• Security considerations when giving access to SQL Server db for a web application

  - by rem

  I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

• Filtering downloading a file

  - by Ozgun Sunal

  people. i know there are several types of firewalls operating at different layers of OSI. ACLs(layer 3 firewalls filter based on port numbers and IP addresses), SPI(which examines the patterns of data at layer 3 and realise that data content is malicious or not) and application layer firewalls which is capable of understanding the data at that level. Considering this, i'll give an example and learn what i need to do. Lets say, we have a computer has access to the Internet. i want to download a file or display a web page from a website but block access to the another website/s or downloading. To do this, i cant block access to the web browser on the 3rd party firewall bcos that will shut down all access. ACLs wont already do it. So, which kind of firewall will make it possible to filter specific traffic and how?

• Any way to tell apart a CPU defect from a mainboard defect?

  - by Pekka

  I have a fairly modern desktop computer, an AMD Athlon II X2 based silent PC, that does not work. When turned on, it will start physically (all fans are rotating, disks start up...) but not give a signal on any of the graphics ports (DVI, VGA, and HDMI, I tried all three). Also, the reset button does not seem to have any effect. I have stripped the mainboard bare of all SATA connections, extension cards, and the one 2GB RAM chip to eliminate them as the problem source, but to no avail, so I think it's fair to assume it's either the mainboard or the processor that are at fault. However, I have neither a replacement mainboard, nor a replacement processor handy to identify which one is broken. The cause of the defect is unknown, so for all I know, it could be both. Therefore, I'm reluctant to buy replacement hardware blindly before knowing more. Is there any way to further diagnose (or at least get some indication) which component is broken without buying replacement hardware?

• nautilus will not start, no right click menu, apps will not run due to 64bit libicui18n.so.48 overwritten with 32bit, ubuntu 12.04

  - by Dewb

  yeah so i broke my system trying to install support for 32bit apps. Somehow the 32bit set of libicu*.so.48 files replaced my 64bit files and now nothing works. I know what the problem is and how to fix it , what i need is some help. I need some kind soul running a 64bit install of Ubuntu 12.04 to simply go into their /usr/lib dir and copy the files that have the form libicu*.so.48* (8 of them i think, maybe 16 i dunno how many there is supposed to be since they were overwritten). Anyway if you could put those files in an archive, zip or tar preferred and then email/share the link. I was able to get these files installed but they're from the latest edition of fedora and while i can now use my computer , it's not that stable things don't start right smoothly every time like they used to .... and well its a simple ordeal to put things back the way they were if someone wouldn't mind helping out. also any help setting up the libraries related to 32bit apps would be great as well as i apparently screwed that up royally. Thanks for any help or advice

• Do I have a bad video card?

  - by zooropa

  I think this is the right spot to post this question. Please don't flame me if it isn't. My work computer is a Dell Prescision M6400 laptop. I use the VGA output to a second monitor. There is something wrong with my second monitor's output. Here is a screenshot of my desktop. You can see fragments of the right side of a Windows File Explorer window in the image. Is this a bad video card?

• Is there a word processor similar to MS Word which saves files as readable txt files?

  - by zenbomb

  I'm writing a paper together with my supervisor and would like to have a more sophisticated version control than *_291112_NEW_NEW_revised1.doc files. My supervisor is a non-computer person will never ever use LaTeX or git and loves MS Word. I'm therefore looking for an alternative to Word (I need commenting on text passages!) which stores the files as clean text (Markup for formating is fine), so I'm able to put them under version control on my side. I'm aware that git can also handle binary files, but I'd prefer the cleaner way of looking at the contents directly. If there's a way to automatically extract the text from word files, I'm fine with that too for now.

• VMWare Player disrupting Samba on Ubuntu 9.04 host?

  - by TonyUser

  I've had Ubuntu 9.04 running on this computer for a while now. I just installed VMWare Player on my system and now when I try to browse the network in the Ubuntu host all the computers will show up one time only. If I try to browse again, no computers appear and even the workgroup is missing. I have to run: sudo /etc/init.d/vmware stop sudo /etc/init.d/samba restart to get the network visable again. As long as VMWare Player is stopped Samba seems fine. I guess it's got to do with the virtual adaptors that VMWare installs. Is there a way to get them both to work, or did I just miss-configure something?

• Run a service after networking is ready on Ubuntu?

  - by TK Kocheran

  I'm trying to start a service that depends on networking being started, whenever the computer is rebooted. I have a few questions: Is this easily possible from an /etc/init.d script? I have tried creating a script here (conforming to the standards), but I'm really doubtful that it's even running on boot, let alone working. When I test it manually, it works. I've seen the new Upstart service, but as far as how that actually works, I'm completely in the dark. How can I make a script that runs on boot which runs after networking has been started? If I could run it after connected to wireless network, even better :)

• Having an issue with Java/ minecraft (Windows 7 64bit)

  - by MetroGnome

  I have had issues with java on my computer for a while. First of all, java has never worked on Google Chrome or Firefox, Only IE. Whenever I need to use Java, I use IE. Now, I just tried to play minecraft the other week and I receive the error "fatal error (1)" and get a black screen (this is on the online free version). Now, I searched for java and found that I have Java 32 bit. I cannot uninstall it on Revo uninstaller or Windows uninstaller. What should I do?

• How can I shrink my Windows partition further than the disk management is allowing?

  - by Walkerneo

  I just bought a new computer with a 2tb hard drive that has only a single partition. I would like to divide this into at least 4 partitions, but when I try to shrink the current partition, it says the total size is 1888171 MB and that the size of available shrink space is only 939075 MB. The used disk space is at 40gb right now - why can't shrink it to somewhere around that? I read here: http://www.howtogeek.com/howto/windows-vista/working-around-windows-vistas-shrink-volume-inadequacy-problems/ that this is because of unmovable system files. I doubt this is the only problem though. I would like to get this partition down to 500gb. How can I do this?

• Was Windows 95 an Operating System?

  - by shantnu

  This question maybe a bit historical, but we didn't have Superuser at the time. Around 2000 when I was starting my Computer science degree, a subject was Operating systems. The teacher asked us to list a few OS. I said Windows 95. I was immediately shot down. Windows 95 wasn't on OS, as it used DOS to boot up. The actual OS was DOS, Win 95 was just a graphical wrapper around it. I pointed that all trade magazines called Win95 an OS, but was told that they were run by laymen, and as a professional, I should know better. DOS was the only OS from Microsoft, at least till Win2K came out later that year. So 12 years on, I'm still not sure. Could Win 95 be considered an OS?

• How can I change the default keyboard layout in Ubuntu 10.10?

  - by startoftext

  Ubuntu keeps detecting my keyboard layout as Romanian. It almost always does this on a reboot and some times on waking from sleep. Some times it just randomly changes back to Romanian while the computer is on. I always set it back to "USA" in the keyboard preferences and delete the Romanian layout. What files configure this in Ubuntu? I looked in xorg.conf and did not find any keyboard settings. How can I set this to USA permanently? I have a laptop with a typical US layout built in keyboard and I also have an apple keyboard that is also US layout connected via USB. I have run other distributions on this same setup before and never had this happen.

• can't delete files on Windows 7 (permission)

  - by lajos

  I updated my laptop from XP to Windows 7. There are some leftover files from XP on the computer now, when I try deleting them I get an error: You need permission to perform this action. You require permission from S-1-.... to make changes to this folder. What's weird is that I am logged in with the only user account on this machine and I have administrator privileges. I tried turning UAC off, but still can't delete the files. How can I force removal of these files?

• Network-related icons suddenly removed

  - by Velcro

  Hello, On a fresh Windows 7 installation, I created some shortcuts icons to network shares on the Desktop. Without any warning, these icons are sometimes and randomly deleted from Desktop. I totally don't understand what it happens! They are not hidden, they just are simply deleted. This behavior occurs on one computer in my company. Others Windows 7 computers are not affected by that. And also it's the first time I encounter that. Do you have an idea about this problem? Thanks.

• Tunneling through SSH for 1521 port access?

  - by A T

  I am developing locally on my computer, using my own Apache server with PHP configured. My database however is remotely located on an Oracle 11g Database Server. We were also given a separate remote server for hosting our .html and .php files, however only FTP access has been provided there. Development is far too slow waiting for the FTP connection to push. So I decided to develop locally, but still use the remote DB server. Unfortunately that gives me an error. Not sure how—or where—to integrate tunnelling. Do I add something to the oci_connect HOST in my PHP file, or do I encapsulate my whole environment over SSH?

• Windows 7 - saved wifi access points disappear from list

  - by KáGé

  I'm having a weird issue with Windows 7 x64: I'm moving my notebook between two locations weekly, at each I have a wifi router. They both have hidden SSID-s, which are different. If I save one, the other one gets deleted from the list, as if overwritten, so I always have to retype the SSID and password, if I want to connect after moving my computer. At first I tought the problem was caused by both routers having the same password, but after I changed one (suffixed it with "_2") it persisted. What can I do about this? Thanks.

• What happened to WinFS?

  - by Console

  The most interesting feature that was ever connected to what eventually became Vista was WinFS, a revolutionary (so it seemed, at least back then) new way of storing and accessing information on a computer. This feature was cut despite actually reaching a closed alpha/technical preview release. There was a smoke and mirrors blog post from MS about the technology living on in an upcoming SQL server release, but to me it just felt like it was axed, hard. Does anyone have any idea what happened to it? Is it killed, or just on the backburner? Was it just impossible to implement, too expensive, or did someone think of a better idea? Are there any projects (From MS or anyone else) that have similar goals?

• How to enable winhlp on Windows7 64bit?

  - by BGM

  Salvete! I just discovered that winhlp32.exe won't run on Windows7 64bit. I can't run the application, and I can't run hlp files either (but .chm files run fine). How do I make this work? I have downloaded the Microsoft fix here and restarted my computer, but to no avail. I can see the file winhlp32.exe in my c:\windows directory, but cannot run it. When I do run it, I get Windows' own "Help and Support" entitled, "Why can't I get Help from this program?" which sends me to the link above! How can I make it work?

• ubuntu 12.04 will not play DVDs

  - by ayelet

  First off, I'm not just a newbie, I'm clueless! So your answers will need to be in complete idiot language (let's say I'm computer saavy, and I can follow directions,but I've never programmed anything and assume I don't understand any abbreviations. So why am I running linux? b/c windows was driving me nuts!! and my friend convinced me. day-to-day operations, we're doing fine, but when it comes to problems, I've got no clue what I'm doing!) So here's what's going on, my machine is an HP pavilion dv6, my optical drive is a standard cd/dvdrw, when i load an audio cd of any type (burned, official, etc,..) I have no problems, when I pop in a dvd - i get nothing. the dvd icon comes up in my launch tray, when I open VLC player I can find the dvd in the folder... but it won't play. I can watch movies I've downloaded with no problem, I can also watch movies off an external hard drive. The only thing I've tried is removing vlc and reinstalling, and I tried installing a different player (gnome maybe? I don't remember). none of that worked. Again, i can follow directions, but you need to be very specific and don't assume I know anything going in. (I mean, I know basic stuff, but nothing too technical.) PLEASE HELP!!! MY KIDS ARE DRIVING ME CRAZY!!! Thanks!!

• Set one homepage for all browsers simultaneously

  - by MorganTiley

  For testing purposes, I would like to set the homepage of all browsers installed on my computer — Internet Explorer, Chrome, Firefox and Safari — to the same page. I'd like to do this all at the same time. I imagine that there's an application that has an input box for the URL I want to use as homepage and an OK button to set it in all browsers. Where can I get a utility or script that can do this?

• How do i keep a newly started program from taking focus?

  - by Jugglingnutcase

  Say i'm coding in emacs and want to start up a music program. Because it takes too long to start up i go back to coding and type away. When the music application starts up, the focus is stolen (gasp! stolen!) away from emacs and goes to the music application, often mid-thought. Is there any way to keep this from happening and have the newly started application not have focus until i see that it's up and ready to be used? Besides getting rid of my ADD of course. Or getting an impossibly fast computer that can keep up with my mind. i'm using a Windows XP system, but i will soon have a Windows 7 system, and i have Linux at home.

• Automatic profile load on boot

  - by AnthonyW

  Is there any way to configure a computer to login automatically at bootup and then IMMEDIATELY switch users? The purpose is to trigger the profile loading process for the assumed user so that when they go to login, their profile loads instantaneously. Yet, the immediate user switch means that the login password is still required before any actual use. A few of the attempts I have made require storing the password in plain-text for the system to use. Needless to say that is undesireable. I have been looking for this solution for years; if anyone knows of a better solution to skinning this cat I am all ears. EDIT: tsdiscon command will Lock the workstation.

• Does a dedicated video card improve HTML5 websites, Skype or Flash games performance?

  - by Kiewic

  I have read that having a dedicated video card (GPU) improves performance if you use your computer to play video games. I guess to make this happen, video games or apps must be using especial libraries designed to share the workload with the GPU, maybe Direct X or OpenGL, I don't know. Am I wrong? So, can HTML5 websites, Adobe Illustrator, Flash games (Zynga games), Skype or Netflix benefit from a dedicated video card? I usually do the previous activities simultaneously. Should I consider changing from an integrated video card to a dedicated card if I want to improve performance? Thanks.

• How to compile gcc-4.0 on Mountain Lion

  - by Frizlab

  So far I've successfully launched the configure, but when I type make, I get the following error, after some time (there's a lot which compile successfully): ld: unknown/unsupported architecture name for: -arch i686 /usr/bin/libtool: internal link edit command failed make[2]: *** [libgcc_s.dylib] Error 1 make[1]: *** [libgcc.a] Error 2 make: *** [all-gcc] Error 2 Is there a way to tell gcc not to compile itself for the i686 architecture?

• Update-manager fails silently on 14.04

  - by pabuisson

  I recently reinstalled a lubuntu from scratch, to upgrade to 14.04. Everything's working as expected, except for the update-manager that silently fails when trying to upgrade my system's packages. It does correctly list the packages to be upgraded, I can then click on the "Install now" button (or something like this, I'm running a French flavour of Ubuntu). When I click the button, it seems unresponsive for 5 to 10 seconds, then the upgrade dialog with the progress bar appears, displays "Loading package list", then very shortly something about "authentication" (not long enough so that I can read it).. and closes. The install is fresh and I have no idea where to look. I tried launching update-manager in a term but it doesn't display any error when it fails, only this message when the window first shows up : ** (update-manager:3642): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-m0jkFlZ3yo: Connexion refusée. Any idea where this might come from ? I can upgrade the packages using the command line and sudo apt-get but this is not my computer, and I do not wish its owner to have to do this to upgrade the packages. Thanks for your help !
