Multicast Listener Report Message purpose

Hi everybody.
An ipv6 host performs dad before starts using ipv6 address. For example our router is an ipv6 client performing DAD as shown below:
::     ff02::1:ff00:2222         ICMPv6 78 Neighbor Solicitation for fe80::200:ff:fe00:2222
fe80::200:ff:fe00:2222         ff02::1 ICMPv6 86 Neighbor Advertisement fe80::200:ff:fe00:2222 (ovr) is at 00:00:00:00:22:22
fe80::200:ff:fe00:2222          ff02::16 ICMPv6 90 Multicast Listener Report Message v
What is the purpose of " Multicast listener report message" above ?
The " multicast listener report message" in expanded form shown below:
No.     Time        Source                Destination           Protocol Length Info

Thanks and have a great weekend.

I think the MLD report is to ensure that the MAC address isn't subscribed to any stale multicast group memberships left over from the previous client network configuration.

ICMPv6 'Multicast Listener Report' messages flooding the local network

Hi all,
We have a small number of 93z desktops scattered around our school. There seems to be an issue with the ethernet adapters running the Intel I217 chipset. When these machines are in sleep one or more start sending IPV6 "Multicast Listener Report Message v2" packets to the network (observed by Wireshark). Then they begin to snowball and shortly thereafter they are flooding the network, bringing it to its knees.
We had the same issue on some Dell workstations, however, Dell released a firmware update to address this issue with this chipset.
Just wondering if this is an issue Lenovo is aware of and/or has addressed. We've worked around it on Lenovo's machines by disabling all power options on the ethernet adapters but we shouldn't have to do that. If Dell can provide a firmware fix why can't Lenovo (assuming that they haven't).
I know I'm not the only one - https://www.google.com.au/?complete=0#complete=0&q=intel+I217+flood&safe=active

I can't tell you which drive to use because Lenovo are terrible with drivers, however, the best way to workaround the issue is to disable the power management settings on the adapter...
We had the same problem on some Dell T1700 workstations, Dell moved very quickly to release an updated BIOS and driver that resolved it. Intel, I believe, have also corrected this in their native drivers but I'm unsure (and unwilling to test) if Lenovo have, I don't believe they had as of a month ago as we reimaged some machines and updated them with latest drivers through the update tool and then we started seeing multicast traffic again.
Lenovo support is rubbish.

Why not use application specific multicast listener in appserver cluster

Hello Friends,
I am using oracle9iAs. we have basically two enterprise application. and often they communicate to each other, currently we have message bean sending a message with is nothing more than 2 integer values. The second application uses these two integers to update specific data cache.
First of All I am not aware or have come across any documentation on JMS clustering in Oralce9iAS. they still are very much behind Weblogic interms of feature implementation, If I wrong correct me here.
Now coming to my requirement, we are clustering application servers now and I need to be able to send messages to all
the servers in the cluster, lets say message generated by server 1 and application A to Application B on all other servers in cluster including the host.
well My dilemma is I want to use JMS but How to subscribe to different topics on cluster if topic is not only cluster able,.. if topics themselves running in clustered servers are not clustered.
so the easiest way for me to do this is to use a Multicast Listener on Application B on all the servers in the cluster and send message to it. well I know I will using socket here,... but I do also have control over transaction scope, this message is only sent upon successful completion of transaction on Application A.
now I ask my question. In this situation do things is there any risk that I am taking by using MulticastListner in my app?
your thoughts and ideas are appreciated
Thanks
Jay

Scrap JMS. Use plain java.net or JINI.
You could create a Peer-to-Peer Chain:
Server A -> Server B -> Server C -> Server A
On each Server have a server listening for messages (from the Server to the left in the chain) and a client that sends messages (to the Server to the right in the chain) and an application that links the server and client on each Server.
So,
Server A's "server" listens for messages from the "client" on Server C, and so on.
This is vary efficent. A simple send-receive chain that is clusterd within a small (or large) group of Servers. You could also try Bi-Directional Parallel Communications BDPC. That would basically have Server A send messages to both Servers - one to the left and one to the right, then at the same time, listen for messages from the Server on the left and the Server on the right. This is better suited for large-scale clusters where a Uni-directional communications model would take too long to propogate messages to every member of the group.
But, that's just me.

Itunes wont open/ immediate "send error report message"

So I had a problem with me trying to install itunes 7.3 because of a missing itunes.msi. I followed the instructions i found from this forum as follows
"1. Go to http://www.ccleaner.com/ and download and install CCleaner. Run this program and click Run Cleaner. This program will remove most of your temporary files.
2. Go to http://download.microsoft.com/download/e/9/d/e9d80355-7ab4-45b8-80e8-983a48d5e1b d/msicuu2.exe and download and install Windows Install Clean Up utility. Click on iTunes and click Remove. Do the same for Quicktime.
3. Now you need to manually delete all of your iTunes and Quicktime files. This can take a very long time. Just go to C: and start searching through.
4. Go to the Run box and type in "regedit". Go through all of the folders in there and delete all iTunes and Quicktime files.
5. Go to Add/Remove Programs and Remove iTunes and Quicktime.
6. Download iTunes again and install it."
I then tried to open itunes and immediately a message pops up asking if i want to send an error report to microsoft. It seems as though step 4 might have truly made things worse.
Someone please help
Windows XP

After you get the send error report message go to:
Start -> Control Panel (In classic view which can be enabled by clicking view classic.) -> Administrative Tools -> Event Viewer.
Select the Application log and look for the most recent errors (Marked by a red X).
Double click on the error and it will show you a full description. For an error similar to the one you are recieving it should report a 'faulting module' in the error.
Please paste that here. This will help us help you.

Firefox crashed, now won't start, crash reporter message every time

Greetings,
I was using firefox as usual and all of the sudden it crashes and it's now gone and everytime I try to start up a new browser the same crash reporter message comes on:
"Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts."
I've restarted, created a new profile..nothing works. Cannot access safe mode. Cannot access anything. In fact, when I try to access older bookmarks which I backed up and saved on a flashdrive and want to view them, the same error pops up with the crash report. I'd like to know if my bookmarks (old and recent) can still be accessed and backed up and that I can solve this problem and use firefox again soon.

More details:
The regular/non-extended Hardware Test returned no problems, despite taking hours for what was supposed to be a 3-5 minute test. I haven't dared run the extended.
I also tried removing third-party RAM and using the original configuration, then just the third-party and no Apple, etc.. It's not the RAM, as the problem is exactly the same.
I'm going to call up Apple support when I can, but just looking for other things I can check or possibly do until then, or just insight on what the problem could be.
Is it most likely the graphics card? Could it be an issue with the core hardware?

Itunes get "Send Error Report" message

Alright so when I try and open itunes I get a send error report message. I've tried updating it and that doesnt work and I've already tried reinstalling it. I thought quicktime was the error so I went to try and remove it from my computer. As it was loading to remove quicktime I got a "fatal error" message and quicktime could not be deleted.
Help please?

Itunes has encountered a problem and needs to close
the first thing that i check for when people report getting that message when they try to launch their itunes is a broken QuickTime.
try to open your QuickTime. does it launch properly, or do you get an error message?
if you get an error message, the first thing we'll try is a careful standalone QT 7.1 reinstall.
download and save a copy of the QT 7.1 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
Quicktime 7.1 Standalone Installer
if that install goes through okay, does your itunes launch properly again?
(if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)

Itunes 7 error report message

i recently downloaded the new itunes, and it messed up everything. I ran the install program and when i tried to run the program, i get an error report message. It says that the program cannot open. I have tried unistalling, and redownloading, and nothing works. I also tried to revert to 6.01 version, but that didnt work either.Im running a dell, with os windows xp. any help would be much appreciated.

let's get a crash log to the Apple Engineers for a look.
Typically, you'll need to configure Dr. Watson on your PC in order to generate crash logs. Windows start menu -> Run. Type in "cmd". Hit return. At the prompt in the command line window that comes up, type in
drwtsn32 -i
And hit return.
This will create crash logs in Documents And Settings\All Users\Application Data\Microsoft\Dr Watson\. There'll usually be a file in here called "drwtsn32.log"
prior to collecting the itunes crash log, delete any existing crash logs in there. (we want to make sure we send the correct crash log.)
Generate the crash, collect the crash log, and send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing (if you are seeing one)

ITunes "Send Error Report" Message/Quicktime Problem

This is a problem that has only occured after I updated my iTunes to 7.0.2. Some songs in my library, and all of my videos that I have bought through the Music store cause the "Send Error Report" message to come up and iTunes closes down immediately.
I read another thread that a similar problem was occuring to a customer, and one of the admins requested him to un-install Quicktime and delete 2 files out of the registry. Then re-install quicktime through the "Repair" section of the iTunes installer. I followed these steps and the problem seemed to be fixed, but then they were "re-corrupted" I guess after I restarted my computer.
Do you have any idea what would be wrong? I know it is not spyware/viruses because I have several programs to check/delete them.
Thanks for your help

Bump for the 3rd time.
Quicktime will not even open, on a sidenote. It starts to load, then I hear some sort of beep..then it closes. I have tried re-installing multiple times and the problem continues.

Firefox won't open I get a "Mozilla crash reporter" message instead.

I bought a new computer and downloaded Firefox. I had brought my settings over with Easy Transfer and everything worked a few times. Now when I try to open FF it immediately shuts down and gives me an crash reporter message. It doesn't actually open up it just goes directly to the crash reporter message. I've done that a few times. I uninstalled the program and then did a new download a few times and it's still happening. Please help. I've never gotten a response from m numerous crash messages I've sent in and I've posted on this forum and then can't find it. I feel like I've fallen through the FF black hole. Do I exist??

Interactive report messages - translation

Hello,
I'm trying to translate all of the interactive report messages, on Apex 4.2.
I'm using this [http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35125/global_messages.htm] as a reference.
I have several problems translating the help section of the interactive report.
First of all, I can't seem to find all of the message names. The ones I couldn't find were:
Sets the number of records to display per page.(regarding displaying certain number of rows per page)
Format enable you to customize the display of the report. Format contains the following submenu:
    Sort
    Control Break
    Highlight
    Compute
    Aggregate
    Chart
    Group By(regarding format)
You can define one Group By report per saved report. Once defined, you can switch between the group by and report views using links below the Search bar. To create a Group By report, you select:
    the columns on which to group (up to 3 columns can be selected)
    the columns to aggregate along with the function to be performed (average, sum, count, etc.)
    the columns to use for sorting (up to 3 columns can be selected along with direction and null sorting options)(regarding group by)
And secondly, I have translated this message
    Select columns icon enables you to identify which column to search (or all).
    Text area enables you to enter case insensitive search criteria (wild card characters are implied).
    Go button executes the search.
    Reports displays alternate default and saved private or public reports.
    Actions Menu enables you to customize a report. See the sections that follow.using this message name: APEXIR_HELP_SEARCH_BAR.
However, now I have two messages shown in that section: the original one, in English, and the translated one.
Could someone please help me out?
Thank you!

I only have one video project that I ever published to iDisk. It didn't have any music or photo files attatched to it, just a few clips stitched together. I can play these clips right now in the Event Library (so I know the source files are on my computer), but strangely, under the Project Library, the project is not there. I'm almost certain that I didn't store the project on iDisk; I just completed the video and published it to iDisk (as a .mov file I think) for family to see. I've tried to figure out how to get iDisk to stop looking for this project to no avail.
I don't know if others have experienced this, but if I click on any project and on the menu bar select Share --> Remove From --> Media Browser... it lists iPod, iPhone, iPad, tv, Computer and MobileMe. Why would MobileMe be an option here? This is the case for any video project I select. Didn't iLife '11 and/or OSX 10.8 remove all mention of MobileMe? I wonder if this is part of the problem too.
Edit: I just removed every project I have from the Media Browser. Still no luck.

How do i sync my contacts from my iPhone with my macbook pro for messaging purposes?

How do i sync my contacts from my iPhone with my macbook pro for messaging purposes?

Hey dthompson2108,
Thanks for participating in the Apple Support Communities.
You can sync contacts between your iPhone and MacBook Pro using iCloud or iTunes.
See this link for help with setting up iCloud on your computer and device(s):
Apple - iCloud - Learn how to set up iCloud on all your devices.
Instead of turning on iCloud on your iPhone and Mac, you can sync using iTunes as explained in this article:

Howto bind multicast listener to a specific network interface (NIC)?

All of our cluster machines have 2 network interfaces. One of the requirements is that all cluster-related traffic has to use a specific interface, leaving the other open for all non-clustering network traffic.
Thus, I've to bind the Coherence multicast listener to a specific interface.
Unfortunately I did not find a setting for this in the Coherence configuration XML file.
Is it possible to bind the multicast listener to a specific NIC, if yes, how can it be done?
Thanks a lot!
Best regards,
Wolf

Hi Wolf,
it can be specified as part of the unicast-listener configuration within the operational configuration:
http://coherence.oracle.com/display/COH34UG/unicast-listener
You need to specify the address and the port elements.
Alternatively, you can specify values for this as a Java property:
-Dtangosol.coherence.localhost=nicaddress -Dtangosol.coherence.localport=unicastportwhere nicaddress is the ip address of the network card going to the network you would like to direct Coherence traffic to. Unicast port is the udp port on which Coherence will listen. By default it is 8088 (or automatically incremente in case the port is already bound).
If your kernel is configured to use both ipv6 and ipv4 and you specified the ipv4 address of the network card then you might also need to specify:
-Djava.net.preferIPv4Stack=trueThe multicast listener and publisher will send and receive on the interface used by the unicast listener.
Best regards,
Robert

Multicast listener join-timeout-milliseconds docs are incorrect?

Hi,
I was attempting to make my local development startup faster by doing this in my tangosol-coherence-override.xml file:
<multicast-listener>
<join-timeout-milliseconds>1</join-timeout-milliseconds>
</multicast-listener>
Basically, I want to disable multicast, but since that's not currently possible, setting it to the quickest timeout seems the best way to accomplish that. We use well-known-address lists and don't rely on multicast anyhow.
The docs here: [http://coherence.oracle.com/display/COH35UG/multicast-listener] seem to indicate it should be possible to set the value to 1, but at startup, I get this error:
2010-02-10 17:13:54,511 INFO [C3P0Registry.java:204] Initializing c3p0-0.9.1.2 [built 21-May-2007 15:04:56; debug? true; trace: 10]
2010-02-10 17:13:54.970/41.077 Oracle Coherence GE 3.5.2/463p1 <Error> (thread=main, member=n/a): Error while starting cluster: java.lang.IllegalArgumentException: Value out of range [1000, 1000000]: 1

 at com.tangosol.coherence.component.net.ClusterConfig.fromXml(ClusterConfig.CDB:46)
 at com.tangosol.coherence.component.net.Cluster.configure(Cluster.CDB:10)
(omitted many lines for brevity)
Setting to 1000 works and definitely speeds up startup during development, but setting it to 1 would be even better. Can the docs be updated, or maybe get a feature to disable multicast entirely?
Thanks,
