• Strange File-Server I/O Spikes - What Is Causing This?

  - by CruftRemover

  I am currently having a problem with a small Linux server that is providing file-sharing services to four Windows 7 32-bit clients. The server is an AMD PhenomX3 with two Western Digital 10EADS (1TB) drives, attached to a Gigabyte GA-MA770T-UD3 mainboard and running Ubuntu Server 10.04.1 LTS. The client machines are taking an extremely long time to access/transfer data on the file server. Applications often become non-responsive while trying to open files located remotely, or one program attempting to open a file but having to wait will prevent other software from accessing network resources at all. Other examples include one image taking 20 seconds or more to open, and in one instance a user waited 110 seconds for Microsoft Word 2007 to save a document. I had initially thought the problem was network-related, but this appears not to be the case. All cables and switches have been tested (one cable was replaced) for verification. This was additionally confirmed when closing down all client machines and rebooting the server resulted in the hard-drive light staying on solid during the startup process. For the first 15 minutes during boot, logon and after logging on (with no client machines attached), the system displayed a load average of 4 or higher. Symptoms included waiting several minutes for the logon prompt to appear, and then several minutes for the password prompt to appear after typing in a user name. After logon, it also took upwards of 45 seconds for the 'smartctl' man page to appear after the command 'man smartctl' was issued. After 15 minutes of this behaviour, the load average dropped to around 0.02 and the machine behaved normally. I have also considered that the problem is hard-drive-related, however diagnostic programs reveal no drive problems. Western Digital DLG, Spinrite and SMARTUDM show no abnormal characteristics - the drives are in perfect health as far as the hardware is concerned. I have thus far been completely unable to track down the cause of this problem, so any help is greatly appreciated. Requested Information: Output of 'free' hxxp://pastebin.com/mfsJS8HS (stupid spam filter) The command 'hdparm -d /dev/sda1' reports: HDIO_GET_DMA failed: Inappropriate ioctl for device (the BIOS is set to AHCI - I probably should have mentioned that).

• How do I get rid of these "There is a problem with your tablet driver" messages?

  - by Adam Rosenfield

  Every time I run certain applications (including but not limited to GIMP, Microsoft Visual Studio, and 3DS Max), I get the following message box: There is a problem with your tablet driver. Please reboot your system. If the problem persists reinstall or update the driver. Obviously I've tried rebooting and that hasn't fixed anything. Secondly, I'm not running a tablet PC. This is just Windows XP SP3 running on a Dell Precision PWS490 desktop workstation. How do I get rid of these error messages? The applications still load normally after dismissing them, but they're rather annoying. Using Process Explorer, I got the call stack from the message box. It's coming from wintab32.dll. Here's the call stack when running GIMP (irrelevant frames omitted): ... 8 USER32.dll!MessageBoxA+0x45 9 wintab32.dll!WTMgrPacketHookExA+0x44a 10 libgdk-win32-2.0-0.dll!gdk_display_list_devices+0x37 ... So, does anyone know how I can get an updated version of wintab32.dll or have any other ideas? I've been keeping my system up to date with Windows Updates. The timestamp on wintab32.dll is 2007-03-30 17:38, and its MD5 sum is ffdc332007c9dc6dd346c8ac2b09a015.

• What is the solution to enable Dymo Turbo 400 Label Printer to work on Win 7 / 64-bit?

  - by mdpc

  It's Christmas time and time for printing labels for all those Christmas cards. I've upgraded to Windows 7 64-bit from XP. I've been unsuccessfully attempting to get the connected Dymo 400 Turbo label USB printer to work again. The latest manufacturer drivers have been successfully loaded and installed. The drivers are supposed to work on Windows 7/64-bit. The Win 7 system(s) in question are patched and up-to-date on that score. The Windows Update site responds with a driver when the USB cable is connected to this printer. The printer queue seems to be established correctly. What happens is that I submit a job to the printer (either using the DYMO s/w or not), it delays for a period of time, and then I get the message 'printing error'. Can't seem to locate the appropriate error in the new and improved event log. Several combinations of rebooting, re-installation and power cycling components fail to make the printer work. Sometimes during some type of reset it spits out the last thing to be submitted, but that seems intermittent. I have tried different USB cables and different USB (2.X) ports as well. I have run the Windows 7 troubleshooter it tries to fix the problem but alas it doesn't. Interestingly, trying the USB printer (and its associated manufacturer drivers and s/w) on another Windows 7 64-bit system has the identical failures noticed on the original system. I did not find anything on the manufacturers' site concerning this problem. The printer has no hardware problems or issues.

• Computer not finding hard drives on boot -sometimes-

  - by todd.pund

  Computer specs: Mobo: Gigabyte ultradurable 3 - GA-970A-UD3 Processor: First gen I7 3.2GHZ Ram: 8GB Kingston DDR3 1066 Video Card: EVGA NVidia GTX 460 1GB Hard Drive: 500MB 7200rpm x2 (can't remember brand, sorry I'm at work.) Last week my developer preview for Windows 8 ran out so I put my copy of windows 7 back on the computer. The computer at that point started suffering from frequent freezing and crashing. When I rebooted the computer sometimes it wouldn't find the system HD at all. When I looked at the post screen it seemed to show that it wasn't finding either of the HDs. Then yesterday when turning on the computer I just got GRUB as a message (not a GRUB prompt, just GRUB) I haven't had a dual boot of Linux for at least a year. I loaded windows 7 recovery console from the disk and ran: bootrec /fixboot bootrec /fixmbr Which did not help. At that point I just installed Ubuntu 13.04 over the windows 7 install and still received the GRUB post. I went into the BIOS and switched the Hard Drive priorities and then it loaded into Ubuntu fine. For several days everything was just hunky dory until I installed the Ubuntu version of Steam, install Portal and tried to run it. At that point the computer froze and after hard rebooting couldn't find the hard disks again. Then after restarting the system it loaded up fine again and no issues since. (I have not tried to launch portal again). My next thought is to remove the system hard drive and try to use the secondary as the master to see if the primary HD is bad. I'm sorry if this has been confusing, I'll answer any questions I can. Any thoughts?

• Dual hard drive Windows 7 system, modified the registry to get programs to install on second drive, now IE doesn't work

  - by paul

  I have a dual hard drive Windows 7 system, Windows is installed on an SSD (C:) and I modified the registry to try to force programs to install on second HDD drive (another letter). The registry edits are pretty simple, just a few keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion to change the drive letter. For the most part the system is very fast and works great, but IE doesn't work anymore. With IE10, it opens for a flash with a white window then closes. I tried installed IE11 which opens a white window for a few seconds, doesn't respond, then crashes. I've tried all the solutions I could find. This includes resetting the IE settings, "uninstalling" and re-installing IE, which is just turning it on and off in "Turn Windows Features on or off", copying the Program Files\Internet Explorer files onto both/either drives, changing the registry keys back to use C:, lots of rebooting, and safe mode. Nothing has worked. I don't see errors in the event viewer, but I might not know what to look for. Any ideas on how to get IE running? I don't need IE for daily browsing, I just need it for cross-browser testing on sites I build and on the rare occasion a page only works in IE. I don't really want to use a virtual machine, but would be ok with something standalone like tredosoft's, but I'm not aware of something like that for current versions of IE.

• How can I access user files on a disk moved from a Windows 7 machine to an XP machine?

  - by Fantius

  I moved the hard drive from one machine (Win 7) to another (XP) and now certain folders tell me "Access denied". I am logged in as an administrator. I had a different account on the other machine. Neither account authenticated to anything besides the local machine. The old machine is apparently dead, so I can't do anything in there like change permissions, etc. How can I access these files? Edit: After changing the ownerships of all the files and folders on the drive, I am getting a different error. And it is troubling me deeply. "xxx refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location." No change after rebooting. Any ideas? Surely the files are still there, right?

• Can a non-redundant RAID5 cause any serious problems (compared to RAID0)?

  - by leemes

  I used to have a three-disc RAID5 (mdadm) in my computer for personal media storage (music, videos, photos, programs, games, ...). It had three discs with 750 GB each, resulting in an array capacity of 1.5 TB. One day (one year ago), I needed one of those discs to install another operating system. I thought, I don't need the redundancy anymore since I backup the most important stuff (personal photos e.g.) on an external disc anyway. So I decided to remove one of the three discs without converting the RAID to RAID0 or even two separate discs, because I had no temporary storage (since one cannot simply convert the RAID5 to RAID0 AFAIK). So now, for about one year, I have a non-redundant RAID5 with 2 of 3 discs running. Sometimes, one of the discs has a defective contact at the power cable or something similar causing the drive to stop working temporarily (I don't know exactly what it is). Since it still works when rebooting the computer and in most cases by calling some mdadm commands, it wasn't that problematic. Note that the data is not very critical, since I still have a backup of the most important stuff. But in the last few weeks, one of the drives fails very frequently (every few hours), so it gets really annoying to manage this. My questions are: Is there any disadvantage (apart from the annoying management) of a non-redundant RAID5 (with one drive less than typical) over a RAID0? If I understand it correctly, both have no redundancy and the same capacity. On a temporary drive failure, I can restart the array in both cases, assuming that the drive itself still works after the failure. Can it happen that the drive contents alter on a drive failure, making the array inconsistent? If so, can I tell mdadm to check the array for failures (without a file system level checking tool)? Since the drive most probably only has a defective contact causing it to fail for a second only, can I tell mdadm to automatically restart the array, so I will not even notice the failure if no application wanted to access the file system during the failure?

• Windows 7 BSOD, safe mode working,

  - by mil0ck

  I need help getting my dualboot with Windows 7 and Ubuntu 12.04 to work, and since I'm not to experienced with computers I've been pretty dumb. Here's what I've done, quite shortend though: First removed a Ubuntu 10.04 partion, and replaced bootloader using EasyBCD Installed Ubuntu 12.04 on same partion as before Decided I need more space so I shrinked my C: partion (Windows partion) using Here, after rebooting my computer, I was stuck a grub rescue, when booting up the computer I fixed that by using SuperGrubDisk Rescatux and then using my Windows Vista install disk to repair the computer (computer is using Windows 7) I know re-installed Ubuntu 12.04 on the linux partion and got the GRUB-bootloader working Then, after using my computer for several hours, I installed beta drivers (version 304.79) for my GeForce GTS 240 and then rebooted my computer. At the first boot (after reboot) my computer just crashed, and here I am When trying to boot Windows 7 now I get a Blue Screen Of Death. I can though boot in to safe mode with everything working. I have uninstalled the beta drivers and installed the same one as before but still the same problem. I have tried all the commands in Bootrec.exe and none is working. I can't neither find an OS when using Bootrec.exe/ScanOs. I have also tried running: sfc/scannow and that comes out clean. Short: My harddrive and files seems to be intact but when booting I get bluescreen. I can though boot in to safemode with everything working. I need help Thanks to anyone who even took the time to read that. //mil0ck

• Issues connecting to HP ProCurve switches

  - by BriGuy

  We are having a very strange issue trying to connect to our infrastructure switches via SSH. When you first try connecting to them, the switches will prompt for the password - and then just sit there after it is entered. If you create a second SSH session to the switch (while letting the first one remain open and just sitting there) it will let you log right in. The switches are doing the same thing with RADIUS and local authentication. The other strange part to all of this, is that about 10 switches started doing it all at the same time. As far as actual configuration of the switches, nothing has changed. Occasionally, one switch will start working like normal, but then stop again. These are all HP ProCurve managed switches, but all different models/firmware. Some switches that are not working are using the same firmware as others that are working. UPDATE: 20130312 I am also seeing this same behavior when trying to use telnet. The first telnet session just hangs there, and the second telnet session will let me log in. Rebooting the switches seems to get them working, but I still have 5 production switches that cannot easily be rebooted because of their production roles. Is anyone aware of anything else that can be switched on/off that may reset the logon for remote management or something like that?

• User receives group membership error to terminal server even though has rights

  - by BlueToast

  http://www.hlrse.net/Qwerty/TSLoginMembership.png To log on to this remote computer, you must be granted the Allow log on through Terminal Services right. By default, members of the Remote Desktop Users group have this right. If you are not a member of the Remote Desktop Users group or another group that has this right, or if the Remote Desktop User group does not have this right, you must be granted this right manually. Only as of today a particular user began receiving this message for a second terminal server they use; otherwise, they have never had any problems authenticating into this server. We have no restrictions on simultaneous and multiple logins. On each terminal server, we have a group and security group like "_Users" locally in the Builtin\Remote Desktop Users group. For this particular user, on this particular terminal server we have locally given him Administrator, Remote Desktop Users, and Users membership; in AD we have given him DOMAIN\Administrator, Builtin\Remote Desktop Users, DOMAIN\_Users. It still gives us that error message. We gave him membership to another terminal server (random) by simply making him member of another DOMAIN\_Users group -- successfully able to login to that random terminal server. So, from scratch we created an AD account 'dummy' (username) with only Domain Users membership. Tried to login to this particular server, no success. So I added 'dummy' to DOMAIN\_Users group, and then was successfully able to login. Other users from this user's department are able to login to this particular server just fine as well. We checked the Security logs on this particular server, and while it is logging everything, the only thing it appears to not log are these failed login attempts from this particular user who receives this error message. We have tried rebooting the server, and the user is still receiving that error message.

• HSphere - Only sees Apache 2 Test Page after forced shutdown?

  - by Darkwoof

  Hi, I have a dedicated server running on a Dell PowerEdge 850 with CentOS 4.4 and HSphere 3.0 Patch 6 colocated at a datacenter. Last night my hosting company had to schedule a change in the power bar, and I gave the go ahead for them to shut down the server and bring it up when they are done. Since they do not have admin access to the machine, I suppose they did a forced shutdown. When the machine was brought up, I found that all my domains (and sub-domains) are now pointing to an "Apache 2 Test Page" instead of the pre-configured sites that were running prior to the shutdown. This apparently only affects the standard sites running on port 80 - my Webmin instance running at port 1000 is still accessible for example, as well as my HSphere control panel running at port 8080. I've checked the config settings using the HSphere UI for each of the sites, and didn't find anything wrong. I've also tried rebooting the server via SSH, which does not rectify the problem. I've previously done reboots with no issues; the sites would just come right back up when its done, but not this time. I'm guessing some configuration file got corrupted or overwritten this time? Anyone with experience with HSphere and can provide some advice on what's happened and how to solve it? Thanks. (I do not have an active support agreeement for HSphere since Parallels took over and increased the min. license to 200. I only had 25 license for use by family and friends.) Thanks in advance.

• Windows mounted network drives slow after upgrading switch

  - by Kver

  On our small business network our old 10/100 consumer grade switch gave up the ghost, and we replaced it with a proper business-grade gigabyte switch. After wiring it in our Linux and Mac users immediately got back to working off of network drives; But 2 of our 3 Windows 7 PCs have suddenly experienced a tremendous slowdown with mapped network drives; Windows will become stuck "discovering" a folder causing applications to freeze when trying to open files. It will instantly display and browse files, but the moment you try to open one the bug hits. To remedy this we have our users copying files to the desktop, but it can take a few minutes while windows is stuck "calculating" the time it will take to copy. These aren't big files, mostly excel sheets less than 500KB - these operations are instant on Linux and Mac. (The third Windows machine is having no issues) I've tried remapping the drives, mapping to different drive letters, rebooting, etc. I'm at a loss, because switches are mostly transparent, and it's only after the switch was replaced that the Windows PCs started acting up. What black-magic voodoo am I missing to make Windows work? Thank you.

• Windows Server 2003 (w/Exchange) move to new machine

  - by James Booker

  I have an ageing domain controller (the only one on a 10-pc network) which needs rebooting often. I have a Dell Poweredge 2850 server doing nothing, so I'd like to move the DC to that, but here's the catch - I don't have Win2k Server Std install media any more as it's been lost. I purchased "Easus Todo Backup Advanced Server" which claims to be able to recover to dissimilar metal, but it's not quite working (although I don't think it's the product's fault) I know the server and PERC RAID card are good because I installed Ubuntu on the logical drive (4 x 72GB disks RAID 5) no problems. I've booted frmo the Easus Todo backup CD (which is WinPE based) and recovered to the logical disk on the RAID (after installing driver inside the WinPE environment from a NAS drive) The problem is when I boot the server, I can get the OS selection menu, but any option results in a blank screen, with no errors. I figure this is probably because the driver wasn't installed on the old machine (which is IDE-based (i know, i know!) and doesn;t have a RAID controller) I've booted from the CD and copied the mraid35x.sys file to the c:\windows\system32\drivers folder on the recovered system, but it makes no difference. I made a boot.ini with rdisks 0-10 defined, and booting from each of these resulted in a file error (i.e. 'this isn't a real disk') - the only disk that gets any response (the blank screen) is multi(0)disk(0)rdisk(0)partition(1) which just gives me the blank black screen and no disk activity. Is there any way I can force the drvier to be installed on the source system (so i can do a full backup again), i've tried right-clicking the oemsetup.inf and clicking install, but it didn't actually do anything. I attempted to force it with the 'Add new hardware' wizard and forcing with the 'have disk' option but it still gave me no hardware to select. Also I've got an identical machine running WinXP which uses the PERC driver successfully (which was obviously done at install time) and the boot.ini settings are the same : multi(0)disk(0)rdisk(0)partition(1) Any ideas would be appreciated.

• No outbound internet connection after restarting CentOS 6.3

  - by wnstnsmth

  After restarting a headless CentOS 6.3 machine, it lost outbound internet connectivity, i.e. I can still connect to the server via SSH (ssh root@**.126.18.56), but stuff such as ping google.com gives google.com: unknown host, and yum list some_package gives a lot of network errors. This is what ifconfig gives: eth0 Link encap:Ethernet HWaddr 00:25:90:78:2D:5D inet addr:**.126.18.56 Bcast:**.126.18.255 Mask:255.255.255.0 inet6 addr: fe80::225:90ff:fe78:2d5d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:75594 errors:0 dropped:0 overruns:0 frame:0 TX packets:787 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7074741 (6.7 MiB) TX bytes:144391 (141.0 KiB) Interrupt:20 Memory:f7a00000-f7a20000 eth1 Link encap:Ethernet HWaddr 00:25:90:78:2D:5C UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:16 Memory:f7900000-f7920000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:504 (504.0 b) TX bytes:504 (504.0 b) I have absolutely no clue how to debug this, and I find it very strange since I can still connect via ssh. EDIT: Weirdly, /etc/resolv.conf does not contain any entries, or none that I can make sense of: # Generated by NetworkManager search sui-inter.net # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com So is it possible that rebooting the server erased that file? It worked before at least! And how do I solve this? By the way, pinging an IP address works.

• sporadic routing to another website when opening a common url

  - by user226098

  I have a strange problem in our office: Sometimes when opening a url from one of our projects random url in any browser not the right website shows up but some other website. In most of the cases it redirects to google.com with some parameters like https://www.google.de/?gfe_rd=cr&ei=krOOU8_kGcSKswadyYDQBw&gws_rd=ssl or just the ugly google 404 page). But today it remains on the origial url but shows up the the content of http://debug.netdna-cdn.com/. This happens about 1 time a week and for no apparent reason. Even stranger it only occurs on a single pc in the network. It now happens on two different computers in the network. Both use windows 8. The problem cannot be fixed by clearing the browser cache but by rebooting the pc or using ipconfig /flushdns. So I think it has something to do with the dns cache of the machine. But I have no idea what the reason is for this and how i can figure out how to solve it. Any ideas?

• How to copy VirtualBox VDI contents to a partition and dual boot the OS from it?

  - by Calmarius

  I'm a Linux user but I keep a compressed Windows XP ISO with me on a pen drive for the case I absolutely need Windows to do something. This works in VirtualBox most of the time. But now I want to play some games, so I would like to run the Windows image natively. My computer don't have CD drive so cannot just burn the ISO and make an install normally. What I trying to do is moving the installed Windows image to a physical NTFS partition on my HDD and set up GRUB to let me dual boot it. I found many tutorials that deal with making VDI to physical drive. But they assume I want to overwrite my entire drive. Moving the raw disk image with dd to the partition resulted in a corrupt partition. I also tried the VMDK trick to use that empty partition and install the Windows on it. Although the text mode phase of the installation finishes without problems, the VM won't work, either crashes and keeps rebooting or just immediately or freezes (depending on how I created the VMDK, with -rawdisk /dev/sda3 or -rawdisk /dev/sda -partition 3).

• Log Problem and bash script

  - by GvWorker

  Hello Guys, I have 11 Debian servers running on rackspace cloud hosting. All running VHCS2 for hosting management. 1 server is used for application and 10 are used for only smtp. My question is regarding smtp servers. Each server hosted 1 domain. My problem is when my client use smtp there's a log created in this directory /var/log/ but within 24 hours drives are full and server refuse all smtp connections. Then I deleted the logs and ran following command to check the disk space. df -h but it shows hdd still full and server is still refusing the smtp connections. Then I ran following command to see the truth du --max-depth=1 -h It shows the truth. The real disk space used. Then I rebooted the server and now server working fine. But after few hours same situation happened. Then I created the following script. #!/bin/sh rm -fr /var/log/* rm -fr /var/log/apache2/*.log rm -fr /var/log/apache2/*.log.* rm -fr /var/log/apache2/users/* rm -fr /var/log/apache2/backup/* reboot It worked for days but after that logs are again filling the hdd. Now I want the following solutions. If anybody can help me. When I delete files from server hdd will free up without rebooting Log should be in specific range. Like a specific size of file where old data overwrite with new data

• How do you permanently disable the 'This Connection is Untrusted' page on Firefox

  - by TheIronChef9

  I'm going insane. Can someone please help me to COMPLETELY DISABLE the 'This Connection is Untrusted' page on Firefox. Facts: I am running Firefox 23.0 on an Ubuntu machine (downloaded and installed ubuntu today) It is a work computer and I have to use my employer's proxy While visiting Webpages/webapps like Gmail or Google brings up the 'This Connection is Untrusted' page and I have to go through the whole tedious task of selecting 'I understand the Risks' and add Exceptions, etc. etc. The fact is, I don't care about the risks. I would rather this computer melt into the ground than have to see that page ever again. I want to dance naked in untrusted pages and not give a damn about the consequences. I just never want to see that page again. Ever. For some sites (eg. wikipedia), the css doesn't load and I end up seeing them in plain text. As a result these sites are completely useless. Wasted hours trying to solve this for stackoverflow.com. These issues happen on the Firefox on my Windows XP machine as well (also using the same proxy). I don't want to export/import certificates or create exceptions for every site that shows this bloody page. I just want this page gone. I don't want Firefox to tell me what's safe and what's not. Also, my system time and date are correct. I've also tried the lies on this page too with no good results. Edit: I've also tried the whole going into the Advance-Certificates-validation setup page and unchecked 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates' checkbox. Nothing happened even after restarting firefox or rebooting. I need help. Thanks.

• lamp -- edit PHP file but doesn't change web output -- including die()

  - by Reid W

  Server is standard Linux server on Amazon Web Services. Cent OS 5/Apache/PHP 5.3. No APC. It's worked fine for over a year, but now when I edit some but not all PHP files on the server using vi, the changes don't affect the web output. For example, I edit myfile.php and put a die() at the top, but when I load the page in my web browser, instead of the die() I see the content that would show up if the die() weren't there. svn updating the file in question doesn't help either. Files are on an Amazon EBS partition symlinked to /var/www/html. Just to reiterate -- this has worked fine for a long time. Restarting apache didn't help, nor did rebooting the server. What's weird is that it's just some of the files but not all. File ownership/permissions are the same for the "good" and "problem" files. I'm not a Linux newbie but am at a complete loss with this, and couldn't find anything on Google either. Any hints would be much appreciated!

• Install Peppermint OS three on Asus EeePC

  - by Kithoth

  I just had a new Asus EeePC R051CX. Out of the box, the installed OS is Ubuntu 12.04 LTS, but I am trying to install Peppermint OS three (as single boot). Problem. Once on live CD (well, live USB stick...), I'm in trouble in both following situations: Try Peppermint OS Live In this case, the first thing I get is a message reading The system is running in low-graphics mode Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself. I can solely press "return" to accept, then I have a list of 4 options to answer the question "What would you like to do?". But I simply can't do anything at this moment, except switching to console mode or rebooting (keyboard / mouse controls don't allow me to do anything else). Install Peppermint OS Something I really don't understand... it launches the Ubuntu Recovery Media (which was already installed when I received the device)! Also, it says in the bottom ERROR: This recovery media only functions on Ubuntu systems. All I can do is quit (that is, reboot). One last important thing that comes to my mind: this stick worked just fine on the other computers I've tried it on. I really hope someone could bring me the light, a friend of mine told me how cool this OS is for EeePCs. Don't want to give up! Thanks. Edit I finally could install Peppermint, but not by understanding why I couldn't do it the logical way. Instead, I reinstalled Ubuntu myself (erasing the factory one). Then, I could simply boot on my live USB and perform a fresh install of Peppermint. So, I still don't know how and why the mentioned problem occurred.

• Windows 7 Laptop Randomly Sleeping

  - by Josh Arenberg

  I'm running Windows 7 64-bit on a Lenovo laptop, and I have a problem wherein after I've put it to 'sleep' once, it will seemingly without any reason or warning go back to sleep every 10 to 15 minutes after that. Each time it wakes back up just fine, and you can happily continue on. However, 10 or 15 minutes later, it just drops out into sleep mode. I don't see any errors in the system logs. I don't think it's related to heat ( since it's not rebooting ). When I check the system event log, I can see where the machine goes to sleep, but it simply says "reason: application API", and doesn't indicate which app ( brilliant ). I don't see any errors from hardware or anything relating to sleep in the application log that would point to what is going on either. How can I find out which app is triggering this? EDIT: I confirmed that temperature wasn't the issue. I think it's important to keep in mind that this condition only happens after the first sleep. If I reboot, the problem goes away until I put it to sleep, after which it sleeps on it's own every few minutes. Is there no way to capture which app is calling the sleep routine?

• Recovering a broken NTFS filesystem?

  - by OverTheRainbow

  A much-needed Windows Update broke a Vista laptop that was running fine until then: After booting up, Windows displays "Please wait..." but it never goes anywhere. I waited for a couple of hours, there is a bit of disk activity, but it didn't work out in the end. I booted with the Vista DVD, chose "Repair your computer" which said that there was nothing wrong :-/ Next, I booted it up with a Linux USB keydrive, and ran Gparted 0.8.1 (which includes ntfsresize v2011.4.12AR.4 libntfs-3g) which displays a bunch of warnings for the NTFS partition where the Vista system is located such as: ntfs_mst_post_read_fixup: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument Record 16 has no FILE magic (0x0) Next, I ran ntfsfix /dev/sda2, which said: Mounting volume... OK Processing of $MFT and $MFTMirr completed successfully. NTFS volume version is 3.1. NTFS partition /dev/sda2 was processed successfully. Next, I rebooted Vista, which did a CHKDSK, before rebooting. But I'm still getting nowhere with "Please wait..." Before I copy the user's data to another host and reinstall Vista from a DVD, does someone know what I could try? Thank you. Edit: In case someone else has the same issue... After the BIOS, hit F8 and choose "Repair your computer", followed by "Toshiba HDD Recovery". In addition to a 1,5GB partition labelled "WinRE", the hard disk contains a second partition labeled "Data" from which the application will fetch a system image and reinstall it in the "Vista" partition. Make sure you copy your data out of the system partition before doing this.

• Question marks showing in ls of directory. IO errors too.

  - by jaymoo

  Has anyone seen this before? I've got a raid 5 mounted on my server and for whatever reason it started showing this: jason@box2:/mnt/raid1/cra$ ls -alh ls: cannot access e6eacc985fea729b2d5bc74078632738: Input/output error ls: cannot access 257ad35ee0b12a714530c30dccf9210f: Input/output error total 0 drwxr-xr-x 5 root root 123 2009-08-19 16:33 . drwxr-xr-x 3 root root 16 2009-08-14 17:15 .. ?????????? ? ? ? ? ? 257ad35ee0b12a714530c30dccf9210f drwxr-xr-x 3 root root 57 2009-08-19 16:58 9c89a78e93ae6738e01136db9153361b ?????????? ? ? ? ? ? e6eacc985fea729b2d5bc74078632738 The md5 strings are actual directory names and not part of the error. The question marks are odd, and any directory with a question mark throws an io error when you attempt to use/delete/etc it. I was unable to umount the drive due to "busy". Rebooting the server "fixed" it but it was throwing some raid errors on shutdown. I have configured two raid 5 arrays and both started doing this on random files. Both are using the following config: mkfs.xfs -l size=128m -d agcount=32 mount -t xfs -o noatime,logbufs=8 Nothing too fancy, but part of an optimized config for this box. We're not partitioning the drives and that was suggested as a possible issue. Could this be the culprit?

• Web Server slows down (ASP.NET)

  - by mfeingold

  below is a question I posted on stackoverflow . as suggested by Martin Clarke I also post it here. We have a really strange problem. One of the servers in the server farm becomes really slow. We see a number of timeouts in the logs and overall response time is not where it should be (and is on other servers in the farm). What is also strange is that it is not just the web app - Just logging into the server takes up to 1.5 min to show you the desktop. Once you are in, the system is as responsive as ever - unless you try to launch something, i.e. notepad - it takes another minute to launch and after launch it works fine. I checked a number of things - memory utilization is reasonable, CPU is below 15%, windows handles, event logs do not show anything. Recycling the aps.net process does not fix it - it still takes over a minute to log in. Rebooting the server helped, but now it started to slow down again. After a closer look we found out that Windows Temp directory is full of temp files - over 65k files. This is certainly something to take care of. But my question is could it be the root cause of the sluggishness, or there is still something else lurking in the shadows? Edit After more digging I am zeroing in on the issue related to the size of temp directories. This article: (see the original post this thing will not let me include a second link) describes something very similar. It still does not answer the question why the server is still slow even there is no activity.

• Remote Desktop svchost (networkservice) & lsa.exe high cpu usage, hangs on welcome screen

  - by Rohan1

  We have deployed an RDS Farm with 12 virtual RDS servers using Hyper V. Currently some users are not able to log on. After passing credentials to the connection broker, the session hangs on the "Welcome" screen. Using resource monitor we've seen that svchost (with the "networkservice" service) has a CPU usage of 50%, when viewing the wait chain on the process it displays that it's waiting for a lsa.exe to finish. We can't kill any of the users processes, even when trying with taskkill /f. Suspending lsa.exe did work but didn't have any effect. The networkservice also couldn't be restarted. Also, if this happens, the current users logged on to the RDS server can't be displayed. Task manager crashes when viewing the users, RDS service manager crashes when viewing the users (even remotely) and the cmd command "query session" doesn't work. No antivirus is installed on the RDS server. The only thing we can do is rebooting the server, which is not an option because of the fact that other users are in active sessions. Does anyone have ANY idea what's going on? We didn't encounter this in our pre-production setup.
