  • Trying to use HUAWEI E173 on Ubuntu 12.04

    - by Scott Warren
    I have a HUAWEI E173 usb stick to access the internet. It works normally on windows but I need to use it on my Ubuntu system. I plug it in, and after 25-20 seconds the status light turns green and blinks twice every 3 seconds. I see no changes in my system whatsoever, nothing gets installed, I don't get prompted for my PIN. I tried to create a connection using edit connections. I entered the following parameters: Turkey, Turkcell, My Plan is not listed, Internet. Nothing happens. I tried the lsusb command and got the following: tosh2000@tosh:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 058f:a001 Alcor Micro Corp.

  • Different behaviour with windows authentication on IIS7 websites

    - by amaters
    I need to run a website with just windows authentication. Given the following situation: The location of the default website is: c:\inetpub\wwwroot The location of my code is: c:\Sites\WebApp my hostfile is edited so any .local i use points to 127.0.0.1 I have created a new application called 'AppX' underneath the default website and point it to c:\Sites\WebApp. It will use the DefaultappPool. When I switch off anonymous and switch on windows authentication all works well when I go to localhost/AppX/. What i really want is a new website (No need to question why I want this). So I created Website2 and did exact the same creation of the application. Everything is the same; destination, app pool and authentication. Now when I browse to this website web2.local/AppX/ I get the 401.2 - Unauthorized error. What am I missing here?

  • Is there a way to update all Java related alternatives?

    - by James McMahon
    Is there a way to quickly switch over all the Java related alternatives using update-alternatives? For instance, if want to switch Java over to 7, I run sudo update-alternatives --config java and select the Java 7 OpenJdk.

  • Plan Operator Tuesday round-up

    - by Rob Farley
    Eighteen posts for T-SQL Tuesday #43 this month, discussing Plan Operators. I put them together and made the following clickable plan. It’s 1000px wide, so I hope you have a monitor wide enough. Let me explain this plan for you (people’s names are the links to the articles on their blogs – the same links as in the plan above). It was clearly a SELECT statement. Wayne Sheffield (@dbawayne) wrote about that, so we start with a SELECT physical operator, leveraging the logical operator Wayne Sheffield. The SELECT operator calls the Paul White operator, discussed by Jason Brimhall (@sqlrnnr) in his post. The Paul White operator is quite remarkable, and can consume three streams of data. Let’s look at those streams. The first pulls data from a Table Scan – Boris Hristov (@borishristov)’s post – using parallel threads (Bradley Ball – @sqlballs) that pull the data eagerly through a Table Spool (Oliver Asmus – @oliverasmus). A scalar operation is also performed on it, thanks to Jeffrey Verheul (@devjef)’s Compute Scalar operator. The second stream of data applies Evil (I figured that must mean a procedural TVF, but could’ve been anything), courtesy of Jason Strate (@stratesql). It performs this Evil on the merging of parallel streams (Steve Jones – @way0utwest), which suck data out of a Switch (Paul White – @sql_kiwi). This Switch operator is consuming data from up to four lookups, thanks to Kalen Delaney (@sqlqueen), Rick Krueger (@dataogre), Mickey Stuewe (@sqlmickey) and Kathi Kellenberger (@auntkathi). Unfortunately Kathi’s name is a bit long and has been truncated, just like in real plans. The last stream performs a join of two others via a Nested Loop (Matan Yungman – @matanyungman). One pulls data from a Spool (my post – @rob_farley) populated from a Table Scan (Jon Morisi). The other applies a catchall operator (the catchall is because Tamera Clark (@tameraclark) didn’t specify any particular operator, and a catchall is what gets shown when SSMS doesn’t know what to show. Surprisingly, it’s showing the yellow one, which is about cursors. Hopefully that’s not what Tamera planned, but anyway...) to the output from an Index Seek operator (Sebastian Meine – @sqlity). Lastly, I think everyone put in 110% effort, so that’s what all the operators cost. That didn’t leave anything for me, unfortunately, but that’s okay. Also, because he decided to use the Paul White operator, Jason Brimhall gets 0%, and his 110% was given to Paul’s Switch operator post. I hope you’ve enjoyed this T-SQL Tuesday, and have learned something extra about Plan Operators. Keep your eye out for next month’s one by watching the Twitter Hashtag #tsql2sday, and why not contribute a post to the party? Big thanks to Adam Machanic as usual for starting all this. @rob_farley

  • rvmsudo foreman export upstart without asking for password

    - by Millisami
    My capistrano deploy.rb has a foreman export command for a rails app on Ubuntu 10.04 So, while deploying, I want to export the foreman to upstart script. But doing that, the command rvmsudo foreman export ... asks for root password and I cannot do anything. Googled a lot and tried with various tweaks but nothing worked. * executing `foreman:export' * executing "cd /home/deploy/zappy/releases/20111019175422 && rvmsudo foreman export upstart /etc/init -a zappy -u deploy -f ./Procfile.production -c worker=1 redis=1 -l /home/deploy/zappy/releases/20111019175422/log/foreman" servers: ["173.255.205.237"] [173.255.205.237] executing command ** [out :: 173.255.205.237] [sudo] password for deploy: What could be the solution to do it password-less way?

  • NTP service, offset increasing after sync

    - by Ajay
    I have installed Ubuntu 12.10 version on my PC. I am running NTP service having NTP server as GPS. I found that when we start NTP service by ntp start command, PC is able to sync with GPS as i get '*' symbol before GPS IP when i run ntpq -p command. This remains good for some time and then the * symbol is removed which means that PC is not synchronized to that server. Now, by running command ntpq -p it shows that all parameter are OK but as '*' is removed, slowly offset goes on increasing. remote refid st t when poll reach delay offset jitter ============================================================================== *192.168.100.33 .GPS. 1 u 7 16 1 2.333 23.799 0.808 remote refid st t when poll reach delay offset jitter ============================================================================== *192.168.100.33 .GPS. 1 u 14 16 3 2.333 23.799 0.879 remote refid st t when poll reach delay offset jitter ============================================================================== *192.168.100.33 .GPS. 1 u 11 16 7 2.333 23.799 1.500 remote refid st t when poll reach delay offset jitter ============================================================================== *192.168.100.33 .GPS. 1 u 8 16 17 2.333 23.799 2.177 below are the last 4 ntp status when sync is lost with GPS ============================================================================== 192.168.100.33 .GPS. 1 u 1 16 377 2.404 1169.94 1.735 remote refid st t when poll reach delay offset jitter ============================================================================== 192.168.100.33 .GPS. 1 u - 16 377 2.513 1171.80 0.898 remote refid st t when poll reach delay offset jitter ============================================================================== 192.168.100.33 .GPS. 1 u 15 16 377 2.513 1171.80 0.898 Since, GPS is already available, PC never re-synchronize itself to GPS later ON.

  • Looking for zsh completion file for osX native commands

    - by Chiggsy
    I've been digging deep into what actually comes with osX in /usr/bin and especially /usr/libexec. Quite good stuff really, although the command syntax is a bit.. odd. Let me direct the curious to the command that made me think of this: networksetup -printcommands I can not think of a command that better illustrates the need for good completion. security -h perhaps, but those commands have a familiar easy-to-read format. I beseech the community, please point me to a place where I can find such a thing. I never type them right, and I ache for tab completion for this Anyone have any idea where I could grab something? I'd prefer to stand on the shoulders of giants instead of trying to make a zsh/bash completion script leap into the world, ready for battle, like Athena, from my forehead. I am no Zeus when it comes to compctl. Not at all.

  • How to change the screen resolution in VNC viewer for Ubuntu 12.04 without a monitor?

    - by user325320
    I have Ubuntu 12.04 installed on a machine and I always use it remotely from VNC. When I have monitor connected to this machine, I can change the resolution of my VNC viewer in the following line: $vnc4server --geometry 1440x900 This worked for me, but I always use this machine remotely, I unplug the monitor and reboot. and the above command line not work anymore. Then I tried xrandr SZ: Pixels Physical Refresh *0 1024 x 768 ( 260mm x 195mm ) *60 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none There is only one option available, so I tried to add a new one. $cvt 1440 900 # 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz Modeline "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync $xrandr --newmode "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync $xrandr --addmode S2 "1440x900_60.00" then I checked with xrandr again and can't see the new mode added. I try to execute the following command and get error says my RandR is too old. $xrandr --output S2 --mode 1440x900_60.00 xrandr: Server RandR version before 1.2 but this does not make sense to me, if I plug in the monitor back and run the xrandr command, it works again! It seems that Ubuntu must conntect to a real monitor before I can change my resolution in my VNC viewer. Can anyone help? UPDATE: Finally I solved this problem by changing to tightvncserver $tightvncserver -geometry 1440x900 works for me. Thanks everything answered my question

  • gVIM "put" driving me mad, how do I "put" at the beginning of a line

    - by crgnz
    I'm learning gVIM on Windows, and as I slowly learn more of the keystrokes I find myself using the mouse less and less, which is great. I have a couple of questions I've yet to figure out: I do a lot of copy and paste. So I use 'v' to enter VISUAL mode, use k/j to move up/down and select the lines, then hit 'y' to yank. I then go to the line where I want to insert, and hit 'p' to put, BUT the darn thing pastes after the 1st character. I can't move any further left, so I am definitely at the start of the line, so I find the 'p'ut behaviour of pasting 1 char after my cursor position to be supremely annoying. I switch between edit and command mode an awful lot, and my poor little finger on my left hand is getting sore from being stretched out to hit the 'Esc' key (to enter command mode) every few seconds. Is there a more finger-friendly way to enter command mode?

  • BizTalk - Removing BAM Activities and Views using bm.exe

    Originally posted on: http://geekswithblogs.net/StuartBrierley/archive/2013/10/16/biztalk---removing-bam-activities-and-views-using-bm.exe.aspxOn the project I am currently working on, we are making quite extensive use of BAM within our growing number of BizTalk applications, all of which are being deployed and undeployed using the excellent Deployment Framework for BizTalk 5.0.Recently I had an issue where problems on the build server had left the target development servers in a state where the BAM activities and views for a particular application were not being removed by the undeploy process and unfortunately the definition in the solution had changed meaning that I could not easily recreate the file from source control.  To get around this I used the bm.exe application from the command line to manually remove the problem BAM artifacts - bm.exe can be found at the following path:C:\Program Files (x86)\Microsoft BizTalk Server 2010\TrackingC:\Program Files (x86)\Microsoft BizTalk Server 2010\TrackingStep1 :Get the BAM Definition FileRun the following command to get the BAm definition file, containing the details of all the activities, views and alerts:bm.exe get-defxml -FileName:{Path and File Name Here}.xmlStep 2: Remove the BAM ArtifactsAt this stage I chose to manually remove each of my problem BAM activities and views using seperate command line calls.  By looking in the definition file I could see the names of the activities and views that I wanted to remove and then use the following commands to remove first the views and then the activities:bm.exe remove-view -name:{viewname}bm.exe remove-activity -name:{activityname}

  • Looking into ASP.Net MVC 4.0 Mobile Development - part 2

    - by nikolaosk
    In this post I will be continuing my discussion on ASP.Net MVC 4.0 mobile development. You can have a look at my first post on the subject here . Make sure you read it and understand it well before you move one reading the remaining of this post. I will not be writing any code in this post. I will try to explain a few concepts related to the MVC 4.0 mobile functionality. In this post I will be looking into the Browser Overriding feature in ASP.Net MVC 4.0. By that I mean that we override the user agent for a given user session. This is very useful feature for people who visit a site through a device and they experience the mobile version of the site, but what they really want is the option to be able to switch to the desktop view. "Why they might want to do that?", you might wonder.Well first of all the users of our ASP.Net MVC 4.0 application will appreciate that they have the option to switch views while some others will think that they will enjoy more the contents of our website with the "desktop view" since the mobile device they view our site has a quite large display.  Obviously this is only one site. These are just different views that are rendered.To put it simply, browser overriding lets our application treat requests as if they were coming from a different browser rather than the one they are actually from. In order to do that programmatically we must have a look at the System.Web.WebPages namespace and the classes in it. Most specifically the class BrowserHelpers. Have a look at the picture below   In this class we see some extension methods for HttpContext class.These methods are called extensions-helpers methods and we use them to switch to one browser from another thus overriding the current/actual browser. These APIs have effect on layout,views and partial views and will not affect any other ASP.Net Request.Browser related functionality.The overridden browser is stored in a cookie. Let me explain what some of these methods do. SetOverriddenBrowser() -  let us set the user agent string to specific value GetOverriddenBrowser() -  let us get the overridden value ClearOverriddenBrowser() -  let us remove any overridden user agent for the current request   To recap, in our ASP.Net MVC 4.0 applications when our application is viewed in our mobile devices, we can have a link like "Desktop View" for all those who desperately want to see the site with in full desktop-browser version.We then can specify a browser type override. My controller class (snippet of code) that is responsible for handling the switching could be something like that. public class SwitchViewController : Controller{ public RedirectResult SwitchView(bool mobile, string returnUrl){if (Request.Browser.IsMobileDevice == mobile)HttpContext.ClearOverriddenBrowser();elseHttpContext.SetOverriddenBrowser(mobile ? BrowserOverride.Mobile : BrowserOverride.Desktop);return Redirect(returnUrl);}} Hope it helps!!!!

  • Is it possible to show " New Task" of Task Manager from tasks of Task Manager only?

    - by WebMAOhist
    I work on remote Windows Server 2008 machine over RDP and frequently need to revive broken copy&pasting over RDP. Which is killing rdpclip process in Task Manger (tab "Processes") and launching it gain by: switching to tab Applications -- pressing button "New Task..." -- typing 'rdpclip'-- clicking OK. Well, I do not need to type 'rdpclip' if it is the last used command. The problem that in "Create New Task" of Windows Task Manager I always launch rdpclip only but it shows the last run program from Windows command prompt (Win +R), usually it is "notepad" for me. Is it possible to bind the last used command/task to Task Manager only? and how?

  • New Xming Windows Doesn't Grab Focus

    - by Isaac Rabinovitch
    I do my day-to-day work on Windows 7 (no, that's not going to change) and often need to work with Linux running on Parallels. Switching between Windows and Linux desktops is a pain, so I've installed Cygwin+Xming (less complicated than CygwinX). I open a Cygwin command line using mintty, then do ssh -Y to get a Linux command line. Doing "vim" on the Linux command line causes the vim window to appear on my Windows desktop. This is great, except that the new vim window doesn't automatically grab the focus, which stays with the mintty window. Years of habit cause me to start typing immediately without clicking on the new window. Having to switch manually is very jarring. Any way to make it automatic?

  • Writing a "Hello World" Device Driver for kernel 2.6 using Eclipse

    - by Isaac
    Goal I am trying to write a simple device driver on Ubuntu. I want to do this using Eclipse (or a better IDE that is suitable for driver programming). Here is the code: #include <linux/module.h> static int __init hello_world( void ) { printk( "hello world!\n" ); return 0; } static void __exit goodbye_world( void ) { printk( "goodbye world!\n" ); } module_init( hello_world ); module_exit( goodbye_world ); My effort After some research, I decided to use Eclipse CTD for developing the driver (while I am still not sure if it supports multi-threading debugging tools). So I: Installed Ubuntu 11.04 desktop x86 on a VMWare virtual machine, Installed eclipse-cdt and linux-headers-2.6.38-8 using Synaptic Package Manager, Created a C Project named TestDriver1 and copy-pasted above code to it, Changed the default build command, make, to the following customized build command: make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 The problem I get an error when I try to build this project using eclipse. Here is the log for the build: **** Build of configuration Debug for project TestDriver1 **** make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 all make: Entering directory '/usr/src/linux-headers-2.6.38-8-generic' make: *** No rule to make target vmlinux', needed byall'. Stop. make: Leaving directory '/usr/src/linux-headers-2.6.38-8-generic' Interestingly, I get no error when I use shell instead of eclipse to build this project. To use shell, I just create a Makefile containing obj-m += TestDriver1.o and use the above make command to build. So, something must be wrong with the eclipse Makefile. Maybe it is looking for the vmlinux architecture (?) or something while current architecture is x86. Maybe it's because of VMWare? As I understood, eclipse creates the makefiles automatically and modifying it manually would cause errors in the future OR make managing makefile difficult. So, how can I compile this project on eclipse?

  • Vim: :silent with makeprg

    - by ash
    I use pylint on .py files for :make in my .vimrc, although any program, pylint or otherwise, applies to this problem. set makeprg=pylint\ --reports=n\ --output-format=parseable\ % When I run :make, I inevitably get the annoying Press ENTER or type command to continue prompt. I know this can be disabled with :silent, but I can't prepend it to the makeprg variable like this, because it throws an error: set makeprg=:silent "pylint\ --reports=n\ --output-format=parseable\ %" If I try to have my own "Silent make command," command Smake silent make The screen goes black after calling it. How would I do it?

  • Troubleshoot broken ZFS

    - by BBK
    I have one zpool called tank in RaidZ1 with 5x1TB SATA HDDs. I'm using Ubuntu Server 11.10 Oneric, kernel 3.0.0-15-server. Installed ZFS from ppa also I'm using zfs-auto-snapshot. The ZFS file system when zfs module loaded to the kernel hangs my computer. Before it I created few new file systems: zfs create -V 10G tank/iscsi1 zfs create -V 10G tank/iscsi2 zfs create -V 10G tank/iscsi3 I shared them through iSCSI by /dev/tank/iscsiX path. And my computer started to hanging sometimes when I used tank/iscsiX by iSCSI, do not know why exactly. I switched off iSCSI and started to remove this file systems: zfs destroy tank/iscsi3 I'm also using zfs-auto-snapshot so I had snapshots and without -r key my command not destroying the FS. So I issued next command: zfs destroy tank/iscsi3 -r The tank/iscsi3 FS was clean and contain nothing - it was destroyed without an issue. But tank/iscsi2 and tank/iscsi1 contained a lot of information. I tried zfs destroy tank/iscsi2 -r After some time my computer hang out. I rebooted computer. It didn't boot very fast, HDDs starts working like a crazy making a lot of noise, after 15 minutes HDDs stopped go crazy and OS booted at last. All seems to be ok - tank/iscsi2 was destroyed. After file systems at the tank was accessible, zpool status showed no corruption. I issued new command: zfs destroy tank/iscsi1 -r Situation was repeated - after some time my computer hang out. But this time ZFS seams not to healed itself. After computer switched on it started to work: loading scripts and kernel modules, after zfs starting to work it hanging my computer. I need to recover else ZFS file systems which lying in the same zpool. Few month ago I backup OS to flash drive. Booting from backed-up OS and import have the same results - OS starts hanging. How to recover my data at ZFS tank?

  • Synaptic won't launch from menu in panel in fresh Lubuntu minimal desktop 12.04 install

    - by ven42
    I performed a fresh install of Lubuntu 12.04 with minimal desktop, as described here: https://help.ubuntu.com/community/Lubuntu/Documentation/MinimalInstall. To clarify, I did a command-line install from the Lubuntu alternative install disc, then I did an "apt-get install --no-install-recommends lubuntu-desktop". Everything is working fine, except that Synaptic will not run from the menu entry in the panel. I am not prompted for a password, and no window of any sort appears after clicking the menu entry. I installed lxshortcut to see what the shortcut was running, and the command is "synaptic-pkexec". If I type this command into the "Run" menu, I get the same behavior (or lack thereof). I can get Synaptic to open up just fine by typing "gksudo synaptic" at the "Run" menu. Also, if I run "synaptic-pkexec" from the terminal, then I am prompted for my password within the terminal, and after that Synaptic opens normally. Can someone please suggest the right way to get Synaptic working? I could just change the menu entry to "gksudo synaptic", but I'm guessing that it's set to "synaptic-pkexec" for a reason. I have a vague understanding that this pkexec business has something to do with PolicyKit, but I don't really know what PolicyKit is or how to tell if something is broken with it. Thanks.

  • Proper way to remove an active / inactive LVM snapshot

    - by user2622247
    I have created a sample ruby script file for removing extra LVM snapshots from the system. For removing LVM snapshot, we are using lvremove command. This command is working fine and we can remove snapshots from the system. # sudo lvremove /dev/ops/dbbackup lvremove -- do you really want to remove "/dev/ops/dbbackup"? [y/n]: y Sometimes while removing snapshots we are getting following errors. Unable to deactivate open rootfs_12.10_20140812_00-cow (252:8) Failed to resume rootfs_12.10_20140812_00. libdevmapper exiting with 7 device(s) still suspended. The system gets frozen. We cannot fire any command or can not perform any action on it. After restarting the system, it is functioning fine. We can perform all the operations even we can delete that snapshot also. I searched about it I found these threads https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=659762 and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=674682 Solution from this thread is after getting the error but I have to avoid this type of error. I have a question, Is there any better way removing LVM snapshots? So that we can avoid this type of error. If anyone needs more info feel free to ask me.

  • How to stop a infinite running process(ztail) started by a ssh session after that session is closed

    - by Sanath Adiga
    I have a peculiar problem. My server supports multiple ssh session simultaneously, so that multiple admins can manage it simultaneously. We have a command which calls ztail to show the compressed log files and when the current ssh session is closed (without pressing ctrlc, to stop the tail command), the command should ideally stop working. But what I observed when I start a new ssh session is that the process ztail is still running in the background and consuming CPU, even though the previous session was closed. How can I determine when the session is closed, so that I can use that variable/flag to close/stop any commands initiated by that previously closed session?
