• Good quality voice communication software over Internet for windows

  - by ORA600

  I regularly attend over-the-phone meetings, where is a polycom/polispan device on the other side. The quality of the sound is bad, even those whose English is a first language sometimes are struggling to realize what is being said on the other side. I understand this is because of too aggressive audio compression in the line. Does anyone know any good audio chat software which does not over-compress audio stream. The IP channel between two offices is wide enough. In other words, you should be able to listen to a music (not only a speech) from the remote side with good quality. So, Skype is too over-compressing as well. Does anyone know anything like that?

• Format External HD on Airport Extreme Base Station?

  - by David.Chu.ca

  I just got an Airport Extreme Base Station. I am planning to use this one replace my current Linksys router. This works fine. My another purpose of getting this device is to use its USB port to connect to several external HDs as my backup Time Machine. I can see one 500GB HD through Airport Base Station. However, I cannot format it by using Disk Utility. What I did is to connect the HD to my iMac directly first and then clean and format the disk by Disk Utility application. Then I move the HD to the Airport Base Station. After that I can designate the HD as my Time Machine destination. Is there any way to format the HD connected to Airport Base Station? Any issues to use an external HD through Airport Base Station for Time Machine backups?

• Root partition full? CentOS

  - by Joao Heleno

  Hi! I'm running CentOS 5.4 and my / is full. I wanted to install gparted but in order to do that I must install Priorities and it's when I get an error saying / is full so I can't go forward.

• 2nd/3rd version of wireless network appears

  - by neildeadman

  I replaced an old SpeedTouch ADSL router with a Netgear DG384 that I have and whilst doing so decided to change the wireless password. For this question assume my wireless network SSID is DeddersHome. On my netbook and macbook pro (running Win7) it won't connect to the Internet. When I hover over the tray icon for wireless it says "DeddersHome 2" and "DeddersHome 3" have no internet connection. What are these additional wireless networks? I can't see them in the wireless network list on any wireless device I have. Wired connections and wireless through my iPhone work fine. I saw this before with the SpeedTouch, but it just went away!! I also have one Apple AirPort Express connected to the wireless network which my Xbox is connected to (wired). This all worked before... I am going to remove AirPort to see if it is this causing the problem, but thought I'd ask the question to give it time for an answer whilst I continue to search. Cheers

• HP DL380 G5 Predictive Drive Failure on a new drive

  - by CharlieJ

  Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

• SCCM deploy from VMware XP image

  - by HannesFostie

  We recently set up the latest version of SCCM and I managed to capture a .wim image from a virtual machine (build and capture task sequence). I want to use this .wim file to deploy winXP to different hardware, and therefor need to add device drivers to the task sequence. I created a driver package per laptop type, and deployed for the first time. However, I am getting a BSOD (0x00007B) which leads me to believe theres a problem with the storage drivers. After adjusting the task sequence to try and point to the mass storage drivers (which are applied at F6, I suppose) I do not get a list of compatible drivers (the list is empty). I looked around, and found some issues regarding hdc class drivers that are not recognized as mass storage drivers. The workaround suggested changing the INF file to make the driver a SCSIAdapter class driver, and importing these again, but to no avail. The list remains empty. Any help is much appreciated

• Juniper J4350 out of order

  - by Benjamin Baron

  I have got two (2) Juniper routers J4350 that are out of order : All the interfaces are down (leds on the interfaces don't ligthen, ping dosen't respond) No output on the console port (even when booting) I've tried to reset the router (holding the RESET CONFIG button on the front panel during 15 seconds) and nothing happened, even while booting the device I've opened the router to check the fans. I've removed some dust and nothing has changed. I wanted to precise that the leds on the front panel are all on: The POWER led is green The STATUS led is red The ALARM led is on and is orange The HA (High Availablity) is on and orange as well I have found nothing on the Internet to solve this problem... Thank you for helping me :)

• backup software that ignores user rights

  - by Chris

  Hi, As a computer technician I have to reinstall systems allmost daily (when it can't be repaired ;-)) My problem is that I recover user files by hand and a external mounting device. Most of the time it works fine, but also weekly I have systems with passwords and personal files which are often not sucessfull recovered. I know you can change owner, but when people have 30 GB's af data, my backup computer works for ages to change the rights. Can anyone think of software (commercial is no problem) which does the following: * backup user data without having user rights troubles * have a option to choose what to backup (email accounts, documents, etc, etc) even when it's externaly mounted, in short, it reconizes the folder structure) * Works on different OS's like XP, Vista, W7

• Does Windows 7 support multiple simultaneous nVidia graphics cards with different drivers?

  - by mckenzieg1

  On one of my dev machines at work (currently running XP), I have two nVidia graphics cards: Quadro NVS 440 (my original card, for my three primary monitors) GeForce GTX 275 (just added, for CUDA development) I can get both cards to work OK by installing the latest GeForce drivers, but I get some annoying-but-not-crippling display artifacts on the Quadro's screens (mostly scattered black rectanges where repainting fails for a few bits of UI in certain applications). Under XP, this seems to be the best I can do. I can use Device Manager to supposedly install different nVidia drivers for the two cards (the latest Quadro drivers for the NVS, the latest GeForce drivers for the GTX), but I actually end up with the same driver for both, because the driver dlls all have the same names and get installed on top of one another in the system directory. I have read that Win7 has a new video driver architecture that better supports multiple heterogeneous cards. Does anyone know if that will handle my scenario? If so, it will give me a compelling reason to get that machine on Win7 ASAP.

• Dye Sub printer with specific prints remaining - can I command-line query this?

  - by Jason N

  Hey, I've got a Sony Dye-Sub printer that holds ink/paper sets - i.e. a very certain amount of ink and paper for ~200 prints. This information is available to me from within Control Panel Printers Preferences Printer Device Information (i.e. current 189 remaining prints). Any way I can perhaps get this information from the command line? I'd like to write a little program to tell me when the number of prints gets low (i.e. < 20), rather than suffer the annoying Windows "run out of paper" popup. I've found the Windows VBScript print utilities, but can't seem to find the request I need for this. Any suggestions? Jason

• Symmetrix gatekeepers on Solaris 10

  - by Milner

  I have some Solaris machines that are connected to EMC Symmetrix for SAN storage. Apparently the Symm has a gatekeeper device that is used with the symmetrix CLI. We don't need the CLI, but I have these gatekeeper devices that constantly fill /var/adm/messages and the like with corrupt label errors. Is there anything I can do (short of deleting the devices on machine start) to get rid of them? Or should I just try to get our SAN guy to get the installer for the CLI? These things are getting annoying, and the devfsadmd daemon keeps rediscovering them on boot.

• Easy way to restrict permissions in an elementary school computer lab?

  - by Andrew

  I'm putting together an elementary school computer lab. I have nine winxp pro machines that are not networked and do not have internet access (no money to do either). I've created separate student and admin accounts, and have the students set as limited users. However, I'm interested in further restricting their permissions. I want to make it such that they cannot: -delete any files, even just from their own profile -rename any files -move around the icons on the desktop -change any display settings -access a usb device without a password (they bring in their own from home which are chock-full of viruses) Oh, one last thing, they still have to be able to save word documents. Is this even possible? I can download software, but, like I said: no internet, no server.

• Identify SATA hard drive

  - by Rob Nicholson

  Very similar question to: Physically Identify the failed hard drive But for Windows 2003 this time. Scenario: Four identical SATA hard drives plugged into motherboard (no RAID controller here) Configured as single drive in Windows as a spanned volume One of them is starting to fail with error "The driver detected a controller error on \Device\Harddisk3" How do you cross-reference Harddisk3 to the physical SATA connection on the motherboard so you know which drive to replace? I know replacing this drive will trash the spanned array requiring it to be rebuilt anyway so my rough and ready solution is: Delete the spanned partition Create individual partitions on each drive labelled E: F: G: and H: and work out which one is Harddisk3 Power down, remove each disk one at a time, power-up until the drive letter disappears But this seems a rather crude method of identifying the drive. The SATA connectors will be numbered on the motherboard but I appreciate this might not cross-match to what Windows calls them. Thanks, Rob.

• tradeoffs of iSCSI vs. AFP when using Time Machine with a NAS?

  - by ajit.george

  I'm setting up a home NAS device (Synology DS409) that I'm planning to use for Time Machine backups (amongst other things). What are the tradeoffs between using iSCSI or AFP to mount the backup volume? The Synology wiki suggests that iSCSI is better if the Mac will be frequently disconnected from the network or sleeping, from the point of view of the volume automatically remounting. What about filesystem consistency? Given that unplugging a USB drive without properly unmounting it often requires the Time Machine volume to be repaired, would iSCSI have the same issues? Thanks in advance.

• Can't find second partition on encrypted drive with two partitions

  - by Thomas Uhrig

  I have a drive with two partitions, a system partition (Windows 7) and a partition just for data. Both are encrypted with the same password. I didn't had any problems, but yesterday my laptop gets broken. Now, I'm trying to connect the drive via USB to a new laptop and read it. The problem is, that I only see the system partition, not the one with my data. When I click on "Select Device", I can see my drive as "Harddisk 1" with 300 gb. But I only see a single partition "Partition1" with 117 gb. I'm unable to find the second one. It's not a hidden partition. Any ideas? Thanks.

• Use Mac Pro as time machine, server and editing station?

  - by Dan

  Background: My fiancée needs a Mac Pro for movie editing and rendering. I need a web server and a backup solution for my MacBook Pro. Idea We thought we could split the costs of the Mac Pro and set it up to act as both a web server and a backup device. Question Is this a good idea? Specifically: Is it easy to set it up to incrementally backup one or several laptops over wifi? And what software would you recommend? Is it silent and stable enough to run a web server continuously? Will it manage all this, including simultaneous editing? Thanks.

• How to find out if the screen is WLED or RGBLED on Dell Studio XPS 16?

  - by Abhijeet

  I just ordered the Dell Studio XPS 16 with i7 and 16" RGBLED screen. This upgrade from WLED LCD to RGBLED LCD charged me more $$. But now when I view the order online, it lists this part as "320-8335 Premium FHD WLED Display, Obsidian Black, 2.0 MP Webcam". When called Dell, the rep says this part is RGBLED screen and the "premium" is for RGBLED. I want to make sure they are shipping me the RGBLED screen and not the WLED. Is there any way to verify this after I receive (either from Device Manager or BIOS or somewhere in system settings)? Also, is there any published specifications / criteria that we can run (some third party software) on this monitor which can tell if this is WLED or RGBLED?

• Any way to know what files were in a broken ZFS pool?

  - by Erik Tjernlund

  I have a large ZFS pool of 4 combined drives. Now, the filesystem can not be mounted: pool: tank state: UNAVAIL status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the missing device and online it using 'zpool online'. see: http://www.sun.com/msg/ZFS-8000-3C scan: none requested config: NAME STATE READ WRITE CKSUM tank UNAVAIL 0 0 0 insufficient replicas c10t0d0 ONLINE 0 0 0 c8t0d0 UNAVAIL 0 0 0 cannot open c8t1d0 ONLINE 0 0 0 c10t1d0 ONLINE 0 0 0 Probably a broken drive (c8t0d0). I'm not overly concerned by the loss of the data, but I'd love to know exactly which files were in that pool. Is there any way to get a listing of what files were there?

• Windows Vista - Can't start any program without choosing "Run as administrator"

  - by Dave Forgac

  A friend called me saying that her computer recently said it was applying a Windows update when it was shutting down. Now when logged in as her normal user whenever she tries to run any program from the start menu or from a shortcut on the desktop she gets the following popup: "Windows cannot access the specified device path or file You may not have the appropriate permissions to access the item" If she right-clicks and chooses 'Run as administrator' the program will run. We checked the Windows update history and it said the update was applied successfully and that there are no updates available. Unfortunately I'm in a different city so I don't have physical access to the system to look at it any further. Has anyone had a similar problem or have any suggestions?

• One PC, 4 iOS Devices, 4 iCloud Accounts?

  - by Eric J.

  I have one PC running iTunes, my iPhone, and one iPod for each of three kids. Ideally I would like the iPhone to use my iCloud account and each iPod to use an iCloud account specific to each kid. According to Apple: You can ... use one Apple ID for iCloud services and another Apple ID for store purchases However, the method described Enter the Apple ID you want to use for iCloud in Control Panel Network and Internet iCloud. Enter the Apple ID you want to use for Store purchases (including iTunes in the Cloud and iTunes Match) in iTunes iTunes Store. would require that all iOS devices share the same iCloud account if they use iTunes on the same PC. Short of having one PC per family member, is there a method to use different iCloud accounts on each iOS device?

• routing traffic between two network cards through firewall

  - by RubyFreak

  I'm trying to test a network device (firewall) using a Linux box, with two network cards, one interface connected to the WAN zone and another interface to LAN zone. The configuration is similar with that |ETH0| <-> | FW | <-> ETH1 So from both interfaces I'm able to ping the respective firewall interface. But i'm not able to fire something like: ping -I eth0 ip.from.eth1 and to get any answer. Is that possible or should the linux network namespace solution or user level tcp stacks (VMs are out of question)

• Resizing mysterious partition written by DDing an ISO file

  - by Jon

  I downloaded clonezilla and then wrote it to a USB flash drive with this: dd if=clonezilla.iso of=/dev/sdb I've confirmed that the system boots and clonezilla runs from the flash drive. I want to store a clonezilla backup on the same flash drive clonezilla is running on, but I tried it and ran out of space, so I started looking at how to resize the mysterious partition type that was generated from the ISO. fdisk -l /dev/sdb .... Device Boot Start End Blocks Id System /dev/sdb1 * 1 111 113664 17 Hidden HPFS/NTFS .... I've tried using ntfsresize from the Debian ntfsprogs package. I'm trying gparted next, but thought I'd ask here if anyone knows a neat way to resize a partition created on flash from a liveCD image. Thanks in advance Jon ps. Assume Debian 6 please.

• VirtualBox, physical disks, and snapshots

  - by noamtm

  I have an Ubuntu guest installed on a raw HDD (entire disk, not a partition). It runs just fine under WinXP. In addition, I was able to boot directly into it (using the BIOS boot-device selector). At some point, I have created a snapshot of the VM. I have made some changes since then. Today, after a long time, I tried booting into the "VM" disk. It worked, but all the data there is pre-snapshot (or, rather, frozen at the snapshot). Can I somehow merge the changes since I took the snapshot into the physical state?
