• PPTP VPN connects via NM but goes down during SSH connection

  - by Andrea Olivato

  I setup a VPN PPTP connection via network manager and it connects correctly (I see the lock near the notification icon and the message "Vpn connection has been successfully...") As soon as I try to perform any SSH connection via the established tunnel the connection itself goes down with the message "Vpn connection failed". the SSH connection always fails at debug1: SSH2_MSG_KEXINIT sent I've looked into the system logs and this is the log Dec 12 12:25:00 ushuaia NetworkManager[1155]: <info> Starting VPN service 'pptp'...

• Should I Use PHP as FastCGI?

  - by Synetech inc.

  Hi, I am running an Apache webserver on my Windows machine. It is not generally a public server (most of the little bit of traffic comes from the machine itself, and most of the public traffic comes from crawlers). Basically, it is mostly just for use as a test-bed, development system. I have read about how running PHP as FastCGI is better (ie faster and more stable) than as an Apache module. However, I really don’t like the idea of multiple PHP.exe processes (I don’t like that Apache has two processes and I’m not even too thrilled with Chromium’s multi-process model). So I’m wondering if it would be worthwhile to change PHP to FastCGI for this scenario. If it is, how would I configure it? Pretty much all of the information I have seen has been either for non-Windows or for IIS. As I said, I’m running Windows+Apache. Thanks a lot.

• "Error 1067: The process terminated unexpectedly" when trying to install MySQL on Win7 x64.

  - by Gravitas

  Hi, I've run into a brick wall trying to install MySQL v5.5 on my machine. My PC is Windows 7 x64, Enterprise edition. MySQL installs fine, but when I run the "MySQL Instance Configuration Wizard", it pauses forever on the step "Start Service" (I can let it run for 30 minutes with no response). If I go into services, I see that the "MySQL" service hasn't started, and if I try to start it, it says "Windows could not start MySQL Service on Local Computer. Error 1067: The process terminated unexpectedly." I've tried the following: Turning off firewall. Uninstalling all antivirus software. Installing / reinstalling 32-bit version of MySQL. Installing / reinstalling 64-bit version of MySQL. Uninstalling, deleting the contents of "C:\program files\MySQL" and "C:\program files (x86)\MySQL", reinstalling. Checking to see that there is no rogue services named MySQL???? (from a previous install). Checking that port 3306 is not used by an alternate program. Changing the default port that MySQL uses. Checking for "my.ini" and "my.ini.cnf" in "C:\windows" (nothing there but that can cause a problem). Running both MySQL installer, and configuration wizard, in "Adminstrator mode". Turning off UAC. Installing with defaults, not changing anything. Rebooting my machine (about 6 reboots so far). Opening up port 3306 in the firewall (both TCP and UDP, inbound and outbound). Swearing at the klutz of a programmer who designed MySQL so you can't even install it (as if that would help!) My machine is working 100% in every other way. InfiniDB (a MySQL compatible database) installs 100%, as does Visual Studio 2010, Microsoft SQL Server, etc, etc. Your advice on how to work around this? p.s. Here is the screen it got stuck on for 15 minutes until I killed the process: Update 2010-12-20 Tried MySQL v5.1, it didn't work either. Its amazing - if you type "mysqld /?", or "mysqld -help", it doesn't give you any help. And, if you try to restart the service manually, it doesn't display any error messages. Could it be any more unhelpful? Update 2010-12-21 Installed MySQL 6.0 alpha, and it worked. However, I'd rather not use an alpha release, given that the "stable" release is anything but :( Update 2010-12-21 Found http://dev.mysql.com/doc/refman/5.1/en/windows-troubleshooting.html, dealing with troubleshooting under Windows. Discovered that you can generate an error log if the service doesn't start - see here: http://dev.mysql.com/doc/refman/5.1/en/error-log.html

• Newly installed Ubuntu 12.10 and weird graphics

  - by Benji Marshall

  My machine: 2 GB RAM Intel Pentium Dual core E2180 @ 2 GHz NVIDIA GeForce 6200 LE My friend had recommended Ubuntu to me and I thought I might as well get used to Linux in anticipation for my Raspberry Pi. He said that Wubi was the easiest way to install and I installed it using Wubi. On my first ever boot up of Ubuntu from the Windows Bootloader started normally, and I logged on in a normal fashion, and my desktop loaded normally. I then pressed the Windows key/Power key and everything went wrong. Random lines of yellow and blue appeared on my screen, and changed location when I moved my mouse. The lines stayed for a few seconds and then partially went to I could sort of use my computer. I tried moving my mouse and the entire desktop looked like it broke apart, fragments of it just scatter across my screen at random angles. I could move my mouse and the pointer would move but clicking did nothing. I had to turn off my machine by removing the plug. I would love to get off Windows, but at least the doesn't completely mess up the graphics, and is relatively usable. Please help me solve this....

• permission denied when trying to execute a binary I burned to a CD-R

  - by user16654

  On a UBUNTU karmic machine, I burned a cd from the command prompt using: cdrecord -v speed=16 dev=0,1,0 /FPS.iso The CD now contains an executable and some files. I tested the cd by loading it onto another machine (Red Hat 5.3) and when I try to run the program I get the following message: bash: ./FPS1_1: Permission denied I can open other files like text documents (the executable also comes with shared libraries). I realized I had burned the cd as root so I burned another one as another user but I still got the same problem. How can I remove this permission or what is the problem? P.S. the image was in / if that helps

• Remove Clutter from the Opera Speed Dial Page

  - by Asian Angel

  Do you want to clean up the Speed Dial page in Opera so that only the thumbnails are visible? Today we show you a couple of tweaks that will make it happen. Speed Dial Page The search bar and text at the bottom take up room and add clutter to the look and feel of Opera’s Speed Dial page. Changing the Settings Two small tweaks to the config settings will clean it all up. To get started type opera:config into the address bar and press enter. Type “speed” into the quick find bar and look for the Speed Dial State entry. Change the 1 to 2 and click save. You will see the following message concerning the changes…click OK. Next type “search” into the quick find bar and look for the Speed Dial Search Type entry. Remove all of the text in the blank and click save. Once again you will see a message about the latest change that you have made. At this point you may need to restart Opera for both changes to take full effect. There will be a noticeable difference in how the Speed Dial page looks afterwards and is much cleaner without the Search bar and text field. You will also still be able to access the right click context menu just like before. Conclusion If you have been looking to get a cleaner and less cluttered Speed Dial page in Opera, then these two little hacks will get the job done!

• Upgarde from Asp.Net MVC 1 to MVC 2 - how to and issues with JsonRequestBehavior

  - by Renso

  Goal Upgrade your MVC 1 app to MVC 2 Issues You may get errors about your Json data being returned via a GET request violating security principles - we also address this here. This post is not intended to delve into why the Json GET request is or may be an issue, just how to resolve it as part of upgrading from MVC1 to 2. Solution First remove all references from your projects to the MVC 1 dll and replace it with the MVC 2 dll. Now update your web.config file in your web app root folder by simply changing references to assembly="System.Web.Mvc, Version 1.0.0.0 to Version 2.0.0.0, there are a couple of references in your config file, here are probably most of them you may have:         <compilation debug="true" defaultLanguage="c#">             <assemblies>                        <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />             </assemblies>         </compilation>           <pages masterPageFile="~/Views/Masters/CRMTemplate.master" pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validateRequest="False">             <controls>                 <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" />   Secondly, if you return Json objects from an ajax call via the GET method you ahve several options to fix this depending on your situation: 1. The simplest, as in my case I did this for an internal web app, you may simply do:             return Json(myObject, JsonRequestBehavior.AllowGet);   2. In Mvc if you have a controller base you could wrap the Json method with:         public new JsonResult Json(object data)         {             return Json(data, "application/json", JsonRequestBehavior.AllowGet);                    }   3. The most work would be to decorate your Actions with:         [AcceptVerbs(HttpVerbs.Get)]   4. Another tnat is also a lot of work that needs to be done to every ajax call returning Json is:                             msg = $.ajax({ url: $('#ajaxGetSampleUrl').val(), dataType: 'json', type: 'POST', async: false, data: { name: theClass }, success: function(data, result) { if (!result) alert('Failure to retrieve the Sample Data.'); } }).responseText;   This should cover all the issues you may run into when upgrading. Let me kow if you run into any other ones.

• Recovering text files in terminal using grep on Mac OS X Snow Leopard

  - by littlejim84

  I foolishly removed some source code from my Mac OS X Snow Leopard machine with rm -rf when doing something with buildout. I want to try and recover these files again. I haven't touched the system since to try and seek an answer. I found this article and it seems like the grep method is the way to go, but when running it on my machine I'm getting 'Resource busy' when trying to run it on the disk. I'm using this command: sudo grep -a -B1000 -A1000 'video_output' /dev/disk0s2 > file.txt Where 'dev/disk0s2' is what came up when I ran df. I get this when running: grep: /dev/disk0s2: Resource busy I'm not an expert with this stuff, I'm trying my best. Please can anyone help me further? I'm on the verge of losing two days of source code work! Thank you

• How to upgrade a 1.4.3 TortoiseSVN-created repository to 1.6.x?

  - by SiegeX

  A few years ago, TortoiseSVN 1.4.3 was deployed to our software development team and we are now looking at upgrading the client to the latest 1.6.x version. I had hoped this upgrade would be transparent with the additional features and modifications being client-side. For the most part, this was true except for a very important feature -- merging. When I try to merge a feature branch back into truck I get a show-stopping "Merge tracking not supported error." Here are some facts worth noting: When the repo was first created (before I was on board), it was created via the TortoiseSVN client itself. We do not have a 'svn server daemon' per se, rather the repository folders/database resides on a share folder that is accessible from our workstation machines via file:///. This was actually an eye opener for me, I had always thought there was some SVN server daemon we were talking to. We do not have any access to the underlying machine hosting the SVN share other than the ability to read/write to the share itself. I don't even know what OS the machine is running on. This share server was chosen because its drives are backed up nightly by our IT group. In all honesty, we really don't need the merge tracking feature although it would be nice to have. For the time being it would be sufficient to be able to use a 1.6.x TortoiseSVN client on the 1.4.3 repository and have it merge (sans tracking) without error. So now the question becomes, how does one upgrade a client-created 1.4.3 repo to a 1.6.x compatible version without access to the underlying machine the repo resides on? I was hoping the TortoiseSVN client itself had the ability to do this but that does not appear to be the case. Will I be forced to copy the entire repo over to my local drive, run some svn commands to upgrade the repo locally then copy the repo back to the share point? If so, will doing this break any compatibility with the the 1.4.3 clients in case we cant upgrade them all at the same time? Thanks for the help.

• Finding day of week in batch file? (Windows Server 2008)

  - by Daniel Magliola

  I have a process I run from a batch file, and i only want to run it on a certain day of the week. Is it possible to get the day of week? All the example I found, somehow rely on "date /t" to return "Friday, 12/11/2009", however, in my machine, "date /t" returns "12/11/2009". No weekday there. I've already checked the "regional settings" for my machine, and the long date format does include the weekday. The short date format doesn't, but i'd really rather not change that, since it'll affect a bunch of stuff I do. Any ideas here? Thanks! Daniel

• Why did my laptop turn off?

  - by darenw

  Normally I can slip my running laptop into a backpack, go somewhere, and if it's no more than about half an hour later, it'll still be running. At the destination I plug in the AC power unit and all is well. I run it off of the AC unit before and after the trip, have the screen at less than full backlight brightness, and don't have any peripherals that burn power. Sometimes the wireless switch accidentally slides in the backpack, and that causes extra power to be used and the laptop dies before I reach the destination. Sad, but so be it. But sometimes the wireless switch is off, I've reached the destination in less than 30 minutes (typically 10-20 min), and I know the battery was fully charged, yet the machine is off. Is there a way to determine, after the fact, why the machine shut itself off? I'm running Linux on a fairly powerful Gateway with 4GB RAM, fancy nvidia graphics, dual core cpu, chosen more for number crunching power than battery life, but should last easily for half an hour if not an hour.

• Stuck With grub rescue> console

  - by rej santos

  Here is the background of my issue: I just recently installed the latest version of Ubuntu along side with Windows 8 Enterprise. However upon checking the disk size, it seems that some of the portions of the hd memory were gone so I decided to check the disk partition and have seen that is was being used by another file system. Thinking that the Ubuntu takes it boots stuff from my drive C: , I deleted that partition and formated so I can use it to store some movies, music etc. Now, as I switch on my machine, I am stucked with: error: unknown filesystem grub rescue> I googled a lot and saw the following command which seems no to me like sudo, chainloader etc, all of these command only returns unknown command in the console. What I just wanted is to boot from my Windows 8 OS. Just to add, I can't open the BIOS menu so I could choose what media to boot. As I open my machine it automatically takes me to grub rescue console. Here are the thing I already have: Ubuntu Installation Disk Windows 8 System repair Disk I just don't know how to boot into these things. Let me know what to do.

• chrome memory and cpu footprint

  - by nmizar

  I've searched the forums for an answer but I couldn't find quite the answer I was looking for [1] , so I thought I it could as well be of interest to more people around here. I carry out a big part of my job on the browser (or for the browser, if you want to put it that way). I tend to use Chrome, because it's got natively many of the newest features that I need (DevTools stuff, mainly but not only). BTW, I'm usually running the last available Chrome version/build on a desktop Vaio with 4GB RAM and dual core CPU and Ubuntu 12.04 as distro and Gnome as window manager. So, I was curious about a) why does Chrome spawn so many threads even opening only three of four tabs and b) is there any way to allocate more memory to Chrome to prevent its performance from degrading? Thanks in advance, Nacho PS [1] I found threads about Chrome freezing or running out of memory but not about the reasons for this being so or for avoiding it to happen. PPS Of course, I could always buy a newer and more capable machine and that is exactly what I'm trying to evaluate: is this a question of outdated hardware or the problem will keep appearing on any (decently but not hugely sized) machine?

• Why are network printers not available in the Add Printer Wizard...when run over a network?

  - by Kev

  From a Windows 2003 server machine I browsed the network to an XP client (\computername in Explorer) then double-clicked Printers and Faxes and then Add Printer. In the wizard, normally the second screen asks if you want to install a local printer or a network printer. Well, in this case, it seems to assume I want a local printer, because the second screen is what would normally be the third screen if you chose local printer and clicked Next. I want to install a network printer on a remote machine for its local users. Is this not possible? If not, why not?

• How can I make gitosis distinguish between two users with the same username

  - by bryan kennedy

  I have a gitosis system that seems to be working correctly except for a common problem we run into where I can't distingush permissions between two users who have the same username, but different hosts. For example: [email protected] 's SSH key is in the key folder. And so is [email protected] 's SSH is also in the key folder. These two jsmith's are two different people on two different computers. However, when I configure them in the gitosis.conf file with the usernames jsmith@computer or jsmith@machine, it seems like each user just gets the same permission. Can gitosis not distinguish the full username (name and host)? If not, how do I deal with multiple users accessing our system with common usernames? Thanks for any help.

• MapReduce

  - by kaleidoscope

  MapReduce is a programming model and an associated implementation for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of  intermediate key/value pairs, and a reduce function that merges all intermediate values associated with the same intermediate key. Many real world tasks are expressible in this model, as shown in the paper. Programs written in this functional style are automatically parallelized and executed on a large cluster of commodity machines. The run-time system takes care of the details of partitioning the input data,  scheduling the program's execution across a set of machines, handling machine failures, and managing the required inter-machine communication. This allows programmers without any experience with parallel and distributed systems to easily utilize the resources of a large distributed system. Example: A process to count the appearances of each different word in a set of documents void map(String name, String document):   // name: document name   // document: document contents   for each word w in document:     EmitIntermediate(w, 1); void reduce(String word, Iterator partialCounts):   // word: a word   // partialCounts: a list of aggregated partial counts   int result = 0;   for each pc in partialCounts:     result += ParseInt(pc);   Emit(result); Here, each document is split in words, and each word is counted initially with a "1" value by the Map function, using the word as the result key. The framework puts together all the pairs with the same key and feeds them to the same call to Reduce, thus this function just needs to sum all of its input values to find the total appearances of that word.   Sarang, K

• problem in exporting a partition on a usb stick as nfs volume

  - by Bond

  I have a USB disk which has 2 partitions.I exported one of them (on NFS) and now I am trying to mount it at client machine.

• Is a matching entry in /etc/hosts required for hostname?

  - by JohnWoltman

  I was installing a Tomcat webapp that refused to work until I stumbled on someone else's issue with an unrelated product. The solution was to add the machine's name to /etc/hosts, to match the name returned by hostname. Is this required for general Linux networking to function correctly? My webapp is running in a virtual machine so that I can test the webapp, and I don't normally bother with the /etc/hosts file on VMs. I just shook my fist and cursed Tomcat and webapp's behavior. I read http://serverfault.com/questions/118823, but that doesn't say if it's required or not.
