• Intermediate SSL Certificates on Azure Websites

  - by amhed

  I have successfully configured an Extended-Validation Certificate on an Azure Website following this article: http://www.windowsazure.com/en-us/documentation/articles/web-sites-configure-ssl-certificate/ The main (non-technical) stakeholder of the web application went through great lengths to validate that our site is secure. He went to this site to check the validity of our SSL: http://www.whynopadlock.com/ The site throw the following error: `SSL verification issue (Possibly mis-matched URL or bad intermediate cert.). Details: ERROR: no certificate subject alternative name matches`` The certificate is installed using IP Based SSL instead of SNI. This is done this way because some site visitors still use Internet Explorer 8 on Windows XP, which has no support for SNI and throws a security warning. Is my certificate correclty installed? I received three .CRT files from my SSL provider: PrimaryIntermediate.crt SecondaryIntermediate.crt EndCertificate.crt This is how I exported our certificate as a .PFX file to Azure: openssl pkcs12 -export -out myserver.pfx -inkey myserver.key -in myserver.crt

• Why don't I just build the whole web app in Javascript and Javascript HTML Templates?

  - by viatropos

  I'm getting to the point on an app where I need to start caching things, and it got me thinking... In some parts of the app, I render table rows (jqGrid, slickgrid, etc.) or fancy div rows (like in the New Twitter) by grabbing pure JSON and running it through something like Mustache, jquery.tmpl, etc. In other parts of the app, I just render the info in pure HTML (server-side HAML templates), and if there's searching/paginating, I just go to a new URL and load a new HTML page. Now the problem is in caching and maintainability. On one hand I'm thinking, if everything was built using Javascript HTML Templates, then my app would serve just an HTML layout/shell, and a bunch of JSON. If you look at the Facebook and Twitter HTML source, that's basically what they're doing (95% json/javascript, 5% html). This would make it so my app only needed to cache JSON (pages, actions, and/or records). Which means you'd hit the cache no matter if you were some remote api developer accessing a JSON api, or the strait web app. That is, I don't need 2 caches, one for the JSON, one for the HTML. That seems like it'd cut my cache store down in half, and streamline things a little bit. On the other hand, I'm thinking, from what I've seen/experienced, generating static HTML server-side, and caching that, seems to be much better performance wise cross-browser; you get the graphics instantly and don't have to wait that split-second for javascript to render it. StackOverflow seems to do everything in plain HTML, and you can tell... everything appears at once. Notice how though on twitter.com, the page is blank for .5-1 seconds, and the page chunks in: the javascript has to render the json. The downside with this is that, for anything dynamic (like endless scrolling, or grids), I'd have to create javascript templates anyway... so now I have server-side HAML templates, client-side javascript templates, and a lot more to cache. My question is, is there any consensus on how to approach this? What are the benefits and drawbacks from your experience of mixing the two versus going 100% with one over the other? Update: Some reasons that factor into why I haven't yet made the decision to go with 100% javascript templating are: Performance. Haven't formally tested, but from what I've seen, raw html renders faster and more fluidly than javascript-generated html cross-browser. Plus, I'm not sure how mobile devices handle dynamic html performance-wise. Testing. I have a lot of integration tests that work well with static HTML, so switching to javascript-only would require 1) more focused pure-javascript testing (jasmine), and 2) integrating javascript into capybara integration tests. This is just a matter of time and work, but it's probably significant. Maintenance. Getting rid of HAML. I love HAML, it's so easy to write, it prints pretty HTML... It makes code clean, it makes maintenance easy. Going with javascript, there's nothing as concise. SEO. I know google handles the ajax /#!/path, but haven't grasped how this will affect other search engines and how older browsers handle it. Seems like it'd require a significant setup.

• Troubleshooting mailserver (Postfix, Dovecot) on Ubuntu Server 9.10?

  - by Christoffer

  I have configured a mail server with Postfix and Dovecot on Ubuntu Server 9.10. I followed the guidelines here (using Maildir): https://help.ubuntu.com/community/Postfix https://help.ubuntu.com/community/Dovecot The tests seemed alright so I connected it to GMail which is able to connect and fetch e-mails. But since there's no e-mail in the Maildir/ directory I can't decide if the problem is Postfix or Dovecot. And I am totally new to mailservers so I don't know where to start troubleshooting. So, I want to start by testing Dovecot. How can I create a fake "Hello World"-email directly on the server (using a text editor) so that I can try to fetch it with GMail? If Dovecot is alright, where do I start looking for errors in Postfix? Thank you for your time. Christoffer

• how can i use apache log files to recreate usage scenario

  - by daigorocub

  Recently i installed a website that had too many requests and it was too slow. Many improvements have been made to the web site code and we've also bought a new server. I want to test the new server with exactly the same requests that made the old server slow. After that, i will double the requests, make new tests and so on. These requests are logged in the apache log files. So, I can parse those files and make some kind of script to make the same requests. Of course, in this case, the requests will be made only by my computer against the server, but hey, better than nothing. Questions: - is there some app that does this already? - would you use wget? ab? python script? Thanks!

• Fluent Nhibernate - how do i specify table schemas when auto generating tables in SQL CE 4

  - by daffers

  I am using SQL CE as a database for running local and CI integration tests (normally our site runs on normal SQL server). We are using Fluent Nhibernate for our mapping and having it create our schema from our Mapclasses. There are only two classes with a one to many relationship between them. In our real database we use a non dbo schema. The code would not work with this real database at first until i added schema names to the Table() methods. However doing this broke the unit tests with the error... System.Data.SqlServerCe.SqlCeException : There was an error parsing the query. [ Token line number = 1,Token line offset = 26,Token in error = User ] These are the classes and associatad MapClasses (simplified of course) public class AffiliateApplicationRecord { public virtual int Id { get; private set; } public virtual string CompanyName { get; set; } public virtual UserRecord KeyContact { get; private set; } public AffiliateApplicationRecord() { DateReceived = DateTime.Now; } public virtual void AddKeyContact(UserRecord keyContactUser) { keyContactUser.Affilates.Add(this); KeyContact = keyContactUser; } } public class AffiliateApplicationRecordMap : ClassMap<AffiliateApplicationRecord> { public AffiliateApplicationRecordMap() { Schema("myschema"); Table("Partner"); Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.CompanyName, "Name"); References(x => x.KeyContact) .Cascade.All() .LazyLoad(Laziness.False) .Column("UserID"); } } public class UserRecord { public UserRecord() { Affilates = new List<AffiliateApplicationRecord>(); } public virtual int Id { get; private set; } public virtual string Forename { get; set; } public virtual IList<AffiliateApplicationRecord> Affilates { get; set; } } public class UserRecordMap : ClassMap<UserRecord> { public UserRecordMap() { Schema("myschema"); Table("[User]");//Square brackets required as user is a reserved word Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.Forename); HasMany(x => x.Affilates); } } And here is the fluent configuraton i am using .... public static ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database( MsSqlCeConfiguration.Standard .Dialect<MsSqlCe40Dialect>() .ConnectionString(ConnectionString) .DefaultSchema("myschema")) .Mappings(m => m.FluentMappings.AddFromAssembly(typeof(AffiliateApplicationRecord).Assembly)) .ExposeConfiguration(config => new SchemaExport(config).Create(false, true)) .ExposeConfiguration(x => x.SetProperty("connection.release_mode", "on_close")) //This is included to deal with a SQLCE issue http://stackoverflow.com/questions/2361730/assertionfailure-null-identifier-fluentnh-sqlserverce .BuildSessionFactory(); } The documentation on this aspect of fluent is pretty weak so any help would be appreciated

• Obsessive behaviors in sysadmins

  - by squillman

  I have been told by colleagues (mainly non-technical) that some of my admin behaviors border on / cross the line between normal and obsessive, which sometimes leads me to wonder how screwed up I really am (read "how screwed up everyone else really is"). What are your obsessive behaviors when it comes to your sysadmin tasks and job functions? What do you do religiously that would make you twitch if you didn't do it or that others just roll their eyes at? I have reasons for my actions. I want to prove to my coworkers that I'm not alone.

• Login sometimes failing immediately after restoring a database

  - by Ian Ringrose

  We have a set of automated tests that restore a database then run some .net code against the database. Sometimes after the database is restored the login from Ado.net fails. If I re-run the test, then the restore and login works OK. The restored database looks OK when viewed with Management Studio. This is only an problem on some machines. We are using SQL server 2008. Is there a known issue with a database restore “returning “ a very short time before the restored database is up and running.

• Can't serve files without extension because they "appear to be script" on IIS7.5

  - by madd0

  I created a certain number of static JSON files with no extension in a subfolder of my site. I want to use them for tests. The problem is that IIS is refusing to serve them because : HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. The folder is a subfolder of an ASP.NET application and I can't create an application just for it, neither can I change the parent application's application pool. Actually, I don't have access to the IIS configuration other than through the web.config file in the folder in question. I assume there must be a way to get a web server to serve static files, right?

• maven test cannot load cross-module resources/properties ?

  - by smallufo

  I have a maven mantained project with some modules . One module contains one XML file and one parsing class. Second module depends on the first module. There is a class that calls the parsing class in the first module , but maven seems cannot test the class in the second module. Maven test reports : java.lang.NullPointerException at java.util.Properties.loadFromXML(Properties.java:851) at foo.firstModule.Parser.<init>(Parser.java:92) at foo.secondModule.Program.<init>(Program.java:84) In "Parser.java" (in the first module) , it uses Properties and InputStream to read/parse an XML file : InputStream xmlStream = getClass().getResourceAsStream("Data.xml"); Properties properties = new Properties(); properties.loadFromXML(xmlStream); The "data.xml" is located in first module's resources/foo/firstModule directory , and it tests OK in the first module. It seems when testing the second module , maven cannot correctly load the Data.xml in the first module . I thought I can solve the problem by using maven-dependency-plugin:unpack to solve it . In the second module's POM file , I add these snippets : <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.1</version> <executions> <execution> <id>data-copying</id> <phase>test-compile</phase> <goals> <goal>unpack</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>foo</groupId> <artifactId>firstModule</artifactId> <type>jar</type> <includes>foo/firstModule/Data.xml</includes> <outputDirectory>${project.build.directory}/classes</outputDirectory> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin> In this POM file , I try to unpack the first module , and copy the Data.xml to classes/foo/firstModule/ directory , and then run tests. And indeed , it is copied to the right directory , I can find the "Data.xml" file in "target/classes/foo/firstModule" directory. But maven test still complains it cannot read the File (Properties.loadFromXML() throws NPE). I don't know how to solve this problem. I tried other output directory , such as ${project.build.directory}/resources , and ${project.build.directory}/test-classes , but all in vain... Any advices now ? Thanks in advanced. Environments : Maven 2.2.1 , eclipse , m2eclipse

• Trigger ZFS dedup one-off scan/rededup

  - by Jake Wharton

  I have a ZFS filesystems which has been running for some time and I recently had the opportunity to upgrade it (finally!) to the latest ZFS version. Our data doesn't scream dedup but I firmly believe based on small tests that we could gain anywhere from 5-10% of our space back for free by utilizing it. I have enabled dedup on the filesystem and new files are slowly being dedupified but the majority (95%+) of our data already exists on the filesystem. Short of moving the data off-pool and then recopying it back, is there any way to trigger a dedup scan of existing data? It doesn't have to be asynchronous or live. (And FYI there isn't enough room on the pool to copy the entire filesystem to another and then just switch the mounts.)

• How to make the jump from consumer support to enterprise support?

  - by Zac Cramer

  I am currently a high level consumer break/fix technician responsible for about 300-400 repairs a month. I am good at my job, but bored, and I want to move into the enterprise side of my company, dealing with Server 2008 R2 and exchange and switches and routers that cost more than I make in a month. How do I make this transition? Whats the best thing to learn first? Is there a standard trajectory for making this leap from consumer to business? I am full time employed, so going back to school is not a great option, but I have no life, so spending my nights and weekends reading and practicing is totally within my realm. I am basically overwhelmed by the number of things to learn, and looking for any advice you may have on the best way to proceed. PS - I apologize if this is a not quite the right forum for this, I know its not a technical question exactly, but I also know the sorts of people I want to answer this question are reading this website.

• Using Apache Environment Variables to set custom ErrorDocument

  - by Tad

  I've got a set of RewriteCond rules that test for various mobile devices and then set environment variables like "env=device:.iphone" or "env=device:.smartphone" if the useragent matches an iPhone or Android device. I'm trying to now redirect the user to custom-styled 404/500 server error pages for each device, by way of the error pages. Ideally I'd like to be able to test for a variable being there, and then write in a custom ErrorDocument string. But an apache doesn't seem to work in this case. Any ideas how I can construct if/else tests in an apache conf file for environment vars?

• What has changed to make it possible to develop USB3.0

  - by RoboShop

  Like I know the transfer speeds are vastly different. But I don't understand is why they are faster. And why couldn't they have implemented USB 3.0 when they released 1.0? Like what technical breakthrough was required to get transfer speeds that fast? Was it cost? capacities of computer? like they couldn't read the data fast enough? Although USB is still well below hard drive transfer speeds engineering breakthrough? They found some new material which could transfer at a faster rate? Was this in the cable itself? In the hardware?

• Explorer hijacked by a trojan

  - by hsdb

  I managed to catch a newish trojan that my Anti virus program wasn't able to detect. I'm usually not that bad at technical stuff regarding computers but I really don't know what to do with this one anymore. The trojan somehow managed to get my Windows to recover it every time I try to remove it by deleting it's exe (called some weird name located in Programs "asdza/saddasn.exe" (example only)). It also sets an entry in my autostart. It starts a second explorer.exe and tries to connect to some server obviously trying to steal data. (glad I still have my firewall) How can I get rid of this trojan, I really need help. It is new and probably unrecognized by all major virus scanners.

• How do I negotiate for colo space?

  - by randy melder

  I guess this isn't a technical question, but it definitely is something IT teams deal with, so here goes: I'm looking at getting a rack at a local colocation facility. I'm weighing the options versus building out in a cloud platform. We are REALLY low bandwidth and power. There's a total of six hosts for the total operation. You can assume we use <= 10 amps of power and <= 2Mbps 95th percentile. Do you have any advice for getting the best deal?

• Vetting Github Pull requests with Hudson

  - by cdecker

  I've been using Gerrit and Hudson very successfully to test and automatically vote on new checkins in the past and now I'm wondering whether it is possible to set up Hudson so that it'll check Github at regular intervals and looks if there are new Pull Requests available. If yes it should apply the patch and run the unit tests against it, adding a comment to the pull request if no failure is detected. It would certainly reduce the amount of work going into vetting patches/pull requests. Is that possible at all, or should I stick with my Gerrit setup?

Thank you!

• Overloading '-' for array subtraction

  - by Chris Wilson

  I am attempting to subtract two int arrays, stored as class members, using an overloaded - operator, but I'm getting some peculiar output when I run tests. The overload definition is Number& Number :: operator-(const Number& NumberObject) { for (int count = 0; count < NumberSize; count ++) { Value[count] -= NumberObject.Value[count]; } return *this; } Whenever I run tests on this, NumberObject.Value[count] always seems to be returning a zero value. Can anyone see where I'm going wrong with this? The line in main() where this subtraction is being carried out is cout << "The difference is: " << ArrayOfNumbers[0] - ArrayOfNumbers[1] << endl; ArrayOfNumbers contains two Number objects. The class declaration is #include <iostream> using namespace std; class Number { private: int Value[50]; int NumberSize; public: Number(); // Default constructor Number(const Number&); // Copy constructor Number(int, int); // Non-default constructor void SetMemberValues(int, int); // Manually set member values int GetNumberSize() const; // Return NumberSize member int GetValue() const; // Return Value[] member Number& operator-=(const Number&); }; inline Number operator-(Number Lhs, const Number& Rhs); ostream& operator<<(ostream&, const Number&); The full class definition is as follows: #include <iostream> #include "../headers/number.h" using namespace std; // Default constructor Number :: Number() {} // Copy constructor Number :: Number(const Number& NumberObject) { int Temp[NumberSize]; NumberSize = NumberObject.GetNumberSize(); for (int count = 0; count < NumberObject.GetNumberSize(); count ++) { Temp[count] = Value[count] - NumberObject.GetValue(); } } // Manually set member values void Number :: SetMemberValues(int NewNumberValue, int NewNumberSize) { NumberSize = NewNumberSize; for (int count = NewNumberSize - 1; count >= 0; count --) { Value[count] = NewNumberValue % 10; NewNumberValue = NewNumberValue / 10; } } // Non-default constructor Number :: Number(int NumberValue, int NewNumberSize) { NumberSize = NewNumberSize; for (int count = NewNumberSize - 1; count >= 0; count --) { Value[count] = NumberValue % 10; NumberValue = NumberValue / 10; } } // Return the NumberSize member int Number :: GetNumberSize() const { return NumberSize; } // Return the Value[] member int Number :: GetValue() const { int ResultSoFar; for (int count2 = 0; count2 < NumberSize; count2 ++) { ResultSoFar = ResultSoFar * 10 + Value[count2]; } return ResultSoFar; } Number& operator-=(const Number& Rhs) { for (int count = 0; count < NumberSize; count ++) { Value[count] -= Rhs.Value[count]; } return *this; } inline Number operator-(Number Lhs, const Number& Rhs) { Lhs -= Rhs; return Lhs; } // Overloaded output operator ostream& operator<<(ostream& OutputStream, const Number& NumberObject) { OutputStream << NumberObject.GetValue(); return OutputStream; }

• Methodologies for performance-testing a WAN link

  - by Chopper3

  We have a pair of new diversely-routed 1Gbps Ethernet links between locations about 200 miles apart. The 'client' is a new reasonably-powerful machine (HP DL380 G6, dual E56xx Xeons, 48GB DDR3, R1 pair of 300GB 10krpm SAS disks, W2K8R2-x64) and the 'server' is a decent enough machine too (HP BL460c G6, dual E55xx Xeons, 72GB, R1 pair of 146GB 10krpm SAS disks, dual-port Emulex 4Gbps FC HBA linked to dual Cisco MDS9509s then onto dedicated HP EVA 8400 with 128 x 450GB 15krpm FC disks, RHEL 5.3-x64). Using SFTP from the client we're only seeing about 40Kbps of throughput using large (2GB) files. We've performed server to 'other local server' tests and see around 500Mbps through the local switches (Cat 6509s), we're going to do the same on the client side but that's a day or so away. What other testing methods would you use to prove to the link providers that the problem is theirs?

• Update saved password for basic authentication using a script

  - by Kalamane

  I have a website that uses basic authentication as described on this webpage. Each of the computers I manage have the password saved in their browser. There is only one username and password for this. After someone logs in to the site this way, they are presented with their individual username and password prompt as part of the web page. The purpose of the initial username/password is to discourage non-technical employees that aren't supposed to be using the page from even viewing it. So far, when we've had to change this password, I've manually gone to each computer and updated the saved password. I'm writing a startup script to configure other aspects of these systems so that I can maintain them easier. I'd like to be able to update the saved password via this script. The operating system running on these machines is Windows XP SP3 and the browsers they're using to access this site are IE8 and IE9. How can I update the saved basic authentication information for a website via a script?

• How realistic/easy is it to host our own web servers?

  - by morpheous

  It is increasingly looking like we will need to host our own servers, because we need modems physically attached to the server machines. I (think) we will need a T1 line to our office for starters. Dont know what else is involved other than the obvious redundancy and failover requirements. My questions are: Do we really have to do it our selves or can we find a service that allows the modems to be remote as well? If we have to host the servers ourselves, what are the steps (technical and operational) required?

• OS X Login Authentication Against Leopard Server

  - by mattdwen

  I am doing a few tests with OS X Server before I have to do a deploy in a few months. I have configured Open Directory, and created a few users. I've configured Directory Utility on a 10.5 client, but the login authentication doesn't work the way I would expect. I would expect I could user a username/password from any user created in Open Directory and be able to log into the client. Instead, it appears I need to create a local user, which you then sync with a directory user using Directory Utility. Alternatively, if I add an Active Directory config to the client, I can use any AD user, as I would expect. Am I hoping for the impossible, or is something likely wrong with the configuration?

• Huge HDD response time in Resource monitor

  Just bought all parts for a computer and put it together and installed a fresh version of windows 7. After a while, when using the computer it gets very slow, and even closing down windows can take several minutes. I started to look in the resource monitor and though I found the answer watching my hdd. The thing is that the hdd completes all tests in Seagate's SeaTools for Windows successfully. Which makes me doubt on the problem and weather I can send it in to get an replacement. Suggestions on what it could be and what I can do about it? Here a screenshoot from the resource monitor:

• Refactoring a leaf class to a base class, and keeping it also a interface implementation

  - by elcuco

  I am trying to refactor a working code. The code basically derives an interface class into a working implementation, and I want to use this implementation outside the original project as a standalone class. However, I do not want to create a fork, and I want the original project to be able to take out their implementation, and use mine. The problem is that the hierarchy structure is very different and I am not sure if this would work. I also cannot use the original base class in my project, since in reality it's quite entangled in the project (too many classes, includes) and I need to take care of only a subdomain of the problems the original project is. I wrote this code to test an idea how to implement this, and while it's working, I am not sure I like it: #include <iostream> // Original code is: // IBase -> Derived1 // I need to refactor Derive2 to be both indipendet class // and programmers should also be able to use the interface class // Derived2 -> MyClass + IBase // MyClass class IBase { public: virtual void printMsg() = 0; }; /////////////////////////////////////////////////// class Derived1 : public IBase { public: virtual void printMsg(){ std::cout << "Hello from Derived 1" << std::endl; } }; ////////////////////////////////////////////////// class MyClass { public: virtual void printMsg(){ std::cout << "Hello from MyClass" << std::endl; } }; class Derived2: public IBase, public MyClass{ virtual void printMsg(){ MyClass::printMsg(); } }; class Derived3: public MyClass, public IBase{ virtual void printMsg(){ MyClass::printMsg(); } }; int main() { IBase *o1 = new Derived1(); IBase *o2 = new Derived2(); IBase *o3 = new Derived3(); MyClass *o4 = new MyClass(); o1->printMsg(); o2->printMsg(); o3->printMsg(); o4->printMsg(); return 0; } The output is working as expected (tested using gcc and clang, 2 different C++ implementations so I think I am safe here): [elcuco@pinky ~/src/googlecode/qtedit4/tools/qtsourceview/qate/tests] ./test1 Hello from Derived 1 Hello from MyClass Hello from MyClass Hello from MyClass [elcuco@pinky ~/src/googlecode/qtedit4/tools/qtsourceview/qate/tests] ./test1.clang Hello from Derived 1 Hello from MyClass Hello from MyClass Hello from MyClass The question is My original code was: class Derived3: public MyClass, public IBase{ virtual void IBase::printMsg(){ MyClass::printMsg(); } }; Which is what I want to express, but this does not compile. I must admit I do not fully understand why this code work, as I expect that the new method Derived3::printMsg() will be an implementation of MyClass::printMsg() and not IBase::printMsg() (even tough this is what I do want). How does the compiler chooses which method to re-implement, when two "sister classes" have the same virtual function name? If anyone has a better way of implementing this, I would like to know as well :)
