• Ubuntu: On a network with many clients there are two machines that can't access the web via a browser at the same time

  - by ChrisInCambo

  Ok I'm pulling my hair out over this one. We have a wireless network with many clients all working well except two Ubuntu clients running 10.10 that can't access the internet via a browser at the same time. They can both still ping, use Skype etc but can't browse. As soon as the one that can browse exits the network browsing returns for the other and vice versa. As ping and Skype was working I assumed some kind of DNS problem but moving over to OpenDNS didn't solve it, nor did restarting networking or using wired rather than wireless. We also switched out the router, and it still persisted so I'm sure this isn't a network issue. The two clients are both laptops and work fine together on a wireless network at another office (which we don't control). I'm thinking something must be cached from the other network they both use that's causing this but have no idea what. Does anyone have any ideas? I just don't know where to go from here.

• Cannot start IIS on XP64 Professional

  - by headsling

  I have enabled the iis components for the first time on this machine, from control panel-add software-windows components, and rebooted. When I attempt to start the "Default Web Site" (which shows as 'Default Web Site (Stopped)' ) from inetmgr nothing happens.. no errors, nothing in the event log. Regmon and Filemon show no obvious errors. I've confirmed that nothing is running on port 80 and have tried changing the local port (8080, 8081 etc.,) with no effect. Further info -- I have removed the install, rebooted, added it back in, rebooted ... still not working. I have visual studio 2008, SQLServer 2008 installed.

• Mouse pointer size inconsistent

  - by charon00

  Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

• How to emulate a domain name - Webmin Setup

  - by theonlylos

  I am currently working on a client project where they are using a custom CMS which relies on having the specific domains configured for it to work properly. So in English, that means that when I try running the site on my test environment, the entire website fails because it isn't located on the primary domain (and I'm pretty sure the domain is hard coded since there's no control panel to adjust the file locations). Anyway what I wanted to ask is whether it is possible to use my test environment URL but have Apache and the DNS emulate my clients website URL locally, rather than calling the actual name servers. Right now I have a virtual host setup in Apache but I am not sure where to go from there. Any assistance is greatly appreciated.

• Is it reasonable to null guard every single dereferenced pointer?

  - by evadeflow

  At a new job, I've been getting flagged in code reviews for code like this: PowerManager::PowerManager(IMsgSender* msgSender) : msgSender_(msgSender) { } void PowerManager::SignalShutdown() { msgSender_->sendMsg("shutdown()"); } I'm told that last method should read: void PowerManager::SignalShutdown() { if (msgSender_) { msgSender_->sendMsg("shutdown()"); } } i.e., I must put a NULL guard around the msgSender_ variable, even though it is a private data member. It's difficult for me to restrain myself from using expletives to describe how I feel about this piece of 'wisdom'. When I ask for an explanation, I get a litany of horror stories about how some junior programmer, some-year, got confused about how a class was supposed to work and accidentally deleted a member he shouldn't have (and set it to NULL afterwards, apparently), and things blew up in the field right after a product release, and we've "learned the hard way, trust us" that it's better to just NULL check everything. To me, this feels like cargo cult programming, plain and simple. A few well-meaning colleagues are earnestly trying to help me 'get it' and see how this will help me write more robust code, but... I can't help feeling like they're the ones who don't get it. Is it reasonable for a coding standard to require that every single pointer dereferenced in a function be checked for NULL first—even private data members? (Note: To give some context, we make a consumer electronics device, not an air traffic control system or some other 'failure-equals-people-die' product.) EDIT: In the above example, the msgSender_ collaborator isn't optional. If it's ever NULL, it indicates a bug. The only reason it is passed into the constructor is so PowerManager can be tested with a mock IMsgSender subclass.

• External monitor on old Dell 700m?

  - by Adam Henne

  Okay, linux noob. I installed 10.04 on an old Dell 700m in hopes of using it as a media center device. That seems to work great, except now it won't output to the external monitor. VGA cable works fine, TV recognizes other computers fine, it's the laptop that won't output. Turns out that the 700m, unlike every other computer out there, doesn't have a Fn hotkey to switch monitors. The only way to do it in Windows was to go through the Control Panel. In Ubuntu, though, the Monitor setup won't detect or recognize any monitors. The laptop display works fine, but I can't adjust or add anything. I did a little research and found suggestions for older Ubuntu builds involving the xorg.conf. I tried one out, in spite of my unfamiliarity, and it's screwed the whole display big time. I can fix that with a clean reinstall, that's no problem, but I'm cautious about editing xorg again. Any suggestions? Thank you!

• SQL Server 2005/2008 Licensing Decision

  - by Hakim

  Hello, I have purchased a dedicated server from a reputable Hosting company. They only have Windows Server 2008 OS installed on it and NO Sql server. Server Configuration is Intel Dual core Processor with 2GB of RAM and 100GB HDD. I wanted to host my web services on that server which will be using the MS SQL Server 2005 at the backend.There are multiple web services and each using a different Database. Microsoft has CAL basis Licensing , Which I understand is based on number of users accessing the database directly ( I may be wrong ) . But my users will be accessing the webservice and no direct connection to the database as such. Yes but the number of users accessing the web server cannot be known and is not under my control. Which Licensing is best suited for this kind of setup ? I don't need analysing and BI services right now ,but i may want to upgrade that in future may be. Any help will be appreciated. Thanks

• Laptop forgets second monitor when it goes to sleep

  - by al c

  I recently updated my nvidia driver... now I have to re-establish the connection to my second monitor everytime the laptop goes to sleep. When I open the NVIDIA control panel, the second monitor is listed there but the checkbox beside it has been cleared. Oddly my laptop screen is identified as display #3 and the external screen as display #4. Is there a registry key that I can clear to get them set back to #1 & #2? Will that fix the problem? Or is there a simpler solution. (It's a Dell Studio XPS laptop with GeForce 9500M running Windows Vista 64-bit) TIA Al

• Build Advise for Home Web/NAS Server with Ubuntu Server 12.04 [closed]

  - by razor7

  I need to have a personal Webserver with NAS capabilities. The Webserver to test some LAMP projects I develop for clients, and also NAS to be able to stream media to local network. I want to have full control of the box, so I'm planning to build it with some spare parts and Ubuntu Server. The services/software that will run are (remember, is for personal and testing use only): SAMBA/CIFS SSH Server Apache 2 MySQL 5 Mercurial Repo PHP 5.3 Ruby on Rails OwnCloud Dovecot Webmin Postfix PureFTPd ClamAV The Hardware: Intel Dual Core E2180 2.0 GHz MSI P35 Neo Kinkston 1GB DDR2, 667 MSI Nvidia 7300le PCIe x16 256mb RAM HDD SATA WD Green 2TB x2 (RAID-1 with MDADM RAID Controller) 16 GB USB Pendrive (For server system installation) My idea is to build this system, using the pendrive for the Ubuntu Server software, and packages, and the RAID-1 for gross data storage. What do you think? Thanks a lot!

• Optimize Windows file access over network

  - by Djizeus

  At my company I frequently need to access shared files over a Windows network. These files are located on the other side of the planet, so I guess the file share goes through some kind of VPN over Internet, but I don't control this and it is supposed to be "transparent" for me. However it is extremely slow. Displaying the content of a directory in the file explorer takes about 10s. Even if over the Internet, I did not expect that retrieving a list of file names would be that long. Are there any settings to optimize this from my Windows XP workstation, or is it mostly related to the way the network is configured? The only thing I have found so far is to cache all file names, while by default only short file names are cached (http://support.microsoft.com/kb/843418).

• Security Issue with Active Directory

  - by Will McCloskey

  The retard who was on the built-in Administrator login somehow (and this is what I'm guessing being as he is not here and I was not present when this occurred - Supposedly it was an "ACCIDENT") Denied the built-in Administrator account and every other account except for his personal one access to our domain - ie "Example.net" not just active directory or anything. I've been trying for literally 2 hours to find some sort of way to take control of the domain through the built-in Admin account with no success; I can't even open Active Directory. I'm not aloud to open DSA.MSC and there's no way for me to take ownership. Any ideas?

• Ubuntu Studio 10.4 boots to terminal mode only

  - by Don

  I did clean install from ISO DVD. It boots only to command line asking for login. After I login I enter STARTX and desktop appears and some of the studd actually works, but there are a lot of problems: there is no way to reboot or shut down except to stopx/logoff and enter shutdown sound system doesn't respond pulse audio volume control gives "connection failed, connection refused" DVD drives not available GDebi Package installer is grayed out and so I can't use it (but synaptic package manager works OK) Software Center won't start when clicked -- it just stops trying DBus cant run because it says /usr/local/var/run/dbus/system_bus_socket file not found (also /var/run/dbus/system_bus_socket file not found) There's just a lot of things wrong and I can't help but think something is missing or was mis-coded in the distro so that there are typos in some script somewhere. If anyone can tell me where to begin to untangle this mess I'd appreciate it, but I think it all begins when it can't start the GUI automatically and I need to enter STARTX.

• Is it possible to keep only one Database for both web and desktop applications?

  - by B4NZ41

  I'm experiencing a trouble with my business model, let me explain better. I'm developing a software for 1 year and few months, it's for the food industry, more exactly a software to: Delivery, Take Way, Table Reservation, POS, Accounts Payable and Receivable, Prints(receipt), Kitchen Monitors Orders, Customers Orders Control and Fiscal Area. Well, I had separated the software mainly in two areas, one is web area and the other is desktop area (Used by Admins only) and local installed. 1 - Web Area (Basically do the follow:) Show Catalog with the products Customers Make Orders Customers Pay for the Orders etc ... as mentioned above 2 - Desktop Area Manage Orders Manage Customers Manage Suppliers Manage Accounts Payable and Receivable etc ... as mentioned above The web area is hosted in an online web server (scripts and database are online). The Desktop area is hosted locally in a Linux machine with a local database and local scripts files. My question is: Is it possible to keep only one Database for both applications? If YES, please what is the best approach? Follow my technical specification environment Database: Actually I have two databases working and I would love to keep only one. Operating System: Linux (Kernel 2.6.X and above) or Windows (XP and above) For the Web Area Apache, PHP, Python, Java Script, Shell Script and MySQL. For the Desktop Area: PHP-GTK2, Apache, PHP, MySQL and Shell Script.

• Beaglebone Black running Debian, does device tree overlay act as an api?

  - by user3953989

  This maybe more of a Linux specific question but... I've been reading many tutorials and it seems that you can use JavaScript, Python, and C++ to write code for the Beaglebone Black(BBB). It looks like the way C++ interfaces with the BBB hardware is via reading/writing text files on the OS while Python has it's own library. All the C++ examples out there control the GPIO and PWM via reading/writing to text files. Is this the only way to access the hardware or just how Linux does drivers?

• How to restrict deletion of a folder on NTFS share, but still allow modify access within folder

  - by thinkdreams

  I am setting up a set of scan folders from a scanning copier device, and would like to know the best way to protect the folders (for each department) from moving or deletion, but yet still allow access for the users to modify (i.e. create/add/delete) the scanned files within the folder. Structure is: Share Name Departmental Folder User files The writing of the files initially is taken care of by a service account which has full control. We'd just like to ensure the users cannot accidentally delete the folder (which has already happened) containing all the files, etc. This is for a Windows 2003 server, NTFS permissions. Suggestions would be most appreciated.

• Server 2008 R2 file access permissions

  - by Napster100

  I'm finding it awkward to sort out permissions for file sharing and access on my LAN. I've created an account on the server node (as a normal user) and shared a drive that has 2 folders at the root, one is for personal file storage and the other shared files, if I connect to the shared area from a workstation running windows 7 and log-in using the account I created on the server, I can look through directories but can't look in some (which I wanted as I changed the permissions for that to happen), but my problem is although the permissions are set for this user account to have full control of the specific folder I can't create a folder in that area or upload files to that folder. Could someone explain why this is? Thanks in advanced

• Windows 8 Permissions

  - by Dane Balia

  I, 2 days ago, completed a standard Windows 8 installation. It was a fresh install, however Windows 7 was on the disk prior to which it migrated to Windows.old. But for some strange and weird reason, I am struggling to 'write' to my disk in regards to .NET Applications. It appears that none of my .NET (self-written) applications can write to their log files on disk, which are created on startup. I have disabled UAC, as well as set Full Control over Disk C: for my User, but no luck. I keep getting the error: A required privilege is not held by the client. I did google and try some online tuts - but no luck! Thanks

• Domain controller policies having administrative issues with program installations

  - by russ

  I have an issue with our domain and policies where a user needs administrative rights to install a program and someone provides the credentials for the 'run as admin' or 'run as other user' it will always show an error: Cannot find specified file on the drive. So we cannot install programs for our employees. How I fix it is I add the user to administrators, force a policy update, have them reboot, run as administrator and install it that way. Then remove them after and update the policy. Another way was to right click the install file (.exe/.msi) and add the user and administrator as an owner with full control. Only works when we have the installation file. I have no idea how to fix this and I can't find a relevant thread or QA about this problem. I can only find users having issues on their home computers not on a domain. Any help and threads to read would be great!

• Pop current directory until specific file is found

  - by edarroyo

  I'm interested in writing a script with the following behavior: See if a file, build.xml, exists in the current directory, if so run a command supplied through arguments to the script. If not, pop the current directory and look at the parent. Go to 1. The script would end once we find the file or we reach the root. Also, once the script finishes and control comes back to the user I want the current directory to be that one where the script was initially l I'm not very familiar with shell scripting but any help/guidance will be much appreciated.

• What's the benefit to learn Java programming?

  - by user30139

  I'm from the PHP world. Recently I'm trying to learn about Java. Because simply I'm a bit interested in Android development. Learning about Java gives more control about my cellphone. Say I could fine tune some applications to fit my personal requirements or even make my own ones. Still Java is a new world to me. I guess I'm already too comfortable with weak typed languages such as PHP. Honestly I think application development of no matter which kind wouldn't make too much difference. Because just as web development mostly framework based, what the developer do is to fill the blanks meaning to follow the protocols the given by the framework. Most of the code is still about business logic, that's what application development all about, right? The big difference seems to lie on the programming languages. Comparing to PHP, Java holds a whole package of constraints and practices. At this point, what are the benefits to learn programming in it?

• Suggestion for live video stream aggregation/switching/forwarding/management software?

  - by deceze

  I'm looking for a software or system that can receive video streams from a number of cameras via a network (RTMP or similar protocol), present a visual overview of all video streams and allow me to forward/send a selected stream to another service (e.g. to a Flash Media Server, or anywhere via RTMP). Basically the digital internet equivalent of a TV studio control panel, which allows a director to put together a live show. Is there any such software at an affordable price? A GUI-less server which can be scripted to switch streams would be good too. I'm not even quite sure what kind of product category this falls into or what search terms to plug into Google. Most results I have come up with have little more than an executive summary description which doesn't tell me anything. Any suggestion welcome.

• Do all domains on the same shared hosting server have the same IP or ID

  - by silow

  Here's what I've got: siteA.com and siteB.com are hosted on hostgator. They're hosted on the same account of a shared hosting server (not VPS or dedicated). script.php is an external site that each of these 2 sites are accessing. I noticed that when siteA.com or siteB.com access the outside script.php, the script identifies them both as 1a.12.12ab.static.theplanet.com (apparently because hostgator uses theplanet.com servers). The fact that they're identified as the same value isn't surprising because after all they're hosted on the same account /home/user123/public_html. What I'm wondering about is how about other websites that are hosted on the same shared hosting server, but under other accounts. Basically other websites that are under another developer's control, but just happen to share the same hardware (hosting server). Do they also have the exact same identifier 1a.12.12ab.static.theplanet.com or that changes by account?
