  • Script / App to unRAR files, and only delete the archives which were sucessfully expanded.

    - by Jeremy
    I have a cron job which runs a script to unrar all files in a certain directory (/rared for argument's sake) and place the expanded files in /unrared. I would like to change this script so that it deletes the original rar archives from /rared only if they successfully extracted. This does not mean that unrar has reported that they have been fully extracted, because I have had data corruption during decompression before. Ideally (pie-in-the-sky, just to give you an idea of what I'm shooting for,) the unrar program would include this functionality, comparing an expected md5sum value with the actual md5sum value and only deleting the archive if they match. I don't mind scripting this entire process if I have to, but there must be a better way than unraring twice and comparing md5sums.

  • TechEd 2012: Recap

    - by Tim Murphy
    TechEd this week was a great experience and I wanted to wrap it up with a summary post. First let me say a thank you to John and Jeff from GWB for supplying power, connectivity and a place to work in between sessions.  The blogging hub was a great experience in itself.  Getting to talk with other bloggers and other conference goers turned into a series of interesting conversations.  And where else can you almost end up in the day 1 highlights video? The sessions at TechEd were a mixed bag of value.  The Keynotes rocked, both figuratively and literally and most of the sessions that I want to were a good experience and had gems of information to take away.  There were a few exceptions though.  A couple of the sessions turned out to be sales jobs.  Nothing turns me off more than that (there will be some really honest comments on those surveys). TechEd re-enforced for me that much of the value is not in the sessions, but in the networking opportunities. I got to talk with several Microsoft team members and MVPs as well as some of the vendor representative for companies like Inrule and ComponentOne. Also got to expand both my local and extended community with discussions at meal times and waiting for sessions to start. I think this is one of the benefits that a lot of people don’t take advantage of in these conferences that should be a bigger part of the advertising. Exposure to a wide variety of topics, many of which I had not been able to make time for up to this point was envigorating.  The list of topic includes: Office 365, Windows Server 2012, Windows 8, Metro, Azure.  I can’t wait to get back to work and dig into these subjects in more depth. The one complaint that I had and heard from other attendees was that there weren’t enough sessions that were actually about development.  I realize that TechEd started as an event for IT Pros, but there needs to be more value for the Devs.  It all went by too fast and it will take a couple more days to digest the material, but the batteries are and I’m ready to leverage what I’ve learned.  Hopefully we will do it again next year. del.icio.us Tags: TechEd,TechEd 2012

  • Installing BURG (NO MBR!)

    - by StepTNT
    I'd like to install BURG but I don't want it to overwrite my MBR. That's because I've got two bootloader in my system : 1) Default Windows 7 bl in my MBR 2) Grub in /dev/sda2 With the first power button, it will boot as Grub is not installed, so it simply loads Windows, with the second button it boots from /dev/sda2, loading Grub and then Kubuntu. Now I want to replae Grub with Burg. I've installe Burg with burg-install /dev/sda2 --force because I don't want my MBR to be overwritten (pressing the first power button MUST load Windows and avoid showing any sign of Linux things). Setup was completed without errors, and everything seems to work fine : if I open burg-manager it loads my settings, allowing me to change them and to test everything with burg-emu (that works as I want to). So, everything seems fine, Burg's installed, I've changed my settings but.. If I use the second power button, it still loads Grub! (Even a different version from the default Kubuntu one). So, here's the question : How can I replace GRUB that's on /dev/sda2 with BURG and WITHOUT writing it to my MBR? Thanks :)

  • Non-Windows, non-Unix-like OS's?

    - by dsimcha
    Since most operating systems I've heard of besides Windows seem to derive their heritage from Unix, I've been curious whether any OS's with the following characteristics exist: Not generally considered Unix-like, i.e. wasn't designed with Unix compatibility as a primary goal, doesn't use X11 as its default GUI in the most common distributions, doesn't support Unix commands by default, etc. Not in the Windows NT family. Is a modern production operating system, not a purely legacy operating system, a research/hobby project or an OS that's still in an alpha state. Is targeted at commodity x86/x64 PC hardware.

  • Varnish doesn't seem to be caching

    - by Charlie Somerville
    I've setup a Varnish cache mirror to sit in front of a file server, but it seems to be endlessly re-downloading data from my file server. There's about 100GB of data in total, but so far Varnish has downloaded 800GB from my file server. I'm using the default VCL file that comes with Varnish and the response headers for files served by the file server are similar to the following: HTTP/1.1 200 OK Cache-Control: max-age=290304000, public Content-Type: image/jpeg Expires: Wed, 29 Dec 2010 21:38:33 GMT Server: Microsoft-IIS/7.0 E-Tag: "8b4723296ab697530768f18b1378b269" Content-Disposition: inline; filename=image046.jpg; X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Thu, 23 Dec 2010 05:38:33 GMT Content-Length: 100592 I'm starting varnishd with the following options: varnish/sbin/varnishd -a 0.0.0.0:80 -f varnish/etc/varnish/default.vcl -s file,varnish/var/lib/varnish/varnish_storage.bin,100G

  • nginx can't see MySQL

    - by user135235
    I have a fully working Joomla 2.5.6 install driven by a local MySQL server, but I'd like to test nginx to see if it's a faster web serving experience than Apache. \ PHP 5.4.6 (PHP54w) \ CentOS 6.2 \ Joomla 2.5.6 \ PHP54w-fpm.i386 (FastCGI process manager) \ php -m shows: mysql & mysqli modules loaded Nginx seems to have installed fine via yum, it can process a PHP-info file via FastCGI perfectly OK (http://37.128.190.241/php.php) but when I stop Apache, start nginx instead and visit my site I get: "Database connection error (1): The MySQL adapter 'mysqli' is not available." I've tried adjusting my Joomla configuration.php to use mysql instead of mysqli but I get the same basic error, only this time "Database connection error (1): The MySQL adapter 'mysql' is not available" of course! Can anyone think what the problem might be please? I did try explicitly setting extension = mysqli.so and extension = mysql.so in my php.ini to try and force the issue (despite php -m showing they were both successfully loaded anyway) - no difference. I have a pretty standard nginx default.conf: server { listen 80; server_name www.MYDOMAIN.com; server_name_in_redirect off; access_log /var/log/nginx/localhost.access_log main; error_log /var/log/nginx/localhost.error_log info; root /var/www/html/MYROOT_DIR; index index.php index.html index.htm default.html default.htm; # Support Clean (aka Search Engine Friendly) URLs location / { try_files $uri $uri/ /index.php?q=$uri&$args; } # deny running scripts inside writable directories location ~* /(images|cache|media|logs|tmp)/.*\.(php|pl|py|jsp|asp|sh|cgi)$ { return 403; error_page 403 /403_error.html; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /etc/nginx/fastcgi.conf; } # caching of files location ~* \.(ico|pdf|flv)$ { expires 1y; } location ~* \.(js|css|png|jpg|jpeg|gif|swf|xml|txt)$ { expires 14d; } } Snip of output from phpinfo under nginx: Server API FPM/FastCGI Virtual Directory Support disabled Configuration File (php.ini) Path /etc Loaded Configuration File /etc/php.ini Scan this dir for additional .ini files /etc/php.d Additional .ini files parsed /etc/php.d/curl.ini, /etc/php.d/fileinfo.ini, /etc/php.d/json.ini, /etc/php.d/phar.ini, /etc/php.d/zip.ini Snip of output from phpinfo under Apache: Server API Apache 2.0 Handler Virtual Directory Support disabled Configuration File (php.ini) Path /etc Loaded Configuration File /etc/php.ini Scan this dir for additional .ini files /etc/php.d Additional .ini files parsed /etc/php.d/curl.ini, /etc/php.d/fileinfo.ini, /etc/php.d/json.ini, /etc/php.d/mysql.ini, /etc/php.d/mysqli.ini, /etc/php.d/pdo.ini, /etc/php.d/pdo_mysql.ini, /etc/php.d/pdo_sqlite.ini, /etc/php.d/phar.ini, /etc/php.d/sqlite3.ini, /etc/php.d/zip.ini Seems that with Apache, PHP is loading substantially more additional .ini files, including ones relating to mysql (mysql.ini, mysqli.ini, pdo_mysql.ini) than nginx. Any ideas how I get nginix to also call these additional .ini's ? Thanks in advance, Steve

  • Robocopy hiding folders on backup drives

    - by Neil Barnwell
    I have a backup batch file that uses Robocopy to backup my files: robocopy "C:\" "G:\Default\RoboCopyBackup\C" /XF Pagefile.sys /XD "System Volume Information" "Recycler" "Temporary Internet Files" "Installer Cache" "Temp" /E /R:1 /W:0 /TEE /XJ This should create a folder structure on the external backup drive like so: G:\Default\RoboCopyBackup\C\... However, G: appears totally empty. What is weird, is that the folders and files are there! If I type the above path into the address bar, I see all the files and folders! Can anyone help me work out why? I think it might be some NTFS-based ownership/permissions thing but I'm not sure.

  • Hadoop, NOSQL, and the Relational Model

    - by Phil Factor
    (Guest Editorial for the IT Pro/SysAdmin Newsletter)Whereas Relational Databases fit the world of commerce like a glove, it is useless to pretend that they are a perfect fit for all human endeavours. Although, with SQL Server, we’ve made great strides with indexing text, in processing spatial data and processing markup, there is still a problem in dealing efficiently with large volumes of ephemeral semi-structured data. Key-value stores such as Cassandra, Project Voldemort, and Riak are of great value for ephemeral data, and seem of equal value as a data-feed that provides aggregations to an RDBMS. However, the Document databases such as MongoDB and CouchDB are ideal for semi-structured data for which no fixed schema exists; analytics and logging are obvious examples. NoSQL products, such as MongoDB, tackle the semi-structured data problem with panache. MongoDB is designed with a simple document-oriented data model that scales horizontally across multiple servers. It doesn’t impose a schema, and relies on the application to enforce the data structure. This is another take on the old ‘EAV’ problem (where you don’t know in advance all the attributes of a particular entity) It uses a clever replica set design that allows automatic failover, and uses journaling for data durability. It allows indexing and ad-hoc querying. However, for SQL Server users, the obvious choice for handling semi-structured data is Apache Hadoop. There will soon be an ODBC Driver for Apache Hive .and an Add-in for Excel. Additionally, there are now two Hadoop-based connectors for SQL Server; the Apache Hadoop connector for SQL Server 2008 R2, and the SQL Server Parallel Data Warehouse (PDW) connector. We can connect to Hadoop process the semi-structured data and then store it in SQL Server. For one steeped in the culture of Relational SQL Databases, I might be expected to throw up my hands in the air in a gesture of contempt for a technology that was, judging by the overblown journalism on the subject, about to make my own profession as archaic as the Saggar makers bottom knocker (a potter’s assistant who helped the saggar maker to make the bottom of the saggar by placing clay in a metal hoop and bashing it). However, on the contrary, I find that I'm delighted with the advances made by the NoSQL databases in the past few years. Having the flow of ideas from the NoSQL providers will knock any trace of complacency out of the providers of Relational Databases and inspire them into back-fitting some features, such as horizontal scaling, with sharding and automatic failover into SQL-based RDBMSs. It will do the breed a power of good to benefit from all this lateral thinking.

  • Eclipse: open file in external editor only temporarily

    - by user54690
    Using Eclipse, I can open a Java source file with an external editor by right-clicking on the file name (in the Package Explorer) and selecting Open With ... - emacsclient. I'm very glad to be able to do that. However, I only want to do that sometimes, not every time. Now, when I double-click on that same file name, I always automatically get the file opened in emacsclient. This is particularly annoying when I use the Open Type dialog to find a file, because in that case it's not possible to right-click and choose the default Eclipse editor. Is there a way to make Eclipse forget that I previously opened a particular file with emacsclient, so that it can go back to the default behavior of using the regular Eclipse editor?

  • Ask the Readers: What Do You Have Set as Your Homepage?

    - by Mysticgeek
    When if comes to setting a homepage in your browser, it’s really based on personal preference. Today we want to know what you have set as your homepage in your favorite browser. Browser Homepage There are a lot of search sites that allow you to customize your homepage such as iGoogle, MSN, and Yahoo. Some people enjoy having a homepage set up as a dashboard of sorts. While others like simplicity and set it to Google or leave it blank. Not surprisingly in a small office or corporation you will see a lot of workstations set to MSN or the company SharePoint site. Unfortunately, a lot of free software tries to change you default homepage as well, like in this example when installing Windows Live Essentials. Make sure to avoid this by not rushing through software install wizards, and carefully opt out of such options. What is set as your homepage in your favorite web browser…both for work and at home?

  • Access - Force Form Refresh on New Record

    - by gamerzfuse
    Let me set the stage here a bit: I have an Access project with various buttons, triggers, macros, etc. I needed an Appointment Date field to only show when the button APPOINTMENT MADE is toggled ON. This works great. The problem arises when you submit a form with the APPOINTMENT MADE toggled. Once the record is inserted, the Access file clears all fields, but leaves the Appointment Date enabled, when it should be disabled by default. I have tried the Current, Load, Before Insert, After Insert and many other options on the FORM properties. Am I missing a simple way to force a refresh so the field goes back to it's default DISABLED? Thanks in advance!

  • Visual Studio 2010 Find and Replace With Regular Expressions

    - by Lance Robinson
    Here is a quick notes about using regular expressions in the VS2010 Find Replace dialog.  1.  To create a backreference, use curly braces (“{“ and “}” ) instead of regular parentheses. 2.  To use the captured backreference, use \1\2 etc, where \1 is the first captured value, \2 is the second captured value, etc. Example: I want to find*: info.setFieldValue(param1, param2); and replace it with: SetFieldValue(info, param1, param2); To do this, I can use the following find/replace values: Find what: {[a-zA-Z0-9]+}.setFieldValue\({[a-zA-Z0-9., ]+}\); Replace with: SetFieldValue(\1, \2); Use Regular Expressions is checked, of course. *If you’re wondering why I’d want to do this – because I don’t have control over the setFieldValue function – its in a third party library that doesn’t behave in a very friendly manner.

  • Augmenting functionality of subclasses without code duplication in C++

    - by Rob W
    I have to add common functionality to some classes that share the same superclass, preferably without bloating the superclass. The simplified inheritance chain looks like this: Element -> HTMLElement -> HTMLAnchorElement Element -> SVGElement -> SVGAlement The default doSomething() method on Element is no-op by default, but there are some subclasses that need an actual implementation that requires some extra overridden methods and instance members. I cannot put a full implementation of doSomething() in Element because 1) it is only relevant for some of the subclasses, 2) its implementation has a performance impact and 3) it depends on a method that could be overridden by a class in the inheritance chain between the superclass and a subclass, e.g. SVGElement in my example. Especially because of the third point, I wanted to solve the problem using a template class, as follows (it is a kind of decorator for classes): struct Element { virtual void doSomething() {} }; // T should be an instance of Element template<class T> struct AugmentedElement : public T { // doSomething is expensive and uses T virtual void doSomething() override {} // Used by doSomething virtual bool shouldDoSomething() = 0; }; class SVGElement : public Element { /* ... */ }; class SVGAElement : public AugmentedElement<SVGElement> { // some non-trivial check bool shouldDoSomething() { /* ... */ return true; } }; // Similarly for HTMLAElement and others I looked around (in the existing (huge) codebase and on the internet), but didn't find any similar code snippets, let alone an evaluation of the effectiveness and pitfalls of this approach. Is my design the right way to go, or is there a better way to add common functionality to some subclasses of a given superclass?

  • Directory error when trying to create a new user

    - by Tom Brossman
    I added a second user 'shirley' in Settings - User Accounts, and set a password. The account type is Standard. In 11.04, this worked and I logged in and had a functioning desktop for this user. How is this done in 11.10? When I try to log in as this user I have this error: Nautilus could not create the required folder "/home/shirley/.config/nautilus". Before running Nautilus, please create the following folder, or set permissions such that Nautilus can create it. The only option then is to click OK, this dumps me out to full-screen Nautilus, like this: There is no launcher or visible way to start any programs. Print screen doesn't take a screengrab. The desktop is similar to this question but I get no terminal when I press CTRL+ALT+T. I have to press CTRL+ALT+F2 and restart from the terminal to get out of this. This answer is to install gnome-system-tools. Shouldn't I be able to add a second user with the default install? EDIT: I tried the deluser+adduser suggestion, there was no change after trying it. Here is what I got: tom@desktop:~$ sudo deluser shirley [sudo] password for tom: Removing user `shirley' ... Warning: group `shirley' has no more members. Done tom@desktop:~$ sudo adduser shirley Adding user `shirley' ...

  • Are the National Computer Science Academy certifications worth it?

    - by Horacio Nuñez
    Hi to every one. I have a question regarding the real value of having NCSA's certifications. Today I reach their site and I easily passed the JavaScript certification within minutes, but I never reach questions related to Literal Javascript Notation (Json), closures or browser specific apis. This facts let me to doubt a bit of the real value of the test (and the proper certification you can have if you pay them $34), but maybe Im wrong and just earned a respected certification within the States for easy questions... in wich case I can spend some time doing other certifications on the same site. Did you have an NCSA certification and think is worth having it in your resume, or you know of a better certification program? thanks in advance, and looking forward to see your considerations.

    I have a platformer that is in progress, part of this has a camera which I only want to move when the character moves out of a certain threshold, to try to accomplish this I have the following if statement: if(((Mathf.Abs(target.transform.position.x))-(Mathf.Abs(transform.position.x)))>thres){ x = moveTo(transform.position.x, target.position.x, trackSpeed); } in unity/c#. In pseudocode it means if((absolute value of player x) - (absolute value of camera x) is greater than the threshold){ move { however this does not seem to work correctly. it appears to work for the first couple of times the threshold is reached, however the distance between the camera and the player has to increase every time for the camera to move. I do not believe the movement of the camera is the problem, however the code for it is as follows: private float moveTo(float n, float target, float accel) { if (n == target) { return n; } else { float dir = Mathf.Sign(target - n); n += accel * Time.deltaTime * dir; return (dir == Mathf.Sign(target-n))? n: target; } } }

  • Ubuntu VPN Server (PPTPD) Configuration - Pass Traffic to Internet

    - by SnAzBaZ
    I am trying to configure PPTPD on my Ubuntu box to pass all VPN traffic through to it's internet connection, so I essentially want it to work like a Proxy. I think the problem is that no default gateway is being assigned to my PPTP client (Windows 7). I can connect to the VPN fine, I get an IP address and DNS servers but no default gateway. Do I need to configure a specific option to tell the VPN server to forward all traffic it receives down it's eth0 port and out to the internet. Thanks!

  • IPv6 tunnels - any easy way to turn them on and off?

    - by Rob Hoare
    I've set up a tunnelbroker.net (Hurricane Electric) IPv6 tunnel from my laptop running 12.04. Works fine, and allows me to test the dual-stack configuration on my remote webservers etc. until native IPv6 is available on my ISP. However, there are times when I don't want the tunnel. For example if I'm accessing something that requires an IPv4 address in my own country rather than the Tunnelbroker tunnel endpoint, or if I'm away from the local IPv4 tunnel endpoint, or if I simply want to test without IPv6. Is there a simple way to disable and then re-enable the IPv6 tunnel, without rebooting? For context, here's what's in my /etc/network/interfaces (NNN replaces numbers): auto he-ipv6 iface he-ipv6 inet6 v4tunnel endpoint 216.218.NNN.NNN address 2001:470:NNN:NNN::2 netmask 64 up ip -6 route add default dev he-ipv6 down ip -6 route del default dev he-ipv6 Is there a network manager application (gui or command line) to selectively enable/disable parts of /etc/network/interfaces, or IPv6 in general? I found even by commenting out that out (and reloading networking) it's tough to get the IPv6 to go away. A "tunnel on/off" button in networking would be great, like using a VPN.

  • Unity works on my PC but not on the Server. What did I miss?

    - by Erik France
    I have a web service using Microsoft Unity to hook the pieces together.  It all works fine on my PC but when I put it on the web server, I receive this error message: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: The value of the property 'type' cannot be parsed. The error is: Method 'GetClaimsForUser' in type 'WebService.Implementation.ClaimsRetriever' from assembly 'WebService.Implementation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=62cac0f1a908971a' does not have an implementation. If I look at the web.config, I see the following: <unity>     <typeAliases>       <typeAlias alias="ITokenGenerator" type="WebService.Interfaces.ITokenGenerator, WebService.Interfaces" />       <typeAlias alias="TokenGenerator" type="WebService.Implementation.TokenGenerator, WebService.Implementation" />       <typeAlias alias="IClaimsRetriever" type="WebService.Interfaces.IClaimsRetriever, WebService.Interfaces" />       <typeAlias alias="ClaimsRetriever" type="WebService.Implementation.ClaimsRetriever, WebService.Implementation" />       <typeAlias alias="TokenGeneratorSettings" type="WebService.Implementation.TokenGeneratorSettings, WebService.Implementation" />       <typeAlias alias="String" type="System.String, mscorlib" />     </typeAliases>     <containers>       <container>         <types>           <type type="ITokenGenerator" mapTo="TokenGenerator">             <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration">               <constructor>                 <param name="retriever" parameterType="IClaimsRetriever">                   <dependency />                 </param>                 <param name="settings" parameterType="TokenGeneratorSettings">                   <dependency />                 </param>               </constructor>             </typeConfig>           </type>           <type type="IClaimsRetriever" mapTo="ClaimsRetriever">             <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration">               <constructor>                 <param name="connectionStringName" parameterType="String">                   <value value="devDatabase" type="String" />                 </param>               </constructor>             </typeConfig>           </type>         </types>       </container>     </containers>   </unity> I have another web service, using an almost identical config running on the web server.  But this new web service will not run. Any ideas on what I have not told Unity to do?  Or maybe what I told Unity to do incorrectly?

  • Configuring subdomains for a machine (Win2k8) in a lan

    - by RMS
    I am currently setting up a windows 2008 server to host a website with multiple subdomains, all accessible only within the lan. also, there is no active directory. what I did is : 1 - computer name : 'web' 2 - in IIS, I added a site binding as 'site1.web' to the default web site 3 - added DNS role to the server 4 - added 'web' as principal zone in direct lookup zones (default options) 5 - added CNAME 'site1' From a client machine, in tcpip config I added the ip address of 'web' to the DNS list in addition to the ISP DNS. (client machine ip is from DHCP) Now browsing to 'http://web' or 'http://site1.web' works correctly. My question is, is it possible throught additional steps in the server to have the websites accessible without requiring the DNS config in all the client machines ? thanks in advance

  • Creating floppy drive special devices under Quantal

    - by JCCyC
    First, I'd like for the various special devices for different floppy capacities (like /dev/fd0u720 etc.) to be available. I tried to adapt some udev rules I found online. I tried this, which I saved as /etc/udev/rules.d/70-persistent-floppy.rules: # change floppy device ownership and permissions # default permissions are 640, which prevents group users from having write access # first fix primary devices (/dev/fd0, /dev/fd1, etc.) # also change group ownership from disk to floppy SUBSYSTEM=="block", KERNEL=="fd[0-9]*", GROUP="floppy", MODE="0660" # next recreate secondary devices (/dev/fd0u720, /dev/fd0u1440, etc.) SUBSYSTEM=="block", KERNEL=="fd[0-9]*", ACTION=="add", RUN+="create_floppy_devices -c -t $attr{cmos} -m %M -M 0660 -G floppy $root/%k" But to no avail. It seems the create_floppy_devices script isn't provided with 12.10. How do I obtain it? Second: I'm using MATE, and whenever I log in I get a message box saying it tried to mount the drive but failed. How do I disable this? Third (which is probably related to the second): Whenever there's a disk in the drive, the motor won't stop spinning. If I do a mdir of it, after it returns, the motor stops, and then starts again. I suspect there's some process in MATE doing this. UPDATE: For CentOS 6 (who does have a create_floppy_devices program) the following rules file worked. Saved as /etc/udev/rules.d/98-floppy.rules: # change floppy device ownership and permissions # default permissions are 640, which prevents group users from having write access # first fix primary devices (/dev/fd0, /dev/fd1, etc.) # also change group ownership from disk to floppy KERNEL=="fd[0-9]*", GROUP="floppy", MODE="0660" # next recreate secondary devices (/dev/fd0u720, /dev/fd0u1440, etc.) # drive A: is type 4 (1.44MB) - add other lines for other drives KERNEL=="fd0*", ACTION=="add", RUN+="/lib/udev/create_floppy_devices -c -t 4 -m %M -M 0660 -G floppy $root/%k"

  • WIF, ADFS 2 and WCF&ndash;Part 1: Overview

    - by Your DisplayName here!
    A lot has been written already about passive federation and integration of WIF and ADFS 2 into web apps. The whole active/WS-Trust feature area is much less documented or covered in articles and blogs. Over the next few posts I will try to compile all relevant information about the above topics – but let’s start with an overview. ADFS 2 has a number of endpoints under the /services/trust base address that implement the WS-Trust protocol. They are grouped by the WS-Trust version they support (/13 and /2005), the client credential type (/windows*, /username*, /certificate*) and the security mode (*transport, *mixed and message). You can see the endpoints in the MMC console under the Service/Endpoints page. So in other words, you use one of these endpoints (which exactly depends on your configuration / system setup) to request tokens from ADFS 2. The bindings behind the endpoints are more or less standard WCF bindings, but with SecureConversation (establishSecurityContext) disabled. That means that whenever you need to programmatically talk to these endpoints – you can (easily) create client bindings that are compatible. Another option is to use the special bindings that come with WIF (in the Microsoft.IdentityModel.Protocols.WSTrust.Bindings namespace). They are already pre-configured to be compatible with the ADFS endpoints. The downside of these bindings is, that you can’t use them in configuration. That’s definitely a feature request of mine for the next version of WIF. The next important piece of information is the so called Federation Service Identifier. This is the value that you (at least by default) have to use as a realm/appliesTo whenever you are requesting a token for ADFS (e.g. in  IdP –> RSTS scenario). Or (even more) technically speaking, ADFS 2 checks for this value in the audience URI restriction in SAML tokens. You can get to this value by clicking the “Edit Federation Service Properties” in the MMC when the Service tree-node is selected. OK – I will come back to this basic information in the following posts. Basically I want to go through the following scenarios: ADFS in the IdP role ADFS in the R-STS role (with a chained claims provider) Using the WCF bindings for automatic token issuance Using WSTrustChannelFactory for manual token handling Stay tuned…

  • Isolated Storage Made Easy

    In its most simple form Isolated Storage allows you to save name value pairs and retrieve them at some other time the next time your app runs. Granted we could get into XML and text files etc but I'm going to stick with just name value pairs. Lets take a look at this line:private void PresistKeyValue(string _Key, string _Value){StreamWriter MyWriter = new StreamWriter(new IsolatedStorageFileStream(_Key, FileMode.Create, IsolatedStorageFile.GetUserStoreForApplication()));MyWriter.Write(_Value);MyWriter.Close();}Nice...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.
