  • Exchange server not serving mobile devices - how to troubleshoot?

    - by chickeninabiscuit
    Our exchange server has suddenly stopped serving mobile devices. Attempts to connect result in our ActiveSync server returning HTTP 500. It is serving outlook clients fine. Our server is Windows 2003 SBS 6.5 SP2 There are no abnormal events in the system log. I ran the "Exchange ActiveSync with AutoDiscover" at https://www.testexchangeconnectivity.com/ I've notice an abnormality in the exchange properties, Log File Directory shows: Access denied.

  • configure squid3 to set up a web proxy in ubuntu12.04

    - by Gnijuohz
    I am in a LAN and have to use a proxy given to access the web in a very limited way. I can't even use google, github.com or SE sites. However I can use ssh to log into a server, which I have root access so basically I can do anything I want with it. So I was thinking that maybe I could use that server as a proxy so I can visit sites through it. I tested it using ssh -vT [email protected] which gave a proper response. And In my computer I can't do this. Also I tried downloading something from the gun.org using wget, which can't be done in my computer too. And it succeeded on that server. I don't know if that's enough to say that this server have full access to the Internet. But I assumed so and I installed squid3 on it. After trying some while, I failed to get it working. I got this after I run squid3 -k parse 2012/07/06 21:45:18| Processing Configuration File: /etc/squid3/squid.conf (depth 0) 2012/07/06 21:45:18| Processing: acl manager proto cache_object 2012/07/06 21:45:18| Processing: acl localhost src 127.0.0.1/32 ::1 2012/07/06 21:45:18| Processing: acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 2012/07/06 21:45:18| Processing: acl localnet src 10.1.0.0/16 # RFC1918 possible internal network 2012/07/06 21:45:18| Processing: acl SSL_ports port 443 2012/07/06 21:45:18| Processing: acl Safe_ports port 80 # http 2012/07/06 21:45:18| Processing: acl Safe_ports port 21 # ftp 2012/07/06 21:45:18| Processing: acl Safe_ports port 443 # https 2012/07/06 21:45:18| Processing: acl Safe_ports port 70 # gopher 2012/07/06 21:45:18| Processing: acl Safe_ports port 210 # wais 2012/07/06 21:45:18| Processing: acl Safe_ports port 1025-65535 # unregistered ports 2012/07/06 21:45:18| Processing: acl Safe_ports port 280 # http-mgmt 2012/07/06 21:45:18| Processing: acl Safe_ports port 488 # gss-http 2012/07/06 21:45:18| Processing: acl Safe_ports port 591 # filemaker 2012/07/06 21:45:18| Processing: acl Safe_ports port 777 # multiling http 2012/07/06 21:45:18| Processing: acl CONNECT method CONNECT 2012/07/06 21:45:18| Processing: http_port 3128 transparent vhost vport 2012/07/06 21:45:18| Starting Authentication on port [::]:3128 2012/07/06 21:45:18| Disabling Authentication on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Disabling IPv6 on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Processing: cache_mem 1000 MB 2012/07/06 21:45:18| Processing: cache_swap_low 90 2012/07/06 21:45:18| Processing: coredump_dir /var/spool/squid3 2012/07/06 21:45:18| Processing: refresh_pattern ^ftp: 1440 20% 10080 2012/07/06 21:45:18| Processing: refresh_pattern ^gopher: 1440 0% 1440 2012/07/06 21:45:18| Processing: refresh_pattern -i (/cgi-bin/|?) 0 0% 0 2012/07/06 21:45:18| Processing: refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880 2012/07/06 21:45:18| Processing: refresh_pattern . 0 20% 4320 2012/07/06 21:45:18| Processing: ipcache_high 95 2012/07/06 21:45:18| Processing: http_access allow all I deleted some allow and deny rules and added http_access allow all so that all the request would be allowed.

  • Windows 7 x64 "upgrade" repair fails

    - by Polynomial
    I've been running into issues with Windows Update, which I can't seem to fix. The hotfixes don't work, nor does the Windows update readyness tool, or the manual SP1 upgrade. I get various esoteric errors which nobody seems to have a fix for. Looks like some of the update cache is corrupt and digital signatures seem to be broken on some packages / Windows Update components. Long story short, I have discovered the only option is to do a repair operation on the OS, to repair everything. It's so corrupt that only a complete replacement will fix it. According to various sources (including MSKB) one can perform a repair by running an in-place upgrade. I've got the Windows 7 Ultimate retail disc, which I've inserted into my machine. I ran setup.exe and went through in the following order: Install now Go online to get latest updates (I've also tried not getting updates) Wait for updates to be downloaded Select Windows 7 Ultimate (x64 architecture) and click next Accept the T&Cs, click next Click Upgrade At this point it spends a minute on the "checking compatibility" screen, after which I get the following error: The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue. You can’t upgrade 64-bit Windows to a 32-bit version of Windows. To upgrade, obtain a 64-bit version of the installation disc, or go online to see how to install Windows 7 and keep your files and settings. 32-bit Windows cannot be upgraded to a 64-bit version of Windows. To upgrade, obtain a 32-bit version of the Windows installation disc. It also mentions a warning about potential conflicts with a storage driver and VS2010, but that doesn't seem to be the blocking issue. My currently installed version of Windows is Ultimate 64-bit (absolutely sure of this) and the disc is definitely a x86 / x64 combined Ultimate retail disc. There seem to be a few people who have run into this (e.g. this question), but I've not seen any answers. I've checked the event viewer, but can't spot anything in there that's related. Any idea how I can get this working? P.S: Just to pre-empt the inevitable "are you suuuuuuuuuuuuure it's x64 Ultimate?" questions:

  • ZFS/Btrfs/LVM2-like storage with advanced features on Linux?

    - by Easter Sunshine
    I have 3 identical internal 7200 RPM SATA hard disk drives on a Linux machine. I'm looking for a storage set-up that will give me all of this: Different data sets (filesystems or subtrees) can have different RAID levels so I can choose performance, space overhead, and risk trade-offs differently for different data sets while having a few number of physical disks (very important data can be 3xRAID1, important data can be 3xRAID5, unimportant reproducible data can be 3xRAID0). If each data set has an explicit size or size limit, then the ability to grow and shrink the size limit (offline if need be) Avoid out-of-kernel modules R/W or read-only COW snapshots. If it's a block-level snapshots, the filesystem should be synced and quiesced during a snapshot. Ability to add physical disks and then grow/redistribute RAID1, RAID5, and RAID0 volumes to take advantage of the new spindle and make sure no spindle is hotter than the rest (e.g., in NetApp, growing a RAID-DP raid group by a few disks will not balance the I/O across them without an explicit redistribution) Not required but nice-to-haves: Transparent compression, per-file or subtree. Even better if, like NetApps, analyzes the data first for compressibility and only compresses compressible data Deduplication that doesn't have huge performance penalties or require obscene amounts of memory (NetApp does scheduled deduplication on weekends, which is good) Resistance to silent data corruption like ZFS (this is not required because I have never seen ZFS report any data corruption on these specific disks) Storage tiering, either automatic (based on caching rules) or user-defined rules (yes, I have all-identical disks now but this will let me add a read/write SSD cache in the future). If it's user-defined rules, these rules should have the ability to promote to SSD on a file level and not a block level. Space-efficient packing of small files I tried ZFS on Linux but the limitations were: Upgrading is additional work because the package is in an external repository and is tied to specific kernel versions; it is not integrated with the package manager Write IOPS does not scale with number of devices in a raidz vdev. Cannot add disks to raidz vdevs Cannot have select data on RAID0 to reduce overhead and improve performance without additional physical disks or giving ZFS a single partition of the disks ext4 on LVM2 looks like an option except I can't tell whether I can shrink, extend, and redistribute onto new spindles RAID-type logical volumes (of course, I can experiment with LVM on a bunch of files). As far as I can tell, it doesn't have any of the nice-to-haves so I was wondering if there is something better out there. I did look at LVM dangers and caveats but then again, no system is perfect.

  • backup of KVM VM's running on Ubuntu 12.4.1 precise edition from a remote machine

    - by Dr. Death
    I am creating a library API which will take the backup of all the VM's running on KVM hypervisor. My VM's can be of any type. I am taking this backup from a remote machine and need to put the backup at remote server. I have KVM, Libvirt installed on my system. Some of my VM's are LVM based and some are normal VM's running on KVM. I research and found out an excellent perl script for taking the backup http://pof.eslack.org/2010/12/23/best-solution-to-fully-backup-kvm-virtual-machines/ but since I am developing this library in C++ I cannot use it however it has given me a good understanding of how it will work. One thing I didnot able to sort out is if my VM's are not created using virt-manager or are created using any other tool them virsh system list command does not give them in the list of running VM's however they are running perfectly on my KVM server. Is there a way to list these VM's in my system list anyhow? secondly, when I am taking backup from the remote machine I am getting out of my ssh mode as soon as my libvirt command finishes and for every command I need to ssh again, Is there a way that I do not need to ssh each and every time? I have already used the rsa key for ssh but when once my command finishes my control moves to the remote machine again and try to find out my source VM location in remote machine's local drives which in turn fails it. here is the main problem I am facing. also for the LVM based VM I am able to take the live backup but for non LVM based my machines are getting suspended and not been able to take the live backup. Since my library will work on the remote machine only I might not know the VM's configruation on the KVM server. so need to make it consistent for all the VM's. Please share any thing related to this issue so that I may be able to take the live backup of the non lvm vm's also. I'll update my working and any research findings time to time to all of you. Thanks in advance for your suggestions in these regards.

  • Deleting windows.edb and unchecking Indexing service lead to hard drive file records swapping

    - by linni
    I followed the instructions listed here:http://www.mydigitallife.info/2007/09/18/turn-off-and-disable-search-indexing-service-in-windows-xp/ to free up space on hard drive by deleting the windows.edb indexing file... I also stopped windows search service as mentioned in the comments following the article. In addition to unchecking the "Allow Indexing Service to index this disk for fast file searching" check box on the properties dialog for the C:\ drive, I did the same for two usb connected hard drives (J:\ and I:\ ). I'm not sure why I did that, thought it might shrink the windows.edb file so I wouldn't have to delete it (which sounded a bit risky in my ears at the time). The file of course didn't shrink so I ended up deleting it and freeing up over 3 GB of space, yeehaw. However, as soon as I had done this I could not access the usb connected hard drives anymore. The error I got was "I:\photos is not accessible" "The file or directory is corrupted and unreadable" when I tried to open the photos directory on I:\ Here is where I enter the twilight zone... I try disconnecting I:\ usb hard drive. But XP shows me that instead J:\ drive has disconnected and I:\ is still there. So I disconnect both drives and restart the computer. I then connect one drive, but it lists up the contents of the other drive on root level. I tried connecting the drives vice versa and the same thing happens. I try taking one of the hard drives to another computer and when I connect it there it lists up not its own contents but the contents of the other hard drive and gives the same error as above when I try and access any of the folders (even folders on the root that have the same name as folders on the other drive (e.g. J:\photos and I:\photos)??? And no, this is not a me mixing up my drive letters. Computer Manager - Disk management shows the same result as explorer: The drive size is correct (one is 500GB, the other is 640GB) but the drive name is of the opposite drive, as long as the contents. Also, one drive was full of data and the other almost empty but they incorrectly show their free space status of the other drive. Somehow the usb drives seem to have switched file tables, file records, boot records or something, extremely weird! Even weirder, if I try and create a text file or folder on this drive, it works fine, accessing them, saving, whatever, all good, but accessing any other data on the drive gives me an error. Does anyone have a clue what is going on and more importantly, how I can restore the correct folder listings to access my family photos ??? cheers, linni

  • Messages stuck in SMTP queue - Exchange 2003

    - by Diav
    I need your help people ;-) I have a problem with messages coming into our Exchange Server and ones going out through it. Basically, the messages are stuck in the SMTP queue. A message will come into the server, I can see it listed under "Exchange System Manager", but if you list the properties of the message queue it says something like 00:10 SMTP Message queued for local delivery 00:10 SMTP Message delivered locally to [email protected] 00:10 SMTP Message scheduled to retry local delivery 00:11 SMTP Message delivered locally to [email protected] 00:11 SMTP Message scheduled to retry local delivery etc etc For outgoing message list looks like this: 10:55 SMTP: Message Submitted to Advanced Queuing 10:55 SMTP: Started Message Submission to Advanced Queue 10:55 SMTP: Message Submitted to Categorizer 10:55 SMTP: Message Categorized and Queued for Routing 10:55 SMTP: Message Routed nad Queued for Remote Delivery And the end - since then status didn't change, message is in queue, I am forcing connection from time to time but without an effect. I checked connection with smarthost (used telnet for that) and everything seems to work correctly, so the problem is probably on exchange side. I am using Exchange Server 2003 running on Small Business Server 2003. I don't have any antivirus installed on server. Remaining free space on each partition is over 3Gb, on partition with data bases - it is over 12Gb. All was working good and without problems since 2005, problems started in half of this june - messages started going out and being stuck almost randomly (I don't see a pattern yet, some are going out, some are not, some are going after several hours). I don't know what to do, what to check more, so please, any ideas? Best regards, D. edit Priv1.edb has 14,5GB and priv1.stm 2,6GB - together those files have more than 16GB - can it be the reason? If yes, then what? Indeed, I haven't thought that it can have something in common with my problem, but several users reported recent problems with Outlook Web Access - they can log in, they see the list of their mails, but they can't see the content of their emails. Although when they are connecting with Outlook 2003/2007 - there is no such problem, only with OWA there is. edit2 So,.. It works now, and I have to admit that I am not really sure what the problem was (hope it won't come back). What have I done: Cleaned up some mailboxes to reduce size of them Dismounted Information Store Defragmentated data base files ( I used eseutil: c:\program files\exchsrvr\bin eseutil /d g:\data base\Exchsrvr\MDBDATA\priv1.edb ) Mounted Information Store back ..and before I managed to do anything else - my queue started moving, elements which were kept there already for days - started moving and after few minutes everything was sent, both, outside and locally. But: priv1.edb is still big (13 884 203 008), priv1.stm as well (2 447 384 576), so this is probably not the issue of size of the file. And if not this, so what was that? And if that was issue of size of the file, then soon it will repeat - is there something I can do to avoid it ?

  • SQL Server 2008 R2 upgrade fails on upgrade rule check

    - by Tim
    I'm trying to upgrade an evaluation instance of SQL Server 2008 to a fully licensed instance of SQL Server 2008 R2. I made it most of the way through the installer, but I'm getting stopped at the Upgrade Rules page - the SQL Server Analysis Services Upgrade Service Functional Check is failing. The specific error I get: Rule "SQL Server Analysis Services Upgrade Service Functional Check" failed. The current instance of the SQL Server Analysis Services service cannot be upgraded because the Analysis Services service is disabled or not online. Please start the service and then run the upgrade rules check again. Simple enough - just need to start the service. Here's where it gets troublesome. When I open Services and go to start the SQL Server Analysis Services (MSSQLSERVER) service, it provides me the following message: The SQL Server Analysis Services (MSSQLSERVER) service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs. Trying from the command line as Administrator yields: PS C:\Windows\System32 net start MSSQLServerOLAPService The SQL Server Analysis Services (MSSQLSERVER) service is starting... The SQL Server Analysis Services (MSSQLSERVER) service could not be started. The service did not report an error. More help is available by typing NET HELPMSG 3534. I've tried changing the logon setting of this service to Administrator, a user with admin privileges, and both the Local System and Network Service accounts - nothing works. In addition, when I look at the service through the SQL Server Configuration Manager (also run as Administrator), attempting to change the logon setting for the service results in the message: The server threw an exception. [0x80010105] I have no need for analysis services themselves - all I need is for this one service to be running long enough to do the R2 upgrade, then it can shut down again. Any thoughts on how to get the Analysis Services service running? Update: Checking the event log, I found an error logged to the Application log from the MSSQLServerOLAPService. It has event ID 0, task category (289), and says: The service cannot be started: XML parsing failed at line 1, column 4: Unrecognized input signature.

  • What "pieces" are needed in order to set up a cluster of physical servers?

    - by Chris Dutrow
    Background: Currently, we use Rackspace cloud servers. We have no intention to stop using them, but would like to look into setting up a cluster of physical servers (probably desktop computers in the $400 range with 8gb memory each) to offset some of our load and work as a secondary, more powerful, less reliable system. To put things in perspective, we can buy comparable desktop computers for the same price as we pay in one month to rent them on Rackspace Cloud. I understand that this is generally a dumb idea. However, in this particular instance, the server cluster is needed for its computation power. It is not mission-critical, it does not host a consumer-facing website, and if it goes down for a day or two, its not really a problem. Currently, we have access to business class verizon fios. If I understand correctly, we can get at least 25 dedicated IP addresses with this service, this should be enough. Requirements: Each server runs Linux Centos 6.3 Some of the servers run Python and execute processes from a task queue (Redis or RabbitMQ) Some of the servers are capable of serving static files and Python driven REST APIs Some of the servers host a Cassandra database cluster One or more of the servers are a Redis database servers One or more of the servers are PostgreSQL servers Questions: What kind of router or switch is needed? We would like the computers to be able to communicate effectively with each other via internal IP addresses. This is especially important for communicating with servers hosting Redis that need to be able to respond to requests very quickly. Are there special switches or routers that need to be used to connect the servers together? Are Desktop computers ok for this? We have found that we are mostly RAM-bottle necked, I understand that some servers have highly superior CPUs, but I'm not sure we need CPU power as much as we need RAM, which is cheap in Desktop computers. Will we have problems with the WIFI cards in the desktops or any other unexpected hardware limitation? What tools should be used to "image" the servers. For example, when we get an installation right for a Redis server or Cassandra node, are there tools that come with Linux Centos 6.3 to image the server to a USB drive or something like that? Or do we need to use some other software for this? What other things are we missing that we should be concerned about? Thanks so much!

  • Xubuntu login hangs after Cancel Button click

    - by akester
    I'm running Xubuntu 12.04 (I installed using the alternative installer.) running in Virtaulbox 4.1.20 My issue is with the login screen (lightdm-gtk-greeter). It usually runs just fine, and allows users to log in and out but it will hang if the user presses the cancel button. The interface is still working (ie, shutdown menu is still available, I can switch to a different tty) but the username or password field (depending on when the button is hit) is disabled. Restarting lightdm will reset the screen, but the problem still exists. The issue is only with the cancel button. The login, session, and language buttons/menus as well as the accessibility and shutdown menu appear to work normally. I've modified some of the config files for lighdm-gtk-greeter, specifically /etc/lightdm/lighdm-gtk-greeter.conf to change the background image and /etc/lightdm/lightdm.conf to disable the user list. I did not check to see if the error existed before the changes took place. The changes have been restored the default settings but the problem persists. Here is the output of /var/log/lightdm/lightdm.log when the screen is hung: [+0.00s] DEBUG: Logging to /var/log/lightdm/lightdm.log [+0.00s] DEBUG: Starting Light Display Manager 1.2.1, UID=0 PID=2072 [+0.00s] DEBUG: Loaded configuration from /etc/lightdm/lightdm.conf [+0.00s] DEBUG: Using D-Bus name org.freedesktop.DisplayManager [+0.00s] DEBUG: Registered seat module xlocal [+0.00s] DEBUG: Registered seat module xremote [+0.00s] DEBUG: Adding default seat [+0.00s] DEBUG: Starting seat [+0.00s] DEBUG: Starting new display for greeter [+0.00s] DEBUG: Starting local X display [+0.02s] DEBUG: Using VT 7 [+0.02s] DEBUG: Activating VT 7 [+0.03s] DEBUG: Logging to /var/log/lightdm/x-0.log [+0.04s] DEBUG: Writing X server authority to /var/run/lightdm/root/:0 [+0.04s] DEBUG: Launching X Server [+0.05s] DEBUG: Launching process 2078: /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch [+0.05s] DEBUG: Waiting for ready signal from X server :0 [+0.05s] DEBUG: Acquired bus name org.freedesktop.DisplayManager [+0.05s] DEBUG: Registering seat with bus path /org/freedesktop/DisplayManager/Seat0 [+0.28s] DEBUG: Got signal 10 from process 2078 [+0.28s] DEBUG: Got signal from X server :0 [+0.28s] DEBUG: Connecting to XServer :0 [+0.29s] DEBUG: Starting greeter [+0.29s] DEBUG: Started session 2082 with service 'lightdm', username 'lightdm' [+0.36s] DEBUG: Session 2082 authentication complete with return value 0: Success [+0.36s] DEBUG: Greeter authorized [+0.36s] DEBUG: Logging to /var/log/lightdm/x-0-greeter.log [+0.36s] DEBUG: Session 2082 running command /usr/lib/lightdm/lightdm-greeter-session /usr/sbin/lightdm-gtk-greeter [+0.58s] DEBUG: Greeter connected version=1.2.1 [+0.58s] DEBUG: Greeter connected, display is ready [+0.58s] DEBUG: New display ready, switching to it [+0.58s] DEBUG: Activating VT 7 [+1.04s] DEBUG: Greeter start authentication for andrew [+1.04s] DEBUG: Started session 2137 with service 'lightdm', username 'andrew' [+1.09s] DEBUG: Session 2137 got 1 message(s) from PAM [+1.09s] DEBUG: Prompt greeter with 1 message(s) [+17.24s] DEBUG: Cancel authentication [+17.24s] DEBUG: Session 2137: Sending SIGTERM

  • Weird random application hang problem

    - by haridsv
    I am trying to understand an application hang problem that started up lately on my windows xp system. The system runs fine for days (sometimes) without ever shutting down or putting it to sleep, but the problem first shows up as one of the apps hanging. The application's UI stops responding or one or more background threads hang, so even though the GUI is responding, it is not doing anything (e.g., in VirtualDub's case, the UI responds fine, but the job doesn't progress and I won't even be able to abort it). The weirdness part comes from the fact that if I try to kill such an app, the program that is used to kill it goes into the same mode (i.e, that hangs instead of the original). E.g., if I use Process Explorer to kill it, the original program exits, but procexp now hangs. If I use another instance of procexp to kill the one that is hanging, this repeats, so there is always at least one program hanging in that state. This is not specific to procexp, I tried the native task manager and even the "End Process" dialog from windows explorer that shows up when you try to close a non-responsive GUI (in this case, the explorer itself hangs). The only program that didn't hang after the kill, is the command line taskkill. However, in this case, explorer hangs instead of taskkill. Also, once this problem starts manifesting, it soon ends up freezing the whole system to the extent that even a clean shutdown is not possible, so I have learned to reboot as soon as I notice this problem, however this is very inconvenient, as I often have encoding batch jobs going on which can't continue the job after the restart. The longer I leave the system running after seeing this problem, the more applications get into this state. I have tried to do a repair install but that didn't make any difference. I also uninstalled some of the newer installs, but again no difference. I tried to search online, but got inundating results for generic hang and crash related problems. Though I couldn't notice any pattern, it seems as though the problem is more frequent if I have some video encoding going on at that time. I had the system running for days when I only do browsing and internet audio/video chat before I decide to start encoding something and the problem starts to show up. I am not too sure if it is the encoding program that first hangs, though I almost always noticed that too hanging (like the VirtualDub stopping to make progress). I also had to reboot 3 times on one day when I was heavily experimenting with encoding. I would appreciate any help in narrowing down this problem and save me the trouble of reinstalling. I don't especially want to loose my gotd installs.

  • Logitech Optical Mouse Frozen In Middle of Windows XP Pro Screen

    - by Code Sherpa
    I have a Logitech Optical Mouse/Keyboard. I have been using them just fine with the system drivers for almost a year now. I recently updated my Kaspersky software and rebooted. Now the mouse is frozen in the middle of my screen. I am not able to login to the Windows XP Pro box that has the frozen mouse (because i can't work the mouse) but am able to remote desktop to this computer. Things I know / have tried: When I boot on the problem computer, I am able to use the keyboard, but not the mouse. I have installed the latest version of Logitech's SetPoint (with the updated drivers) on the problem computer (via remote desktop) and that didn't seem to matter. I bought new batteries for the mouse and that didn't matter. I have tried the mouse/keyboard on another computer and the mouse works just fine there. My suspicion is that the Kaspersky install has overwritten a driver of some sort. Things I have not done (and would appreciate detailed steps if you feel this is the way to go): 1) Uninstalled all the mouse drivers on the machine and reboot. Then, reinstall. Note: When I get to the Device Manager I don't see an option for Human Interface Devices (where the mouse device is). Here are my options: Computer, Disk Drives, DVD/CD-Rom drives, Floppy controllers, IDE ATA/ATAPI, Imaging devices, Network Adapters, Other devices, Ports, Processors, Sound, video, and gaming, System devices, USB controllers. Also, I should point out that Video Controller is the only thing under Other devices and it has a yellow exclamation mark. The same is true for all the items under Universal Serial Bus controllers. I think this means I have to update my BIOS but, since my mouse was working just fine without doing that, I don't think that is my problem. So, how do I get to my Mouse Device? 2) Update my BIOS. Note: As pointed out above, I don't think this matters as my mouse was working just fine under my computer's current BIOS version. Thanks for your help.

  • Installing OpenLDAP on Fedora 12: ldap_bind: Invalid credentials (49)

    - by Alpha Hydrae
    I've been trying to set up the OpenLDAP installed by default on Fedora 12, very unsuccessfully. My ultimate goal is to use LDAP authentication for user login and Apache, using the OpenLDAP server running on the same machine. The server is running, but the error I always get when I try to use ldapsearch or ldapadd is: ldap_bind: Invalid credentials (49) I've been following these tutorials, but none of them helped me: http://www.howtoforge.com/openldap_fedora7 http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/s1-ldap-quickstart.html http://www.howtoforge.com/linux_ldap_authentication http://docs.fedoraproject.org/deployment-guide/f12/en-US/html/s1-ldap-pam.html http://www.openldap.org/doc/admin24/quickstart.html First, some components were already installed, and I installed these with yum: yum install openldap-servers openldap-devel Then, I created a basic slapd.conf file in /etc/openldap: database bdb suffix "dc=sniejana-sandbox,dc=com" rootdn "cn=root,dc=sniejana-sandbox,dc=com" rootpw {SSHA}cxdz55ygPu4T3ykg7dgu+L0VRvsFSeom directory /var/lib/ldap/sniejana-sandbox.com I obtained the rootpw with this command: slappasswd -s changeme I also created the /var/lib/ldap/sniejana-sandbox.com directory and made sure the entire contents of /var/lib/ldap were owned by the ldap user. I found two ldap.conf files, one in /etc and one in /etc/openldap. I don't know which is the right one. If I understood correctly, this file is to configure the client. I put this in both: HOST localhost BASE dc=sniejana-sandbox,dc=com I then ran the server with: service slapd start It said OK. Most of the tutorials above say to use the command ldapsearch -D "cn=Manager,dc=my-domain,dc=com" -W to ensure that everything's working. When I execute this command, a password prompt appears, and after entering the password, I get the error. ldapsearch -D "cn=root,dc=sniejana-sandbox,dc=com" -W Enter LDAP password: ldap_bind: Invalid credentials (49) The same thing happens when trying to use ldapadd. I tried with an encrypted and unencrypted password in slapd.conf, it doesn't change anything. Adding a -x for simple authentication doesn't change anything either. netstat -ap confirms the server is listening: tcp 0 0 *:ldap *:* LISTEN 4148/slapd tcp 0 0 *:ldap *:* LISTEN 4148/slapd ps -ef|grep slapd confirms the process is running: ldap 4148 1 0 15:22 ? 00:00:00 /usr/sbin/slapd -h ldap:/// -u ldap Running slaptest procudes config file testing succeeded. I read somewhere that the command ldapsearch -x -b '' -s base '(objectclass=*)' namingContext can confirm the server is running. It appears to work: # extended LDIF # # LDAPv3 # base <> with scope baseObject # filter: (objectclass=*) # requesting: namingContext # # dn: # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 I'm running out of ideas. Am I missing something obvious?

  • Can someone explain RAID-0 in plain English?

    - by Edward Tanguay
    I've heard about and read about RAID throughout the years and understand it theoretically as a way to help e.g. server PCs reduce the chance of data loss, but now I am buying a new PC which I want to be as fast as possible and have learned that having two drives can considerably increase the perceived performance of your machine. In the question Recommendations for hard drive performance boost, the author says he is going to RAID-0 two 7200 RPM drives together. What does this mean in practical terms for me with Windows 7 installed, e.g. can I buy two drives, go into the device manager and "raid-0 them together"? I am not a network administrator or a hardware guy, I'm just a developer who is going to have a computer store build me a super fast machine next week. I can read the wikipedia page on RAID but it is just way too many trees and not enough forest to help me build a faster PC: RAID-0: "Striped set without parity" or "Striping". Provides improved performance and additional storage but no redundancy or fault tolerance. Because there is no redundancy, this level is not actually a Redundant Array of Inexpensive Disks, i.e. not true RAID. However, because of the similarities to RAID (especially the need for a controller to distribute data across multiple disks), simple strip sets are normally referred to as RAID 0. Any disk failure destroys the array, which has greater consequences with more disks in the array (at a minimum, catastrophic data loss is twice as severe compared to single drives without RAID). A single disk failure destroys the entire array because when data is written to a RAID 0 drive, the data is broken into fragments. The number of fragments is dictated by the number of disks in the array. The fragments are written to their respective disks simultaneously on the same sector. This allows smaller sections of the entire chunk of data to be read off the drive in parallel, increasing bandwidth. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss. So in plain English, how can "RAID-0" help me build a faster Windows-7 PC that I am going to order next week?

  • Windows 7 fails to install on KVM with qemu

    - by kief_morris
    I'm trying to install Windows 7 on a virtual machine on my 64 bit Ubuntu Karmic box. I get to the point of selecting my language settings and clicking 'install now', but a short while later I get a blue screen of death. I've tried a few variations, including using the 32 bit (fails very quickly). The virt-install command I've tried includes this: sudo virt-install --connect qemu:///system -n ksm-win7 -r 2048 \ --disk path=/home/kief/VM-Images/ksm-win7.qcow2,size=50 \ -c /var/Software/Windows7/Full/64bit/SW_DVD5_SA_Win_Ent_7_64BIT_English_Full_MLF_X15-70749.ISO \ --vnc --os-type windows --os-variant vista --hvm The limited info I could find suggested that 'vista' should work as the --os-variant, I haven't found any values specific to windows 7. Here's my blue screen: I've found very little by Googling, so I'm guessing this isn't a case of KVM simply not supporting Windows 7. Thanks for any help. Update: I have been able to successfully create a Windows 7 VM using the graphical "Virtual Machine Manager" app, although I don't really understand the cause of the problem with the VM created with virt-install. Comparing the configuration files under /etc/libvirt/qemu provides some clues, although I don't know enough to interpret them properly. The interesting differences in the two VM configurations are: --- win7-virt-install.xml +++ win7-vmm.xml -<domain type='qemu'> +<domain type='kvm'> @@ -21 +21 @@ - <emulator>/usr/bin/qemu-system-x86_64</emulator> + <emulator>/usr/bin/kvm</emulator> @@ -23 +23 @@ - <source file='/home/kief/VM-Images/ksm-win7.qcow2'/> + <source file='/var/lib/libvirt/images/ksm-win7x64.img'/> I'm not sure if this means the working VM is not using qemu at all, or if there is some other difference in the way it's used with kvm. Update2: So I've answered my own question (mostly) below. A KVM VM needs to use KVM's own CPU emulation rather than qemu's in order for me to get Windows 7 installed. I'm not sure whether there is something that can be done to get it working on a qemu-emulation CPU, or whether a newer version will support it. But at least it is possible to get it running on a KVM VM.

  • Deleting windows.edb and unchecking Indexing service lead to hard drive file records swapping

    - by linni
    I followed the instructions listed here:http://www.mydigitallife.info/2007/09/18/turn-off-and-disable-search-indexing-service-in-windows-xp/ to free up space on hard drive by deleting the windows.edb indexing file... I also stopped windows search service as mentioned in the comments following the article. In addition to unchecking the "Allow Indexing Service to index this disk for fast file searching" check box on the properties dialog for the C:\ drive, I did the same for two usb connected hard drives (J:\ and I:\ ). I'm not sure why I did that, thought it might shrink the windows.edb file so I wouldn't have to delete it (which sounded a bit risky in my ears at the time). The file of course didn't shrink so I ended up deleting it and freeing up over 3 GB of space, yeehaw. However, as soon as I had done this I could not access the usb connected hard drives anymore. The error I got was "I:\photos is not accessible" "The file or directory is corrupted and unreadable" when I tried to open the photos directory on I:\ Here is where I enter the twilight zone... I try disconnecting I:\ usb hard drive. But XP shows me that instead J:\ drive has disconnected and I:\ is still there. So I disconnect both drives and restart the computer. I then connect one drive, but it lists up the contents of the other drive on root level. I tried connecting the drives vice versa and the same thing happens. I try taking one of the hard drives to another computer and when I connect it there it lists up not its own contents but the contents of the other hard drive and gives the same error as above when I try and access any of the folders (even folders on the root that have the same name as folders on the other drive (e.g. J:\photos and I:\photos)??? And no, this is not a me mixing up my drive letters. Computer Manager - Disk management shows the same result as explorer: The drive size is correct (one is 500GB, the other is 640GB) but the drive name is of the opposite drive, as long as the contents. Also, one drive was full of data and the other almost empty but they incorrectly show their free space status of the other drive. Somehow the usb drives seem to have switched file tables, file records, boot records or something, extremely weird! Even weirder, if I try and create a text file or folder on this drive, it works fine, accessing them, saving, whatever, all good, but accessing any other data on the drive gives me an error. Does anyone have a clue what is going on and more importantly, how I can restore the correct folder listings to access my family photos ??? cheers, linni

  • My server is slower than the average user's computer, should I still offload Access queries to SQL Server? [closed]

    - by andrewb
    Possible Duplicate: How do you do Load Testing and Capacity Planning for Databases I have a database set up with MS Access 2007 front ends and an SQL Server 2005 back end. At the moment, all the queries are saved in the front end as I've only recently moved to an SQL Server backend. I'm wondering how much of those queries I should save as stored procedures/views on SQL Server. About the system The number of concurrent users is only a handful, though it could be as high as 25 at one time (very unlikely). The average computer has an Intel i3-2120 CPU running at 3.3 GHz, which gets a PassMark score of 3,987, whilst the server has an Intel Xeon E5335 running at 2.0 GHz, which gets a PassMark score of 2,637. Always an awkward situation when an i3 outperforms a Xeon... though the i3 is from Q1 2011 and the Xeon is Q2 2009. There is potential for a server upgrade in the future, though it wouldn't come easy. I'm inclined to move the queries to the back end, as they are beginning to take noticeable time and I figure that is a better way of doing things. I like the idea of throwing everything at the server, then pushing for a server upgrade. It makes more sense in my mind to be upgrading one server rather than 30 PCs. Or am I being overzealous? Why my question isn't a duplicate It seems that my question has been misinterpreted and labelled a duplicate of quite a different question, one about testing and capacity planning. I'll try explain how my question is very different from the linked question. The crux of my question is something like "Even though my server is technically slower, is it better to have it doing more of the queries?" There's two ways that people could have answered this: I agree the server is going to be slower, but the extra benefits of such and such (like the less Access the better) means you should move most to the server anyway. (OR no it doesn't outweigh the benefit, keep them in Access) Actually the server will be faster because of such and such. I'm hoping that people out there could provide some answers like this, and the question in the dupe link doesn't really provide either of these answers. Ok sure, I suppose I could do extensive performance testing to compare Access queries running on a local machine to SQL Server queries running on the server, but that sounds like a very hard task (particularly performance testing of access) compared to someone giving some quick general guidance, and again, my question is looking for a lot more than immediate performance benefit.

  • SSH_ORIGINAL_ENVIRONMENT error with snow leopard client to a gitosis server on debian

    I have a server running gitosis (installed from the package manager) on debian lenny. I am able to perform all operations from my linux mint laptop, but from my Mac running an up-to-date Snow Leopard gives me the following error: mica@waste Desktop$ git clone [email protected]:Poems.git Initialized empty Git repository in /Users/micas/Desktop/Poems/.git/ ERROR:gitosis.serve.main:Repository read access denied fatal: The remote end hung up unexpectedly mica@waste Desktop$ ssh -v [email protected] OpenSSH_5.2p1, OpenSSL 0.9.8l 5 Nov 2009 debug1: Reading configuration data /etc/ssh_config debug1: Applying options for * debug1: Connecting to 192.168.0.156 [192.168.0.156] port 22. debug1: Connection established. debug1: identity file /Users/micas/.ssh/identity type -1 debug1: identity file /Users/micas/.ssh/id_rsa type 1 debug1: identity file /Users/micas/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5 debug1: match: OpenSSH_5.1p1 Debian-5 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.2 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '192.168.0.156' is known and matches the RSA host key. debug1: Found key in /Users/mica/.ssh/known_hosts:5 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Offering public key: /Users/mica/.ssh/id_rsa debug1: Remote: Forced command: gitosis-serve mica@waste debug1: Remote: Port forwarding disabled. debug1: Remote: X11 forwarding disabled. debug1: Remote: Agent forwarding disabled. debug1: Remote: Pty allocation disabled. debug1: Server accepts key: pkalg ssh-rsa blen 277 debug1: Remote: Forced command: gitosis-serve micas@waste debug1: Remote: Port forwarding disabled. debug1: Remote: X11 forwarding disabled. debug1: Remote: Agent forwarding disabled. debug1: Remote: Pty allocation disabled. debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Requesting [email protected] debug1: Entering interactive session. debug1: Requesting authentication agent forwarding.

  • Trust Bluetooth 4.0 and Bluetooth Headset

    - by Seregwethrin
    Firstly, I'm writing this after 5 hours of nonstop struggle to make it work, so I searched into the deepest websites from Google, and tried many things. I have Trust Bluetooth 4.0 USB adapter (link) Samsung HM1500 Bluetooth Headset Windows 7 64-bit Desktop PC Facts Nothing wrong with the headset. (it works, tested on a phone and a laptop. Problem is all about bluetooth dongle and its driver.) Trust BT adapter can send and receive files even without any driver. I can pair successfully without any driver too. In Headset's Properties, Services tab, Handsfree and Headset services are checked. Problem When I pair with my BT headset, I cannot see it as a sound playback device. Also when I double-click the headset device icon in Bluetooth Devices, in laptop: it opens a connection window where I can connect and disconnect to that device - perfect! in desktop: it opens the properties window, even though Handsfree and Headset services are checked (I check them explicitly, in laptop they came as already checked) - Problem! Unsuccessful driver installations The driver on the Trust's website says "Error 1606 Could not access Network Location" on start, so it doesn't get installed. The driver on Broadcom (link) is being closed with Windows's that classic "has stopped working" error on validation step, so it doesn't get installed too. (Those tests made more than once) Successful installation In the Win64 folder of Trust's driver from their website, if I install through "BTW.msi", it doesn't give me Error 1606 and it gets installed. Then the problem: When I try to start bluetooth from start menu (or it gets started at Windows startup), an error popup says: "BtBalloon.dll is missing..." so it doesn't start. I found BBalloon.dll in the driver folder, I renamed it to BtBalloon.dll, moved into Windows/system32 and Windows/SysWOW64 folders, and it seems working. Or maybe it gets closed behind the scenes. The bluetooth icon is there with or without this driver since Windows has it. Bluetooth Peripheral Device First it didn't get installed from Windows Update. After, I showed the driver folder path in Device Manager and pressed "Explore in this location". Surprisingly, it's being found as "Handsfree" driver. Now even I uninstall the drivers, it still can see the Handsfree. But still, no playback device. Any ideas to guide me? I'm out of ideas.

  • Windows 7 laptop constantly dropping internet connection

    - by Corbin Holbert
    I have scoured the web for an answer and failed to find one. I am using a Toshiba Satellite laptop running Windows 7 64-Bit. I have the computer connected via Wifi. Now, I am no beginner with the Internet, or anything related to computers, as I have grown up teaching everyone around me how to use computers, and went to college for IT. Everything on my network works flawlessly at all times, except for this evil laptop. The worst part is that I fixed this once before a few years back and recently had to replace the hard drive and re-install the OS, but cannot for the life of me remember what I did to make this problem go away. I am in my browser, connected to the Internet. I click a link. Suddenly no internet access. All I do is click down on the WiFi connection in the task bar, disconnect and reconnect immediately. Internet is back the moment I hit "connect." I have read many people had the same issues as I am having, but they all had triggers or other network issues. I have no trigger (this happens literally five to six times per minute no matter what I am doing) and I have no problems with my router, modem, or any other devices or computers on said network. As I am a web designer, and like to test my work live at every turn- this is going to result in this laptop being in pieces if I can't get it fixed soon. If more info is needed, let me know and I will provide. Thanks for any help offered! EDIT: Network Card: Realtek RTL8188CE Wireless LAN 802.11n PCI-E NIC Network state reads as "No Internet Access" when the problem first occurs, then magically I have Internet access for about ten seconds once I disconnect and reconnect. I have turned off IPV6, I have turned off power saving options for the network adapter, no viruses. Any new ideas? Also, I had to disconnect and reconnect four times just to get to this edit screen- and will likely have to do the same just to post it- it's that bad.

  • HOSTS ignored when disconnected [closed]

    - by Synetech
    Problem I’m seeing a strange and extremely frustrating problem. Any system that is not connect to the Internet (Windows 7 shows the no Internet access icon because it cannot constantly ping Microsoft’s servers) cannot even access locally hosted servers. Hypothesis The problem appears to be that the HOSTS file is not being used to resolve DNS entries when there are no active NICs. Tests / Reproduction You can reproduce it as so: Disconnect a system from the Internet (make sure all wired and wireless connections are disconnected). If necessary, add an entry to the HOSTS file (e.g., 127.0.0.1 foobar or 127.0.0.1 foobar.com) Open a command-prompt Type ping foobar or ping foobar.com Observations The screenshots below show a clear and demonstrative example. In the first snap, a laptop is connected to a router wirelessly. The HOSTS file has only three entries and they resolve just fine. In the second snap, the wireless radio is turned off, so the entries in the HOSTS file are ignored. Moreover, notice that pinging localhost still works even without any active NICs (as does 127.0.0.1), but it is using the IPv6 address (must be hard-coded). You can see the same results in Windows XP with no IPv6 installed, so it has nothing to do with IPv6. I tried pining what should have resolved to 127.0.0.1 while the desktop system (with no wireless NICs) was connected via its Ethernet adapter, then again after pulling the cable from the router and waiting a couple of seconds, then again after plugging the cable back in. The same thing happens if instead of pulling out the cable, the NIC is disabled through software (the [Disable] button in the NIC’s Status dialog or via Device Manager). Conclusions It looks as though the HOSTS file is only being read and used if there is an active NIC, otherwise it is being ignored. This makes some sense in that if there are no active network adapters, then presumably there will not be any network activity, and thus no need to resolve host names via the HOSTS file. This assumption is specious however because it precludes locally hosted virtual servers. The HOSTS file should be used regardless of external DNS server connectivity, otherwise you cannot use simple/consistent/testing-production names for locally hosted servers when not connected to the Internet (for example web servers; help servers for Visual Studio, 3dsmax, etc.; and so on). Question Does anyone know how to force Windows to use the HOSTS file even if there are no active NICs? Appendix Figure 1: While the wireless NIC is connected to the router (the cable-modem is in standby, so no external Internet connectivity). Figure 2: With the wireless radio turned off (the Ethernet port is not unconnected in both cases). Figure 3: Same results in XP with no IPv6

  • Cassandra hangs with kernel exception when adding jna jar to classpath

    I have a fresh installation of cassandra v2.0.8 on a RedHat Enterprise Linux v5. I have added a sym link of the jna.jar in cassandra's /lib folder.

  • Kickstart based installation of RHEL 6.4 from USB

    - by Peter
    I want to setup some brand new servers with RHEL 6.4. Servers do not have DVD, so, I have to use USB for the installation. I already have a custom ISO with a kickstart file that I use on servers with DVD flawlessly. I used iso2usb to move the ISO t? my USB. When I boot from the USB, the ks file is found, anaconda starts, but then stops with the following error: "The installation source given by device ['sda1'] could not be found. Please check your parameters and try again" Notes: The USB IS the sda. My custom ISO file is renamed to linux.iso from iso2usb and it is present in the root directory of the USB. Kickstart file has the following entry: harddrive --partition=sda1 --dir=/ Please help me to automate the installation with kickstart.
