• Best technique for reusing a Windows system image across configurations

  - by Martin Wiboe

  We are a small company that provides solutions for ventilation systems. Part of the solution is a "controller" which communicates with the ventilation equipment. These controllers are simply Dell computers that come with our Windows 7 system image on them and sometimes some special hardware. We typically do a batch of 10 controllers at a time. We have been using Norton Ghost to apply the system image, but this process breaks because Dell changes the system configuration often, and our Windows image now does not contain the correct drivers. This is especially a problem when they change the RAID controller. To improve this, I see 2 options: use some kind of virtualization and install a hypervisor on each PC. This would solve the driver problem, but probably cause trouble with our special hardware. use some method of adding the proper drivers to our Windows image in offline mode. I haven't got much experience in either of these approaches. How would you solve our problem?

• Sudden loss of Wi-Fi connectivity on OS X

  - by GJ.

  Occasionally while I work, without any special provocation, I lose connectivity via Wi-Fi. Other devices connected to the same wifi network have no interruption, and the problem gets resolved once I reboot my MacBook Air, so it's definitely a local problem. Observations: The Wi-Fi symbol in the menu indicates that I'm still connected, but apps can't actually connect neither to the Internet nor to other devices in the LAN. I can't connect to an alternate Wi-Fi network (e.g. Wi-Fi tethering via iPhone). I can connect to the Internet via iPhone USB tethering but this seems to only work some of the time. Only a reboot solves the problem but a regular restart gets stuck on a grey screen with rotating wheel (after all applications have closed) and I have to do a hard reset. How should I go about troubleshooting this? It used to happen very rarely but now is becoming more frequent (approaching once every 2-3 days on average).

• Configure Raid On Red Hat 5

  - by Sopolin

  Hi all, I have a problem with configure raid on red hat enterprise linux. The problem is when I create raid on two hard disks. It works successfully but after I remove one hard disk. It works normally. It means that I plug in one hard disk for testing configure raid. But after that I put both hard disks and create other file. The raid is cleared. My question is: Why do I turn off server machine, it clears raid that I configure first time before I turn off? Could anyone help to solve this problem? Thank, Ung Sopolin

• Qmail & Open Relay on local domains

  - by Jonathan

  Hello. I have a dedicated server on 1&1 and I manage it with Plesk. The problem is that if I try to send a mail outside the server, I must to authenticate with the email and the password, but if I send an email to a address inside of my server I don't need neither email or password. This is a problem because the spammers are sending mails without any problem to the server accounts. We are receiving about 900 - 1200 emails everyday! What can I do? I use qmail on CentOS Thanks

• Why are my USB 2.0 devices crashing Windows XP?

  - by BenAlabaster

  Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

• How should I troubleshoot a problematic wireless connection on Linux?

  - by Gearoid Murphy

  I recently purchased a netgear 150 usb wireless dongle for use with my 11.10 Xubuntu amd64 system. Using the network-manager interface, I can see local wireless networks and enter the authentication details for my local wireless lan. Unfortunately, the connection does not seem to work, I keep getting notifications that my wireless has disconnected (but none indicating that I've connected). When I examine syslog, it seems to indicate that I've successfully associated with the wireless switch and that dhcp has successfully acquired an ip address but the log shows that the dhcp process keeps sending requests, eventually dropping the connection. 'ifconfig wlan0' never shows the dhcp address logged in syslog. I suspect that the problem lies with the usb dongle, my configuration or the wireless switch but I am not certain how to isolate the problem, can anyone provide some insight on how I should go about homing in on the cause of this problem or verifying the functionality of the individual components, thanks.

• Why is Windows Explorer not responding?

  - by William Barnes

  I am having the seemingy popular problem with Widows Explorer not responding. I have tried the AUTRUNS and turned off everything recommended. I have run SCANNOW 3 times and it comes back clean. When booting in safe mode it appears to work. I read someplace that the problem could be a service program, but can't remember where I read it or how to do it. Something about turning off all service programs and then turning them back on one at a time. The problem is I don't remember what it said to do. Any and all help is greatly appreciated. as an FYI here is my system stats Sorry I can't access that part of control panel right now because windows explore not responding. I have an HPdesk top with a AMD quad core processor 1.8GB 1.5TB sata drives (a 1TB and a 500GB) Nvidia 8400 graphics card a 2mb internet connetion wireless 2 DBD R?W drives.

• Localized database for customers

  - by Jim

  The company I work for, has just moved to AWS - and currently they have one very large central database with the instance currently located in America. However, one of their clients has requested that all of their data is held in the EU. So creating an AWS instance in Ireland isn't a problem, the problem is the database and how to manage it. We were considering having another database that runs in the EU for European customers, and use a different primary key step, so that the primary keys will never conflict in case the two locations need to be merged in the future. The problem is, if we have a customer that uses our system in both America, and the EU we would have to create 2 accounts for that user, and reporting across both regions would not be possible as the connection time would be too high. Is there an alternative to set this up?

• Single domain user can't install a specific shared network printer

  - by drpcken

  I have a file server serving up shared network printers. Never had any issues in the past. I have a specific domain user (just 1) that gets this error when trying to install a specific printer: You do not have sufficient access to your computer to connect to the selected printer This user can install all the other printers no problem. All my other domain users can install the printer with no problem. I've removed the driver from the local client and tried again but with the same problem. Even as an administrator I get this error. Is there something I'm missing?

• Green bar on top of every (web) video, distorted colors too

  - by Walter Maier-Murdnelch

  Hey since a few days I have a problem with some videos I watch on the web (youtube, vimeo etc). There is a green bar on the top of the video and the colors are distorted, it looks like they are somehow shifted. I am not sure since when this problem appeared, I guess it might have been an update for the flash player. Anyways, I found a workaround. Disabling the hardware acceleration helps. right click on video - settings - disable hardware acceleration. After reloading of the page the green bar is gone. The problem is taht this setting doesn't seem to be persistent and so I have to disable it again on every other video. How can I make this setting permanent or how to get rid of the green bar alltogether? (I will add a screenshot later)

• ESX - Initialization for vmfs2 failed with -1

  - by ov4

  I recently purchases a bunch of R710's from Dell. I installed VMWare ESX on them. The installation process finishes without a problem; however once ESX boots the following error displays at the botton with red letters: 00:00:02:21.493 cpu11:4119) mod:2971: Initialization for vmfs2 failed with -1 I installed on two different servers and the same error appears. The curious thing is that if I install ESXi 3.5 or 4 there is not problem. What does this problem mean, and how can I resolve it?

• How to make a server check it's own availability on the web?

  - by Javawag

  Hi all, Just a quick question – my server is running at my house serving www pages at www.javawag.com. The problem is that my home internet connection keeps dropping randomly - for about 10 mins at a time. This is only an intermittent problem and will go away soon I hope. However, my server doesn't recover properly - when the connection comes back, I can still access it at 192.168.0.8 (locally) without any issue, but at www.javawag.com there's no reply! (Just an aside - my home internet connection is dynamic ISP, the domain www.javawag.com points to javawag.dyndns.org which in turn points to my IP, updated every minute by ddclient on the server) Is there some way for the server to check if it's accessible from the outside world periodically, and if not restart Apache/reboot? Oh, and if I reboot the problem fixes itself also! Javawag

• Logitech bluetooth audio receiver quality

  - by lietus

  I bought a Logitech Bluetooth Audio receiver, and have run into a problem: When playing audio, it contains short hisses/clicks on higher tones or vocal+heavy instrumental music (Sound quality appears to be unclean). I'm not sure what could be the reason, but this only happens when I play from certain devices. My laptops (a Dell XPS Win7, and an Asus Eee seashell Win7) and my phone (Samsung Player 5) both have the problem. However, when I tried using a Samsung S2 phone, the audio was crystal clear. Seems that this could be something with Bluetooth transiting device.. Has anyone encountered a similar problem?

• scp to remote servers stalls, unable to isolate cause

  - by Rolf

  When I copy a large file (100+mb) to a remote server using scp it slows down from 2.7 mb/s to 100 kb/s and downward and then stalls. The problem is that I can't seem to isolate the problem. I've tried 2 different remote servers, using 2 local machines (1 osx, 1 windows/cygwin), using 2 different networks/isps and 2 different scp clients. All combinations give the problem except when I copy between the two remote servers (scp). Using wireshark I could not detect any traffic volume that would congest the network (although about 7 packets/sec with NBNS requests from the osx machine). What in the world could be going on? Given the combinations I've used there doesn't seem to be any overlap in the thing that could be causing the trouble.

• Reply to mailman archived message

  - by Jasper

  (not exactly sure if this is the right place for this question, but I trust you will migrate it if it isn't) I was having a problem with gdb, and while there issue appears to be recurring, I found only one instance of someone recently experiencing the same problem. I found this other instance on a mailman archived mailing list. Then I tried some more things and finally solved the issue with gdb. So, now I want to report back the solution I found to the mailing list. However, this is really only of use if mailman recognizes my mail as being the same thread as the original problem, but I do not have that mail (just the online archived version of it) so I cannot reply to it. My question: How can I make sure mailman considers my mail as a reply to that thread? Is simply copying the topic enough?

• Windows 7- New Windows Are Not Displayed

  - by Peter

  I am running an up-to-date and OEM version of Windows 7. I have been experiencing an annoying problem for the past few weeks where new windows are not displayed 70-80% of the time. For example, when I launch notepad, the notepad window is not displayed or when I select save from the file menu, the save dialog is not displayed. The window is there, but it is not being displayed; the screen is not refreshed. The way to work around this problem is to force a system-wide refresh by pressing CTRL+SHIFT+DEL and then cancelling hiding all windows using "show desktop" then displaying the window needed via taskbar Can anyone please point me in the right direction to solving this problem? What could be causing this?

• tool for advanced ID3 tags handling and audio files ordering

  - by Juhele

  I have following problem – some of my files do not have complete ID3 tags and some have typos or small differences in writing - so finally, my portable player sees “Mr. President” as different artist from “Mr President” and so on. I would need some tool which could search similar tags and then allow me to correct the typos or for example override “artist” in all selected files by manually entered text. The same with empty tag items – sometimes, the track name, album etc. is OK, but artist is missing etc. Without touching the audio quality, of course (but this should be no problem, I think). I already tried tools in Winamp, Songbird and other players and currently most advanced free tool I tried is Tagscanner. However, it is not able to to solve the problem with similar tags. Do you know such tool? Preferably free and for Windows, if possible. However, if you know some commercial app able to do this, please let me know.

• Blocked port 25 on Windows 7 64 bit

  - by Michal Gow

  Strange problem. I have 2 computers connected to Wifi router. One with Windows Vista & second with 2 operating systems: SUSe Linux and Windows 7 64bit on it. Computer with Vista can connect to SMTP server of my email provider (and any other) using port 25, and can connect to a mail server using telnet mail.server.com 25 if this port is open. Computer with dual operating system can (using Linux) do the same. The same computer, with the same hardware (Wifi card etc.), and using the same WiFi router, cannot however use Port 25 and cannot Telnet into any smtp server. So the problem is in Windows 7. I did uninstall all antivirus software and disabled the firewall. The problem is still here. Is there way how find out which software is blocking this port?
