• ASP.NET Routing not working on IIS 7.0

  - by Rick Strahl

  I ran into a nasty little problem today when deploying an application using ASP.NET 4.0 Routing to my live server. The application and its Routing were working just fine on my dev machine (Windows 7 and IIS 7.5), but when I deployed (Windows 2008 R1 and IIS 7.0) Routing would just not work. Every time I hit a routed url IIS would just throw up a 404 error: This is an IIS error, not an ASP.NET error so this doesn’t actually come from ASP.NET’s routing engine but from IIS’s handling of expressionless URLs. Note that it’s clearly falling through all the way to the StaticFile handler which is the last handler to fire in the typical IIS handler list. In other words IIS is trying to parse the extension less URL and not firing it into ASP.NET but failing. As I mentioned on my local machine this all worked fine and to make sure local and live setups match I re-copied my Web.config, double checked handler mappings in IIS and re-copied the actual application assemblies to the server. It all looked exactly matched. However no workey on the server with IIS 7.0!!! Finally, totally by chance, I remembered the runAllManagedModulesForAllRequests attribute flag on the modules key in web.config and set it to true: <system.webServer> <modules runAllManagedModulesForAllRequests="true"> <add name="ScriptCompressionModule" type="Westwind.Web.ScriptCompressionModule,Westwind.Web" /> </modules> </system.webServer> And lo and behold, Routing started working on the live server and IIS 7.0! This seems really obvious now of course, but the really tricky thing about this is that on IIS 7.5 this key is not necessary. So on my Windows 7 machine ASP.NET Routing was working just fine without the key set. However on IIS 7.0 on my live server the same missing setting was not working. On IIS 7.0 this key must be present or Routing will not work. Oddly on IIS 7.5 it appears that you can’t even turn off the behavior – setting runtAllManagedModuleForAllRequests="false" had no effect at all and Routing continued to work just fine even with the flag set to false, which is NOT what I would have expected. Kind of disappointing too that Windows Server 2008 (R1) can’t be upgraded to IIS 7.5. It sure seems like that should have been possible since the OS server core changes in R2 are pretty minor. For the future I really hope Microsoft will allow updating IIS versions without tying them explicitly to the OS. It looks like that with the release of IIS Express Microsoft has taken some steps to untie some of those tight OS links from IIS. Let’s hope that’s the case for the future – it sure is nice to run the same IIS version on dev and live boxes, but upgrading live servers is too big a deal to do just because an updated OS release came out. Moral of the story – never assume that your dev setup will work as is on the live setup. It took me forever to figure this out because I assumed that because my web.config on the local machine was fine and working and I copied all relevant web.config data to the server it can’t be the configuration settings. I was looking everywhere but in the .config file forever before getting desperate and remembering the flag when I accidentally checked the intellisense settings in the modules key. Never assume anything. The other moral is: Try to keep your dev machine and server OS’s in sync whenever possible. Maybe it’s time to upgrade to Windows Server 2008 R2 after all. More info on Extensionless URLs in IIS Want to find out more exactly on how extensionless Urls work on IIS 7?

• How to tell X.org to reload input device module? (Working around suspend-to-ram crash on Acer laptop

  - by Vi

  When X.org boots up, Synaptics touchpad works well. But when I remove the module it falls back to /dev/input/mice and don't use normal driver even when touchpad is available again. Xorg.0.log: ... (II) XINPUT: Adding extended input device "Synaptics Touchpad" (type: TOUCHPAD) (--) Synaptics Touchpad: touchpad found # { rmmod psmouse && echo mem /sys/power/state && modprobe psmouse; } (WW) : No Device specified, looking for one... (II) : Setting Device option to "/dev/input/mice" ... How to tell X.org to try it's InputDevice again (without restarting X server)? P.S. rmmod psmouse is needed to prevent crashing of Acer Extensa 5220 when resuming from suspend-to-ram. Update: Found answer myself: Doing xinput set-int-prop "Synaptics Touchpad" "Device Enabled" 8 1 after reloading the kernel module reloads touchpad. Now suspend-to-ram works OK.

• How to use my computer as a Headset device for my phone with Bluetooth?

  - by TheJelly

  I want to extract the audio from my phone (the analog TV and FM/AM receiver mainly) and play it through my computer speakers. There is a headphone jack but it is of non-standard size (probably a micro-jack) and I do not have access to a shop that sells that kind of equipment in my area so doing this with Bluetooth is the only solution I can foresee. Both my laptop and my phone support A2DP but for some reason the service (from the phone) does not show up while I add a new connection and the phone does not let me initiate a connection with any other profile except FTP (although it detects other services in the service list like A2DP and works perfectly fine with other profiles like DUN, HID, OPP, SSP if the connection is started through the computer). I am currently using the latest version of the Toshiba stack, I have tried using WIDCOMM but it refuses to install drivers for both the internal Bluetooth (which is a Broadcom device) and the USB Bluetooth that I use on my desktop. The standard Microsoft stack (generic driver) does install but it does not work with both of my devices as they do not detect any Bluetooth devices when scanning. With BlueSoleil (the default stack that came with the USB Bluetooth) I could set my device as "headset" instead of only "laptop/desktop", and this allowed both my phones to detect my laptop as a device they can use as a headset, but the problem with this stack was that only the older phone could actually connect to my laptop and that the internal Bluetooth could not be used. Basically, I want to set the device type as a "headset" for my phone using the Toshiba stack like I did with BlueSoleil. Is there any way this could be done? Thanks.

• Internet key not always detected by the operating system

  - by Carlo Gisonni

  I've over the time, tried and installed several versions of Ubuntu. Those versions I like more than others are: Lubuntu and Kubuntu. Everything seems to work properly but the Internet key. I do not know if it may depends on the weather, the moonphase or the tides but the Internet key is not always detected by the system and is sometimes very difficult to establish a connection when I do need to connect to internet. Without applyng any change sometimes works sometimes not. I've so far not found the solution and I think is a quite strange behaviour of the operating system as if the settings are wrong, should never work Awaiting a kind answer from those of you willing to help.

• Flash is not working in Chrome

  - by Jim Ford

  I have google Chrome 8.0.552.237 on Ubuntu 10.10 64-bit and flash is not working, I have tried a variety of methods to install flash, including Firefox flash-aid and the flash-installer package and nothing is working for me.

• what firefall linux distro applicance could track internet usage per device in my home?

  - by GregH

  Hello, Anyone know of a community edition/open source/free firewall/gateway software product that I could install onto an old PC to act as my firewall/gateway/proxy etc, BUT for which it has the power to track internet usage per device in my home. So: a) Mandatory - Track internet usage for devices on my home network on a per device basis (e.g. various PCs/Xbox etc) b) Mandatory - Report/graph would would give a breakdown of internet usage, per device (e.g. IP address), per day. c) Desirable - as in b) above but per hour d) Desirable - realtime graph (e.g. 5 minute measurement intervals or something) that shows current internet usage per device e) Mandatory - Handles all internal<=internet requests for all protocols (e.g. HTTP, HTTPS, xbox etc) f) Mandatory - No explicit settings in clients required - i.e. Transparent Monitoring concept (for both HTTP and non-HTTP traffic like xbox, skype etc) g) Mandatory - easy "appliance" like installation onto a dedicated low spec PC thanks in advance

• openGL migration from SFML to glut, vertices arrays or display lists are not displayed

  - by user3714670

  Due to using quad buffered stereo 3D (which i have not included yet), i need to migrate my openGL program from a SFML window to a glut window. With SFML my vertices and display list were properly displayed, now with glut my window is blank white (or another color depending on the way i clear it). Here is the code to initialise the window : int type; int stereoMode = 0; if ( stereoMode == 0 ) type = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH; else type = GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH | GLUT_STEREO; glutInitDisplayMode(type); int argc = 0; char *argv = ""; glewExperimental = GL_TRUE; glutInit(&argc, &argv); bool fullscreen = false; glutInitWindowSize(width,height); int win = glutCreateWindow(title.c_str()); glutSetWindow(win); assert(win != 0); if ( fullscreen ) { glutFullScreen(); width = glutGet(GLUT_SCREEN_WIDTH); height = glutGet(GLUT_SCREEN_HEIGHT); } GLenum err = glewInit(); if (GLEW_OK != err) { fprintf(stderr, "Error: %s\n", glewGetErrorString(err)); } glutDisplayFunc(loop_function); This is the only code i had to change for now, but here is the code i used with sfml and displayed my objects in the loop, if i change the value of glClearColor, the window's background does change color : glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glClearColor(255.0f, 255.0f, 255.0f, 0.0f); glLoadIdentity(); sf::Time elapsed_time = clock.getElapsedTime(); clock.restart(); camera->animate(elapsed_time.asMilliseconds()); camera->look(); for (auto i = objects->cbegin(); i != objects->cend(); ++i) (*i)->draw(camera); glutSwapBuffers(); Is there any other changes i should have done switching to glut ? that would be great if someone could enlighten me on the subject. In addition to that, i found out that adding too many objects (that were well handled before with SFML), openGL gives error 1285: out of memory. Maybe this is related. EDIT : Here is the code i use to draw each object, maybe it is the problem : GLuint LightID = glGetUniformLocation(this->shaderProgram, "LightPosition_worldspace"); if(LightID ==-1) cout << "LightID not found ..." << endl; GLuint MaterialAmbientID = glGetUniformLocation(this->shaderProgram, "MaterialAmbient"); if(LightID ==-1) cout << "LightID not found ..." << endl; GLuint MaterialSpecularID = glGetUniformLocation(this->shaderProgram, "MaterialSpecular"); if(LightID ==-1) cout << "LightID not found ..." << endl; glm::vec3 lightPos = glm::vec3(0,150,150); glUniform3f(LightID, lightPos.x, lightPos.y, lightPos.z); glUniform3f(MaterialAmbientID, MaterialAmbient.x, MaterialAmbient.y, MaterialAmbient.z); glUniform3f(MaterialSpecularID, MaterialSpecular.x, MaterialSpecular.y, MaterialSpecular.z); // Get a handle for our "myTextureSampler" uniform GLuint TextureID = glGetUniformLocation(shaderProgram, "myTextureSampler"); if(!TextureID) cout << "TextureID not found ..." << endl; glActiveTexture(GL_TEXTURE0); sf::Texture::bind(texture); glUniform1i(TextureID, 0); // 2nd attribute buffer : UVs GLuint vertexUVID = glGetAttribLocation(shaderProgram, "color"); if(vertexUVID==-1) cout << "vertexUVID not found ..." << endl; glEnableVertexAttribArray(vertexUVID); glBindBuffer(GL_ARRAY_BUFFER, color_array_buffer); glVertexAttribPointer(vertexUVID, 2, GL_FLOAT, GL_FALSE, 0, 0); GLuint vertexNormal_modelspaceID = glGetAttribLocation(shaderProgram, "normal"); if(!vertexNormal_modelspaceID) cout << "vertexNormal_modelspaceID not found ..." << endl; glEnableVertexAttribArray(vertexNormal_modelspaceID); glBindBuffer(GL_ARRAY_BUFFER, normal_array_buffer); glVertexAttribPointer(vertexNormal_modelspaceID, 3, GL_FLOAT, GL_FALSE, 0, 0 ); GLint posAttrib; posAttrib = glGetAttribLocation(shaderProgram, "position"); if(!posAttrib) cout << "posAttrib not found ..." << endl; glEnableVertexAttribArray(posAttrib); glBindBuffer(GL_ARRAY_BUFFER, position_array_buffer); glVertexAttribPointer(posAttrib, 3, GL_FLOAT, GL_FALSE, 0, 0); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, elements_array_buffer); glDrawElements(GL_TRIANGLES, indices.size(), GL_UNSIGNED_INT, 0); GLuint error; while ((error = glGetError()) != GL_NO_ERROR) { cerr << "OpenGL error: " << error << endl; } disableShaders();

• Major Google not follow increase since introducing 301 to site

  - by jakob

  Recently we implemented Varnish in front of our web nodes so that the backend would get some rest from time to time. Since varnish is case sensitive and our app was not we implemented a 301 in varnish to redirect to small case. Example: You search for PlumBer StockHOLM you will get a 301 redirect to plumber stockholm and then plumber stockholm will be cached. This worked as a charm, but when checking the Google webmaster tools we suddenly got a crazy amount of Status - Not able to follow errors. As you can see in the image below: This of course stirred up some panic and I started to read up on the documentation once again. If I pressed on one of the links I got to the help section where i found this: Well this is strange, but as the day progressed more and more errors were thrown by Google. We took the decision to make varnish return 200 instead of the 301. Now when testing the links that appears in the Not able to follow section I get a 200 back. I have tested with Chrome, curl and lynx reader and everything looks ok but the amount of errors are still increasing. What is a little bit comforting is that the links that appears in the Not able to follow section are dated before the 200 change in varnish. Why do I get these errors and why do they keep increasing? Did google release something new on October 31? Maybe I do not understand the docs correctly?

• Broadcom BCM4331 not working on new Mac Mini 5,1

  I can't seem to get my wireless card working on my Mac Mini 5,1. Lspci returns: 03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02) But running "additional drivers" doesn't detect anything. The nm-applet menu reads "device not ready--firmware missing." What can I do to get this to work? Note, this is with 12.04.1, so many of the previous discussions (for 11.10, etc) probably don't apply here.

• configure: error: Could not find libavformat - part of ffmpeg after installing libav from source

After downloading version 1.1.3 I tried to compile but I needed libav headers which I couldn't install via apt - no idea why there has been a lot of broken packages: $ sudo apt-get install libavcodec-dev Reading package lists...

• Why (not) logic programming?

  - by Anto

  I have not yet heard about any uses of a logical programming language (such as Prolog) in the software industry, nor do I know of usage of it in hobby programming or open source projects. It (Prolog) is used as an academic language to some extent, though (why is it used in academia?). This makes me wonder, why should you use logic programming, and why not? Why is it not getting any detectable industry usage?

• how to set owner and permission to a cryptsetup made device?

  - by Antoine Rodriguez

  I have an encrypted loopback volume. I need to mount and umount manually the volume so I use cryptsetup luksOpen and cryptsetup luksClose . However, When I invoke this command it pops up the /dev/mapper device under all the sessions under gnome/xfce/kde/unity ... And then it let the user to mount (with password), expulse and unmount the volume. It's quite annoying in a multi user server (you are working on your files and the volume is being unmounted). How can I define ownership and permission on the device ? I've tried chown and chmod approach witch gives nothing. Cryptsetup doesn't have any options that let you do that. crypttab auto mount the filesystem on boot witch is unwanted (only manual mount)

  I am over 18 hours deep on this challenge. I got to this point and am stuck. very stuck. Maybe you can figure it out? Ubuntu Version 12.04 LTS with all the updates installed. Problem: The default settings in "etc/X11/xorg.conf" that are generated by the "nvidia-xconfig" tool, do not allow the NVIDIA x server to connect to the driver in my "System Settings Additional Driver window". (that's how I understand it. Lots of information below). Symptoms of Problem "System Settings Additional Driver" window has drivers, but the nvidia x server cannot connect/utilize any of the 4 drivers. the drivers are activated, but not in use. When I go to "System Tools Administration NVIDIA x server settings" I get an error that basically tells me to create a default file to initialize the NVIDIA X server (screen shot below). This is the messages the terminal gives after running a "sudo nvidia-xconfig" command for the first time. It seems that the generated file by the tool i just ran is generating a bad/unusable file: If I run the "sudo nvidia-xconfig" command again, I wont get an error the second time. However when I reboot, the default file that is generated (etc/X11/xorg.conf) simply puts the screen resolution at 800 x 600 (or something big like that). When I try to go to NVIDIA x server settings I am greeted with the same screen as the screen shot as in symptom 2 (no option to change the resolution). If I try to go to "system settings display" there are no other resolutions to choose from. At this point I must delete the newly minted "xorg.conf" and reinstate the original in its place. Here are the contents of the "xorg.conf" that is generated first (the one missing required information): # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 304.88 (buildmeister@swio-display-x86-rhel47-06) Wed Mar 27 15:32:58 PDT 2013 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection Hardware: I ran the "lspci|grep VGA". There results are: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [Quadro 1000M] (rev a1) More Hardware info: Ram: 16GB CPU: Intel Core i7-2720QM @2.2GHz * 8 Other: 64 bit. This is a triple boot computer and not a VM. Attempts With Not Success on My End: 1) Tried to append the "xorg.conf" with what I perceive is missing information and obviously it didn't fly. 2) All the other stuff I tried got me to this point. 3) See if this link is helpful to you (I barely get it, but i get enough knowing that a smarter person might find this useful): http://manpages.ubuntu.com/manpages/lucid/man1/nvidia-xconfig.1.html 4) I am completely new to Linux (40 hours over past week), but not to programming. However I am very serious about changing over to Linux. When you respond (I hope someone responds...) please respond in a way that a person new to Linux can understand. 5) By the way, the reason I am in this mess is because I MUST have a second monitor running from my laptop, and "System Settings Display" doesn't recognize my second display. I know it is possible to make the second display work in my system, because when I boot from the install CD, I perform work on the native laptop monitor, but the second monitor shows a purple screen with Ubuntu in the middle, so I know the VGA port is sending a signal out. If this is too much for you to tackle please suggest an alternative method to get a second display. I don't want to go to windows but I cannot have a single display. I am really fudged here. I hope some smart person can help. Thanks in advance. Mike. **********************EDIT #1********************** More Details About Graphics Card I was asked "which brand of nvidia-card do you have exactly?" Here is what I did to provide more info (maybe relevant, maybe not, but here is everything): 1) Took my Lenovo W520 right apart to see if there is an identifier on the actual card. However I realized that if I get deep enough to take a look, the laptop "won't like it". so I put it back together. Figuring out the card this way is not an option for me right now. 2) (My computer is triple boot) I logged into Win7 and ran 'dxdiag' command. here is the screen shot: 3) I tried to look on the lenovo website for more details... but no luck. I took a look at my receipts and here is info form receipt: System Unit: W520 NVIDIA Quadro 1000M 2GB 4) In win7 I went to the NVIDIA website and used the option to have my card 'scanned' by a Java applet to determine the latest update for my card. I tried the same with Ubuntu but I can't get the applet to run. Here is the recommended driver from from the NVIDIA Applet for my card for Win7 (I hope this shines some light on the specifics of the card): Quadro/NVS/Tesla/GRID Desktop Driver Release R319 Version: 320.00 WHQL Release Date: 3.5.2013 5) Also I went on the NVIDIA driver search and looked through every possible combination of product type + product series + product to find all the combinations that yield a 1000M card. My card is: Product Type: Quadro Product Series: Quadro Series (Notebooks) Product: 1000M ***********************EDIT #2******************* Additional Symptoms Another question that generated more symptoms I previously didn't mention was: "After generating xorg.conf by nvidia-xconfig, go to additional drivers, do you see nvidia-304?" 1) I took a screen shot of the "additional drivers" right after generating xorg.conf by nvidia-xconfig. Here it is: 2) Then I did a reboot. Now Ubuntu is 600 x 800 resolution. When I logged in after the computer came up I got an error (which I always get after generating xorg.conf by nvidia-xconfig and rebooting) 3) To finally answer the question - No. There is no "NVIDIA-304" driver. Screen shot of additional drivers after generating xorg.conf by nvidia-xconfig and rebooting : At this point I revert to the original xorg.conf and delete the xorg.conf generated by Nvidia.

  - by Faisal Haq Salafi

  I've upgraded from Ubuntu 13.04 to Ubuntu 13.10, then ibus-avro for Bengali is not working. I've tried to reinstall ibus but no success. ibus-avro Icon is showing but not sure whats the problem. It should be working like this... The icon on top is showing properly, but it's not working. May be there are some communication problem. So currently after upgrade it's like this... As we can see the Bangla text is not appearing... I've tried these steps...But no hope. rm ~/.candidate-selections.json and sudo killall ibus-daemon ibus-daemon -vx Then /usr/bin/env gjs --include-path=/usr/share/ibus-avro /usr/share/ibus-avro/main-gjs.js

• Sitronix ST9RM01 touchscreen not working

  - by Josh Kelley

  I have a Sitronix ST9RM01 touchscreen that I'm trying to get working with Ubuntu 12.04. The touchscreen is apparently recognized by Linux and X - the hid_multitouch module is loaded, and lsinput and xinput both list the touchscreen as an input device - but touching the screen does absolutely nothing, and xinput test shows no events. The same touchscreen works just fine in Windows. How can I troubleshoot from here? Any suggestions?
