• Why does Akonadi on KDE 4.6.0 refuse to start?

  - by Patches

  Akonadi refuses to start on my fresh installation of KDE 4.6.0 from the kubuntu-backports PPA on Ubuntu 10.10 Maverick Meerkat, preventing me from usking KMail.

• Is there apt-cacher for Windows?

  - by Ted Kim

  I have two computers. C1: Windows with Internet connection. C2: Ubuntu connected with C1 but not connected with Internet. I'd like to access apt repositories to update or install some packages on Ubuntu. I heard, apt-cacher is one of solutions, but I couldn't find apt-cacher for Windows (It is only one, I have, with Internet connection). Please let me know how to do. Thanks in advance Ted Kim

• Library like ENet, but for TCP?

  - by Milo

  I'm not looking to use boost::asio, it is overly complex for my needs. I'm building a game that is cross platform, for desktop, iPhone and Android. I found a library called ENet which is pretty much what I need, but it uses UDP which does not seem to support encryption and a few other things. Given that the game is an event driven card game, TCP seems like the right fit. However, all I have found is WINSOCK / berkley sockets and bost::asio. Here is a sample client server application with ENet: #include <enet/enet.h> #include <stdlib.h> #include <string> #include <iostream> class Host { ENetAddress address; ENetHost * server; ENetHost* client; ENetEvent event; public: Host() :server(NULL) { enet_initialize(); setupServer(); } void setupServer() { if(server) { enet_host_destroy(server); server = NULL; } address.host = ENET_HOST_ANY; /* Bind the server to port 1234. */ address.port = 1721; server = enet_host_create (& address /* the address to bind the server host to */, 32 /* allow up to 32 clients and/or outgoing connections */, 2 /* allow up to 2 channels to be used, 0 and 1 */, 0 /* assume any amount of incoming bandwidth */, 0 /* assume any amount of outgoing bandwidth */); } void daLoop() { while(true) { /* Wait up to 1000 milliseconds for an event. */ while (enet_host_service (server, & event, 5000) > 0) { ENetPacket * packet; switch (event.type) { case ENET_EVENT_TYPE_CONNECT: printf ("A new client connected from %x:%u.\n", event.peer -> address.host, event.peer -> address.port); /* Store any relevant client information here. */ event.peer -> data = "Client information"; /* Create a reliable packet of size 7 containing "packet\0" */ packet = enet_packet_create ("packet", strlen ("packet") + 1, ENET_PACKET_FLAG_RELIABLE); /* Extend the packet so and append the string "foo", so it now */ /* contains "packetfoo\0" */ enet_packet_resize (packet, strlen ("packetfoo") + 1); strcpy ((char*)& packet -> data [strlen ("packet")], "foo"); /* Send the packet to the peer over channel id 0. */ /* One could also broadcast the packet by */ /* enet_host_broadcast (host, 0, packet); */ enet_peer_send (event.peer, 0, packet); /* One could just use enet_host_service() instead. */ enet_host_flush (server); break; case ENET_EVENT_TYPE_RECEIVE: printf ("A packet of length %u containing %s was received from %s on channel %u.\n", event.packet -> dataLength, event.packet -> data, event.peer -> data, event.channelID); /* Clean up the packet now that we're done using it. */ enet_packet_destroy (event.packet); break; case ENET_EVENT_TYPE_DISCONNECT: printf ("%s disconected.\n", event.peer -> data); /* Reset the peer's client information. */ event.peer -> data = NULL; } } } } ~Host() { if(server) { enet_host_destroy(server); server = NULL; } atexit (enet_deinitialize); } }; class Client { ENetAddress address; ENetEvent event; ENetPeer *peer; ENetHost* client; public: Client() :peer(NULL) { enet_initialize(); setupPeer(); } void setupPeer() { client = enet_host_create (NULL /* create a client host */, 1 /* only allow 1 outgoing connection */, 2 /* allow up 2 channels to be used, 0 and 1 */, 57600 / 8 /* 56K modem with 56 Kbps downstream bandwidth */, 14400 / 8 /* 56K modem with 14 Kbps upstream bandwidth */); if (client == NULL) { fprintf (stderr, "An error occurred while trying to create an ENet client host.\n"); exit (EXIT_FAILURE); } /* Connect to some.server.net:1234. */ enet_address_set_host (& address, "192.168.2.13"); address.port = 1721; /* Initiate the connection, allocating the two channels 0 and 1. */ peer = enet_host_connect (client, & address, 2, 0); if (peer == NULL) { fprintf (stderr, "No available peers for initiating an ENet connection.\n"); exit (EXIT_FAILURE); } /* Wait up to 5 seconds for the connection attempt to succeed. */ if (enet_host_service (client, & event, 20000) > 0 && event.type == ENET_EVENT_TYPE_CONNECT) { std::cout << "Connection to some.server.net:1234 succeeded." << std::endl; } else { /* Either the 5 seconds are up or a disconnect event was */ /* received.

I just need something that abstracts away the platform (eg, no WINSOCKS) and that has basic ability to keep track of connected clients and send them messages. Thanks

• How to Quickly Add Multiple IP Addresses to Windows Servers

  - by Sysadmin Geek

  If you have ever added multiple IP addresses to a single Windows server, going through the graphical interface is an incredible pain as each IP must be added manually, each in a new dialog box. Here’s a simple solution. Needless to say, this can be incredibly monotonous and time consuming if you are adding more than a few IP addresses. Thankfully, there is a much easier way which allows you to add an entire subnet (or more) in seconds. Adding an IP Address from the Command Line Windows includes the “netsh” command which allows you to configure just about any aspect of your network connections. If you view the accepted parameters using “netsh /?” you will be presented with a list of commands each which have their own list of commands (and so on). For the purpose of adding IP addresses, we are interested in this string of parameters: netsh interface ipv4 add address Note: For Windows Server 2003/XP and earlier, “ipv4″ should be replaced with just “ip” in the netsh command. If you view the help information, you can see the full list of accepted parameters but for the most part what you will be interested in is something like this: netsh interface ipv4 add address “Local Area Connection” 192.168.1.2 255.255.255.0 The above command adds the IP Address 192.168.1.2 (with Subnet Mask 255.255.255.0) to the connection titled “Local Area Network”. Adding Multiple IP Addresses at Once When we accompany a netsh command with the FOR /L loop, we can quickly add multiple IP addresses. The syntax for the FOR /L loop looks like this: FOR /L %variable IN (start,step,end) DO command So we could easily add every IP address from an entire subnet using this command: FOR /L %A IN (0,1,255) DO netsh interface ipv4 add address “Local Area Connection” 192.168.1.%A 255.255.255.0 This command takes about 20 seconds to run, where adding the same number of IP addresses manually would take significantly longer. A Quick Demonstration Here is the initial configuration on our network adapter: ipconfig /all Now run netsh from within a FOR /L loop to add IP’s 192.168.1.10-20 to this adapter: FOR /L %A IN (10,1,20) DO netsh interface ipv4 add address “Local Area Connection” 192.168.1.%A 255.255.255.0 After the above command is run, viewing the IP Configuration of the adapter now shows: Latest Features How-To Geek ETC How To Create Your Own Custom ASCII Art from Any Image How To Process Camera Raw Without Paying for Adobe Photoshop How Do You Block Annoying Text Message (SMS) Spam?

• How do you reset a USB device from the command line?

  - by Casey

  Is it possible to reset the connection of a USB device, without physically disconnecting/connecting from the PC? Specifically, my device is a digital camera. I'm using gphoto2, but lately I get "device read errors", so I'd like to try to do a software-reset of the connection. From what I can tell, there are no kernel modules being loaded for the camera.

• How to configure TATA Photon+ EC1261 HUAWEI

  - by user3215

  I'm running ubuntu 10.04. I have a newly purchased TATA Photon+ Internet connection which supports Windows and Mac. On the Internet I found a article saying that it could be configured on Linux. I followed the steps to install it on Ubuntu from this link. I am still not able to get online, and need some help. Also, it is very slow, but I was told that I would see speeds up to 3.1MB. I dont have wvdial installed and cannot install it from apt as I'm not connected to internet Booting from windows I dowloaded "wvdial" .deb package and tried to install on ubuntu but it's ended with dependency problem. Automatically, don't know how, I got connected to internet only for once. Immediately I installed wvdial package after this I followed the tutorials(I could not browse and upload the files here) . From then it's showing that the device is connected in the network connections but no internet connection. Once I disable the device, it won't show as connected again and I'll have to restart my system. Sometimes the device itself not detected(wondering if there is any command to re-read the all devices). output of wvdialconf /etc/wvdial.cof: #wvdialconf /etc/wvdial.conf Editing `/etc/wvdial.conf'.

• FM Radio without Internet?

  - by WitchCraft

  Question: Is it possible to use FM radio WITHOUT internet connection or special devices ? On my Android phone, I can plug in the headphones, which are in turn used as antenna. Since Android is Linux and Ubuntu is also Linux, it should be possible to do this on a plain old Ubuntu notebook (13.04), too. Is it ? If yes, which application can I use for FM-Radio ? Note: I repeat: Live FM-Radio WITHOUT internet connection at the time of listening :)

• Is throwing an error in unpredictable subclass-specific circumstances a violation of LSP?

  - by Motti Strom

  Say, I wanted to create a Java List<String> (see spec) implementation that uses a complex subsystem, such as a database or file system, for its store so that it becomes a simple persistent collection rather than an basic in-memory one. (We're limiting it specifically to a List of Strings for the purposes of discussion, but it could extended to automatically de-/serialise any object, with some help. We can also provide persistent Sets, Maps and so on in this way too.) So here's a skeleton implementation: class DbBackedList implements List<String> { private DbBackedList() {} /** Returns a list, possibly non-empty */ public static getList() { return new DbBackedList(); } public String get(int index) { return Db.getTable().getRow(i).asString(); // may throw DbExceptions! } // add(String), add(int, String), etc. ... } My problem lies with the fact that the underlying DB API may encounter connection errors that are not specified in the List interface that it should throw. My problem is whether this violates Liskov's Substitution Principle (LSP). Bob Martin actually gives an example of a PersistentSet in his paper on LSP that violates LSP. The difference is that his newly-specified Exception there is determined by the inserted value and so is strengthening the precondition. In my case the connection/read error is unpredictable and due to external factors and so is not technically a new precondition, merely an error of circumstance, perhaps like OutOfMemoryError which can occur even when unspecified. In normal circumstances, the new Error/Exception might never be thrown. (The caller could catch if it is aware of the possibility, just as a memory-restricted Java program might specifically catch OOME.) Is this therefore a valid argument for throwing an extra error and can I still claim to be a valid java.util.List (or pick your SDK/language/collection in general) and not in violation of LSP? If this does indeed violate LSP and thus not practically usable, I have provided two less-palatable alternative solutions as answers that you can comment on, see below. Footnote: Use Cases In the simplest case, the goal is to provide a familiar interface for cases when (say) a database is just being used as a persistent list, and allow regular List operations such as search, subList and iteration. Another, more adventurous, use-case is as a slot-in replacement for libraries that work with basic Lists, e.g if we have a third-party task queue that usually works with a plain List: new TaskWorkQueue(new ArrayList<String>()).start() which is susceptible to losing all it's queue in event of a crash, if we just replace this with: new TaskWorkQueue(new DbBackedList()).start() we get a instant persistence and the ability to share the tasks amongst more than one machine. In either case, we could either handle connection/read exceptions that are thrown, perhaps retrying the connection/read first, or allow them to throw and crash the program (e.g. if we can't change the TaskWorkQueue code).

• Please allow us to cancel loading of log in SQL Server Management Studio Log Viewer

  - by simonsabin

  The log viewer in management studio is really neat, however if you have large log files or are accessing a remote server over a slow connection it can take a long time to load the log records. Generally you only need the last x records, so you don’t need to load all the records. It would be great to have a cancel button to allow us to cancel the loading of the log records in SQL Server Management Studio. As an aside one of the best features in SQL 2005 was the ability to cancel your connection attempt...(read more)

• Solution for developers wanting to run a standalone WLS 10.3.6 server against JDev 11.1.1.6.0

  - by Chris Muir

  In my previous post I discussed how to install the 11.1.1.6.0 ADF Runtimes into a standalone WLS 10.3.6 server by using the ADF Runtime installer, not the JDeveloper installer.  Yet there's still a problem for developers here because JDeveloper 11.1.1.6.0 comes coupled with a WLS 10.3.5 server.  What if you want to develop, deploy and test with a 10.3.6 server?  Have we lost the ability to integrate the IDE and the WLS server where we can run and stop the server, deploy our apps automatically the server and more? JDeveloper actually solved this issue sometime back but not many people will have recognized the feature for what it does as it wasn't needed until now. Via the Application Server Navigator you can create 2 types of connections, one to a remote "standalone WLS" and another to an "integrated WLS".  It's this second option that is useful because what we can do is install a local standalone WLS 10.3.6 server on our developer PC, then create a separate "integrated WLS" connection to the standalone server.  Then by accessing your Application's properties through the Application menu -> Application Properties -> Run -> Bind to Integration Application Server option we can choose the newly created WLS server connection to work with our application. In this way JDeveloper will now treat the new server as if it was the integrated WLS.  It will start when we run and deploy our applications, terminate it at request and so on.  Of course don't forget you still need to install the ADF Runtimes for the server to be able to work with ADF applications. Note there is bug 13917844 lurking in the Application Server Navigator for at least JDev 11.1.1.6.0 and earlier.  If you right click the new connection and select "Start Server Instance" it will often start one of the other existing connections instead (typically the original IntegratedWebLogicServer connection).  If you want to manually start the server you can bypass this by using the Run menu -> Start Server Instance option which works correctly.

• Using the @ in SQL Azure Connections

  - by BuckWoody

  The other day I was working with a client on an application they were changing to a hybrid architecture – some data on-premise and other data in SQL Azure and Windows Azure Blob storage. I had them make a couple of corrections - the first was that all communications to SQL Azure need to be encrypted. It’s a simple addition to the connection string, depending on the library you use. Which brought up another interesting point. They had been using something that looked like this, using the .NET provider: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=LoginName;Password=myPassword; Trusted_Connection=False;Encrypt=True; This includes most of the formatting needed for SQL Azure. It specifies TCP as the transport mechanism, the database name is included, Trusted_Connection is off, and encryption is on. But it needed one more change: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=[LoginName]@[serverName];Password=myPassword; Trusted_Connection=False;Encrypt=True; Notice the difference? It’s the User ID parameter. It includes the @ symbol and the name of the server – not the whole DNS name, just the server name itself. The developers were a bit surprised, since it had been working with the first format that just used the user name. Why did both work, and why is one better than the other? It has to do with the connection library you use. For most libraries, the user name is enough. But for some libraries (subject to change so I don’t list them here) the server name parameter isn’t sent in the way the load balancer understands, so you need to include the server name right in the login, so the system can parse it correctly. Keep in mind, the string limit for that is 128 characters – so take the @ symbol and the server name into consideration for user names. The user connection info is detailed here: http://msdn.microsoft.com/en-us/library/ee336268.aspx Upshot? Include the @servername on your connection string just to be safe. And plan for that extra space…

• How to handle encryption key conflicts when synchronizing data?

  - by Rafael

  Assume that there is data that gets synchronized between several devices. The data is protected with a symmetric encryption algorithm and a key. The key is stored on each device and encrypted with a password. When a user changes the password only the key gets re-encrypted. Under normal circumstances, when there is a good network connection to other peers, the current key gets synchronized and all data on the new device gets encrypted with the same key. But how to handle situations where a new device doesn’t have a network connection and e.g. creates its own new, but incompatible key? How to keep the usability as high as possible under such circumstances? The application could detect that there is no network and hence refuse to start. That’s very bad usability in my opinion, because the application isn’t functional at all in this case. I don’t consider this a solution. The application could ignore the missing network connection and create a new key. But what to do when the application gains a network connection? There will be several incompatible keys and some parts of the underlying data could only be encrypted with one key and other parts with another key. The situation would get worse if there would be more keys than just two and the application would’ve to ask every time for a password when another object that should get decrypted with another key would be needed. It is very messy and time consuming to try to re-encrypt all data that is encrypted with another key with a main key. What should be the main key at all in this case? The oldest key? The key with the most encrypted objects? What if the key got synchronized but not all objects that got encrypted with this particular key? How should the user know for which particular password the application asks and why it takes probably very long to re-encrypt the data? It’s very hard to describe encryption “issues” to users. So far I didn’t find an acceptable solution, nor some kind of generic strategy. Do you have some hints about a concrete strategy or some books / papers that describe synchronization of symmetrically encrypted data with keys that could cause conflicts?

• Download files from a SharePoint site using the RSSBus SSIS Components

  - by dataintegration

  In this article we will show how to use a stored procedure included in the RSSBus SSIS Components for SharePoint to download files from SharePoint. While the article uses the RSSBus SSIS Components for SharePoint, the same process will work for any of our SSIS Components. Step 1: Open Visual Studio and create a new Integration Services Project. Step 2: Add a new Data Flow Task to the Control Flow screen and open the Data Flow Task. Step 3: Add an RSSBus SharePoint Source to the Data Flow Task. Step 4: In the RSSBus SharePoint Source, add a new Connection Manager, and add your credentials for the SharePoint site. Step 5: Now from the Table or View dropdown, choose the name of the Document Library that you are going to back up and close the wizard. Step 6: Add a Script Component to the Data Flow Task and drag an output arrow from the 'RSSBus SharePoint Source' to it. Step 7: Open the Script Component, go to edit the Input Columns, and choose all the columns. Step 8: This will open a new Visual Studio instance, with a project in it. In this project add a reference to the RSSBus.SSIS2008.SharePoint assembly available in the RSSBus SSIS Components for SharePoint installation directory. Step 9: In the 'ScriptMain' class, add the System.Data.RSSBus.SharePoint namespace and go to the 'Input0_ProcessInputRow' method (this method's name may vary depending on the input name in the Script Component). Step 10: In the 'Input0_ProcessInputRow' method, you can add code to use the DownloadDocument stored procedure. Below we show the sample code: String connString = "Offline=False;Password=PASSWORD;User=USER;URL=SHAREPOINT-SITE"; String downloadDir = "C:\\Documents\\"; SharePointConnection conn = new SharePointConnection(connString); SharePointCommand comm = new SharePointCommand("DownloadDocument", conn); comm.CommandType = CommandType.StoredProcedure; comm.Parameters.Clear(); String file = downloadDir+Row.LinkFilenameNoMenu.ToString(); comm.Parameters.Add(new SharePointParameter("@File", file)); String list = Row.ServerUrl.ToString().Split('/')[1].ToString(); comm.Parameters.Add(new SharePointParameter("@Library", list)); String remoteFile = Row.LinkFilenameNoMenu.ToString(); comm.Parameters.Add(new SharePointParameter("@RemoteFile", remoteFile)); comm.ExecuteNonQuery(); After saving your changes to the Script Component, you can execute the project and find the downloaded files in the download directory. SSIS Sample Project To help you with getting started using the SharePoint Data Provider within SQL Server SSIS, download the fully functional sample package. You will also need the SharePoint SSIS Connector to make the connection. You can download a free trial here. Note: Before running the demo, you will need to change your connection details in both the 'Script Component' code and the 'Connection Manager'.
