• RDC not working from outside

  - by Cotten

  I've set up Remote Connection according to : http://windows.microsoft.com/is-IS/windows7/allow-remote-desktop-connections-from-outside-your-home-network That is, Allow remote connections to the computer you want to access. Make sure Remote Desktop is able to communicate through your firewall. Find the IP address of the computer on your home network that you want to connect to. Open your router's configuration screen and forward TCP port 3389 to the destination computer's IP address. Find your router's public IP address so that Remote Desktop can find it on the Internet. When I'm inside the LAN, RDC works flawlessly. When I try to connect to the ip given by my ISP it cannot connect. I've setup port forwarding for 3389 on my netgear router. Thanks!

• How can I disable the prefetch cache?

  - by Oli

  I run a few Ubuntu servers that have a load of django sites running on them. The sites and the httpd start at boot and after that (apart from me SSHing in to update it or using bzr to update websites) nothing else gets run on it. At the moment over half the ram is allocated as cache. This isn't a problem because cache usually makes space or a little bit of it slips into swap (again, this doesn't really bother me) but I don't see the need for it. Is there a quick way to disable the cache? This is more of an experiment than anything else so it would be handy to know how to turn it back on again.

• LDAP authentication: Windows Server2k3 vs. 2k8

  - by wolfgangsz

  We have around 70% linux users, all of which are configured to authenticate against Active Directory through LDAP. In order for this to work, we used the "Windows Services for Unix" under Windows Server 2003, and it all works fine. We are now at a point where the server running this contraption is getting a bit tired and will be replaced with a newer machine, running Windows Server 2008 (where the relevant services such as user name mapping and password changes, etc., are integrated with the OS). And here's the rub: If a new user is configured through the Win2k3 server, then it all works fine. If the same thing is done through the Win2k8 server, then : The ADS plugin on the 2k3 server does not recognize it and behaves as if the UNIX attributes were never set. The user cannot authenticate against ADS using LDAP. Has anybody encountered this problem? If so, how did you overcome this? If you need any additional information to provide further help, just ask and I shall provide it.

• How to make a minimal upgrade?

  - by wajed

  I use apt-get install --no-install-recommends ubuntu-desktop to install minimal desktop. I want to upgrade my system to the latest version (12.04) with it still being minimal. How do I do that? What I tried:- I tried Update Manager, and it gave me the Option to upgrade to 11.10 first, then to 12.04. What happened after I upgraded to 11.10 is that my desktop got bloated, and instead of the system using 500MB of RAM, now it uses about 1.5GB I can't even start apps anymore.

• Drupal 7 on Windows - File Module Problems

  - by TimothyP

  Installed Drupal 7 using the Web Platform installer on Windows 2008 For some reason, the file module, when you upload a file, uses the first few letters of the filename as the unique key to store in the database, which of course causes problems very fast. I'm wondering does anybody have a workaround for this? An AJAX HTTP request terminated abnormally. Debugging information follows.

• No desktop after installation of nvidia drivers

  - by hovmand

  I have a problem very similar to this guy: Desktop does not show when I installed nvidia drivers!. I have the same problem with the desktop not being present when I install choose the nvidia drivers from the software sources dialog. I've trie the answer mark as the solution, but this doesn't help me. Still get the same result / bug. I've also tried just to reconfigure it, like this guy says: http://ubuntuforums.org/showpost.php?p=12303179&postcount=4, but that didn't help me either. Then someone suggested that I should try Bumblebee. I followed the installation (https://wiki.ubuntu.com/Bumblebee#Installation) and after the reboot the resolution was still crappy, but this time the desktop did show up, but with bad graphics and I couldn't use optirun and it turned out that bumblebee couldn't start. I hope someone might know whats wrong or what I'm doing wrong. I have a Lenovo W520 with a nvidia Quadro FX 880M and I'm running ubuntu 12.10

• BSODs after Windows 8.1 Upgrade

  - by Techrocket9

  I just upgraded my system to Windows 8.1, and I have been getting BSODs that I did not get before the 8.1 upgrade. Though I cannot conclude that running the Android Emulator with Intel's HAXM is the cause, both crashes have occurred while the emulator was running. I get CRITICAL_STRUCTURE_CORRUPTION, the same error as this guy, except I don't have the hardware/software that he has that caused his problem. Minidumps here. Output of verifier.exe /all and then a reboot and then verifier /query: http://sdrv.ms/17CPVu9 Edit: According to software.intel.com/en-us/forums/topic/475129 (can't link due to lack of rep) it is being caused by HAXM. Will close question when I find a solution.

• Do I need to recompile PHP to make use of CURL API?

  - by amn

  I have both Apache and PHP set up manually, albeit the latter without CURL. There is this jungle of instructions and explanations on extensions for PHP. I have a very straightforward question - what do I need to do to enable CURL in a more dynamic way. I resent the idea of static linking, in fact I hate and avoid static linking like the plague. Is it possible to have my Apache and PHP understand that there is CURL in town? I can compile CURL if necessary. Package management may be out of the question, because I built PHP myself - I am on Ubuntu, and it does not provide PHP without Suhosin and a a whole lot of time, so I removed it and built PHP myself. The whole slew of related questions simply propse installing "php5-curl" package, which is exactly one thing I CANNOT do since it installs it in a completely unrelated directory, which my PHP does not even seem to bother linking to.

• Chrome tabs showing wrong page

  - by Jeff

  I have a problem with Google Chrome where occasionally when switching to a newly created tab (usually one made from opening a link into a new tab), the wrong page shows. The correct page is functional, links and other functions are present, but I cannot see them because Chrome seems to be reading the page I want but showing another. Sometimes it is identical to the tab I just left, sometimes it shows the content of a previously closed tab. The problem sorts out when I switch to another tab and back, and then the correct page shows. This happens fairly often and is rather annoying. Some of my friends have also experienced this, and have stopped using Chrome because of it. If anybody else has seen this problem and happens to know a fix, I'd really appreciate it.

• What's the difference between "Service" and "/etc/init.d/"?

  - by Marco Ceppi

  I've been managing server installations both on and off Ubuntu flavor for some time - I've become quite adjusted to /etc/init.d/ for restarting servcies. Now I get this message: root@tatooine:~# /etc/init.d/mysql status Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service mysql status Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the status(8) utility, e.g. status mysql mysql start/running, process 14048 This seems to have been brought about in the latest LTS of Ubuntu - why? What's so bad about /etc/init.d/ and what/is there a difference between service and /etc/init.d/?

• IIS 7 with PHP in Domain with Windows Authentication

  - by Michal Saiyan Hajdony

  I have Windows Server 2008 R2 x64b installed with IIS 7, PHP 5.5. This server is added to domain exampledomain , so I have win authentication enabled and all others disabled. I left the two default providers NTLM and negotiate, I granted IIS_IUSRS read access to wwwroot. So far it has worked for me only as I am added to the Administrators group which has read/write access to wwwroot folder. Yet, when someone else is trying to connect, he gets a credentials window and when he puts the domain name and password he cannot get access to the page. The issue is solved when I add read permission to "Domain users" - then all works fine. BUT. My issue is that if one opens windows explorer and types \\servername\wwwroot one can see the files and read them. I have never configured IIS before so I know I miss some really important thing. How can I solve the file visibility problem?

• EXEC() syntax error using ODBC

  - by Mike Trader

  I have written a little ETL application that I wish to run a few lines of TSQL from. If i enter a simple query like "SELECT * FROM MyTable" everything is fine. All single line commands run as expected. A multiline query like this is also fine: DECLARE @TableName NVARCHAR(MAX) set @TableName = 'MyTable' EXECute ( 'DROP TABLE '+ @TableName ) Howevery when I try and run: DECLARE @TableName NVARCHAR(MAX) OPEN Tables FETCH NEXT FROM Tables INTO @TableName WHILE @@FETCH_STATUS = 0 BEGIN EXEC( 'DROP TABLE ' + @TableName ) FETCH NEXT FROM Tables INTO @TableName END I get a syntax error after TABLE in the EXEC() call. I have spent 6 hours trying to figure this out thinking perhaps I need to escape the single quote or something. I just cannot see the problem. A set of fresh eyes would be appreciated.

• What is the benefit of the "download will begin shortly" page?

  - by Fammy

  I've noticed many websites that host files for downloads have an interstitial page between the download link/button and the actual start of the download. Terminology on the page may include "Your download will begin shortly. If it does not, try this direct link". What is the purpose of this page? It seems to draw away from the general experience of downloading a file. Is this beneficial for bookmarking? Less experienced users? Analytics?

• LDAP replication breaking referrals

  - by MasterZ

  We have an issue that we believe is caused by ldap replication changing the port of the referal from 686 (secure) to 389 (unsecure). If we setup a new referral everything works, but then as soon as we change someone's password it changes on the master, and then the master replicates and the referral breaks. Any further attempts to modify someone's account give the error "PAM: Cannot connect to LDAP". We used snoop and monitored the firewall to see what was going on. The first password attempt (the one that works) goes over port 686 (as it is supposed to) but every subsequent attempt attempts to use port 389, and therefore fails. We only have 1 referral configured on the client, port 686

• dig gets the right result from DNS server, but name still fails to resolve

• ACPI Events not triggered after booting

  - by user3208188

  I purchased a Convertible (Laptop and Tablet, Ubuntu 14.04 installed) and would like to execute a script when changing from laptop to tablet mode and the other way around. So I created two new files within the /etc/acpi/events folder corresponding to two new scripts in the /etc/acpi folder. Everything works well if I create a new acpid process (e.g "sudo acpid -c /etc/acpi/events -s /var/run/acpid.socket") manually. However, if I do not initiate this process manually the scripts are not executed, even though there is a process running with the same options right after the machine has booted by default. The only difference I can find is the parent pid. If I create the process the parent is "init --user", while the parent of the automatically initiated process is "/sbin/init". Can anyone help me by explaining why this issue happens and how I can avoid to start an acpid process manually every time I boot the device?

• Nullable types and ?? operator C# [en-US]

  - by ruimachado

  Nullable types vs Non-nullable types   While developing our C# projects its frequent the null comparison operation to avoid null exceptions. This simple operation is mainly coded using the "var x = null" code example inside an if clause. However not all types of variables are nullable, which means that setting a variable to null is not allowed in every cases, it depends on what kind of type are you defining. But what if there was an extension to your non-nullable type that would convert your variable types to nullable? This extension really exists. As I said before in C# you have nullable types which represent all the values of an underlying type, and an additional null value and can be declared easily using "T?", where T is the type of the variable and for example the normal int type cannot be null, so its a non-nullable type, however if you define a "int?" your variable can be null, what you do is convert a non-nullable type to a nullable type. Example: int x=null;     Not allowed     int? x=null;   Allowed     While using nullable types you can check if a variable is null the same way you do it with nullable types:     But what about setting a default value when a certain variable is null?   In this cases the c# .net framework let you set a default value when you try to assign a nullable type to a non-nullable type, using the ?? operator. If you don't use this operator you can still catch the InvalidOperationException which is throw in this cases. For example  without the ?? operator :     Using the ?? operator your code becomes cleaner and more easy to read and you get a bonus, you can set a default value for multiple variables using the ?? in a chain set.     That’s it,   Thanks, Rui Machado rpmachado.wordpress.com

• suddenly can't connect to Windows 7 PC from xbmc

  - by Damon

  I have xbmc installed on a softmodded classic xbox and all of a sudden I cannot connect to the shared folders on my Windows 7 PC. Well, it can connect but it wants a username and password, but none exist on my computer. It's been several weeks since I last used it, but it was working fine then! and no particular changes I can think of aside from I guess a few Windows updates. I've seen reference online to Windows Live essentials causing issues with file sharing, but I don't even have that installed. And I made sure to tick 'turn off password protected sharing' in my advanced network setup. I had the guest account turned off and working fine before, and tried turning it on but no luck. I can access my shared folders fine from other Computers and a ps3. I've read a couple threads of similar situations on various folders and none of their solutions have worked.
