  • How to connect to a wireless network that has a two word name with a space?

    - by grinan
    Ok, I have searched for some time in earnest for an answer to this question. I have a Beagleboard which has Ubuntu 10.10 Minimal install for Arm running on it. With the default install, minimal tools, no GUI, I am unable to connect to my wireless network. The name of my network is "MYNAME NETWORK". Using a text editor to edit /etc/network/interfaces I can not seem to connect at all. As an experiment, I connected to a friends network, which has a one word name "dystek",and was able to connect with Zero issues, and update and install a full GUI for ubuntu Arm. The problem is that I don't want a full blown gui on the beagleboard, just a minimal install of ubuntu with CLI is all I need or want. Is there anyway to connect to my wireless network via editing the /etc/network/interfaces file. Surely there is... I just don't know how. Right now my interfaces file looks like this: auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.1.200 netmask 255.255.255.0 gateway 192.168.1.1 wireless-essid BARRETT NETWORK wireless-key 46456xxxxxxxx Any help would be appreciated.

  • Installing mysql on leopard: "Can't connect to local MySQL server through socket"

    - by Neil
    I migrated to a new machine and used migration assistant to copy across my files (which seemed to copy across the DBs) but I had to use macports to install Mysql (whereas last time I compiled from source via Dan Benjamin's guide). For some reason, mysql is intermittently throwing the following error; Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2) It does this no matter what I try, which has included setting the socket in /opt/local/etc/mysql5/my.cnf. Previously I've managed to temporarily fix this by restarting the machine, but right now it just doesn't want to know, despite grep mysql telling me I seem to have a pid; 0 46 1 0 0:00.01 ?? 0:00.01 /opt/local/bin/daemondo --label=mysql5 --start-cmd /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper start ; --stop-cmd /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper stop ; --restart-cmd /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper restart ; --pid=none 0 70 1 0 0:00.01 ?? 0:00.01 /bin/sh /opt/local/lib/mysql5/bin/mysqld_safe --datadir=/opt/local/var/db/mysql5 --pid-file=/opt/local/var/db/mysql5/localhost.pid 74 100 70 0 0:09.22 ?? 1:02.68 /opt/local/libexec/mysqld --basedir=/opt/local --datadir=/opt/local/var/db/mysql5 --user=mysql --pid-file=/opt/local/var/db/mysql5/localhost.pid --socket=/tmp/mysql.sock 501 66217 65266 0 0:00.00 ttys001 0:00.00 grep mysql How do I fix this? Are there any steps I can take next? I've been trying for a few weeks now and I've read round all relevant blog posts, so I'm completely out of ideas.

  • facebook connect api "Cannot use string offset as an array in" error

    - by Rees
    Please help! I have been grappling with this error for days and I cannot for the life of me figure it out. I am using facebook connect and fetching a "contact_email" attribute using their api method users_getInfo. The issue is that when I execute this PHP file, i get this error: "Cannot use string offset as an array in...". This error specifically refers to this line of code: $firstName=$user_details[0]['contact_email']; I'm thinking this is because the user_getInfo method is not returning any results... However, the most ridiculous part about all this is that, I can execute the code below several dozens of times in a row SUCCESSFULLY without the above error, BUT THEN randomly without changing ANY code at all, I will suddenly encounter this error, in which case it will begin to give me an error several dozens of times, and then AGAIN without any code change, start executing successfully again. This odd behavior occurs regardless of the attribute i am fetching.. (contact_email, first_name, last_name, etc.). I am running php 5.2.11. Is there something I'm missing?? Please Help! include_once 'site/fbconnect/config.php'; //has $api_key and $secret defined. include_once 'site/facebook-platform/client/facebook.php'; global $api_key,$secret; $fb=new Facebook($api_key,$secret); $fb-require_login(); $fb_user=$fb-get_loggedin_user(); $user_details=$fb-api_client-users_getInfo($fb_user,array('last_name','first_name','contact_email')); $email=$user_details[0]['contact_email']; $firstName=$user_details[0]['first_name']; $lastName=$user_details[0]['last_name'];

  • Detecting which MCUs to connect on an incoming conference

    - by Fábio Batista
    Hello, SO. I'm working with the OCS UCCAPI, developing a custom OCS client. I'm currently having a hard time detecting what "kind" of Conference my client is being invited to. Using the Office Communicator client, I can start "IM conferences" (by inviting more than 1 person and selecting "start a IM conversation") or "video conferences" (by selecting more than 1 person and selecting "start a video call"). The Office Communicator client, on the invitees' end, starts correctly the appropriate session (just IM, just Video or IM+Video). However, when receiving the conference invite on my custom client, there's no data about the kind of session I'm being invited. I need this information, in order to make a decision whether or not to connect to the AV MCU and capture/show video. I've tried already: When handling _IUccSessionManagerEvents.OnIncomingSession, parse the RemoteSessionDescription property on the UccIncomingInvitationEvent object: no luck, the only data about the conference modality is an element on the XML about the IM being enabled or not (<im available="true"> or <im available="false">), but nothing about the session having video available or not. When handling _IUccConferenceSessionEvents.OnEnter, check the Media property on the UccConferenceSession. Don't work, all media types are present (MESSAGE, AUDIO, VIDEO, DATA e TELEPHONY), regardless of the type of conference I'm being invited. Also when handling _IUccConferenceSessionEvents.OnEnter, check the Entities collection on the UccConferenceView object, to check which MCUs are enabled for this conference. Don't work either, all MUCs are listed as available (IM, AV, DATA and CONTROL), regardless of the type of conference I'm being invited. I'm running out of ideas. Some references I'm using: http://msdn.microsoft.com/en-us/library/bb664307.aspx http://msdn.microsoft.com/en-us/library/dd170830.aspx Thanks a lot.

  • Unable to connect to UNC share with WindowsIdentity.Impersonate, but works fine using LogonUser

    - by Rob
    Hopefully I'm not missing something obvious here, but I have a class that needs to create some directories on a UNC share and then move files to the new directory. When we connect using LogonUser things work fine with no errors, but when we try and use the user indicated by Integrated Windows authentication we run into problems. Here's some working and non-working code to give you an idea what is going on. The following works and logs the requested information: [DllImport("advapi32.dll", SetLastError = true)] private static extern bool LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, out IntPtr phToken); [DllImport("kernel32.dll", CharSet = CharSet.Auto)] private static extern bool CloseHandle(IntPtr handle); IntPtr token; WindowsIdentity wi; if (LogonUser("user", "network", "password", 8, // LOGON32_LOGON_NETWORK_CLEARTEXT 0, // LOGON32_PROVIDER_DEFAULT out token)) { wi = new WindowsIdentity(token); WindowsImpersonationContext wic = wi.Impersonate(); Logging.LogMessage(System.Security.Principal.WindowsIdentity.GetCurrent().Name); Logging.LogMessage(path); DirectoryInfo info = new DirectoryInfo(path); Logging.LogMessage(info.Exists.ToString()); Logging.LogMessage(info.Name); Logging.LogMessage("LastAccessTime:" + info.LastAccessTime.ToString()); Logging.LogMessage("LastWriteTime:" + info.LastWriteTime.ToString()); wic.Undo(); CloseHandle(token); } The following fails and gives an error message indicating the network name is not available, but the correct user name is indicated by GetCurrent().Name: WindowsIdentity identity = (WindowsIdentity)HttpContext.Current.User.Identity; using (identity.Impersonate()) { Logging.LogMessage(System.Security.Principal.WindowsIdentity.GetCurrent().Name); Logging.LogMessage(path); DirectoryInfo info = new DirectoryInfo(path); Logging.LogMessage(info.Exists.ToString()); Logging.LogMessage(info.Name); Logging.LogMessage("LastAccessTime:" + info.LastAccessTime.ToString()); Logging.LogMessage("LastWriteTime:" + info.LastWriteTime.ToString()); }

  • Unable to connect on socket across different networks.

    - by maleki
    I am having trouble connecting my online application to others across another network. I am able to give them the hostAddress to connect when we are on the same network but when we are doing it across the internet the generated host address doesn't allow a connection, nor does using the ip address gotten from online sites such as whatismyip.com My biggest issue isn't debugging this code, because it works over intra-network but The server doesn't see attempts when we try to move to different networks. Also, the test ip I am using is 2222. InetAddress addr = InetAddress.getLocalHost(); String hostname = addr.getHostName(); System.out.println("Hostname: " + hostname); System.out.println("IP: " + addr.getHostAddress()); I display the host to the server when it is starting if (isClient) { System.out.println("Client Starting.."); clientSocket = new Socket(host, port_number); } else { System.out.println("Server Starting.."); echoServer = new ServerSocket(port_number); clientSocket = echoServer.accept(); System.out.println("Warning, Incoming Game.."); }

  • JConsole does not connect when a program (running in eclipse) is waiting for a console input

    - by Calm Storm
    Hi, I have a problem similar to the one mentioned here. I have a program which launches a selenium browser and refreshes it every 2 seconds. My idea here was to monitor the memory usage of my application as the page is being hit. This console program does a "System.in.read" and when a user presses enter key, this stops the browser refresh thread. I run the program and it runs as I would expect it to. But when I fire jconsole and attach it to the process, it looks like jconsole waits forever to attach. This is because of the "System.in.read", apparently as shown in the JConsole source. In my code it makes perfect sense for me to terminte the browser when user presses something so is there any alternative available at all ? (Posted code sample below) package com.ekanathk; import java.util.ArrayList; import java.util.List; import org.junit.Test; public class MultiThread { @Test public void testSimple() throws Exception { List<Integer> x = new ArrayList<Integer>(); for(int i = 0; i < 1000; i++) { x.add(i); } System.out.print("Press Enter to stop (try attach a jconsole now...."); System.in.read(); } } The problem here seems to be that any System.in.read (either in Main thread or any threads) seems to completely block jconsole. I guess the problem essentially boils down to multiple threads requesting system inputs at the same time? Is there a solution ? UPDATE 1: It seems this works fine when launching the class from a command line, however when I run from eclipse, jconsole cant connect. Any reasons ?

  • C# connect to domain SQL Server 2005 from non-domain machine

    - by user304582
    Hi, I asked a question a few days ago (http://stackoverflow.com/questions/2795723/access-to-sql-server-2005-from-a-non-domain-machine-using-windows-authentication) which got some interesting, but not usable suggestions. I'd like to ask the question again, but make clear what my constraints are: I have a Windows domain within which a machine is running SQL Server 2005 and which is configured to support only Windows authentication. I would like to run a C# client application on a machine on the same network, but which is NOT on the domain, and access a database on the SQL Server 2005 instance. I CANNOT create or modify OS or SQL Server users on either machine, and I CANNOT make any changes to permissions or impersonation, and I CANNOT make use of runas. I know that I can write Perl and Java applications that can connect to the SQL Server database using only these four parameters: server name, database name, username (in the form domain\user), and password. In C# I have tried various things around: string connectionString = "Data Source=server;Initial Catalog=database;User Id=domain\user;Password=password"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); and tried setting integrated security to true and false, but nothing seems to work. Is what I am trying to do simply impossible in C#? Thanks for any help, Martin

I'm using JRuby 1.2.0 and I have ojdbc14.jar in my JRuby lib directory Gems: ActiveRecord-JDBC (0.5) activerecord-jdbc-adapter (0.9.1) activerecord (2.2.2) What am I missing? Thanks,

  • ORA- 01157 / Cant connect to database

    - by Tom
    Hi everyone, this is a follow up from this question. Let me start by saying that i am NOT a DBA, so i'm really really lost with this. A few weeks ago, we lost contact with one of our SID'S. All the other services are working, but this one in particular is not. What we got was this message when trying to connect ORA-01033: ORACLE initialization or shutdown in progress An attempt to alter database open ended up in ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' I tried to shutdown / restart the database, but got this message. Total System Global Area 566231040 bytes Fixed Size 1220604 bytes Variable Size 117440516 bytes Database Buffers 444596224 bytes Redo Buffers 2973696 bytes Database mounted. ORA-01157: cannot identify/lock data file 6 - see DBWR trace file ORA-01110: data file 6: '/u01/app/oracle/oradata/xxx/xxx_data.dbf' When all continued the same, I erased the dbf files (rm xxx_data.dbf xxx_index.dbf), and recreated them using touch xxx_data.dbf. I also tried to recreate the tablespaces using `CREATE TABLESPACE DATA DATAFILE XXX_DATA.DBF` and got Database not open As I said, i don't know how bad this is, or how far i'm from gaining access to my database (well, to this SID at least, the others are working). I would imagine that a last resource would be to throw everything away, and recreating it, but I don't know how to, and I was hoping there's a less destructive solution. Any help will be greatly appreciated . Thanks in advance.

  • Connect to a remote Oracle 11g server using OracleClient of .NET 2.0

    - by Raghu M
    I have to connect to a Oracle server on the network using a .NET / C# (Winform) application. I am trying to use System.Data.OracleClient but in vain. Here are the details I can possibly think of (that might help someone reading this question): Platform: Visual Studio 2005 / .NET 2.0 with C# on Windows Vista Home Premium Library: System.Data.OracleClient Server: Oracle 11g (located on the same LAN) Please note that I don't have Oracle installed locally and I have hunted every discussion forum possible for help - but most of them assume local Oracle installation! Here is my connection string: "User Id=TSUSER;Password=ts12TS;Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyServerIP)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL)));" And I get this error: OCIEnvCreate failed with return code -1 but error message text was not available.

  • Cannot connect Nexus One Phone to Android adb

    - by appbee
    I am running Android SDK 2.2 and am trying to get the adb to connect to the Google Nexus One phone. Its a new phone, shipped straight from Google - haven't installed any apps on it yet. (I have Windows XP) Here is what I have done so far: Followed the instructions on setting up the device for development as given on the Android Developer's site: http://developer.android.com/guide/developing/device.html added android:debuggable="true" to my application manifest USB debuggable is checked on the phone downloaded the Device Drivers For Windows Revision 3 (this supports Nexus One phones) Went through the Hardware Installation wizard to install the device - the device shows up as "Android Composite ADB Interface". When I run adb devices on the shell, the device appears for a moment, then disappears. On the Eclipse console, I get the following message: [2010-11-13 11:54:42 - DeviceMonitor]Failed to start monitoring I have rebooted the pc several times, uninstalled and reinstalled the drivers several times, but I get the same error each time. As I was researching this problem, someone had recommended rebooting the phone. I am a bit confused by that - is that a soft or hard reboot? Do I just power the phone off/on and is there something more complex involved? Do I have to hard reboot it to reset to factory version - even though its brand new? Has anyone run into a similar problem? Any help on this would be great. I can't test my application on the device if the adb cannot view the device. Thanks so much in advance.

  • Cannot connect to SQL Server from ASP.NET MVC app

    - by Dan Fergus
    I have an ASP.NET MVC app that has on a hosted server for over a year, connecting to SQL Server. I've had to change hosting services, the new one supports MVC 1.0. I've also moved a non MVC ASP app to the same hosting service. Now, MY MVC based app retturnes this error when I try to validate a user login. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Now, the non-MVC app can access the exact same database and authenticate users just fine. The MVC app, when run from my dev box connects fine. It also run/connects/authenticates without problem when I install and run the site from an internal SQL 2008 server running IIS 7. I, along with the hosting support techs, am at a loss how the exact same connect string works every where except on the hosted server, and only when run from inside an ASP.NET MVC web app. Any ideas would be greatly appreciated.

  • Reporting Services "cannot connect to the report server database"

    - by Dano
    We have Reporting Services running, and twice in the past 6 months it has been down for 1-3 days, and suddenly it will start working again. The errors range from not being able to view the tree root in a browser, down to being able to insert parameters on a report, but crashing before the report can generate. Looking at the logs, there is 1 error and 1 warning which seem to correspond somewhat. ERROR:Event Type: Error Event Source: Report Server (SQL2K5) Event Category: Management Event ID: 107 Date: 2/13/2009 Time: 11:17:19 AM User: N/A Computer: ******** Description: Report Server (SQL2K5) cannot connect to the report server database.

Anyone out there have any ideas on what could be causing these issues? Edit Tried both suggestions below several months ago to no avail. This issue hasn't arisen since, maybe something out of my control has changed....

    - by Matt Wilde
    I've worked out most of the code and have several game classes. The one bit I'm stuck on at the moment, it how to draw the actual Connect 4 grid. Can anyone tell me what's wrong with this for loop? I get no errors but the grid doesn't appear. I'm using C#. private void Drawgrid() { Brush b = Brushes.Black; Pen p = Pens.Black; for (int xCoor = XStart, col = 0; xCoor < XStart + ColMax * DiscSpace; xCoor += DiscSpace, col++) // x coordinate beginning; while the x coordinate is smaller than the max column size, times it by // the space between each disc and then add the x coord to the disc space in order to create a new circle. for (int yCoor = YStart, row = RowMax - 1; yCoor < YStart + RowMax * DiscScale; yCoor += DiscScale, row--) { switch (Grid.State[row, col]) { case GameGrid.Gridvalues.Red: b = Brushes.Red; break; case GameGrid.Gridvalues.Yellow: b = Brushes.Yellow; break; case GameGrid.Gridvalues.None: b = Brushes.Aqua; break; } MainDisplay.DrawEllipse(p, xCoor, yCoor, 50, 50); MainDisplay.FillEllipse(b, xCoor, yCoor, 50, 50); } Invalidate(); } Thanks.

  • Cannot connect to mysql via servlet

    - by JBoy
    Hi all I have been since 2 days trying to figure out why my servlet does not connect to the database MySql. I have mysql installed and working properly and eclipse. Whenever i try to etabilish a connection i get the ClassNotFoundException for the com.mysql.jdbc.Driver, which is actually properly imported, the connector i'm using is the mysql-connector-java5.1.14 added properly as external jar so everything seems fine. here's my code protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String dbUrl="jdbc:mysql://localhost:3306/test"; String username="root"; String password=""; try { Class.forName("com.mysql.jdbc.Driver").newInstance(); conn=DriverManager.getConnection(dbUrl); System.out.println("Connected!"); } catch (SQLException e) { e.printStackTrace(); System.out.println("not connected"); } catch(ClassNotFoundException x){ x.printStackTrace(); } catch(Exception e){ e.printStackTrace(); } } The stacktrace(part of): java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1645) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1491) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:375) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:164) i'm following the connection steps from a published java book and also in forums and tutorials i just see the same code, cannot figure out why that Exception comes. On a normal application which does not run on the server the Exception isn't thrown and the connection (in the exact same way) its successfull. Do you have any advice?

  • To connect Gstreamer with Qt in order to play a gstreamer video in the Qt Widget

    - by raggio
    I tried using phonon to play the video but could not succeed. Off-late came to know through the Qt forums that even the latest version of Qt does not support phonon. Thats when i started using Gstreamer.Any suggestions as to how to connect the Gstreamer window with the Qt widget?My aim is to play a video using Gstreamer on the Qt widget.So how do i link the gstreamer window and the Qt widget? I am successful in getting the Id of the widget through winid(). Further with the help of Gregory Pakosz, I have added the below 2 lines of code in my application - QApplication::syncX(); gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(sink), widget->winId()); However am not able to link the Qt widget with the gstreamer video window. This is what my sample code would look like :- int main(int argc, char *argv[]) { printf("winid=%d\n", w.winId()); gst_init (NULL,NULL); /* create a new bin to hold the elements */ bin = gst_pipeline_new ("pipeline"); /* create a disk reader */ filesrc = gst_element_factory_make ("filesrc", "disk_source"); g_assert (filesrc); g_object_set (G_OBJECT (filesrc), "location", "PATH_TO_THE_EXECUTABLE", NULL); demux = gst_element_factory_make ("mpegtsdemux", "demuxer"); if (!demux) { g_print ("could not find plugin \"mpegtsmux\""); return -1; } vdecoder = gst_element_factory_make ("mpeg2dec", "decode"); if (!vdecoder) { g_print ("could not find plugin \"mpeg2dec\""); return -1; } videosink = gst_element_factory_make ("xvimagesink", "play_video"); g_assert (videosink); /* add objects to the main pipeline */ gst_bin_add_many (GST_BIN (bin), filesrc, demux, vdecoder, videosink, NULL); /* link the elements */ gst_element_link_many (filesrc, demux, vdecoder, videosink, NULL); gst_element_set_state(videosink, GST_STATE_READY); QApplication::syncX(); gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(videosink), w.winId()); /* start playing */ gst_element_set_state (bin, GST_STATE_PLAYING); } Could you explain more in detail about the usage of gst_x_overlay_set_xwindow_id() wrt my context? Could i get any hint as to how i can integrate gstreamer under Qt? Please help me solve this problem
