It doesn't install by default, but I do get some message suggesting to install the driver. If I install that driver, the next time I reboot, the screen goes blank and that's it! The same happens if I install the proprietary driver (fglrx) from ATI website. Could you please help me with this?

  • Working with anonymous modules in Ruby

    - by Byron Park
    Suppose I make a module as follows: m = Module.new do class C end end Three questions: Other than a reference to m, is there a way I can access C and other things inside m? Can I give a name to the anonymous module after I've created it (just as if I'd typed "module ...")? How do I delete the anonymous module when I'm done with it, such that the constants it defines are no longer present?

  • Why is bzip2 needed in the kernel patch instructions?

    - by user12657
    This was from here. Extract the patch tar -xvzf /usr/src/web100-2.5.22-200810130047.tar.gz bzip2 web100/ web100-2.6.27-2.5.22-200810130047.patch Test the patch bzip2 -dc /usr/src/linux/web100/ web100-2.6.27-2.5.22-200810130047.patch.bz2 | patch -p1 --dry-run I looked at the .patch, the diff output of many files and the file .patch.bz2 after the bzip2 command which is too also the diff output of many files, they seem to be the same. My question is why is bzip2 even needed to turn the .patch into a .patch.bz2? Is it for the redirection to std output from the -dc option for the patch command? Even if it is, why not just not just use the patch command in the form something like this:patch -p1 < patchfile? I don't see why the bzip2 is done here. Also, I think the bzip2 might have an extra space in the command after web100/, right?

  • How can I upgrade to Lubuntu 14.04.1 withot a PAE kernel?

    - by Richard
    On my Dell Latitude D800 laptop, which has an old Pentium M without PAE support, I was able to successfully install Lubuntu 14.04 from the CD. When I try to upgrade, I get the error: PAE not enabled Your system uses a CPU that does not have PAE enabled. Ubuntu only supports non-PAE systems up to Ubuntu 12.04. To upgrade to a later version of Ubuntu, you must enable PAE (if this is possible) see: http://help.ubuntu.com/community/EnablingPAE I have seen the Communit Wiki page for PAE. The suggestion is to add forcepae to the command line options. When I do this, I get the same message. Moreover, dmesg does not indicate PAE was ever enabled. Is there anything else I can ry to get Lubuntu to upgrade correctly?

  • Ubuntu not booting after install from USB (kernel panic?)

    After booting fine frome a live USB I installed it and everything was going swimmingly but when I try to boot from the hard drive it just stops and I have to do a hard reboot. I tried booting into grub as recommended in other questions but it wouldn't work. Here is a photo of the boot once stuck: Same for recovery boot: I've got an Asus K43SJ laptop with an intel i5, 4Gb of RAM, an nVidia GeForce GT 520M and a 750Gb hard drive.

  • Why is there an extra HDD under /dev being added in my Linux Kernel?

    - by user1279156
    I have created a Linux kernel and for some reason an extra drive is always added at bootup. My hard drive is listed as /dev/sdb. /dev/sda is created too, and it is 8 MB in size. I can't find anything in the kernel config that is creating this, but if I use a different kernel it is not there. Kernel logs show it as an attached SCSI device, looks just like my hard drive but only 8 MB, and has no partition table. It also doesn't appear to be a physical device. I've tried the kernel on many different models of PCs and it is always there. Does anyone know how to remove it? /dev/disk/by-id gives me: scsi-1AMCC_U21413034D98EB000584 scsi-1AMCC_U21413034D98EB000584-part1 scsi-353333330000007d0 scsi-SATA_ST3250312AS_5VY7SH42 scsi-SATA_WDC_WD800JD-60L_WD-WMAM9Y085675 scsi-SATA_WDC_WD800JD-60L_WD-WMAM9Y085675-part1 scsi-SATA_WDC_WD800JD-60L_WD-WMAM9Y085675-part2 hdparm -i /dev/sda gives me an "invalid argument". dd if=/dev/sda of=sda.img the resulting file does not have any content sdparm results: /dev/sda: Linux scsi_debug 0004 Device identification VPD page: Addressed logical unit: designator type: T10 vendor identification, code set: ASCII vendor id: Linux vendor specific: scsi_debug 2000 designator type: NAA, code set: Binary 0x53333330000007d0 Target port: designator type: Relative target port, code set: Binary transport: Serial Attached SCSI (SAS) Relative target port: 0x1 designator type: NAA, code set: Binary transport: Serial Attached SCSI (SAS) 0x52222220000007ce designator type: Target port group, code set: Binary transport: Serial Attached SCSI (SAS) Target port group: 0x100 Target device that contains addressed lu: designator type: NAA, code set: Binary transport: Serial Attached SCSI (SAS) 0x52222220000007cd designator type: SCSI name string, code set: UTF-8 transport: Serial Attached SCSI (SAS) SCSI name string: naa.52222220000007CD

  • How do I tell which kernel module is servicing a /dev device?

    - by regulatre
    How do I find out which kernel module (as seen by typing lsmod) is servicing a particular device in /dev ? In other words, say I have a device, /dev/mouse0 and I want to find out which kernel module is installed to service that device. How do I do that? Another way to look at this is, some loaded kernel modules associate themselves with a device in /dev. How does one find out which device(s) a module is "attached" to?

  • How does a linked library combined with the main executable program file interact with a kernel?

    - by I ask Questions For a Reason
    I was attempting to find an answer to this, and I did to some degree, but definitely not anywhere good enough to form a respectable, sensible and clear answer. If I am using Windows, Mac, Linux, or nearly any modern made OS for desktop IBM-compatible PCs, laptops, even tablets and smartphones, there's virtual memory. Clearly, compiling, at least on Windows I know this, an executable object file, such as a simple C "Hello World" output to a terminal, will be linked with the standard library, and several other Window's system software, dynamic linked libraries, and the like. However, how does linking all of these executables together or resources form a connectable interaction with, say, a device driver or any other stuff on the lower level?

  • Why not port Linux kernel to Common Lisp?

    - by rplevy
    Conventional wisdom states that OS kernels must be written in C in order to achieve the necessary levels of performance. This has been the justification for not using more expressive high level languages. However, for a few years now implementations of Common Lisp such as SBCL have proven to be just as performant as C. What then are the arguments against redoing the kernel in a powerfully expressive language, namely Common Lisp? I don't think anyone (at least anyone who knows what they are talking about) could argue against the fact that the benefits in transparency and readability would be tremendous, not to mention all the things that can't be done in C that can be done in Lisp, but there may be implementation details that would make this a bad idea.

  • win32 API vs Linux Kernel API

    - by Nik
    Is there anything that can be done using Win32 API that cannot be done using Linux kernel API. I'm asking this, because back in Lab where I work we use Ixia and Agilent Technologies H/W. and these H/W (Signal processes or Packet generator) worth 10s of thousand of Dollars run windows as their OS. Why didn't they choose Linux. I've seen Linux in routers and firewall but not in real Heavy duty H/W like Ixia. This preference of windows over Linux made me think is there any limitation in Linux API or its just licensing thing.

  • Use of double pointer in linux kernel Hash list implementation

    - by bala1486
    Hi, I am trying to understand Linux Kernel implementation of linked list and hash table. A link to the implementation is here. I understood the linked list implementation. But i am little confused of why double pointers is being used in hlist (**pprev). Link for hlist is here. I understand that hlist is used in implementation of hash table since head of the list requires only one pointer and it saves space. Why cant it be done using single pointer (just *prev like the linked list)? Please help me.

  • Converting kernel image from ELF to PE

    - by Frank Miller
    I am using Msys to build a home brew kernel that I wrote under Linux. Linux used ELF for its binary format and Msys uses PE. I have the source setup to allow it to be booted by Grub using the Multiboot spec. At the end of the build, I get some undefined symbols: init.o:init.S:(.text+0x14): undefined reference to `edata' main.o:main.c:(.text+0x121): undefined reference to `_alloca' main.o:main.c:(.text+0x126): undefined reference to `__main' ../../lib\libkern.a(mem.o):mem.c:(.text+0x242): undefined reference to `_end' ../../lib\libkern.a(mem.o):mem.c:(.text+0x323): undefined reference to `_end' These appear to be ELF oriented symbols. If anyone can advise me on how these should be dealt with in the PE world, e.g. if there are equivalents, it would help me out a lot!

  • Where does output of print in kernel go?

  • What kernel modules are required for wi-fi to work?

    - by Leonid Shevtsov
    My custom-built 2.6.32 kernel cannot connect to any WPA-protected network. The kernel includes (probably?) everything that should be needed for wifi, including IPv4 network support (IPv6 is disabled), the ath5k wireless driver (which is used in the generic Ubuntu 2.6.31 kernel) and all crypto APIs. The card is being detected, however, iwlist scan returns wlan0 Failed to read scan data : Network is down and network-manager log says <info> (wlan0): driver supports SSID scans (scan_capa 0x01). <info> (wlan0): new 802.11 WiFi device (driver: 'ath5k') <info> (wlan0): exported as /org/freedesktop/NetworkManager/Devices/1 <info> (wlan0): now managed <info> (wlan0): device state change: 1 -> 2 (reason 2) <info> (wlan0): bringing up device. <info> (wlan0): preparing device. <info> (wlan0): deactivating device (reason: 2). supplicant_interface_acquire: assertion `mgr_state == NM_SUPPLICANT_MANAGER_STATE_IDLE' failed <info> modem-manager is now available <WARN> default_adapter_cb(): bluez error getting default adapter: The name org.bluez was not provided by any .service files <info> Trying to start the supplicant... <info> (wlan0): supplicant manager state: down -> idle <info> (wlan0): device state change: 2 -> 3 (reason 0) <WARN> nm_supplicant_interface_add_cb(): Unexpected supplicant error getting interface: wpa_supplicant couldn't grab this interface.
