• Get CruiseControl to talk to github with the correct public key.

  - by Jezmond

  Hi All, Has anybody installed git and ControlControl and got CruiseControl to pull from GitHub on a window 2003 server. I keep getting public key errors (access denied) - Which is good i suppose as that confirms git is talking to github. However what is not good is that I dont not know where to install the rsa keys so they will be picked up by the running process (git in the context of cc.net). Any help would save me a lot of hair! I have tried installing the keys into; c:\Program Files\Git.ssh Whereby running git bash and cd ~ take me to: c:\Program Files\Git Thanks in advance

• Invalid or expired security context token in WCF web service

  - by Damian

  All, I have a WCF web service (let's called service "B") hosted under IIS using a service account (VM, Windows 2003 SP2). The service exposes an endpoint that use WSHttpBinding with the default values except for maxReceivedMessageSize, maxBufferPoolSize, maxBufferSize and some of the time outs that have been increased. The web service has been load tested using Visual Studio Load Test framework with around 800 concurrent users and successfully passed all tests with no exceptions being thrown. The proxy in the unit test has been created from configuration. There is a sharepoint application that use the Office Sharepoint Server Search service to call web services "A" and "B". The application will get data from service "A" to create a request that will be sent to service "B". The response coming from service "B" is indexed for search. The proxy is created programmatically using the ChannelFactory. When service "A" takes less than 10 minutes, the calls to service "B" are successfull. But when service "A" takes more time (~20 minutes) the calls to service "B" throw the following exception: Exception Message: An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail Inner Exception Message: The message could not be processed. This is most likely because the action 'namespace/OperationName' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding. The binding settings are the same, the time in both client server and web service server are synchronize with the Windows Time service, same time zone. When i look at the server where web service "B" is hosted i can see the following security errors being logged: Source: Security Category: Logon/Logoff Event ID: 537 User NT AUTHORITY\SYSTEM Logon Failure: Reason: An error occurred during logon Logon Type: 3 Logon Process: Kerberos Authentication Package: Kerberos Status code: 0xC000006D Substatus code: 0xC0000133 After reading some of the blogs online, the Status code means STATUS_LOGON_FAILURE and the substatus code means STATUS_TIME_DIFFERENCE_AT_DC. but i already checked both server and client clocks and they are syncronized. I also noticed that the security token seems to be cached somewhere in the client server because they have another process that calls the web service "B" using the same service account and successfully gets data the first time is called. Then they start the proccess to update the office sharepoint server search service indexes and it fails. Then if they called the first proccess again it will fail too. Has anyone experienced this type of problems or have any ideas? Regards, --Damian

• Timeout Expired error Using LINQ

  - by Refracted Paladin

  I am going to sum up my problem first and then offer massive details and what I have already tried. Summary: I have an internal winform app that uses Linq 2 Sql to connect to a local SQL Express database. Each user has there own DB and the DB stay in sync through Merge Replication with a Central DB. All DB's are SQL 2005(sp2or3). We have been using this app for over 5 months now but recently our users are getting a Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Detailed: The strange part is they get that in two differnt locations(2 differnt LINQ Methods) and only the first time they fire in a given time period(~5mins). One LINQ method is pulling all records that match a FK ID and then Manipulating them to form a Heirarchy View for a TreeView. The second is pulling all records that match a FK ID and dumping them into a DataGridView. The only things I can find in common with the 2 are that the first IS an IEnumerable and the second converts itself from IQueryable - IEnumerable - DataTable... I looked at the query's in Profiler and they 'seemed' normal. They are not very complicated querys. They are only pulling back 10 - 90 records, from one table. Any thoughts, suggestions, hints whatever would be greatly appreciated. I am at my wit's end on this.... public IList<CaseNoteTreeItem> GetTreeViewDataAsList(int personID) { var myContext = MatrixDataContext.Create(); var caseNotesTree = from cn in myContext.tblCaseNotes where cn.PersonID == personID orderby cn.ContactDate descending, cn.InsertDate descending select new CaseNoteTreeItem { CaseNoteID = cn.CaseNoteID, NoteContactDate = Convert.ToDateTime(cn.ContactDate). ToShortDateString(), ParentNoteID = cn.ParentNote, InsertUser = cn.InsertUser, ContactDetailsPreview = cn.ContactDetails.Substring(0, 75) }; return caseNotesTree.ToList<CaseNoteTreeItem>(); } AND THIS ONE public static DataTable GetAllCNotes(int personID) { using (var context = MatrixDataContext.Create()) { var caseNotes = from cn in context.tblCaseNotes where cn.PersonID == personID orderby cn.ContactDate select new { cn.ContactDate, cn.ContactDetails, cn.TimeSpentUnits, cn.IsCaseLog, cn.IsPreEnrollment, cn.PresentAtContact, cn.InsertDate, cn.InsertUser, cn.CaseNoteID, cn.ParentNote }; return caseNotes.ToList().CopyLinqToDataTable(); } }

• Page expired issue with back button and wicket SortableDataProvider and DataTable

  - by David

  Hi, I've got an issue with SortableDataProvider and DataTable in wicket. I've defined my DataTable as such: IColumn<Column>[] columns = new IColumn[9]; //column values are mapped to the private attributes listed in ColumnImpl.java columns[0] = new PropertyColumn(new Model("#"), "columnPosition", "columnPosition"); columns[1] = new PropertyColumn(new Model("Description"), "description"); columns[2] = new PropertyColumn(new Model("Type"), "dataType", "dataType"); Adding it to the table: DataTable<Column> dataTable = new DataTable<Column>("columnsTable", columns, provider, maxRowsPerPage) { @Override protected Item<Column> newRowItem(String id, int index, IModel<Column> model) { return new OddEvenItem<Column>(id, index, model); } }; My data provider: public class ColumnSortableDataProvider extends SortableDataProvider<Column> { private static final long serialVersionUID = 1L; private List list = null; public ColumnSortableDataProvider(Table table, String sortProperty) { this.list = Arrays.asList(table.getColumns().toArray(new Column[0])); setSort(sortProperty, true); } public ColumnSortableDataProvider(List list, String sortProperty) { this.list = list; setSort(sortProperty, true); } @Override public Iterator iterator(int first, int count) { /* first - first row of data count - minimum number of elements to retrieve So this method returns an iterator capable of iterating over {first, first+count} items */ Iterator iterator = null; try { if(getSort() != null) { Collections.sort(list, new Comparator() { private static final long serialVersionUID = 1L; @Override public int compare(Column c1, Column c2) { int result=1; PropertyModel<Comparable> model1= new PropertyModel<Comparable>(c1, getSort().getProperty()); PropertyModel<Comparable> model2= new PropertyModel<Comparable>(c2, getSort().getProperty()); if(model1.getObject() == null && model2.getObject() == null) result = 0; else if(model1.getObject() == null) result = 1; else if(model2.getObject() == null) result = -1; else result = ((Comparable)model1.getObject()).compareTo(model2.getObject()); result = getSort().isAscending() ? result : -result; return result; } }); } if (list.size() (first+count)) iterator = list.subList(first, first+count).iterator(); else iterator = list.iterator(); } catch (Exception e) { e.printStackTrace(); } return iterator; } The problem is the following: - I click a column header to sort by that column. - I navigate to a different page - I click Back (or Forward if I do the opposite scenario) - Page has expired. It'd be nice to generate the page using PageParameters but I somehow need to intercept the sort event to do so. Any pointers would be greatly appreciated. Thanks a ton!! David

• Possible uncommitted transactions causing "System.Data.SqlClient.SqlException: Timeout expired" erro

  - by Michael

  My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read comments about increasing the timeout period but I've also read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application. I'll provide the code I'm working with and there is an IF statement in there that I was a little iffy about but it seemed like a reasonable thing to do. I'll just go over what's going on here, there is a list of objects to update or add into the database. New objects created in the application are given an ID of 0 while existing objects have their own ID's generated from the DB. If the user chooses to delete some objects, their IDs are stored in a separate list of Integers. Once the user is ready to save their changes, the two lists are passed into this method. By use of the IF statement, objects with ID of 0 are added (using the Add stored procedure) and those objects with non-zero IDs are updated (using the Update stored procedure). After all this, a FOR loop goes through all the integers in the "removal" list and uses the Delete stored procedure to remove them. A transaction is used for all this. Public Shared Sub UpdateSomethings(ByVal SomethingList As List(Of Something), ByVal RemovalList As List(Of Integer)) Using DBConnection As New SqlConnection(conn) DBConnection.Open() Dim MyTransaction As SqlTransaction MyTransaction = DBConnection.BeginTransaction() Try For Each SomethingItem As Something In SomethingList Using MyCommand As New SqlCommand() MyCommand.Connection = DBConnection If SomethingItem.ID > 0 Then MyCommand.CommandText = "UpdateSomething" Else MyCommand.CommandText = "AddSomething" End If MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters If MyCommand.CommandText = "UpdateSomething" Then .Add("@id", SqlDbType.Int).Value = SomethingItem.ID End If .Add("@stuff", SqlDbType.Varchar).Value = SomethingItem.Stuff End With MyCommand.ExecuteNonQuery() End Using Next For Each ID As Integer In RemovalList Using MyCommand As New SqlCommand("DeleteSomething", DBConnection) MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters .Add("@id", SqlDbType.Int).Value = ID End With MyCommand.ExecuteNonQuery() End Using Next MyTransaction.Commit() Catch ex As Exception MyTransaction.Rollback() 'Exception handling goes here End Try End Using End Sub There are three stored procedures used here as well as some looping so I can see how something can be holding everything up if the list is large enough. Other users can log in to the system at the same time just fine though. I'm using Visual Studio 2008 to debug and am using SQL Server 2000 for the DB.

• IPHONE DEVELOPMENT PROFILE EXPIRED - I TRIED EVERYTHING AND YES, I READ THE DOCS

  - by theiphoneguy

  I really combed this site and others. I read and re-read the related links here and the Apple docs. I'm sorry, but either I am obviously missing something right under my nose, or this Apple profile/certificate stuff is a bit convoluted. Here it is: I have a product in the App Store. I have updated it several times and users like it. My development profile recently expired just when I was improving the app for its next release. I can run the app in the simulator. I can compile and put the distribution build on my iPhone just fine. I went to the Apple portal and renewed the development profile. I downloaded it and installed it in Xcode. I see it in the Organize window. I see it on my iPhone. I CANNOT put the debug build on my iPhone to debug or run with Instruments. The message is that either there is not a valid signed profile or it is untrusted. I subsequently tried to download and install the certificate to my Mac's keychain. Still no success. I checked the code signing section of Project settings and also for the target and the root. All appears to indicate that it is using the expected development profile for debug. Yes, I had deleted the old profile from my iPhone, from the Organizer. I cleaned the Xcode cache and all targets. I have done all of this several times and in varying sequences to try to cover every possibility. I am ready to do anything to be able to debug with Instruments in order to check for leaks or high memory usage. Even though the distribution compile runs fine on my iPhone and plays well with other running processes, I will not release anything without a leaks/memory test. Any ideas will be appreciated. If I missed something obvious, please forgive me - it was not due to just posting a question without searching for similar postings. Thanks!

• How to find an specific key/value (property list)

  - by Bob Rivers

  Hi, I'm learning cocoa/objective-c. Right now I'm dealing with key/value coding. After reading Aaron's book and other sources, I thought that I was able to left the simple examples and try a complex one... I'm trying read iTunes property list (iTunes Music Library.xml). I would like to retrieve the tracks held by an specific playlist. Probably everybody knows it, but bellow I put a piece of the xml: <plist version="1.0"> <dict> <key>Major Version</key><integer>1</integer> ... <key>Playlists</key> <array> <dict> <key>Name</key><string>Library</string> ... <key>Playlist Items</key> <array> <dict> <key>Track ID</key><integer>10281</integer> </dict> ... </array> </dict> <dict> ... </dict> </array> </dict> </plist> As you can see, the playlists are stored as dictionaries inside an array, and the key that identifies it is inside it, not as a <key> preceding it. The problem is that I'm not able to figure out how to search for a key that is inside another one. With the following code I can find the the array in which the playlists are stored, but how to find an specific <dict>? NSDictionary *rootDict = [[NSDictionary alloc] initWithContentsOfFile:file]; NSArray *playlists = [rootDict objectForKey:@"Playlists"]; Here at Stackoverflow I found this post, but I'm not sure if iterate over the array and test it is a good idea. I'm quite sure that I could use valueForKeyPath, but I'm unable to figure out how to do it. Any help is welcome. TIA, Bob

I have added the appropriate public key afterwards to the ~/.ssh/authorized_keys I can also ssh to the node, but as I have not been asked to give it a user name or password or set up any sort of account, I cannot manually ssh into the node. The setup of the node is all handled by maas server. It seems like a simple error of looking at the wrong key or looking in the wrong places, only other suggestions I can find are to destroy the environment and rebuild (but that didn't work umpteen times now) or leave it to build the instance once the node has powered up, but I have left for a few hours, and left overnight to build with no luck.

• Showplan Operator of the Week – BookMark/Key Lookup

  Fabiano continues in his mission to describe the major Showplan Operators used by SQL Server's Query Optimiser. This week he meets a star, the Key Lookup, a stalwart performer, but most famous for its role in ill-performing queries where an index does not 'cover' the data required to execute the query. If you understand why, and in what circumstances, key lookups are slow, it helps greatly with optimising query performance.

• Ubuntu 14.04 key arrow up is being pressed by itself

  - by Margo Nikolopoulou

  Keyboard's up arrow key is keep pressing itself every few seconds. I tried to install Ubuntu 14.04 via boot cd, even before installation the arrow key was being pressed by itself. I tried to use Ubuntu first without installing it and then tried to install it from there, the issue seemed to be fixed. I was using the PC for months until out of the blue the issue came back. IT IS NOT A HARDWARE ISSUE! Thank you in advance.

• Setting to protect gnome-terminal from key logging

  - by yanychar

  Looks like it is easy to log keystrokes of all processes of the same user. A basic keylogger is 'xinput'. xinput test-xi2 The command generates log of all key-presses. Unfortunately, this includes passwords in gnome-terminal. Googling suggested that grabbing keyboard may prevent other windows from capturing key strokes. Is there a way to prevent XI2 logging in gnome-terminal? Or is there an X terminal that has this feature?

• Showplan Operator of the Week – BookMark/Key Lookup

  Fabiano continues in his mission to describe the major Showplan Operators used by SQL Server's Query Optimiser. This week he meets a star, the Key Lookup, a stalwart performer, but most famous for its role in ill-performing queries where an index does not 'cover' the data required to execute the query. If you understand why, and in what circumstances, key lookups are slow, it helps greatly with optimising query performance.

• Disable keyboard suspend key

  - by Jcubed

  How do I disable my keyboard's suspend key? My keyboard (Logitech k800) has a key for powering off the pc, in Ubuntu its working as a suspend button. I've tried assigning another shortcut to that button, but its not preventing the computer from sleeping. Also, I'm not sure if there's a difference between suspend and sleep, but it appears to be turning the computer completely off, but when I start it back up it resumes where it left off.

• Reinstall Acer OEM Windows 8, Windows 8 Recovery for Acer Aspire V5 122p

  - by stwindr

  My Acer Aspire V5-122P-61456G50NSS, model - MS2377, has crashed all together. It came preloaded with Windows 8 and I upgraded to windows 8.1 3-4 days before crash. Unfortunately I did not make any recovery media before the crash. While accessing the eRecovery on Acer store with my PC's serial no. it says nor RCD available for this. I tried recovery by loading recovery manager (Left Alt + F10) Various other advanced startup options (like holding shift key while turning on or pressing F8 key) returns nothing but no luck. However I am able to enter BIOS. After doing research on above condition on various PC forums, now my questions: I read that a 'Windows Recovery Drive' can be made on any PC running Windows 8 and could be used to repair another PC. Does anybody in SuperUser community have that (or a link to download the same from somewhere? as I'm unable to find anybody running windows 8 among my friends). I downloaded a window 8 Pro ISO and made a bootable USB. I was able to go to 'Repair Your Computer' option and after going to 'Reset your PC' option found that my recovery partition has gone/missing. I tried all options available but no luck. Then I tried to install with that Windows 8 Pro ISO but got message: "The product key entered does not match any of the Windows images available for installation. Enter a different product key". before this message I did not got any form to fill product key! Does this mean that the installer was picking up the key from BIOS (OEM Key)? and may be the installation did not succeeded because OEM Windows version was Window 8 and I was trying to install Windows 8 Pro. If that is the case then, could somebody please send me link to download an Windows 8 ISO? I am helpless and couldn't find anywhere on internet (without having to pay for a new key, but I should not pay as the installer will use OEM key).

• Finding Bluetooth link key in Windows 7, to double pair a device on dualboot computer

  - by Ilari Kajaste

  How can I dig up the Bluetooth link key for a paired device in Windows 7? Is this something that is dependent on the Bluetooth stack I'm using (Toshiba), or is there a generic place to store these in Windows 7? Note: I'm not talking about the six-digit code usually typed by the user during pairing - that is worthless since it's discarded after pairing process. What I mean is the 128-bit link key that the devices exchange during pairing, and use thereafter to encrypt all their Bluetooth traffic. Background: I dualboot Windows 7 / Ubuntu on my laptop, and I would like to have my phone paired to both OS's. Since the dualbooting computer has only one Bluetooth adapter and thus only one Bluetooth address, I cannot do two pairings to the phone, since on the second pairing (Windows) the phone just replaces the previous pairing (Linux) to the same Bluetooth address. A thread on Ubuntu forums pointed me to what I have to do - pair first on Linux, then on Windows, and then replace the link key on Linux side with the one Windows negotiated. I can find the Linux side pairing key from /var/lib/Bluetooth/[BD_ADDR]/linkkeys - no problems there. However, on Windows side I can't find the key. According to the forum post, on Windows side the key should be in SYSTEM\ControlSet002\services\BTHPORT\Parameters\Keys\[BD_ADDR] but while that registry key does exist, it has no subkeys. (And a similar registry path in ControlSet001 didn't have any subkeys either.) One thing I've been instructed to do is to capture all events during pairing with Sysinternals Process Monitor. I did this, but I haven't been able to find any useful information from the captured events, not even by exporting the data to a huge XML and grepping that with the BD_ADDRs (with or without colons). So how could I find the link key for a paired device in Windows 7? Some reference information: Wikipedia: Bluetooth, Security Now: Bluetooth security
