  • The ASP.NET Daily Community Spotlight - How posts get there, and how to make it your Visual Studio Start Page

    - by Jon Galloway
    One really cool part of my job is selecting the articles for the Daily Community Spotlight, on the home page of the ASP.NET website. The spotlight highlights a new post about ASP.NET development every day from a member of the ASP.NET community. You can find it on the home page of the ASP.NET site, at http://asp.net These posts aren't automatically drawn from a pool of RSS feeds or anything - I pick a new post for each day of the year. How I pick the posts I have a few important selection criteria: Interesting to well rounded ASP.NET developers The ASP.NET website has a lot of material for all skill and experience levels, from download / get started to advanced. I try to select community spotlight posts to round that out with fresh and timely information that working ASP.NET developers can really use. Posts highlight solutions to common problems, clever projects and code that helps you leverage ASP.NET, and important announcements about things you can use today. As part of that, I try to mix between ASP.NET MVC, Web Forms, and Web Pages (a.k.a. WebMatrix). As a professional developer, I want to keep on top of all of my options for ASP.NET development, and the common platform base they all share generally means that good ASP.NET code is good ASP.NET code. Exposing new and non-Microsoft community members as much as possible The exercise of selecting good ASP.NET community posts every day of the year has made me think about what the community is. Given the choice, I'll always favor non-Microsoft employees, but since Microsoft often hires ASP.NET community members and MVP's (myself included), I really think that the ASP.NET community includes developers who are using and writing about ASP.NET, both inside and outside of Microsoft. I'm especially excited about the opportunity to highlight new and lesser known bloggers. Usually being featured on the ASP.NET Community Spotlight gives a pretty good traffic bump, and I love being able to both provide great content to the community and encourage lesser known community members by giving them some (much deserved) attention. Announcements only when they're useful to working developers - not marketing Some of the posts are announcements about new releases, such as Scott Hanselman's post on ASP.NET Universal Providers for Session, Memebership, and Roles. I include those when I think they're interesting and of immediate use to you on projects. I occasionally get asked to link to new content from a team at Microsoft; if it's useful and timely content I'll ask them to point me to a blog post by an actual person rather than a faceless team. How the posts are managed This feed used to be managed by an internal spreadsheet on a Sharepoint site, which was painful for a lot of reasons. I took a cue from Jon Udell, who uses of a public Delicious feed feed for his Elm City project, and we moved the management of these posts over to a Delicious feed as well. You can hear more about Jon's use of Delicious in Elm City in our Herding Code interview - still one of my favorite interviews. We ended up with a simpler scenario, but Note: I watched the Yahoo/Delicious news over the past year and was happy to see that Delicious was recently acquired by the founders of YouTube. I investigated several other Delicious competitors, but am happy with Delicious for now. My Delicious feed here: http://www.delicious.com/jon_galloway You can also browse through this past year's ASP.NET Community Spotlight posts using the (pretty cool) Delicious Browse Bar Submitting articles I'm always on the lookout for new articles to feature. The best way to get them to me is to share them via Delicious. It's pretty easy - sign up for an account, then you can add a post and share it to me. Alternatively, you can send them to me via Twitter (@jongalloway) or e-mail (). If you do e-mail me, it helps to include a short description and your full name so I can credit you. Way too many developer blogs don't include names and pictures; if I can't find them I can't feature the post. Subscribing to the Community Spotlight feed The Community Spotlight is available as an RSS feed, so you might want to subscribe to it: http://www.asp.net/rss/spotlight Setting the ASP.NET Community Spotlight feed as your Visual Studio start page If you're an ASP.NET developer, you might consider setting the ASP.NET Community Spotlight as the content for your Visual Studio Start Page. It's really easy - here's how to do it in Visual Studio 2010: Display the Visual Studio Start Page if it's not already showing (View / Start Page) Click on the Latest News tab and enter the following RSS URL: http://www.asp.net/rss/spotlight If you didn't previously have RSS feeds enabled for your start page, click the Enable RSS Feed button Now, every time you start up Visual Studio you'll see great content from members of the ASP.NET community: You can also configure - and disable, if you'd like - the Visual Studio start page in the Tools / Options / Environment / Startup dialog. Credits I'll do a follow-up highlighting some places I commonly find great content for the feed, but I'd like to specifically point out two of them: Elijah Manor posts a lot of great content, which is available in his Twitter feed at @elijahmanor, on his Delicious feed, and on a dedicated website - Web Dev Tweets Chris Alcock's The Morning Brew is a must-read blog which highlights each day's best blog posts across the .NET community. He's an absolute machine, and no matter how obscure the post I find, I can guarantee he'll find it as well if he hasn't already. Did I say must read?

  • Installing ikiwiki on nginx - fastcgi/fcgi wrapper

    - by meder
    My ultimate goal is to setup ikiwiki, my current goal is to get a fcgi wrapper working for nginx, so I can move on to the next step... The ikiwiki page points out this page as an example for a fcgi wrapper: http://technotes.1000lines.net/?p=23 So far I've installed the ikiwiki and libfcgi-perl modules through aptitude: aptitude install libfcgi-perl aptitude install ikiwiki It installed those packages as well as some minimal dependency packages. So the next step following the guide at technotes, I grabbed http://technotes.1000lines.net/fastcgi-wrapper.pl but I'm not sure where to actually place this file... do I run it as a service? The script makes a socket file in /var/run/nginx but that directory does not exist.. do I manually create it? So in addition to the .pl file for the cgi wrapper, I need to also define a separate cgi file for parameters. If my conf looks like this... server { listen 80; server_name notes.domain.org; access_log /www/notes/public_html/notes.domain.org/log/access.log; error_log /www/notes/public_html/notes.domain.org/log/error.log; location / { root /www/notes/public_html/notes.domain.org/public/; index index.html; } } And I don't have a cgi-bin directory, where exactly should I create it within my structure, and regarding that I'd obviously have to update the below before I include it in my conf, but I'm just not exactly sure how this would work out. # /cgi-bin configuration location ~ ^/cgi-bin/.*\.cgi$ { gzip off; fastcgi_pass unix:/var/run/nginx/perl_cgi-dispatch.sock; [1]* fastcgi_param SCRIPT_FILENAME /www/blah.com$fastcgi_script_name; [2]* include fastcgi_params; [3]* } Also since the user is www-data and /var/run is root owned, what's the proper way of giving it access? Any tips appreciated.

  • Flash/Flex/Air and iOS

    - by David Archer
    I'm just a little confused with all of the news recently regarding the cancellation of mobile flash, so was hoping for a little help. I've had a search through and can't find the answers to these questions, so any help would be great. First up, I'm looking to create a game in Flash first, to test whether the concept works as a fun game (on Newgrounds/Kongregate/Facebook etc.). Would it be best to use Flash CS5.5, or Flash Builder? Secondly, with mobile flash now being discontinued by Adobe, could I still port this game over to iOS through the Flash platform, or would it be better at that point to re-write the whole game using Objective C? (NOTE: I'm not an Objective C developer, but am instead a Javascript and Actionscript dev). Any help would be great. Thanks!

  • Where are some good resources to learn Game Development with OpenGL ES 2.X

    - by Mahbubur R Aaman
    Background: From http://www.khronos.org/opengles/2_X/ OpenGL ES 2.0 combines a version of the OpenGL Shading Language for programming vertex and fragment shaders that has been adapted for embedded platforms, together with a streamlined API from OpenGL ES 1.1 that has removed any fixed functionality that can be easily replaced by shader programs, to minimize the cost and power consumption of advanced programmable graphics subsystems. Related Resources The OpenGL ES 2.0 specification, header files, and optional extension specifications The OpenGL ES 2.0 Online Manual Pages The OpenGL ES 3.0 Shading LanguageOnline Reference Pages The OpenGL ES 2.0 Quick Reference Card OpenGL ES 1.X OpenGL ES 2.0 From http://www.cocos2d-iphone.org/archives/2003 Cocos2d Version 2 released and one of primary key point noted as OpenGL ES 2.0 support From http://www.h-online.com/open/news/item/Compiz-now-supports-OpenGL-ES-2-0-1674605.html Compiz now supports OpenGL ES 2.0 My Question : Being as a Game Developer ( I have to work with several game engine Cocos2d, Unity).

  • Chester Devs Presentation and source code &ndash; &lsquo;Event Store - an introduction to a DSD for event sourcing and notifications&rsquo;

    - by Liam Westley
    Originally posted on: http://geekswithblogs.net/twickers/archive/2013/11/11/chester-devs-presentation-and-source-code-ndash-lsquoevent-store.aspxThank you everyone at Chester Devs Thanks to Fran Hoey and all the people from Chester Devs. It was a hard drive up and back but the enthusiasm of the audience, with some great questions does make it worthwhile. Presentation and source code My presentation, source code, Event Store runners and text files containing the various command line parameters used for curl is now available on GitHub; https://github.com/westleyl/ChesterDevs-EventStore. Don’t worry if you don’t have a GitHub account, you don’t need one, you can just click on the Download Zip button on the right hand menu to download all the files as a single ZIP file.  If all you want is the PowerPoint presentation, go to https://github.com/westleyl/ChesterDevs-EventStore/blob/master/Powerpoint/Huddle-EventStore.pptx, and click on the View Raw button. Downloading and installing Event Store and Tools Download Event Store http://download.geteventstore.com – I unzipped these files into C:\EventStore\v2.0.1 Download Curl from http://curl.haxx.se/download.html – I downloaded Win64 Generic (with SSL) and unzipped these files into C:\curl version 7.31.0 Running the tools I used in my presentation Demonstration 1 (running Event Store) You can use one of my Event Store runner command files to run the single node version of Event Store, using default ports of 2213 for HTTP and 1113  for TCP, and with a wildcard HTTP pattern.  Both take a single command line parameter to specify the location of the data and log files.  The runners assume the single node executable is located in C:\EventStore\v2.0.1, and will placed data files and logs beneath C:\EventStore\Data, i.e. RunEventStore.cmd TestData1 This will create data files in C:\EventStore\Data\TestData1\Data and log files in C:\EventStore\Data\TestData1\logs. If, when running Event Store you may see the following message, [03288,15,06:23:00.622] Failed to start http server Access is denied You will either need to run Event Store in an administrator console window, or you can use the netsh command to create a firewall permission to allow HTTP listening (this will need to be run, once, in an administrator console window), netsh http add urlacl url=http://*:2213/ user=liam You can always delete this later by running the delete; netsh http delete urlacl url=http://*:2213/ If you want to confirm that everything is running OK, open the management console in a browser by navigating to http://127.0.0.1:2213. If at any point you are asked for a user name and password use the default of ‘admin’/‘changeit’. Demonstration 2 (reading and adding data, curl) In my second demonstration I used curl directly from the console to read streams, write events and then read back those events. On GitHub I have included is a set of curl commands, CurlCommandLine.txt, and a sample data file, SampleData.json, to load an event into a DDDNorth3 stream. As there is not much data in the Event Store at this point I used the $stats-127.0.0.1:2113 which is a stream containing performance statistics for Event Store and is updated every 30 seconds (default). Demonstration 3 (projections) On GitHub I have included a sample projection, Projection-ByRoom.txt, which will create streams based on the room on which a session was held on the DDDNorth3 agenda. Browse to the management console, http://127.0.0.1:2213.  Click on Projections, New Projection, give it a name, Sessions-ByRoom, and copy in the JavaScript in the Projection-ByRoom.txt file.  Select Continuous, tick Emit Enabled and then click on Post. It should run immediately. You may by challenged for the administration login for the management console, if so use the default user name and password; 'admin'/'changeit'. Demonstration 4 (C# client) The final demonstration was the Visual Studio 2012 project using the Event Store client – referenced directly as C:\EventStore\v2.0.1\EventStore.ClientAPI.dll, although you can switch this to the latest Event Store client NuGet package. The source code provides a console app for viewing projections with the projection manager (HTTP connection), as well as containing a full set of data for the entire DDDNorth3 agenda.  It also deals with the strategy for reading newest events backwards to older events and ignoring older events that have been superseded.

  • HostGator hosting account and DNS servers

    - by fxuser
    I have a hosting package on HostGator on domain example.com I also got a VPS server from Digital Ocean and have setup the DNS Details on the server there (A Record pointing on DO server IP with @ as hostname) and have also setup the DNS Servers on my domain DNS Settings which is hosted on HostGator. All seem okay right now... It's been 3-4 hours I think till I made these changes and when I point to example.com I still get on the active hosting package files instead of the server files. Do I need to cancel the hosting package first before I can make this work? EDIT: If I'm in the wrong site please move it to the correct one.

  • scorecardresearch dot com: weird tracking pixel

    - by Bobby Jack
    I'm seeing very weird behaviour in relation to this domain and a tracking image. On a specific page on our site, I'm seeing a script that's being added dynamically, apparently via flash (I wasn't even aware that flash could alter the DOM ...) That script is located at: http://scorecardresearch.com/beacon.js When I request that URL, I see a 1x1 gif. Another weird point is that this domain appears to break all the web-based whois tools; entering that domain results in a 1x1 gif. This is even to the extent where, if I enter scorecardresearch.com into the Title as part of this question, GIF code appears just below it! Hence, the "dot" in the title. The only 'unusual' thing on the page is a slideshare 'widget', which is flash-based - that's why I'm concluding that flash is altering the DOM. Anyone know what is going on here? How concerned should I be?

  • Moving from Winforms to WPF

    - by Elmex
    I am a long time experienced Windows Forms developer, but now it's time to move to WPF because a new WPF project is comming soon to me and I have only a short lead time to prepare myself to learn WPF. What is the best way for a experienced Winforms devleoper? Can you give me some hints and recommendations to learn WPF in a very short time! Are there simple sample WPF solutions and short (video) tutorials? Which books do you recommend? Is www.windowsclient.net a good starting point? Are there alternatives to the official Microsoft site? Thanks in advance for your help!

  • Having trouble redirecting frevvo using mod_proxy

    - by user38859
    This question is similar to this: http://serverfault.com/questions/102868/how-to-access-webservers-running-on-ports-blocked-on-companys-network Basically, I'm using confluence and a plugin called frevvo. Confluence sits on port 8080 while frevvo sits on port 8082. I want to redirect both of them to port 80 via Apache HTTP web server so that it doesn't get blocked by company proxies. I've been using the document on Atlassian that shows me how to run confluence behind Apache (I can't post a second URL due to being a newbie here) I've successfully redirected Confluence from port 8080 to port 80 so I can now access Confluence using www.example.com/confluence. Now I tried doing the same thing to frevvo with the following configurations: Apache httpd: ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /confluence http://localhost:8080/confluence ProxyPassReverse /confluence http://localhost:8080/confluence <Location /confluence> Order allow,deny Allow from all </Location> ProxyPass /frevvo http://localhost:8082/ ProxyPassReverse /frevvo http://localhost:8082/ <Location /forms> Order allow,deny Allow from all </Location> And in server.xml for the frevvo Tomcat instance, I added the following within <Host> tag: <Context path=" " docBase="" debug="0" reloadable="false"> <!-- Logger is deprecated in Tomcat 5.5. Logging configuration for Confluence is specified in confluence/WEB-INF/classes/log4j.properties --> <Manager pathname="" /> </Context> The plugin, frevvo, when accessed through the browser using http://localhost:8082 usually redirect to http://localhost:8082/frevvo/web With the above configuration, when accessing www.example.com.au/frevvo redirects to www.example.com/frevvo/web/static/login - which doesn't work. I hope the above details is clear and appreciate anyone who could give us some insight.

  • How to Always Load Internet Explorer 9 in Full Screen Mode

    - by Lori Kaufman
    Internet Explorer 9 has a minimal interface by default, with the tab bar and the toolbar and address bar on the same line. However, you can gain even more viewable space by pressing F11 to go to full screen mode. If you like full screen mode and want to use it most of the time, you can have Internet Explorer open in that mode automatically, by editing a setting in the registry. To begin, enter “regedit” (without the quotes) in the Search box on the Start menu. When the results display, click regedit.exe or press Enter when it’s highlighted. NOTE: Before making changes to the registry, be sure you back it up. We also recommend creating a restore point you can use to restore your system if something goes wrong.

  • .htaccess Permission denied. Unable to check htaccess file

    - by Josh
    I have a strange problem when adding a sub-domain to our virtual server. I have done similar sub-domains before and they have worked fine. When I try to access the sub-domain I get an 403 Forbidden error. I checked the error logs and have the following error: pcfg_openfile: unable to check htaccess file, ensure it is readable I've searched Google and could only find solutions regarding file and folder permissions, that I have checked and the solution isn't solved. I also saw problems with Frontpage Extensions, but that's not installed on the server. Edit Forgot to say that there isn't a .htaccess file in the directory of the sub-domain Edit #2 Still not been able to find a solution on this. Only things I have been able to find out is: It doesn't seem to be a problem with any .htaccess files (I've tried creating blank ones, with correct user privileges). It doesn't seem to be a problem with any folder permissions as they are all set correct. There isn't a problem with the way the sub-domain has been set up, as I've tried pointing the DocumentRoot to another folder and it worked fine. I've also done sub-domains fine before with no problem. Edit #3 Find out more information. I don't think it can be a file permission problem now, because if I access it by going to the server ip and then the directory where the site is hosted it all works fine (minus the stylesheets & images, which is just down to how they are linked)

  • Installation Won't Finish

    - by Joey G
    I installed Ubuntu 12.10 (32-bit) on my Acer Aspire One notebook and replaced the Windows 8 Consumer Preview. Everything went fine, but right before the installation finished, it got stuck. The loading bar at the bottom is full, and it says "Copying installation logs," but my mouse won't move and it's been at this point for almost an hour. Also, the mouse is in the loading spin, so I know my computer didn't freeze. Should I just restart now? I'm not sure if it's at the last stage, but it seems like it is, and this has taken more than the rest of the installation together. EDIT- I had my computer go in sleep mode for a minute and now I can move the mouse again. When I click the "Copying.." part, it says "Activation (eth1) Stage 4 of 5 complete" but "5 of 5" (I assume that comes next) isn't starting.

  • Request Limit Length Limits for IIS&rsquo;s requestFiltering Module

    - by Rick Strahl
    Today I updated my CodePaste.net site to MVC 3 and pushed an update to the site. The update of MVC went pretty smooth as well as most of the update process to the live site. Short of missing a web.config change in the /views folder that caused blank pages on the server, the process was relatively painless. However, one issue that kicked my ass for about an hour – and not foe the first time – was a problem with my OpenId authentication using DotNetOpenAuth. I tested the site operation fairly extensively locally and everything worked no problem, but on the server the OpenId returns resulted in a 404 response from IIS for a nice friendly OpenId return URL like this: http://codepaste.net/Account/OpenIdLogon?dnoa.userSuppliedIdentifier=http%3A%2F%2Frstrahl.myopenid.com%2F&dnoa.return_to_sig_handle=%7B634239223364590000%7D%7BjbHzkg%3D%3D%7D&dnoa.return_to_sig=7%2BcGhp7UUkcV2B8W29ibIDnZuoGoqzyS%2F%2FbF%2FhhYscgWzjg%2BB%2Fj10ZpNdBkUCu86dkTL6f4OK2zY5qHhCnJ2Dw%3D%3D&openid.assoc_handle=%7BHMAC-SHA256%7D%7B4cca49b2%7D%7BMVGByQ%3D%3D%7D&openid.claimed_id=http%3A%2F%2Frstrahl.myopenid.com%2F&openid.identity=http%3A%2F%2Frstrahl.myopenid.com%2F&openid.mode=id_res&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1&openid.op_endpoint=http%3A%2F%2Fwww.myopenid.com%2Fserver&openid.response_nonce=2010-10-29T04%3A12%3A53Zn5F4r5&openid.return_to=http%3A%2F%2Fcodepaste.net%2FAccount%2FOpenIdLogon%3Fdnoa.userSuppliedIdentifier%3Dhttp%253A%252F%252Frstrahl.myopenid.com%252F%26dnoa.return_to_sig_handle%3D%257B634239223364590000%257D%257BjbHzkg%253D%253D%257D%26dnoa.return_to_sig%3D7%252BcGhp7UUkcV2B8W29ibIDnZuoGoqzyS%252F%252FbF%252FhhYscgWzjg%252BB%252Fj10ZpNdBkUCu86dkTL6f4OK2zY5qHhCnJ2Dw%253D%253D&openid.sig=h1GCSBTDAn1on98sLA6cti%2Bj1M6RffNerdVEI80mnYE%3D&openid.signed=assoc_handle%2Cclaimed_id%2Cidentity%2Cmode%2Cns%2Cns.sreg%2Cop_endpoint%2Cresponse_nonce%2Creturn_to%2Csigned%2Csreg.email%2Csreg.fullname&openid.sreg.email=rstrahl%40host.com&openid.sreg.fullname=Rick+Strahl A 404 of course isn’t terribly helpful – normally a 404 is a resource not found error, but the resource is definitely there. So how the heck do you figure out what’s wrong? If you’re just interested in the solution, here’s the short version: IIS by default allows only for a 1024 byte query string, which is obviously exceeded by the above. The setting is controlled by the RequestFiltering module in IIS 6 and later which can be configured in ApplicationHost.config (in \%windir\system32\inetsvr\config). To set the value configure the requestLimits key like so: <configuration> <security> <requestFiltering> <requestLimits maxQueryString="2048"> </requestLimits> </requestFiltering> </security> </configuration> This fixed me right up and made the requests work. How do you find out about problems like this? Ah yes the troubles of an administrator? Read on and I’ll take you through a quick review of how I tracked this down. Finding the Problem The issue with the error returned is that IIS returns a 404 Resource not found error and doesn’t provide much information about it. If you’re lucky enough to be able to run your site from the localhost IIS is actually very helpful and gives you the right information immediately in a nicely detailed error page. The bottom of the page actually describes exactly what needs to be fixed. One problem with this easy way to find an error: You HAVE TO run localhost. On my server which has about 10 domains running localhost doesn’t point at the particular site I had problems with so I didn’t get the luxury of this nice error page. Using Failed Request Tracing to retrieve Error Info The first place I go with IIS errors is to turn on Failed Request Tracing in IIS to get more error information. If you have access to the server to make a configuration change you can enable Failed Request Tracing like this: Find the Failed Request Tracing Rules in the IIS Service Manager.   Select the option and then Edit Site Tracing to enable tracing. Then add a rule for * (all content) and specify status codes from 100-999 to capture all errors. if you know exactly what error you’re looking for it might help to specify it exactly to keep the number of errors down. Then run your request and let it fail. IIS will throw error log files into a folder like this C:\inetpub\logs\FailedReqLogFiles\W3SVC5 where the last 5 is the instance ID of the site. These files are XML but they include an XSL stylesheet that provides some decent formatting. In this case it pointed me straight at the offending module:   Ok, it’s the RequestFilteringModule. Request Filtering is built into IIS 6-7 and configured in ApplicationHost.config. This module defines a few basic rules about what paths and extensions are allowed in requests and among other things how long a query string is allowed to be. Most of these settings are pretty sensible but the query string value can easily become a problem especially if you’re dealing with OpenId since these return URLs are quite extensive. Debugging failed requests is never fun, but IIS 6 and forward at least provides us the tools that can help us point in the right direction. The error message the FRT report isn’t as nice as the IIS error message but it at least points at the offending module which gave me the clue I needed to look at request restrictions in ApplicationHost.config. This would still be a stretch if you’re not intimately familiar, but I think with some Google searches it would be easy to track this down with a few tries… Hope this was useful to some of you. Useful to me to put this out as a reminder – I’ve run into this issue before myself and totally forgot. Next time I got it, right?© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET  Security

  • Windows 8 and SMB2 Issues

    - by Rhys Paterson
    We're playing with the consumer preview of Windows 8 and having issues accessing some network shares in our environment. Basically, when I attempt to access a share directly (\[SERVER].[DOMAIN].[NETWORK]\Share$) I get 'An extended error has occured'. The shares reside on an EMC Celerra system. Sorry, I don't really have much more information about it (this is just a little side project). Accessing shares that reside on Windows machines are fine. The Firewall is completley disabled and I am running under full domain administrative credentials. A quick wireshark shows the following group of packets between myself and the server: SMB2 164 NegotiateProtocol Request SMB2 274 NegotiateProtocol Response SMB2 981 SessionSetup Request SMB2 281 SessionSetup Response SMB2 200 TreeConnect Request Tree: \\[SERVER].[DOMAIN].[NETWORK]\[SHARE]$ SMB2 138 TreeConnect Response SMB2 202 Ioctl Request NETWORK_FILE_SYSTEM Function:0x0080 SMB2 131 Ioctl Response, Error: STATUS_INVALID_DEVICE_REQUEST SMB2 126 SessionLogoff Request SMB2 126 SessionLogoff Respons This repeats five times and then (I assume) Windows throws me the above error. A quick Google shows me: 0xC0000010 STATUS_INVALID_DEVICE_REQUEST The specified request is not a valid operation for the target device. Which shows me that NETWORK_FILE_SYSTEM Function:0x0080 request is invalid.. Does anyone know what would cause this? Thanks in advance. Rhys. Edit: FYI - as a workaround, you can disable SMB 2.2 as noted in the EMC thread: sc config lanmanworkstation depend= bowser/mrxsmb10/nsi sc config mrxsmb20 start= disabled This will allow the machine to access the shares. The below answer still stands though :)

  • Getting SMB file shares working over a PPTP VPN

    - by Ben Scott
    I'm having issues getting SMB file shares working over a PPTP VPN. The server setup consists of a security device (DrayTek V3300) which passes the PPTP authentication to a SBS2003 server running RRAS. The server is the DC and provides DNS and WINS, the single NIC's name server is set to the NIC's IP (192.168...), and DHCP on the DrayTek sets the server IP as the DNS. If I create a new VPN connection in Win7, leaving everything as default apart from the server, username, password and domain, I can: ping everything by IP address resolve IPs with nslookup using their fully-qualified name, as in nslookup fileserver.mydomain.local ping machines by fully-qualified name, as in ping fileserver.mydomain.local However if I try to access a file share: within Explorer, I get "Windows cannot access ..." with "Error code: 0x80004005 Unspecified Error", using net use z: \\fileserver.mydomain.local\share, I get "System error 53 has occurred. The network path was not found." If I add the machine name to my HOSTS file I can use the file share, which is my last-ditch workaround, but I have a number of VPN users and would rather a solution that doesn't involve me trying to hand-edit system files on computers half a country away. If I set the WINS server explicitly in the connection's IPv4 settings I don't have to use the FQN to ping the machine, but that doesn't change anything else. EDIT: The PC I'm having the issue on is running Win 7 Home Premium. After more testing I actually have two other PCs that work, one W7HP, one XP Home, and another Vista PC that doesn't work (not tested as much as the others), all four on the same internet connection (behind the same router). All of them were tested with a straight-forward, all defaults, new VPN configuration.

  • Launching firefox on remote server causes local firefox to start instead

    - by terdon
    Right, this is strange. I am connecting from my laptop (LMDE) to a remote host (SUSE linux enterprise) using ssh -X. I want to launch a firefox instance running on the remote server so I can have access to webpages on a private network. User@RemoteMachine $ which -a firefox /usr/bin/firefox User@RemoteMachine $ /usr/bin/firefox --version Mozilla Firefox 2.0.0.2, Copyright (c) 1998 - 2007 mozilla.org User@LocalMachine $ which -a firefox /usr/bin/firefox User@LocalMachine $ /usr/bin/firefox --version Mozilla Firefox 14.0.1 Now, if firefox is not running on the local machine, everything goes as expected and executing firefox on the remote machine causes a firefox (v 2.0) window running on the remote machine to show up. However, if firefox is running on the local machine a second window of firefox 14.0.1 running on the local machine appears. I have checked top in both machines. In the 2nd case, a firefox process briefely appears on the remote machine and then disappears when the local version of firefox is launched. My questions are the following: What gives? How/why can firefox connect to its existing instance on the local machine? The remote machine appears to have access to the local machine. It, in fact, appears to have the right to execute programs on my local machine. Am I missing something or is this just weird? Is this not a security risk?

  • Lync CMS replication is failing for all Domain Computers

    - by Ravi Kanneganti
    I have Lync Server 2010 and Active Directory installed on 2 different Windows Server 2008 R2 machines. I have added a Windows 7 PC to AD. And I have added this computer to Trusted Application Servers Pool and published the topology. I want to build an UCMA application to extend Lync Server functionality.

  • The Presentation Secrets of Steve Jobs

    - by guybarrette
    A few years go, I got interested in presentation styles after reading Cliff Atkinson’s Beyond Bullet Points book.  At that time, it was obvious that the Microsoft presentation culture was kind of missing the point by having far too many bullet points. I recently picked up Carmine Gallo’s The Presentation Secrets of Steve Jobs.  I enjoyed this short read (238 pages) book full of presentation tips.  The best advise that I got from reading this book is that you must have an antagonist in your presentation.  This will help the audience visualize and understand the problem (antagonist) and the solution (what you present).  When presenting a technical topic, it is easy to forget to explain what problem is being solved by using this new technology/technique/pattern/API. This is a great read for anyone giving presentations, technical or not.     var addthis_pub="guybarrette";

  • Adopting DBVCS

    - by Wes McClure
    Identify early adopters Pick a small project with a small(ish) team.  This can be a legacy application or a green-field application. Strive to find a team of early adopters that will be eager to try something new. Get the team on board! Research Research the tool(s) that you want to use.  Some tools provide all of the features you would need while some only provide a slice of the pie.  DBVCS requires the ability to manage a set of change scripts that update a database from one version to the next.  Ideally a tool can track database versions and automatically apply updates.  The change script generation process can be manual, but having diff tools available to automatically generate it can really reduce the overhead to adoption.  Finally, an automated tool to generate a script file per database object is an added bonus as your version control system can quickly identify what was changed in a commit (add/del/modify), just like with code changes. Don’t settle on just one tool, identify several.  Then work with the team to evaluate the tools.  Have the team do some tests of the following scenarios with each tool: Baseline an existing database: can the migration tool work with legacy databases?  Caution: most migration platforms do not support baselines or have poor support, especially the fad of fluent APIs. Add/drop tables Add/drop procedures/functions/views Alter tables (rename columns, add columns, remove columns) Massage data – migrations sometimes involve changing data types that cannot be implicitly casted and require you to decide how the data is explicitly cast to the new type.  This is a requirement for a migrations platform.  Think about a case where you might want to combine fields, or move a field from one table to another, you wouldn’t want to lose the data. Run the tool via the command line.  If you cannot automate the tool in Continuous Integration what is the point? Create a copy of a database on demand. Backup/restore databases locally. Let the team give feedback and decide together, what tool they would like to try out. My recommendation at this point would be to include TSqlMigrations and RoundHouse as SQL based migration platforms.  In general I would recommend staying away from the fluent platforms as they often lack baseline capabilities and add overhead to learn a new API when SQL is already a very well known DSL.  Code migrations often get messy with procedures/views/functions as these have to be created with SQL and aren’t cross platform anyways.  IMO stick to SQL based migrations. Reconciling Production If your project is a legacy application, you will need to reconcile the current state of production with your development databases.  Find changes in production and bring them down to development, even if they are old and need to be removed.  Once complete, produce a baseline of either dev or prod as they are now in sync.  Commit this to your VCS of choice. Add whatever schema changes tracking mechanism your tool requires to your development database.  This often requires adding a table to track the schema version of that database.  Your tool should support doing this for you.  You can add this table to production when you do your next release. Script out any changes currently in dev.  Remove production artifacts that you brought down during reconciliation.  Add change scripts for any outstanding changes in dev since the last production release.  Commit these to your repository.   Say No to Shared Dev DBs Simply put, you wouldn’t dream of sharing a code checkout, why would you share a development database?  If you have a shared dev database, back it up, distribute the backups and take the shared version offline (including the dev db server once all projects are using DB VCS).  Doing DB VCS with a shared database is bound to cause problems as people won’t be able to easily script out their own changes from those that others are working on.   First prod release Copy prod to your beta/testing environment.  Add the schema changes table (or mechanism) and do a test run of your changes.  If successful you can schedule this to be run on production.   Evaluation After your first release, evaluate the pain points of the process.  Try to find tools or modifications to existing tools to help fix them.  Don’t leave stones unturned, iteratively evolve your tools and practices to make the process as seamless as possible.  This is why I suggest open source alternatives.  Nothing is set in stone, a good example was adding transactional support to TSqlMigrations.  We ran into situations where an update would break a database, so I added a feature to do transactional updates and rollback on errors!  Another good example is generating change scripts.  We have been manually making these for months now.  I found an open source project called Open DB Diff and integrated this with TSqlMigrations.  These were things we just accepted at the time when we began adopting our tool set.  Once we became comfortable with the base functionality, it was time to start automating more of the process.  Just like anything else with development, never be afraid to try to find tools to make your job easier!   Enjoy -Wes

  • Great library of ASP.NET videos – Pluralsight!

    - by hajan
    I have been subscribed to the Pluralsight website and of course since ASP.NET is my favorite development technology, I passed throughout few series of videos related to ASP.NET. You have list of ASP.NET galleries from Fundamentals to Advanced topics including the latest features of ASP.NET 4.0, ASP.NET Ajax, ASP.NET MVC etc. Most of the speakers are either Microsoft MVPs or known technology experts! I was really curious to see the way they have organized the entire course materials, and trust me, I was quite amazed. I saw the ASP.NET 4.0 video series to confirm my knowledge and some other video series regarding general software development concepts, design patterns etc. I would like to point out if anyone of you is interested to get FREE 1-week .NET training pass in the Pluralsight library, please CONTACT ME, write your name and email and include the purpose of the message in the content. I hope you will find this useful. Regards, Hajan
