• MySQL com_select?

  - by symcbean

  I'm looking to tune my query cache a bit. According to 7.6.3.4. Query Cache Status and Maintenance in the manual: The Com_select value is given by this formula: Qcache_inserts + Qcache_not_cached + queries with errors found during the column-privileges check However in 5.1.5. Server Status Variables it suggests that this is maintained by the DBMS. Having said that mysql> show status like 'Com_select%'; Always returns a value of 1 - and I'm pretty sure I've run more than one non-cached select query on my database since it started. It looks as if other people are similarly confused. Is this status variable redundant? Which bit of the manual is wrong? TIA

• How do I stop GNU Freetalk from automatically filling in the buddy name?

  - by Journeyman Geek

  I'm using GNU Freetalk along with expect in order to send notifications to my phone – Freetalk has a readline interface, and I use expect to make a series of non interactive scripts that send information to another Jabber account. I'd like to have these scripts end freetalk 'properly' – that is to say user@domainname message one user@domainname message two /quit which would print out message one message two then quit. However Freetalk 'helpfully' adds user@domainame automatically so I get message one message two /quit as the output. The expect script still ends, but there's a delay. How would I stop Freetalk from adding in the 'buddy' address automatically?

• HP laptop won't recognize wireless adapter

  - by Dennis Williamson

  I have an HP Pavilion dv6400 series laptop with an NVidea chipset which is the subject of a class action lawsuit. The symptom (PDF) that I'm experiencing is that the system fails to recognize that there is a wireless adapter installed. It doesn't appear in Device Manager. Is there some way, short of installing a new adapter, that I can work around this problem? The system is running Windows Vista Home and has the latest BIOS (F42) and Windows updates and drivers. See this related question where I ask how to use an old Windows Mobile phone as a Wi-Fi (not cellular data) tether.

• How to install Active Directory Users and Computers for Windows 2008

  - by Mark Arnott

  I want to install the administration tools on a Windows Server 2008 (R1) machine. On Windows 2003 you installed adminpak.msi, but I can't find such a file for 2008. Is this a "feature" in Server Manager? If so what is it named? ---UPDATE--- So I drilled into the server Features list and I have "Remote Server Administration Tools" but it only includes File Services, Print Services and Web Server. This is a member server in a domain but not a domain controller. It is Windows 2008 (original) not R2. Still, why can't it run AD users and computers from this machine?

• Can I use the voice & SMS features of my GSM SIM through my laptop?

  - by i..

  My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!

• GVFS Locations Not Available In ~/.gvfs

  - by Aaron Copley

  So, I can mount GVFS locations correctly (specifically CIFS) either from the Gnome "Places" menu, or via the command line gvfs-mount, but the filesystem is not mounted in the expected location; ~/.gvfs. In fact, running the mount command does not list any GVFS filesystem at all. This is reproducible for non-root users while the root user behaves as expected. Strace reveals a permissions error for the user mounting the filesystem for the path /home/username/.gvfs. Ownership and permissions are correct and there are no extended attributes for the path as revealed by lsattr. Also, /root/.gvfs and /home/username/.gvfs are on the same filesystem. All packages are current. Any ideas?

• Why is idle windows VM using so much CPU?

  - by Jeff Shattock

  I have 2 VMs running as guests on a KVM virtualization platform running on Ubuntu 10.04. One VM is an Ubuntu 10.04 system, the other is a Windows 7 system. When both machines are completely logged out, the Linux machine uses 1% CPU, the Windows one 45-50%, according to top. The graphs in virt-manager seem to back this up. Theres nothing installed on the Win7 image that would be running in the background; its as fresh as can be. Why is the Windows VM using so much more than the Linux VM, when both are logged out and idling?

• Generating and collaborating on network map diagrams?

  - by Ian C.

  I have to turn out some network topology maps for very large networks. I'd like the format for the maps to be something other people can also edit and contribute to regardless of what software I'm using on my Mac to build them. I don't mind spending money on my end for software, but I can't require that my clients spend any money. I also can't promise my clients are also using OS X -- they could be running Linux or Windows. Is there a best software application on OS X for producing maps that I can share with other, non-OS X, users? Is there a best format for sharing topology maps that I should use when exporting the maps to disk?

• How do I stop ssh-agent from forgetting my password after I login to the screen session from SSH?

  - by Shwouchk

  I have a screen session open in an lxterminal window. If I SSH somewhere, the first time it happens, an ssh-agent window opens and asks me for my private key passphrase, and after that ssh goes right on. If I log in from outside to this machine and attach to the screen session however, ssh-agent now asks me every time I connect for my passphrase, in the terminal. Is there a way to avoid this and to let it continue using the X agent, or at least to have the non-X agent remember the passphrase?

• Sound card issues (High Definition Audio Controller)

  - by Prakash R

  I have a 5-year-old Acer Aspire 4520. Until a month back it was working beautifully on Windows 7 32bit. But then out of the blue, the sound stopped working. I've tried reinstalling the OS 3-4 times. The sound came back a couple of times, but it stopped working after a reboot. Even after installing the sound drivers, I don't see any entry in the Playback tab of the Sound applet in Control Panel. I see a High Definition Audio Controller entry in Device Manager. I disabled and uninstalled it, but Windows reinstalls it automatically. I'll share specific hardware details if anybody here needs to know. The processor is "AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55". Any help would be appreciated.

• Making an SSD drive the primary boot/system drive

  - by David Ebbo

  [Not much of a hardware guy, so please excuse my ignorance :)] I just ordered an HP Pavilion Elite HPE-450t (desktop), which came with Win7 installed on the hard drive, using two partitions (C: and D:). Separately, I bought a 128GB SSD that I intend to use as my system drive. I got it in there and connected it, and right now, it's the J: drive (which was the first letter available in disk manager). My goal is for the SSD to get a clean OS install be the C: drive, and to clean out the other hard drive and make it D: (for misc data storage) Question #1: the motherboard has two SATA plugs. Does it matter which one I use for which drive? Question #2: what's the right way to install Win7 on the SSD in a way that it ends up being the C: drive? Do I need to switch some things around in the current Win7 that came with it, are can I do all that while installing Win7 on the SSD?

• task scheduler - run interactively as any user with admin credentials

  - by Force Flow

  I'm trying to deploy a scheduled task with a GPO. The task is set to run at login and executes a batch file, which then executes an EXE file. However, I also need it to be interactive and run with admin privledges to bypass the UAC prompt for a username and password when the exe file runs. I created the task for "Vista and later". I've tried running the task as mydoman\administrator and as NT AUTHORITY\Authenticated users with "run only when user is logged in" and "run with highest privledges" selected. If I log in as anyone but administrator, the task does run in the background, as I can see the cmd.exe process running in task manager as mydomain\administrator. Only if I log in as administrator do I then see the cmd window with the batch script running. How can I get the cmd window to display no matter which user logs in?

• win2008 R2 server core software RAID

  - by shimonyk

  I am trying to set up software raid on a win2008 R2 server core. I have the disks configured as dynamic. In the server manager gui, i can see the disks, but when i right click, the option to set up "new mirrored volume" is not listed. I tried it with the command line using diskpart, and it gives the error "Virtual Disk Service Error: The size of the extent is less than the minimum." The drive are a new pair of 1Tb disks. Is this not supported in server core, or am i missing something else? Thank you

• Virtualbox VM (spawned by Vagrant) running but inaccessible. What now?

  - by Matt V.

  I have a Virtualbox VM running Ubuntu that was started by Vagrant. At some point my ssh session connected to the guest stopped responding. I tried "vagrant halt" from a terminal window on the host (OS X). The shutdown process seemed to also hang. Shutting down the Oracle VM VirtualBox Manager doesn't shut down the VMs themselves. Is there a way in either Vagrant or VirtualBox to force the running VM to shutdown? When running desktop guest OSes, closing the GUI window presents several options for shutting down the guest, but I don't know how to do the equivalent when the guest is running headless.

• Managing PHP processes on Windows 7 (with WAMP)

  - by Andrea

  Is there a way to manage (especially list and kill) long-running PHP processes on a Windows 7 system set up with WAMP? Every once in a while, I'll accidentally throw an infinite loop into a PHP process and want to kill it. Right now, all I can think to do is to restart all my WAMP services but sometimes the PHP processes manage to survive right through the restart, i.e., I still see them outputting to logs even after WAMP's restarted. And if the process isn't logging, then I have no way at all to know when/if it's been killed. Not to mention, this will wipe out everything I'm doing with WAMP, not just a single process. I don't seem to see anything relevant in the Windows Task Manager, but maybe I'm missing something.

• Opening a Corrupted winmail.dat file

  - by tearman

  I have a set of winmail.dat files that apparently have evolved from a set of emails with corrupted headers. It looks like Exchange 2010 changed the headers around sometime last September and basically rendered exported .eml files unable to open. Now the HTML/PlainText emails seem to do ok, but the files that use RichText (specifically Microsoft's TNEF format) will not open in any program, Microsoft or not. I've attempted to use many different non-Microsoft converters and they see it as a corrupted message as well. If I remove the headers of the email, rename it as a winmail.dat file, some emails will open in Word, but most won't. If you take a look at the email in a text editor, there are null characters EVERYWHERE that distort the email itself. Anybody have any experience with this and/or suggestions on how to at least open it?

• Issue about Exchange 07 SP2 Backup in SBS 08

  - by Bastien974

  Hi, I'm trying to backup my Exchange 07 SP2 with the Windows Server Backup. Since it's supposed to make a exchange-aware backup with the SP2, I created a scheduled full backup of the C: (where is located my First Storage Group). The backup is successful, but when I go in Mailbox database's properties, I see that the last full backup is 2 months ago (a that time backup worked but we had some issue then). In Server Manager, Features, I checked that I have Windows Server Backup Features checked. What am I missing ? Thank you !

• Time tracking similar to Paymo Plus on Debian

  - by aditya menon

  PaymoPlus is free (closed source but no fees) PaymoPlus sits in my System Tray all day, and records every window/tab I open I would like to know if a similar app exists for Debian. Paymo for Windows/Mac has the additional sweet feature of being able to drag and drop working windows/tabs and the time spent into the tasks, but one can live without this. I would at least need to know which tasks got how much time in a 'sum total' calculation so I can enter that time into my Paymo reporting. Any ideas? Paymo does have a desktop widget for Linux but it is a dumb (non-sentient) manual time entry tool, not like Paymo Plus automatically recording everything being done.

• How can I determine what is causing SQL Server 2008 Express to hang Windows 7?

  - by thelaughingdm

  I have SQL Server Express 2008 installed on a Windows 7 (32-bit) developer workstation. Whenever I run an application that accesses SQL Server the Windows 7 shell hangs when the application closes. Applications like Windows Explorer and Task Manager become completely unresponsive. The task bar will not allow any interaction. The only way to recover the system is to power cycle. Two of the applications in use when this happens are NUnit and SQL Server Management Studio. NUnit always runs the unit tests that interact with the database fine. SQL Server Management Studio will sometimes cause the problem while trying to explore the database. The Windows event log does not show any events that are obviously connected to the problem. I have reverted and reinstalled SQL Server Express 2008 several times. What can be done to identify what is causing SQL Server Express 2008 to hang the Windows 7 shell?

• Best practice for ONLY allowing MySQL access to a server?

  - by Calvin Froedge

  Here's the use case: I have a SaaS system that was built (dev environment) on a single box. I've moved everything to a cloud environment running Ubuntu 10.10. One server runs the application, the other runs the database. The basic idea is that the server that runs the database should only be accessible by the application and the administrator's machine, who both have correct RSA keys. My question: Would it be better practice to use a firewall to block access to ALL ports except MySQL, or skip firewall / iptables and just disable all other services / ports completely? Furthermore, should I run MySQL on a non-standard port? This database will hold quite sensitive information and I want to make sure I'm doing everything possible to properly safeguard it. Thanks in advance. I've been reading here for a while but this is the first question that I've asked. I'll try to answer some as well = )

• Looking at desktop virtualization, but some users need 3D support. Is HP Remote Graphics a viable solution?

  - by Ryan Thompson

  My company is looking at desktop virtualization, and are planning to move all of the desktop compute resources into the server room or data center, and provide users with thin clients for access. In most cases, a simple VNC or Remote Desktop solution is adequate, but some users are running visualizations that require 3D capability--something that VNC and Remote Desktop cannot support. Rather than making an exception and providing desktop machines for these users, complicating out rollout and future operations, we are considering adding servers with GPUs, and using HP's Remote Graphics to provide access from the thin client. The demo version appears to work acceptably, but there is a bit of a learning curve, it's not clear how well it would work for multiple simultaneous sessions, and it's not clear if it would be a good solution to apply to non-3D sessions. If possible, as with the hardware, we want to deploy a single software solution instead of a mishmash. If anyone has had experience managing a large installation of HP Remote Graphics, I would appreciate any feedback you can provide.

• SATA controller installed but not working? (No drives show up/Don't see card's BIOS)

  - by johnnycakes

  Hi, I have an old Promise FastTrak S150 TX4 SATA controller card. I put it in an old machine running Windows Server 2003. I booted the machine. The new hardware was detected. I installed the drivers. So now in Device Manager under "SCSI and RAID Controllers" I see "Win Server 2003 Promise FastTrak S150 TX4 Controller" and "Win Server 2003 Promise RAID Console SCSI Processor Device" I previously had the card in a machine that is now dead. When I booted that machine, during the boot process I would see the card info displayed and the drives that were attached. Boot would finish and my drives would be available. When I boot this new machine I never see that screen/text. No hard drives are available/visible. What am I missing? Thanks.

• How to load previous kernel via ssh?

  - by Aamir

  I work remotely on my work computer. I am also the root of the workstation that I am sharing with my colleague. Yesterday, I upgraded the kernel to 2.6.31-17 when asked by the update manager but refrained from restarting because I knew my NVIDIA and several other kernel modules wouldn't work. Unfortunately my colleague who is a linux noob restarted the machine and here I am :( I am thinking of changing the symlinks /initrd.img and /vmlinuz to the previous kernel image and use kexec. Please tell some better way to load the 2.6.31-16 release of kernel from ssh and not the grub boot menu. I am using Ubuntu Karmic.

• Gnome - windows always open top left

  - by BobTodd

  I find this a highly annoying "feature" on a wide screen monitor that my mostly used apps - terminal and gedit always open directly under the top-left corner of my screen and I have to drag them to my eye position each and every-time. I have tried installing the CompizConfig Settings Manager and using the feature to position windows centre, but this has had no effect - the force feature here isn't working for me either. I can use e.g. gnome-terminal --geometry=140x50+50+50 for the terminal but this doesn't work for gedit. Any ideas? Thanks
