• SQL SERVER – FIX ERROR – Cannot connect to . Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452)

  - by pinaldave

  Just a day ago, I was doing small attempting to connect to my local SQL Server using IP 127.0.0.1. The IP is of my local machine and SQL Server is installed on the local box as well. However, whenever I try to connect to the server it gave me following strange error. Cannot connect to 127.0.0.1. Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452) The reason was indeed strange as I was trying to connect from local box to local box and it said my login was from an untrusted domain. As my system is not part of any domain, this was really confusing to me. Another thing was that I have been always able to connect always using 127.0.0.1 to SQL Server and this was a bit strange to me. I started to think what did I change since it  last time I connected to SQL Server. Suddenly I remembered that I had modified my computer’s host file for some other purpose. Solution: I opened my host file and immediately added entry like 127.0.0.1 localhost. Once I added it I was able to reconnect to SQL Server as usual. The location of the host file is C:\Windows\System32\drivers\etc. You will find file with the name hosts in it, make sure to open it with notepad. If you are part of a domain and your organization is using active directory, make sure that your account is added properly to active directory as well have proper security permissions to execute the task.

• How does Google Friend Connect accomplish cross domain communication without needing to upload a file to the client domain?

  - by mboyle

  Previously, Google's Friend Connect required users to upload a couple of files to their websites to enable cross domain communication and Facebook Connect still requires you to upload a single file to enabled it. Now, Friend Connect doesn't require any file upload... I was wondering how they were able to accomplish this.

• How do I connect to Ubuntu One after changing the password?

  - by rumtscho

  I changed my password for Ubuntu One using the Web interface, and added a new computer. Since then, the old computer does not synchronize with Ubuntu One. It doesn't show any error messages or such, but files uploaded from the web interface or changed on the newly added computer don't appear/change on the old computer. I guess that it can't connect because it is still using the old password. The problem is that I can't find an interface to change the password the client is using to connect to the service. The "manage account" option opens the Web interface. I looked into the keyring, and found the key for Ubuntu One, but there I only see an encrypted version of the password, so I can't change it there. So what is the correct way to tell my client that my account password has changed? Edit this is what I see when I open Preferences -- Ubuntu One. Is there something wrong with it? It also stubbornly insists that it has successfully synchronized. But the files I have added from other computers are not in my Ubuntu One folder.

• How to reference or connect a variable to another class without stack overflow?

  - by SystemNetworks

  I really need to re-arrange all my functions. I created a class. All my var, booleans, int, doubles and other things. I created every new variable so they can reference it and so they don't have an error. If your asking why I never just reference my main class vars to my sub-class becuase it will give me stack overflow! When in my main class i link my sub-class. subClass s = new subClass(); Then I reference my fake variable to my real variable for example: This is my sub-class variable(I call it fake) public int x = 0; In my main class, I put it like this: s.x = x; The problem is, it does not work! Maybe this is not the right place but I cant ask any questions on stack overflow because they banned me. If I connect my main class and connect my sub-class it will give me stack overflow. How do I stop it?

• Exceptions from automongobackup, yet script completes

  - by chakram88

  I am using automongobackup to, well, automate the backups of mongodb. output from the script (to STDERR) has the following exceptions (but the backup completes, and the dump files are created) ###### WARNING ###### STDERR written to during mongodump execution. The backup probably succeeded, as mongodump sometimes writes to STDERR, but you may wish to scan the error log below: exception: connect failed exception: connect failed exception: connect failed exception: connect failed exception: HostAndPort: bad port # exception: connect failed exception: connect failed exception: connect failed exception: connect failed exception: connect failed exception: connect failed I know that the Host & Port are correct. If I run mongodump --host=127.0.0.1:27017 --journal (which is the effective command from automongobackup based on the options set and my reading of the src code) everything runs clean without any error reporting and the dump files are created as expected. Why would automongobackup report connection errors, even tho it does create the dump files, yet a straight call to mongodump does not? Debian 6.0 Lenny (from Linode image: Latest 3.2 (3.2.1-x86_64-linode23)) AutoMongoBackup VER 0.9 mongodb v 2.0.2

• PHP] How can I connect to MySQL on wamp server?

  - by user294359

  This might be ridiculously easy for you.. but I've been struggling with this for an hour.. :( <?php $connect = mysql_connect("localhost:8080", "root", "mypassword"); echo($connect);?> This is the code that I'm trying to run - you can see that I'm using 8080 as my port number and, of course, I have html codes as well. However, it gives me the following error msgs whenever I try to open the php file. ==================================================================================== Warning: mysql_connect() [function.mysql-connect]: MySQL server has gone away in C:\wamp\www\php_sandbox\index.php on line 2 Warning: mysql_connect() [function.mysql-connect]: Error while reading greeting packet. PID=4932 in C:\wamp\www\php_sandbox\index.php on line 2 Warning: mysql_connect() [function.mysql-connect]: MySQL server has gone away in C:\wamp\www\php_sandbox\index.php on line 2 ===================================================================================== I don't know... what's wrong with this. Is it because of the port number?

• How to interrupt a thread performing a blocking socket connect?

  - by Jason R

  I have some code that spawns a pthread that attempts to maintain a socket connection to a remote host. If the connection is ever lost, it attempts to reconnect using a blocking connect() call on its socket. Since the code runs in a separate thread, I don't really care about the fact that it uses the synchronous socket API. That is, until it comes time for my application to exit. I would like to perform some semblance of an orderly shutdown, so I use thread synchronization primitives to wake up the thread and signal for it to exit, then perform a pthread_join() on the thread to wait for it to complete. This works great, unless the thread is in the middle of a connect() call when I command the shutdown. In that case, I have to wait for the connect to time out, which could be a long time. This makes the application appear to take a long time to shut down. What I would like to do is to interrupt the call to connect() in some way. After the call returns, the thread will notice my exit signal and shut down cleanly. Since connect() is a system call, I thought that I might be able to intentionally interrupt it using a signal (thus making the call return EINTR), but I'm not sure if this is a robust method in a POSIX threads environment. Does anyone have any recommendations on how to do this, either using signals or via some other method? As a note, the connect() call is down in some library code that I cannot modify, so changing to a non-blocking socket is not an option.

• My Encore N300 wireless usb doesn't connect, any workarounds?

  I decided to wipe Windows 7 and made a full installation. Everything works great but for a Encore N300 wireless usb dongle that I use on my desktop. Ubuntu seems to recognize it and I can browse the available networks, but I can connect to any of them. I was told that I should download its drivers, and so I did it, but I don't know how to install them. Please, I'd like to know if my connectivity problem is really a driver issue or some other thing.

  I have a problem with Ubuntu 11.10. I can connect my Nokia C6-01 as a Massive Storage and Ubuntu will recognize it like a flash drive. But when I try to use Songbird, Rhythmbox, GMusic Browser and Amarok they arent even detecting it. I checked the add ons in everyone of them and they all have the mtp one. I want to be able to synchronize without problems my phone´s music but it´s so annoying to drag and drop my music and podcasts.

• How to get Ubuntu automatically connect to (windows, cabled & shared) network folder?

  - by Koen

  Through the normal processes I enter my shared music folder on my Windows computer, i.e.: Places Network Windows pc Music. After rebooting my Ubuntu laptop, however, this connection isn't automatically set again. My question: How do I get Ubuntu to automatically connect to that shared folder after login (while first checking whether the Windows computer is 'online')? This because I added the folder to the Banshee Library, and I currently first have to go to the shared folder manually before Banshee can play the files.

• Why wont a simple socket to the localhost connect?

  - by Jake M

  I am following a tutorial that teaches me how to use win32 sockets(winsock2). I am attempting to create a simple socket that connects to the "localhost" but my program is failing when I attempt to connect to the local host(at the function connect()). Do I need admin privileges to connect to the localhost? Maybe thats why it fails? Maybe theres a problem with my code? I have tried the ports 8888 & 8000 & they both fail. Also if I change the port to 80 & connect to www.google.com I can connect BUT I get no response back. Is that because I haven't sent a HTTP request or am I meant to get some response back? Here's my code (with the includes removed): // Constants & Globals // typedef unsigned long IPNumber; // IP number typedef for IPv4 const int SOCK_VER = 2; const int SERVER_PORT = 8888; // 8888 SOCKET mSocket = INVALID_SOCKET; SOCKADDR_IN sockAddr = {0}; WSADATA wsaData; HOSTENT* hostent; int _tmain(int argc, _TCHAR* argv[]) { // Initialise winsock version 2.2 if (WSAStartup(MAKEWORD(SOCK_VER,2), &wsaData) != 0) { printf("Failed to initialise winsock\n"); WSACleanup(); system("PAUSE"); return 0; } if (LOBYTE(wsaData.wVersion) != SOCK_VER || HIBYTE(wsaData.wVersion) != 2) { printf("Failed to load the correct winsock version\n"); WSACleanup(); system("PAUSE"); return 0; } // Create socket mSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); if (mSocket == INVALID_SOCKET) { printf("Failed to create TCP socket\n"); WSACleanup(); system("PAUSE"); return 0; } // Get IP Address of website by the domain name, we do this by contacting(??) the Domain Name Server if ((hostent = gethostbyname("localhost")) == NULL) // "localhost" www.google.com { printf("Failed to resolve website name to an ip address\n"); WSACleanup(); system("PAUSE"); return 0; } sockAddr.sin_port = htons(SERVER_PORT); sockAddr.sin_family = AF_INET; sockAddr.sin_addr.S_un.S_addr = (*reinterpret_cast <IPNumber*> (hostent->h_addr_list[0])); // sockAddr.sin_addr.s_addr=*((unsigned long*)hostent->h_addr); // Can also do this // ERROR OCCURS ON NEXT LINE: Connect to server if (connect(mSocket, (SOCKADDR*)(&sockAddr), sizeof(sockAddr)) != 0) { printf("Failed to connect to server\n"); WSACleanup(); system("PAUSE"); return 0; } printf("Got to here\r\n"); // Display message from server char buffer[1000]; memset(buffer,0,999); int inDataLength=recv(mSocket,buffer,1000,0); printf("Response: %s\r\n", buffer); // Shutdown our socket shutdown(mSocket, SD_SEND); // Close our socket entirely closesocket(mSocket); // Cleanup Winsock WSACleanup(); system("pause"); return 0; }

• How to prevent Android bluetooth RFCOMM connection from dying immediately after .connect()?

  - by Gilead

  I'm trying to connect to a Zeemote (http://zeemote.com/) gaming controller from Moto Droid running 2.0.1 firmware.

• Small adventure game

  - by Nick Rosencrantz

  I'm making a small adventure game where the player can walk through Dungeons and meet scary characters: The whole thing is 20 java classes and I'm making this a standalone frame while it could very well be an applet I don't want to make another applet since I might want to recode this in C/C++ if the game or game engine turns out a success. The engine is the most interesting part of the game, it controls players and computer-controlled characters such as Zombies, Reptile Warriors, Trolls, Necromancers, and other Persons. These persons can sleep or walk around in the game and also pick up and move things. I didn't add many things so I suppose that is the next thing to do is to add things that can get used now that I already added many different types of walking persons. What do you think I should add and do with things in the game? The things I have so far is: package adventure; /** * The data type for things. Subclasses will be create that takes part of the story */ public class Thing { /** * The name of the Thing. */ public String name; /** * @param name The name of the Thing. */ Thing( String name ) { this.name = name; } } public class Scroll extends Thing { Scroll (String name) { super(name); } } class Key extends Thing { Key (String name) { super(name); } } The key is the way to win the game if you figure our that you should give it to a certain person and the scroll can protect you from necromancers and trolls. If I make this game more Dungeons and Dragons-inspired, do you think will be any good? Any other ideas that you think I could use here? The Threadwhich steps time forward and wakes up persons is called simulation. Do you think I could do something more advanced with this class? package adventure; class Simulation extends Thread { private PriorityQueue Eventqueue; Simulation() { Eventqueue = new PriorityQueue(); start(); } public void wakeMeAfter(Wakeable SleepingObject, double time) { Eventqueue.enqueue(SleepingObject, System.currentTimeMillis()+time); } public void run() { while(true) { try { sleep(5); //Sov i en halv sekund if (Eventqueue.getFirstTime() <= System.currentTimeMillis()) { ((Wakeable)Eventqueue.getFirst()).wakeup(); Eventqueue.dequeue(); } } catch (InterruptedException e ) { } } } } And here is the class that makes up the actual world: package adventure; import java.awt.*; import java.net.URL; /** * Subklass to World that builds up the Dungeon World. */ public class DungeonWorld extends World { /** * * @param a Reference to adventure game. * */ public DungeonWorld(Adventure a) { super ( a ); // Create all places createPlace( "Himlen" ); createPlace( "Stairs3" ); createPlace( "IPLab" ); createPlace( "Dungeon3" ); createPlace( "Stairs5" ); createPlace( "C2M2" ); createPlace( "SANS" ); createPlace( "Macsal" ); createPlace( "Stairs4" ); createPlace( "Dungeon2" ); createPlace( "Datorsalen" ); createPlace( "Dungeon");//, "Ljushallen.gif" ); createPlace( "Cola-automaten", "ColaAutomat.gif" ); createPlace( "Stairs2" ); createPlace( "Fable1" ); createPlace( "Dungeon1" ); createPlace( "Kulverten" ); // Create all connections between places connect( "Stairs3", "Stairs5", "Down", "Up" ); connect( "Dungeon3", "SANS", "Down", "Up" ); connect( "Dungeon3", "IPLab", "West", "East" ); connect( "IPLab", "Stairs3", "West", "East" ); connect( "Stairs5", "Stairs4", "Down", "Up" ); connect( "Macsal", "Stairs5", "South", "Norr" ); connect( "C2M2", "Stairs5", "West", "East" ); connect( "SANS", "C2M2", "West", "East" ); connect( "Stairs4", "Dungeon", "Down", "Up" ); connect( "Datorsalen", "Stairs4", "South", "Noth" ); connect( "Dungeon2", "Stairs4", "West", "East" ); connect( "Dungeon", "Stairs2", "Down", "Up" ); connect( "Dungeon", "Cola-automaten", "South", "North" ); connect( "Stairs2", "Kulverten", "Down", "Up" ); connect( "Stairs2", "Fable1", "East", "West" ); connect( "Fable1", "Dungeon1", "South", "North" ); // Add things // --- Add new things here --- getPlace("Cola-automaten").addThing(new CocaCola("Ljummen cola")); getPlace("Cola-automaten").addThing(new CocaCola("Avslagen Cola")); getPlace("Cola-automaten").addThing(new CocaCola("Iskall Cola")); getPlace("Cola-automaten").addThing(new CocaCola("Cola Light")); getPlace("Cola-automaten").addThing(new CocaCola("Cuba Cola")); getPlace("Stairs4").addThing(new Scroll("Scroll")); getPlace("Dungeon3").addThing(new Key("Key")); Simulation sim = new Simulation(); // Load images to be used as appearance-parameter for persons Image studAppearance = owner.loadPicture( "Person.gif" ); Image asseAppearance = owner.loadPicture( "Asse.gif" ); Image trollAppearance = owner.loadPicture( "Loke.gif" ); Image necromancerAppearance = owner.loadPicture( "Necromancer.gif" ); Image skeletonAppearance = owner.loadPicture( "Reptilewarrior.gif" ); Image reptileAppearance = owner.loadPicture( "Skeleton.gif" ); Image zombieAppearance = owner.loadPicture( "Zombie.gif" ); // --- Add new persons here --- new WalkingPerson(sim, this, "Peter", studAppearance); new WalkingPerson(sim, this, "Zombie", zombieAppearance ); new WalkingPerson(sim, this, "Zombie", zombieAppearance ); new WalkingPerson(sim, this, "Skeleton", skeletonAppearance ); new WalkingPerson(sim, this, "John", studAppearance ); new WalkingPerson(sim, this, "Skeleton", skeletonAppearance ); new WalkingPerson(sim, this, "Skeleton", skeletonAppearance ); new WalkingPerson(sim, this, "Skeleton", skeletonAppearance ); new WalkingPerson(sim, this, "Sean", studAppearance ); new WalkingPerson(sim, this, "Reptile", reptileAppearance ); new LabAssistant(sim, this, "Kate", asseAppearance); new LabAssistant(sim, this, "Jenna", asseAppearance); new Troll(sim, this, "Troll", trollAppearance); new Necromancer(sim, this, "Necromancer", necromancerAppearance); } /** * * The place where persons are placed by default * *@return The default place. * */ public Place defaultPlace() { return getPlace( "Datorsalen" ); } private void connect( String p1, String p2, String door1, String door2) { Place place1 = getPlace( p1 ); Place place2 = getPlace( p2 ); place1.addExit( door1, place2 ); place2.addExit( door2, place1 ); } } Thanks

• How can I connect any USB device to my computer wirelessly?

  - by daviesgeek

  I am trying to connect the Canon 550D wirelessly to my computer so that I can control it from at a distance. It can connect normally via a USB cable, so I was wondering if there was a way to plug a dongle into the computer, and a dongle into the camera so the two can connect. I'm basically looking for a really long USB cord that will work over long distances (200+ feet). Another important factor is that I really would prefer not having use a power cord, rather just plugging in a dongle, as it will make the setup more mobile. Does anything like this exist? (I know that Cables Unlimited had something like what I wanted, but they went out of business last year)

• Mysterious problem...can remotely connect to a system but can't browse back out.

  - by GregH

  I have LogMeIn installed on my home system. I went on travel and my wife called saying that none of our home systems could browse the internet. I thought I would try to connect to my home system using logmein. Surprisingly, I was able to connect to my home system and log in without any problems using logmein. When I opened a browser from my home system, I indeed could not browse. I opened a command prompt and tried to ping my router (192.168.1.1) and it failed/timed out. How is this possible? I can remotely connect to my system but once logged in cannot even ping my router. What's up with that?

  I've installed a stock mysql 5.5 installation, and while I can connect to the mysql service via the mysql command, and the service seems to be running, I cannot connect to it through spring+tomcat or from an external jdbc connector. I'm using the following URL: jdbc:mysql://myserver.com:myport/mydb with proper username/password, but I receive the following message: server.com: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. the driver has not received any packets from the server. and tomcat throws: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) Which seems to be the same issue as if I try to connect externally.

• How can I stop my laptop display from flickering when I connect my TV?

  - by Lord Torgamus

  I have a laptop with an HDMI output port running Vista, and an HDTV with HDMI input ports. The laptop is set to extend its desktop onto a second monitor. When I connect the computer to the TV with an HDMI cable, my laptop screen usually flickers rapidly. Most of the time it lasts for about 30 seconds, but sometimes it lasts for several minutes and once in a while it doesn't happen at all. It wouldn't be so bad except that the cursor moves back to the center of the laptop screen with each flicker, so I can't really do anything until the machine decides it's ready to calm down. I haven't been able to find any pattern at all for the causes or duration of the flickering. It doesn't seem to matter what programs the laptop is running when I connect it to the TV, whether I enable the extended display before or after I connect the TV or which HDMI port/cable I use. What could be causing this, and how can I make it go away?

• How do ring and bus network connect to router?

  - by lantopology

  Sorry this is probably a very silly question, but for some reason i am confused. How does a LAN with bus or ring topology connect to a router and other LANs? For example in a star network they all connect to a switch which can then connect to a router, but where does a switch go and fit in a bus or ring topology? In this image of a ring network there is no switch: http://www.brainbell.com/tutorials/Networking/images/01fig04.gif would the switch in the ring network simply be placed alongside the other nodes? Thank you very much

  Just for the fun of it, I want to get an old Tandy 1400LT laptop: small monochrome display two floppy drives rs-232c connector "printer" connector connect the thing the internet and use it as an ssh terminal. How would I connect it to the internet? The software should be no problem as it is a 386 hardware. There should be a small linux distribution which can be run on it. But how would I phisically connect the hardware? It has no ethernet port. Has someone experience with Serial/Paralel-to-ethernet converters?
