  • Can Subject Alternative Name accommodate multiple virtual mail domains?

    - by Lawrence
    I am currently running a postfix server with self signed certificates serving one mail domain, mycompany.com, the mail server is mail.mycompany.com and so is the CN of the certificate. Now, I need to add a new domain to it. The new domain name is mycompany.net to the same server. Since the users already have the root of the old certificate, I'd like to reuse that. However, I'd like to issue a new certificate so users using the SMTP from Outlook/Thunderbird of mail.mycompany.net do not get warnings. If I understand correctly, if I issue a new certificate with CN=mail.mycompany.com and a subjectAltName=DNS:mail.mydomain.net and have postfix serve this, the client will not complain either way about the cn not matching the target host name. Am I correct in this assumption or am I misunderstanding the concept of Subject Alternative Name? Just to avoid conversation, I do not want to have users on mycompany.net addresses use the mycompany.com server because I might (not a technical issue) have to split up into two different locations, and I want to produce an easily migrateable setup.

  • When does /tmp get cleared?

    - by John Lawrence Aspden
    I'm taking to putting various files in /tmp, and I wondered what the rules on deleting them are? I'm imagining it's different for different distributions, and I'm particularly interested in Ubuntu and Fedora desktop versions. But a nice general way of finding out would be a great thing. Even better would be a nice general way of controlling it! (Something like 'every day at 3 in the morning, delete any /tmp files older than 60 days, but don't clear the directory on reboot')

  • Cannot open SQL 2005 database in SQL server Management Studio 2008 R2 on Windows 7

    - by Darryl Lawrence
    I have Windows 7 64bit as my OS + SQL Server 2008 R2 installed. I can connect to SQL Databases (2008), but cannot connect to a SQL 2005 database. I can, however, connect to the 2005 SQL Database on a PC that has Windows XP as the OS and also has SQL Server 2008 R2 installed. So it seems that it works fine on XP but not on Windows 7 (32 or 64bit). is this an Operating System issue? Error message: Cannot connect to OMRSQLV016\PRODSQL002. =================================== A network-related or instance-specific error occurred while establishing a connection to SQL Server.

  • Windows Server vs Sharing

    - by Mark Lawrence
    Not sure if this is the right place for this question. I have a friend that owns a small business running 3 local machines, that are connected to the internet, and a server that each local machine connects to. He has recently bought a newer server, and by server I mean a Windows Vista box. He wants to use this purely to store data that the 3 local machines can access, kind of like a glorified external hard drive. Im suggesting to fore-go the server option and simply setup sharing on the 'server' box. Interested in hearing any suggestions as to whether the server idea is preferable?

  • Nginx rewrite rules, some work, some don't

    - by Lawrence Goldstien
    Here are the two rewrite rules: This one works rewrite ^/knowledgebase/([0-9]+)/[a-z0-9_-]+.html$ /./knowledgebase.php?action=displayarticle&id=$1 last; This one doesn't rewrite ^/announcements/([0-9]+)/[a-z0-9_-]+.html$ /./announcements.php?id=$1 last; There is no difference between the two as far as I can see. The url to be rewritten for announcements is: /announcements/2/New-Site-Design.html And should be rewritten to: /announcements.php?id=2 I really can't see how the announcements one doesn't work compared to the knowledgebase one. Any tips would be greatly appreciated.

  • HTTPS subdomain does not load site under HTTP

    - by Mark Lawrence
    I recently installed an SSL certificate on a subdomain following the steps at cPanel. Lets just say the domain is example.com and the subdomain is sub.example.com. I updated the userdata file for the subdomain and changed the IP address to the IP I wanted to use I updated the example.com zone file and changed the IP for the A Name for the subdomain to the IP I wanted to use Using domain tools I checked that sub.example.com resolved to the new IP which it does. I then installed an SSL certificate on example.com and then on sub.example.com When I visit http://sub.example.com I get the default Apache account screen, and when I visit https://sub.example.com I get the cPanel 404 page. If however I enter https://sub.example.com/admin (the location of my admin section) the page loads and I can login. I thought that this might be a propagation issue however as the subdomain resolves to the IP and I can reach the admin page I suspect it is not a propagation issue and possibly an incorrect zone file. Any thoughts?

  • Html.EditorFor, Html.DisplayFor not working on MVC1.0 -> MVC2.0 manual migration

    - by lawrence-chase
    Has anyone encountered this problem? I manually migrated a MVC1.0 application to MVC2.0 and everything so far seems to be working fine. Today I wanted to try out the Html.EditorFor helper and it doesn't render the template. I set it up the same way in a fresh MVC2.0 application and the template does render. Is there anything other (or specifically needed when mirgrating to activate this behavior) than throwing the partial view like DateTime.ascx into Views/Shared/EditorTemplates and using the helper methods to render the model objects? I'm stumped.

  • IOException reading from HttpWebResponse response stream over SSL

    - by Lawrence Johnston
    I get the following exception when attempting to read the response from my HttpWebRequest: System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream. at System.Net.ConnectStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.IO.StreamReader.ReadBuffer() at System.IO.StreamReader.ReadToEnd() ... My code functions without issue when using http. I am talking to a third-party device; I do not have access to the server code. My code is as follows: private string MakeRequest() { // Disable SSL certificate verification per // http://www.thejoyofcode.com/WCF_Could_not_establish_trust_relationship_for_the_SSL_TLS_secure_channel_with_authority.aspx ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; }); Uri uri = new Uri("https://mydevice/mypath"); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.Method = WebRequestMethods.Http.Get; using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { using (Stream responseStream = response.GetResponseStream()) { using (StreamReader sr = new StreamReader(responseStream.)) { return sr.ReadToEnd(); } } } } Does anybody have any thoughts about what might be causing it?

  • Is it possible to force the WCF test client to accept a self-signed certificate?

    - by Lawrence Johnston
    I have a WCF web service running in IIS 7 using a self-signed certificate (it's a proof of concept to make sure this is the route I want to go). It's required to use SSL. Is it possible to use the WCF Test Client to debug this service without needing a non-self-signed certificate? When I try I get this error: Error: Cannot obtain Metadata from https:///Service1.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

  • Recommendations on resolving a cs1705 error

    - by Scott A. Lawrence
    I'm upgrading a number of solutions from Visual Studio 2008 to Visual Studio 2010RC. In the process of doing this, I've encountered two instances of compiler error cs1705, one for System.Core and another for System.Data.Linq. In each case, an assembly compiled earlier has a reference to the .NET 4.0 version of these system assemblies, while the web project I'm trying to compile only has references to the .NET 3.5 version of them. Adding .NET 4.0 versions of System.Core and System.Data.Linq to the web project doesn't resolve the error. Removing the .NET 3.5 versions of the assemblies so that only the .NET 4.0 versions remain results in even more errors. Any recommendations on how to resolve this error would be greatly appreciated.

  • Connection Error using NHibernate 3.0 with Oracle

    - by Olu Lawrence
    I'm new to NHibernate. My first attempt is to configure and establish connection to Oracle 11.1g using ODP. For this test, I use a test fixture, but I get the following error: Inner exception: "Object reference not set to an instance of an object." Outer exception: Could not create the driver from NHibernate.Driver.OracleDataClientDriver. The test script is shown below: using IBCService.Models; using NHibernate.Cfg; using NHibernate.Tool.hbm2ddl; using NUnit.Framework; namespace IBCService.Tests { [TestFixture] public class GenerateSchema_Fixture { [Test] public void Can_generate_schema() { var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly(typeof(Product).Assembly); var fac = new SchemaExport(cfg); fac.Execute(false, true, false); } } } The exception occurs at the last line: fac.Execute(false, true, false); The NHibernate config is shown: <?xml version="1.0" encoding="utf-8"?> <!-- This config use Oracle Data Provider (ODP.NET) --> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" > <session-factory name="IBCService.Tests"> <property name="connection.driver_class"> NHibernate.Driver.OracleDataClientDriver </property> <property name="connection.connection_string"> User ID=TEST;Password=test;Data Source=//RAND23:1521/RAND.PREVALENT.COM </property> <property name="connection.provider"> NHibernate.Connection.DriverConnectionProvider </property> <property name="show_sql">false</property> <property name="dialect">NHibernate.Dialect.Oracle10gDialect</property> <property name="query.substitutions"> true 1, false 0, yes 'Y', no 'N' </property> <property name="proxyfactory.factory_class"> NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu </property> </session-factory> </hibernate-configuration> Now, if I change the NHibernate.Driver.OracleDataClientDriver to NHibernate.Driver.OracleClientDriver (Microsoft provider for Oracle), the test succeed. Once switched back to Oracle provider, whichever version, the test fails with the error stated earlier. I've spent 3 days already trying to figure out what is not in order without success. I hope someone out there could provide useful info on what I am doing wrong.

  • Why does this CSS example use "height: 1%" with "overflow: auto"?

    - by Lawrence Lau
    I am reading a HTML and CSS book. It has a sample code of two-column layout. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <style> #main {height: 1%; overflow: auto;} #main, #header, #footer {width: 768px; margin: auto;} #bodycopy { float: right; width: 598px; } #sidebar {margin-right: 608px; } #footer {clear: both; } </style> </head> <body> <div id="header" style='background-color: #AAAAAA'>This is the header.</div> <div id="main" style='background-color: #EEEEEE'> <div id="bodycopy" style='background-color: #BBBBBB'> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> </div> <div id="sidebar" style='background-color: #CCCCCC'> This is the sidebar. </div> </div> <div id="footer" style='background-color: #DDDDDD'>This is the footer.</div> </body> </html> The author mentions that the use of overflow auto and 1% height will make the main area expand to encompass the computed height of content. I try to remove the 1% height and tried in different browsers but they don't show a difference. I am quite confused of its use. Any idea?

  • Android Tile Bitmap

    - by Rich Lawrence
    I'm trying to load a bitmap in Android which I want to tile. I'm currently using the following in my view to display a bitmap: canvas.drawBitmap(bitmap, srcRect, destRect, null) I essentially want to use this bitmap as a background image in my app and would like to repeat the bitmap in both the X and Y directions. I've seen the TileMode.REPEAT constant for the BitmapShader class but am unsure if this is to do with repeating he actual bitmap or to do with applying a filter to the bitmap.

  • Making my site login "mirror" Facebook login

    - by lawrence
    I've noticed that Huffington Post does this: if you log out of there, it forces you to log out of Facebook as well, and if you log in on Facebook and go back to Huffington Post, it automatically logs you in there as well. Is this a straightforward use of the FB Connect API that I just haven't noticed, or is there some trick?

  • Why not use development provisioning instead of ad hoc?

    - by lawrence
    I was under the impression that when you use a development provisioning profile for a build of an app, only the specified developers can deploy that build to a phone. But I just deployed a build that uses a development profile to a phone using Xcode Organizer, even though I'm not one of the valid developers for that profile. One of my colleagues, also not a valid developer, did the same with his phone using iTunes. In that case, why not use a development provisioning profile for distributing your app to e.g. your QA team, instead of ad hoc distribution?

  • Recursive Syntax in Oslo

    - by Kevin Lawrence
    I'm writing my first DSL with Oslo and I am having a problem with a recursive syntax definition. The input has sections which can contain questions or other sections recursively (composite pattern) like this: Section: A Question: 1 Question: 2 Section: B Question: 1 End End My definition for a Section looks like this syntax Section = "Section:" id:Text body:(SectionBody)* "End Section"; Which works (but doesn't handle recursive sections) if I define SectionBody like this syntax SectionBody = (Question); but doesn't work with a recursive definition like this syntax SectionBody = (Question | Section); What am I missing?

  • Saving complex aggregates using Repository Pattern

    - by Kevin Lawrence
    We have a complex aggregate (sensitive names obfuscated for confidentiality reasons). The root, R, is composed of collections of Ms, As, Cs, Ss. Ms have collections of other low-level details. etc etc R really is an aggregate (no fair suggesting we split it!) We use lazy loading to retrieve the details. No problem there. But we are struggling a little with how to save such a complex aggregate. From the caller's point of view: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r); Our competing solutions are: Dirty flags Each entity in the aggregate in the aggregate has a dirty flag. The save() method in the repository walks the tree looking for dirty objects and saves them. Deletes and adds are a little trickier - especially with lazy-loading - but doable. Event listener accumulates changes. Repository subscribes a listener to changes and accumulates events. When save is called, the repository grabs all the change events and writes them to the DB. Give up on repository pattern. Implement overloaded save methods to save the parts of the aggregate separately. The original example would become: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r.Ps); repository.save(r.Cs); repository.save(r.Ms); (or worse) Advice please! What should we do?

  • What's the best Mac custom disk image creation app?

    - by Lawrence Johnston
    I'm looking for a custom disk image creation app that I can integrate into the build process for my app (which means I need to be able to run it from the command line if possible). My desired features are that it will size the image for me, let me set the location of my icons when the image is opened, set a custom background/icon, etc. Free would be nice but if there's something that does exactly what I need I'll pay for it.

  • How do I disable zoom on control-scroll in Visual Studio 2010?

    - by Lawrence Johnston
    Visual Studio 2010 adds a zoom setting on the bottom left of the text editor (to the left of the horizontal scroll bar) and also adopts the control + mouse scroll idiom for zooming in and out. The former is fine, but I dislike the latter as I am occasionally still holding control when I start scrolling my source code (which results in the text size radically changing and completely throwing me off whatever I was doing). How do I disable it?
