  • Mandatory Profiles on a Server 2003 TS Box

    - by Chloe
    I have a Windows Server 2003 box which will be acting as a terminal server. It will actually be running Citrix, but I don't believe that to be relevant here. There has been a request for every user to use a single mandatory profile. I've used mandatory profiles before, but there have been generally different profiles for different users so I've always used the "Terminal Services Profile" tab to good effect. What I'd like this time is a single setting, such as a Group Policy or similar that simply forces every non-domain admin user logging on to the box into using the mandatory profile. We'll be using Folder Redirection to take care of everything else. I'm aware of the following GPO: Computer Policy\Computer Configuration\Administrative Templates\Windows Components/Terminal Services Set path for TS Roaming Profiles But, as that's a computer policy, will it not apply to all users including administrators? If so, is it possible to exclude admins somehow?

  • Nagios Creating lots of zombie process

    - by pradeepchhetri
    In my monitoring box, I have lots of zombie process created by nagios and they gets remove quickly also. I am using active checks to perform monitoring of my servers. I accumulated the defunct processes created using the following command: $ top -d 0.25 -b -n 20 > topout.txt This collected the output of top with 0.25s delay 20 times. I did grep on the topout.txt for the defunct process. $ cat topout.txt | grep defunct I get the following output. 8957 nagios 20 0 0 0 0 Z 6.0 0.0 0:00.02 nagios <defunct> 8951 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 8954 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 8945 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 8946 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 8980 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9000 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.00 nagios <defunct> 9024 nagios 20 0 0 0 0 Z 7.0 0.0 0:00.02 nagios <defunct> 9025 nagios 20 0 0 0 0 Z 3.5 0.0 0:00.01 nagios <defunct> 9040 nagios 20 0 0 0 0 Z 3.1 0.0 0:00.01 nagios <defunct> 9086 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9087 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9123 nagios 20 0 0 0 0 Z 6.1 0.0 0:00.02 nagios <defunct> 9126 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 9131 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 9091 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.05 nagios <defunct> 9111 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9119 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9118 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9151 nagios 20 0 0 0 0 Z 2.9 0.0 0:00.02 nagios <defunct> 9153 nagios 20 0 0 0 0 Z 2.9 0.0 0:00.02 nagios <defunct> 9150 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9164 nagios 20 0 0 0 0 Z 3.5 0.0 0:00.02 nagios <defunct> 9171 nagios 20 0 0 0 0 Z 3.5 0.0 0:00.02 nagios <defunct> 9154 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9156 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9163 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9167 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9178 nagios 20 0 0 0 0 Z 3.8 0.0 0:00.02 nagios <defunct> 9174 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9179 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9182 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> Can somebody help me in finding out the reason of these zombie processes and how i can prevent these zombie processes ?

  • Can I trust that ZFS is consistent between Linux and FreeBSD?

    - by iconoclast
    I'm planning to build a FreeNAS box sometime soon, but if ZFS on Linux eventually proves to be reliable, I might want to switch, just to have a more familiar OS. So I'm wondering if I can trust that the different implementations of ZFS are compatible. In other words, if I just swap out the boot disk from FreeNAS to Linux or OpenIndiana, can I trust that nothing bad will happen to my data? This may seem like a stupid question--obviously it ought to be compatible--but I'm guessing that ZFS isn't commonly used in cases where drives are moved between computers, so I'm hoping someone can provide a better answer than just "it ought to be".

  • Enable basic auth sitewide and disabling it for subpages?

    - by piquadrat
    I have a relatively straight forward config: upstream appserver-1 { server unix:/var/www/example.com/app/tmp/gunicorn.sock fail_timeout=0; } server { listen 80; server_name example.com; location / { proxy_pass http://appserver-1; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; auth_basic "Restricted"; auth_basic_user_file /path/to/htpasswd; } location /api/ { auth_basic off; } } The goal is to use basic auth on the whole website, except on the /api/ subtree. While it does work with respect to basic auth, other directives like proxy_pass are not in effect on /api/ as well. Is it possible to just disable basic auth while retaining the other directives without copy&pasting everything?

  • SSH ForceCommand example - require a user to enter a token before getting shell access?

    - by consolibyte
    I'd like to prompt a user for some piece of information before they get to their BASH shell when they're logging in via SSH. Ideally, I'd like to execute a script which prompts them for information, check that the information is correct, and then if it is drop them to a shell. So, think: ssh [email protected] password: xxxx do you agree to the terms and conditions of use? enter yes or no: yes OK, here's your shell: # Can anyone provide an example of how to do something like this?

  • What is the difference between SoftAP and Wifi-Direct?

    - by user1129812
    I want to buy a Wifi Dongle that, besides acting as an ordinary Wifi client, could change its mode to work as an Access Point too. Should I buy a dongle with SoftAP or should I buy one with Wifi-Direct ? What is the difference between these 2 concepts ? Or is there any difference between them ? Moreover, what chipset (Realtek, Ralink etc) could provide such a functionality ? Which chipset that has this functionality could work happily in a Debian/Ubuntu 32 bit environment ? Thanks in advance for any suggestion.

  • Change from IDE to AHCI after installing Windows 8

    - by Louis
    I had my drive controller configured for IDE when I installed Windows 7. This didn't change when I upgraded to Windows 8. I now need to enable AHCI, but doing so causes Windows to fail to start. It doesn't know how to automatically fix the problem. I was able to use Regedit from the recovery area, in order to try using this fix that worked for Vista. That key is missing in Windows 8, however. I read that the relevant key is now in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci. But my settings already match the changes they suggest making. How can I get Windows to boot after enabling AHCI in the BIOS?

  • windows 7 vs linux on ssd

    - by wushugene
    Why did my old windows 7 install boot faster/run smoother & cooler than each the three linux distros I have recently tried (ubuntu 12.04 unity, linux mint 13 MATE, and fedora 17 on gnome 3.4)?. I have tweaked my linux installs for the ssd (enabling trim, disabling swap, etc.) I'm using an Acer TravelMate with i5-2410m processor, intel hd 3000 graphics, 8 gigs of ram, and a 256 gb samsung 830 ssd.

  • Windows Media Player Object with Video_TS Files - No Sound Anymore

    - by user1624184
    I copied a bunch of my DVDs (yes, owned) to a drive and created a basic webpage to be able to search and play them. I am using the code at the bottom to create a Windows Media Player object and then play the video. The video files are pulled off the DVD in the original format so each movie has files like this: VTS_01_0.BUP VTS_01_0.IFO VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB VTS_01_4.VOB VTS_01_5.VOB VTS_01_6.VOB This all worked great until just recently. On my dev machine, I can play the videos but now, all of a sudden, there is no sound. I have tried the following but no luck: The video is not muted and the sound is at 50% Under the sound icon, under mixer, I checked IE and it is fine Sound works fine using another program, says WinAmp Opening Windows Media Player directly from the Start Menu and then playing the same movie works fine and I get sound I ensured that the option in IE to play sound on websites is checked I can play sound on other people's websites where they have embedded WMP files I tried resetting all of the IE settings on the Advanced tab in IE I tried my website, with my code below on another computer, AND IT WORKS FINE! I tried copying the media files listed above from the computer that works fine to my dev computer and it still doesn't work. If I try using a ".wmv" file, the sound does work By the way, I am using Win7 with IE8. As you can see, this is driving me crazy! Why would it stop working on my one computer and the same code and files work fine on another computer? Any help would be greatly appreciated. <OBJECT id="mediaPlayer" width="640px" height="480px" style="position:absolute; left:0px; top:0px;" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" type="application/x-oleobject"> <PARAM NAME="URL" VALUE="E:\test\VIDEO_TS\VIDEO_TS.IFO" /> <PARAM NAME="SendPlayStateChangeEvents" VALUE="True"/> <PARAM NAME="AutoStart" VALUE="True"/> <PARAM NAME="uiMode" VALUE="full"/> <PARAM NAME="volume" VALUE="50" /> <PARAM NAME="PlayCount" VALUE="9999"/> <PARAM NAME="fullScreen" VALUE="true"/> <PARAM NAME="enableContextMenu" VALUE="true"/> </OBJECT>

  • Excel 2003 Freezes When Worksheet with PivotTable Selected

    - by Max
    All of the sudden, my Excel 2003 began an odd behavior today. Whenever I click on a worksheet tab that has a PivotTable on it, I become unable to click on any other tabs or on the menu with the options to minimize, maximize, and size at the top left of the worksheet window. I am left unable to click on the other tabs until I double-click inside a cell in the PivotTable worksheet and get a blinking curor as if to type. Then, I can navigate to other tabs normally. I can't think of any major changes I have made to my computer in the last day that would have caused this. I did instiall PC Tools antivirus over a week ago, and since that time have noticed my computer behaving in odd ways, but excel has been just fine until now. Does anyone have any thoughts on what might cause this? Thanks so much.

  • How to prevent laptop screen brightness from changing when un/plugging battery power

    - by Nomad
    When I am using my laptop, I continually adjust the screen's brightness based on the lighting conditions in the room (e.g. how much light is coming in from windows, etc.). But if I unplug the laptop or plug it back in, Windows looks at the default brightness setting in the power profile for "on battery" or "plugged in" and changes the brightness accordingly. This is a jarring experience and then I have to hunt down the ideal brightness for my current situation again, rather than getting on with my work. I would like to make it so that plugging or unplugging the battery is not a trigger that adjusts the screen brightness at all. The screen brightness should only change when I adjust it myself. Does anybody know how this might be accomplished?

  • How to repair the boot selection on grub?

    - by Zignd
    I had installed on my computer as a dual-boot: Debian Squeeze and Windows XP, so I decided to install Windows 8 just to test and then I would remove it and install in its place Debian Wheezy as dual-boot with Windows XP, that was already installed. During the Debian Wheezy installation, I deleted the Windows 8 partition to install Debian W. on its place. The problem is, that after the installation finished I rebooted the computer and on the grub menu was written: Debian Wheezy and Windows 8 (loader) - this Windows 8 (loader) is a boot manager as grub, and after the Win8 installation I was capable of choose between Win8 and WinXP. And when I select Windows 8 (loader) it says the Windows 8 is corrupted and is not possible to boot Windows XP. So, after that, I would like to know, how can I get Windows XP on the grub menu? Because I know its there (the Windows XP), but I can not boot it from grub. Observation: I already tried update-grub, but it only finds Debian W. and Windows 8.

  • sed: delete text between a string until first occurrence of another string

    - by Marit Hoen
    Imagine I have something like the following text: The quick brown fox jumps in 2012 and 2013 And I would wish to delete the part from "fox" including the four numbers but only in the first occurrence so I end up with: The quick brown and 2013 Something likes this...: echo "The quick brown fox jumps in 2012 and 2013" \ | sed "s/fox.*\([0-9]\{4\}\)//g" ...brings me: The quick brown So it removed everything including the last occurrence of the four numbers. Any ideas?

  • Tool to fix video that's out of sync with audio?

    - by Javier Badia
    I'm looking for (preferably free) software for Windows 7 that will allow me to fix an AVI file that has audio out of sync with the video. I tried with Windows Live Movie Maker and VirtualDub and couldn't find out how to do it (if at all possible) on both of them. If any of those can help me, instructions for that would also be nice. Background: I have a RCA-to-USB capture card, which I'm using to transfer VHS casettes and stuff from a video camera to digital format. The problem is that the audio comes out heavily distorted. So instead I connected the audio out from the VCR directly to the computer's line in. This works, but the audio is out of sync, about half a second behind the video. I could spend time trying to fix this issuee, but I think it'll be easier to simply fix the video.

  • SQL SERVER – Fun Post – Connecting Same SQL Server using Different Methods

    - by pinaldave
    Yesterday I had faced error when I was connecting SQL Server using 127.0.0.1. I had immediately checked if SQL Server is working perfectly by connecting to it by specifiing my local box computer. While I was doing this suddenly I realize that it is indeed interesting to know how many different way we can connect to SQL Server which is installed in the local box. I created list of 5 different way but I am sure there are many more ways and I would like to document there here. Here is my setup. I am attempting to connect to the default instance of SQL Server from the same system where it is installed. Method 1: Connecting using local host IP 127.0.0.1 Method 2: Connecting using just a single dot (.) Method 3: Connecting using (local) Method 4: Connecting using localhost Method 5: Connecting using computer name – in my case it is BIG Here are my two questions for you? (Scroll below the image) 1) Which is your favorite method? 2) What are other methods you are familiar with to connect to local host?

  • Programmaticaly finding the Landau notation (Big O or Theta notation) of an algorithm?

    - by Julien L
    I'm used to search for the Landau (Big O, Theta...) notation of my algorithms by hand to make sure they are as optimized as they can be, but when the functions are getting really big and complex, it's taking way too much time to do it by hand. it's also prone to human errors. I spent some time on Codility (coding/algo exercises), and noticed they will give you the Landau notation for your submitted solution (both in Time and Memory usage). I was wondering how they do that... How would you do it? Is there another way besides Lexical Analysis or parsing of the code? PS: This question concerns mainly PHP and or JavaScript, but I'm opened to any language and theory.

  • API Auth vs User Auth

    - by user1626384
    I have read many posts and articles on this topic but still cant connect the dots. I want to make a Rails app that is strictly a JSON API maybe using Sinatra or the rails-api gem. I also want to make both a web client app and an iPhone app which consumes the API. No plans on letting third party dev's use it. So I could create a separate username/password combination for both the web and mobile client and use HTTP Basic over SSL. Each app would have these values as configs in the source and use it to authenticate to the API so only these can make a call. Anyone else trying would get a 401 error returned. This would be considered handling the API authentication. The web and mobile client apps allow end users to sign up and read/write data to the API. When each user is created, I create and save a token in their profile. If a user successfully signs in, I send back the token. On each future read/write then also send along this token in the header. I get the token and lookup the user in the database and make the read/write. Does this sound like an appropriate way to handle it. For the web client, when I initially send back the token, where do I store it. In a cookie? Do I also drop a cookie to handle session state?
