  • How to prevent response to who-has requests on virtual eth interface?

    - by user42881
    Hi, we use small embedded X86 linux servers equipped with a single physical ethernet port as a gateway for an IP video surveillance application. Each downstream IP cam is mapped to a separate virtual IP address like this: real eth0 IP address= 192.168.1.1, camera 1 (eth0:1) =192.168.1.61, camera 2 (eth0:2) =192.168.1.62, etc. etc. all on the same eth0 physical port. This approach works well, except that a specific third-party windows video recording application running on a separate PC on the same LAN, automatically pings the virtual IPs looking for unique who-has responses on system startup and, when it gets back the same eth0 MAC address for each virtual interface, freaks out and won't allow us to subsequently manually enter those addresses. The windows app doesn't mind, tho, if it receives no answer to the who-has ping. My question - how can we either (a) shut off the who-has responses just for the virtual eth0:x interfaces while keeping them for the primary physical eth0 port, or, in the alternative, spoof a valid but different MAC address for each virtual interface? Thanks!

  • Now Available: Visual Studio 2010 Release Candidate Virtual Machines with Sample Data and Hands-on-L

    - by John Alexander
    From a message from Brian Keller: “Back in December we posted a set of virtual machines pre-configured with Visual Studio 2010 Beta 2, Visual Studio Team Foundation Server 2010 Beta 2, and 7 hands-on-labs. I am pleased to announce that today we have shipped an updated virtual machine using the Visual Studio 2010 Release Candidate bits, a brand new sample application, and 9 hands-on-labs. This VM is customer-ready and includes everything you need to learn and/or deliver demonstrations of many of my favorite application lifecycle management (ALM) capabilities in Visual Studio 2010. This VM is available in the virtualization platform of your choice (Hyper-V, Virtual PC 2007 SP1, and Windows [7] Virtual PC). Hyper-V is highly recommended because of the performance benefits and snapshotting capabilities. Tailspin Toys The sample application we are using in this virtual machine is a simple ASP.NET MVC 2 storefront called Tailspin Toys. Tailspin Toys sells model airplanes and relies on the application lifecycle management capabilities of Visual Studio 2010 to help them build, test, and maintain their storefront. Major kudos go to Dan Massey for building out this great application for us. Hands-on-Labs / Demo Scripts The 9 hands-on-labs / demo scripts which accompany this virtual machine cover several of the core capabilities of conducting application lifecycle management with Visual Studio 2010. Each document can be used by an individual in a hands-on-lab capacity, to learn how to perform a given set of tasks, or used by a presenter to deliver a demonstration or classroom-style training. Unlike the beta 2 release, 100% of these labs target Tailspin Toys to help ensure a consistent storytelling experience. Software quality: Authoring and Running Manual Tests using Microsoft Test Manager 2010 Introduction to Test Case Management with Microsoft Test Manager 2010 Introduction to Coded UI Tests with Visual Studio 2010 Ultimate Debugging with IntelliTrace using Visual Studio 2010 Ultimate Software architecture: Code Discovery using the architecture tools in Visual Studio 2010 Ultimate Understanding Class Coupling with Visual Studio 2010 Ultimate Using the Architecture Explore in Visual Studio 2010 Ultimate to Analyze Your Code Software Configuration Management: Planning your Projects with Team Foundation Server 2010 Branching and Merging Visualization with Team Foundation Server 2010 “ Check out Brian’s Post for more info including download instructions…

  • Windows Azure : Storage Client Exception Unhandled

    - by veda
    I am writing a code for upload large files into the blobs using blocks... When I tested it, it gave me an StorageClientException It stated: One of the request inputs is out of range. I got this exception in this line of the code: blob.PutBlock(block, ms, null); Here is my code: protected void ButUploadBlocks_click(object sender, EventArgs e) { // store upladed file as a blob storage if (uplFileUpload.HasFile) { name = uplFileUpload.FileName; byte[] byteArray = uplFileUpload.FileBytes; Int64 contentLength = byteArray.Length; int numBytesPerBlock = 250 *1024; // 250KB per block int blocksCount = (int)Math.Ceiling((double)contentLength / numBytesPerBlock); // number of blocks MemoryStream ms ; List<string>BlockIds = new List<string>(); string block; int offset = 0; // get refernce to the cloud blob container CloudBlobContainer blobContainer = cloudBlobClient.GetContainerReference("documents"); // set the name for the uploading files string UploadDocName = name; // get the blob reference and set the metadata properties CloudBlockBlob blob = blobContainer.GetBlockBlobReference(UploadDocName); blob.Properties.ContentType = uplFileUpload.PostedFile.ContentType; for (int i = 0; i < blocksCount; i++, offset = offset + numBytesPerBlock) { block = Convert.ToBase64String(BitConverter.GetBytes(i)); ms = new MemoryStream(); ms.Write(byteArray, offset, numBytesPerBlock); blob.PutBlock(block, ms, null); BlockIds.Add(block); } blob.PutBlockList(BlockIds); blob.Metadata["FILETYPE"] = "text"; } } Can anyone tell me how to solve it...

  • Upgrade to Azure 2.2 SDK is causing roles to fail

    - by Jon Leach
    I have 3 worker roles and a web role in my project and I upgraded it to the new 2.2 SDK (required in VS2013). Ever since the upgrade, all of the worker roles are failing and they instantly recycle as soon as they're started. When the roles start, I'm getting these messages: Microsoft.WindowsAzure.ServiceRuntime Information: 200 : Role entrypoint . CALLING OnStart() Microsoft.WindowsAzure.ServiceRuntime Information: 202 : Role entrypoint . COMPLETED OnStart() The thread 0x441c has exited with code 259 (0x103). Microsoft.WindowsAzure.ServiceRuntime Information: 203 : Role entrypoint . CALLING Run() Microsoft.WindowsAzure.ServiceRuntime Warning: 204 : Role entrypoint . COMPLETED Run() ==> ROLE RECYCLING INITIATED Microsoft.WindowsAzure.ServiceRuntime Information: 503 : Role instance recycling is starting The thread 0x2684 has exited with code 259 (0x103) Two things draw my attention: I've started to see a bunch of errors "Cannot find or open the PDB file." But I don't know that this is directly relevant. I'm using VS 2013 and while the project lists the SDK as 2.2, the references within the roles are the 2.1 versions. Do I need to upgrade the components? Why wouldn't the project upgrade these automatically when I pulled the project into VS as it only support 2.2? Any thoughts on how to attach this are appreciated.

  • Azure storage: Uploaded files with size zero bytes

    - by Fabio Milheiro
    When I upload an image file to a blob, the image is uploaded apparently successfully (no errors). When I go to cloud storage studio, the file is there, but with a size of 0 (zero) bytes. The following is the code that I am using: // These two methods belong to the ContentService class used to upload // files in the storage. public void SetContent(HttpPostedFileBase file, string filename, bool overwrite) { CloudBlobContainer blobContainer = GetContainer(); var blob = blobContainer.GetBlobReference(filename); if (file != null) { blob.Properties.ContentType = file.ContentType; blob.UploadFromStream(file.InputStream); } else { blob.Properties.ContentType = "application/octet-stream"; blob.UploadByteArray(new byte[1]); } } public string UploadFile(HttpPostedFileBase file, string uploadPath) { if (file.ContentLength == 0) { return null; } string filename; int indexBar = file.FileName.LastIndexOf('\\'); if (indexBar > -1) { filename = DateTime.UtcNow.Ticks + file.FileName.Substring(indexBar + 1); } else { filename = DateTime.UtcNow.Ticks + file.FileName; } ContentService.Instance.SetContent(file, Helper.CombinePath(uploadPath, filename), true); return filename; } // The above code is called by this code. HttpPostedFileBase newFile = Request.Files["newFile"] as HttpPostedFileBase; ContentService service = new ContentService(); blog.Image = service.UploadFile(newFile, string.Format("{0}{1}", Constants.Paths.BlogImages, blog.RowKey)); Before the image file is uploaded to the storage, the Property InputStream from the HttpPostedFileBase appears to be fine (the size of the of image corresponds to what is expected! And no exceptions are thrown). And the really strange thing is that this works perfectly in other cases (uploading Power Points or even other images from the Worker role). The code that calls the SetContent method seems to be exactly the same and file seems to be correct since a new file with zero bytes is created at the correct location. Does any one have any suggestion please? I debugged this code dozens of times and I cannot see the problem. Any suggestions are welcome! Thanks

    - by Scott Chamberlain
    I am writing a program that will need to communicate to a server through a TS connection. Virtual Channels seems to be exactly what I need but Microsoft's documentation leaves very much to be desired. Does anyone know of good tutorials or just some examples I could use to help me.

  • Making(programming) virtual drives on windows XP

    - by Manux
    Ahoy, I'd like to mount a "virtual drive" myself on Windows XP, I guess using the windows API. What I thought about would be like a server interface, meaning explorer.exe would send "queries", like, list directory, or get file through a pipe or whatever... I know some programs do it, maybe not the way I think it is done, but what the heck, if you know anything, enlighten me please!

  • Preference values - static without tables using a model with virtual attributes

    - by Mike
    Im trying to eliminate two tables from my database. The tables are message_sort_options and per_page_options. These tables basically just have 5 records which are options a user can set as their preference in a preferences table. The preferences table has columns like sort_preferences and per_page_preference which both point to a record in the other two tables containing the options. How can i set up the models with virtual attributes and fixed values for the options - eliminating table lookups every time the preferences are looked up?

  • Writing a Virtual Printer in .NET

    - by David Osborn

  • Windows Azure: Creating a subdirectories inside the blob

    - by veda
    I wanted to create some subdirectories inside my blob. But it is not working out well Here is my code protected void ButUpload_click(object sender, EventArgs e) { // store upladed file as a blob storage if (uplFileUpload.HasFile) { name = uplFileUpload.FileName; // get refernce to the cloud blob container CloudBlobContainer blobContainer = cloudBlobClient.GetContainerReference("documents"); if (textbox.Text != "") { name = textbox.Text + "/" + name; } // set the name for the uploading files string UploadDocName = name; // get the blob reference and set the metadata properties CloudBlockBlob blob = blobContainer.GetBlockBlobReference(UploadDocName); blob.Metadata["FILETYPE"] = "text"; blob.Properties.ContentType = uplFileUpload.PostedFile.ContentType; // upload the blob to the storage blob.UploadFromStream(uplFileUpload.FileContent); } } What I did is that, If I have to create a sub directory, I will enter the name of the sub directory in the textbox. for example, if I need to create a file named "test.txt" inside the sub directory "files" Then, my textbox.text = files and uplFileUpload.FileName = test.txt Now I will concatenate them and upload to the blob.. But it is not working well.. I am getting just https://test.core.windows.net/documents/files/ I am not getting the entire thing I was expecting https://test.core.windows.net/documents/files/test.txt What am I doing wrong... How to create sub directories inside the blob.
