  • Ubuntu 12.04 VPN default route issue when using the UI

    - by Pieter Pabst
    When setting up a VPN connection using the UI (System settings = Network) the VPN connection is used as the default route after connecting to it. How can I avoid this? That is without assigning manual addresses. I want the connection to use DHCP. It should use the eth* interfaces for my default route, like they are used before making the connection. The VPN route should only be used when connecting to addresses in the ppp0 adapters range. If possible using the UI only, not that I'm not used to editing config files... But the point of using Ubuntu for me was the "it just works" concept (which is true for 99% of the time, keep up the good work). I tried setting the "Method" combobox in the "Configure..." dialogue to "Automatic (VPN) addresses only". That doesn't make a difference. (Another thing I noticed; the UI shows my connection as a "Wireless connection" in the list control on the left. Don't know why... it has the right icon, but that's probably something for the bug tracker)

    I have installed Ubuntu 12.04/ 32-bit using Wubi on my laptop running dual with windows 7 desktop and it works very very well. I am now also trying to install Ubuntu on another laptop already running a linux operating system only but not successful in doing so. Would like to install Windows 7 dual with Ubuntu. At the moment it is complaining about partitions of the existing linux when trying to install Windows 7 which I suppose is fair. Please herewith assist in installing the Ubuntu and Windows 7 platforms. Very much appreciated.

  • How should I host our scalable worker processes?

    - by Pieter Breed
    We are designing a new architecture for an enterprise business. The principles we've followed so far is not to develop what you can (possible buy and) deploy, ie, don't reinvent any wheels. In this way we've decided on CQRS, RabbitMQ, Riak and a bunch of other things. We still need to write /some/ business code though and these will be in the form of worker processes, which will consume commands from a message queue and after any side-effects, produce events onto another message queue. The idea behind this is that via the competing-consumers design we will have a scalable design right out of the box. One option is of writing a management infrastructure that will know how to: deploy code instantiate processes kill processes update configuration etc IE provide fault tolerance and scalability. Also, this is exactly what something like GAE and Heroku does for you, but in a public setting and in our organization, public is bad. My question is, is there an out-of-the-box solution that we can use to host our consumers in? Like a private cloud or private platform-as-a-service. Private Heroku or GAE. Is there some kind of software or software product with which we can do all of these things and thereby get scalability and fault tolerance over our consumers?

  • How do I trust an off site application

    - by Pieter
    I need to implement something similar to a license server. This will have to be installed off site at the customers' location and needs to communicate with other applications at the customers' site (the applications that use the licenses) and an application running in our hosting center (for reporting and getting license information). My question is how to set this up in a way I can trust that: The license server is really our application and not something that just simulates it; and There is no "man in the middle" (i.e. a proxy or something that alters the traffic). The first thing I thought of was to use with client certificates and that would solve at least 2. However, what I'm worried about is that someone just decompiles (this is build in .NET) the license server, alters some logic and recompiles it. This would be hard to detect from both connecting applications. This doesn't have to be absolutely secure since we have a limited number of customers whom we have a trust relationship with. However, I do want to make it more difficult than a simple decompile/recompile of the license server. I primarily want to protect against an employee or nephew of the boss trying to be smart.

  • this.BoundingBox.Intersects(Wall[0].BoundingBox) not working properly

    - by Pieter
    I seem to be having this problem a lot, I'm still learning XNA / C# and well, trying to make a classic paddle and ball game. The problem I run into (and after debugging have no answer) is that everytime I run my game and press either of the movement keys, the Paddle won't move. Debugging shows that it never gets to the movement part, but I can't understand why not? Here's my code: // This is the If statement for checking Left movement. if (keyboardState.IsKeyDown(Keys.Left) || keyboardState.IsKeyDown(Keys.A)) { if (!CheckCollision(walls[0])) { Location.X -= Velocity; } } //This is the CheckCollision(Wall wall) boolean public bool CheckCollision(Wall wall) { if (this.BoundingBox.Intersects(wall.BoundingBox)) { return true; } return false; } As far as I can tell there should be absolutely no problem with this, I initialize the bounding box in the constructor whenever a new instance of Walls and Paddle is created. this.BoundingBox = new Rectangle(0, 0, Sprite.Width, Sprite.Height); Any idea as to why this isn't working? I have previously succeeded with using the whole Location.X < Wall.Location.X + Wall.Texture.Width code... But to me that seems like too much coding if a simple boolean check could be done.

  • OpenVPN performance: how many concurrent clients are possible?

    - by Steffen Müller
    I am evaluating a system for a client where many OpenVPN clients connect to a OpenVPN server. "Many" means 50000 - 1000000. Why do I do that? The clients are distributed embedded systems, each sitting behind the system owners dsl router. The server needs to be able to send commands to the clients. My first naive approach is to make the clients connect to the server via an openvpn network. This way, the secure communication tunnel can be used in both directions. This means that all clients are always connected to the server. There are many clients summing up over the years. The question is: does the OpenVPN server explode when reaching a certain number of clients? I am already aware of a maximum TCP connection number limit, therefore (and for other reasons) the VPN would have to use UDP transport. OpenVPN gurus, what is your opinion?

  • Create an image of a pure Ubuntu-Installation on Macbook Pro

    - by Stefan Müller
    I'm running Ubuntu 11.10 on my Macbook Pro (Late 2009) as the only operating system, so theres's no Mac OS X oder Bootcamp installed. It runs fine and now i'd like to create an image of the current installation. Unfortunately my Acronis True Image cd doesn't boot on this device and my attempts to create an image with partimage or dd from a bootable ubuntu live cd to a external hd failed ("can't read from block 0"). Are there any others out there with such an installation and if yes: how did you succeed in imaging your partition/device?

  • Default sort order in Windows folder

    - by Florian Müller
    I am running Windows 7 and I have a folder "Dropbox" inside my Documents folder. However, every time I restart Explorer and enter this folder, it is sorted by mutation date. I'd like to have it default sorted by name, which is still default in all other folders, however not in this one. Please let me know if there is a way to define this properly! Thanks in advance! Note: I actually found out that this is in every folder or library now, not only in some folders. This is the standard sort behaviour when I open explorer the first time.

  • AJAX POST problems with CKFinder

    - by Muller
    We're using CKFinder for one of our sites, which has been working fine for us until we moved to a new dedicated server (which is similar but not exactly the same as the old server). Now we cant upload, the AJAX request simply never finishes. From monitoring it in Firebug it attempts to POST to here: http://www.site.com/temp/ckfinder/core/connector/php/connector.php?command=FileUpload&type=Files&currentFolder=%2F&hash=4f9cdbbb1e295966&langCode=en&= but never gets a response. This is the same CKFinder install on both WIMP servers, one works fine one doesnt. any idea where we should be looking to fix this problem? php.ini maybe? any help would be great as we havent a clue at this stage.

  • TLFTextfield broken after upgrading from CS5 to CS5.5

    - by Ashley Muller
    For my project I am using the following: FlashDevelop 3.3.4 RTM Flash Pro CS 5 (libraries only, no code) Some time ago we started using TLFTextfields. One of the things I had to do was include the tlfruntime.swc file from the Adobe Flash CS 5 folder in the FlashDevelop project. Note that I copied this file to the project folder and included it, I didn't just include the file straight from the CS5 path. I have since been given a new computer that has Flash CS 5.5. I recompiled one of my swf libraries in CS 5.5, and now when I run the program, I get: Illegal override of createTextLine in flashx.textLayout.compose.ComposeState I figure the tlfruntime.swc being included in the FlashDevelop project is out of date and needs to be updated with the one from CS 5.5. So I copied the tlfruntime.swc from the CS 5.5 path, include it in the FlashDevelop project (instead of the older file), but now I get this: Illegal override of softKeyboardActivatingHandler in fl.text.container.TLFContainerController. Can anyone assist with what else I need to do to get TLFTextfields working again in CS 5.5?

  • nhibernate - mapping with contraints

    - by Tobias Müller
    Hello everybody, I am having a Problem with my nhibernate-mapping and I can't find a solution by searching on stackoverflow/google/documentation. The database I am using has (amongst others) two tables. One is unit with the following fields: id enduring_id starts ends damage_enduring_id [...] The other one is damage, which has the following fields: id enduring_id starts ends [...] The units are assigned to a damage and one damage can have zero, one or more units working on it. Every time a unit moves to annother damage, the dataset is copied. The field "ends" of the old record and "starts" of the new record are set to the current time stamp, enduring_id stays the same. So if I want to know which units were working on a damage at a certain time, I do the following select: select * from unit join damage on damage.enduring_id = unit.damage_enduring_id where unit.starts <= 'time' and unit.ends = 'time' (This is not an actualy query from the database, I made it up to make clear what I mean. The the real database is a little more complex) Now I want to map it that way, so I can load all the damages which are valid at one time (starts <= wanted time <= ends) and that each of them has a Bag with all the attached units at that time (again starts <= wanted time <= ends). Is this possible within the mapping? Sorry if this is a stupid question, but I am pretty new to nhibernate and I have no clue how to do it. Thanks a lot for reading my post! Bye, Tobias

  • PHP CLI Application on Debian: why can't I output a line break?

    - by Steffen Müller
    Hello! I have a really puzzling problem: I am writing a PHP CLI application running on a debian server. I am connected to the server via SSH, just the normal way. Everything runs as usual. Except the following: echo "My CLI fun\n\n"; echo "Is this."; Outputs on the SSH terminal, when executing the PHP script: My CLI funIs this. I am really puzzled as I have never had such a problem. The bash behaves normal in all other aspects. I already tried to output chr(10) and such, same problem. Does anybody have a clue?

  • Create Outlines around line.

    - by Eric Muller
    Hi SO community! I am drawing graphs into a WinForms Picturebox. Now I am searching for a possibility to 'duplicate' a line (an array of points), so that the two resulting lines are positioned a fixed distance away from the original one. Like in this picture, I have the red line and want to get the black ones: I thought about just moving the line a few pixels up/right/up-right, but that leads to strange overlapping lines. Is there any other approach that does what I want? Any ideas would be greatly appreciated. Thanks!

  • Flash - can't access classes in another SWF

    - by Ashley Muller
    Hi, I'm trying to load a local SWF file and use the classes in that SWF (its a code only SWF, nothing in library). Here's the code that loads the library: var AD:ApplicationDomain = ApplicationDomain.currentDomain; var context:LoaderContext = new LoaderContext(false, AD); SA_gamecore_loader = new Loader(); SA_gamecore_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onGameCoreLibraryDataComplete); SA_gamecore_loader.load(new URLRequest("GameCore.swf"), context); Here's the code that tries to instantiate a class from GameCore.swf: var test:Class = GetClassFromDefinition("MenuArt") as Class; var testInstance:Object = new test(); public function GetClassFromDefinition(theStr:String):Object { var theClass:Object; try { theClass = GameCoreLibraryData.applicationDomain.getDefinition(theStr); } catch(e:ReferenceError) { trace(e); return null; } return theClass; } And this is the message that's traced: ReferenceError: Error #1065: Variable MenuArt is not defined. The GameCore.swf is in the same location as the parent swf. I'm using Flash Develop if that helps. Anyone able to point out what I'm doing wrong?

  • Terminal Server 2008 not issuing Volume device CAL's

    We've a lot of Volume Licences left, but the License Server apparantly doesn't use them. Instead it issues Temporary Per Device CAL's. Which is a bit odd off course... There are two licensing servers installed on terminal servers, not on a domain controller (these are pushed by SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\LicenseServers registry setting) EDIT: http://img180.imageshack.us/img180/8927/ss20090909135547.png

  • Google Chrome doesn't want to access Facebook

    - by Pieter van Niekerk
    I have been experiencing a bit of a problem with Chrome over the last couple of days where it doesn't want to access Facebook. When I open Chrome it works fine for a while and then if I were to refresh the page it would give me the Chrome 'This webpage is not available' message. This webpage is not available Google Chrome could not load the webpage because www.facebook.com took too long to respond. The website may be down, or you may be experiencing issues with your Internet connection. Here are some suggestions: Reload this webpage later. Check your Internet connection. Restart any router, modem, or other network devices you may be using. Add Google Chrome as a permitted program in your firewall's or antivirus software's settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again. If you use a proxy server, check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server, adjust your proxy settings: Go to the wrench menu Options Under the Hood Change proxy settings... LAN Settings and deselect the "Use a proxy server for your LAN" checkbox. This problem only persists when using the proxy and doesn't occur at all when not on the proxy. I have also tried different browsers (IE9 and Firefox 9.01) but it doesn't occur in any of them. This problem goes away for a while when I restart Chrome, only to happen again a couple of minutes later. I have tried deleting the cookies for Facebook without restarting Chrome, but to no avail. I am using Windows7 with Chrome 17
