  • Vboxheadless without a command prompt (VirtualBox)

    - by joe
    I'm trying to run VirtualBox VM's in the background from a service. I'm having trouble starting a process the way I desire. I'd like to start the virtualbox guest in headless mode as a separate process and show nothing as far as GUI. Here's what I've tried: From command line: start vboxheadless -s "Ubuntu Server" In C#: ProcessStartInfo info = new ProcessStartInfo { UseShellExecute = false, RedirectStandardOutput = true, ErrorDialog = false, WindowStyle = ProcessWindowStyle.Hidden, CreateNoWindow = true, FileName = "C:/program files/sun/virtualbox/vboxheadless", Arguments = "-s \"Ubuntu Server\"" }; Process p = new Process(); p.StartInfo = info; p.Start(); String output = p.StandardOutput.ReadToEnd(); //BLOCKS! (output stream isnt closed) I want to be able to get the output to know if starting the server was a success. However, it seems as though the window that's spawned never closes its output stream. It's also worth mentioning that I've tried using vboxmanage startvm "Ubuntu Server" --type=vrdp. I can determine whether the server started properly using this. But it shows a new command prompt window for the newly started VirtualBox guest.

  • Windows 7 SP1 not being offered on Windows Update

    - by Ian Boyd
    i have no option to install Windows 7 Service Pack 1 (SP1) on my computer. Why is the option to install Windows 7 SP1 missing from Windows Update? i'm less interested in why the option is missing, and more interested in how to diagnose why the option to install Windows 7 SP1 is being hidden. Following the suggestions in KB2498452 - You do not have the option of downloading Windows 7 SP1 when you use Windows Update to check for updates: Confirm that Windows 7 SP1 is not already installed and that you are not running a prerelease version of Windows 7 SP1 i am not already running SP1, or a pre-release SP1: Check for pending updates Update 976902 may have to be installed on your computer before Windows 7 SP1 will be offered in Windows Update. i already have 976902 installed: Verify that an incompatible version of SafeCentral is not installed on your computer Windows SP1 may not appear in Windows Update if certain versions of SafeCentral are installed on your computer. SafeCentral is a security program that is manufactured by SafeCentral, Inc. i do not have SafeCentral installed (i've never heard of such a thing): Check whether you have Intel integrated graphics driver Igdkmd32.sys or Igdkmd64.sys and whether you upgraded the driver i do not have an Intel GMA: Make sure that you did not use vLite to customize your Windows 7 installation i did not use vLite to customize my Windows 7 installation. Again, i've never heard of such a thing. Update One: Here's proof that i've checked for updates "today" (3/2/2011): And that i'm not being presented the option of installing SP1 (i dispatched an update to Silverlight and a fix for IE9 being hosted in a Direct2D or Direct3D application; so updates themselves do work): Update Two Tried the Windows Update Troubleshooter: Window 7 Service Pack 1 is still not available. Update Three Here is the tail end of windowsupdate.log.

  • Gluster bricks are offline and errors in logs

    - by Roman Newaza
    I have substituted all the IP addresses with hostnames and renamed configs (IP to hostname) in /var/lib/glusterd by my shell script. After that I restarted Gluster Daemon and the volume. Then I checked if all the peers are connected: root@GlusterNode1a:~# gluster peer status Number of Peers: 3 Hostname: gluster-1b Uuid: 47f469e2-907a-4518-b6a4-f44878761fd2 State: Peer in Cluster (Connected) Hostname: gluster-2b Uuid: dc3a3ff7-9e30-44ac-9d15-00f9dab4d8b9 State: Peer in Cluster (Connected) Hostname: gluster-2a Uuid: 72405811-15a0-456b-86bb-1589058ff89b State: Peer in Cluster (Connected) I could see mounted volumes size change on all the nodes when I execute df command, so new data is coming. But recently I noticed error messages in app log: copy(/storage/152627/dat): failed to open stream: Structure needs cleaning readfile(/storage/1438227/dat): failed to open stream: Input/output error unlink(/storage/189457/23/dat): No such file or directory Finally, I have found out some bricks are offline: root@GlusterNode1a:~# gluster volume status Status of volume: storage Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick gluster-1a:/storage/1a 24009 Y 1326 Brick gluster-1b:/storage/1b 24009 N N/A Brick gluster-2a:/storage/2a 24009 N N/A Brick gluster-2b:/storage/2b 24009 N N/A Brick gluster-1a:/storage/3a 24011 Y 1332 Brick gluster-1b:/storage/3b 24011 N N/A Brick gluster-2a:/storage/4a 24011 N N/A Brick gluster-2b:/storage/4b 24011 N N/A NFS Server on localhost 38467 Y 24670 Self-heal Daemon on localhost N/A Y 24676 NFS Server on gluster-2b 38467 Y 4339 Self-heal Daemon on gluster-2b N/A Y 4345 NFS Server on gluster-2a 38467 Y 1392 Self-heal Daemon on gluster-2a N/A Y 1402 NFS Server on gluster-1b 38467 Y 2435 Self-heal Daemon on gluster-1b N/A Y 2441 What can I do about that?

  • VMware Workstation executes nonexisting and outdated File

    - by RED SOFT ADAIR-StefanWoe
    I execute a command line program from a VM (VMware 7.1.1) with Windows XP. The executable file is located on the host machine. If i start a command line in the VM, using a drive mounted as .host\SharedFolders i see the following: D:\projects\myProgram\WinRel>dir myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe D:\projects\myProgram\WinRel>myProgram.exe Processing BuildFeb 26 2009 This is wrong! The whole execution of the program behaves like the version that is outdated more than one year! I triple checked that there is no confusion or anything If i start the Program on the host or if i even start it from the VM using a UNC Path, it shows the last build date and executes as expected: C:\>dir \\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe C:\>\\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe Processing Build: Sep 2 2010 Can this behavior somehow be explained? There MUST be a cache for the host mounted drive. The program it executes does not exist anymore! If i remove it from the host, the VM can not execute it anymore. If i restore it, the behavior becomes the same again.

  • How do I use .htaccess conditional redirects for multiple domains?

    - by John
    I'm managing about 15 or so domains for a particular promotion. Each domain has specific redirects in place, as shown below. Rather than make 15 different .htaccess files that I would later have to manage separately, I'd like to use a single .htaccess file and use a symbolic link into each website's directory. The trouble is that, I can't figure out how to make the rules apply only for a specific domain. Every time I visit www.redirectsite2.com, it sends me to www.targetsite.com/search.html?state=PA&id=75, when it should instead be sending me to www.targetsite.com/search.html?state=NJ&id=68. How exactly do I make multiple RewriteRules apply for a given domain and only that domain? Is this even possible to do within a single .htaccess file? Options +FollowSymlinks # redirectsite1.com RewriteEngine On RewriteBase / # start processing rules for www.redirectsite1.com RewriteCond %{QUERY_STRING} ^$ RewriteCond %{HTTP_HOST} ^www\.redirectsite1\.com$ # rule for organic visit first RewriteRule ^$ http://targetsite.com/search.html?state=PA&id=75 [QSA,R,L] RewriteRule ^PGN$ http://targetsite.com/search.html?state=PA&id=26 [QSA,R,NC,L] RewriteRule ^NS$ http://targetsite.com/search.html?state=PA&id=27 [QSA,R,NC,L] RewriteRule ^INQ$ http://targetsite.com/search.html?state=PA&id=28 [QSA,R,NC,L] RewriteRule ^AA$ http://targetsite.com/search.html?state=PA&id=29 [QSA,R,NC,L] RewriteRule ^PI$ http://targetsite.com/search.html?state=PA&id=30 [QSA,R,NC,L] RewriteRule ^GV$ http://targetsite.com/search.html?state=PA&id=31 [QSA,R,NC,L] # catch-all rule, using the same id as the organic visit RewriteRule ^([a-z]+)?$ http://targetsite.com/search.html?state=PA&id=75 [QSA,R,NC,L] # end processing rules for www.redirectsite1.com # begin rules for redirectsite2.com RewriteCond %{QUERY_STRING} ^$ RewriteCond %{HTTP_HOST} ^www\.redirectsite2\.com$ # rule for organic visit first RewriteRule ^$ http://targetsite.com/search.html?state=NJ&id=68 [QSA,R,L] RewriteRule ^SL$ http://targetsite.com/search.html?state=NJ&id=6 [QSA,R,NC,L] RewriteRule ^APP$ http://targetsite.com/search.html?state=NJ&id=8 [QSA,R,NC,L] # catch-all rule, using the same id as the organic visit RewriteRule ^([a-z]+)?$ http://targetsite.com/search.html?state=NJ&id=68 [QSA,R,NC,L] Thanks for any help you may be able to provide!

  • Create App_Data and register Excel application on ASP.NET deployment? (IIS7.5)

    - by Francesco
    I am deploying an ASP.NET MVC3 application in IIS7. I already deployed other applications but they never made use of the App_Data folder or any additional component such as the Interop library. I used the one click deployement and I sue the default application pool. When I launch the application I immediately get an error stating: [web access] Sorry, an error occurred while processing your request. [browse from IIS7] Could not find a part of the path 'D:\Data\Apps\OppUpdate\App_Data\Test.xlsx'. Then I manually added the App_Data folder inside the deployment directory and the application starts regularly. Then when it comes to the taks that uses the Interop library, I get the following error: [web access] Sorry, an error occurred while processing your request. [browse from IIS7] Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). Is there any way to automatically add the App_Data folder when using 1 click deploy? How can I register the Interop services? Thanks you, Francesco

  • QuickTime Player sounds much better than iTunes

    - by Gene Goykhman
    I am playing a 320 kpbs encoded music MP3 in iTunes and the sound is substantially worse than the exact same file played back in QuickTime Player (Max OS X 10.8.5). I have maxed out system volume and iTunes playback volume. I have disabled all the audio processing features in iTunes (equalization, sound enhancer, etc.) The audio coming from iTunes still sounds resampled and/or processed, whereas QuickTime Player appears to be playing it "as is". Even when I Get Info on the MP3 file in Finder and play it back directly from the Get Info window it sounds good. It's just iTunes that seems to be mangling the song. I can notice a difference on virtually all my music, so it's not just one particular MP3. I suspect the issue is that iTunes is doing some kind of audio processing but I can't find a way to turn it off. This is the newest iTunes (11.1), but the problem has probably been going on for a while... I just switched to decent earbuds and started noticing the difference. What's the best way to force iTunes to play back the file as-is, or as close as possible to how QuickTime Player/Finder would play it?

  • Upgrade Debian to unstable on VirtualBox: udev problem

    - by Ken
    I'm running Debian stable on VirtualBox on Windows Vista 64-bit Ultimate. It's been running great, but I needed some newer packages, so I put sid in my sources.list to upgrade to unstable (as I've done a dozen times on various Linux boxes over the years). When I upgraded, something went screwy and it asked me to run apt-get -f install to fix them, which gave this: (Reading database ... 77846 files and directories currently installed.) Preparing to replace udev 0.125-7+lenny3 (using .../archives/udev_151-3_amd64.deb) ... Since release 150, udev requires that support for the CONFIG_SYSFS_DEPRECATED feature is disabled in the running kernel. Please upgrade your kernel before or while upgrading udev. AT YOUR OWN RISK, you can force the installation of this version of udev WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file. There is always a safer way to upgrade, do not try this unless you understand what you are doing! dpkg: error processing /var/cache/apt/archives/udev_151-3_amd64.deb (--unpack): subprocess new pre-installation script returned error exit status 1 insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current start runlevel(s) (2 3 4 5) of script `vboxadd-x11' overwrites defaults (empty). insserv: warning: current stop runlevel(s) (0 1 6) of script `vboxadd-x11' overwrites defaults (empty).

  • Using AddEncoding x-gzip .gz without actual files

    - by STATUS_ACCESS_DENIED
    With Apache (2.2 and later) how can I achieve the following. I want to transparently compress using GZip encoding (not plain Deflate) the output when a certain file is queried with its name plus the extension .gz, where the .gz version doesn't physically exist on disk. So let's say I have a file named /path/foo.bar and no file foo.bar.gz in the folder to which the URI /path maps, how can I get Apache to serve the contents of /path/foo.bar but with AddEncoding x-gzip ... applied to the (non-existing) file? The rewrite part appears to be easy, but the problem is how to apply the encoding to a non-existent item. The other way around also seems to be simple as long as the client supports the encoding. Is the only solution really a script that does this on the fly? I'm aware of mod_deflate and mod_gzip and it is not what I'm looking for - at least not alone. In particular I need an actual GZIP file and not just a deflated stream. Now I was thinking of using mod_ext_filter, but couldn't bridge the gap between rewriting the name of the (non-existent) file.gz to file on one side and the LocationMatch on the other. Here's what I have. RewriteRule ^(.*?\.ext)\.gz$ $1 [L] ExtFilterDefine gzip mode=output cmd="/bin/gzip" <LocationMatch "/my-files/special-path/.*?\.ext\.gz"> AddType application/octet-stream .ext.gz SetOutputFilter gzip Header set Content-Encoding gzip </LocationMatch> Note that the header for Content-Encoding isn't really needed by the clients in this case. They expect to see actual GZIP files, but I want to do this on-the-fly without caching (this is a test scenario).

  • Query Execution Failed in Reporting Services reports

    - by Chris Herring
    I have some reporting services reports that talk to Analysis Services and at times they fail with the following error: An error occurred during client rendering. An error has occurred during report processing. Query execution failed for dataset 'AccountManagerAccountManager'. The connection cannot be used while an XmlReader object is open. This occurs sometimes when I change selections in the filter. It also occurs when the machine has been under heavy load and then will consistently error until SSAS is restarted.

  • 32 core (each physical core) 2.2 GhZ or 12 core (6 physical cores) 3.0GHZ?

    - by Tejaswi Rana
    I am working on a multithreaded application (Forex trading app built on C#) and had the client upgrade from the 12 core 3.0GHZ machine (Intel) to a 32 core 2.2 Ghz machine (AMD). The PassMark benchmark results were significantly higher when using multicores doing Integer, Floating and other calculations while for a single core calculation it was a bit slower than the pack (others that were being compared to with similar config as the 12 core one). Oh it also comes with 64 GB RAM (4 times as the other one) and a much faster SSD. So after configuring and running the application on that machine, not only did it not perform as well, it was significantly slower. We're talking about 30seconds - 1 minute slower on an app that usually completes processing within 5-20 secs. The application uses MAX DEGREE of PARALLELISM (TPL) which I've tried setting to number of cores and also half of that. I've also tried running single threaded and without setting any limits in parallel threading. While it may be the hardware has some issues, I am wondering if the CPU processing speed is the issue. I can overclock to 3.0 GHZ. But is that even a good idea? Server Info - AMD http://www.passmark.com/forum/showthread.php?4013-AMD-Dual-6272-performance-is-60-lower-than-benchmarks Seems that benchmark was wrong to start with - officially. Intel i7 3930k OS (same in both) Windows 7 Professional 64-bit

  • cPanel web servers mounting home partition to a NAS or SAN

    - by Scott
    I currently have 2 cPanel web servers that are little 1RU dual cpu quad core xeons. They have a lot of resources for processing and handling web requests, and never exceed more than 10% cpu usage. They also have plenty of RAM. The problem is though that they both have RAID 1 160Gb SAS hard disk drives in them that are 75% full, and growing by the day. I didnt think that the amount of disk usage would be so high, but due to the nature of the sites hosted, this has become an issue. The easy fix would be just to upgrade the hard drives to something bigger (probably not of the SAS variety), but I am thinking of keeping the current machines as "processing servers" and buying a central "storage server" with about 12TB of storage. The /home/ partition on each of the 1RU servers would be mounted to a NAS or SAN point on this central storage server. My questions are: - Has anyone got a cPanel setup where they mount /home/ to a NAS or SAN elsewhere? If so, can you provide details as to what you did and how it went :) - Any recommendations on networking? Is gigabit ethernet enough? Is TCP/IP going to be a noticable performance problem? Anyone used a TOE key? - Anyone benchmarked or had any performance issues with SAN over NAS? Any help greatly appreciated. Scott

  • SQL Server rolling forward lots of transactions, what should I look at?

    - by Anthony D
    I am running SQL Server Express on a Windows XP Embedded box. It runs for a day or two, doing some transactional processing for a POS type system, and with another system pulling data out to an OLAP DB for processing. After a while, I see in the event viewer the sequence SQL Server puts out when it restarts, copy rights, command line parameters, and so on. It seems like that coincides with our OLAP process crashing. I then see that when it restarts our transaction DB, it does a recovery, pulling in 10K or so in transactions that need to be rolled forward. Does this mean SQL has crashed? I don't really see much to indicate what happened. Update 1 I noticed I have my memory limit set to 1MB per query and 2TB for the server. These are the defaults. I only have one GB in the box. We have seen SQL crash a whole box by just using all the system memory. In this case though the whole box is up when we get to it.

  • Nginx Slower than Apache??

    Hi, I've just setup 2x identical Rackspace Cloud instances and am doing some comparisons and benchmarks to compare Apache and Nginx. I'm testing with a 3.4k png file and initially 512MB server instances but have now moved to 1024MB server instances.

Can anyone give any advice? Thanks, Ian

  • Configure PEAR on CentOS 6 and PLESK

    - by RCNeil
    I'm hoping to get a little assistance with configuring PEAR to work properly. I have a PHP file that's calling PEAR's mail and mail-mime files, and I believe I am missing some steps because I keep getting the very common Warning: include_once(Mail.php): failed to open stream: No such file or directory Warning: include_once(Mail_Mime/mime.php): failed to open stream: No such file or directory It is installed - Installed packages, channel pear.php.net: ========================================= Package Version State Archive_Tar 1.3.7 stable Console_Getopt 1.2.3 stable Mail 1.2.0 stable Mail_Mime 1.8.3 stable PEAR 1.9.4 stable Structures_Graph 1.0.4 stable XML_RPC 1.5.4 stable XML_Util 1.2.1 stable And according to this TUT, I need to configure it appropriately in each vhost. I have already gone through and adjusted the php.ini file, but when the TUT speaks of the php_admin_value open_basedir "/var/www/vhosts/example.com/httpdocs:/tmp:/usr/share/pear:/local/PEAR" in my /var/www/vhosts/example.com/conf/httpd.include file I kind of get lost. There are several httpd.include files in that directory, all preceded with very long numerical strings. All I want to do is have an email attachment in my form.... Any insight or similar experiences shared would be greatly appreciated.

  • FreeBSD 8.1 unstable network connection

    - by frankcheong
    I have three FreeBSD 8.1 running on three different hardware and therefore consist of different network adapter as well (bce, bge and igb). I found that the network connection is kind of unstable which I have tried to scp some 10MB file and found that I cannot always get the files completed successfully. I have further checked with my network admin and he claim that the problem is being caused by the network driver which cannot support the load whereby he tried to ping using huge packet size (around 15k) and my server will drop packet consistently at a regular interval. I found that this statement may not be valid since the three server is using three different network drive and it would be quite impossible that the same problem is being caused by three different network adapter and thus different network driver. Since then I have tried to tune up the performance by playing around with the /etc/sysctl.conf figures with no luck. kern.ipc.somaxconn=1024 kern.ipc.shmall=3276800 kern.ipc.shmmax=1638400000 # Security net.inet.ip.redirect=0 net.inet.ip.sourceroute=0 net.inet.ip.accept_sourceroute=0 net.inet.icmp.maskrepl=0 net.inet.icmp.log_redirect=0 net.inet.icmp.drop_redirect=1 net.inet.tcp.drop_synfin=1 # Security net.inet.udp.blackhole=1 net.inet.tcp.blackhole=2 # Required by pf net.inet.ip.forwarding=1 #Network Performance Tuning kern.ipc.maxsockbuf=16777216 net.inet.tcp.rfc1323=1 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.recvbuf_max=16777216 # Setting specifically for 1 or even 10Gbps network net.local.stream.sendspace=262144 net.local.stream.recvspace=262144 net.inet.tcp.local_slowstart_flightsize=10 net.inet.tcp.nolocaltimewait=1 net.inet.tcp.mssdflt=1460 net.inet.tcp.sendbuf_auto=1 net.inet.tcp.sendbuf_inc=16384 net.inet.tcp.recvbuf_auto=1 net.inet.tcp.recvbuf_inc=524288 net.inet.tcp.sendspace=262144 net.inet.tcp.recvspace=262144 net.inet.udp.recvspace=262144 kern.ipc.maxsockbuf=16777216 kern.ipc.nmbclusters=32768 net.inet.tcp.delayed_ack=1 net.inet.tcp.delacktime=100 net.inet.tcp.slowstart_flightsize=179 net.inet.tcp.inflight.enable=1 net.inet.tcp.inflight.min=6144 # Reduce the cache size of slow start connection net.inet.tcp.hostcache.expire=1 Our network admin also claim that they see quite a lot of network up and down from their cisco switch log while I cannot find any up down message inside the dmesg.

  • How can I do a large file upload using Sinatra, haml, nginx, and passenger?

    - by mmr
    Hi all, I need to be able to allow a user to upload 30-60 mb files at a time. Right now, I'm solving the problem with a simple form post: %form{:action=>"/Upload",:method=>"post",:enctype=>"multipart/form-data"} - @theModelHash.each do |key,value| %br %input{:type=>"checkbox", :name=>"#{key}", :value=>1, :checked=>value} =key %br %input{:type=>"file",:name=>"file"} %input{:type=>"submit",:value=>"Upload"} This form allows the user to select processing options contained in theModelHash and upload a file for processing. Problem is, this method both freezes the user's UI and also requires that the entire form be reposted when the user presses the 'back' button. I've looked at SWFUpload, but have no idea how to integrate that into my relatively simple app. There's a page here about integrating it with Rails, but I'm using Sinatra, and am new enough to this whole web programming thing that I don't know how to modify those files to work with what I need to do. Is there a how-to to add large file uploads to my form there? Something relatively simple that just adds in a progress bar and doesn't repost? I feel like I'm having to triple the size of my application just to make this feature play nice, and that's bothering me a bit.

  • ffmpeg: converting an avi to a reduced, shareable flv/mp4...

    - by meder
    I recently followed a guide and recompiled my ffmpeg so x264 is enabled. I used some generic settings to convert my 700 MB avi file to a mp4 file, the result was a 407MB mp4 file. The original avi file's settings: Codec: DX50 Resolution: 704x304 Frame rate: 23.976023 Stream 1 Codec: mpga Type: Audio Channels: 2 Sample rate: 48000 Hz Bitrate 179 kb/s Command I used: ffmpeg -i input.avi -acodec libfaac -ab 128k -ac 2 -vcodec libx264 -vpre hq -crf 22 -threads 0 output.mp4 The settings of the output file (output.mp4): Codec: avc1 Resolution: 704x304 Display resolution: 704x304 Frame rate: 11.988011 Stream 1 Codec: mp4a Type: Audio Channels: 2 Sample Rate: 48000 Hz Bits per sample: 16 Bitrate: 1536 kb/s The quality of the output mp4 is pretty nice, it seems as if it's pretty much the same as the original source. However, I'm trying to reduce the filesize and I'm not really sure whether I should go with an flv format or keep it mp4. The advantage the flv would have obviously is that it would be playable with a flash player ( I have come across some swf players which take a flash parameter to play an flv file ).. but maybe I could use the video element, as I'm only going to be displaying this video privately so I don't have to worry about supporting legacy browsers such as IE. Can someone recommend some settings to specify in order for the filesize to be around ~100-150MB or so? I don't mind a reduction in quality, nor do I mind resizing it - I was going to do it initially but I wasn't sure what the guidelines were ( if any ) for dealing with resolution.. since this video's is 704x304 would it still be ok if I forced it into one that isn't perfectly fit for the aspect ratio? I have no clue about that part. I realize that I could have probably specified 28 instead of 22 for the CRF, I'm not sure if I should do that as opposed to maybe specifying smaller resolution, which might make it smaller as well?
