  • PHP include() through HTTP makes Apache time out

    - by Adam Interact
    I have a problem with ExpressionEngine2 after moving from an old server to WHM/cPanel running on CentOS6.4. Simple test code to reproduce that issue: <?php $protocol = strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') === FALSE ? 'http' : 'https'; $host = $_SERVER['HTTP_HOST']; include($protocol . '://' . $host . '/header.html'); ?> <p> Main text...</p> <?php include($protocol . '://' . $host . '/footer.html'); ?> Where header.html looks like <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> and footer.html looks like: </body> </html> Creates Apache time out: Warning: include(http://www.domain.com/header.html) [function.include]: failed to open stream: Connection timed out in /home/domain/public_html/test/index.php on line 5 Warning: include() [function.include]: Failed opening 'http://www.domain.com/header.html' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/domain/public_html/test/index.php on line 5 Main text...

  • Courier IMAP always disconnects since update

    - by Raffael Luthiger
    Since one of our customers updated their server courier does not handle IMAP connections properly any more. POP3 works without any problems. When I try to test IMAP with telnet then it is always like this: $ telnet domain.com 143 Trying 188.40.46.214... Connected to domain.com. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready.

There is no other message. And in no other log file I've checked I could find any other related message. The system was updated from Ubuntu 10.10 to 12.04. How could I get more information? Or does anybody have an idea what could go wrong here?

  • How make rewrite rules relative to .htaccess file.

    - by Kendall Hopkins
    Current I have an .htaccess file like this. RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f [OR] RewriteCond %{REQUEST_URI} ^/(always|rewrite|these|dirs)/ [NC] RewriteRule ^(.*)$ router.php [L,QSA] It works create when the site files are in the document_root of the webserver (ie. domain.com/abc.php - /abc.php). But in our current setup (which isn't changeable), this isn't ensured. We can sometimes have arbitrary folder in between the document root and folder of the .htaccess file (ie. domain.com/something/abc.php - /something/abc.php). The only problem with is that is the second RewriteCond no longer works. Is there anyway to dynamically check if the accessed path by a path relative to .htaccess file. For Example: If I have a site where domain.com/rewrite/ is the directory of the .htaccess file. NOT FORCED TO REWRITE -> domain.com/rewrite/index.php FORCED TO REWRITE -> domain.com/rewrite/rewrite/index.php If I have a site where domain.com/ is the directory of the .htaccess file. NOT FORCED TO REWRITE -> domain.com/index.php FORCED TO REWRITE -> domain.com/rewrite/index.php

  • SSH multi-hop connections with netcat mode proxy

    - by aef
    Since OpenSSH 5.4 there is a new feature called natcat mode, which allows you to bind STDIN and STDOUT of local SSH client to a TCP port accessible through the remote SSH server. This mode is enabled by simply calling ssh -W [HOST]:[PORT] Theoretically this should be ideal for use in the ProxyCommand setting in per-host SSH configurations, which was previously often used with the nc (netcat) command. ProxyCommand allows you to configure a machine as proxy between you local machine and the target SSH server, for example if the target SSH server is hidden behind a firewall. The problem now is, that instead of working, it throws a cryptic error message in my face: Bad packet length 1397966893. Disconnecting: Packet corrupt Here is an excerpt from my ~/.ssh/config: Host * Protocol 2 ControlMaster auto ControlPath ~/.ssh/cm_socket/%r@%h:%p ControlPersist 4h Host proxy-host proxy-host.my-domain.tld HostName proxy-host.my-domain.tld ForwardAgent yes Host target-server target-server.my-domain.tld HostName target-server.my-domain.tld ProxyCommand ssh -W %h:%p proxy-host ForwardAgent yes As you can see here, I'm using the ControlMaster feature so I don't have to open more than one SSH connection per-host. The client machine I tested this with is an Ubuntu 11.10 (x86_64) and both proxy-host and target-server are Debian Wheezy Beta 3 (x86_64) machines. The error happens when I call ssh target-server. When I call it with the -v flag, here is what I get additionally: OpenSSH_5.8p1 Debian-7ubuntu1, OpenSSL 1.0.0e 6 Sep 2011 debug1: Reading configuration data /home/aef/.ssh/config debug1: Applying options for * debug1: Applying options for target-server.my-domain.tld debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: auto-mux: Trying existing master debug1: Control socket "/home/aef/.ssh/cm_socket/[email protected]:22" does not exist debug1: Executing proxy command: exec ssh -W target-server.my-domain.tld:22 proxy-host.my-domain.tld debug1: identity file /home/aef/.ssh/id_rsa type -1 debug1: identity file /home/aef/.ssh/id_rsa-cert type -1 debug1: identity file /home/aef/.ssh/id_dsa type -1 debug1: identity file /home/aef/.ssh/id_dsa-cert type -1 debug1: identity file /home/aef/.ssh/id_ecdsa type -1 debug1: identity file /home/aef/.ssh/id_ecdsa-cert type -1 debug1: permanently_drop_suid: 1000 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.0p1 Debian-3 debug1: match: OpenSSH_6.0p1 Debian-3 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.8p1 Debian-7ubuntu1 debug1: SSH2_MSG_KEXINIT sent Bad packet length 1397966893.

  • Plesk: Spamassassin ignores emails to redirected accounts

    - by Mat
    When I set up email redirects within Plesk 9.5, Spamassassin ignores all emails sent to the redirected address and only scans emails that are sent directly to the address which has a mailbox. Steps to reproduce Set up two mail accounts: [email protected] as a proper email account with a mailbox and [email protected] with all emails redirected to [email protected]. (It doesn't make a difference, if [email protected] has a mailbox enabled or not.) [email protected] -> [email protected] Set up the spam filter on both accounts. I set mine to delete spam right away, but you can just keep the default ("mark as spam"). Now, when you send an emails to [email protected], it will have Spamassassins tags in the email header, but when you send emails to [email protected], they will end up in the same mailbox but will have no spamassassin tags in the emails header and they will not be scanned. Other notes I am using Plesk 9.5.4 on Ubuntu 8.04 LTS with the default Qmail. I've observed this bug since Plesk 8, but I can't stand it any more and would appreciate any hack or fix.

  • EventID 1058 Code 5, Sysvol is subdir of Sysvol - how to fix?

    - by nulliusinverba
    I have been trying to resolve this error, like many others: The processing of Group Policy failed. Windows attempted to read the file \domain.local\SysVol\domain.local\Policies{3EF90CE1-6908-44EC-A750-F0BA70548600}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following: a) Name Resolution/Network Connectivity to the current domain controller. b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller). c) The Distributed File System (DFS) client has been disabled. Error code: 5 = Access Denied. The incredibly helpful post is this one (http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/A_1073-Diagnosing-and-repairing-Events-1030-and-1058.html). Quoting from this post: HERE IS A LIST OF POTENTIAL PROBLEMS THAT CAN LEAD TO 1030 AND 1058 EVENT ERRORS: --Sometimes the permissions of the file folders that contain Group policies (the Sysvol folder) can be corrupted. --Sometimes you have problems with NetBIOS: --Sometimes the GPO itself is corrupt, or you have a partial set of data for that GPO. --Sometimes you may have problems with File Replication Services, which almost always indicates a problem with DNS --Sysvol may be a subfolder of itself: Sysvol/Sysvol I have the problem listed where sysvol is a subfolder of sysvol. The directory structure is: -sysvol -domain -staging -staging areas -sysvol (shared as "\\server\sysvol") -domain.local -ClientAgent -Policies -scripts Interestingly, the second sysvol folder is the one that is shared as "\server\sysvol". This makes me confident this is the issue with the permissions and error code 5. Also interestingly, my server 2008 R2 servers can see it fine - my server 2008 servers cannot, and get the error. This is consistent across all my servers. This latter fact makes me uncertain what I need to do to fix this up. Do I, e.g., simply move the shared sysvol folder up a level to replace the non-shared one? Any help greatly appreciated. Cheers, Tim.

  • User authentication -- username mismatch in IIS in ASP.NET application

    - by Cory Larson
    Last week, an employee's Active Directory username was changed (or a new one was created for them). For the purposes of this example, let's assume these usernames: Old: Domain\11111 New: Domain\22222 When this user now logs in using their new username, and attempts to browse to any one of a number of ASP.NET applications using only Windows Authentication (no Anonymous enabled), the system authenticates but our next layer of database-driven permissions prevents them from being authorized. We tracked it down to a mismatch of usernames between their logon account and who IIS thinks they are. Below are the outputs of several ASP.NET variables from apps running in a Windows 2008 IIS7.5 environment: Request.ServerVariables["AUTH_TYPE"]: Negotiate Request.ServerVariables["AUTH_USER"]: Domain\11111 Request.ServerVariables["LOGON_USER"]: Domain\22222 Request.ServerVariables["REMOTE_USER"]: Domain\11111 HttpContext.Current.User.Identity.Name: Domain\11111 System.Threading.Thread.CurrentPrincipal.Identity.Name: Domain\11111 From the above, I can see that only the LOGON_USER server variable has the correct value, which is the account the user used to log on to their machine. However, we use the "AUTH_USER" variable for looking up the database permissions. In a separate testing environment (completely different server: Windows 2003, IIS6), all of the above variables show "Domain\22222". So this seems to be a server-specific issue, like the credentials are somehow getting cached either on their machine or on the server (the former seems more plausible). So the question is: how do I confirm whether it's the user's machine or the server that is botching the request? How should I go about fixing this? I looked at the following two resources and will be giving the first one a try shortly: http://www.interworks.com/blogs/jvalente/2010/02/02/removing-saved-credentials-passwords-windows-xp-windows-vista-or-windows-7 http://stackoverflow.com/questions/2325005/classic-asp-request-servervariableslogon-user-returning-wrong-username/5299080#5299080 Thanks.

  • In Stud, which Private RSA Key should be concatenated in the x509 SSL certificate pem file to avoid "self-signed" browser warning?

    - by Aaron
    I'm trying to implement Stud as an SSL termination point before HAProxy as a proof of concept for WebSockets routing. My domain registrar Gandi.net offers free 1-year SSL certs. Through OpenSSL, I generated a CSR which gave me two files: domain.key domain.csr I gave domain.csr to my trusted authority and they gave me two files: domain.cert GandiStandardSSLCA.pem (I think this is referred to as the intermediary cert?) This is where I encountered friction: Stud, which uses OpenSSL, expects there to be an "rsa private key" in the "pem-file" - which it describes as "SSL x509 certificate file. REQUIRED." If I add the domain.key to the bottom of Stud's pem-file, Stud will start but I receive the browser warning saying "The certificate is self-signed." If I omit the domain.key Stud will not start and throws an error triggered by an OpenSSL function that appears intended to determine whether or not my "pem-file" contains an "RSA Private Key". At this point I cannot determine whether the problem is: Free SSL cert will always be self-signed and will always cause browser to present warning I'm just not using Stud correctly I'm using the wrong "RSA private key" The CA domain cert, the intermediary cert, and the private key are in the wrong order.

  • Make nginx config like apache2 virtualhosts

    - by user2104070
    I have web server with apache2 with many subdomains on it like, domain.com, abc.domain.com, def.domain.com etc. etc. Now I got a new nginx server and want to set it up like apache2, so to test I created configs (2 files in /etc/nginx/sites-available/ and link to them from sites-enabled/) as shown, domain.config: server { listen 80 default_server; listen [::]:80 default_server ipv6only=on; root /srv/www/; index index.html index.htm; # Make site accessible from http://localhost/ server_name domain.com; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri/ =404; } } abc-domain config: server { listen 80; listen [::]:80; root /srv/www/tmp1/; index index.html index.htm; # Make site accessible from http://localhost/ server_name abc.domain.com; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri/ =404; } } but when I access with domain.com I am getting index.html from /var/www/tmp1 only. Is there something I'm doing wrong in the nginx config?

  • DNS redirecting to Apache

    - by leo
    I have CentOS installed on LVM, that is on Debian. There are BIND and Apache on CentOS. I need to access sites from browser on Debian with names like: 1.domain, 2.domain, etc. So I set up Apache and I can access these sites, but using /etc/hosts/ on Debian. And now I'm trying to configure bind. named.conf: zone "domain" IN { type master; file "/var/named/domain.zone"; allow-update { none; }; }; 192.168.100.1 is DNS' ip; 192.168.100.139 is Apache ip; domain.zone: $TTL 86400 @ IN SOA domain. root.domain.

  • exchange server 2010 with multiple domains

    - by air
    i have one exchange server 2010, which is working fine with one domain. my exchange is working as follows pop3 collector collect emails from one master catchall account and then deliver to exchange server, this working perfect. now what i want to add another domain to same exchange, i have added new domain as trusted domain & email policy and this new domain email account works fine with internal emails. now what i have done, i again forward new email account to same catchall account. but if i send email from any other external email address email is bounce, i can see email receive by pop3 collector but bounce by exchange server. to make you more clear let me explain logic on which i am working. i have 2 domains 1. domain1.com ([email protected]) 2. domain2.com ([email protected] -->[email protected]) now on my machine with exchange server i have pop3 collector which collect all emails from [email protected] and forward to exchange 2010 server. all emails to domain1.com is working perfect but when i send email to [email protected] this email redirect to [email protected] perfectly but when exchanger server receive this email, it bounce. i have also study the url link text and follow the whole process but no success. i also check that my DNS/MX is working fine as the bounce message is going from my exchange server. EDIT the only problem is with accepted domain, as email come to exchange server then bounce back. i just try this today i create one user called test, then i goto his properties -- email there was only one email account [email protected] i try to send email to [email protected] from internet (email bounce) then again i go to test user properties -- email and Add one email [email protected] again u try to send email to t*[email protected]* from internet (email received) i think the only problem is with accepted domain but in hub transport , it shows accepted is there any way to check does domain is properly accepted or not in exchange 2010 server.

  • How can I find which logon script is being run?

    - by user2517266
    I'm having an issue with network drives. Suddenly some computers and users aren't getting their mapped network drives from the logon script. I am NOT a domain admin, I don't have permission to login to the domain controller. And I know very little about Active Directory. The issue seems random, some users this day, different users tomorrow. Some computers run fine and some won't map no matter who logs in. They are mixed OS's XP (SP3), Vista, and 7. I was looking at the domain in windows explorer and I have found the batch file(s) that maps the drives in several locations, how do I know which one is actually being ran? The .bat file is located in \DOMAIN\NETLOGON\script.bat and \DOMAIN\SYSVOL\DOMAIN\scripts\script.bat and \DOMAIN\SYSVOL\DOMAIN\policies\GUID(Right? It's a crazy string)\User\Scripts\Logon\script.bat So, how can I figure out which one is actually being ran per computer or user? Cause they are all slightly different from each other and one of them doesn't map properly. Do all the files in NETLOGON get ran? Cause there are 15+ files in there. Or is it specified in Group Policy which one(s) get ran? EDIT: I am able to access a program called Active Directory Users and Computers, but the properties tab for any user is blank for the logon script.

  • Inheritance Mapping Strategies with Entity Framework Code First CTP5 Part 1: Table per Hierarchy (TPH)

    - by mortezam
    A simple strategy for mapping classes to database tables might be “one table for every entity persistent class.” This approach sounds simple enough and, indeed, works well until we encounter inheritance. Inheritance is such a visible structural mismatch between the object-oriented and relational worlds because object-oriented systems model both “is a” and “has a” relationships. SQL-based models provide only "has a" relationships between entities; SQL database management systems don’t support type inheritance—and even when it’s available, it’s usually proprietary or incomplete. There are three different approaches to representing an inheritance hierarchy: Table per Hierarchy (TPH): Enable polymorphism by denormalizing the SQL schema, and utilize a type discriminator column that holds type information. Table per Type (TPT): Represent "is a" (inheritance) relationships as "has a" (foreign key) relationships. Table per Concrete class (TPC): Discard polymorphism and inheritance relationships completely from the SQL schema.I will explain each of these strategies in a series of posts and this one is dedicated to TPH. In this series we'll deeply dig into each of these strategies and will learn about "why" to choose them as well as "how" to implement them. Hopefully it will give you a better idea about which strategy to choose in a particular scenario. Inheritance Mapping with Entity Framework Code FirstAll of the inheritance mapping strategies that we discuss in this series will be implemented by EF Code First CTP5. The CTP5 build of the new EF Code First library has been released by ADO.NET team earlier this month. EF Code-First enables a pretty powerful code-centric development workflow for working with data. I’m a big fan of the EF Code First approach, and I’m pretty excited about a lot of productivity and power that it brings. When it comes to inheritance mapping, not only Code First fully supports all the strategies but also gives you ultimate flexibility to work with domain models that involves inheritance. The fluent API for inheritance mapping in CTP5 has been improved a lot and now it's more intuitive and concise in compare to CTP4. A Note For Those Who Follow Other Entity Framework ApproachesIf you are following EF's "Database First" or "Model First" approaches, I still recommend to read this series since although the implementation is Code First specific but the explanations around each of the strategies is perfectly applied to all approaches be it Code First or others. A Note For Those Who are New to Entity Framework and Code-FirstIf you choose to learn EF you've chosen well. If you choose to learn EF with Code First you've done even better. To get started, you can find a great walkthrough by Scott Guthrie here and another one by ADO.NET team here. In this post, I assume you already setup your machine to do Code First development and also that you are familiar with Code First fundamentals and basic concepts. You might also want to check out my other posts on EF Code First like Complex Types and Shared Primary Key Associations. A Top Down Development ScenarioThese posts take a top-down approach; it assumes that you’re starting with a domain model and trying to derive a new SQL schema. Therefore, we start with an existing domain model, implement it in C# and then let Code First create the database schema for us. However, the mapping strategies described are just as relevant if you’re working bottom up, starting with existing database tables. I’ll show some tricks along the way that help you dealing with nonperfect table layouts. Let’s start with the mapping of entity inheritance. -- The Domain ModelIn our domain model, we have a BillingDetail base class which is abstract (note the italic font on the UML class diagram below). We do allow various billing types and represent them as subclasses of BillingDetail class. As for now, we support CreditCard and BankAccount: Implement the Object Model with Code First As always, we start with the POCO classes. Note that in our DbContext, I only define one DbSet for the base class which is BillingDetail. Code First will find the other classes in the hierarchy based on Reachability Convention. public abstract class BillingDetail  {     public int BillingDetailId { get; set; }     public string Owner { get; set; }             public string Number { get; set; } } public class BankAccount : BillingDetail {     public string BankName { get; set; }     public string Swift { get; set; } } public class CreditCard : BillingDetail {     public int CardType { get; set; }                     public string ExpiryMonth { get; set; }     public string ExpiryYear { get; set; } } public class InheritanceMappingContext : DbContext {     public DbSet<BillingDetail> BillingDetails { get; set; } } This object model is all that is needed to enable inheritance with Code First. If you put this in your application you would be able to immediately start working with the database and do CRUD operations. Before going into details about how EF Code First maps this object model to the database, we need to learn about one of the core concepts of inheritance mapping: polymorphic and non-polymorphic queries. Polymorphic Queries LINQ to Entities and EntitySQL, as object-oriented query languages, both support polymorphic queries—that is, queries for instances of a class and all instances of its subclasses, respectively. For example, consider the following query: IQueryable<BillingDetail> linqQuery = from b in context.BillingDetails select b; List<BillingDetail> billingDetails = linqQuery.ToList(); Or the same query in EntitySQL: string eSqlQuery = @"SELECT VAlUE b FROM BillingDetails AS b"; ObjectQuery<BillingDetail> objectQuery = ((IObjectContextAdapter)context).ObjectContext                                                                          .CreateQuery<BillingDetail>(eSqlQuery); List<BillingDetail> billingDetails = objectQuery.ToList(); linqQuery and eSqlQuery are both polymorphic and return a list of objects of the type BillingDetail, which is an abstract class but the actual concrete objects in the list are of the subtypes of BillingDetail: CreditCard and BankAccount. Non-polymorphic QueriesAll LINQ to Entities and EntitySQL queries are polymorphic which return not only instances of the specific entity class to which it refers, but all subclasses of that class as well. On the other hand, Non-polymorphic queries are queries whose polymorphism is restricted and only returns instances of a particular subclass. In LINQ to Entities, this can be specified by using OfType<T>() Method. For example, the following query returns only instances of BankAccount: IQueryable<BankAccount> query = from b in context.BillingDetails.OfType<BankAccount>() select b; EntitySQL has OFTYPE operator that does the same thing: string eSqlQuery = @"SELECT VAlUE b FROM OFTYPE(BillingDetails, Model.BankAccount) AS b"; In fact, the above query with OFTYPE operator is a short form of the following query expression that uses TREAT and IS OF operators: string eSqlQuery = @"SELECT VAlUE TREAT(b as Model.BankAccount)                       FROM BillingDetails AS b                       WHERE b IS OF(Model.BankAccount)"; (Note that in the above query, Model.BankAccount is the fully qualified name for BankAccount class. You need to change "Model" with your own namespace name.) Table per Class Hierarchy (TPH)An entire class hierarchy can be mapped to a single table. This table includes columns for all properties of all classes in the hierarchy. The concrete subclass represented by a particular row is identified by the value of a type discriminator column. You don’t have to do anything special in Code First to enable TPH. It's the default inheritance mapping strategy: This mapping strategy is a winner in terms of both performance and simplicity. It’s the best-performing way to represent polymorphism—both polymorphic and nonpolymorphic queries perform well—and it’s even easy to implement by hand. Ad-hoc reporting is possible without complex joins or unions. Schema evolution is straightforward. Discriminator Column As you can see in the DB schema above, Code First has to add a special column to distinguish between persistent classes: the discriminator. This isn’t a property of the persistent class in our object model; it’s used internally by EF Code First. By default, the column name is "Discriminator", and its type is string. The values defaults to the persistent class names —in this case, “BankAccount” or “CreditCard”. EF Code First automatically sets and retrieves the discriminator values. TPH Requires Properties in SubClasses to be Nullable in the Database TPH has one major problem: Columns for properties declared by subclasses will be nullable in the database. For example, Code First created an (INT, NULL) column to map CardType property in CreditCard class. However, in a typical mapping scenario, Code First always creates an (INT, NOT NULL) column in the database for an int property in persistent class. But in this case, since BankAccount instance won’t have a CardType property, the CardType field must be NULL for that row so Code First creates an (INT, NULL) instead. If your subclasses each define several non-nullable properties, the loss of NOT NULL constraints may be a serious problem from the point of view of data integrity. TPH Violates the Third Normal FormAnother important issue is normalization. We’ve created functional dependencies between nonkey columns, violating the third normal form. Basically, the value of Discriminator column determines the corresponding values of the columns that belong to the subclasses (e.g. BankName) but Discriminator is not part of the primary key for the table. As always, denormalization for performance can be misleading, because it sacrifices long-term stability, maintainability, and the integrity of data for immediate gains that may be also achieved by proper optimization of the SQL execution plans (in other words, ask your DBA). Generated SQL QueryLet's take a look at the SQL statements that EF Code First sends to the database when we write queries in LINQ to Entities or EntitySQL. For example, the polymorphic query for BillingDetails that you saw, generates the following SQL statement: SELECT  [Extent1].[Discriminator] AS [Discriminator],  [Extent1].[BillingDetailId] AS [BillingDetailId],  [Extent1].[Owner] AS [Owner],  [Extent1].[Number] AS [Number],  [Extent1].[BankName] AS [BankName],  [Extent1].[Swift] AS [Swift],  [Extent1].[CardType] AS [CardType],  [Extent1].[ExpiryMonth] AS [ExpiryMonth],  [Extent1].[ExpiryYear] AS [ExpiryYear] FROM [dbo].[BillingDetails] AS [Extent1] WHERE [Extent1].[Discriminator] IN ('BankAccount','CreditCard') Or the non-polymorphic query for the BankAccount subclass generates this SQL statement: SELECT  [Extent1].[BillingDetailId] AS [BillingDetailId],  [Extent1].[Owner] AS [Owner],  [Extent1].[Number] AS [Number],  [Extent1].[BankName] AS [BankName],  [Extent1].[Swift] AS [Swift] FROM [dbo].[BillingDetails] AS [Extent1] WHERE [Extent1].[Discriminator] = 'BankAccount' Note how Code First adds a restriction on the discriminator column and also how it only selects those columns that belong to BankAccount entity. Change Discriminator Column Data Type and Values With Fluent API Sometimes, especially in legacy schemas, you need to override the conventions for the discriminator column so that Code First can work with the schema. The following fluent API code will change the discriminator column name to "BillingDetailType" and the values to "BA" and "CC" for BankAccount and CreditCard respectively: protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) {     modelBuilder.Entity<BillingDetail>()                 .Map<BankAccount>(m => m.Requires("BillingDetailType").HasValue("BA"))                 .Map<CreditCard>(m => m.Requires("BillingDetailType").HasValue("CC")); } Also, changing the data type of discriminator column is interesting. In the above code, we passed strings to HasValue method but this method has been defined to accepts a type of object: public void HasValue(object value); Therefore, if for example we pass a value of type int to it then Code First not only use our desired values (i.e. 1 & 2) in the discriminator column but also changes the column type to be (INT, NOT NULL): modelBuilder.Entity<BillingDetail>()             .Map<BankAccount>(m => m.Requires("BillingDetailType").HasValue(1))             .Map<CreditCard>(m => m.Requires("BillingDetailType").HasValue(2)); SummaryIn this post we learned about Table per Hierarchy as the default mapping strategy in Code First. The disadvantages of the TPH strategy may be too serious for your design—after all, denormalized schemas can become a major burden in the long run. Your DBA may not like it at all. In the next post, we will learn about Table per Type (TPT) strategy that doesn’t expose you to this problem.

  • Silverlight Tree View with Multiple Levels

    - by psheriff
    There are many examples of the Silverlight Tree View that you will find on the web, however, most of them only show you how to go to two levels. What if you have more than two levels? This is where understanding exactly how the Hierarchical Data Templates works is vital. In this blog post, I am going to break down how these templates work so you can really understand what is going on underneath the hood. To start, let’s look at the typical two-level Silverlight Tree View that has been hard coded with the values shown below: <sdk:TreeView>  <sdk:TreeViewItem Header="Managers">    <TextBlock Text="Michael" />    <TextBlock Text="Paul" />  </sdk:TreeViewItem>  <sdk:TreeViewItem Header="Supervisors">    <TextBlock Text="John" />    <TextBlock Text="Tim" />    <TextBlock Text="David" />  </sdk:TreeViewItem></sdk:TreeView> Figure 1 shows you how this tree view looks when you run the Silverlight application. Figure 1: A hard-coded, two level Tree View. Next, let’s create three classes to mimic the hard-coded Tree View shown above. First, you need an Employee class and an EmployeeType class. The Employee class simply has one property called Name. The constructor is created to accept a “name” argument that you can use to set the Name property when you create an Employee object. public class Employee{  public Employee(string name)  {    Name = name;  }   public string Name { get; set; }} Finally you create an EmployeeType class. This class has one property called EmpType and contains a generic List<> collection of Employee objects. The property that holds the collection is called Employees. public class EmployeeType{  public EmployeeType(string empType)  {    EmpType = empType;    Employees = new List<Employee>();  }   public string EmpType { get; set; }  public List<Employee> Employees { get; set; }} Finally we have a collection class called EmployeeTypes created using the generic List<> class. It is in the constructor for this class where you will build the collection of EmployeeTypes and fill it with Employee objects: public class EmployeeTypes : List<EmployeeType>{  public EmployeeTypes()  {    EmployeeType type;            type = new EmployeeType("Manager");    type.Employees.Add(new Employee("Michael"));    type.Employees.Add(new Employee("Paul"));    this.Add(type);     type = new EmployeeType("Project Managers");    type.Employees.Add(new Employee("Tim"));    type.Employees.Add(new Employee("John"));    type.Employees.Add(new Employee("David"));    this.Add(type);  }} You now have a data hierarchy in memory (Figure 2) which is what the Tree View control expects to receive as its data source. Figure 2: A hierachial data structure of Employee Types containing a collection of Employee objects. To connect up this hierarchy of data to your Tree View you create an instance of the EmployeeTypes class in XAML as shown in line 13 of Figure 3. The key assigned to this object is “empTypes”. This key is used as the source of data to the entire Tree View by setting the ItemsSource property as shown in Figure 3, Callout #1. Figure 3: You need to start from the bottom up when laying out your templates for a Tree View. The ItemsSource property of the Tree View control is used as the data source in the Hierarchical Data Template with the key of employeeTypeTemplate. In this case there is only one Hierarchical Data Template, so any data you wish to display within that template comes from the collection of Employee Types. The TextBlock control in line 20 uses the EmpType property of the EmployeeType class. You specify the name of the Hierarchical Data Template to use in the ItemTemplate property of the Tree View (Callout #2). For the second (and last) level of the Tree View control you use a normal <DataTemplate> with the name of employeeTemplate (line 14). The Hierarchical Data Template in lines 17-21 sets its ItemTemplate property to the key name of employeeTemplate (Line 19 connects to Line 14). The source of the data for the <DataTemplate> needs to be a property of the EmployeeTypes collection used in the Hierarchical Data Template. In this case that is the Employees property. In the Employees property there is a “Name” property of the Employee class that is used to display the employee name in the second level of the Tree View (Line 15). What is important here is that your lowest level in your Tree View is expressed in a <DataTemplate> and should be listed first in your Resources section. The next level up in your Tree View should be a <HierarchicalDataTemplate> which has its ItemTemplate property set to the key name of the <DataTemplate> and the ItemsSource property set to the data you wish to display in the <DataTemplate>. The Tree View control should have its ItemsSource property set to the data you wish to display in the <HierarchicalDataTemplate> and its ItemTemplate property set to the key name of the <HierarchicalDataTemplate> object. It is in this way that you get the Tree View to display all levels of your hierarchical data structure. Three Levels in a Tree View Now let’s expand upon this concept and use three levels in our Tree View (Figure 4). This Tree View shows that you now have EmployeeTypes at the top of the tree, followed by a small set of employees that themselves manage employees. This means that the EmployeeType class has a collection of Employee objects. Each Employee class has a collection of Employee objects as well. Figure 4: When using 3 levels in your TreeView you will have 2 Hierarchical Data Templates and 1 Data Template. The EmployeeType class has not changed at all from our previous example. However, the Employee class now has one additional property as shown below: public class Employee{  public Employee(string name)  {    Name = name;    ManagedEmployees = new List<Employee>();  }   public string Name { get; set; }  public List<Employee> ManagedEmployees { get; set; }} The next thing that changes in our code is the EmployeeTypes class. The constructor now needs additional code to create a list of managed employees. Below is the new code. public class EmployeeTypes : List<EmployeeType>{  public EmployeeTypes()  {    EmployeeType type;    Employee emp;    Employee managed;     type = new EmployeeType("Manager");    emp = new Employee("Michael");    managed = new Employee("John");    emp.ManagedEmployees.Add(managed);    managed = new Employee("Tim");    emp.ManagedEmployees.Add(managed);    type.Employees.Add(emp);     emp = new Employee("Paul");    managed = new Employee("Michael");    emp.ManagedEmployees.Add(managed);    managed = new Employee("Sara");    emp.ManagedEmployees.Add(managed);    type.Employees.Add(emp);    this.Add(type);     type = new EmployeeType("Project Managers");    type.Employees.Add(new Employee("Tim"));    type.Employees.Add(new Employee("John"));    type.Employees.Add(new Employee("David"));    this.Add(type);  }} Now that you have all of the data built in your classes, you are now ready to hook up this three-level structure to your Tree View. Figure 5 shows the complete XAML needed to hook up your three-level Tree View. You can see in the XAML that there are now two Hierarchical Data Templates and one Data Template. Again you list the Data Template first since that is the lowest level in your Tree View. The next Hierarchical Data Template listed is the next level up from the lowest level, and finally you have a Hierarchical Data Template for the first level in your tree. You need to work your way from the bottom up when creating your Tree View hierarchy. XAML is processed from the top down, so if you attempt to reference a XAML key name that is below where you are referencing it from, you will get a runtime error. Figure 5: For three levels in a Tree View you will need two Hierarchical Data Templates and one Data Template. Each Hierarchical Data Template uses the previous template as its ItemTemplate. The ItemsSource of each Hierarchical Data Template is used to feed the data to the previous template. This is probably the most confusing part about working with the Tree View control. You are expecting the content of the current Hierarchical Data Template to use the properties set in the ItemsSource property of that template. But you need to look to the template lower down in the XAML to see the source of the data as shown in Figure 6. Figure 6: The properties you use within the Content of a template come from the ItemsSource of the next template in the resources section. Summary Understanding how to put together your hierarchy in a Tree View is simple once you understand that you need to work from the bottom up. Start with the bottom node in your Tree View and determine what that will look like and where the data will come from. You then build the next Hierarchical Data Template to feed the data to the previous template you created. You keep doing this for each level in your Tree View until you get to the last level. The data for that last Hierarchical Data Template comes from the ItemsSource in the Tree View itself.

  • A way to return multiple return values from a method: put method inside class representing return value. Is it a good design?

    - by john smith optional
    I need to return 2 values from a method. My approach is as follows: create an inner class with 2 fields that will be used to keep those 2 values put the method inside that class instantiate the class and call the method. The only thing that will be changed in the method is that in the end it will assign those 2 values to the fields of the instance. Then I can address those values by referencing to the fields of that object. Is it a good design and why?

  • How to get my list of rows from database to show while using Zend-Paginator

    - by Matto
    I'm fairly new to the world of Zend-Framework, and have taken over a site that is in zend-framework. There is a bug on one of the pages right now and I can not figure it out. I think it has something to do with Zend Paginator, but not sure. This is the code in the controller for the section I am having a problem with: $currentPage = $this->_getParam('page'); $numWebsitesFullOnline = $websites->getWebsitesFullOnline(); $select = $websites->select(); $select->setIntegrityCheck(false); $select->from(array('w' => 'websites'), array('id', 'online', 'kw_adjective', 'kw_name', 'kw_location', 'url', 'email', 'address', 'ftp_server', 'ftp_username', 'ftp_password', 'ftp_folder', 'phone_number', 'indexed', 'youtube_position', 'twitter_user', 'facebook_id', 'video_made', 'image1_id', 'image2_id', 'image3_id', 'bg_color', 'dark_color', 'light_color', 'links_color', 'text_color', 'google_account', 'ganalytics', 'gmaps_status', 'google_position', 'gmap_position', 'hp1', 'hp2', 'hp3', 'hp4', 'hp5', 'hp6', 'hp7', 'hp8', 'hp9', 'hp10', 'about1_id', 'about2_id', 'about3_id', 'tip1_id', 'tip2_id', 'tip3_id', 'contact_texts_id', 'quote_texts_id', 'demographics_id')) ->join(array('d' => 'demographics'), 'w.demographics_id = d.id', array('total_population')) ->order(array('total_population DESC', 'kw_location')); $paginator = new Zend_Paginator(new Zend_Paginator_Adapter_DbSelect($select)); $paginator->setItemCountPerPage(50); $paginator->setCurrentPageNumber($currentPage); $paginator->setPageRange(($paginator->getTotalItemCount() / 50) + 1); $this->view->paginator = $paginator; $numWebsitesOnline = $websites->getWebsitesOnline(); On the php page I have this code to call the websites that are in the database to a list: <p class="red"> Websites online: <?php echo $this->numOnline; ?> </p> <?php print_r(count($this->paginator)); ?> <?php if(count($this->paginator)): ?> <table class="table-list"> <?php foreach($this->paginator as $item): ?> <tr> <?php if($this->userIsAllowedAction('websites', 'reload')): ?> <td class="center noborder w30"> <img class="hidden" src="<?php echo $this->baseUrl() .

So it sees that there is one row in the websites table of the database, but it is not returning anything to page and listing out the rows in the websites table. Not sure if this is the paginator that is causing this cause it is returning 0 or something else I don't know about.

  • Postfix - suspend domain from which deferred status was received?

Currently my Postfix goes through each address in the queue. Please see the below example. At 09:48:32 the status=deferred appears.

  • How can I find the Windows domain logon name of a user from within Outlook 2010?

    - by Chris Farmer
    I need to figure out someone's login name for our domain, and I'd like to be able to do this from within Outlook 2010. I used to be able to do this from Outlook 2007 by right-clicking the user's name in an email message that they'd sent me, and clicking "Outlook Properties..." in the context menu. That would bring up this dialog, which contained what I need in the "alias" field: Now I've installed Outlook 2010. I want to do the same thing, but I can't seem to find a corresponding field. First, I don't see an explicit "Outlook Properties" menu option anymore, and what I think is the corresponding dialog looks completely different: It seems weird that, although I'm looking at the properties of my own name in the same email message in 2007 and 2010 in these screenshots, my name is shown differently in each -- Chris versus Christopher. That makes me think that Outlook isn't really looking in the same place to get this info in each case. So, can I get that "alias" field from within Outlook 2010?

  • What does "Local Domain Name" on router do and how do I get it to work?

    - by Giovanni Galbo
    I have a D-Link DGL-4500 router. One of the settings is "Local Domain Name," which I have set to local (see screenshot). What I expect is for me to be able to hit my computers via name, e.g. m6.local should resolve to one of my computers; but this isn't happening. I know that I can do this via hosts file, but it would be neat if I could do it via the router... plus I have devices like an iPad that don't let you edit the hosts file. Am I misunderstanding this router feature or am I doing something wrong?

  • How to restrict Apache Location directive to cetain sub-domain?

    - by ohho
    On our server www.example.com, we use the <Location> directive to proxy traffic to a back-end server: <Location /app1> ProxyPass http://192.168.1.20 </Location> Then we added a sub-domain uat.example.com which points to the same IP address of www.example.com. We want to use it as a proxy for client to test an app being developed. Hopefully, the client can access via: http:/uat.example.com/app2_uat Now if we add a Location: <Location /app2_uat> ProxyPass http://192.168.1.30 </Location> The client can access both: http:/www.example.com/app2_uat http:/uat.example.com/app2_uat How can I restrict Location such that only: http:/uat.example.com/app2_uat is accessible? (i.e. http:/www.example.com/app2_uat should not be accessible.)

  • Connecting to Aerohive APs from Laptops running Win. 7 using authentication from a Windows 2008 domain server

    - by user264116
    I have deployed a wireless network using Aerohive access points. 2 of them are set up as radius servers. I want my users to be able to use the same user name and password they use when they log onto our domain. They are able to do this from android devices or computers running Windows 8. It will not work on Windows 7 machines. How do I remedy this situation, keeping in mind that the machines are personal machines not company owned and I will have no way to change their hardware or software.

  • Log into another XP machine's SQL Server with a different userid? (WORKGROUP, not domain)

    - by Eric H.
    I have two machines at home, both XP Pro SP3. I have no domain controller, so they're both just in WORKGROUP. How can I, using Windows Authentication, log into an instance of SQL Server running on the other machine? Whenever I try it, it seems to try to login as 'Guest', even though I have entered the machine name (OTHER-DESKTOP), and login (OTHER-DESKTOP\otheruser) in the User Accounts Control Panel box. It works fine if I use sql server name and password, so I know the server is running. Any clues?

  • In a multi-domain forest, what EXACTLY happens when some, but not all, of the Infrastructure Masters are on Global Catalogs?

    - by MDMarra
    There are plenty of TechNet articles, like this one that say that phantom object don't get updated if an Infrastructure Master is also a Global Catalog, but other than that there isn't a lot of in depth information on what actually happens in this configuration. Imagine a configuration like this: |--------------| | example.com | | | | dedicated IM | |--------------| | | | |-------------------| | child.example.com | | | | IM on a GC | |-------------------| Where child has two DCs that are both global catalogs, meaning that the Infrastructure Master role is on a GC. And, example has three DCs with the Infrastructure Master role on a DC that is not a GC. I understand that it's usually best to just make everything a GC and not have to worry about this sort of thing, but assuming that's not the case - what is the exact error behavior that can be expected from a setup like this, and which domain(s) would this behavior manifest in? The child or the parent?

  • How do I apply WinHTTP proxy settings domain-wide?

    - by Oliver Salzburg
    We're already configuring Internet Explorer proxy settings through group policy and it works great. Sadly, I've recently run into multiple issues where those settings are ignored by certain services. I realized that these service have one thing in common. They use WinHTTP, which has its own proxy settings. Now I'm asking myself how to apply those across the whole domain. I realize that I could create a logon script and simply run netsh winhttp import proxy source=ie, but, from experience I know that these settings require a reboot to take effect. So this wouldn't help me at all in a logon script. So, how can I do it?
