Multicast transmission problem

Hi,
I'm tring to multicast audio streams from 1 computer to another on the same network. The multicast address for my network is 10.255.255.255. When I check the amount of transmission bytes from ifconfig continually, I see a gradual increase of bytes being sent out to the network.
When I look at ifconfig on the receiving computer, it is receiving bytes as well. But AVReceive2 can't detect the rtp stream. It just keeps on waiting for the data to come. By the way, I use AVTransmit2 to transmit the data. But when I just unicast the rtp stream from one computer to another, then the rtp streaming works!!
Anyone has the same problem as me. Can anyone point out any problems that I may be having. Oh yeah and I am running JMF between two red hat linux 9 notebooks.
Do I have to do some extra modification to some ip routing table somewhere or sonething?
Thanks to anybody that can PLEASE help me!!!1

Hi Stefan,
If I unicast an audio file from one computer to the other then it works fine. I didn't try sending a video file but I think it should work the same as well. I've got two computers, one having an ip address of 10.0.0.1 and the other having an ip address of 10.0.0.2. Doing an ifconfig, my broadcast address on each computer is stated as 10.255.255.255. When I use 10.255.255.255 to send my audio file, using ifconfig again, I notice that the receiving computer is receving bytes but the program isn't recognising the rtp stream. My program uses a similar address resolution to avtransmit2 and avreceive2.
So I can't figure out what's wrong with the code. Ok for avreceive2, what do you usually type in the command line to receive broadcast packets? Do we have to modify the /etc/hosts file again??
Thanks

As we have written you can get it to work. Just do one of the
following.
1. Make the model a complete mesh. no parts just stuck into
others. Make sure vertecies are welded together properly etc.
2. a) Separate the head,hat,hands etc b) group them together
c) export (the exporter will combine them into one model again).
3. a) Assign a non transparent texture to your model, b)
select the polygons that needs transparency, c) assign the
transparent texture to those polygons
4. Outsource the importing of models to someone else.
I used method 2 as I mentioned in an earlier post and got it
to work, here is the result.

Airport multicast performance problems in u-verse IPTV bridge.

I have a bunch of airport hardware, two n expresses, a draft n extreme, and a 5th generation extreme. I've recently moved to a new house and have AT&T's u-verse multicast IPTV installed. I want to put my TV somewhere without wiring and was going to just do it using a dedicated 802.11n bridge formed from either the two expresses, or the draft n extreme (at the multicast source side) and an express as a receiver.
This seems to work from a functionality perspective, I get the multicast stream into the AT&T set-top box and can watch all of the channels for extended periods of time. The problem that I run into is that I have performance problems that result in the video stuttering, pixelating, and freezing for seconds to minutes at a time. I don't understand why this is the case. The HD stream is less than 9Mbps which should be easily handled by a 5Ghz, n-only link. The source and destination expresses are within 5 feet of each other with clear line-of-sight.
Does anyone have any experience with multicast streaming on aiport hardware? Is there some limitation in the airport implementation where multicast (UDP) packets trigger some sort of slowpath packet processing, so that packets are being dropped? Is there some reporting feature within airport utility that where I can look for diagnostics related to dropped or (extremely) delayed packets? Is there something about AT&T's use of multicast IPTV that is just incompatible with airport hardware?
Note that the u-verse gateway handles all of the IGMP in this situation, and that nothing else is on the network. Well, the 5th gen router is on the network and everything else I own is behind it on a different wifi network. The gateway is smart enough to filter out the multicast traffic so that the router doesn't see it.

Found a solution. Switching from Apple's built-in "create a wireless network" and "join a wireless network+allow ethernet clients" to a WDS network with a main and a remote solves all of the problems. It's not a great option because the WDS network forces me to select a fixed, 2.4Ghz channel, but the IPTV stream is only 8-ish Mbps which seems to be doable, even with all of the wireless networks floating around my house. I guess that it could be a bigger problem during peak wifi usage around here, but we'll cross that bridge when it happens.

Multicast address problems

In the start up scripts for my cluster nodes, I set
 weblogic.system.multicastAddress=224.1.1.100, the address setup by my IT
 group.
 When I start the cluster node, I see the following lines in the log:
 Mon May 15 10:16:05 PDT 2000: <System Props>
 weblogic.system.multicastAddress = 224.1.1.100
 . <other stuff>
 Mon May 15 10:16:06 PDT 2000: <WebLogicServer> Using default cluster
 multicast address 237.0.0.1
 Mon May 15 10:16:07 PDT 2000: <WebLogicServer>
 =========================================================
 Mon May 15 10:16:07 PDT 2000: <WebLogicServer> = Joined cluster
 cluster_1 at address 237.0.0.1
 Mon May 15 10:16:07 PDT 2000: <WebLogicServer>
 =========================================================
 Why is weblogic joining the cluster at address 237.0.0.1 when I
 specified 224.1.1.100?
 In terms of the resulting behavior, jsp page requests to the proxy
 server are passed to the single cluster node and a page is generated
 without error. As soon as I add another cluster node to the cluster,
 requests that form a new session never send a response. I suspect that
 the cluster nodes are having trouble replicating the session.
 Any help?
 - Kevin


Thanks, this causes the nodes to join at the desired address.
 I am still seeing, however, that the jsp pages I want work file when
 there is one node in the cluster but hang forever when there are more
 than one nodes. The MulticastTest utility runs successfully. Can you
 suggest any other debugging options?

Parameter transmission problem

Hello! I have the following two classes:
public class VeterinaryReport
int dogs;
int cats;
String name = new String();
public int GetAnimalsNo()
return dogs + cats;
public void DisplayStatistics()
System.out.println("Total number of animals is "+ GetAnimalsNo() + ".");
System.out.println("The owner of the animals is "+ name + ".");
return;
import java.io.Console;
class VeterinaryTest
        public static void SetName(String name)
         Console cons;
      if ((cons = System.console()) == null)
      System.err.println("No console.");
      System.exit(1);
      String login = cons.readLine("Enter name for veterinary: ");
         name = login;
         return;
        public static void main(String[] args)
           VeterinaryReport vr = new VeterinaryReport();
           vr.cats = 20;
           vr.dogs = 40;
           SetName(vr.name);
           vr.DisplayStatistics();
           return;
}, and the problem is no names are displayed at the call of DisplayStatistics, like this: "The owner of the animals is ."
Inside the function, everything works, so I guess it's something of parameter transmission that I don't know about.
can anyone see what goes wrong?
Cheers

The problem is that the SetName method is in the VetTest class and not the VetReport class. There is absolutely no connection between the name variable in the SetName method and the VetReport class. So that means that whatever changes you make to the name variable in SetName has no effect on name in VetReport. When you print out the data name in VetReport is still an empty string and that is what you see on the screen: nothing.

Transmission problem

The transmission torrent client is showing that torrent X is loading with 70KB/s, but the size of downloaded file is the same all the time. when i pause the torrent and start it again it loads about 5MB and stops again. System monitor in gnome and ifconfig show that I am receiving data but it looks like transmission discards that data. Even if it discards that data the details menu for torrent X shows there has been no or few KB of failed download. I tried different torrents from different trackers and different access points but the problem is still there. Can anyone help me?
I am using latest versions of transmission and iwl3945 for my wireless card.

EA2700 Bonjour / Multicast DNS problem

I've just updated from a Linksys E2500 to an EA2700. The new software features are great, however multicast DNS (aka zeroconf / bonjour) service discovery is not working between wired and wireless connections. (Wireless to wireless is fine, just not to wired).
The last time I saw this problem was a crappy Dlink router about 10 years ago, and I have never seen it on a Linksys produce before now (3 previous modems/routers).
I have no issues connecting to the internet, or connect to devices by their IP addresses. The problem is the service discovery, which is used for things such as Airplay video mirroring, Time Machine backups (and file sharing), iTunes music sharing and more.
Has anyone else has any issues with bonjour service discovery from wired to wireless connections on the EA2700? Or, even better, found a solution?

Hi mattconnolly ,
Most of these Linksys Routers use DLNA/UPnP for network discovery. Zeroconf creates a local domain, so devices are discoverable through names like my router.local or canon printer. local instead of its local IP address. This has been implemented on new Linksys Smart Wifi line but only for accessing it's setup page (myrouter. local) - and there were times that it breaks.
You can try to turn off/on your router, but it doesn't really fix/resolves it. You can try also to update your device's firmware. The firmware latest release update is dated 11/19/2012 (1.1.39 Build 145204) and based on the release notes, there's a Fix for Multicast traffic issue on it's release version 1.0.14 (Build 129982). Other than this, you might want to check on a much more flexible operator - WRT1900AC.
Good luck!

Ethernet gem 0 and gem1 transmission problem in dual core

I followed Xapp 1079 article on my custom board.I am able to see output(cpu0 and cpu1 hello world) on putty.
In my custom board two ethernet ports are present.Aim of the project is eth0 port in cpu0 has transfer the data to eth1 port in cpu1.
cpu0 contains the eth0 port which takes the data from pc1 and transfers to eth1 port.cpu1 contains eth1 port which takes data from pc2 and transfers to Eth0 port.
In following conditions communication is happening successfully
1.
In cpu0 drivers intialised for both eth0 and eth1
And written code eth0 to eth1()
eth1 to eth0()
i checked ping b/w pc1 and pc2 communication is happening
2.
In cpu1 drivers intialised for both eth0 and eth1
And written code eth0 to eth1()
eth1 to eth0()
i checked ping b/w pc1 and pc2 communication is happening
If i try to place code of eth0toeth1() in cpu0
eth1toeth0()in cpu1
then ping is not happening between the two pc's.I debugged and checked one function called XEmacPs_BdIsTxUsed().
if transmission bit is 0 always faling .
please give me the solution for this problem

I believe that he intends to recompile everything (not just his kernel).
@OP:
Recompiling your kernel is only worth it if you modify the .config. Rebuilding everything else is pretty much useless (unless you want to add buffer overflow protection etc.).

WES7 UDP Multicast Open problem

Hi
I am using LabVIEW 2012 SP1 programming a TPC-2206 touch-panel computer running Windows Embedded Standard 7.
I have a fairly simple program which uses the LabVIEW "UDP Multicast Open" VI to open a Read-Only multicast port, then reads data continously from it using the "UDP Read" VI.
The routine works by calling the "UDP Multicast Open" VI and if successful, then entering a continous While-loop which reads from the opened port via the opened Connection-ID refnum. If unsuccessful at opening, the routine sits there waiting for the Open to succeed, displaying a message to the user that the network is not plugged in (or similar).
My problem is that if I open the port without a network connection, the open operation succeeds (which is great as its a multicast open and that seems like the right thing it should do), but subsequently when I plug in the network with good data being sent on it, I do not receive anything?! I would have expected data to be received if the port succeeded in opening, no matter what the initial condition of the connection.
When I tried this on Windows XP, I got a open failure which let me know the network was not plugged in. I subsequently programmed it to put up the flashing message and waited for a good connection such that "UDP Multicast Open" then succeeded. Subsequent reception was then good.
Is this a known difference between WES7 and WinXP and LabVIEW "UDP Multicast Open"/"UDP Read", or am I missing something?
Thanks for any help you can give.

Thanks for the reply. I have also checked that example. Please note that in the example it doesn't have an input for the net address, which i assume labview 2011 will use 0.
I have also just received a reply from NI and confirmed it's a known bug in 2011. i will post it below.
I hope this finds you doing well. I am glad to hear that you are starting to upgrade to 2011 and I apologize for the issues you are seeing. I suspect you are using this on one of our Real-Time targets if so the good news is that this behavior has been documented in the form of a CAR (actually a
few): Broadcasts and the UDP Open VI have an INCONSISTANT behavior depending on the OS. Pharlap/Windows receive broadcasts when the "net address" terminal is wired while vxWorks/Linux don't. These CARs are scheduled as major incoviencience and will be fixed in a future version of LabVIEW as of now the work around is to simple not wire the net address field.
The CAR numbers incase you would like to see when they are fixed are:

Multicasting data problem

Hi.I am trying to multicast a long number over three clients,but when I check the number I receive, is sometimes a combination of two numbers that clients sent.For example,client 1 sends 12345(which I can read from other two clients) then client 2 sends 234567(which I can read also)after that client 3 sends 789. When I check the number received by client 1 and 2, I see that the number is 789567(combination of numbers send by client 2 and 3).I am clearing the byte arrays in datagrampacket after I send or receive.I still could not figure out how client 2 could send while client 3 is sending.Does anyone have and idea what could be the problem with that?Thanks.

Multicast stream problem with windows media service

Hi,
I'm on a simple LAN composed by cisco 3560G and 3750G switches. On one of my switches, i've connected a windows media server that stream tv in unicast and multicast mode.
When i run the http://myserver/mystream.nsc generated by the server on the current server, it's working, i can see my stream. The problem is in the stations, i'm unable to see it.
I've activated IGMP Snooping on each switchs.
Here is the log of debug ip igmp snooping on the switch where the server is connected :

As WMP is not a DVD player, my suggestion would be to tell your clients to never use WMP.All our DVD discs go out with a warning not to allow WMP to be used.
In most computer setups, WMP does not play back video correctly as it does not have an MPEG codec installed, or has navigational problems.
All computers that have a DVD drive fitted, will have a dedicated DVD software player installed, such as Win DVD or Power DVD, so why not use that?

Airserver multicast mDNS problem

I have WLC 2504 running 7.4.100.0 with a single 1242AG AP
single wireless SSID on the WLC
an Apple AIRSERVER and an IPAD which should be able to do mirroring to show ipad screen on the pc
they have IPs in same subnet and have base connectivity
it just wont work! the ipad never sees the airplay server option come up
BUT
if i move these 2 systems to a cisco autonomous AP. or another commodity wireless LAN and have the 2 systems (pc/ipad) in same subnet it works
if i have the pc on wired and the ipad (wireless obviously) this work on the autonomous or commodity AP fine
so there is something "different" about using the WLC/LWAP right?
i have tried with and without the various multicast options enabled etc
please can anyone advise or help?
many thanks
dave

thank you both for helping me and for the pointers.
I have a config (attached)
I have this update to the case:-
laptop and iphone on same wireless LAN (interface3) wireless LANcalled clients34
With the command
config mdns snooping DISable
i can see the Airserver from the iPAD and it works (WITHIN) the wireless WLAN i.e. both on same WLAN and IP subnet
if i issue
config mdns snooping ENable
the
Airserver disappears and wont work
it comes back as soon as i disable the mdns snooping
this is consistently reproducible
any ideas welcomed
it never works between WLANs (so far!)

NAT7210 to host data transmission problem

Hello!
Years ago, our company developed a GPIB interface board, using a NAT7210 GPIB controller which is hosted by an Atmel 8 bit MCU. For a test, the board is connected to a NI GPIB PCI interface, using MAX and NI-488 Communicator for communication.
Everything works fine so far, except one thing: a customer complained about occasionally "distorted" responses to the *IDN? query. We verified this to be true.
The response sometimes contains one additional character. For example, if the response string to the *IDN? query would be 70 bytes (including end token 0xA), sometimes it is 71 bytes and the additional character, which is mostly a ">" (0x3E), is inserted in random position.
Sometimes it's even worse. Then the NAT7210 sends the string twice, making it 139 bytes. This error occurs every few times when querying *IDN?.
The MCU that controls the NAT7210 does not send this additional character. I can verify in the debug mode, that the buffer content that is sent to the GPIB controller is OK and the code is OK, so that sending data is not interfered. We don't have any clue how to stop this. The NAT7210 has no command to flush its output buffer, nor we know if it does automatically after sending the message via GPIB.
Does anybody have any idea what's causing this and how to stop it? TIA

About NAT7210:
The problem with those GPIB controllers is that there are too many "ORs" in the manuals. "Do this OR do that". Too many options when setting up the config of a controller making it almost impossible to find the right one. We strictly adhered the initialisation sequence as told in the manual. But NI or other GPIB controller manufacturers don't mention a word about timing of the control data between host MCU and NAT7210. I also couldn't find example code for best configuration.
However, the chip and the GPIB device are working smooth on the bus, except that one single problem. So I doubt if the controller is set up incorrectly.
I can not ensure that there is no noise on the bus, but I only have that one controller chip as talker/listener on the bus.
The number of queries after the problem occurs again is arbitrary. Sometimes 1, sometimes 5, sometimes 10 queries. The frequency of the double string is not so high as that of the additional character.
About rich text editor:
I'm using Chrome. The behaviour with the missing button strip and mode switching only happens when starting a new topic after searching the forum and pressing the blue button "Post" above the search result window. When replying to a thread, everything is fine, even switching between Rich Text and Preview modes. In the other case, the windows contents were deleted when switching view mode.

WRT54GX VER2 WIRELESS TRANSMISSION PROBLEM

My wireless transmission indicator on the router is not coming on. and the POE is blinking consistently, i have tried to reset the router, but its not granting me access into the router.. it all started when i was upgrading the firmware of my router, there was a power interuption during upgrade

well....as the firmware upgrade was interrupted it seems that the router must have been damaged ....
you can still try resetting the router for a minute .. do a power cycle .. check whether the computer gets an ip add and it is able to ping the router ..

JESD204 Transmission Problem

? signal integrity ?
is there a test mode in the system where you can test the link / BERT between two ?
wonder if the values change with tempature ?
just a thought ,

I'm currently working on setting up a JES204 connection between a Xilinx ZC706 and a DAC FMC card. I have seem to run into a weird situation in my configuration process. I have programmed the JESD core on the FPGA side with the correct values, but my DAC is recieveing some incorrect values for the M, Subclass, and JESDV (jesd version) values. I have experimented some with the M value and found that I recieve the correct value on the DAC if the value is a 0,1,2, or 4. However if I try to use the value I need (a 3) the DAC recieves a 1C. The other problem is the 1s for subclass and JESDV turn into C's.
All the other values work fine, but for some reason these three don't appear to work properly. Would anyone be able to provide some insight?
