• Ubuntu 13.04 to 13.10: Filesystem check or mount failed [migrated]

  - by SamHuckaby

  I attempted to upgrade from Ubuntu 13.04 to 13.10 today, and mid upgrade the system started flaking out, and eventually locked up entirely. I was forced to restart the computer, and am now unable to get the computer to boot up at all. When I boot currently, it takes me to the GRUB menu, and I can choose to boot normally, or boot in an older version. I have tried several things, which I list below, but no matter what, when I try to finish booting into Ubuntu, I receive the following error: Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further errors will be ignored root@ubuntu-computername:~# I have fun fsck -f and everything appears correct, no errors are reported. and it passes all 5 checks. If I run fdisk -l then I get the following information: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes Disk identifier: 0x00010824 Device Boot Start End Blocks Id System /dev/sda1 * 2048 608456703 304227328 83 Linux /dev/sda2 608458750 625141759 8341505 5 Extended Partition 2 does not start on physical sector boundary. /dev/sda5 608458752 625141759 8341504 82 Linux swap / Solaris Disk /dev/sdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0fb4b7e8 Device Boot Start End Blocks Id System /dev/sdb1 8192 625139711 312565760 7 HPFS/NTFS/exFAT I am considering just installing a new OS on the other disk, that currently has nothing on it, and then just attempting to scrape my data off the old disk (thankfully I didn't encrypt the files). Really my question is this: Can I salvage this Ubuntu install, or should I give up and just reinstall?

• Any way to move Office Starter To-Go to a non-flash drive?

  - by Scott Bussinger

  Microsoft's Office Starter edition has an interesting option to create a portable version on a USB flash drive using the "Microsoft Office Starter To-Go Device Manager". This creates a portable version of the Word and Excel starter editions (limited versions of the normal applications that include ads). This would be great for use in Virtual Machines since it requires no registration and has a perpetual license. But I want to copy the files off of the flash drive and just store them in the VHD. The problem is that it appears when you try to run the office.exe executable from anywhere but the USB drive you get the error "Microsoft Office Starter To-Go cannot be launched because it is installed on an unsupported device." Any ideas what it is objecting to and is there a legal workaround for this? A limited but legal and portable version of Word and Excel is a great idea. But tying it specifically to a USB flash drive seems a bit odd. They don't seem to care how many of those flash drives you create so it's not clear what the restrictions are about.

• ESXi - change to thin - virtual disk filesize is the same

  - by sven

  running ESXi 5.5 here with a datastore on a single SSD. Now, I thought about changing to thin disks from thick and found that I could use a tool on the ESXi host to do that. However, the file size of the new created virtual disk is not changing. I run: vmkfstools -i loader.vmdk -d 'thin' thinloader.vmdk Destination disk format: VMFS thin-provisioned Cloning disk 'loader.vmdk'... Clone: 100% done. After that I compared the virtual disksizes: ls -la *.vmdk -rw------- 1 root root 32212254720 Jun 10 08:25 loader-flat.vmdk -rw------- 1 root root 467 May 21 17:04 loader.vmdk -rw------- 1 root root 32212254720 Jun 10 08:27 thinloader-flat.vmdk -rw------- 1 root root 520 Jun 10 08:33 thinloader.vmdk Stats on the original file: stat loader.vmdk File: loader.vmdk Size: 467 Blocks: 0 IO Block: 131072 regular file Device: 8bf64d175e27544ch/10085333178302026828d Inode: 419443780 Links: 1 Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2014-01-25 10:17:34.000000000 Modify: 2014-05-21 17:04:06.000000000 Change: 2014-05-21 17:04:06.000000000 and on the thin file: stat thinloader.vmdk File: thinloader.vmdk Size: 520 Blocks: 0 IO Block: 131072 regular file Device: 8bf64d175e27544ch/10085333178302026828d Inode: 432026692 Links: 1 Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2014-06-10 08:27:45.000000000 Modify: 2014-06-10 08:33:30.000000000 Change: 2014-06-10 08:33:30.000000000 Anyone an idea why the disk is not providing any more space (tried with multiple VM's already - all the same)?

• EEE PC dropbox server running 24/7

  - by microspino

  I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better). Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web. Print Server: I have Samsung SCX 4521F (fax/print/scan/copy), Samsung ML2010, HP Laser jet P1006, HP Color Laserjet CP1215, HP Office jet pro K8600, HP Design jet 500. All of them now are connected using little print servers and I want to get rid of them hooking everything to this mini server. The fax/print/scan/copy machine need to stay connected to a PC to make me able to use the software that comes with It. The mini server would save me on this too. Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server. I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously. I'd like to listen some advice from You. Best of all would be: If You have something similar running for a long time If You disagree with this hardware choice and If You would suggest some other device. If You see any issues with my printing setup Anything else ;) My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.

• Static Network configuration with bridge in CentOS 6.2

  - by Kyle

  I have a server with CentOS 6.2 installed, I want to use it as a VM host to run some windows installations for development purposes. I wanted to be able to directly RDP and serve websites from IIS on these windows server installations, so I figured I would set it up as bridged networking. I have been struggling with this all morning, usually the result being that when I brought up the bridge interface all network connectivity to the CentOS would go away, however, I think I finally have that all figured out. However, here's what happens. The eth0 and br0 interfaces are defined in /etc/sysconfig/network-scripts with ifcfg-eth0 and ifcfg-br0. I DO NOT have ifup or ifdown or any other files for these interfaces, I have not found if they are needed. I can login and use firefox to browse the web, however, running ifconfig reveals that my eth0 does not have an IPAddress, but the br0 does. I can actually RDP into the Windows installation, and browse the internet from there as well, but I cannot directly connect(via putty, vnc, nor viewing web pages) to the CentOS box. Any idea what's up? ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none IPADDR=192.168.1.20 GATEWAY=192.168.1.1 NETMASK=255.255.255.0 NETWORK=192.168.1.0 ONBOOT=yes BRIDGE=br0 ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=static DNS1=192.168.1.1 DNS2=8.8.8.8 GATEWAY=192.168.1.1 IPADDR=192.168.1.2 NETMAS=255.255.255.0 ONBOOT=yes I know some of the options are inconsistent (DNS and BOOTPROTO) because I tried changing those in the eth0 file to make it work, and the changes haven't adversly affected web browsing or the other functionality Thank you!

• Alternatives to ntbackup

  - by Chris J

  Is anyone aware of any good (for a given value of "good") alternatives to ntbackup? There's a few quirks with ntbackup that I still find odd, and occasionally (and for no obvious reason) ntbackup just doesn't back up - usually complaining about that the wrong tape's inserted even though it's been told to just use the tape that's in the drive regardless. I've experiemented with cygwin's tar and cpio and Win32 ports of these utilities, but I've not had any luck getting them to see the tape device (so if someone does use these utilities to write to a tape device, also be interested to know how). Essentially all I'm looking for is a reliable program that I can tell to back-up a list of locations to the tape, and not to care about anything like formatting tapes, or sticking volume labels on them (and conversely then makes it fairly straightforward to restore off as well). On the flip-side, I don't want something that will attempt to manage our tapes. Don't get me wrong here -- ntbackup can do the job, but its quirks are making look at possible alternatives. Any suggestions? If it's open source, even better.

• Why doesn't the Windows 7 volume mixer remember per-application levels for all applications?

  - by mdives

  If I have the device's master level set to 50, and then lower an application level to 25; Once I close that application and reopen it, the volume levels should persist. The master level should remain at 50 and the application's at 25. This does happen for most applications. However, for one in particular, Napster, it does not. I subscribe to Napster's streaming service. I use the Napster desktop application to connect to that service. Every time that I open the Napster app, I have to adjust the application's volume level down in the volume mixer. When I open the app again after closing it, I have to do the same thing, the volume mixer is not remembering the set level. In fact. The level is reset back to 50, the same level as the device's master level. Has anyone else experienced this, with Napster or any other application? Is there a solution or is this a known issue?

• Need to boot into chkdsk from USB on Windows netbook

  - by Gaz Davidson

  While attempting to install Ubuntu on a 32-bit Windows XP netbook, the partition resize operation failed due to inconsistencies in the NTFS filesystem (lesson learned: run chkdsk /f in Windows before trying to resize a partition in Linux). Now the installer only gives the option to replace Windows with Ubuntu, the partition can't be resized in gparted, which displays a red exclamation mark and an error log when you click it. To make matters worse, we're also unable to reboot into Windows to get at chkdsk. We get a BSoD when choosing any of the options (including the DOS recovery console thing). The netbook has no CD-ROM drive, contains no recovery image and our only connection to the Internet is via the hotspot on my mobile device. We don't have Windows recovery CDs, but we do have a USB flash drive. We have a 64-bit laptop running Ubuntu 12.04 and Windows 7 (both 64-bit). So, on to the question: Is anyone aware of a way to get into a DOS recovery console and run chkdsk from a USB disk drive, without having to pirate Windows XP or download hundreds and hundreds of megabytes of crap? If it was my device I'd just flatten it, but it isn't. Please help!

• How to route to a secondary interface on the same physical ethernet?

  - by sjose3612611

  INTERNET<->(wan)BRIDGED_DEVICE(lan)<->ETH_ROUTER<->LAN Problem: Need to access web server on BRIDGED_DEVICE's LAN from INTERNET via ROUTER (BRIDGED_DEVICE's web server cannot be accessed form INTERNET since it has no Public management IP). Cannot configure bridged device. It has a static IP on its LAN to which its web server binds. Attempt: Create a secondary/alias WAN Interface on ETH_ROUTER (e.g Primary: eth0.1 (for internet access) and Secondary: eth0.2 (for accessing web server on BRIDGED_DEVICE), (No VLANs). eth0.1 has a public IP; eth0.2 has a static private IP in the BRIDGED_DEVICE's subnet (e.g 10.0.X.Y). Iptables on ETH_ROUTER: Added a port forward (DNAT) from eth0.1 to eth0.2: iptables -t nat -I PREROUTING -i eth0.1 -p tcp --dport 80 -j DNAT --to-destination 10.0.X.Y iptables -t nat -I POSTROUTING -o eth0.2 -s 10.0.X.0/24 -j MASQUERADE Stateful firewall w/ overall drop policy on FORWARD chain, hence: iptables -I FORWARD -i eth0.1 -d 10.0.X.Y -p tcp --dport 80 -j ACCEPT Can ping from ETH_ROUTER to BRIDGED_DEVICE but unable to reach the web server from Internet. I see packet cont increasing for the DNAT rule but not sure where it disappears in the ETH_ROUTER after that. ETH_ROUTER is the only device that can be configured to achieve this. If familiar with this scenario, please suggest what I may be missing or doing wrong here or suggest techniques to debug?

• Ping server NETBIOS name returns wrong IP and "Destination host unreachable"

  - by music2myear

  Problem server is Windows 2008 R2 VM running on VMWare ESXi 4 host. Single network adapter manually assigned single IP address (192.168.1.11). When I ping the server from any other network computer, it returns 192.168.1.124 and "Destination host unreachable". Yesterday I found a second network adapter assigned to this server with an IP of 169.254... indicating it had no real valid IP. Using the MAC addresses I determined which adapter was not needed/not wanted, and removed it using VMWare systems. This is the network Printer Server and, understandably, nothing is printing right now. I've looked at the solutions here Why was my ping answered by a different IP address than the one pinged? and they aren't applicable to my situation for the following reasons: Output of arp -a on another computer returns the correct IP address (.1.11) assigned to the correct MAC address, the incorrect IP .1.124 is not listed, and the MAC of the network adapter I removed yesterday is not listed at all. I checked out the Microsoft KB article which listed pretty much my exact symptoms ( http://support.microsoft.com/kb/981953 ) and it says to check binding orders and look for hidden adapters. But there are no hidden adapters, and there is only one Network Adapter listed in the Binding Order list. Essentially, I can communicate from the server TO any other network device, but I cannot communicate from any other network device TO the server. Help! UPDATE: Solution found, see this solution for the details.

• Two parts: linux startup script to connect to bluetooth and cron to keep it connected

  - by D.R.

  I have a mini bluetooth keyboard and a Raspberry Pi running a Debian-based distro. I know the MAC address of the keyboard but for this question, let's just use AA:BB:CC:DD:EE:FF. Right now I have to have a wired keyboard connected as well as my bluetooth dongle for the mini-keyboard and on the wired keyboard, I have to run the following when the device boots up: sudo hidd --connect AA:BB:CC:DD:EE:FF If the device goes idle for too long, then the bluetooth disconnects and I have to pull out my wired keyboard and retype that same command. What I'm looking for it a way to have that command run at startup and a way to sense if it gets disconnected so that it will auto reconnect. The annoying thing is that they keyboard has to be in pairing mode (even though it has already been paired) when I run that command, otherwise it tells me the host is down. So perhaps the script needs to prevent it from disconnecting due to inactivity, otherwise I'll have to put it back in pairing mode to reconnect. So to recap: - A script to connect at startup (I can make sure to put the keyboard into pairing mode before turning it on) - A script to prevent it from disconnecting (maybe some sort of signal to send to it every 60 seconds or something?) Any help with this is greatly appreciated! StackOverflow is always the best place to find answers to weird questions! I've been searching long and hard for an answer, but finally had to resort to coming here! Thanks!

• Western Digitial My Book: Can't access the data on the drive

  - by Bryan Denny

  My girlfriend has this external hard drive by Western Digital called a My Book. When the external drive is connected, it does not show it as an accessible disk drive on the computer. However, it shows up fine in Device Manager: I can also see it in Disk Management, but the volume is not mapped to a drive letter, nor can I change the drive letter: It only gives me access to Delete Volume: I would rather not lose the data on the drive if possible. What can I do from here to get to the data? Things I've tried/know: Uninstall drivers and re-install them Device does the same thing when attach to either her Win7 laptop or my Win8 laptop I don't think there's an issue with the HDD itself. No clicking noises, etc. I ran Western Digital Data LifeGuard Diangostics (DLGDIAG) and the SMART Status was a "PASS", all of the SMART Disk Information looked fine. I haven't had the time to run the diag tests yet but I do not believe it's a mechanical issue. The hard drive is inside of an enclosure, I have not attempted to pry the drive out yet. How can I get Windows to properly detect this drive?

• Windows XP corrupts registry every several hours

  - by Ilya Kazakevich

  There is a Dell XPS 400 with Windows Media Center installer. It is installed on RAID (Intel Matrix Storage) which is built-in chipset south bridge. Raid has two 150 Gb WDC drivers connected as mirror. All drivers and updates are installed( sp3 and so on). A week ago PC changed its video mode to 256 colors (like VESA mode) and after several moments I got BSOD: c000021a: 0xc0000005 Doctor watson did not create dump although it is installed as default debugger. After reboot it said that config file is missing or corrupted. So, I boot to recovery console and found that registry file (config) is so small. I've replaced it with one from recovery point and windows booted sucessfully. But after about 3 hrs -- it has crashed again in the same wat! I look in event viewer: is said that Explorer.exe failed to open \global??\DLIAFS. I look in winobj, and found that it is a device. I made "deny from everyone" for this device ACL, and after several hours my windows crashed. I restored registry, boot again and there was no error about DLIAFS. I did full chkdsk and it did not found anything bad. But I found event about error paging to \Harddrive1\D. I do not have pagefile there, but I thought I should check my disk again. Unfortunatelly I cannt use smart tools for RAID, but I downloaded latest software from Intel (it can do the same things like RAID bios can but from windows). It verified my disks, found some errors, fix them, than I rebooted. And it crashed again. I am lost. What (except kernel debugging) could be done here? Thanks

• How do I boot [embedded] linux from sd card?

  I am hacking together a quick embedded linux system on a DM816x evm board. Previously I have been using TFTP and NFS to load my kernel and root filesystem to the board. I am now trying to switch over to loading everything from an SD card. I have my card partitioned such that uBoot and my kernel image are in one partition, and my rootFS in another partition. At power-on, Uboot starts correctly and successfully launches the kernel. However, the kernel is unable to mount the root file system. It appears that it doesn't recognize any SD (mmc) cards. It gives this error message. VFS: Cannot open root device "mmcblk0p2" or unknown-block(2,0) Please append a correct "root=" boot option; here are the available partitions: 1f00 256 mtdblock0 (driver?) 1f01 8 mtdblock1 (driver?) 1f02 2560 mtdblock2 (driver?) 1f03 1272 mtdblock3 (driver?) 1f04 2432 mtdblock4 (driver?) 1f05 128 mtdblock5 (driver?) 1f06 4352 mtdblock6 (driver?) 1f07 204928 mtdblock7 (driver?) 1f08 50304 mtdblock8 (driver?) Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) I feel like I'm missing something fundamental here. Why does it not recognize the root device I am trying to load from? Here is my uBoot boot script that is running: setenv bootargs console=ttyO2,115200n8 root=/dev/mmcblk0p2 rw mem=124M earlyprink vram=50M ti816xfb.vram=0:16M,1:16M,2:6M ip=off noinitrd;mmc init;fatload mmc 1 0x80009000 uImage;bootm 0x80009000

• 2008 Sever Randomly reboots.

  - by Jeff

  I'm out of ideas here. We have a 2008 Server that keeps rebooting 2-3 times a day at completely random times with an "Unexpected Shutdown" event. There are no Dumps, no events leading to it just like it loses power then comes back online. I ran a Diagnostic of the power supply and it has had continuous power for months. In addition, the temperature of the processors are maxing out at 40 degrees Celsius. Anyone have any ideas how to figure out why this is restarting all the time? This is a DMZed Web server so it doesn't do too much process wise. Here are the specs: Host Name: ~~~ OS Name: Microsoft Windows Server 2008 R2 Standard OS Version: 6.1.7600 N/A Build 7600 OS Manufacturer: Microsoft Corporation OS Configuration: Standalone Server OS Build Type: Multiprocessor Free Registered Owner: Windows User Registered Organization: Product ID: ~~~ Original Install Date: 5/27/2010, 4:25:47 PM System Boot Time: 2/14/2011, 5:35:01 PM System Manufacturer: HP System Model: ProLiant DL380 G6 System Type: x64-based PC Processor(s): 1 Processor(s) Installed.

• Reducing video mode switching during Linux boot

  - by Zack

  When I boot up my desktop computer, which only has Linux on it, the video mode and/or console font gets switched four times: When GRUB starts, it switches from 80x25 text to a graphical mode so it can draw a pretty background behind its menu; GRUB then goes back to 80x25 text after I pick something from the menu; When the KMS driver for my video card loads, it switches to a much higher-resolution text mode (I don't know if this is a hardware text mode or not); Finally X starts and it goes graphics and stays that way. I think this last switch does not change the resolution of the video mode, only the graphicalness. I'd like to get rid of as many of these mode switches as possible. Ideally, when GRUB takes over from the BIOS it would go directly to the same high-resolution text mode that the KMS driver selects, and the display would stay in that mode till X starts and brings up graphics. I am under the impression that this is possible by mucking with the kernel command line and/or the GRUB console module load parameters, but I don't know the details. GRUB 1.98+20100706, kernel 2.6.32.15 using Nouveau video drivers. Distro is Debian unstable. Please no answers that involve recompiling anything or cobbling together bleeding-edge kernel/driver combinations, I don't care enough about this to go to that much trouble. EDIT: Tobu suggests setting GRUB_GFXMODE to the full pixel resolution of the monitor, and GRUB_GFXPAYLOAD_LINUX=keep to avoid the mode switch after the menu goes away. This does part of what I want, but winds up being worse overall. There's no mode switch after the menu, but there's still a painfully-slow screen repaint (I should probably just give up on GRUB's gfxmode, it's waaaay too slow at 1920x1200). More seriously, there's now a double mode switch when nouveaufb loads, along with fun-looking error messages in dmesg [ 5.923798] [drm] nouveau 0000:02:00.0: allocated 1920x1200 fb: 0x40250000, bo ffff8801ba5f4600 [ 5.923802] fb: conflicting fb hw usage nouveaufb vs EFI VGA - removing generic driver [ 5.923821] [drm] nouveau 0000:02:00.0: PFIFO_INTR 0x00000010 - Ch 1 ("PFIFO_INTR" message repeats 400+ times) [ 5.925609] Console: switching to colour dummy device 80x25 [ 5.925802] Console: switching to colour frame buffer device 240x75

• Constant beeping

  - by Bogi Juul Peterson

  My computer has a problem with beeping. I'll first tell you how it started: One night I decided to watch a cartoon, and I took some water and food with me to eat while I watch. I fell asleep and when I woke up I had spilled water all over my keyboard. I didn't react quickly, because it went unnoticed for about 1 and a half hours. When I noticed, I quickly put my laptop on a radiator to try to dry it. When I turned the computer on there was a constant beeping sound. I didn't know what caused it, and I'm still not sure, but I think it has something to do with the USB hub. If I let the computer stand for some hours without any USB connections, it's fine, but when I put any kind of USB device in, it starts beeping. The laptop keyboard doesn't work so I have to have some kind of USB device connected to use the computer. The beeping is going on while I'm writing this and it makes my computer lag so much that it can make delays from the keyboard be from 1 second to 10 seconds. I need this computer because I don't have the money to buy a new one, and I have to use this computer for homework and games. The beeping is constant, with less than a second between beeps. If anyone has a solution, please help.

• 100% iowait + drive faults in dmesg

  - by w00t

  Hi, I have a server on which resides a fairly visited web app. It has a raid1 of 2 HDDs, 64MB Buffer, 7200 RPM. Today it started throwing out errors like: kernel: ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen kernel: ata2.00: cmd b0/d0:01:00:4f:c2/00:00:00:00:00/00 tag 0 pio 512 in kernel: res 40/00:00:00:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) kernel: ata2.00: status: { DRDY } kernel: ata2: hard resetting link kernel: ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) kernel: ata2.00: max_sectors limited to 256 for NCQ kernel: ata2.00: max_sectors limited to 256 for NCQ kernel: ata2.00: configured for UDMA/133 kernel: sd 1:0:0:0: timing out command, waited 7s kernel: ata2: EH complete kernel: SCSI device sda: 976773168 512-byte hdwr sectors (500108 MB) kernel: sda: Write Protect is off kernel: SCSI device sda: drive cache: write back All day long it has been in load higher than 10-15.

I do have one process that is constantly writing with 1-2megs but what the hell.. 100% iowait?

• Windows PE network setup

  - by microchasm

  I'm walking through the following step-by-step guide for deploying Windows 7 via AIK: http://technet.microsoft.com/en-us/library/dd349348%28WS.10%29.aspx On step 4 (Capturing the Installation onto a Network Share), I run into a bit of a snag: attempting to connect to a network drive repeatedly fails. I'm using/deploying Dell Optiplex 380 64 bit machines, and the network cards seem to be really wonky. On the machine that I'm using to run AIK etc, the network driver wasn't found automatically. I had to manually go in and install the driver (which was found on the OEM installation media). I've since copied this to the USB key that I'm using for the Autounattend.xml so its handy. I think that because of this, the PE environment doesn't or can't instantiate the network device. Is there a way to install/configure the network device through the command prompt in PE? If not, I read about adding in the answer file path(s) to drivers, but if I did it this way, would I have to start the process all over again (i.e. create new Autounattend.xml with the PnPcustomizations path included, re-run the installation on the reference machine, install all the applications, re-make the PE iso, reboot into new PE iso)? Any shortcuts, direction, or advice would be appreciated. Thanks!

• Authenticate VNC session with ConsolKit?

  - by lori

  I have a linux machine running Fedora 16 in a cupboard. It has no screen or keyboard. I connect to it using a combination of vnc and ssh. Recently, after an update, I have had issues with authentication on the machine. If I vnc to it, the kde desktop pops up an error dialog every few minutes saying Authorization failed. Failed to obtain authentication. If I plug in a USB drive it fails to mount, Dolphin reports an authentication issue again. I have had limited success finding the solution. AFAICT, it is an issue with ConsoleKit deeming me to be a non-local user so it prevents authentication. This is the output from ck-list-sessions: $ ck-list-sessions Session5: unix-user = '1000' realname = 'steve' seat = 'Seat6' session-type = '' active = FALSE x11-display = ':1' x11-display-device = '' display-device = '' remote-host-name = '' is-local = FALSE on-since = '2012-09-16T08:07:03.137011Z' login-session-id = '1' I have tried to update my .vnc/xstartup script to include ck-launch-session as follows: $ cat ~/.vnc/xstartup #!/bin/sh exec ck-launch-session vncconfig -iconic & unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS export XKL_XMODMAP_DISABLE=1 OS=`uname -s` if [ $OS = 'Linux' ]; then case "$WINDOWMANAGER" in *gnome*) if [ -e /etc/SuSE-release ]; then PATH=$PATH:/opt/gnome/bin export PATH fi ;; esac fi if [ -x /etc/X11/xinit/xinitrc ]; then exec ck-launch-session /etc/X11/xinit/xinitrc fi if [ -f /etc/X11/xinit/xinitrc ]; then exec ck-launch-session sh /etc/X11/xinit/xinitrc fi [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources exec ck-launch-session xsetroot -solid grey exec ck-launch-session xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & exec ck-launch-session twm & This has not helped. How can I either authenticate myself to ConsoleKit, or trick it into believing I am a local user?

• Millions of files in php's tmp error - how to delete?

  - by Jonatan Littke

  Hey. I've got a tmp-folder with 14 million php session files in my home directory. At least that's what I think it is, it's not like I could ls it or anything. How can I empty this folder? I've tried using find with the -exec rm {} \; commands but that didn't work. ls 'sess_0*' | xargs rm did neither. I'm currently running rm -rf tmp but after two hours the folder appears to be the same size. REFERENCE INFO: I suddenly encountered an error where SESSIONS could no longer be written to disk: [Mon Apr 19 19:58:32 2010] [warn] mod_fcgid: stderr: PHP Warning: Unknown: open(/var/www/clients/client1/web1/tmp/sess_8e12742b62aa68a3f9476ec80222bbfb, O_RDWR) failed: No space left on device (28) in Unknown on line 0 [Mon Apr 19 19:58:32 2010] [warn] mod_fcgid: stderr: PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/www/clients/client1/web1/tmp) in Unknown on line 0 I ran: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/md0 457G 126G 308G 29% / tmpfs 1.8G 0 1.8G 0% /lib/init/rw udev 10M 664K 9.4M 7% /dev tmpfs 1.8G 0 1.8G 0% /dev/shm But as you can see, the disk isn't full. So I had a look in the syslog which says the following 20 times per second: kernel: [19570794.361241] EXT3-fs warning (device md0): ext3_dx_add_entry: Directory index full! This led me thinking to a full folder, obviously, but since my web folder only has 60k files (having counted them), I guessed it was the tmp folder (the local one, for this instance of php) that messed things up. Some commands I ran: $ sudo ls sess_a* | xargs rm -f bash: /usr/bin/sudo: Argument list too long find . -exec rm {} \; rm: cannot remove directory '.' find: cannot fork: Cannot allocate memory I'm running Debian Lenny, php5, ISPConfig, SuEXEC and Fast-CGI.
