• Audio doesn't work on Windows XP guest (WS 7.0)

  - by Mads

  Hi, I can't get audio to work with on a Windows XP guest running on VMware Workstation 7.0 and Ubuntu 9.10 host. Windows fails to produce any audio output and the Windows device manager says the Multimedia Audio Controller is not working properly. Audio is working fine in the host OS. When I open Multimedia Audio Controller properties it says: Device status: The drivers for this device are not installed (Code 28) If I try to reinstall the driver I get the following error message: "Cannot Install this Hardware There was a problem installing this hardware: Multimedia Audio Controller An Error occurred during the installation of the device Driver is not intended for this platform" Has anyone else experienced this problem?

• using svnadmin in a php script

  - by fabjoa

  Howdie Scenario: Allow developers to submit new application packages to a market server. Developers run a bash script which contains a cURL call to market server (localhost/market/submit/$app-name). The submit script on the server creates a new folder in existing svn server with the name of the submitted app. Script on dev side waits for HTTP to issue a success message and then do a svn checkout in dev local machine. Problem: The submit script on the market server failed to create new svn directory through code: echo `svnadmin mkdir -m 'added new package $package' http://localhost/market/packages/$package`; this does not echo nothing and when I go on http://localhost/market/packages, the folder has not been added and the revision number has not been incremented. I've tried from a terminal in market server chown root:www-data /usr/bin/svnadmin but still no luck. Somebody has come acrosss similar problem? Any solutions? Thanks!

• Homework with allocate subnet IP address

  - by Don Lun

  I'm having difficulty solving a subnet allocation homework problem. Assume that a university has an address block 128.205.224.0/19. It has to allocate addresses for 2 departments' networks, each of size 1800, and for 4 offices, of sizes 550, 600, 650, and 750 nodes respectively. Assuming that the university network allocates addresses sequentially from the beginning of the allocated allocated address space, what are the prefix allocations for these subnetworks? I first thought in this way: There should be 6 subnets in the network. So I need 3 bits for the subnets. So 3 + 19 = 22 bits should be the network bits. Then there are only 10 bits left. 2^10 = 1024 < 1800, so this cannot work. Could you guys give me a hint or some thoughts for solving this problem?

• Slow wifi from Windows Server 2003 virtualized in XenServer

  - by John Clayton

  I'm a brand spanking new user of OS X, coming from a lifetime of Windows use. I've been setting up my new Macbook Pro and have run into a very unusual problem. Over wifi, I am unable to copy files to or from my Windows Home Server. The problem seems to exist only over wifi, and only to WHS. Here are the details of my setup: 2010 Macbook Pro (Core i7), OS X 10.6.3 Windows Home Server PP3 (virtualized in XenServer 5.5) Windows 7 Ultimate x64 desktop Windows 7 Ultimate x64 in Boot Camp D-Link DIR-655 wireless N router Here is what I've done to narrow down the problem: Files copy fine from WHS to OS X when using gigabit ethernet Files copy fine from desktop to OS X when using gigabit ethernet Files fail to copy from WHS to OS X when using wifi (error -51) Files copy fine from desktop to OS X when using wifi Files copy fine from WHS to Boot Camp when using wifi Files copy fine from desktop to Boot Camp when using wifi From what I can tell, it seems to be some sort of issue between OS X and WHS, but I can't for the life of me see what would be different between shares on WHS and my desktop. They are both connected using smb://ADDRESS (I've tried both by IP and name). I can browse the shares on the WHS, but copying to OS X fails. I originally found the issue while installing VS2010 off an ISO from WHS, mounted to a Windows 7 VM using VMware Fusion. During the installation the VM was unusable - even the clock got behind the host be about 8 minutes. Once I plugged in the ethernet and disabled the wifi things picked up and finished quickly. The Fusion 3.1 RC is the only I think of that I installed that may have messed with the wifi driver. I've also tried resetting the wifi router, and have changed it from being G & N to N-only. Under Boot Camp I get similar speeds as my wife's N laptop. Any ideas? Thanks! Update: The issue has been further narrowed down to Windows Server 2003, which Windows Home Server is based on, running in XenServer with the XenServer tools installed.

• Providing high availability and failover using MySQL on EC2

  - by crb

  I would like to have a highly-available MySQL system, with automatic failover, running on Amazon EC2 instances. The standard approach to solving this is problem Heartbeat + DRBD, but I've found a lot of posts suggesting DRBD doesn't work on EC2, though none saying exactly why. Obviously, a serial heartbeat or distinct network is out of the question in the virtualised environment. It would also be good to have the different servers be in different availability zones, but we're getting into a much harder problem there. What are peoples' opinion on having a high uptime solution in "the cloud"?

• iptables: matching multiple ip addresses

  - by Tax

  Hi guys, I am working on a iptables rule to apply after my shorewall script has initialized my firewall. I want a spicific IP (10.0.1.19) address in my lan to be redirected to 10.0.64.1 except if it is going to paypal. I have the following rule, and that works like a charm iptables -t nat -A PREROUTING ! -d 1.2.3.4 -s 10.0.1.19 -j DNAT --to 10.0.64.1 My problem is that paypal uses multiple ip addresses, and I am not allowed to have multiple IP-addresses. https://ppmts.custhelp.com/cgi-bin/ppdts.cfg/php/enduser/std%5Fadp.php?p%5Ffaqid=92 On top of this problem I would like to know how to remove the rule again, without having to restart shorewall. Kind regards Tax

• Installing SQL Server 2005 Express on Windows 8 [closed]

  - by Angel

  We have an application that installs a custom instance of Microsoft SQL Server 2005 Express as part if the whole installation process. Microsoft states that SQL Server 2005 Express is not compatible with Windows 8, but in reality it seems to install and work perfectly fine. The only problem is that during the installation a dialog appears saying it's not compatible, and offers options to get help online, continue with the installation anyway, or cancel. If you chose to continue anyway on all these incompatibility prompts, then the SQL server instance is installed without any problem whatsoever. Does anyone know if there is a way to suppress these incompatibility messages during the SQL service installation (or any installation, for that matter)?

• Burning Xvid and Dvix Files problems

  - by chobo2

  Hi I am using windows 7 ultimate 64 bit edition and Nero 8. Recently I noticed that every time I go to nero and burn a dvix/xvid file as a data DVD and try to play it in a dvd player that supports these types it does not load up and play. I then go to my XP machine with Nero 6 on it and burn the exact same file as a data DVD and it works in the exact same dvd player. I am not sure why this is happening? I am not sure if it is windows 7, nero 8 or my actual dvd burner that is the problem. How should I go about and figure out what the problem is? Thanks

• Windows will not go into standby

  - by Robert

  When I select Start-Turn off computer-Standby the 'turn off computer' option window closes, and then nothing else happens. I can start new applications, and Windows acts like I never selected standby. If I have a TV program scheduled to record I get a window asking if I'm sure, there are programs scheduled to record - and the computer just keeps running after I select yes. (If a program is not scheduled then that task in not running/in memory - this problem happens even if I'm not watching TV and no TV scheduling task is running.) This problem happens regardless of whether Media Center is running. Windows XP SP3 Media Center Edition, all current updates installed.

• Problems setting up home web server

  - by putmatrix

  Has anyone been able to get a server working with the router smcwbr14t-g? Although I have been able to get Apache set up correctly and my website works on the internal IP 192.168.2.101, I've been running into a dead end when trying to get it to show up on my external IP. In my router, there is no option for port forwarding, but there are options for a 'virtual server'. Following the manual, I have it set up like this: http://imgur.com/zrcV7.png I also disabled the firewall. I configured Apache to listen to ports 80, 81, and 443, none of which solved the problem. However, the IP's 192.168.2.101:443 and :81 load fine. The problem is that I still cannot load the web site from my external IP, either from my computer or outside.

• HP dv6000 laptop powers on only if plugged in

  - by Ben

  My HP dv6000 laptop will not run on battery power. It will only run while plugged into the wall. I have already replaced the battery, but it still will not operate on battery power. The problem began slowly. The original battery's life got shorter and shorter, until eventually it would only last ~45 seconds before going into hibernation. Finally, the battery would not work at all, so I threw it out and just used it without a battery. I bought a replacement recently.... but the problem persists. When I connect the new battery to the system, the "charging" light turns on for about 30 seconds, then goes dark. I'm assuming there's something wrong with the internal charging circuitry? If this is the case, how would I go about fixing this, short of buying a new motherboard? If anyone could give me some assistance in confirming/rejecting my diagnosis I'd be very appreciative! :)

• how to compile VTK on Mac Air

  - by Ilan Tal

  I am trying to compile VTK on a Mac after successfully doing so on Linux. I am using CMake 2.8.9 and for a long time I had a problem where it couldn't find jni.h. If anyone else has the problem, the answer is to have JAVA_INCLUDE_PATH2 point to "-framework JavaVM". After that it successfully finds JNI and does a "Configure" followed by "Generate". According to the instructions I have the next step should be easy: in a terminal run "make -j 2". I get a message "-bash: make: command not found". Strange.... I am in the vtkBuild directory, which seems the most reasonable place. I even tried the parent directory where I have the VTK source but that didn't work either. I ran a make under Linux and had no troubles, so what do I need to do with the Mac? Thanks, Ilan

• IIS in VirtualBox serving files from shared Ubuntu folder

  - by queen3

  Here's the problem: I want to use Ubuntu. But I need to develop ASP.NET (MVC) sites. So I setup VirtualBox with Win2003 and IIS6. But I would prefer my working files to be located in my Ubuntu home folder. So I setup shared folder in VirtualBox and make IIS6 virtual directory work from there. The problem is, IIS6 can't do this. Whatever I try (mapped drive, network uri path) I get different IIS errors: can't access folder (for mapped drive), can't monitor file system changes (\vboxsvr share path), and so on. Is there a way for IIS6 in virtual machine to configure virtual application folder to be on host machine (Ubuntu) - be it shared folder, mapped drive, smb share, or whatever?

• vim default save is no file type? default setting advisable?

  - by Brady Trainor

  I just came across a problem that I seemed to have found a solution, but was a little surprised by the issue. In gVim, when I save a new document (new from "within" gVim), ala :w afile I realized it saves with I guess no file format, and thus is not visible in iPhone's PlainText app. Solution seems to be, save using :w afile.txt then the problem seems solved. Is this a good way to solve it? Should I change a default somewhere, either in Windows or _gvimrc file? I may consider doing some TeX'ing in vim at some point, so perhaps a default that allows for overriding in saving, and doesn't force txt when opening "any of all" documents.

• Remote desktop session ends abruptly with a "protocol error"

  - by Jon

  Intermittently we get a problem where a remote desktop session will get disconnected with the error message “Because of a protocol error, this session will be disconnected. Please try connecting to the remote computer again.” We are getting this with one server only which is running Windows Server 2008, connecting with Windows 7 clients. The session itself stays running, you just get disconnected, and you can try and reconnect. Sometimes you get in for a while then it will kick you out. We are connecting from Windows 7 clients. We have tried connecting using Cord on a Mac and this works fine, so it's not like the session itself is corrupted. One problem is that there are some critical applications running under the session (I know, let's not discuss the idiocy of that), so we cannot reset the session in any way during the working day – so any diagnostics must have minimum impact. Thanks, Jon

• Problems using PC as a media server with PS3

  - by Tiger

  I recently got a PS3 and decided to take advantage of the fact that it can be used to stream movies by making my PC a media server. I've done this in the past with the same router I have now before I sold my old PS3, but not on this PC. I've tried using both Tversity and PS3 Media server, but I don't think the problem lies within the configuration of either of those programs because I am unable to ping the PS3. This problem only occurs when I am using a wired connection on my pc, attempting to connect to a WLAN connection on the PS3. If I switch to WLAN on my PC I can successfully ping the PS3 and connect to the media server. Thanks

• Applescript cannot find sed during application install

  - by jsmorris

  I am attempting to install an application, but the installer fails with the following error message: sh: sed: command not found and there is an Edit and OK button in the dialog, so I click the Edit button which launches the AppleScript Editor to show me the script that is executing. Running it from within the Editor doesn't work either. The first line of the script with sed is set currdir_modified to do shell script ("echo " & currdir & " | sed 's/ /\\ /g'") I went to the terminal to make sure sed was available, and it is, in /usr/bin. This sounds like a path problem, but I am not sure where to go from here. What can I do to further troubleshoot or solution this issue? I have successfully installed this app on another mac running the same OS X version, so it is specific to my mac and the application's support is not providing any more help because it is my mac's problem, not theirs.

  - by Albert Widjaja

  Hi All, Does anyone experience this problem of corrupted .WAR file after it has been copied over the network share ? this is .WAR file (Web Archive) the J2EE application file (.WAR file is compressed with the same zip algorithm i think ?) Scenario 1: Windows Server 2008 x64 transfer into Windows XP using RDP client (Local Devices and Resources) Scenario 2: Windows XP 32 bit transfer into Windows Server 2003 x64 using shared network drive (port 445 SMB ?) for both of the scenario it always failed / corrupted (the source code seems to be duplicated at the end of line when you open up in the Eclipse / Java IDE). but when in both scenario i compressed the file into .ZIP file everything is OK. can anyone explains why this problem happens ?

• how to connect virtual box os and local machine

  - by Nrew

  This question is in connection to this question asked by a user before: http://superuser.com/questions/73470/virtualbox-vdi-file-to-vmware On how to convert vdi to vmdk or vmx using vmware converter. How do I connect the windows xp that is in virtual box to the local computer (windows 7) in a network. Because I got this error while I tried following this instruction: Give the IP address, username and password of the remote machine that you would like to convert and then hit next I got this error in vmware converter: Unable to connect the specified host 10.0.2.15 which is the ip address of the xp machine inside virtual box. It also said that there is a network configuration problem. And when I inputted the ip address from whatismyip.com which should be the same as the ip address on local machine. I didn't get the previous error but I got another one, it said that: insufficient permissions to connect to "ip address" What solution can you suggest for this problem?

• Flash player, HD videos and games are choppy

  - by Aimad Majdou

  I have a problem with flash player. HD videos from Youtube or Vimeo and flash games do not play smoothly. I'm using Flash player 11, Windows 7 Sp1, and my graphic card is Intel GMA 4500. Device Manager shows me that all drivers are installed on my computer, so i don't have any problems with drivers. When I run Google chrome, Resource Monitor shows me 15% ~ 40 % of CPU Usage and 40% used Physical Memory, but when I watch a video on Youtube or play a Flash game, the Resource Monitor shows 70% - 90% CPU Usage. Also, when I run some HD Video (Frame width : 1920, Frame height : 1080) on my computer, Device Manager shows me 80% ~ 100% of CPU Usage. before I Reinstall Windows 7, HD Videos and flash games were play smoothly I hadn't any problem with them !! I hope all these informations are enough to answer my question.

• How can I keep my keyboard clean?

  - by Billy ONeal

  I know there are lots of articles out there on getting a keyboard clean, but I'd like to prevent my keyboard from getting nasty in the first place. The biggest problem isn't anything like food particles or liquids -- my keyboards almost instantly get a coating of finger oils and dead skin cells around the edges of the keys where my fingers rest, and the result is quite nasty. I have to clean my keyboards constantly to keep the problem in check. I'm wondering if there are any good ways to reduce this kind of buildup on my keyboard.

• Refresh devices - reconnect CF card drive by script (unplug-plug equivalent)

  - by Chris

  Hello I plug a completely clean CF-card into my USB card-writer. Then I dd a mbr block of 512 bytes size to the device, which contains the partition table and the definition of one partition. Problem: While "fdisk -l /dev/sdx" correctly displays the partition, it happens that there is no device like "/dev/sdx1" after these operations (as it was not present before). Unplugging and plugging the card-writer solves the problem and makes the device(s) appear. Since I use this procedure in a script, manually unplugging and re-plugging is no option whatsoever. Is there a way to "refresh" the devices or to "unplug and re-plug" the drive by script such that /dev/sdx1 appears? Thanks for any help, Chris

• Add dpkg .symbols or.shlibs to package made using checkinstall

  - by Hubert Kario

  I have created a simple package using checkinstall of the Oracle Instantclient client libraries, the package installs without problem and is seen in the system. Problem is, that checkinstall doesn't create /var/lib/dpkg/info/oracle-instantclient11.2-basic.symbols or /var/lib/dpkg/info/oracle-instantclient11.2-basic.shlibs files so when I try to create another package (with proper build scripts) that depends on oracle-instantclient11.2-basic the build fails with dpkg-shlibdeps: error: no dependency information found for \ /usr/lib/libclntsh.so.11.1 (used by \ debian/libopendbx1-oracle/usr/lib/opendbx/liboraclebackend.so.1.2.0). dh_shlibdeps: dpkg-shlibdeps \ -Tdebian/libopendbx1-oracle.substvars \ debian/libopendbx1-oracle/usr/lib/opendbx/liboraclebackend.so.1.2.0 \ returned exit code 2 make: *** [binary-arch] Error 9 Is there an easy way to automatically create a package with .symbols or .shlibs files?
