  • High Jitter in NTP and poll value never goes above 128

    - by Aseem
    I have a lot of servers syncing to the same NTP servers (4). Not every server is in the same LAN. Some are 3 hops away from the NTP servers and some are 6 hops away. On couple of servers I see that the poll value never touches the 1024 mark and the jitter value is in double digits. Could it be due to the system hardware? These are windows servers (physical) and require as accurate time as possible. Please advice what I should do. Some of the stats that I collected manually from the bad box (which is 6 hops away from the ntp servers) C:\Program Files (x86)\NTP>ntpq -p -n remote refid st t when poll reach delay offset jitter ============================================================================== +*.*.*.25 *.*.*.233 2 u 12 128 377 1.210 -12.579 14.913 +*.*.*.26 *.*.*.233 2 u 96 128 377 1.067 -2.235 9.885 **.*.*.27 *.*.*.233 2 u 24 128 377 1.038 -7.569 11.178 +*.*.*.28 *.*.*.233 2 u 49 128 377 1.288 -11.058 14.544 remote refid st t when poll reach delay offset jitter ============================================================================== +*.*.*.25 *.*.*.233 2 u 124 128 377 0.614 -6.212 5.329 +*.*.*.26 *.*.*.233 2 u 93 128 377 0.910 -9.431 3.111 +*.*.*.27 *.*.*.233 2 u 1 128 377 0.824 -7.428 3.129 **.*.*.28 *.*.*.233 2 u 84 128 377 1.503 -8.230 3.511 remote refid st t when poll reach delay offset jitter ============================================================================== **.*.*.25 *.*.*.233 2 u 117 128 377 1.235 -4.084 11.405 +*.*.*.26 *.*.*.233 2 u 96 128 377 1.335 -11.813 13.130 +*.*.*.27 *.*.*.233 2 u 130 128 377 1.549 -14.036 16.381 -*.*.*.28 *.*.*.233 2 u 79 128 377 1.258 13.395 22.203 remote refid st t when poll reach delay offset jitter ============================================================================== **.*.*.25 *.*.*.233 2 u 88 128 377 1.235 -4.084 14.068 +*.*.*.26 *.*.*.233 2 u 63 128 377 1.335 -11.813 17.086 +*.*.*.27 *.*.*.233 2 u 103 128 377 1.549 -14.036 20.691 -*.*.*.28 *.*.*.233 2 u 47 128 377 1.258 13.395 20.231 remote refid st t when poll reach delay offset jitter ============================================================================== +*.*.*.25 *.*.*.233 2 u 47 64 377 0.652 -15.805 14.077 **.*.*.26 *.*.*.233 2 u 11 64 377 1.013 -14.423 11.375 -*.*.*.27 *.*.*.233 2 u 63 64 377 0.765 -2.030 7.680 +*.*.*.28 *.*.*.233 2 u 4 64 377 1.191 -17.980 14.393 remote refid st t when poll reach delay offset jitter ============================================================================== -*.*.*.25 *.*.*.233 2 u 3 128 377 1.576 18.665 21.999 +*.*.*.26 *.*.*.233 2 u 73 128 377 0.637 -5.012 14.405 **.*.*.27 *.*.*.233 2 u 127 128 377 0.272 -8.237 14.438 +*.*.*.28 *.*.*.233 2 u 123 128 377 1.190 -14.383 18.875 C:\Program Files (x86)\NTP>ntpdc -c loopinfo offset: -0.016430 s frequency: 7.106 ppm poll adjust: 18 watchdog timer: 133 s offset: -0.016430 s frequency: 7.106 ppm poll adjust: 18 watchdog timer: 341 s offset: -0.000149 s frequency: 6.645 ppm poll adjust: 0 watchdog timer: 383 s offset: 0.015735 s frequency: 6.725 ppm poll adjust: 7 watchdog timer: 577 s offset: -0.010331 s frequency: 6.748 ppm poll adjust: 21 watchdog timer: 567 s offset: -0.009427 s frequency: 6.687 ppm poll adjust: 28 watchdog timer: 301 s offset: -0.007361 s frequency: 6.612 ppm poll adjust: 30 watchdog timer: 155 s offset: -0.008106 s frequency: 4.358 ppm poll adjust: 30 watchdog timer: 291 s NTP.conf # NTP configuration file # Use drift file driftfile "C:\Program Files (x86)\NTP\ntp.drift" # Logs statistics loopstats peerstats clockstats statsdir "C:\Program Files (x86)\NTP\logs\" # directory for statistics files filegen peerstats file peerstats type day enable filegen loopstats file loopstats type day enable filegen clockstats file clockstats type day enable logfile "C:\Program Files (x86)\NTP\logs\syslog.txt" # Use specific NTP servers server *.*.*.25 minpoll 4 maxpoll 7 iburst server *.*.*.26 minpoll 4 maxpoll 7 iburst server *.*.*.27 minpoll 4 maxpoll 7 iburst server *.*.*.28 minpoll 4 maxpoll 7 iburst

  • EC2: is an instance's public DNS stable? Can I rely on it not changing?

    - by Aseem Kishore
    I'm new to Amazon EC2. I've launched my first instance, and am using it as a web server. I see that it has a public DNS (a public URL), e.g.: ec2-123-45-6-789.compute-1.amazonaws.com I can successfully go to this server in my browser, hit it via cURL, etc. I want to use this web server for a back-end service in an app I'm building, so I placed this URL in my app's config, and it works great. But when I manually stop and re-started my instance, I see that the public DNS changes! I've read that this happens when you explicitly stop and re-start, but doesn't happen if you just "reboot". I don't plan on explicitly stopping and re-starting this server ever, but my question is: will this public DNS ever change on its own for any reason? E.g. if the machine abnormally crashes, or whatever. In other words, is it safe to ship an app that's wired to this URL? Thanks!

  • DataView.RowFilter Vs DataTable.Select() vs DataTable.Rows.Find()

    - by Aseem Gautam
    Considering the code below: Dataview someView = new DataView(sometable) someView.RowFilter = someFilter; if(someView.count > 0) { …. } Quite a number of articles which say Datatable.Select() is better than using DataViews, but these are prior to VS2008. Solved: The Mystery of DataView's Poor Performance with Large Recordsets Array of DataRecord vs. DataView: A Dramatic Difference in Performance Googling on this topic I found some articles/forum topics which mention Datatable.Select() itself is quite buggy(not sure on this) and underperforms in various scenarios. On this(Best Practices ADO.NET) topic on msdn it is suggested that if there is primary key defined on a datatable the findrows() or find() methods should be used insted of Datatable.Select(). This article here (.NET 1.1) benchmarks all the three approaches plus a couple more. But this is for version 1.1 so not sure if these are valid still now. Accroding to this DataRowCollection.Find() outperforms all approaches and Datatable.Select() outperforms DataView.RowFilter. So I am quite confused on what might be the best approach on finding rows in a datatable. Or there is no single good way to do this, multiple solutions exist depending upon the scenario?

  • Why isn't jQuery automatically appending the JSONP callback?

    - by Aseem Kishore
    The $.getJSON() documentation states: If the specified URL is on a remote server, the request is treated as JSONP instead. See the discussion of the jsonp data type in $.ajax() for more details. The $.ajax() documentation for the jsonp data type states (emphasis mine): Loads in a JSON block using JSONP. Will add an extra "?callback=?" to the end of your URL to specify the callback. So it seems that if I call $.getJSON() with a cross-domain URL, the extra "callback=?" parameter should automatically get added. (Other parts of the documentation support this interpretation.) However, I'm not seeing that behavior. If I don't add the "callback=?" explicitly, jQuery incorrectly makes an XMLHttpRequest (which returns null data since I can't read the response cross-domain). If I do add it explicitly, jQuery correctly makes a <script> request. Here's an example: var URL = "http://www.geonames.org/postalCodeLookupJSON" + "?postalcode=10504&country=US"; function alertResponse(data, status) { alert("data: " + data + ", status: " + status); } $.getJSON(URL, alertResponse); // alerts "data: null, status: success" $.getJSON(URL + "&callback=?", alertResponse); // alerts "data: [object Object], status: undefined" So what's going on? Am I misunderstanding the documentation or forgetting something? It goes without saying that this isn't a huge deal, but I'm creating a web API and I purposely set the callback parameter to "callback" in the hopes of tailoring it nicely to jQuery usage. Thanks!

  • I/O between AIR client using Native process and executable java .jar

    - by aseem behl
    I am using Adobe AIR 2.0 native process API to launch a java executable jar. I/O is handled by writing to the input stream of the java process and reading from the output stream. The application is event based where several events are fired from the server. We catch these events in java code, handle them and write the output to the outputstream using the synchronized static method below. public class ReaderWriter { static Logger logger = Logger.getLogger(ReaderWriter.class); public synchronized static void writeToAir(String output){ try{ byte[] byteArray = output.getBytes(); DataOutputStream dataOutputStream = new DataOutputStream(System.out); dataOutputStream.write(byteArray); dataOutputStream.flush(); } catch (IOException e) { logger.info("Exception while writing the output. " + e); } } } The issue is that some messages are lost between the transfer and not all messages reach the AIR client. If I run the java application from the console I am receiving all the messages. It would be great if somebody could point out what I am missing. Following are some of the listeners used to send the event data to the AIR client. // class used to process Shutdown events from the Session private class SessionShutdownListener implements SessionListener{ public void onEvent(Event e) { Session.Shutdown sd = (Session.Shutdown) e; Session.ShutdownReason sr = sd.getReason(); String eventOutput = "eo;" + "Session Shutdown event ocurred reason=" + sr.strValue() + "\n"; ReaderWriter.writeToAir(eventOutput); } } // class used to process OperationSucceeded events from the Session private class SessionOperationSucceededListener implements SessionListener{ public void onEvent(Event e) { Session.OperationSucceeded os = (Session.OperationSucceeded) e; String eventOutput = "eo;" + "Session OperationSucceeded event ocurred" + "\n"; ReaderWriter.writeToAir(eventOutput); } }

  • Which HTTP redirect status code is best for this REST API scenario?

    - by Aseem Kishore
    I'm working on a REST API. The key objects ("nouns") are "items", and each item has a unique ID. E.g. to get info on the item with ID foo: GET http://api.example.com/v1/item/foo New items can be created, but the client doesn't get to pick the ID. Instead, the client sends some info that represents that item. So to create a new item: POST http://api.example.com/v1/item/ hello=world&hokey=pokey With that command, the server checks if we already have an item for the info hello=world&hokey=pokey. So there are two cases here. Case 1: the item doesn't exist; it's created. This case is easy. 201 Created Location: http://api.example.com/v1/item/bar Case 2: the item already exists. Here's where I'm struggling... not sure what's the best redirect code to use. 301 Moved Permanently? 302 Found? 303 See Other? 307 Temporary Redirect? Location: http://api.example.com/v1/item/foo I've studied the Wikipedia descriptions and RFC 2616, and none of these seem to be perfect. Here are the specific characteristics I'm looking for in this case: The redirect is permanent, as the ID will never change. So for efficiency, the client can and should make all future requests to the ID endpoint directly. This suggests 301, as the other three are meant to be temporary. The redirect should use GET, even though this request is POST. This suggests 303, as all others are technically supposed to re-use the POST method. In practice, browsers will use GET for 301 and 302, but this is a REST API, not a website meant to be used by regular users in browsers. It should be broadly usable and easy to play with. Specifically, 303 is HTTP/1.1 whereas 301 and 302 are HTTP/1.0. I'm not sure how much of an issue this is. At this point, I'm leaning towards 303 just to be semantically correct (use GET, don't re-POST) and just suck it up on the "temporary" part. But I'm not sure if 302 would be better since in practice it's been the same behavior as 303, but without requiring HTTP/1.1. But if I go down that line, I wonder if 301 is even better for the same reason plus the "permanent" part. Thoughts appreciated!

  • Ordered delivery with NetNamedPipeBinding using oneWay calls

    - by Aseem Bansal
    Is it possible to guarantee ordered delivery with oneWay calls using namedPipe binding? I have a WCF service/client communicating using namedPipe binding. The client is exposing a callback contract in which all the methods in the callback are marked as OneWay. Something like this [ServiceContract(CallbackContract = typeof(IMyServiceCallback))] public interface IMyService { [OperationContract] void MyOperation(); } public interface IMyServiceCallback { [OperationContract(IsOneWay=true)] void MyCallback1(); [OperationContract(IsOneWay=true)] void MyCallback2(); } At the server side, the implementation of MyOperation method always calls MyCallback1 first and then MyCallback2 but I am observing that sometimes the client receives the calls in the incorrect order (MyCallback2 first and then MyCallback1). On searching the internet I found that the order is not guaranteed with oneway operation as mentioned here and also there is something called reliableSession which ensure message ordering. All the examples on the internet for reliable session are with TCP binding (and not a single one with NamedPipeBinding) and the tcpBinding also has a property called ReliableSession which is not present on the NetNamedPipeBinding. So I am not sure whether reliable session is expected to work with NetNamedPipeBinding or not. Question: Does reliable session work with namedPipeBinding? If yes, how? If no, Is there any other approach with which I can guarantee ordered delivery?

  • sql server optional parameters: syntax for between clause

    - by Aseem Gautam
    @FromDate datetime = null @ToDate datetime = null SELECT * FROM TABLE WHERE .... AND [PI].Date BETWEEN @FromDate AND @ToDate When any date is null, the records are not displayed. What is the correct syntax so that I can get all records if any of the dates are null. I have thought of this: @FromDate datetime = '01/01/1901', @ToDate datetime = '12/31/9999' Thanks.

  • Wordpress like dynamic permalinks in ASP.NET MVC2/3 or ASP.NET 4.0

    - by Aseem Gautam
    Scenario: There are two entities say 'Books' and 'Book Reviews'. There can be multiple books and each book can have multiple reviews. Each review and book should have a separate permalink. Books and Reviews can be added by users using separate input forms. As soon as any book/review is added it should be accessible by its permalink. Anyone can point me in the right direction on how should this be implemented?

  • Flushing stdin after every input - which approach is not buggy?

    - by Aseem Bansal
    While using scanf() in C there is always the problem of extra input lying in the input buffer. So I was looking for a function that I call after every scanf call to remedy this problem. I used this, this, this and this to get these answers //First approach scanf("%*[^\n]\n"); //2ndapproach scanf("%*[^\n]%*c"); //3rd approach int c; while((c = getchar()) != '\n' && c != EOF) /* discard */ ; All three are working as far as I could find by hit-and-trial and going by the references. But before using any of these in all of my codes I wanted to know whether any of these have any bugs?
