• Algorithm for tracking progress of controller method running in background

  - by SilentAssassin

  I am using Codeigniter framework for PHP on Windows platform. My problem is I am trying to track progress of a controller method running in background. The controller extracts data from the database(MySQL) then does some processing and then stores the results again in the database. The complete aforesaid process can be considered as a single task. A new task can be assigned while another task is running. The newly assigned task will be added in a queue. So if I can track progress of the controller, I can show status for each of these tasks. Like I can show "Pending" status for tasks in the queue, "In Progress" for tasks running and "Done" for tasks that are completed. Main Issue: Now first thing I need to find is an algorithm to track the progress of how much amount of execution the controller method has completed and that means tracking how much amount of method has completed execution. For instance, this PHP script tracks progress of array being counted. Here the current state and state after total execution are known so it is possible to track its progress. But I am not able to devise anything analogous to it in my case. Maybe what I am trying to achieve is programmtically not possible. If its not possible then suggest me a workaround or a completely new approach. If some details are pending you can mention them. Sorry for my ignorance this is my first post here. I welcome you to point out my mistakes. EDIT: Database outline: The URL(s) and keyword(s) are first entered by user which are stored in a database table called link_master and keyword_master respectively. Then keywords are extracted from all the links present in this table and compared with keywords entered by user and their frequency is calculated which is the final result. And the results are stored in another table called link_result. Now sub-links are extracted from the domain links and stored in a table called sub_link_master. Now again the keywords are extracted from these sub-links and the corresponding results are stored in a table called sub_link_result. The number of records cannot be defined beforehand as the number of links on any web page can be different. Only the cardinality of *link_result* table can be known which will be equal to multiplication of number of keyword(s) and URL(s) . I insert multiple records at a time using this resource. Controller outline: The controller extracts keywords from a web page and also extracts keywords from all the links present on that page. There is a method called crawlLink. I used Rolling Curl to extract keywords and web page content. It has callback function which I used for extracting keywords alongwith generating results and extracting valid sub-links. There is a insertResult method which stores results for links and sub-links in the respective tables. Yes, the processing depends on the number of records. The more the number of records, the more time it takes to execute: Consider this scenario: Number of Domain Links = 1 Number of Keywords = 3 Number of Domain Links Result generated = 3 (3 x 1 as described in the question) Number of Sub Links generated = 41 Number of Sub Links Result = 117 (41 x 3 = 123 but some links are not valid or searchable) Approximate time taken for above process to complete = 55 seconds. The above result is for a single link. I want to track the progress of the above results getting stored in database. When all results are stored, the task is complete. If results are getting stored, the task is In Progress. I am not clear how can I track this progress.

• apt-get upgrade stuck at the same package

Update After following instructions in the answer by @lpanebr, it is now stuck at the linux-firmware package. So, maybe it's a more general problem than being related to specific package(s)? Although it did download some packages without problems before getting stuck at linux-firmware.

• Stepping outside Visual Studio IDE [Part 2 of 2] with Mono 2.6.4

  - by mbcrump

  Continuing part 2 of my Stepping outside the Visual Studio IDE, is the open-source Mono Project. Mono is a software platform designed to allow developers to easily create cross platform applications. Sponsored by Novell (http://www.novell.com/), Mono is an open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime. A growing family of solutions and an active and enthusiastic contributing community is helping position Mono to become the leading choice for development of Linux applications. So, to clarify. You can use Mono to develop .NET applications that will run on Linux, Windows or Mac. It’s basically a IDE that has roots in Linux. Let’s first look at the compatibility: Compatibility If you already have an application written in .Net, you can scan your application with the Mono Migration Analyzer (MoMA) to determine if your application uses anything not supported by Mono. The current release version of Mono is 2.6. (Released December 2009) The easiest way to describe what Mono currently supports is: Everything in .NET 3.5 except WPF and WF, limited WCF. Here is a slightly more detailed view, by .NET framework version: Implemented C# 3.0 System.Core LINQ ASP.Net 3.5 ASP.Net MVC C# 2.0 (generics) Core Libraries 2.0: mscorlib, System, System.Xml ASP.Net 2.0 - except WebParts ADO.Net 2.0 Winforms/System.Drawing 2.0 - does not support right-to-left C# 1.0 Core Libraries 1.1: mscorlib, System, System.Xml ASP.Net 1.1 ADO.Net 1.1 Winforms/System.Drawing 1.1 Partially Implemented LINQ to SQL - Mostly done, but a few features missing WCF - silverlight 2.0 subset completed Not Implemented WPF - no plans to implement WF - Will implement WF 4 instead on future versions of Mono. System.Management - does not map to Linux System.EnterpriseServices - deprecated Links to documentation. The Official Mono FAQ’s Links to binaries. Mono IDE Latest Version is 2.6.4 That's it, nothing more is required except to compile and run .net code in Linux. Installation After landing on the mono project home page, you can select which platform you want to download. I typically pick the Virtual PC image since I spend all of my day using Windows 7. Go ahead and pick whatever version is best for you. The Virtual PC image comes with Suse Linux. Once the image is launch, you will see the following: I’m not going to go through each option but its best to start with “Start Here” icon. It will provide you with information on new projects or existing VS projects. After you get Mono installed, it's probably a good idea to run a quick Hello World program to make sure everything is setup properly. This allows you to know that your Mono is working before you try writing or running a more complex application. To write a "Hello World" program follow these steps: Start Mono Development Environment. Create a new Project: File->New->Solution Select "Console Project" in the category list. Enter a project name into the Project name field, for example, "HW Project". Click "Forward" Click “Packaging” then OK. You should have a screen very simular to a VS Console App. Click the "Run" button in the toolbar (Ctrl-F5). Look in the Application Output and you should have the “Hello World!” Your screen should look like the screen below. That should do it for a simple console app in mono. To test out an ASP.NET application, simply copy your code to a new directory in /srv/www/htdocs, then visit the following URL: http://localhost/directoryname/page.aspx where directoryname is the directory where you deployed your application and page.aspx is the initial page for your software. Databases You can continue to use SQL server database or use MySQL, Postgress, Sybase, Oracle, IBM’s DB2 or SQLite db. Conclusion I hope this brief look at the Mono IDE helps someone get acquainted with development outside of VS. As always, I welcome any suggestions or comments.

• Advice on refactoring PHP Project

  - by b0x

  I have a small SAS ERP that was written some years ago using PHP. At that time, it didn't use any framework, but the code isn't a mess. Nowadays, the project grows and I’m now working with 3 more programmers. Often, they ask to me why we don’t migrate to a framework such as Laravel. Although I'd love trying Laravel, I’m a small business and I don't have time nor money to stop and spend a whole year building everything from scratch. I need to live and pay the bills. So, I've read a lot about this matter, and I decided that doing a refactoring is the best way to do it. Also, I'm not so sure that a framework will make things easy. Business goals are: Make the code easier to new hired programmers Separate the "view", in order to: release different versions of this product (using the same code), but under different brands and websites at the minimum cost (just changing view) release different versions to fit mobile/tablet. Make different types of this product, selling packages as if they were plugins. Develop custom packages for some costumers (like plugins/addon's that they can buy to put on the main application). Code goals: Introduce best pratices, standards for everyone Try to build my own MVC structure Improve validation of data/forms (today they are mixed in both ajax and classes) Create automated testing routines for quality assurance. My current structure project: class\ extra\ hd\ logs\ public_html\ public_html\includes\ public_html\css|js|images\ class\ There are three types of classes. They are all “autoloaded” with something similar with PSR-0, but I don’t use namespaces. 1. class.Something.php Connects to Database using specific methods. I.e: Costumer-list(); It uses “class.Db.php”, that it’s an abstraction of mysql on every method. 2. class.SomethingProc.php Do things that “join” things that come from “class.Something.php”. Like IF/ELSE, math operations. 3. class.SomethingHTML.php The classes with “HTML” suffix implements only static methods and HTML code only. A real life example: All the programmers need to use $cSomething ($c to class) and $arrSomething (to array). Costumer.php (view) <?php $cCosumter = new Costumer(); $arrCostumer = $cCostumer->list(); echo CostumerHTML::table($arrCostumer); ?> Extra\ Store 3rdparty projects/classes from others, such MPDF, PHPMailer, etc. Hd\ Store user’s files outsite wwwroot dir. Logs\ Store phplogs and the system itself logs (We have a static Log::error() method, that we put in every method of every class) Public_html\ Stores the files that people use. Public_html\includes\ Store the main “config.php” file and all files that do “ajax things” ajax.Costumer.php, for example. Help is needed ;) So, as you can see we have some standards, and also for database things. But I want to write a manual of our rules. Something that I can give to any new programmer at my company and he can go on. This is not totally a mess, but it could be better seeing the new practices. What could I do to separate this as MVC, to have multiple views. Could you give me some tips considering my goals? Keep im mind the different products/custom things for specific costumers without breaking the main application. URL for tutorials, books, etc, would be nice.

• Type of computer for a developer on the road

  - by nabucosound

  Hi developers: I am planning to be traveling through eurasia and asia (russia, china, korea, japan, south east asia...) for a while and, although there are plenty of marvelous things to see and to do, I must keep on working :(. I am a python developer, dedicated mainly to web projects. I use django, sqlite3, browsers, and ocassionaly (only if I have no choice) I install postgres, mysql, apache or any other servers commonly used in the internets. I do my coding on vim, use ssh to connect, lftp to transfer files, IRC, grep/ack... So I spend most of my time in the terminal shells. But I also use IM or Skype to communicate with my clients and peers, as well as some other software (that after all is not mandatory for my day-to-day work). I currently work with a Macbook Pro (3 years old now) and so far I am very happy with the performance. But I don't want to carry it if I am going to be "on transit" for long time, it is simply huge and heavy for what I am planning to load in my rather small backpack (while traveling, less is more, you know). So here I am reading all kind of opinions about netbooks, because at first sight this is the kind of computer I thought I had to choose. I am going to use Linux for it, Microsoft is not my cup of tea and Mac is not available for them, unless I were to buy a Macbook air, something that I won't do because if I am robbed or rain/dust/truck loaders break it I would burst in tears. I am concerned about wifi performance and connectivity, I am going to use one of those linux distros/tools to hack/test on "open" networks (if you know what I mean) in case I am not in a place with real free wifi access and I find myself in an emergency. CPU speed should be acceptable, but since I don't plan to run Photoshop or expensive IDEs, I guess most of the time I won't be overloading the machine. Apart from this, maybe (surely) I am missing other features to consider. With that said (sorry about the length) here it comes my question, raised from a deep ignorance regarding the wars betweeb betbooks vs notebooks (I assume tablet PCs are not for programming yet): If I buy a netbook will I have to throw it away after 1 month on the road and buy a notebook? Or will I be OK? Thanks! Hector Update I have received great feedback so far! I would like to insist on the fact that I will be traveling through many different countries and scenarios. I am sure that while in Japan I will be more than fine with anything related to technology, connectivity, etc. But consider that I will be, for example, on a train through Russia (transsiberian) and will cross Mongolia as well. I will stay in friends' places sometimes, but most of the time I will have to work from hostel rooms, trains, buses, beaches (hey this last one doesn't sound too bad hehe!). I think some of your answers guys seem to focus on the geek part but loose the point of this "on the road" fact. I am very aware and agree that netbooks suck compared to notebooks, but what I am trying to do here is to find a balance and discover your experiences with netbooks to see first hand if a netbook will be a fail in the mid-long term of the trip for my purposes. So I have resumed the main concepts expressed here on this small list, in no particular order: keyboard/touchpad feel: I use vim so no need of moving mouse pointers that much, unless I am browsing the web, but intensive use of keyboard screen real state: again, terminal work for most of the time battery life: I think something very important weight/size: also very important looks not worth stealing it, don't give a shit if it is lost/stolen/broken: this may depend on kind of person, your economy, etc. Also to prevent losing work, I will upload EVERYTHING to the cloud whenever I'll have a chance. wifi: don't want to discover my wifi is one of those that cannot deal with half the routers on this planet or has poor connectivity. Thanks again for your answers and comments!

• Web Developer - How to enhance my skillset?

  - by atif089

  First of all pardon my English. I am not a native English speaker I have been a Web Developer for the past 4 years. In these 4 years I have spent my time on the internet to learn things. My current skillset comprises of HTML CSS PHP MySQL jQuery (I would not say js and rather say jQuery because I am good at using jQuery and bad with plain javascript.) The above things seemed like an easier part of my life as I quickly learned them. But now I would really like to enhance my skillset and I am pretty confused which way to move ahead considering that I have to learn things using the web and references on my own. Design My first option is towards design. Shall I get started with design and start using Adobe Illustrator, Photoshop, Flash, Flex. Designing along with my previous skills looks like a money maker to me. As both are co-related to each other when web design is considered. And its easier to learn the first 2 and I hope I can get tutorials for the last 2 as well. Marketing A lot of my existing clients asked me if I do SEO. So this looked as a good field to me as well. I cannot estimate the scope of SEO but I assume it has a long future. Since I am business minded as well and there are a lot of tutorials around, should I start with SEO, SEM, Social Media, PPC or whatever it consists of. Software Development The complex plight and hardest thing (perhaps) but the easiest way to find a decent job in my location. If I go for software development what platform should be that I should be ideally going after? Should it be C# for windows development, or ASP.NET (once again enhances my skill set), J2EE (there are a lot of jobs for J2EE developers here) or plain C and C++. Also I think it is difficult to learn software languages right from Hello World, using internet? I have no clue how I learned PHP but I am sort of a pro now, but these other languages seems like a disaster to me? I cant figure out the reason if its because PHP is easier or there was a lot of tutorials around for PHP. Anyways is it also possible to learn software development right from Hello World using the web? Database / Server (Linux) / Network Administration Seems like a job with a decent pay but less number of jobs and a bit harder to learn online. (not sure) What should be the right track I should move ahead. P.S - Age is not a constraint for me as I am between 20-21, and I come from an IT background. I know quite little basics about C (upto structures) C++ (upto objects, I was not able to understand templates) Core Java (some basics and OOP concept) RDBMS Visual Basic 6 (used to do this long back) UNIX (a bunch of commands like who, finger, chmod, ls and a bit of #bash) Or is there anything else that I left out? I need you guys to please give me a feedback and the reason why I should select that field.

• Designing An ACL Based Permission System

  - by ryanzec

  I am trying to create a permissions system where everything is going to be stored in MySQL (or some database) and pulled using PHP for a project management system I am building.  I am right now trying to do it is an ACL kind of way.  There are a number key features I want to be able to support: 1.  Being able to assign permissions without being tied to a specific object. The reason for this is that I want to be able to selectively show/hide elements of the UI based on permissions at a point where I am not directly looking at a domain object instance.  For instance, a button to create a new project should only should only be shown to users that have the pm.project.create permission but obviously you can assign a create permission to an domain object instance (as it is already created). 2.  Not have to assign permissions for every single object. Obviously creating permissions entries for every single object (projects, tickets, comments, etc…) would become a nightmare to maintain so I want to have some level of permission inheritance. *3.  Be able to filter queries based on permissions. This would be a really nice to have but I am not sure if it is possible.  What I mean by this is say I have a page that list all projects.  I want the query that pulls all projects to incorporate the ACL so that it would not show projects that the current user does not have pm.project.read access to.  This would have to be incorporated into the main query as if it is a process that is done after that main query (which I know I could do) certain features like pagination become much more difficult. Right now this is my basic design for the tables: AclEntities id - the primary key key - the unique identifier for the domain object (usually the primary key of that object) parentId - the parent of the domain object (like the project object if this was a ticket object) aclDomainObjectId - metadata about the domain object AclDomainObjects id - primary key title - simple string to unique identify the domain object(ie. project, ticket, comment, etc…) fullyQualifiedClassName - the fully qualified class name for use in code (I am using namespaces) There would also be tables mapping AclEntities to Users and UserGroups. I also have this interface that all acl entity based object have to implement: IAclEntity getAclKey() - to the the unique key for this specific instance of the acl domain object (generally return the primary key or a concatenated string of a composite primary key) getAclTitle() - to get the unique title for the domain object (generally just returning a static string) getAclDisplayString() - get the string that represents this entity (generally one or more field on the object) getAclParentEntity() - get the parent acl entity object (or null if no parent) getAclEntity() - get the acl enitty object for this instance of the domain object (or null if one has not been created yet) hasPermission($permissionString, $user = null) - whether or not the user has the permission for this instance of the domain object static getFromAclEntityId($aclEntityId) - get a specific instance of the domain object from an acl entity id. Do any of these features I am looking for seems hard to support or are just way off base? Am I missing or not taking in account anything in my implementation? Is performance something I should keep in mind?

• Welcome to BlogEngine.NET 2.9 using Microsoft SQL Server

  If you see this post it means that BlogEngine.NET 2.9 is running and the hard part of creating your own blog is done. There is only a few things left to do. Write Permissions To be able to log in to the blog and writing posts, you need to enable write permissions on the App_Data folder. If you’re blog is hosted at a hosting provider, you can either log into your account’s admin page or call the support. You need write permissions on the App_Data folder because all posts, comments, and blog attachments are saved as XML files and placed in the App_Data folder.  If you wish to use a database to to store your blog data, we still encourage you to enable this write access for an images you may wish to store for your blog posts.  If you are interested in using Microsoft SQL Server, MySQL, SQL CE, or other databases, please see the BlogEngine wiki to get started. Security When you've got write permissions to the App_Data folder, you need to change the username and password. Find the sign-in link located either at the bottom or top of the page depending on your current theme and click it. Now enter "admin" in both the username and password fields and click the button. You will now see an admin menu appear. It has a link to the "Users" admin page. From there you can change the username and password.  Passwords are hashed by default so if you lose your password, please see the BlogEngine wiki for information on recovery. Configuration and Profile Now that you have your blog secured, take a look through the settings and give your new blog a title.  BlogEngine.NET 2.9 is set up to take full advantage of of many semantic formats and technologies such as FOAF, SIOC and APML. It means that the content stored in your BlogEngine.NET installation will be fully portable and auto-discoverable.  Be sure to fill in your author profile to take better advantage of this. Themes, Widgets & Extensions One last thing to consider is customizing the look of your blog.  We have a few themes available right out of the box including two fully setup to use our new widget framework.  The widget framework allows drop and drag placement on your side bar as well as editing and configuration right in the widget while you are logged in.  Extensions allow you to extend and customize the behaivor of your blog.  Be sure to check the BlogEngine.NET Gallery at dnbegallery.org as the go-to location for downloading widgets, themes and extensions. On the web You can find BlogEngine.NET on the official website. Here you'll find tutorials, documentation, tips and tricks and much more. The ongoing development of BlogEngine.NET can be followed at CodePlex where the daily builds will be published for anyone to download.  Again, new themes, widgets and extensions can be downloaded at the BlogEngine.NET gallery. Good luck and happy writing. The BlogEngine.NET team

Partition-level ADO and compression are supported if partitioned on the end-time columns. Row-level policies for ADO are not supported for in-database archiving. Partition-level ADO and compression are supported if partitioned on the ORA_ARCHIVE_STATE column. Custom policies (user-defined functions) for ADO are not supported if the policies default at the tablespace level. ADO does not perform checks for storage space in a target tablespace when using storage tiering. ADO is not supported on tables with object types or materialized views. ADO concurrency (the number of simultaneous policy jobs for ADO) depends on the concurrency of the Oracle scheduler. If a policy job for ADO fails more than two times, then the job is marked disabled and the job must be manually enabled later. Policies for ADO are only run in the Oracle Scheduler maintenance windows. Outside of the maintenance windows all policies are stopped. The only exceptions are those jobs for rebuilding indexes in ADO offline mode.

• networking through openstack installed on vm

  - by Mandar Katdare

  I am trying to set up a test installation of Openstack on a Ubuntu 12.04 VM running on a ESXi server. So far I have been able to launch the VMs on the ESXi, however am unable to assign IP addresses to them. As the VM with the Openstack installation has a single public IP, I wish to assign IPs to the VMs create through Openstack so that they can directly interact with the public network itself without having a separate private network. So I feel that bridging would not be the correct option here. But am unable to find the correct documents to go ahead with such an install. My ifconfig looks as follows: eth0 Link encap:Ethernet HWaddr 00:0c:29:6f:8a:d7 inet addr:192.168.4.167 Bcast:192.168.4.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe6f:8ad7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:391640 errors:33 dropped:98 overruns:0 frame:0 TX packets:545044 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:40303931 (40.3 MB) TX bytes:763127348 (763.1 MB) Interrupt:18 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:146127 errors:0 dropped:0 overruns:0 frame:0 TX packets:146127 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:799815763 (799.8 MB) TX bytes:799815763 (799.8 MB) virbr0 Link encap:Ethernet HWaddr 8a:80:33:32:63:a0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) The eth0 is the adapter that I intend to use for all communication.

Can anyone advice me about how to proceed? Thanks, Mandar

• Coldfusion autorestart

  - by Comcar

  Coldfusion is automatically restarting, a lot. It comes in waves, everything seems fine for a while then the server struggles for a few minutes, restarts a lot then settles down again. I have Fusion Reactor installed, but when CF goes down FR stops logging so it's not really helping. Looking through the archived logs just shows gaps in the logs. These are all the occourances of the phrase "Coldfusion started" today. [root@server2 logs]# grep -i "Coldfusion started" server.log | grep "11/27/12" "Information","main","11/27/12","01:49:35",,"ColdFusion started" "Information","main","11/27/12","01:50:46",,"ColdFusion started" "Information","main","11/27/12","01:52:39",,"ColdFusion started" "Information","main","11/27/12","01:54:08",,"ColdFusion started" "Information","main","11/27/12","01:55:12",,"ColdFusion started" "Information","main","11/27/12","01:56:29",,"ColdFusion started" "Information","main","11/27/12","01:57:36",,"ColdFusion started" "Information","main","11/27/12","01:58:57",,"ColdFusion started" "Information","main","11/27/12","01:59:56",,"ColdFusion started" "Information","main","11/27/12","02:01:38",,"ColdFusion started" "Information","main","11/27/12","02:03:11",,"ColdFusion started" "Information","main","11/27/12","02:04:41",,"ColdFusion started" "Information","main","11/27/12","02:07:53",,"ColdFusion started" "Information","main","11/27/12","02:10:45",,"ColdFusion started" "Information","main","11/27/12","02:11:49",,"ColdFusion started" "Information","main","11/27/12","02:13:09",,"ColdFusion started" "Information","main","11/27/12","02:14:18",,"ColdFusion started" "Information","main","11/27/12","02:15:44",,"ColdFusion started" "Information","main","11/27/12","02:17:06",,"ColdFusion started" "Information","main","11/27/12","02:34:19",,"ColdFusion started" "Information","main","11/27/12","03:01:20",,"ColdFusion started" "Information","main","11/27/12","05:25:59",,"ColdFusion started" "Information","main","11/27/12","06:30:48",,"ColdFusion started" "Information","main","11/27/12","06:36:20",,"ColdFusion started" "Information","main","11/27/12","09:34:07",,"ColdFusion started" "Information","main","11/27/12","09:35:39",,"ColdFusion started" "Information","main","11/27/12","09:36:41",,"ColdFusion started" "Information","main","11/27/12","09:39:15",,"ColdFusion started" "Information","main","11/27/12","09:40:42",,"ColdFusion started" "Information","main","11/27/12","09:42:55",,"ColdFusion started" "Information","main","11/27/12","09:44:23",,"ColdFusion started" "Information","main","11/27/12","09:46:18",,"ColdFusion started" "Information","main","11/27/12","09:47:35",,"ColdFusion started" "Information","main","11/27/12","09:48:53",,"ColdFusion started" "Information","main","11/27/12","09:50:04",,"ColdFusion started" "Information","main","11/27/12","09:51:51",,"ColdFusion started" "Information","main","11/27/12","09:53:05",,"ColdFusion started" "Information","main","11/27/12","09:54:24",,"ColdFusion started" "Information","main","11/27/12","09:55:28",,"ColdFusion started" "Information","main","11/27/12","09:56:38",,"ColdFusion started" "Information","main","11/27/12","09:58:03",,"ColdFusion started" "Information","main","11/27/12","09:59:03",,"ColdFusion started" "Information","main","11/27/12","10:04:37",,"ColdFusion started" "Information","main","11/27/12","12:04:02",,"ColdFusion started" I've been looking at the live server metrics in FR on a second screen all day, the CPU, Memory and requests all seemed fine about 12 midday, then the server rebooted. Looking at the logs for the hour between 9am and 10am (more than 15 restarts in the hour), the CPU never went over 44% usage and the Memory never exceeded 53% usage - in the recorded stats at least. There is no JDBC tracking at the moment, so I'll add that to tracking and see if it's MySQL causing a problem, but can anyone help me narrow down the problem, what would cause Cold Fusion to auto restart, and I'm assuming the auto restart is only happening because Fusion Reactor is installed. It's a Red Hat 5 LAMP stack running Coldfusion 9 and Fusion Reactor 4.5.2

• MariaDB doesn't upgrade, 2 versions are installed

  I have a server running on Debian wheezy with MaraiDB and OwnCloud. Few days ago, I wanted to update the packages because of the OwnCloud updates but something went wrong. Usually in this case I'd probably try to remove and again install the problematic packages, but on a server which is used by different people it doesn't seem like a valid solution anymore.

  I'm running a LAMP stack, with no phpmyadmin (yes) installed. While poking through my apache server longs i noticed things like. 74.208.75.29 - - [16/Mar/2010:02:53:45 +0800] "POST http://74.208.75.29:6667/ HTTP/1.0" 404 481 "-" "-" 74.208.75.29 - - [16/Mar/2010:02:53:45 +0800] "CONNECT 74.208.75.29:6667 HTTP/1.0" 405 547 "-" "-" 66.184.178.58 - - [16/Mar/2010:13:27:59 +0800] "GET / HTTP/1.1" 200 1170 "-" "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)" 200.78.247.148 - - [16/Mar/2010:15:26:05 +0800] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 506 "-" "-" 206.47.160.224 - - [16/Mar/2010:17:27:57 +0800] "GET / HTTP/1.1" 200 1170 "-" "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:02 +0800] "GET //phpmyadmin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 480 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:03 +0800] "GET //pma/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 476 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:04 +0800] "GET //admin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 478 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:05 +0800] "GET //dbadmin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 479 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:05 +0800] "GET //mysql/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 479 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" 190.220.14.195 - - [17/Mar/2010:01:28:06 +0800] "GET //php-my-admin/config/config.inc.php?p=phpinfo(); HTTP/1.1" 404 482 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)" What exactly is happening? is it a really lame attempt at hacking in? Should i bother blocking the ip addresses these are from, or just leave it?

• Apache taking up too much CPU

  - by andrewtweber

  I'm trying to manage a server on Amazon for a network of sites that receives about 100 million pageviews per month. Unfortunately, nobody out of my team of 5 developers has much server admin experience. Right now we have the MaxClients set to 1400. Currently our traffic is about average, and we have 1150 total Apache processes running, which use about 2% CPU each! Out of those 1150, 800 of them are currently sleeping, but still taking up CPU. I'm sure there are ways to optimize this. I have a few thoughts: It appears Apache is creating a new process for every single connection. Is this normal? Is there a way to more quickly kill the sleeping processes? Should we turn KeepAlive on? Each page loads about 15-20 medium-sized graphics and a lot of javascript/css. So, here's our Apache setup. We do plan on contracting a server admin asap, but I would really appreciate some advice until we can find someone.

• Apache : Illegal override option FileInfo

  - by Kave

  I have installed a new Ubuntu 12.04 Server and setup Apache and MySQL. I am just trying to replicate what I have in my current server and came across one single problem. - FileInfo Within these two files below: /etc/apache2/sites-available/default-ssl /etc/apache2/sites-available/default I need to add some overrides for the apache server. Original: <Directory /var/www/MySite> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> New: <Directory /var/www/MySite> Options Indexes FollowSymLinks MultiViews AllowOverride FileInfo, Indexes Order allow,deny allow from all </Directory> I have installed the following mods for Apache: sudo apt-get install lamp-server^ -y sudo apt-get install apache2.2-common apache2-utils openssl openssl-blacklist openssl-blacklist-extra -y sudo apt-get install curl libcurl3 libcurl3-dev php5-curl -y sudo apt-get install php5-tidy -y sudo apt-get install php5-gd -y sudo apt-get install php-apc -y sudo apt-get install memcached -y sudo apt-get install php5-memcache -y sudo a2enmod ssl sudo a2enmod rewrite sudo a2enmod headers sudo a2enmod expires sudo a2enmod php5 So When I do a restart with AllowOverride None, its all ok. sudo /etc/init.d/apache2 restart * Restarting web server apache2 ... waiting [OK] But as soon as I change the AllowOverride to FileInfo, Indexes Syntax error on line 11 of /etc/apache2/sites-enabled/000-default: Illegal override option FileInfo, Action 'configtest' failed. The Apache error log may have more information. ...fail! I can't see anything unusual in the error.log [Wed Jun 06 08:23:51 2012] [notice] caught SIGTERM, shutting down [Wed Jun 06 08:23:52 2012] [warn] RSA server certificate CommonName (CN) `mySite.com' does NOT match server name!?

Therefore this warning should be harmless. Have I missed something? Thanks,

• How to use bzdiff to find difference between 2 bzipped files with diff -I option?

  - by englebip

  I'm trying to do a diff on MySQL dumps (created with mysqldump and piped to bzip2), to see if there are changes between consecutive dumps. The followings are the tails of 2 dumps: tmp1: /*!40101 SET SQL_MODE=@OLD_SQL_MODE */; /*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */; /*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; /*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */; -- Dump completed on 2011-03-11 1:06:50 tmp2: /*!40101 SET SQL_MODE=@OLD_SQL_MODE */; /*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */; /*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; /*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */; -- Dump completed on 2011-03-11 0:40:11 When I bzdiff their bzipped version: $ bzdiff tmp?.bz2 10c10 < -- Dump completed on 2011-03-11 1:06:50 --- > -- Dump completed on 2011-03-11 0:40:11 According to the manual of bzdiff, any option passed on to bzdiff is passed on to diff. I therefore looked at the -I option that allows to define a regexp; lines matching it are ignored in the diff. When I then try: $ bzdiff -I'Dump' tmp1.bz2 tmp2.bz2 I get an empty diff. I would like to match as much as possible of the "Dump completed" line, though, but when I then try: $ bzdiff -I'Dump completed' tmp1.bz2 tmp2.bz2 diff: extra operand `/tmp/bzdiff.miCJEvX9E8' diff: Try `diff --help' for more information. Same thing happens for some variations: $ bzdiff '-IDump completed' tmp1.bz2 tmp2.bz2 $ bzdiff '-I"Dump completed"' tmp1.bz2 tmp2.bz2 $ bzdiff -'"IDump completed"' tmp1.bz2 tmp2.bz2 If I diff the un-bzipped files there is no problem: $diff -I'^[-][-] Dump completed on' tmp1 tmp2 gives also an empty diff. bzdiff is a shell script usually placed in /bin/bzdiff. Essentially, it parses the command options and passes them on to diff as follows: OPTIONS= FILES= for ARG do case "$ARG" in -*) OPTIONS="$OPTIONS $ARG";; *) if test -f "$ARG"; then FILES="$FILES $ARG" else echo "${prog}: $ARG not found or not a regular file" exit 1 fi ;; esac done [...] bzip2 -cdfq "$1" | $comp $OPTIONS - "$tmp" I think the problem stems from escaping the spaces in the passing of $OPTIONS to diff, but I couldn't figure out how to get it interpreted correctly. Any ideas? EDIT @DerfK: Good point with the ., I had forgotten about them... I tried the suggestion with the multiple level of quotes, but that is still not recognized: $ bzdiff "-I'\"Dump.completed.on\"'" tmp1.bz2 tmp2.bz2 diff: extra operand `/tmp/bzdiff.Di7RtihGGL'
