Activity monitor gives me a mysqld process running by me, and everytime i KILL the process both via Activity Monitor and via kill =9 pid it starts right back up.. Sampling the process points back to the MAMP mysqld.. wtf?! About to throw MAMP out the window and boot up a VM of CentOS =)

  • Backup data from RAID 1 disk out of its server

    - by Doomsday
    I'm facing with a pretty easy problem in my opinion. I've extracted a working disk from a RAID1 and I'm looking to copy only data (FS and RAID configuration doesn't matter) into another location (another FS). My problem is I'm not able to mount properly this disk into another linux. I've first looked the partition table : # fdisk -l /dev/sdc Disk /dev/sdc: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 1249535699 624767818+ fd Linux raid autodetect /dev/sdc2 1249535700 1250017649 240975 fd Linux raid autodetect /dev/sdc3 1250017650 1250258624 120487+ 82 Linux swap / Solaris I've understood I should use dmraid tools.

Anyone has a clue ?

  • Linux will not activate wireless after device has been re-enabled

    - by XHR
    Using a Eee 900A netbook by Asus. By pressing Fn + F2, I can disable or enable the wireless chip on the netbook, a blue LED indicates the status. I've been able to connect to wireless networks just fine with this netbook. However, if the wireless chip ever becomes disabled, I have to reboot to get my network connection back. This generally happens when suspending. For some reason the LED will be off and I have to hit Fn + F2 for it to light up again. However, after doing so, Linux will not reconnect to the network. It simply changes the wireless status from "wireless is disabled" to "device not ready". Even worse, I've recently had issues with the chip being enabled at boot, thus making it nearly impossible to get connected. I've searched around on-line but haven't found much of anything useful on this. This happens on all kinds of different distros including Ubuntu 9.10 Netbook, EeeBuntu 4 beta, Jolicloud and Ubuntu 10.04 Netbook. Edit I noticed this question is getting a lot of views. To give a quick update, I never did resolve this issue with the given distro's. However, I'm currently running Ubuntu 10.10 netbook edition and this issue has gone away.

  • Second monitor stopped being recognized by Windows

    - by Eric J.
    One of the developer PC's running Windows Vista Ultimate had the second monitor stop being recognized in Windows overnight. There were no hardware or driver changes at the time, though I have subsequently updated to the latest nVidia drivers (card is NVIDIA GeForce 210). The non-recognized monitor IS recognized during the boot sequence. In fact, only the "bad" one shows the POST or the Windows loading screen. At some point during Windows initialization after the loading screen disappears and before the logon screen appears, the active monitor switches. Any thoughts? UPDATE: When I open the Vista monitor properties window, I see my primary display and secondary display depicted. The primary one is portrayed as the regular blue box, but the secondary one is portrayed greyed-out. I have the option to "Extend desktop to this monitor", the only resolution is 800x600, and all of the advanced monitor properties are greyed out as well. If I opt to extend the desktop, the greyed-out box turns blue, when I then select Apply the screens flash as usual and I'm given the 15 second countdown to accept the new settings and when I do, everything returns to the previously broken state... secondary monitor is portrayed greyed-out again. At no point is the desktop shown on the secondary monitor.

  • Two monitors with Mac Mini - one displays black despite receiving a signal

    - by alex
    My Mac Mini outputs to my two new monitors - Dell U2311Hs. The LED on the bezel displays blue when receiving a signal, or yellow otherwise. Both screens are displaying blue. It also seems my Mini can see both of them... However, one of them is black. It just displays black, but appears to be receiving a signal (when I turn the Mac off, it then displays No Signal). To make things weirder, on startup, the boot up (white with Apple logo) appears on the right monitor (the one that now displays black). Occasionally, it flickers up on the black screen for 1 second. I have tried Detect Displays. It appears to do nothing. I'm also running a dual monitor KVM. Video connections are DVI-D. How can I fix this situation? Thanks. Update This is the weirdest thing - I used the DVI-D cable that came with the KVM and it seems to have fixed it - I didn't both because it looks identical to any other DVI cable (in form an pin out). So, I will accept an answer if someone can tell me what may be the difference in these cables?

  • Power Outage Interrupted Upgrade from Windows Vista Ultimate to 7 Ultimate, Reverted to Vista, Now Vista is failing... What Next?

    - by tednewk
    I was in the midst of what seemed to be a successful upgrade from Vista Ultimate to 7 Ultimate when there was a brief blackout. The upgrade failed and Windows reverted back to Vista. Now Vista is very slow to boot, has problems waking back-up from inactivity and quickly loses it's wireless connection. The wake-up problem manifests itself as the mouse is clearly shown on a black screen but I have no access to the Desktop or Taskbar or Explorer. Even Alt-Ctrl-Delete doesn't seem to work. No task menu, no reboot. Hitting the reset button reboots the machine with the usual Black Screen warnings offering Safe Mode. I tried to do a system restore to a point before the upgrade. That didn't seem to work. My guess is that my system is a mutant with parts of Vista and parts of 7 crashing each other. I would like avoid a clean install if at all possible to avoid reinstalling other software. What should I try now? My thoughts are: My a system back-up to lock the computer in place Trying a second 7 upgrade If that appears to be working make another back-up If not reload back-up and try a repairing Vista from DVD. If that appears to work make another back-up, let system stablize about a week then try 7 install again If that doesn't work are there any other options to try before settling for a clean install? Another complication, I am doing this by "remote control". I'm traveling with my job and I'll be talking my son through it over the phone. (Kind of like the landing the 747 cliche from all the 70's adventure shows!) So is there a way of simplifying the steps? Thanks Ted

  • How to migrate WinXP from failing old HD to new one

    - by Péter Török
    Following this issue, we have all our important data backed up now. I also bought and installed a new replacement hard disk (WD 160GB PATA) as secondary (slave) drive. I created two primary NTFS partitions on it: a 40 GB system partition, and a 110GB data partition. In theory I could start reinstalling WinXP from scratch on the new system partition, then copying over all user data from the old drive to the new data partition. Once this is done, I could even throw away the old drive, or keep it just to see what happens. (Note: I don't want to clone the whole drive as it contains a dual boot setup with an old Linux installation which I don't need anymore, and anyway, a fresh reinstall would do WinXP good to get rid of many years' clutter.) However, I am lazy :-) The old HD is still functioning, the problem has not manifested again since. So I feel there is no need to hurry with a complete OS reinstall. What I don't know though is whether I will be able to install WinXP on the new system partition at a later stage without affecting the contents of the data partition on the same drive. If this is possible, I can just move over all our data to the new data partition to have it safe, then continue running WinXP from the old drive as long as it works. Does anyone see any problems/risks with this plan?

  • Replacing HD in an MacOS 10.6.8 server caused all shares to fail

    - by Cheesus
    I'm hoping someone might have a helpful suggestion about this problem. We have 2 MacOSX servers available for file sharing. (quad Xeons - 2GB RAM, both 10.6.8), No.1 is an Open Directory Master with 50+ user accounts, No.2 has only 2 local accounts (/local/Default) and looks at the OD Master for all user accounts (/LDAPv3/10.x.x.20/) Both servers have 3 internal HD's, The boot volume with only Server OS and minimal Apps. A 'DataShare' HD (500GB) and a backup drive (500GB). After upgrading the DataShare HD in Server No.2 from a small internal HD (500GB) to larger capacity (2TB) drive, users are unable to connect to shares on Server No.2. Users get an error "There are no shares available or you are not allowed to access them on the server" The process I followed was to use Carbon Copy Cloner to create an exact copy of the original data drive (keeps all ownership data, UID, permissions, last edit date and time). Everything booted up ok, no indication there was any issues. (Paths to the sharepoint look good) Notes during troubleshooting - Server1 is operating perfectly, all users can access shares and authenticate etc. - I've checked the SACL (Server Access Control List) settings is ok. - On Server2 in the Server Admin' app, I can see all the shares listed ok. The paths seem valid, I can disable / reenable the shares, no errors. - On Server2 'workgroup manager' lists all the accounts from the OD Master in the LDAP dir view. All seems fine from here. Basically everything looks normal but no file shares on Server2 can be accessed from regular users.

  • IBM BladeCenter S: Disk Configuration

    - by gravyface
    Have just the one storage bay right now (SAS 15K 600GB x 6) and have configured one storage pool in RAID 10 with 4 disks (and two global spares). For each blade, I've created a volume and mapped accordingly: Blade #1 400 GB Blade #2 200 GB Blade #3 100 GB Blade #4 100 GB When I boot up Blade 1 and enter into the UEFI Setup (F1) followed by the Adapters and UEFI Drivers LSI Logic Fusion MPT SAS Driver Utility, I see 4 disks: two are the on-board 73GB drives, the other two are 200GB each and assume I'm being presented with two logical disks from the volume I created and mapped to this blade. I was a bit surprised by this: I figured I would've been presented with one logical drive per volume, not two. I'm assuming I can just configure whatever RAID level I wish that supports two disks, but not really sure what the benefits/trade-offs here. Should I go with RAID 10 on top of RAID 10? RAID 0? Software RAID 0/1/10? Does it even matter? If this is "normal" to see two disks, then I'm going to likely just do some benchmarking and see if it makes a difference changing the RAID levels (my guess is no); if this is not normal, well, please let me know. :)

  • CentOS Installation on a Cisco MCS 7800

    - by William
    Hello, I'm having some problems installing CentOS 5.5 Final (i386) Onto my server, a Cisco MCS 7800. The problem comes very early into the installation. When the welcome screen comes up ans gives you the option on how to boot into the DVD, Ill press enter to go into the graphical installer. The Screen will then have a blinking cursor in the top left of the screen and will never go away (I thought that it just might need time but I let it sit for over 5 hours.) I then booted into it again and tried using Linux Text thinking it was a problem with graphical installer. That didn't work, same problem. Then I tried a DVD of RHEL 5 and got the same problem, both graphical and Linux text. At this point i think its a hardware problem. The Server has 2GB of ECC RAM, 1 Pentium 4 CPU @ 3.06GHZ and 2 WD Hard Drives (80GB) Configured for RAID 0. ( Also there is a option in the BIOS for what OS type and that is set to Linux.) If anyone has any idea what is going on, it would be helpful. ================Edit================== ooshro, typing "text" doesn't change a thing. still stuck at the blinking cursor. I looked it up and its really the same thing as typing "linux text", which as stated in the first part of my question, i've already done.

  • Liked Arch Linux - but I am still not sure if its the right distro for me...

    - by BlackAndGold
    As the title says... I used Arch Linux for a while and liked it a lot: leightweight, sleek, fast and well documented with a great community. However I had to format my hd and for the sake of being too lazy to reinstall arch, I used windows 7 exclusively for a while. Now I want to get back to linux again (still dual boot), mainly for web development purposes and using handy tools such as rsync ect. Again, I liked Arch, but there is too much tweeking, too much reading up and too much figuring out what to do as well es some bad suprises especially when you need them the least and when just quickly want to get some work done. I kind of would like to have a little more "out of the box" distro that is still fast and somewhat leighweight and of course reliable. I actually considered Ubuntu, which I am not too big of a fan of, but I will still give the minimal install a shot. However other distros seem interesting as well, such as crunchbang and mint debian ecpecially. My question, hoping this isn't too boring for many you, what is the right distro for me?

  • Migrating from one linux install to another: How to keep the second disk around?

    - by Jim Miller
    I've got a linux box running Fedora 19 that I want to move to CentOS 6.4. Rather than trying to do something fancy with the current disk (which has also accumulated a lot of sludge over the years), I'm going to get a new disk, put CentOS on that, and then move the to-be-preserved bits of stuff from the old disk to the new one. I haven't done this yet, but I presume it should be semi-straightforward -- do the CentOS install on the new disk, mount the old disk on /olddisk or somesuch, and start copying. However, I'm not sure how to handle getting the machine to recognize the new empty disk as the target of the CentOS install (I suppose I can just pull the old disk during the installation), remember that this is the intended boot disk once the install has happened), and tweak /etc/fstab (right?) to set up the old disk on the desired mount point. (Both disks are, or will be, SATA.) I could probably hack it together without losing too much hair or doing too much damage, but could anyone offer some advice that would get/keep me on the right track? Thanks!

  • Extending partition on linux gparted but not more space in the vm

    - by Asken
    I have a vm test installation of a linux running a build server. Unfortunately I just pressed ok when adding the disk and ended up with an 8gb drive to play with. Well into the test the builds are consuming more and more space, of course. The vm drive was resized to 21gb and using gparted I expanded the drive partitions and that all worked fine but when I go back into the console and do df there's still only 8gb available. How can I claim the other 13gb I added? fdisk -l Disk /dev/sda: 21.0 GB, 20971520000 bytes 255 heads, 63 sectors/track, 2549 cylinders, total 40960000 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0006d284 Device Boot Start End Blocks Id System /dev/sda1 * 2048 499711 248832 83 Linux /dev/sda2 501758 40959999 20229121 5 Extended /dev/sda5 501760 40959999 20229120 8e Linux LVM vgdisplay --- Volume group --- VG Name ct System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 19.29 GiB PE Size 4.00 MiB Total PE 4938 Alloc PE / Size 1977 / 7.72 GiB Free PE / Size 2961 / 11.57 GiB VG UUID MwiMAz-52e1-iGVf-eL4f-P5lq-FvRA-L73Sl3 lvdisplay --- Logical volume --- LV Name /dev/ct/root VG Name ct LV UUID Rfk9fh-kqdM-q7t5-ml6i-EjE8-nMtU-usBF0m LV Write Access read/write LV Status available # open 1 LV Size 5.73 GiB Current LE 1466 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:0 --- Logical volume --- LV Name /dev/ct/swap_1 VG Name ct LV UUID BLFaa6-1f5T-4MM0-5goV-1aur-nzl9-sNLXIs LV Write Access read/write LV Status available # open 2 LV Size 2.00 GiB Current LE 511 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:1

  • What user information is exposed via a browser?

    - by ipso
    Is there a function or website that can collect and display ALL of the user information that can be obtained via a browser? Background: This of course does not account for the significant cross-reference abilities of large corporations to collate multiple sources and signals from users across various properties, but it's a first step. Ghostery is just a great idea; to show people all of the surreptitious scripts that run on any given website. But what information is available – what is the total set of values stored – that those scripts can collect from? If you login to a search engine and stay logged in but leave their tab, is that company still collecting your webpage viewing and activity from other tabs? Can past or future inputs to pages be captured – say comments on another website? What types of activities are stored as variables in the browser app that can be collected? This is surely a highly complex question, given to countless user scenarios – but my whole point is to be able to cut through all that – and just show the total set of data available at any given point in time. Then you can A/B test and see what is available with in a fresh session with one tab open vs. the same webpage but with 12 tabs open, and a full day of history to boot. (Latest Firefox & Chrome – on Win7, Win8 or Mint13 – although I'd like to think that won't make too much of a difference. Make assumptions. Simple is better.)

  • K8NDRE motherboard in server fails to complete BIOS load with error 0078

    - by John
    K8NDRE motherboard with 4 sata drives, was running fine. Drives had raid-0 and raid-1 partitions, using mdadm. The onboard raid is disabled. Upon reformatting the drives, setting a new partition structure and new raid partitions, the bios fails to finish loading, with 0078 in the bottom right corner. Tried using completely new set of drives, and bios worked fine. Able to boot from a usb, format the drives, partition them, start raid, and then installed os. Reboot and received the same error from the bios, 0078. Works fine if I unplug the sata drives. Any thoughts? Physical inspection reveals no damage cables, connectors, or capacitors. Server was running happily for over a year, and this is the first problem it has had. Per Michael Hampton's answer: The drives, unjumpered and supporting sata III worked fine originally, and worked fine for formatting and having new partitions and raid installed on them. I did try jumpering one, with no change. If I put a brand new unformatted drive in, the motherboard recognizes it and I can proceed with formatting and installing. When I reboot, I get the 0078. I have 4 sata cables-the board supports 4 drives, so I tried each and no change. I am close to calling the motherboard done.

  • VirtualBox doesn't see raw partitions

    - by smbear
    What I want to achieve is to set up virtual machine with VirtualBox. Host OS is Windows 7 Home Premium, guest will be (k)Ubuntu 12.04 on a raw partition. The first problem is that when I issue following command: VBoxManage.exe internalcommands listpartitions -rawdisk \\.\PhysicalDrive0 I get following result: Number Type StartCHS EndCHS Size (MiB) Start (Sect) 1 0xee 0 /0 /1 1023/254/63 715404 1 I'm guessing that VirtualBox is unable to see my partitions. If I use diskpart tool, then all partitions are listed correctly (note Polish language version of Windows): DISKPART> select disk 0 Obecnie wybranym dyskiem jest dysk 0. DISKPART> list partition Partycja ### Typ Rozmiar Przesuniecie ------------- ---------------- ------- ------------ Partycja 1 System 200 MB 1024 KB Partycja 2 Zarezerwowany 128 MB 201 MB Partycja 3 Podstawowy 139 GB 329 MB Partycja 5 Nieznany 4883 KB 140 GB Partycja 6 Podstawowy 50 GB 140 GB Partycja 7 Podstawowy 484 GB 190 GB Partycja 4 Odzyskiwanie 24 GB 674 GB Additional note: my PC is using EFI to boot OS. Basing on the results listed above, I believe that: I messed up with my partition table. Something is wrong with VirtualBox. Can anyone help with this issue?

  • Failover Cluster Quorum Failing

    - by oruchreis
    Hi, I have two nodes which boots from iscsi to implement windows 2008 cluster. And I'm using disk majority option as quorum over iscsi. But when the quorum's iscsi connection failed(May be san server reset), the failover cluster is failed too. If I reset one of the nodes, it can open, but its system disk goes offline. I cant change its status as online, because it says that its reserved by failover cluster(disk is on iscsi, beacuse iscsi boot). And this disk works as readonly. Anything on it cant be deleted or written. So, I cant rejoin the node to the cluster again. I have to reinstall windows. So, what I'm asking is, how can I implement more quorum backup? I mean, can I use both disk majority and file share majority at same time? AFAIK, every nodes also keep the quorum's copy too. But I don't know sometimes san servers goes offline. And quorum's iscsi connection and nodes' iscsi connections get lost. So, nor the quorum that is kept in the nodes neither the quorum iscsi disk is not enough to start the cluster again. I want to use both disk majority and file share majority at the same time. Can I do this? Have you any other suggestion? Regards.

  • Hard Drive Compatibility with Motherboard

    - by Wesley
    Here are the current specs to put things in context: ECS P4VXASD2+ V5.0 Intel Pentium 4 Northwood 2.8 GHz 2x 512MB PC2100 DDR266 SDRAM Maxtor DiamondMax 10 250 GB PATA (IDE) HDD Gigabyte 52x CD-ROM NVIDIA TNT2 Pro 16 MB OKIA 300W ATX PSU USB bracket Modem PCI Before, I actually had a 300 GB hard drive installed. However, I read the FAQ for the motherboard and discovered that a maximum of 250 GB hard drive was supported. So I ended up finding the one listed above and put that in. However, upon booting up, I reset the BIOS to defaults and auto-detected all the drives installed. The 250 GB came up as something like 251.0 GB. I didn't think much about it until I tried to boot up a Windows XP installation disc. It booted up successfully and run for about a minute before the computer randomly rebooted. I've made sure that all the jumpers and settings are correct and everything has been installed correctly. I've tried running it without the addons and one stick of RAM but still the same thing. What else could be causing this problem?

  • How to verify TRIM/discard on encrypted swap?

    - by svarni
    I am using an encrypted swap partition via ecryptfs-setup-swap on my Ubuntu 13.04 computer using a SSD. I have manually set up trim for my ext4 root partition (simply by adding the "discard" option in /etc/fstab). I also manually ran fstrim on the root partition prior to booting and using dstat I saw that for a few seconds several GB/s of data have been written to the disk. That was presumably the effect of the trim command. These high writerates are reproducable by deleting huge files and have not occured before setting up trim, so I take them as evidence for working trim/discard. Manually enabling trim on my root partition has stopped the wearout of my precious new disk from 365 used reserved blocks (out of 6176 total) within three months down to 0 additional used reserved blocks within three additional months (data from SMART attributes). Because I want to minimize the wearout of my SSD I now would like to know whether my swap partition (which is encrypted using ecryptfs-setup-swap) also makes use of the trim/discard option. I tried sudo swapon -d -v /dev/mapper/cryptswap1 but did not receive particular information ("-v") about whether trim/discard ("-d") was applied. If unsupported, i would expect a message. Then I tried sudo dd if=/dev/sda6 count=1 BS=1M | xxd | less directly after booting and when no swapspace was used but I saw not only zeroes. I assume, when looking at freshly trimmed regions, the disk would send zeroes instead of reading random sectors (and according to some forums, (unencrypted) swap space is trimmed once upon boot). Long story short: Are there any ideas on how to test if trim is effectively used for my encrypted swap? And if not, any ideas on how to - at least manually, for once - trim the whole swap space? I wouldn't want to tinker with the partition itself, because I dont know if it needs to be reinitialized as (encrypted) swap - I dont want to be left with an unbootable system :)

  • CPU not working on a specific motherboard

    I'm making a computer for someone and I met a weird problem. The CPU that I have doesn't work on this motherboard. The CPU is an Intel Pentium D 925 and the motherboard is an ECS G41T-M6, which in theory should work together. The only thing reused is the power source(400W). When I start the computer, the fans start, and that's it. The BIOS doesn't boot. I tried my own power source (600W Corsair) and nothing. Removed the RAM, no warning. In desperation I tried the last thing, swaped my own CPU with this one (Core2Duo E7200). Lo and behold, it worked. Both. The Core2Duo worked on the ECS with the old power source and the RAM that I used in the first place, and the Pentium D worked on my Gigabyte G31M-ES2L. What I discovered was that the Pentium D didn't receive power on the ECS, because I tried running it without the cooler and it remained at room temperature. On a side note, I also removed the HDDs just in case. So, in conclusion, any ideas? I can't return it, and I can still use it to upgrade another PC, but I would really prefer not to buy another CPU if possible.

  • how can i move ext3 partition to the beginning of drive without losing data?

    - by Felipe Alvarez
    I have a 500GB external drive. It had two partitions, each around 250GB. I removed the first partition. I'd like to move the 2nd to the left, so it consumes 100% of the drive. How can this be accomplished without any GUI tools (CLI only)? fdisk Disk /dev/sdd: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc80b1f3d Device Boot Start End Blocks Id System /dev/sdd2 29374 60801 252445410 83 Linux parted Model: ST350032 0AS (scsi) Disk /dev/sdd: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 2 242GB 500GB 259GB primary ext3 type=83 dumpe2fs Filesystem volume name: extstar Last mounted on: <not available> Filesystem UUID: f0b1d2bc-08b8-4f6e-b1c6-c529024a777d Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal dir_index filetype needs_recovery sparse_super large_file Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 15808608 Block count: 63111168 Reserved block count: 0 Free blocks: 2449985 Free inodes: 15799302 First block: 0 Block size: 4096 Fragment size: 4096 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8208 Inode blocks per group: 513 Filesystem created: Mon Feb 15 08:07:01 2010 Last mount time: Fri May 21 19:31:30 2010 Last write time: Fri May 21 19:31:30 2010 Mount count: 5 Maximum mount count: 29 Last checked: Mon May 17 14:52:47 2010 Check interval: 15552000 (6 months) Next check after: Sat Nov 13 14:52:47 2010 Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 Default directory hash: half_md4 Directory Hash Seed: d0363517-c095-4f53-baa7-7428c02fbfc6 Journal backup: inode blocks Journal size: 128M

  • "could not find suitable fingerprints matched to available hardware" error

    - by Alex
    I have a thinkpad t61 with a UPEK fingerprint reader. I'm running ubuntu 9.10, with fprint installed. Everything works fine (I am able to swipe my fingerprint to authenticate any permission dialogues or "sudo" prompts successfully) except for actually logging onto my laptop when I boot up or end my session. I receive an error below the gnome login that says "Could not locate any suitable fingerprints matched to available hardware." What is causing this? here are the contents of /etc/pam.d/common-auth file # # /etc/pam.d/common-auth - authentication settings common to all services # # This file is included from other service-specific PAM config files, # and should contain a list of the authentication modules that define # the central authentication scheme for use on the system # (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the # traditional Unix authentication mechanisms. # # As of pam 1.0.1-6, this file is managed by pam-auth-update by default. # To take advantage of this, it is recommended that you configure any # local modules either before or after the default block, and use # pam-auth-update to manage selection of other modules. See # pam-auth-update(8) for details. # here are the per-package modules (the "Primary" block) auth sufficient pam_fprint.so auth [success=1 default=ignore] pam_unix.so nullok_secure # here's the fallback if no module succeeds auth requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around auth required pam_permit.so # and here are more per-package modules (the "Additional" block) auth optional pam_ecryptfs.so unwrap # end of pam-auth-update config #auth sufficient pam_fprint.so #auth required pam_unix.so nullok_secure

  • Port to use CentOS init.d functions

    - by jcalfee314
    What are good equivalent centos commands using functions in /etc/init.d/functions such as daemon to perform the following tasks? STARTCMD='start-stop-daemon --start --exec /usr/sbin/swapspace --quiet --pidfile /var/run/swapspace.pid -- -d -p' STOPCMD='start-stop-daemon --stop --oknodo --quiet --pidfile /var/run/swapspace.pid' It looks like daemon will work for the start command and killproc is used for the stop command. . /etc/init.d/functions pushd /usr/sbin daemon --pidfile /var/run/swapspace.pid /usr/sbin/swapspace . /etc/init.d/functions killproc -p $(cat /var/run/swapspace.pid) Would the --oknodo be needed in the CentOS env (the swap file is really only boot-time)? "oknodo - Return exit status 0 instead of 1 if no actions are (would be) taken." I don't see quiet in daemon or killproc, I can't imagine that it would matter though. The original start-stop-daemon for swapspace seems to have both -p and --pidfile (the same command). That must be an error. Did I miss anything? Any idea why daemon not create the pid file?

  • SSD as primary or secondary drive on a small Linux server?

    - by Alex Martelli
    I'm pensioning off my 10-years-old home server and replacing it with an Ubuntu 10.04 box. The two storage devices are a Western Digital Caviar Green 2.0TB HD and an Intel X25-M 34nm Gen 2 80GB SATA II 2.5inch SSD (the box has 8GB RAM and an i5 750, if it matters). I don't care much about boot times (since I don't plan to reboot all that often;-); the main frequent, performance-demanding task will be (re)building large open source C or C++ software packages from sources (as an open source contributor, I do that often). So, I thought I'd keep the SSD as the secondary drive and the HD as the primary one, using the SSD mostly for the files that can otherwise demand a lot of seeking (esp. in a parallel make). However, the friendly vendor (perhaps more experienced in Windows systems than in Linux ones) thinks the "normal" way to configure the machine would be with the SSD as the primary drive. I'm pretty rusty on configuring and tuning systems, so, I thought I'd better double check on SuperUser... thanks in advance for advice about this choice!

  • Is there a clean way to obtain exclusive access to a physical partition under Windows?

    - by zneak
    Hey guys, I'm trying, under Windows 7, to run a virtual machine with VMWare Player from an OS installed on a physical partition. However, when I boot the virtual machine, VMWare Player says that it couldn't access the physical drive for writing. This seems to be a generally acknowledged problem in the VMWare community, as Windows Vista introduced a compelling new security feature that makes it impossible to write to a raw drive without obtaining exclusive access to it first. I have googled the issue and found a few workarounds. However, the clean ones seem to only work on whole physical disks, and not on partitions. So I would be left with the dirty solution. In short, it meddles with the MBR to erase any trace of the partitions to use, makes Windows forget about them, then restores the MBR so we can launch the VM. I'm not sure I want to do that. Is there a way to let VMWare acquire exclusive access to the partition without requiring me to nuke it away? What I'd be looking for, I suppose, is a way to put just partitions offline instead of whole physical drives.
