Re: [nox-dev] dropping packets
Hi Ricardo and ikf, Thanks for the refresh. I think ikf was trying to install the flow entry and it is not matching for some reason. But the refresh is definitely useful. Btw, I am replying just to correct a typo. You should return STOP to drop the packets, not CONTINUE. And do check nox.xml or nox.json in src/etc to ensure the order of the component being called by Packet_in_event. It is always cool to see the community chipping in. Allow me to say thanks to everyone that have done so, and hope others will help out too. THANKS. Regards KK On 12 July 2010 08:37, Ricardo Bennesby wrote: > Hello ikf.

Re: [nox-dev] dropping packets
Hi Iain, Would you might looking at the control traffic dump to let us know if you keeping receiving more packet-in after inserting the flow rule? Also, is there any reason not to set the vlan_pcp?

If this a repost or it is already resolved problem, I am sorry and please
direct me to old post or the solution.Thanks
I have created a Simple Service as shown below.
package com.tt.ss;

Re: [nox-dev] Issues with multiple OF instances on HP switch
Hi Tim, Depending on which version of NOX you are using, the easiest solution differs. There is the HP firmware Rob mentioned, or I think I might have a patch for NOX-destiny branch (which is pre-pre-alpha) to support 64-bit datapath id. Unfortunately, the patch will not work in earlier versions of NOX.

Re: [nox-dev] lavi integration with NOX
Hi Wenjie, I assume you are talking about the binary formatted LAVI in the openroads branch. Here's a quick run-through of what I see need to be done (probably not at the level of a tutorial): * The LAVI components depends on some changes in the libraries in NOX, e.g. direct OpenFlow messages in a custom event. This should be in the latest version of NOX, but there will be a few more of these. * We will need some custom stuff like flowdb to show flows. Topology is hacked to expose a list of switches too. * Else, the rest should be copying over the files in the LAVI component and compiling. For the rest, the LAVI files are commented using doxygen style comments. You can just run doxygen over the tree and read those. The Makefile has not changed very much in my impression. Maybe you want to clarify what you mean by they look different. Hope this at least clarifies something for you. Regards KK PS>> The destiny branch of NOX now hosts a JSON-based LAVI, which exposes topology. I am considering if we want to support flows out of the repo.

New Formulation for OxyContin FDA Patient Safety News: Show #99, June 2010 FDA has approved a new formulation of the controlled-release drug OxyContin that is designed to be more difficult to manipulate by someone trying to misuse or abuse the medication. OxyContin tablets contain the opioid analgesic oxycodone, which is released gradually after the tablet is swallowed. People intent on abusing the drug have been able to release more of the medication all at once by crushing or chewing the tablets, or by dissolving them and injecting the liquid. The new formulation makes it more difficult for people to defeat the controlled-release properties of the drug by cutting or crushing the tablets. And if someone tries to dissolve the tablets, the result will be a gummy substance that would be difficult to inject through a syringe. Although the new formulation may not prevent all abuse of OxyContin, it is a step in the right direction. The manufacturer will conduct a study to evaluate how well the new formulation reduces abuse and misuse of the drug. Additional Information: FDA Press Release. FDA Approves New Formulation for OxyContin. April 5, 2010. http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm207480.htm FDA Patient Safety News is available at www.fda.gov/psn

[android-developers] Re: GLSurfaceView onPause blocked in Froyo
I am calling it because the documentation tells so. public void onPause () Since: API Level 3 Inform the view that the activity is paused. The owner of this view must call this method when the activity is paused. Calling this method will pause the rendering thread. Must not be called before a renderer has been set.

[android-developers] GLSurfaceView onPause blocked in Froyo
I am using OpenGL to do some rendering and whenever my rendering gets paused I call onPause of GLSurfaceView and later when I resume onResume of GLSurfaceView. This was working fine till I upgraded my Nexus One to Froyo today. After that the thread calling onPause seems to be blocked in that API. Anyone has any idea why this is happening?

[android-developers] How to set and get thread priority from Java and native layers
I have a multithreaded streaming app which has mainly the following 5 threads 1 Main App(UI) Thread 1 controller thread (in native) 1 audio decoder thread (in native) 1 video decoder thread(in native) 1 thread to query the head position of audio (in Java) Apart from this I have video rendering with OpenGL. My problem is, if I query the thread priority using the Thread.getPriority method (my native threads make callbacks to Java and I am making the query at that point of time), I am getting the priority of each of them as 5. For my audio query thread (the last one in the list) I am explicitly setting the priority using Process.setThreadPriority(Process.THREAD_PRIORITY_URGENT_AUDIO); Also for my decoder threads, I am giving higher priority than my controller thread(using pthread APIs in native).

Re: [nox-dev] [openflow-dev] ENVI test
Hi all, Let me clarify this a little (I hope). A few things to note: ** Yuba has two type of git access, SSH and gitosis. Think of them as private and public access respectively. And I apologize for the loose instructions on the website. For all public repository, check out http://yuba.stanford.edu/git/gitweb.cgi PS for this point>> For the uninitiated, you access git via SSH using commands like git clone yuba: and via gitosis using git clone git://yuba/ Yes, I am simplifying but this will be the case for most. ** There are different versions of NOX out there. On top of it, the respective demonstration have their own NOX repositories. There are using corresponding ENVI repositories, since ENVI is customized for each demo. So, we have a lot of repositories. Do not expect the aggregation gui to work with openpipes' NOX repository. ** There is a master ENVI branch at openflowswitch.org and a master NOX repository at http://noxrepo.org/nox. I would recommend everyone starts there unless you are trying to use an existing demo. Caveat: the NOX master branch does not support LAVI now, so it will *not* communicate with ENVI. Hope I have helped to clarify things up a little.

[android-developers] Wifi drop Issues on Motorola Droid
I am trying to develop a streaming application and I am testing it on multiple devices. But I am seeing some problems on Motorola Droid with regards to wifi connection. The wifi connection drops occasionally and comes back in 30 seconds to 1 minute on the Droid. Sometimes while in the middle of streaming I get network connection errors even though I am standing very next to the wifi router. I am not finding this problem with any other devices. Has anyone found any similar issues with the Droid? Any idea what can be done in my program to fix this?

[ts] Filtering Search Results Further
Hello Everyone, This should be a very simple question. Right now, when somebody submits a search, this url is created and the searching works properly http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go! Now that's good but I would like to also sort the results by price. Currently in my view, I have Filter by: <%= link_to_unless_current "Recent", :filter => 'recent' %> | <%= link_to_unless_current "Lowest Price", :filter => 'lowest_price' %> | <%= link_to_unless_current "Highest Price", :filter => 'highest_price' %> The goal was for these links to attach a filter param to the end of the search string so that it looks like http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go!&filter=lowest_price >From there my controller reads in the filter and uses the proper named_scope and returns a new @junks variable that is sorted by price. I know that it works if the filter param is added onto the search query. I just can't figure out how to put it there without typing it manually. If I click any of those links the url goes to http://localhost:3000/junks?filter=lowest_price which brings up non-searched results. Is there an easier way to accomplish what I am trying to do? (I am still a bit green and learning all that I can.) Thanks in advance! -- You received this message because you are subscribed to the Google Groups "Thinking Sphinx" group.

How to do faceting on data indexed by Nutch
Hi All, I might be repeating this question asked by someone else but googling didn't help tracking any such mail responses. I'm pretty much aware of Solr/Lucene and its basic architecture. I've done hit highlighting in Lucene, has idea on faceting support by Solr but never tried it actually. I wanted to implement faceting on Nutch's indexed data. I already have some MBs of data already indexed by Nutch. I just want to implement faceting on those . Can someone give me pointers on how to proceed further in this regard. Or is it the case that I've to query using Solr interface and redirect all the queries to the index already created by Nutch. What is the best possible way, simplest way for achieving the same. Please help in this regard. Thanks, KK.

Re: Transferring an image over an PRC call
Hello,
Thank you for your response. I am a step closer.
Since I am using two servlets (for upload and download) of the image.
do I need to make any changes in .gwt.xml or web.xml file?
thanks

Image upload / store database
Hi, Currently I cannot get the FileUpload widget to work correctly. I am trying to send and receive an image file from the server to the client side. In order to store an image uploaded by a user in my database. I can do this very easy with Java, but when using GWT it doesn't work the same. I'm just not sure how to get this to work, just tried passing the filename using RPC calls but this didn't work. Any suggestions/example will be very very helpful? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

[android-developers] Getting the amount of Audio data buffered in the device
I am trying to write a streaming application. I have my own decoder and I am playing PCM audio using AudioTrack. At any point in time I want to know how much data is buffered with the device. I want to use this so that if the data with the device go below a level, I want to go into a buffering mode where I will buffer 2-3 seconds of data before continuing playback again. Can someone please tell me how to do this? Thanks in advance KK -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [nox-dev] A question regarding Authenticator module
I would like to put forth a "concise rant" here. The short story is that *no one should use flow-in event* and we should deprecate it. I have several reasons for saying so. 1) The flow-in semantics is hard to reason about. We generate a flow-in using packet-in. And if a route cannot be found, the flow-in is flooded? The flooding is actually done to a packet and not a flow. 2) You do not have control over the packet in thereafter. Some two components can be handling the packet-in and flow-in, which refers to the same packets actually. 3) Flow-in really does not give you much anyway. If you want the header fields in flow-in, just use flow.hh. It parses those. So, ends my quibble about flow-in.

Re: [nox-dev] Building nox with older versions of openflow
Hi Tim, In git://noxrepo.org/nox, there is a openflow-0.9 branch. It works with OpenFlow v0.9. I believe routing will not work though, since the flow_mod is not updated. My apologies, I should have backported these from the openflow-1.0 branch. FYI.

And switches these days do not have a lot of buffer or CPU capability (no, we are not always talking about software switches). So, later might not always an option, esp. if the net request rate is greater than the net processing capability. Dropping reduce the net request rate and not delaying. If you like a demonstration of killing a hardware switch with flow stats, grab oflops and run a test. Hope I am being clearer now.

Re: [nox-dev] Questions about NOX event delivery details
I might be wrong, but from my understanding there is nothing in OpenFlow that dictates reliable execution of commands received. I would also prefer an error, but which one would your switch send for being too busy? This is the 6 I know of. OFPET_HELLO_FAILED, /* Hello protocol failed. */ OFPET_BAD_REQUEST, /* Request was not understood. */ OFPET_BAD_ACTION, /* Error in action description. */ OFPET_FLOW_MOD_FAILED, /* Problem modifying flow entry. */ OFPET_PORT_MOD_FAILED, /* Port mod request failed. */ OFPET_QUEUE_OP_FAILED /* Queue operation failed. */ and bad request has the following subtype OFPBRC_BAD_VERSION, /* ofp_header.version not supported. */ OFPBRC_BAD_TYPE,/* ofp_header.type not supported. */ OFPBRC_BAD_STAT,/* ofp_stats_request.type not supported. */ OFPBRC_BAD_VENDOR, /* Vendor not supported (in ofp_vendor_header * or ofp_stats_request or ofp_stats_reply). */ OFPBRC_BAD_SUBTYPE, /* Vendor subtype not supported. */ OFPBRC_EPERM, /* Permissions error. */ OFPBRC_BAD_LEN, /* Wrong request length for type. */ OFPBRC_BUFFER_EMPTY,/* Specified buffer has already been used. */ OFPBRC_BUFFER_UNKNOWN /* Specified buffer does not exist. */ Regards KK On 8 March 2010 21:27, Ben Pfaff wrote: > On Mon, Mar 08, 2010 at 09:23:19PM -0800, kk yap wrote: >> > 4) Do stats request messages time out?

The C/C++ components see the xid since Ofp_msg_event has buf object
that contains all the bytes of the packet. Feel free to parse xid and
export this to Python via swig. Patches are gladly accepted.

Each stats request should be treated independently. As it stands,
OpenFlow does not ensure order of execution, i.e., req2 can be
processed after req1. If you want to ensure order, use the barrier
request. Not sure what switches you are using, but do check that
barrier is supported.
> 4) Do stats request messages time out? If so is there a way to be
> notified of the time out?
Not that I know of. In OpenFlow, it is perfectly valid for a switch
to decide that it cannot handle the stat request and discard it. You
can't really know without sending a barrier request again. Finger
crossed on it being supported in your platform, again.

Hi Guanyao, NOX periodic checks if the switch is still alive by sending an echo request. Basically, your switch did not reply. You should look at the tcpdump to see if you can find the echo reply. If yes, bug people in this list. If no, debug your switch. Regards KK On 1 March 2010 21:34, Guanyao Huang wrote: > Hi > Sorry to bother others. > In my program the datapath leaves network again.

Re: [nox-dev] A quick question about topology module
Hi Guanyao, Can you elaborate? struct DpInfo is paired with a datapathid using a hash_map and contained the destination datapathid using another hash_map. Finally that points to LinkSet that is a lis to src and dst ports. That information is preserved from what I can see.

Re: [nox-dev] Routing with NOX0.6
Hi Martin, I am probably not fully appreciating the problem at hand too. My personal experience is that installing flow entries in the reverse direction (destination to source) and checking if a port is internal before updating host location goes a long time against such race conditions. To some extent, hop-by-hop routing simply slows down the entire process to remove the race conditions. I do not have a good feel of how often this is the case of other deployments, but hop-by-hop routing does not seems like a good default for NOX to be in unless majority of the users needs it that way, which I would contend not.

Re: [sapiensinfotec] Gmodules.com: pra q serve?
Bom dia! Agradeço todas as opinioes, Milton, e q suscitaram algumas outras duvidas... 1. Nao uso IE por gosto, mas nao se encontra outra opçao! Esse suporte telefonico, é em portugues ai no BR...? Eu nao acredito em nada gratuito aqui onde vivo (EUA) ja q em geral sao estagiarios, ou tercerizados na India, Filipinas, ou mais alem. Invariavelmente se tem q pedir pra passar pra o 2o. escalao e as vezes nem ele dá resultados concretos, e se vao os minutos e a paciencia, ate chegar a um impasse qquer.. E prometem um email com soluçoes q acabam numa carta padrao qquer...! 2.O FF fica mito pesado se colocarmos alguns add-ons, ao menos os q ajudam na segurança. O Chrome pra mim é suspeitissimo, e ja nao sou tao fã do q o google faz, agora q estou enfrentando esse caso c/ o gmodules... Safari ainda nao tentei, é verdade, mas acaba-se perdendo tanto tempo em tentativas q nao nos levam a canto algum, q desanima.. Acho q vou instalar e testar logo mais, so q li na web sobre essa mesma reclamaçao, de q o tal gmodules gera paginas vazias tbm no Safari...! 3.Eu vivo no controle de tudo q se modifica tipo Avast, IE, e q tais, pelo Task Manager, ou percebendo o trafego no par de monitores q fica piscando na system tray. Mas é tudo tao rapido q nao dá pra associar todos os movimentos e tirar conclusoes corretas. 4. O provedor... Esse realmente pode ser o inimigo oculto, e sempre tirei qquer programa dos q sao oferecidos na hora em q se assina o serviço. So q to notando e ja tem algum tempo, tipo um mes ou dois, q a cada vez q eu seleciono algum texto, ou adiciono um favorito, isso gera um trafego pois as duas luzes piscam ali no parzinho de monitores da system tray, e dai q ja ando bem sismada com isso... So q por mais q ande a cata de algo suspeito no pc, nao aparece nada extra... Rodo tudo q é cata-fantasma mas nem sombra nem abobora, r... Finalmente, como tenho VoIP e uso uma ATA Grandstream 520, dela vindo o acesso a net pro meu pc, acabo pensando q isso possa ser um outro risco q eu nao devia estar correndo, pois é mais uma brecha q eu nao tenho controle, nao é mesmo...? Bem, voltando ao começo... Alguem q use gmail e outros produtos google, poderia travar o gmodules.com pra ver q q acontece... Eu vou tirar a trava aqui e ver q mais q percebo, e é assim q eu vou engordando a lista do q nao presta pra mim, ali no browser. Pelo q andei fuçando/lendo na web, ja nao é de hoje q esse tal gmodules incomoda, ao menos a uns mais observadores. www.google.com/safebrowsing/diagnostic?site=gmodules.com Sao coisas desse tipo q eu sei q nao adianta perguntar a suporte algum, ja q é claro q existe um interesse maior em manter os misterios, e com tal situaçao se mantem os empregos, e melhor pra o pessoal nao se meter em assuntos q o patrao decidiu q sao essenciais e corretos, e pronto! Vamos ver onde se chega... Boa semana nova, e feliz ano novo nao so chines (agora q acabou o carnaval...) :-) On 2/21/10, Milton Chicoli wrote: > > 1.

Re: [nox-dev] namespace vigil ?
As long as people do not use vigil as a variable. I believe there is more useful things to do with NOX than change the namespace. Are we putting the cart before the horse here?

Re: [nox-dev] namespace vigil ?
Assuming there is enough code not pushed upstream into NOX out there, I am personally against name changes like this. The last time someone changed secchan to ofprotocol in OpenFlow, too much work results. Unless someone volunteer to update everyone's code to the new namespace, I see no reason why such a change should be made.

[sapiensinfotec] Gmodules.com: pra q serve?
ooi.. Será q alguem mata essa charada, se é q chega a ser uma...? :-) Eu achei muitos redirecionamentos ao navegar com o IE7, dai q bloqueei o *. gmodules.com na aba dos sites restritos, ali nas Opcoes de Internet, indo nas Ferramentas. Acontece q o browser agora está uma carroça, e nao vejo um porq disso, mas é quase certo q seja essa a razao pra rolar essa tal leseira. ...afinal quem sao eles e pra q servem...?? A proposito: nao uso o IGoogle, e nem a versao mais recente do gmail... Respostas se possivel com copia pro meu email, ja q estou em modo web em varias listas, por gentileza... Super grata, e bom fim de domingo! KK
[android-developers] JetPlayer keeps logging "write blocked for X msecs" - is this normal?
Hello all, I'm trying to add audio to my game and following the jetboy tutorial and dev pages I'm doing it as follows: I'm initialising like this: JetPlayer JET_PLAYER = JetPlayer.getJetPlayer(); JET_PLAYER.clearQueue(); JET_PLAYER.loadJetFile(p_resources.openRawResourceFd(R.raw.ingame1)); byte sSegmentID = 0; JET_PLAYER.queueJetSegment(0, -1, 0, 0, 0, sSegmentID); then doing: JET_PLAYER.play(); ingame1.jet only contains 1 segment, which is the track I'm trying to play. The audio plays ok but I keep getting these in logcat: W/AudioFlinger( 31): write blocked for 49 msecs W/AudioFlinger( 31): write blocked for 50 msecs W/AudioFlinger( 31): write blocked for 54 msecs They are quite frequent...3-4 of those per second. Is this normal or am I doing something wrong? cheers, kk. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] can an updated version of an app try to restore using a bundle containing older data?
Hello all, I'm trying to prevent the situation where an updated version of my app restores using a bundle written from a previous version of my app. In other words: 1) app v1 stops and calls onSaveInstanceState 2) app v1 saves the bundle (call it v1 data) 3) user goes to marketplace and updates the app to v2 4) user starts the v2 version of the app 5) v2 version calls onCreate passing the bundle with v1 data (i.e. the one saved during step (2)) Is that even possible? Do I need to worry about it? cheers, kk. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
