• make IIS 7.5 cache static content files over diferent pages

  - by Achilles

  On a Windows 2008 R2, using DNS and IIS I've established my development test server; i.e. I'll have a web application that I can browse on http://test.dev I've moved all the static content files like images, js files and css files into another application which is visible on http://cdn.test.dev test.dev, uses cdn.test.dev urls like http://cdn.test.dev/js/jquery.js to load js, css and images. When I first load "~/" of test.dev, all files will load with a response code of 200; when I press F5 in Firefox, all files, except the "~/default.aspx", will load with 304 response code; but pressing Ctrl+F5 loads them again with a 200 code; if I browse another url like "~/pages/" in test.dev, all of those static files will reload with a 200 code... Is this normal or I'm doing something wrong? Actually, I'm looking for a behavior like this: I want the client to load http://cdn.test.dev/js/jquery.js, only once. I want the client's browser to use this jquery.js file, from cache, in all other pages of test.dev Is this possible? This is the web.config file I have in the root directory of cdn.test.dev: <configuration> <system.webServer> <caching> <profiles> <add extension=".png" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".gif" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".jpg" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".js" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".css" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".axd" kernelCachePolicy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> </profiles> </caching> <httpProtocol allowKeepAlive="true"> <customHeaders> <add name="Cache-Control" value="public, max-age=31536000" /> </customHeaders> </httpProtocol> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true"> <remove name="RadUploadModule" /> <remove name="RadCompression" /> <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" preCondition="integratedMode" /> <add name="RadCompression" type="Telerik.Web.UI.RadCompression" preCondition="integratedMode" /> </modules> <handlers> <remove name="ChartImage_axd" /> <remove name="Telerik_Web_UI_SpellCheckHandler_axd" /> <remove name="Telerik_Web_UI_DialogHandler_aspx" /> <remove name="Telerik_RadUploadProgressHandler_ashx" /> <remove name="Telerik_Web_UI_WebResource_axd" /> <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode" /> </handlers> <security> <requestFiltering> <requestLimits maxAllowedContentLength="10485760" /> </requestFiltering> </security> <staticContent> <clientCache cacheControlMode="UseExpires" httpExpires="Wed, 01 Jan 2020 00:00:00 GMT"/> </staticContent> </system.webServer> <appSettings /> <system.web> <compilation debug="false" targetFramework="4.0" /> <pages> <controls> <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI" /> </controls> </pages> <httpHandlers> <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" /> <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" /> </httpHandlers> <httpModules> <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" /> <add name="RadCompression" type="Telerik.Web.UI.RadCompression" /> </httpModules> <httpRuntime maxRequestLength="10240" /> </system.web> </configuration> and this is the resulting response header for http://cdn.test.dev/css/global.css: Cache-Control: private,public, max-age=31536000 Content-Type: text/css Content-Encoding: gzip Expires: Wed, 01 Jan 2020 00:00:00 GMT Last-Modified: Mon, 06 Sep 2010 08:53:06 GMT Accept-Ranges: bytes Etag: "0454eca04dcb1:0" Vary: Accept-Encoding Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Mon, 06 Sep 2010 14:57:08 GMT Content-Length: 4495

• VNC client not working -- Not able to see the changes happening on the other side

  - by javanoob

  Here is the Problem: I have two computers connected in the same LAN. I am trying to access one computer from another using Remote Desktop Viewer, I am able to see the remote desktop. But when i click on any thing or perform any action, I dont see the result but the action is performed on the remote desktop..But it is not refreshed on the remote desktop screen.. For Ex: 1) Opened Remote Desktop viewer 2) Connected to the other computer which has yahoo home page opened 3) Clicked on the close button of the web page 4) Action is performed on the other computer (Yahoo page is closed). 5) On Remote Desktop screen i still see the Yahoo home page 6) Whatever action i perform on remote desktop screen i see the same screen(In this case yahoo home page) Bottom line: Whatever screen i see on the start up of Remote Desktop viewer that is not getting refreshed. So the thing is though i am able to perform actions on remote desktop, the screen is not refreshing.. How do i solve this? I hope i made my point clear.. NOTE: I am connecting to Ubuntu 9.04 machine from Ubuntu 10.04LTS.. I am really not sure if that makes any difference.

• LDAP change user pass on client

  - by Sean

  I am trying to allow ldap users to change their password on client machines. I have tried pam every which way I can think of /etc/ldap.conf & /etc/pam_ldap.conf, as well. At this point I'm stuck. Client: Ubuntu 11.04 Server: Debian 6.0 The current output is this: sobrien4@T-E700F-1:~$ passwd passwd: Authentication service cannot retrieve authentication info passwd: password unchanged /var/log/auth.log gives this during the command: May 9 10:49:06 T-E700F-1 passwd[18515]: pam_unix(passwd:chauthtok): user "sobrien4" does not exist in /etc/passwd May 9 10:49:06 T-E700F-1 passwd[18515]: pam_ldap: ldap_simple_bind Can't contact LDAP server May 9 10:49:06 T-E700F-1 passwd[18515]: pam_ldap: reconnecting to LDAP server... May 9 10:49:06 T-E700F-1 passwd[18515]: pam_ldap: ldap_simple_bind Can't contact LDAP server getent passwd |grep sobrien4 (note keeping short since testing with that account, however it outputs all ldap users): sobrien4:Ffm1oHzwnLz0U:10000:12001:Sean O'Brien:/home/sobrien4:/bin/bash getent group shows all ldap groups. /etc/pam.d/common-password (Note this is just the most current, I have tried a lot of different options): password required pam_cracklib.so retry=3 minlen=8 difok=3 password [success=1 default=ignore] pam_unix.so use_authtok md5 password required pam_ldap.so use_authtok password required pam_permit.so Popped open wireshark as well, the server & client are talking. I have the password changing working on the server. I.E. the server that runs slapd, I can log in with the ldap user and change the passwords. I tried copying the working configs from the server initially and no dice. I also tried cloning it, and just changing ip & host, and no go. My guess is that the client is not authorized by ip or hostname to change a pass. Pertaining to the slapd conf, I saw this in a guide and tried it: access to attrs=loginShell,gecos by dn="cn=admin,dc=cengineering,dc=etb" write by self write by * read access to * by dn="cn=admin,dc=cengineering,dc=etb" write by self write by * read So ldap seems to be working okay, just can't change the password.

• SRs @ Oracle: How do I License Thee?

  - by [email protected]

  With the release of the new Sun Ray product last week comes the advent of a different software licensing model. Where Sun had initially taken the approach of '1 desktop device = one license', we later changed things to be '1 concurrent connection to the server software = one license', and while there were ways to tell how many connections there were at a time, it wasn't the easiest thing to do.  And, when should you measure concurrency?  At your busiest time, of course... but when might that be?  9:00 Monday morning this week might yield a different result than 9:00 Monday morning last week.In the acquisition of this desktop virtualization product suite Oracle has changed things to be, in typical Oracle fashion, simpler.  There are now two choices for customers around licensing: Named User licenses and Per Device licenses.Here's how they work, and some examples:The Rules1) A Sun Ray device, and PC running the Desktop Access Client (DAC), are both considered unique devices.OR, 2) Any user running a session on either a Sun Ray or an DAC is still just one user.So, you have a choice of path to go down.Some Examples:Here are 6 use cases I can think of right now that will help you choose the Oracle server software licensing model that is right for your business:Case 1If I have 100 Sun Rays for 100 users, and 20 of them use DAC at home that is 100 user licenses.If I have 100 Sun Rays for 100 users, and 20 of them use DAC at home that is 120 device licenses.Two cases using the same metrics - different licensing models and therefore different results.Case 2If I have 100 Sun Rays for 200 users, and 20 of them use DAC at home that is 200 user licenses.If I have 100 Sun Rays for 200 users, and 20 of them use DAC at home that is 120 device licenses.Same metrics - very different results.Case 3If I have 100 Sun Rays for 50 users, and 20 of them use DAC at home that is 50 user licenses.If I have 100 Sun Rays for 50 users, and 20 of them use DAC at home that is 120 device licenses.Same metrics - but again - very different results.Based on the way your business operates you should be able to see which of the two licensing models is most advantageous to you.Got questions?  I'll try to help.(Thanks to Brad Lackey for the clarifications!)

• Using Cisco VPN in Windows 7 XP Mode?

  - by Shane

  I previously asked a question about whether it was possible to use Cisco VPN client on Windows 7 64-bit (see below). Now that I have it set up, it doesn't work when I try to connect off the local network. I realize that there must be some networking/routing that I need to do since it's running on a virtual machine. How does one go about using the Cisco VPN client from XP mode in Windows 7? Related: Cisco VPN Client on Windows 7 64-bit?

• teamviewer in "client only" mode

  - by Tommy

  I have a remote PC with the teamviewer on it. I want to use my local teamviewer installation only for connecting to that remote PC, and I don't want any services (teamviewerd) running on my local Ubuntu 14.04. I've tried to disable the service by doing sudo teamviewer --daemon disable but after that I'm not able to connect to the remote PC, because teamviewer reports an error "The Teamviewer daemon is not running!" on start, and I'm not able to access the gui. Is there a way to connect to the remote PC with teamviewer with no teamviewerd running?

• Cloud Computing Architecture Patterns: Don’t Focus on the Client

  - by BuckWoody

  Normally I try to put topics in the positive in other words "Do this" not "Don't do that". Sometimes its clearer to focus on what *not* to do. Popular development processes often start with screen mockups, or user input descriptions. In a scale-out pattern like Cloud Computing on Windows Azure, that's the wrong place to start. Start with the Data    Instead, I recommend that you start with the data that a process requires. That data might be temporary or persisted, but starting with the data and its requirements helps to define not only the storage engine you need but also drives everything from security to the integrity of the application. For instance, assume the requirements show that the user must enter their phone number, and that this datum is used in a contact management system further down the application chain. For that datum, you can determine what data type you need (U.S. only or International?) the security requirements, whether it needs ACID compliance, how it will be searched, indexed and so on. From one small data point you can extrapolate out your options for storing and processing the data. Here's the interesting part, which begins to break the patterns that we've used for decades: all of the data doesn't have the same requirements. The phone number might be best suited for a list, or an element, or a string, with either BASE or ACID requirements, based on how it is used. That means we don't have to dump everything into XML, an RDBMS, a NoSQL engine, or a flat file exclusively. In fact, one record might use all of those depending on the use-case requirements. Next Is Data Management  With the data defined, we can move on to how to store the data. Again, the requirements now dictate whether we need a full relational calculus or set-based operations, or we can choose another method based on the requirements for the data. And breaking another pattern its OK to store in more than once, in more than one location. We do this all the time for reporting systems and Business Intelligence systems, so this is a pattern we need to think about even for OLTP data. Move to Data Transport How does the data get around? We can use a connection-based method, sending the data along a transport to the storage engine, but in some cases we may want to use a cache, a queue, the Service Bus, or Complex Event Processing. Finally, Data Processing Most RDBMS engines, NoSQL, and certainly Big Data engines not only store data, but can process and manipulate it as well. Its doubtful that you'll calculate that phone number right? Well, if you're the phone company, you most certainly will. And so we see that even once we've chosen the data type, storage and engine, the same element can have different computing requirements based on how it is used. Sure, We Need A Front-End At Some Point Not all data is entered by human hands in fact most data isn't. We don't really need a Graphical User Interface (GUI) we need some way for a GUI to get data into and out of the systems listed earlier.   But when we do need to allow users to enter or examine data, that should be left to the GUI that best fits the device the user has. Ever tried to use an application designed for a web browser on a phone? Or one designed for a tablet on a phone? Its usually quite painful. The siren song of "We'll just write one interface for all devices" is strong, and has beguiled many an unsuspecting architect. But they just don't work out.   Instead, focus on the data, its transport and processing. Create API calls or a message system that allows for resilient transport to the device or interface, and let it do what it does best.

• Group Policy GPO not 'seen' at client

  - by fukawi2

  I have a new OU (natorg.local\NATO\Users) that I am trying to apply GP to. I have created a new user in this OU, and linked the 3 GPO's to this OU: DESKTOP - Folder Redirection (AppData) DESKTOP - Folder Redirection (Desktop) DESKTOP - Folder Redirection (Documents) Hopefully the names are sufficient to suggest what they do exactly. The settings are under User Settings so there is no Loopback processing required (if my understanding is correct). GP Modelling for the user and specific computer says that the GPOs will/should be applied, however on the client, gpresult doesn't even appear to see the GPOs under either "Applied" or "Not Applied": USER SETTINGS -------------- CN=Amir,OU=Users,OU=NATO,DC=natorg,DC=local Last time Group Policy was applied: 25/06/2012 at 11:07:13 AM Group Policy was applied from: svr-addc-01.natorg.local Group Policy slow link threshold: 500 kbps Applied Group Policy Objects ----------------------------- LAPTOPS - Power Settings WSUS - Set Server Address OUTLOOK - Auto Archive SECURITY - Lock Screen After Idle Default Domain Policy DESKTOP - Regional Settings NETWORK - Proxy Configuration NETWORK - IE General Config OFFICE - Trusted Locations OFFICE - Increase Privacy OUTLOOK - Disable Junk Filter DESKTOP - Disable Windows Error Reporting DESKTOP - Hide Language Bar NETWORK - Disable Skype DESKTOP - Disable Thumbs.db Creation WSUS - Set Server Address The following GPOs were not applied because they were filtered out ------------------------------------------------------------------- Local Group Policy Filtering: Not Applied (Empty) NETWORK - Google Chrome Configuration Filtering: Not Applied (Empty) SYSTEM - Event Log Configuration Filtering: Not Applied (Empty) SECURITY - Local Administrator Password Filtering: Not Applied (Empty) NETWORK - Disable Windows Messenger Filtering: Not Applied (Empty) SECURITY - Audit Policy Filtering: Not Applied (Empty) WSUS - Automatic Install Filtering: Not Applied (Empty) NETWORK - Firewall Configuration Filtering: Not Applied (Empty) DESKTOP - Enable Offline Files Filtering: Not Applied (Empty) I haven't altered permissions on the GPO's at all, no WMI filtering... As I said, GP Modelling says that they should be applied. GPResult on the client correctly identifies itself as being the correct OU (CN=Amir,OU=Users,OU=NATO,DC=natorg,DC=local) There are 2 x 2008R2 and a 2003 DC, domain is 2003 level, client is Windows XP SP3. Can anyone suggest why these GP Objects would be "invisible" to the client?

  I had a question posed to me the other day by another programmer. I remember (a very long time ago) wondering the very same. Why was a browser-side include tag never considered? Or was it? Specifically with a tag that instructed the browser to include additional HTML from other sources. e.g. <include src="http://server/foo/bar.html">. Many folks will make javascript calls and fill innerHTML to accomplish the same, when the same outside a the javascript engine could be accomplished by the browser. It would have been painful to have nested <HTML>s <BODY>s (i.e.) but we have to consider that aspect anywhere anyway.

• Route all traffic via OpenVPN client

  - by Ilya

  I've got OpenVPN client running on 192.168.0.3. What I'd like to do is route all the traffic from the second computer with 192.168.0.100 via OpenVPN client that's running on the first computer. My router ip is 192.168.0.1 Network topology: Windows computer with OpenVPN client: 192.168.0.3 Windows computer whose traffic has to be rerouted: 192.168.0.100 Router: 192.168.0.1 I want it to work in the following way: 192.168.0.100 computer => 192.168.0.3 computer => OpenVPN => 192.168.0.1 How can I achieve that by only modifying windows' routing table? I've tried entering the following into windows shell(on computer without VPN), which didn't work (it just dropped my internet connection): route delete 0.0.0.0 mask 255.255.255.255 192.168.0.1 route add 0.0.0.0 mask 255.255.255.255 192.168.0.3 Should I also setup the computer that has OpenVPN client running? Does it have anything to do with windows tcp forwarding? Thanks!

• Game development: “Play Now” via website vs. download & install

  - by Inside

  Heyo, I've spent some time looking over the various threads here on gamedev and also on the regular stackoverflow and while I saw a lot of posts and threads regarding various engines that could be used in game development, I haven't seen very much discussion regarding the various platforms that they can be used on. In particular, I'm talking about browser games vs. desktop games. I want to develop a simple 3D networked multiplayer game - roughly on the graphics level of Paper Mario and gameplay with roughly the same level of interaction as a hack & slash action/adventure game - and I'm having a hard time deciding what platform I want to target with it. I have some experience with using C++/Ogre3D and Python/Panda3D (and also some synchronized/networked programming), but I'm wondering if it's worth it to spend the extra time to learn another language and another engine/toolkit just so that the game can be played in a browser window (I'm looking at jMonkeyEngine right now). For simple & short games the newgrounds approach (go to the site, click "play now", instant gratification) seems to work well. What about for more complex games? Is there a point where the complexity of a game is enough for people to say "ok, I'm going to download and play that"? Is it worth it to go with engines that are less-mature, have less documentation, have fewer features, and smaller communities* just so that a (possibly?) larger audience can be reached? Does it make sense to even go with a web-environment for the kind of game that I want to make? Does anyone have any experiences with decisions like this? Thanks! (* With the exception of flash-based engines it seems like most of the other approaches have these downsides when compared to what is available for desktop-based environments. I'd go with flash, but I'm worried that flash's 3D capabilities aren't mature enough right now to do what I want easily. There's also Unity3D, but I'm not sure how I feel about that at all. It seems highly polished, but requires a plugin to be downloaded for the game to be played -- at that rate I might as well have players download my game.)

• LTSP keeping sessions active whilst turning off thin clients

  - by map7

  I'm using LTSP on a Ubuntu 10.04 64bit box with 8 thin clients. I would like to save power by automatically turning off the thin clients at night, but I would like to have the ability to resume the staff's session in the morning. Is it possible to keep a session running whilst turning off the LTSP thin client and resuming that session when you power up the thin client the next time? Could this work if you login to another thin client in the morning and resume your session?
