• Is my dns server being attacked? And what should I do about it?

  - by Mnebuerquo

  I've been having some intermittent dns problems with a web server, where certain isp's dns servers don't have my hostnames in cache and fail to look them up. At the same time, queries to opendns for those hostnames resolve correctly. It's intermittent, and it always works fine for me, so it's hard to identify the problem when someone reports connectivity problems to my site. In trying to figure this out, I've been looking at my logs to see if there are any errors I should know about. I found thousands of the following messages in my logs, from different ip's, but all requesting similar dns records: May 12 11:42:13 localhost named[26399]: client 94.76.107.2#36141: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#29075: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#47924: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#4727: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#16153: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#40267: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63507: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63721: query (cache) 'burningpianos.org/MX/IN' denied May 12 11:43:36 localhost named[26399]: client 82.209.240.241#3537: query (cache) 'burningpianos.com/MX/IN' denied I've read of Dan Kaminski's dns cache poisoning vulnerability, and I'm wondering if these log records are an attempt by some evildoer to attack my dns server. There are thousands of records in my logs, all requesting "burningpianos", some for com and some for org, most looking for an mx record. There are requests from multiple ip's, but each ip will request hundreds of times per day. So this smells to me like an attack. What is the defense against this?

• How to change System default language on GNOME3?

  - by Vor

  I just installed GNOME3 on my Ubuntu. Everything worked fine till I restarted computer. Then I received a message if I want to change folders name to some other (different language, don't know what is this, but looks like Chinese). I pressed, 'keep old names' but it still changed all my folder names! And also the rest of the names. (like settings, and all that staff). So if you can give me the direction on where to click (cause all English names changed to non-English) and I simply don't know what does any of them means!

• Controller Index methods with different signatures

  - by Narsil

  I am trying to get my URLs in files/id format. I am guessing I should have two Index methods in my controller, one with a parameter and one with not. But I get this error message in browser below. Anyway here is my controller methods: public ActionResult Index() { return Content("Index "); } // // GET: /Files/5 public ActionResult Index(int id) { File file = fileRepository.GetFile(id); if (file == null) return Content("Not Found"); return Content(file.FileID.ToString()); } Error: Server Error in '/' Application.

• Stuck removing ffmpeg from system due to package problems

  - by Michiel

  I'd be very grateful to get a bit of support on the following situation: Using Ubuntu 12.04, and I used the PPA of Jon Severinson for ffmpeg. I had a problem playing movies with mplayer, so I decided to remove the PPA and try to use libav only after I read this article about libav vs ffmpeg. I first removed the PPA from the list, then apt-get update, etc. But I couldn't remove ffmpeg due to dependency-errors and got stuck in what seemed some kind of loop. Then I found a suggestion here. I followed the steps, and ended up force-removing libavcodec-extra-53. Because, apparently that was "what got stuff moving again". At the moment I can't. Now Ubuntu is reporting a broken package (BrokenCount 0).

• Python 3 with the range function

  - by Leif Andersen

  I can type in the following code in the terminal, and it works: for i in range(5): print(i) And it will print: 0 1 2 3 4 as expected. However, I tried to write a script that does a similar thing: print(current_chunk.data) read_chunk(file, current_chunk) numVerts, numFaces, numEdges = current_chunk.data print(current_chunk.data) print(numVerts) for vertex in range(numVerts): print("Hello World") current_chunk.data is gained from the following method: def read_chunk(file, chunk): line = file.readline() while line.startswith('#'): line = file.readline() chunk.data = line.split() The output for this is: ['OFF'] ['490', '518', '0'] 490 Traceback (most recent call last): File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 88, in execute load_off(self.properties.path, context) File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 68, in load_off for vertex in range(numVerts): TypeError: 'str' object cannot be interpreted as an integer So, why isn't it spitting out Hello World 490 times? Or is the 490 being thought of as a string? I opened the file like this: def load_off(filename, context): file = open(filename, 'r')

• SBS 2003 no network connection and acting strangely a bunch of Event ID 13568

  - by JMan78

  I've got an SBS 2003 Standard server and it was running fine until earlier today when it was rebooted, after the reboot it has no network connection, I can't seem to right click on a lot of stuff and get dialog boxes, I can't launch IE, it's acting extremely strange. We are dead in the water at this point. I checked the event logs and noticed we're getting a ton of Event ID's 13568. I thought it was a Journal Wrap error, and while I was going to try to fix it using this article: http://support.microsoft.com/kb/290762 I can't even do that because after I set the D4 value, then went to restart NTFRS from command prompt and I got the following: System Error 1059 has occurred. Circular service dependency was specified. That is where I'm at and haven't been able to figure anything else out. ALso, I've posted this on EE, there are some screens of event logs and such there: http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/SBS_Small_Business_Server/Q_27969593.html

• More goodness: Scrum for Team System Migration Tool from EMC

  - by Enrique Lima

  I have always liked how SfTS works, and the functionality it offers.  In an earlier assessment I wrote of their toolset, the only issue I had encountered was the migration of environment that had been created and worked on for a while in the TFS 2008 world using SfTS 2.0 to the TFS 2010 SfTS 3.0.  There were several elements (Work Items and such) that were not moving correctly. Anyway, that is now in the past! Congratulations to Crispin Parker and Team for the release of the Migration Tool. You can see the release information and link to download here … http://www.scrumforteamsystem.com/main-news/sfts-v3-migration-tool-goes-gold

• Need help manipulating WAV (RIFF) Files at a byte level

  - by Eric

  I'm writing an an application in C# that will record audio files (*.wav) and automatically tag and name them. Wave files are RIFF files (like AVI) which can contain meta data chunks in addition to the waveform data chunks. So now I'm trying to figure out how to read and write the RIFF meta data to and from recorded wave files. I'm using NAudio for recording the files, and asked on their forums as well on SO for way to read and write RIFF tags. While I received a number of good answers, none of the solutions allowed for reading and writing RIFF chunks as easily as I would like. But more importantly I have very little experience dealing with files at a byte level, and think this could be a good opportunity to learn. So now I want to try writing my own class(es) that can read in a RIFF file and allow meta data to be read, and written from the file. I've used streams in C#, but always with the entire stream at once. So now I'm little lost that I have to consider a file byte by byte. Specifically how would I go about removing or inserting bytes to and from the middle of a file? I've tried reading a file through a FileStream into a byte array (byte[]) as shown in the code below. System.IO.FileStream waveFileStream = System.IO.File.OpenRead(@"C:\sound.wav"); byte[] waveBytes = new byte[waveFileStream.Length]; waveFileStream.Read(waveBytes, 0, waveBytes.Length); And I could see through the Visual Studio debugger that the first four byte are the RIFF header of the file. But arrays are a pain to deal with when performing actions that change their size like inserting or removing values. So I was thinking I could then to the byte[] into a List like this. List<byte> list = waveBytes.ToList<byte>(); Which would make any manipulation of the file byte by byte a whole lot easier, but I'm worried I might be missing something like a class in the System.IO name-space that would make all this even easier. Am I on the right track, or is there a better way to do this? I should also mention that I'm not hugely concerned with performance, and would prefer not to deal with pointers or unsafe code blocks like this guy. If it helps at all here is a good article on the RIFF/WAV file format.

• Adding dynamic business logic/business process checks to a system

  - by Jordan Reiter

  I'm wondering if there is a good extant pattern (language here is Python/Django but also interested on the more abstract level) for creating a business logic layer that can be created without coding. For example, suppose that a house rental should only be available during a specific time. A coder might create the following class: from bizlogic import rules, LogicRule from orders.models import Order class BeachHouseAvailable(LogicRule): def check(self, reservation): house = reservation.house_reserved if not (house.earliest_available < reservation.starts < house.latest_available ) raise RuleViolationWhen("Beach house is available only between %s and %s" % (house.earliest_available, house.latest_available)) return True rules.add(Order, BeachHouseAvailable, name="BeachHouse Available") This is fine, but I don't want to have to code something like this each time a new rule is needed. I'd like to create something dynamic, ideally something that can be stored in a database. The thing is, it would have to be flexible enough to encompass a wide variety of rules: avoiding duplicates/overlaps (to continue the example "You already have a reservation for this time/location") logic rules ("You can't rent a house to yourself", "This house is in a different place from your chosen destination") sanity tests ("You've set a rental price that's 10x the normal rate. Are you sure this is the right price?" Things like that. Before I recreate the wheel, I'm wondering if there are already methods out there for doing something like this.

• syslogd: Logfile format (not configuration format)

  Hi, I'd like to parse logfiles. Is the logfile format of syslogd the same for all systems? On my system (Debian Lenny), it's: Mar 7 04:22:40 my-host-name ... (I'm not much interested in the ... part) Can I rely on this? And is there maybe some more-or-less official description? The manpage of syslogd describes the config format, but not the logfile format. Ideally, the description would give the fields official names like (date, time, host, entry) or (datetime, hostname, message). Maybe additionally some regular expressions. I'd like to use the names and regexes in my script, to avoid an unnecessary deviation from the standard, and to make sure, that the script runs everywhere. Thanks Chris

• Installing Forms and Reports on a development system

  - by Duncan Mills

  By popular demand I've resurrected / updated one of the old blog postings from Jan Carlin's Blog on GroundSide here. A recent (lengthy) post on the Forms forums chronicles the problems some of you have had installing F&R on a development machine. See the link in the headline of this post for the main one. When installing, here are some points to bear in mind: Download and install Weblogic Server first. http://www.oracle.com/technology/software/products/middleware/index.htmlFind the Forms and Reports (and Disco and Portal) zip files here. Download them to the desktop (or some other temporary directory of your choosing). Unzip both of the two zip files into the same new directory (maybe called 'stage') and check that you have 4 directories in the stage dir when you are finished unzipping: 'Disk1', 'Disk2', 'Disk3' and 'Disk4'. These folders are specified in the zip file structure and must be preserved for the setup executable to work. If you use WinZip and have a right click menu option that say "Extract to here", use that by right click-dragging the zip file onto the newly created directory. Don't use the "Extract to folder %HOME%\Desktop\ofm_pfrd...disk_1of2" option. That will get you into the trouble that was reported early in this thread. Free up as much memory as you can. Stop services and background processes and virus scanners and databases (you don't need a DB to install Forms) and other things lurking about on your machine. You can restart them when the install is done. Around 1.5 GB free real memory should do it. If it doesn't, free up more if you can. Don't change the swap space unless you know what you are doing. Let Windows handle it. A 1 GB machine will likely not be enough. You will likely need at least 2GB of RAM.Start the install with setup.exe from the 'Disk1' directoryChoose the Install and Configure option unless you have a good reason not to.Choose a unique instance name even if you deinstalled and removed the last install. I suggest using 'asinst_20090722_1' (today's date in ISO format with a running incremented number at the end if you install more than two times on a particular day).Unselect Portal and Discoverer and select the Builders you want.Unselect WebCacheUnselect OHS.Unselect the single sign-on option Check for any failures and choose the retry option if any occur. If that doesn't fix the problem, call Oracle Customer Support .

• What is node.js?

  - by Jeffrey

  I don't fully get what node.js is all about. Maybe it's because I am mainly a web based business app developer. Can someone please explain what it is and the use of it? Thanks. My understanding so far is that: The programming model is event driven, especially the way it handles IO. It uses javascript and the parser is V8. It can be easily used to create concurrent server apps. Are my understandings correct? If yes, then what are the benefits of evented IO, is it just more for the concurrency stuffs? Also is the direction of node.js to become a framework like, javascript based (v8 based) programming model?

• Why does ObservableCollection throws an exception when being modified?

  - by Oliver Hanappi

  Hi! My application uses a WPF DataGrid. One of the columns is a template column that containts a combobox bound to an ObservableCollection of the entity which feeds the row. When I add a value to the ObservableCollection, a NullReferenceException is thrown. Has anybody an idea why this happens? Here is the stacktrace of the exception: at MS.Internal.Data.PropertyPathWorker.DetermineWhetherDBNullIsValid() at MS.Internal.Data.PropertyPathWorker.get_IsDBNullValidForUpdate() at MS.Internal.Data.ClrBindingWorker.get_IsDBNullValidForUpdate() at System.Windows.Data.BindingExpression.ConvertProposedValue(Object value) at System.Windows.Data.BindingExpressionBase.UpdateValue() at System.Windows.Data.BindingExpression.Update(Boolean synchronous) at System.Windows.Data.BindingExpressionBase.Dirty() at System.Windows.Data.BindingExpression.SetValue(DependencyObject d, DependencyProperty dp, Object value) at System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata metadata, Boolean coerceWithDeferredReference, OperationType operationType, Boolean isInternal) at System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value) at System.Windows.Controls.Primitives.Selector.UpdatePublicSelectionProperties() at System.Windows.Controls.Primitives.Selector.SelectionChanger.End() at System.Windows.Controls.Primitives.Selector.OnItemsChanged(NotifyCollectionChangedEventArgs e) at System.Windows.Controls.ItemsControl.OnItemCollectionChanged(Object sender, NotifyCollectionChangedEventArgs e) at System.Collections.Specialized.NotifyCollectionChangedEventHandler.Invoke(Object sender, NotifyCollectionChangedEventArgs e) at System.Windows.Data.CollectionView.OnCollectionChanged(NotifyCollectionChangedEventArgs args) at System.Windows.Controls.ItemCollection.System.Windows.IWeakEventListener.ReceiveWeakEvent(Type managerType, Object sender, EventArgs e) at System.Windows.WeakEventManager.DeliverEventToList(Object sender, EventArgs args, ListenerList list) at System.Windows.WeakEventManager.DeliverEvent(Object sender, EventArgs args) at System.Collections.Specialized.CollectionChangedEventManager.OnCollectionChanged(Object sender, NotifyCollectionChangedEventArgs args) at System.Windows.Data.CollectionView.OnCollectionChanged(NotifyCollectionChangedEventArgs args) at System.Windows.Data.ListCollectionView.ProcessCollectionChangedWithAdjustedIndex(NotifyCollectionChangedEventArgs args, Int32 adjustedOldIndex, Int32 adjustedNewIndex) at System.Windows.Data.ListCollectionView.ProcessCollectionChanged(NotifyCollectionChangedEventArgs args) at System.Windows.Data.CollectionView.OnCollectionChanged(Object sender, NotifyCollectionChangedEventArgs args) at System.Collections.ObjectModel.ObservableCollection`1.OnCollectionChanged(NotifyCollectionChangedEventArgs e) at System.Collections.ObjectModel.ObservableCollection`1.InsertItem(Int32 index, T item) at System.Collections.ObjectModel.Collection`1.Add(T item) at ORF.PersonBook.IdentityModule.Model.SubsidiaryModel.AddRoom(RoomModel room) in C:\Project\Phoenix\Development\src\ORF.PersonBook.IdentityModule\Model\SubsidiaryModel.cs:line 127

• An XEvent a Day (22 of 31) – The Future – fn_dblog() No More? Tracking Transaction Log Activity in Denali

  - by Jonathan Kehayias

  I bet that made you look didn’t it?  Worry not, fn_dblog() still exists in SQL Server Denali, and I plan on using it to validate the information being returned by a new Event in SQL Server Denali CTP1, sqlerver.transaction_log, which brings with it the ability to correlate specific transaction log entries to the operations that actually caused them to occur. There is no greater source of information about the transaction log in SQL Server than Paul Randal’s blog category Transaction Log . ...(read more)

• Can an issue tracking system be distributed?

  - by Klaim

  I was thinking about issue tracking software like Redmine, Trac or even the one that is in Fossil and something hit me: Is there a reason why Redmine and Trac are not possible to be distributed? Or maybe it's possible and I just don't know how it's possible? If it's not possible, why? By distributed I mean like Facebook or Google or other applications that effectively runs on multiple hardware a the same time but share data.

• Package management fails in update-manager with gzip problems and compilation errors. U12.04LTS

  - by HarveyP

  Similar to but not the same as Package management system corrupted. Cannot install or remove packages. U12.04LTS (an earlier problem) with package management system. Followed all of L. D. James suggestions in his answer to no avail. This time as well as the gzip error I am also getting compilation errors. The difference may be due to a lack of compilation in my earlier problem so it may be the same error. The packages concerned are enumerated in the output from update-manager below. Also included below that is the output from apt-get -f install apt-get autoremove gives same output. Tried update without SSL updates - 9 to install and got "Unhandled Error in aptdaemon". Output number 3 below. One at a time - output 4 - is for firefox, first in the list of packages. Falls over at libssl1.0.0 despite deselection of it from update ... Tried apt-get install --reinstall dpkg which succeeded, apt-get install --reinstall tar and apt-get install --reinstall gzip both of which failed at libssl1.0.0 as ever. (as suggested by Subv3rsion elsewhere in this forum) Now cannot apt-get update with complete success even after changing server and apt-get clean - output number 5 below ... 1).

• Tomboy error while tring to sync with Ubuntu one; Can anyone help?

  - by Michael Chapman

  So I'm sure you've heard the song before, but after trying to sync my notes with Ubuntu One(on 10.10 AMD64) I get "Could not synchronize notes. Check the details below and try again." Of course the problem is that there are no details and trying again doesn't help. So I ran tomboy -debug and compared my error to any thing I could find about similar problems (such as the post here) but found nothing useful. Any way here's my first error, I got this using preferencessynchronizationUbuntu_one [ERROR 21:08:42.271] Synchronization failed with the following exception: String was not recognized as a valid DateTime. at System.DateTime.Parse (System.String s, IFormatProvider provider, DateTimeStyles styles) [0x00000] in <filename unknown>:0 at System.DateTime.Parse (System.String s, IFormatProvider provider) [0x00000] in <filename unknown>:0 at System.DateTime.Parse (System.String s) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.NoteInfo.ParseJson (Hyena.Json.JsonObject jsonObj) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.ParseJsonNoteArray (Hyena.Json.JsonArray jsonArray) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.ParseJsonNotes (System.String jsonString, System.Nullable`1& latestSyncRevision) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.GetNotes (Boolean includeContent, Int32 sinceRevision, System.Nullable`1& latestSyncRevision) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.WebSyncServer.GetNoteUpdatesSince (Int32 revision) [0x00000] in <filename unknown>:0 at Tomboy.Sync.SyncManager.SynchronizationThread () [0x00000] in <filename unknown>:0 The next thing I tried was using preferencessynchronizationtomboy_web with the default 'http://one.ubuntu.com/notes/' and got the same error plus one more.

The only other Thing I have noticed is that under systempreferencesubuntu one services, "Notes" is not listed as a service. I don't know if this is normal or not. Thanks for any help and please let me know if anything is confusing.

• How do You Get a Specific Value From a System.Data.DataTable Object?

  - by Giffyguy

  I'm a low-level algorithm programmer, and databases are not really my thing - so this'll be a n00b question if ever there was one. I'm running a simple SELECT query through our development team's DAO. The DAO returns a System.Data.DataTable object containing the results of the query. This is all working fine so far. The problem I have run into now: I need to pull a value out of one of the fields of the first row in the resulting DataTable - and I have no idea where to even start. Microsoft is so confusing about this! Arrrg! Any advice would be appreciated. I'm not providing any code samples, because I believe that context is unnecessary here. I'm assuming that all DataTable objects work the same way, no matter how you run your queries - and therefore any additional information would just make this more confusing for everyone.

• Record management system java web framework

  - by Kamil Tomšík

  We're currently reconsidering technologies and frameworks to get more agile with "simple" RMS CRUD-based projects. In short, short-living things like this Right now we have a custom extension on top of SmartGWT but after some time it has proven not to be flexible enough. I also personally dislike the java-js compilation process and the whole GWT codebase. Not only is the design ugly, it also makes certain low-level js things very complicated if not completely impossible. So what I'm looking for is: closest to web as possible, like JSF or possibly Tapestry, it is very important to be able get "low" and weave framework if necessary. Happens more often than we thought. datagrid capable - Ext.js & PrimeFaces looks pretty good, Vaadin does too. db-schema generators (optional, no matter in which way) If it were only on me, I'd probably stick to Ext.js + custom rest-based java solution, possibly generated from database schema (not sure about concrete tooling yet). I only have experience with vanilla Ext.js, vanilla GWT and JSF 2.0 / Seam, so it hard for me to judge or even propose other frameworks. What would be your proposition? What are the problems you've faced? What was your solution and how hard do you think it was to deal with them in "big picture"?

• IVR-style dialog system

  - by unbeli

  I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

• How to mount nexus 7 file system to view files from command line

  - by knotech

  Just got a Nexus 7, switched MTP on and plugged it in. It pops right up in nautilus, is titled Nexus 7, and lets me browse all of the files. However, on the command line, it's simply listed as /media/usbdrive and when I try to list the files, nothing comes up. Do I have to manually mount it in order to navigate the files from the command line? And why is it that nautilus recognizes it, and has access immediately, but I can't get at it from the command line?

• Find a Faster DNS Server with Namebench

  - by Mysticgeek

  One way to speed up your Internet browsing experience is using a faster DNS server. Today we take a look at Namebench, which will compare your current DNS server against others out there, and help you find a faster one. Namebench Download the file and run the executable (link below). Namebench starts up and will include the current DNS server you have configured on your system. In this example we’re behind a router and using the DNS server from the ISP. Include the global DNS providers and the best available regional DNS server, then start the Benchmark. The test starts to run and you’ll see the queries it’s running through. The benchmark takes about 5-10 minutes to complete. After it’s complete you’ll get a report of the results. Based on its findings, it will show you what DNS server is fastest for your system. It also displays different types of graphs so you can get a better feel for the different results. You can export the results to a .csv file as well so you can present the results in Excel. Conclusion This is a free project that is in continuing development, so results might not be perfect, and there may be more features added in the future. If you’re looking for a method to help find a faster DNS server for your system, Namebench is a cool free utility to help you out. If you’re looking for a public DNS server that is customizable and includes filters, you might want to check out our article on helping to protect your kids from questionable content using OpenDNS.
