  • IT Admin for Thrill Seekers

    - by Tony Davis
    A developer suggested to me recently that the life of the DBA was, surely, a dull one. My first reaction was indignation, but quickly followed by the thought that for many people excitement isn't necessarily the most desirable aspect of their job. It's true that some aspects of the DBA role seem guaranteed to quieten the pulse; in the days of tape backups, time must have slowed to eternity for the person whose job it was to oversee this process, placing tapes into secure containers, ensuring correct labeling, and.sorry, I drifted off there for a second. On the other hand, if you follow the adventures of the likes of Brent Ozar or Tom LaRock, you'd be forgiven for thinking that much of a database guy's time is spent, metaphorically, diving through plate glass windows in tight fitting underwear in order to extract grateful occupants from burning database applications. Alas it isn't true of the majority, but it isn't as dull as some people imagine, and is a helter-skelter ride compared with some other IT roles. Every IT department has people who toil away in shadowy corners doing quiet but mysterious tasks. When you ask them to explain what they do, you almost immediately want them to stop, but you hear enough to appreciate that these tasks are often absolutely vital to the smooth functioning of an IT organization. Compared with them, the DBAs are prima donnas. Here are a few nominations: Installation engineer - install all of the company's laptops and workstations, and software, deal with licensing, shipping and data entry.many organizations, especially those subject to tight regulation, would simply grind to a halt without their efforts. Localization engineer - Not quite software engineering, not quite translation, the job is to rebuild a product in a different language and make sure everything still works. QA Tester - firstly, I should say that the testers at Red Gate seem to me some of the most-fulfilled in the company. I refer here to the QA Tester whose job is more-or-less entirely to read a script, click some buttons and make sure the actual and expected values match. Configuration manager - for example, someone whose main job is to configure build environments so that devs can access their source code; assuredly necessary for the smooth functioning and productivity of the team, and hopefully well-paid. So what other sort of job in IT should one choose if the work of a DBA proves to be too exciting? Or are these roles secretly more exciting than many imagine? I invite you all to put forward your own suggestions. Cheers, Tony.

  • Meet Peter, 80 years old today

    - by AdamRG
    You have to arrive at the office early in the morning to meet Peter. He arrives at 5am and by 8:30am he's gone. Peter has been a cleaner here for several years. He is 80 years old today. Peter was born only a couple of km from our office in Cambridge, England and was for many years an Engineer for Pye Electronics. I'm lucky enough to arrive in the office early enough to catch Peter, dressed smarter than most of us in shirt and tie, and he tells stories of how Cambridge was years ago. He says the site of our office is on land between what would have been a prisoner of war camp (camp 1025), and a few hundred metres North, a camp of American allies. In February 1944, Peter was 13 years old. One night, a Dornier Do 217 heavy bomber heading towards London was hit by anti-aircraft fire and the crew of four parachuted from the plane. The plane however, continued on autopilot for over 50km. Gradually dropping lower and lower, narrowly missing the spires of Cambridge, it eventually came to land, largely intact, in allotment gardens by Peter's house near Milton Road. He told me that he was quick to the scene, along with some other young lads, and grabbed parts of the plane as souvenirs. It's one of many tales that Peter recounts, but I happened to discover a chapter about this particular plane crash in a history book called the War Torn Skies of Great Britain by Julian Evan-Hart. It reads: 'It slid to a halt in the allotment gardens of Milton Road. The cockpit ended up crumpled against a wooden fence and several incendiary bombs that had broken loose from their containers in the ruptured bomb bay were strewn over the ground behind the Dornier.' I smiled when I read the following line: 'Many residents came to see the Dornier in the allotments. Several lads made off with souvenirs' It seems a young Peter has been captured in print! For his birthday, among other things, we gave him a copy of the book. Working for a software company and rushing headlong through the 21st century, it's easy to forget even our recent history, or what feet stood on the same ground before us. That aircraft crashed only 700 metres from where our office now stands. The disused and overgrown railway line that runs down the side of the office closed to passengers 30 years ago. The industrial estate the other side was the site of a farm, Trinity Hall Farm, as recently as 60 years ago. Roman rings and Palaeolithic handaxes have been unearthed nearby. I suppose Peter will be one of the last people I'll ever hear talking first-hand about Cambridge during the war. It's a privilege to know him. Happy birthday Peter.

  • debootstrap or virt-install Ubuntu Server Maverick fails

    - by poelinca
    Oki so running any kind of variation of debootsrap i get the following error I: Extracting zlib1g... W: Failure trying to run: chroot /lxc/iso/dodo mount -t proc proc /proc debootstrap.log : mount: permission denied if i manualy chroot into the directory then i get promted with: id: cannot find name for group ID 0 I have no name!@...# i tryed addgroup but it's not installed , apt-get/aptitude : command not found , so i can't do anything with it . I've tryed ubuntu-vm-builder but since it's calling debootstrap i get the same error . Played with it for a few days and then i stoped and gaved virt-install a try , everithing works till i get to the console to finish the install witch shows only : Escape character is ^] and nothing more , no matter what i type . So basicly what i'm trying to do is build a usable chroot system so i can use it with lxc or libvirt . What are my options to get containers/virtualisation up and running ? I've read somewhere that i can use openvz templates with lxc or libvirt ? but how ? Let me know if you need aditional info ( p.s. doing all this on a dedicated server so i can't access it by hand , only ssh , plus on my local pc running ubuntu desktop maverick everithing works ) . EDIT Getting closer , i managed to understand how to use an openvz template with lxc , now the problem comes with the network bridge lxc-start: invalid interface name: br0 # Use same bridge device used in your controlling host setup lxc-start: failed to process 'lxc.network.link = br0 # Use same bridge device used in your controlling host setup ' lxc-start: failed to read configuration file i followed the exact steps to create a bridge and lxc conf looks like: lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 # Use same bridge device used in your controlling host setup lxc.network.hwaddr = {a1:b2:c3:d4:e5:f6} # As appropiate (line only needed if you wish to dhcp later) lxc.network.ipv4 = {10.0.0.100} # (Use 0.0.0.0 if you wish to dhcp later) lxc.network.name = eth0 # could likely be whatever you want Since it's not working i know smth is wrong so could somebody guyde me ? EDIT , looks like the base install was using an custom kernel ( bzImage-2.6.34.6-xxxx-grs-ipv6-65 ) for witch you i didn't found the headers , i did a update-grub after i installed a new kernel , edited menu.lst and no it's using 2.6.35-23-server and now debootstrap is working just fine same as ubuntu-vm-builder .

  • What to do if I am working on a language that I don't like

    - by Sayem Ahmed
    Hi there, I really don't know if this is the right place to ask this question, but if it isn't, then I guess someone will notify. Anyway, I am working in a software development farm which is currently using PowerBuilder to develop a mid-size ERP solution. The work environment and company management are so great that it may be the best in the whole Bangladesh. Only problem is the technology that are currently being used, which is this PowerBuilder. Now I am a guy who tends to prefer modern development technologies, like DI containers, ORM, TDD, JQuery etc. PowerBuilder is a great tool too, but I couldn' like the application techniques used to build PB applications. These techniques are so inheritance-dependent that many a times these create a great deal of sufferings. I remember two days ago I had to change some processing logic in a core user object and as a result I had to test and re-test all the forms that the application have(apparently, there are almost 20 forms there, each of them with 3-4 kinds of functionalities). Also, learning PB is tough, because online material on this thing is very, very low. I can't afford to read all the documentation that PB provide because I have hard deadlines on the work that I have to do. Another thing with PB is that applications tend to rely on business logic that are implemented on databases which causes debugging to be a nightmare. As a result, I don't feel motivated enough to work in this IDE/System/Framework (or whatever) anymore. My productivity has greatly decreased, and I am not delivering quality code. I think I have the following options available to me - Remain in the current job, keep delivering worse code and let my productivity decrease day by day, taking salaries and bonuses but not delivering quality codes/doing my job the way I should, Search for a new job. At this point number 2 seems a good option, but there are also some issues. As I mentioned before, our management may be the best in the country. Our company owner is himself a software developer with 24 years of experience in software development. He is currently our Team Leader and System Analyst. He is by far the greatest manager and boss I have ever seen. He understands developer's mentality very well(as he IS himself a developer). He is also a great, kind and generous guy. Our company is only a start-up company with 10 developers. Among them, only 3-4 people knows about the business logic behind the ERP, and I am one of them. If I switch my current job, it may hamper the development of this product which I really don't want. I couldn't decide what to do in this situation, so I turned to the community for advice.

  • const vs. readonly for a singleton

    - by GlenH7
    First off, I understand there are folk who oppose the use of singletons. I think it's an appropriate use in this case as it's constant state information, but I'm open to differing opinions / solutions. (See The singleton pattern and When should the singleton pattern not be used?) Second, for a broader audience: C++/CLI has a similar keyword to readonly with initonly, so this isn't strictly a C# type question. (Literal field versus constant variable in C++/CLI) Sidenote: A discussion of some of the nuances on using const or readonly. My Question: I have a singleton that anchors together some different data structures. Part of what I expose through that singleton are some lists and other objects, which represent the necessary keys or columns in order to connect the linked data structures. I doubt that anyone would try to change these objects through a different module, but I want to explicitly protect them from that risk. So I'm currently using a "readonly" modifier on those objects*. I'm using readonly instead of const with the lists as I read that using const will embed those items in the referencing assemblies and will therefore trigger a rebuild of those referencing assemblies if / when the list(s) is/are modified. This seems like a tighter coupling than I would want between the modules, but I wonder if I'm obsessing over a moot point. (This is question #2 below) The alternative I see to using "readonly" is to make the variables private and then wrap them with a public get. I'm struggling to see the advantage of this approach as it seems like wrapper code that doesn't provide much additional benefit. (This is question #1 below) It's highly unlikely that we'll change the contents or format of the lists - they're a compilation of things to avoid using magic strings all over the place. Unfortunately, not all the code has converted over to using this singleton's presentation of those strings. Likewise, I don't know that we'd change the containers / classes for the lists. So while I normally argue for the encapsulations advantages a get wrapper provides, I'm just not feeling it in this case. A representative sample of my singleton public sealed class mySingl { private static volatile mySingl sngl; private static object lockObject = new Object(); public readonly Dictionary<string, string> myDict = new Dictionary<string, string>() { {"I", "index"}, {"D", "display"}, }; public enum parms { ABC = 10, DEF = 20, FGH = 30 }; public readonly List<parms> specParms = new List<parms>() { parms.ABC, parms.FGH }; public static mySingl Instance { get { if(sngl == null) { lock(lockObject) { if(sngl == null) sngl = new mySingl(); } } return sngl; } } private mySingl() { doSomething(); } } Questions: Am I taking the most reasonable approach in this case? Should I be worrying about const vs. readonly? is there a better way of providing this information?

  • How to refactor a Python “god class”?

    - by Zearin
    Problem I’m working on a Python project whose main class is a bit “God Object”. There are so friggin’ many attributes and methods! I want to refactor the class. So Far… For the first step, I want to do something relatively simple; but when I tried the most straightforward approach, it broke some tests and existing examples. Basically, the class has a loooong list of attributes—but I can clearly look over them and think, “These 5 attributes are related…These 8 are also related…and then there’s the rest.” getattr I basically just wanted to group the related attributes into a dict-like helper class. I had a feeling __getattr__ would be ideal for the job. So I moved the attributes to a separate class, and, sure enough, __getattr__ worked its magic perfectly well… At first. But then I tried running one of the examples. The example subclass tries to set one of these attributes directly (at the class level). But since the attribute was no longer “physically located” in the parent class, I got an error saying that the attribute did not exist. @property I then read up about the @property decorator. But then I also read that it creates problems for subclasses that want to do self.x = blah when x is a property of the parent class. Desired Have all client code continue to work using self.whatever, even if the parent’s whatever property is not “physically located” in the class (or instance) itself. Group related attributes into dict-like containers. Reduce the extreme noisiness of the code in the main class. For example, I don’t simply want to change this: larry = 2 curly = 'abcd' moe = self.doh() Into this: larry = something_else('larry') curly = something_else('curly') moe = yet_another_thing.moe() …because that’s still noisy. Although that successfully makes a simply attribute into something that can manage the data, the original had 3 variables and the tweaked version still has 3 variables. However, I would be fine with something like this: stooges = Stooges() And if a lookup for self.larry fails, something would check stooges and see if larry is there. (But it must also work if a subclass tries to do larry = 'blah' at the class level.) Summary Want to replace related groups of attributes in a parent class with a single attribute that stores all the data elsewhere Want to work with existing client code that uses (e.g.) larry = 'blah' at the class level Want to continue to allow subclasses to extend, override, and modify these refactored attributes without knowing anything has changed Is this possible? Or am I barking up the wrong tree?

  • How To Build An Enterprise Application - Introduction

    - by Tuan Nguyen
    An enterprise application is a software which fulfills 4 core quality attributes: Reliability Flexibility Reusability Maintainability Reliability is the ability of a system or component to perform its required functions under stated conditions for a specific period of time. Because there are no ways more than testing to make sure a system is reliability, we can exchange the term reliability with the term testability. Flexibility is the ability of changing a system's core features without violating unrelated features or components. Although flexibility can helps us to achieve interoperability easily but the opposite is not true. For example, a program might run on multiple platforms, contains logic for many scenarios but that wouldn't mean it was flexibility if it forces us rewrite code in all components when we just want to change some aspects of a feature it had. Reusability is the ability of sharing one or more system's components for another system. We should just open a component's reusability in the context in which it is used. For example, we write classes that implement UI logic and deliver them to only classes which implementing UI. Maintainability is the ability of adding or removing features to a system after it was released. Maintainability consists of many factors such as readability, analyzability, extensibility therein extensibility is critical. Maintainability requires us to write code that is longer and complexer than normal but it doesn't mean we introduce unneccessarily complex code. We always try to make our code clear and transparent to everyone. An application enterprise is built on an enterprise design which consists of two parts: low-level design and high-level design. At low-level design, it focuses on building loose-coupled classes or components. Particularly, it recommends: Each class or component undertakes only single responsibility (design based on unit test) Classes or components implement and work through interfaces (design based on contract) Dependency relationship between classes and components could be injected at run-time (design based on dependency) At high-level design, it focuses on architecting system into tiers and layers. Particularly, it recommends: Divide system into subsystems for deployment. Each subsytem is called a tier. Typical, an enterprise application would have 3 tiers as illustrated in the following figure: Arrange classes and components to logical containers called layers. Typical, an enterprise application would have 5 layers as illustrated in the following figure

  • SQL SERVER – How to easily work with Database Diagrams

    - by Pinal Dave
    Databases are very widely used in the modern world. Regardless of the complexity of a database, each one requires in depth designing. To practice along please Download dbForge Studio now.  The right methodology of designing a database is based on the foundations of data normalization, according to which we should first define database’s key elements – entities. Afterwards the attributes of entities and relations between them are determined. There is a strong opinion that the process of database designing should start with a pencil and a blank sheet of paper. This might look old-fashioned nowadays, because SQL Server provides a much wider functionality for designing databases – Database Diagrams. When using SSMS for working with Database Diagrams I realized two things – on the one hand, visualization of a scheme allows designing a database more efficiently; on the other – when it came to creating a big scheme, some difficulties occurred when designing with SSMS. The alternatives haven’t taken long to wait and dbForge Studio for SQL Server is one of them. Its functions offer more advantages for working with Database Diagrams. For example, unlike SSMS, dbForge Studio supports an opportunity to drag-and-drop several tables at once from the Database Explorer. This is my opinion but personally I find this option very useful. Another great thing is that a diagram can be saved as both a graphic file and a special XML file, which in case of identical environment can be easily opened on the other server for continuing the work. During working with dbForge Studio it turned out that it offers a wide set of elements to operate with on the diagram. Noteworthy among such elements are containers which allow aggregating diagram objects into thematic groups. Moreover, you can even place an image directly on the diagram if the scheme design is based on a standard template. Each of the development environments has a different approach to storing a diagram (for example, SSMS stores them on a server-side, whereas dbForge Studio – in a local file). I haven’t found yet an ability to convert existing diagrams from SSMS to dbForge Studio. However I hope Devart developers will implement this feature in one of the following releases. All in all, editing Database Diagrams through dbForge Studio was a nice experience and allowed speeding-up the common database designing tasks. Download dbForge Studio now.

  • How can I solve the same problems a CB-architecture is trying to solve without using hacks? [on hold]

    - by Jefffrey
    A component based system's goal is to solve the problems that derives from inheritance: for example the fact that some parts of the code (that are called components) are reused by very different classes that, hypothetically, would lie in a very different branch of the inheritance tree. That's a very nice concept, but I've found out that CBS is often hard to accomplish without using ugly hacks. Implementations of this system are often far from clean. But I don't want to discuss this any further. My question is: how can I solve the same problems a CBS try to solve with a very clean interface? (possibly with examples, there are a lot of abstract talks about the "perfect" design already). Here's an example I was going for before realizing I was just reinventing inheritance again: class Human { public: Position position; Movement movement; Sprite sprite; // other human specific components }; class Zombie { Position position; Movement movement; Sprite sprite; // other zombie specific components }; After writing that I realized I needed an interface, otherwise I would have needed N containers for N different types of objects (or to use boost::variant to gather them all together). So I've thought of polymorphism (move what systems do in a CBS design into class specific functions): class Entity { public: virtual void on_event(Event) {} // not pure virtual on purpose virtual void on_update(World) {} virtual void on_draw(Window) {} }; class Human { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; class Zombie { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; Which was nice, except for the fact that now the outside world would not even be able to know where a Human is positioned (it does not have access to its position member). That would be useful to track the player position for collision detection or if on_update the Zombie would want to track down its nearest human to move towards him. So I added const Position& get_position() const; to both the Zombie and Human classes. And then I realized that both functionality were shared, so it should have gone to the common base class: Entity. Do you notice anything? Yes, with that methodology I would have a god Entity class full of common functionality (which is the thing I was trying to avoid in the first place).

  • Exchange 2010, Exchange 2003 Mail Flow issue

    - by Ryan Roussel
    While performing the initial Exchange 2010 deployment for a customer migrating from Exchange 2003, I ran into an issue with mail flow between the two environments.  The Exchange 2003 mailboxes could send to Exchange 2010, as well as to and from the internet.  Exchange 2010 mailboxes could send and receive to the internet, however they could not send to Exchange 2003 mailboxes.   After scouring the internet for a solution, it seemed quite a few people were experiencing this issue with no resolution to be found, or at least not easily.  After many attempts of manually deleting and recreating the routing group connectors,  I finally lucked onto the answer in an obscure comment left to another blogger.   If inheritable permissions are not allowed on the Exchange 2003 object in the Active Directory schema, exchange server authentication cannot be achieved between the servers.   It seems when Blackberry Enterprise Server gets added to 2003 environments, a lot of Admins get tricky and add the BES Admin user explicitly to the server object  to allow  inheritance down from there to all mailboxes.  The problem is they also coincidently turn off inheritance to the server object itself from its parent containers.  You can re-establish inheritance without overwriting the existing ACL however so that the BES Admin can remain in the server object ACL.   By re-establishing inheritance to the 2003 server object, mail flow was instantly restored between the servers.    To re-establish inheritance: 1. Open ASDIedit by adding the snap-in to a MMC (should be included on your 2008 server where Exchange 2010 is installed) 2. Navigate to Configuration > Services > Microsoft Exchange > Exchange Organization > Administrative Groups > First Administrative Group > Servers 3. In the right pane, right click on the CN=Server Name of your Exchange 2003 Server, select properties 4. Navigate to the Security tab, hit advanced toward the bottom. 5. Check the checkbox that reads “include inheritable permissions” toward the bottom of the dialogue box.

For this, specify the id property value of the component that you want to put the initial focus on. Identifiers are relative to the component, and must account for NamingContainers. You can use a single colon to start the search from the root, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container and begin the search from there, ":::" will pop out of two naming containers and begin the search from there. Alternatively you can add the naming container IDs as a prefix to the component Id, e.g. nc1:nc2:comp1. http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_document.html To set the initial focus to a component located in a page fragment that is exposed through an ADF region, keep in mind that ADF Faces regions - af:region - is a naming container too. To address an input text field with the id "it1" in an ADF region exposed by an af:region tag with the id r1, you use the following reference in af:document: <af:document id="d1" initialFocusId="r1:0:it1"> Note the "0" index in the client Id. Also, make sure the input text component has its clientComponent property set to true as otherwise no client component exist to put focus on.

  • map subdomain to another subdomain via cname

    - by Stephen
    Question: I need to get DNS configured to point a subdomain from one domain (which I will generally not be controlling) to another subdomain on a different domain name. Testing this process using a simple CNAME entry keeps pointing to the primary domain and not the subdomain where it should be going. This is the scenario; (newdomain.com is in my control) cdn.xyz.com should display content from this subdomain subdomain.newdomain.com It is instead displaying content from newdomain.com (not the subdomain sub domain) cdn.xyz.com/page.htm displays content from newdomain.com/page.htm although what I need is it to display content from subdomain.newdomain.com/page.htm Other Background: setup is between two different servers with different IP ranges although DNS cluster is on between all servers the newdomain.com is set up with its own unique IP (which is on the A records for the subdomains, the subdomains work as expected/normal) the DNS entry is correct (cdn CNAME subdomain.newdomain.com.) ie the end period is included a DNS lookup on the CNAME externally reports back as subdomain.newdomain.com. as the record Does anyone know what DNS entries I am missing to get this working correctly ? Note: I do not want to just put a redirect between domains as I need the content of subdomain.newdomain.com/content.html to be visible via the URL of cdn.xyz.com/content.html also I can just use some redirects on newdomain.com to achieve what I am after but would prefer to just get the DNS correct. EDIT Current DNS cdn CNAME subdomain.newdomain.com. || CNAME entry for domain1 subdomain A XXX.XXX.XXX.XXX || A record entry for working subdomain pointing to unique IP What should happen is that cdn.domain1.com - subdomain.newdomain.com What is happening is cdn.domain1.com - newdomain.com (ie. the root not the subdomain) EDIT 2 Actually if its easier I am trying to emulate a simple cloud setup like Rackspace Containers (which I assume is similar to Buckets on AWS). although it is not for cloud storage Where a container has a url reference of hd62321678d323.rackspace.com (in truth they are much longer) so I can use a CNAME record of: cdn CNAME hd62321678d323.rackspace.com. so that http://cdn.mydomain.com/myfile.jpg displays content from http://hd62321678d323.rackspace.com/myfile.jpg

  • ADSIEdit Cleanup After Exchange 2003 Crash During Transition To Exchange 2010

    - by ThaKidd
    Hello all. I would value some input from a few Exchange 2010 experts. I have almost completed the transition from Exchange 2003 Standard to Exchange 2010 Standard. Everything went smoothly until I tried to uninstall Exchange 2003. At that point the server bit the dust and died completely. I now have NO access to the old Exchange System Management MMC as I am running Windows 2008 SR2 and Windows 7 only. I can only fix this with ADSIEdit, EMShell, and EMConsole. I have used the 2010 shell to move/remove/verify that all mailboxes, public folders and OAB are hosted on Exchange 2010. I also verified that the routing connector has been deleted. The only two things that were not done was to remove the Recipient Update Service and actually perform the removal of the 2003 software. I have spent a lot of time going through ASDIedit and have located the old Administrative Group and the Exchange 2003 server listed under it. I also located the Recipient Update Service which includes two entries; Enterprise and my domain name. I have read that it is an unwise idea to remove the old administrative group so I won't bother messing with that. I am repeatedly getting three warnings in the Application Log. Both are from MSExchangeTransport EventID 5006 (Cannot find route to Mailbox Server OLDSERVER) and 5020 (The topology doesn't contain a route to Exchange 2000 Server or Exchange Server 2003) So my questions are: To clean out AD of the old Exchange 2003 info, can I delete the server name folder (Configuration - Services - Microsoft Exchange - ExchOrg - Administrative Groups - First Administrative Group - Servers - Old Server) and also delete the Update Recipient Service (Enterprise) and Update Recipient Service (DOMAIN) containers safely? Are there any additional items I need to address to ensure the AD is clean? Thanks in advance for your help!

  • How should secret files be pushed to an EC2 (on AWS) Ruby on Rails application?

    - by nikc
    How should secret files be pushed to an EC2 Ruby on Rails application using amazon web services with their elastic beanstalk? I add the files to a git repository, and I push to github, but I want to keep my secret files out of the git repository. I'm deploying to aws using: git aws.push The following files are in the .gitignore: /config/database.yml /config/initializers/omniauth.rb /config/initializers/secret_token.rb Following this link I attempted to add an S3 file to my deployment: http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/customize-containers.html Quoting from that link: Example Snippet The following example downloads a zip file from an Amazon S3 bucket and unpacks it into /etc/myapp: sources: /etc/myapp: http://s3.amazonaws.com/mybucket/myobject Following those directions I uploaded a file to an S3 bucket and added the following to a private.config file in the .elasticbeanstalk .ebextensions directory: sources: /var/app/current/: https://s3.amazonaws.com/mybucket/config.tar.gz That config.tar.gz file will extract to: /config/database.yml /config/initializers/omniauth.rb /config/initializers/secret_token.rb However, when the application is deployed the config.tar.gz file on the S3 host is never copied or extracted. I still receive errors that the database.yml couldn't be located and the EC2 log has no record of the config file, here is the error message: Error message: No such file or directory - /var/app/current/config/database.yml Exception class: Errno::ENOENT Application root: /var/app/current

  • Configure J2EE Agent with OpenAM behind Reverse Proxy

    - by Troy
    I have a reverse proxy with two SSL enabled NamedVirtualHosts on different ports. Both containers on each internal host is GF 2.1.1. Proxy configuration as follows: Proxy URL -> Internal URL https://apps.mydomain.com -> http://apps.internal.com https://secure.otherdomain.com:8080/ -> http://secure.internal.com I initially tried configuring the J2EE agent in OpenAM and the web app container to use the internal URLs (I appended /openam and /agentapp respectively). However, I received the following errors when trying to access a secured application such as https://apps.mydomain.com/webapp. java.lang.RuntimeException: Failed to load configuration: ApplicationSSOTokenProvider.getApplicationSSOToken(): Unable to get Application SSO Token A second attempt gives the following error: java.lang.NoClassDefFoundError: Could not initialize class com.sun.identity.agents.filter.AmFilterManager Along with these in the agent debug.out: ERROR: Failed to obtain auth service url from server: null://null:null ... SiteMonitor: Site URL http://secure.internal.com/openam/namingservice is not available. If I specify the server and agent urls using the proxy urls, then the agent appears to be working and I am redirected to the OpenAM login page. However, the goto in the URL is http://apps.mydomain.com/webapp instead of https://apps.mydomain.com/webapp (missing https). So after authentication, the redirect fails. Now I could possibly get by with mod_rewrite, but it feels hackish and I really want to know what's going on. Any ideas?

  • Permissions won't cascade more than 1 level

    - by Jovin_
    Running Windows Small Business Server 2011 I have a file structure with a lot of sub folders (sometimes 5-6 levels deep). I have created access groups to grant access to my users, and also deny groups to deny access to others. X Access & X Deny. These allow or deny access to a mapped network drive X: On the server I put in the groups with Full Control Allow for X Access and Full Control Deny for X Deny, I also tick the box "Apple these permissions to objects and/or containers within this container only" and have ensured that "Apply to:" is "This folder, subfolders and files". But for some reason the permissions will only apply to the next level of folders & files. ex. structure: X: Folder 1 Folder 1a Folder 2 Folder 2a If I apply the permissions to X: it'll only go to Folder 1 & 2, not 1a and 2a, I then need to manually apply the permissions to these too. Is this working as intended or am I doing something wrong?

  • Default IPv6 route on debian squeeze does not come up after boot

    - by Georg Bretschneider
    I have a problem with my default IPv6 route not coming up after boot on a Debian Squeeze system. This is my config (/etc/network/interfaces): # Loopback device: auto lo iface lo inet loopback iface lo inet6 loopback # device: br0 auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 88.198.62.xx broadcast 88.198.62.63 netmask 255.255.255.224 gateway 88.198.62.33 up route add -net 88.198.62.32 netmask 255.255.255.224 gw 88.198.62.33 br0 iface br0 inet6 static address 2a01:4f8:131:10x::2 netmask 64 gateway 2a01:4f8:131:100::1 up route -A inet6 add 2a01:4f8:131:100::1/59 dev br0 My inet comes up alright, but I have to exec the route command manually after boot to make IPv6 work. Otherwise I can't even reach my gateway. This is the output of ip -6 route show after boot: 2a01:4f8:131:10x::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 unreachable fe80::/64 dev lo proto kernel metric 256 error -101 mtu 16436 advmss 16376 hoplimit 4294967295 fe80::/64 dev br0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 I already tried it with: up ip -6 route add 2a01:4f8:131:100::1 dev br0 up ip -6 route add default via 2a01:4f8:131:100::1 dev br0 in /etc/network/interfaces, but with the same results. If I execute those commands manually on my shell, everything starts working nicely. And yes, I tried with post-up instead of up, too. Only other changes I made was to activate ip forwarding for IPv6, because I want to run some LXC containers on that system.

  • On Windows machines, what is the typical toolchain for remote maintenance?

    - by Hanno Fietz
    I need to deploy PHP and Python code and the appropriate environment (web server, db server) to remote Windows systems, and I don't know what toolchain would be the equivalent to ssh, scp, bash and the like. So, basically, what I need to be able to do is the following: access remote Windows with the appropriate privileges in a secure manner, like I routinely do with ssh (I don't even know whether that would be a text or graphic interface on Windows). remotely install software: Apache or IIS, MySQL or Postgres, Python or PHP copy files from remote (the application we're deploying) remotely configure the machine to run regular tasks (e. g. checking for updates to the application) automate tasks like downloading files from a designated place The main question is probably how I get onto the machine securely in the first place, and then the rest is general Windows admin knowledge, which probably is too broad a scope to fit into one question. I have years of experience with maintaining Linux boxes and I have used tools of varying sophistication on those, ranging from plain scping of PHP files to deployment of Java application containers and even full VMs with Vagrant. On Windows, I'm a complete noob, and I don't even know where to start. I have installed Apache, MySQL , PHP on a desktop machine maybe twice in my life, that's about it. Bonus points for things that work from a Linux machine at my end, but I could run a VM and do everything from there.

  • Anonymous Login attemps from IPs all over Asia, how do I stop them from being able to do this?

    - by Ryan
    We had a successful hack attempt from Russia and one of our servers was used as a staging ground for further attacks, actually somehow they managed to get access to a Windows account called 'services'. I took that server offline as it was our SMTP server and no longer need it (3rd party system in place now). Now some of our other servers are having these ANONYMOUS LOGIN attempts in the Event Viewer that have IP addresses coming from China, Romania, Italy (I guess there's some Europe in there too)... I don't know what these people want but they just keep hitting the server. How can I prevent this? I don't want our servers compromised again, last time our host took our entire hardware node off of the network because it was attacking other systems, causing our services to go down which is really bad. How can I prevent these strange IP addresses from trying to access my servers? They are Windows Server 2003 R2 Enterprise 'containers' (virtual machines) running on a Parallels Virtuozzo HW node, if that makes a difference. I can configure each machine individually as if it were it's own server of course... UPDATE: New login attempts still happening, now these ones are tracing back to Ukraine...

  • Why does BitLocker need a minimum volume size of 64 MB?

    - by Iszi
    Since the future of TrueCrypt appears to be still unclear, I figured I'd try to get my stuff migrated into BitLocker at least for the time being. I nearly never have to access my encrypted data from anything that's not BitLocker-capable, so cross-platform compatibility isn't a big deal to me at this time. However, I am having a bit of an issue understanding the minimum requirement of a 64 MB volume. With TrueCrypt, I was able to protect small files (and most of my protected files are fairly small) in containers down to 300 KB or even less. When I finally created a VHD of an appropriate size last night (100 MB), it seemed the file system itself only took up about 3 MB and encrypting it with BitLocker didn't appear to take up any more. While 3 MB is still an order of magnitude larger than the smallest volume I could make with TrueCrypt, it's still relatively reasonable in comparison to 64 MB. This is an especially large amount of overhead (and largely wasted at that, since it's mostly empty space for now) when I consider that some of these volumes will be stored and synced in the cloud. What possible reasons could BitLocker have for needing volumes to be 64 MB large, when it's not even appearing to use that space? BitLocker FAQ on TechNet

  • Bonnie does not provide speed for Sequential Input / Block

    - by Lqp1
    I'm using ProxmoxVE and I would like to run some benchmarks regarding performances of this product. One of these benchmarks is bonnie++ ; it runs very well in a VM (qemu-kvm) but when I run it in a conainer (openVZ), it does not provide me reading speed (only writing). I don't understand why... Does anyone know what's happenning ? VMs ans Containers are Debian 7.4. Here's the output of bonnie in the container: root@ct2:/# bonnie++ -u root Using uid:0, gid:0.
