• Windows 7 64-bit Google Chrome Makes Desktop Unresponsive

  - by Meengla

  For the past 1-2 weeks my desktop becomes unresponsive sometimes. The problem seems to happen as I load a page in Google Chrome; it could be any page though today it happened when I tried to load a page with Flash content in it. The problem is not consistent and there is no pattern. I can do a virus scan using some software (not antivirus installed--never needed that) but I strongly suspect it is some software I installed or some Windows Update. This is a very powerful Dell Optiplex 990 with 16GB RAM, so Memory shouldn't be an issue. When the problem happens the cursor becomes spinning even over the taskbar and control alt delete takes a long time. Eventually I get a message that 'this program is not responding' with end/close and 'cancel' icon. But repeated end or cancel does nothing. Then the menu for ctrl alt del comes up. The rest of the applications keep running fine though I can't get to them because the cursor is the wait-cursor. What is happening? How can I find what exactly caused the problem? Thanks.

• Converting Audio To Video Output and Attaching Text?

  - by ZeeMan

  I am currently working on a project and before i get started i thought it'd be nice to check with stackOverflow community, and see maybe they can help me with this. The Idea: I have about a thousand MP3 files that i need to convert into Video files to be upload on Youtube for my work. Here is where it gets tricky i need to also attach the Text associated with the Audio to the Video as an Image. I was thinking .ppt. The Problem: I can do this one audio file at a time but it would take me a zillion years. lol!! The Question: Can I Create Some Kind Of Program Using Let's Say XML or JavaScript Or XHTML or some other programming language to do a MASS content creation and all i have to do is feed it the Information?? possibly a script?? or is it possible to create an example .ppt file and then hack it so that i can have it reproduce itself with different information?? The Note: Thanks U In Advance For Helping Out!!! Regards, ZeeMan!!!

• Messed up partitions... system will not boot!

  - by someguy

  I did a really dumb thing. cfdisk threw an error at me saying "FATAL ERROR: Bad primary partition 3: Partition ends in the final partial cylinder", so I installed Partition Table Doctor to see if I could fix the problem. When the program started up, it told me there were problems with my partitions, and asked if I wanted them fixed (cannot remember real message, but I believe it had something to do with the cylinder boundaries), so, blindly, without thinking of the consequences, I did. Now, my system will not boot. I tried booting from the Windows 7 installation CD. I went to install a fresh copy, but it said that "No drives were found". I then opened up diskpart. According to diskpart, there is only one partition, containing one volume, assigned the letter "C". Before, I had four partitions! It is also saying that the file system is RAW. Is there any way I can fix this? I have important data that I do not want to lose. Later on... I tried fdisk with the option -l, which lists the partition table(s), and this is what I got: Ignoring extra extended partition 4 Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 64 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x163df116 Device Boot Start End Blocks Id System /dev/sda1 6 18 102400 7 HPFS/NTFS Partition 1 does not end on cylinder boundary. /dev/sda2 18 7851 62918572+ 7 HPFS/NTFS /dev/sda3 13073 30402 139196416 f W95 Ext'd (LBA) /dev/sda3 13073 30402 139196416 f W95 Ext'd (LBA) /dev/sda3 13073 30403 139203193 7 HPFS/NTFS I don't know if this will help, but it's extra information, at least.

• Win 7 crashes, PC reboots and says "Hard drive 0 not found" until I turn if off and on again

  - by Danny T.

  I recently made the move from Windows XP to Windows 7. Since then, when my computer is on for a few hours it always ends up rebooting without warning. Then the BIOS won't recognize my hard drive (hard drive 0 not found). If I turn off my computer and then on again, it boots normally. Some details: Dell Dimension 9150 Windows 7 I updated the BIOS I updated all system drivers with the latest version from Dell (SATA, Chipset, etc.) Other drivers updated too (Graphic card, sound, etc.) There is one thing that I tried after some Googling: I turned off the DMA access to the drives, but it's still rebooting after a few hours. Any clue? UPDATE 2010/12/13 Here are the events from the Event Log for today, from when I turned the computer on until it crashed: 19:17 - Error - ID 10016 - DistributedCom 20:06 - Error - ID 1008 - Customer Improvement Program (could not send data to Microsoft) 21:48 - Critical - ID 41 - Kernel-Power (System was restarted without proper shutdown) 21:48 - Error - ID 6008 - EventLog (Previous system down was not planned) 21:48 - Error - ID 1101 - EventLog (Audit Event ignored) 21:49 - Error - ID 10016 - DistributedCom Both DistributedCom events have a description along these lines (translated from French): The authorisation parameters specific to the application are not allowing Local Execeution for the COM server application with the CLSID {C97FCC79-E628-407D-AE68-A06AD6D8B4D1} and the APPID {344ED43D-D086-4961-86A6-1106F4ACAD9B} to the SID AUTHORITY NT\User System (S-1-5-18) from the address LocalHost (LRPC usage).

• Terminal emulation has stopped working. Garbage escape chars

  - by oligofren

  To enable me to do some remote administration of our servers I started using a terminal emulation program called TouchTerm Pro on my iPhone. While not the smoothest experience, it has allowed me to leave my computer behind when going out of town, which makes the slightly painful experience worthwhile. As of late, the app unfortunately no longer works. Pressing up and down keys after logging on via ssh gives me garbage like ^[[A and ^[[B. Combinations with Ctrl - like you can see in the video - no longer works either. Writing full command lines and executing by the enter key works though. Being able to search my bash history was the difference between a usable app and endless frustration, so getting it to work is essential. The app has (of course) met its end of life, not getting updated anymore. I am not quite sure, which side (client or server) that has to be "fixed"/hacked to make the control sequences work again. But is there something I can do to make it work as intended? You can see a video of TouchTerm in operation here.

• Why is my hg workbench & Adobe Reader toolbar icon a blank white page?

  - by Zasurus

  On my work's PC (windows 7 32bit) all Adobe Reader and hg Workbench icons on the toolbar (and general shortcuts for hg workbench) are just white pages (with the top left corner folded over). If you right click on the toolbar icon then right click on "TortoiseHg Workbench"(for hg workbench) then "Properties" then the "Change Icon..." button is greyed out (same for "Adobe Reader X"). Also the "Target:" is "TortoiseHg 2.4.0 (x86)" and is greyed out also the "Open File Location" is greyed out. This is the same for both Hg Workbench and Adobe Reader and seems to be the only thing that connects them. I have tried reinstalling to no avail. I also have local admin rights on the PC. I finally I have tried the following following questions without any luck (they aren't quite relevant to my issue but close): Adobe Reader program icon and pdf icons don't appear in Windows 7 Adobe PDF icon disappeared? Encase my description isn't enough to understand the issue here is a screenshot. As you can see the Hg Workbench icon (far left) and a pdf open in Adobe Reader X (second icon to from the left) are both blank and the shortcut is mainly greyed out.

• keyboard intermittently stops working, even after reinstalling windows 7; possibly a Chrome issue?

  - by neverskipbreakfast

  My keyboard intermittently stops working. Sometimes a couple of keys will work, but usually none. Sometimes if I mash a couple of the ctrl+alt+windows type keys randomly for a bit, the keyboard will let me type one more letter before stopping again. Sometimes the keys will open a program menu, but usually not. I have even completely wiped my machine and reinstalled windows 7; the problem continues. Specs: Intel iMac (early 2006, 2.0GHz, 2MB RAM, 240GB HD) running ONLY Windows 7 Professional, 32-bit (NOT through boot camp) and using a USB keyboard (Saitek Eclipse II.) *Unplugging & reconnecting keyboard does NOT fix it. *Connecting a different keyboard does NOT fix it. That one won't work, either. *Drivers are up-to-date. Removing and reinstalling drivers does NOT fix it. *Restarting the computer does NOT fix it. In fact, when the Windows logon screen appears, they keyboard won't work, and neither will the icon to pull up the on-screen keyboard. Otherwise my mouse can click around just fine. I can only log onto a non-password protected account. *Generally, logging into as different Windows user fixes it. I can then log back on to my main user account and continue work for a few hours until it happens again. *Clearing my Chrome browsing data stopped the problem from recurring for a week or so. *I use Avira free antivirus software, and repeated scans turn up nothing fishy. *I have already REINSTALLED Windows 7 (not just a restore.) The problem returned after 2 days of use. The only thing I suspect is something in Google Chrome -- I used my google account to reload all my previous Chrome extensions, saved data, etc. (Chrome Extensions Installed: AdBlock, Better Google Tasks, DropBox, FB Photo Zoom, Google Mail Checker, StayFocusd.) Any ideas? Any at all?

• TEMP environment variable occasionally set incorrectly

  - by Roger Lipscombe

  Occasionally, I find my TEMP and TMP environment variables set to C:\Windows\TEMP. They should be set to %USERPROFILE%\AppData\Local\Temp, and are configured correctly in System Properties. This manifests itself as error messages like the following: ---> System.InvalidOperationException: Unable to generate a temporary class (result=1). error CS2001: Source file 'C:\Windows\TEMP\gb_pz65v.0.cs' could not be found error CS2008: No inputs specified ...which occurs in various .NET applications (in particular Visual Studio 2010 or SQL Server Management Studio). Alternatively, SQL Server Management Studio will report: Value cannot be null. Parameter name: viewInfo (Microsoft.SqlServer.Management.SqlStudio.Explorer) If I run PowerShell elevated, then $env:TEMP is set correctly. If I run PowerShell non-elevated, then it's not. I believe that it should be set correctly in both cases. If not, it's the wrong way round. The same is true for CMD.EXE. Rebooting fixes it, temporarily, until something breaks it again. Presumably something loaded into Explorer.exe is messing with its environment variables, but what? The values in the registry are correct, even while this is happening: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment has TEMP = %SYSTEMROOT%\Temp HKCU\Environment has TEMP = %USERPROFILE%\AppData\Local\Temp By setting a breakpoint on shell32!RegenerateUserEnvironment, I'm able to trap it when it happens, but I still don't know why explorer.exe is reading the wrong environment variables. I can reproduce it consistently by broadcasting a WM_SETTINGCHANGE message (I wrote a one-line C++ program to do this). Watching the activity in Process Monitor shows that explorer.exe doesn't even look at HKCU\Environment. What is going on?

• Juniper NetScreen NS-5GT traffic monitoring

  - by blah

  I've done casual research into the subject and am truly dismayed at the lack of compatible tools for such a simple task. Maybe someone can provide assistance. We have a NetScreen NS-5GT in the office. I need to be able to get a glance of current traffic per endpoint -- I think the equivalent of 'get sessions' with byte counts/rates. I don't care about bars, graphs, and reports. Something as simple as a classic software firewall display would be perfect. I can't shell out money on something real like SolarWinds products, so a free solution is essential. I'm willing to do a little work but refuse to program something from scratch. It's not prudent right now for me to install a hub or otherwise mess around physically. There must be something out there I can use, maybe in combination. I don't believe I'm asking too much. Specific answers only please, e.g. monitoring software you know will actually work with this antiquated device. I've read about general approaches to the broader problem dozens of times already.

• Windows 7 - All Icons Missing, Explorer Progress Bar Never Finishes, Libraries Gone

  - by Alex

  since yesterday i've had three issues which all arose at the same time. windows 7 x64, i7 2.8ghz 12gb ddr3 1 - my libraries, favorites, drives are missing...basically the entire sidebar is gone. http://i.imgur.com/m8pRQ.png. yet when i open a dialog, my libraries and drives are back to normal ONLY for the dialog. i tried Restore Default Libraries. it works one time, but when i open libraries again i go back to the empty mess. restarting the computer temporarily fixes the problem. 2 - in the explorer window that's showing libraries, when i navigate to a certain folder i get an unending progress bar (the kind that turns the address bar green). yesterday when the problem started, i was saving a file to this folder. the program writing the file crashed during the write and i believe that's what caused the problem. i have sugarsync backing up that folder and when i restarted the computer sugarsync informed me that its database was corrupted, so i had to uninstall and reinstall the software. 3 - icons are missing. the Rebuild Icon Cache did not fix this. http://i.imgur.com/r9pgo.png restarting the computer temporarily fixes these problems, but when i open the directory with the initial write problem, everything stops working. edit: i should note that i did a chkdsk /f and it repaired problems. i also did the thing that verifies then restores windows files (can't remember the command now), which reported that everything was normal.

• Preserve embedded album art when converting from .flac to .ogg

  - by Profpatsch

  I want to convert my archived .flac library to .ogg for daily use. Using find ./ -iname '*.flac' -print0 | xargs -0 -n1 oggenc -q6 on the root music folder and then deleting every .flac (having copies of them in archive) seems straight forward, after trying it with one file it worked and all of the tags were transfered, too, except for one: Embedded album art! I always prefer emedded covers over folder images, since I have some albums with varying covers. One possible solution is discussed here, but the script only works if the image is already extracted: Embed album art in OGG through command line in linux One possible solution I thought about was extracting album art from every song (not every song has one, though, and some even 2 or 3!), temporarily saving it and then using the script to include it into the finished .ogg. But then I want to increase the number of processes xargs runs simultaniously to save time, so the temp images need to have a distinct name. Is there a (linux) program that knows how to handle this? Or is there a finished script floating around somewhere? It would be nice if oggenc supported adding embedded coverart and it really is a shame, since these two formats should (in theory) share the same tag format. Edit: 15 days and noone even tries to answer. It’s funny, most of my questions don’t get answered. Too hard? Wrong SE site?

• Wake on Lan Remote not waking PC while the PC does receive the packet.

  - by Nycrea

  Over the last couple of weeks, I have been trying to set up WOL from a remote location. When I use my laptop to wake the machine locally, it works just fine. (for some reason, when I try to wake from my phone with an app called "WOL wake on lan" it does not work locally either, but I'll get to that later) Anyway, when the machine is turned on, and I let it 'listen' for incoming magic packets (with a program called "WOL magic packet sender") on my specified port, it does receive them, though when turned off, the machine does not wake. When sending from phone, either locally or via 3G remotely, it does receive but does not wake as well. Because the machine does receive them when turned on and listening, but does not wake when turned off, I am convinced the cause of the problem is my receiving PC, rather than the router or the sender. Some extra info: The receiving machine is a PC running Windows 7 64bit. My router is the Netgear JWNR2000v2. I have the port I use forwarded to my PC's static IP in the router. If anyone could help, or just share your own story with the same problem, maybe we can work this out. Thanks a lot in advance.

• SQL Server 2005 to 2008 DB attach elp please!

  - by Brandon

  I have SQL Server 2005 Standard on my personal machine. I created a very big DB about 21 gb. I made a backup and transferred the .bak file via an ftp program to my dedicated server. I have SQL Server 2008 Enterprise Edition on my dedicated server. I tried restore the transferred .bak file but got an error. I posted the error on here and was told the database is corrupt. How? I don't know. The connection was not interrupted during the ftp transfer. The DB works on my own machine. So then I detached the db on my own machine and transferred the mdf and ldf file to my dedicated server through ftp again and again there were not interruptions. Now I try to attach the db and get this error: The header for file 'DB.mdf' is not a valid database file header. The FILE SIZE property is incorrect. (Microsoft SQL Server, Error: 5172) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=10.00.1442&EvtSrc=MSSQLServer&EvtID=5172&LinkId=20476 I already wasted 21 gb transferring the .bak file. Now I used another 21 to transfer mdf and additional ldf file. Please tell me there's a solution. The db can detach and attach fine on my machine in sql server 2005 but not SQL server 2008 on my server.

• What could cause Windows 7 to hang whenever I install something?

  - by Larsenal

  I've had this problem when installing several different programs (iTunes, Adobe Acrobat Reader just to name two). Regardless of what the program is, the install usually gets at least 90% through the process and then just hangs. I don't see anything bad in the event log besides the following (and this didn't occur exactly at the time of install): wuaueng.dll (964) SUS20ClientDataStore: A request to write to the file "C:\Windows\SoftwareDistribution\DataStore\DataStore.edb" at offset 16252928 (0x0000000000f80000) for 32768 (0x00008000) bytes succeeded, but took an abnormally long time (185 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem. I've run check disk and it passed. I've had some problems with BIOS settings in the past with Windows 7, but I'm not sure whether that could be related. Update... I also see this error in the event log: Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings in either the writer or requestor process.

I see "Previous versions" of c:\ which look like they correspond to the time of attempted installation.

• Windows 8.1 Upgrade: I have to run everything as administrator now?

  - by Robert Dailey

  I was running Windows 8 x64 Professional before and I never had to run programs as administrator to get them to function fully. Examples: Chrome OpenVPN GUI I always have my user under the local "Administrators" group and also disable UAC by putting the slider for it at the very bottom. This always did the trick. After the Windows 8.1 upgrade, I run into a few issues: Running Chrome normally, the Chrome icon doesn't appear in the taskbar. Chrome won't run in the background. OpenVPN GUI has errors when launching. Running both as administrator (Right Click Run as Administrator) fixes those issues and they run perfectly. What has changed in Windows 8.1 upgrade to cause these "problems"? I'm an advanced user, I don't want to have to worry about administrative rights. Any advice on how to fix these problems? EDIT I also get prompted for administrator permission to delete directories under "Program Files" now... that never used to happen before. I can hit Continue and it will allow me to delete, but just another symptom of the problem...

• Linux security: The dangers of executing malignant code as a standard user

  - by AndreasT

  Slipping some (non-root) user a piece of malignant code that he or she executes might be considered as one of the highest security breaches possible. (The only higher I can see is actually accessing the root user) What can an attacker effectively do when he/she gets a standard, (let's say a normal Ubuntu user) to execute code? Where would an attacker go from there? What would that piece of code do? Let's say that the user is not stupid enough to be lured into entering the root/sudo password into a form/program she doesn't know. Only software from trusted sources is installed. The way I see it there is not really much one could do, is there? Addition: I partially ask this because I am thinking of granting some people shell (non-root) access to my server. They should be able to have normal access to programs. I want them to be able to compile programs with gcc. So there will definitely be arbitrary code run in user-space...

• What causes PHP pages to consistently download instead of running normally

  - by Jonathan

  Hi, I'm running a Ubuntu Server on a VM, to test out different web forum solutions. I have set up a ~/public_html/ to be accessible with the apache2 web server, and that works fine. However when I go to a .php file on a browser (using my VM's ip-address/~username/phpfile.php) it does not display it as it should. Instead it offers to save to file/asks what program to open it with. Interestingly though that dialog box does recognise that it is a php file. I have the following version of php installed on the system: PHP 5.3.2-1ubuntu4.5 with Suhosin-Patch (cli) (built: Sep 17 2010 13:49:46) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies And the following server: Server version: Apache/2.2.14 (Ubuntu) Server built: Nov 18 2010 21:19:09 If anyone knows what might be causing this/potential solutions it would make me very happy :) EDIT: Turns out files this behaviour was only apparent on files in the ~/public_html/ directory. All php files in /var/www/ work fine. Prizes go to whoever can explain why? :D (And by prizes I just mean a well done, no actual prizes I'm afraid.)

• Hosting multiple websites from home

  - by dean nolan

  I have just been accepted for Microsofts Wevsite Spark program which I mainly got for the tools, Visual Studio, Blend. I also have a few of my own websites, personal and a couple of business ones. I also work freelance and sometimes I would like a place to just put a demo up of a clients project. The websites I currently have are all on differnet hosting provders and domain registrars. The WebsiteSpark comes with Windows Server 2008 and SQL Server 2008. It would be really advantagous of me to have all these in one place but also so I have complete control over the database and the environment. So I am thinking over the next 4-6 months of migrating all this to my own server that I will host from home, or maybe even setup at home and then store in a proper datacentre. I was wondering what steps I should take and what to be aware of, specifically: 1) having all these different websites on one computer and having the url got to the proper place. 2) Cost effectiveness? Having the server in home as apposed to datacentre. Most solutions I see charge over £1000 a month to have a machine in datacentre. This is mostly for my own ease of management and shared hosting which I currently have is very limited configuration wise. Would getting a server in house be beneficial for then upgrading to the cloud? What measures should I take with my ISP? I know this is a lot I've asked but just even links to good articles would be good. Thanks

• Webcam security camera software that runs as a service

  - by hurfdurf

  I've been looking for Windows webcam software that will run as a Windows service without any user login. The goal is to use the webcam as a cheap security camera and log the results to secure networked storage (windows share, not FTP). The requirements are: Motion detection Video capture Runs as a service (should start recording immediately after reboot) Nice to have: Round-robin storage, e.g. 10Gb limit, oldest files overwritten/deleted when space gets low I've read the other webcam questions but still haven't stumbled across anything suitable. Evaluations thus far: Title MotionDetect Service Snapshots Video SpaceLimit License Yawcam Yes Yes Yes No No GPL WebCam ZoneTrigger Yes No Yes Yes No Commercial Dorgem Yes No Yes Yes No GPL AbelCam Yes No Yes Yes No Commercial Logitech Yes No Yes Yes No Paired with camera IspyConnect Yes No Yes Yes Yes Free SecureCam (SourcefoYes No Yes Yes No GPL AbelCam Yes No Yes Yes No Commercial Active WebCam Yes Yes(?) Yes Yes Volume Free Commercial WebCam Surveyor Yes No Yes Yes No Commercial WebCamsPy NA NA NA NA NA GPL Camera: Logitech Webcam Pro 9000 Windows 7 32-bit WebCamsPy failed to initialize so couldn't be tested So far, the contenders: Active Webcam comes the closest, and claims to run as a service, but i haven't been able to get it to record after a cold boot even though a service is running. Yawcam can be set up as a service but doesn't record video. IspyConnect has exactly the type of space limit I want and looks great, but doesn't run as a service (seems also to be a bit of a cpu hog) Any other suggestions? I'm locked into Windows so can't use linux Motion, which looks almost perfect. Any pointers to rich Windows webcam/motion detection libraries out there that could easily be turned into a command line program would also be appreciated.

• What does opening a serial port do?

  - by reve_etrange

  What does opening the standard PC serial port do, in electrical terms (i.e. what voltages on which pins)? For example, the ancient VB6 program which controls an apparatus I am tasked with maintaining toggles .PortOpen to control some TTL. The connection only used 2 pins (bad solders fell apart), so which pins do I solder to? The only labels / documentation refer to pins 7 and 9, saying 0V and 5V parenthetically, but does .PortOpen really just put 5V between RI and RTS?. As a post script, this isn't the weirdest thing about the set up. The TTL I referred to above also connects to an instrument via a BNC to DB9 (!), with only 1 pin used. I guess there was an assumption about a common ground, since the BNC shielding isn't connected to the GND pin? The connection is to the instrument's 'foot pedal' pin, it was a way to remotely trigger the device. Update According to this page, the DTR and RTS pins can go high when the port is opened. If they were so configured, they will subsequently go low when the port is closed. If DTR and RTS are not enabled, opening the port should set both to low (and keep them low).

• How do I repartition an SDHC card in Windows?

  - by Peter Mortensen

  How do I repartition an SDHC card (4 GB or more)? Do I need third-part tools or Linux (a live CD solution would be OK)? In Windows' Disk Management the option Delete Partition is dimmed out: I can reformat the card as FAT32, copy files to and from the card and even change the file system to NTFS using the command line command CONVERT, but not repartition it. The article How to Partition an SD Card in Windows XP talks about using "a Windows enabler program" which sound rather dubious to me. I have tried to change from “Optimize for quick removal” to “Optimize for performance”. The option to format as NTFS appeared, but the Delete Partition option is still dimmed out. Platform: Windows XP 64-bit SD card reader: USB 2.0 device, LogiLink® CR0005C Cardreader 3,5' USB 2.0 intern 54-in-1 mit USB Front Kingston 16 GB SDHC card, speed class 4. (It could be formatted as FAT32 and successfully used in a 4 GB ReadyBoost setup (Windows 7).) I have also tried on different versions of Windows and with different cards with the same result: Kingston 4 GB SDHC card, speed class 4 (the one shown in the screenshot) Transcend 2 GB (not marked as SDHC, but SD) Windows 7 32-bit (albeit with a somewhat an older card reader) and Windows XP 32-bit on an EliteBook 8730w

• How is network mounted software executed?

  - by CptSupermrkt

  I would like to understand how network mounted software works. For example, at my place of work, we have a software server. Each client machine (hundreds of them) automatically mounts directories from the software server on boot. For example, a program like Matlab is installed just once on the software server, but each client machine can start up an instance of Matlab. What is going on under the hood? Let's say I run /opt/bin/matlab and /opt/ is mounted from the software server, what happens when I press Enter to execute matlab on a client machine? The process is on the client machine, and I've already narrowed down that there isn't any implicit or hidden file transfer (i.e. copying matlab to my machine temporarily for that session) by running matlab on a computer with nearly zero disk space (i.e. not enough room to transfer). Since Matlab was installed on the server, how is my client computer executing it? What mechanism is controlling this? What is happening behind the scenes?

• HAProxy crashes on all requests in 1.5-dev12

  - by Daniel Hough

  I'm having an issue where HAProxy is crashing with no explanation when I switch from 1.4.12 to 1.5-dev12. The reason I'm switching is for the SSL offloading. My config file doesn't have any errors, it's quite simple and it works well with 1.4 - but for some reason when I run it with 1.5-dev12 I see the logs noting that the two backends I have have been set up, and then when I hit one of the frontends, I get an HTTP 400 in the browser and suddenly HAProxy isn't running anymore when I check. I understand that a common workaround to the lack of SSL support for HAProxy is to use Stud, and I may go with that since I am in need of an SSL solution for my service, but before I dele into that world I thought I might see if anybody has experienced the same problems and might know how to fix it. The server is Ubuntu 10.04 and I followed the make instructions on the Exceliance blog here. EDIT: On the advice of Kyle Brandt, I did a bit more investigation. I attached gdb to the haproxy process and when the crash occurred this is what I got: Program received signal SIGSEGV, Segmentation fault. 0x0804e5c2 in dequeue_all_listeners (list=0x9e1a418) at src/protocols.c:184 184 list_for_each_entry_safe(listener, l_back, list, wait_queue) { P.S. HAProxy is awesome, so thank you Exceliance for providing us with something so useful :)
