Lot of Tariff from mDNS

Hi,
We are seeing lot of tariff from mDNS which is coming from printers.
I just like to know why this is happening and why is the mDNS is install on printer.
Do we need mDNS turned on, on printers or it can be turned off.
Please help.

mDNS (multicast domain name service) is also known as BonJour. Because it is a multicast service, it is very "chatty" on the network.
It is basically a peer-to-peer name resolution solution, used where you don't have traditional DNS implemented.
It is often installed for working with Apple Mac (I think older Macs only?)
If you don't have Apple Macs in your network, your could try disabling mDNS on one or two printers, and check for negative impacts.
In our environment, we use all Microsoft printing, with some LPR/LPD printing - and we have no need for mDNS at all (so we have disabled it on all printers)

  • I copied a lot of photos from an iphone to a DVD using a Windows 7 laptop, now I cannot access those photos on the DVD. HELP!

    I copied a lot of photos from an iphone to a DVD using a Windows 7 laptop, now I cannot access those photos on the DVD. HELP! In Windows Exlporer I can see the data on the disk in the details but when I click on it nothing appears as if there is nothing on it.

    It should. So they aren't shown in the Last Import smart album, right? Try the following:
    1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
    2 - Run Option #4, Rebuild Database, followed by Option #1 if needed.

    UPDATE: I had 36 Safari windows open and minimized on the dock from my last session; 20 of those windows failed to open b/c Safari "couldn't find the server"; I just went to the URL bar of all 20 pages and clicked return, and all 20 pages loaded perfectly, without dropping any images or losing formatting. This is a puzzle!!!

  • I loaded a lot of music from my CDs on to my iMac at home.  All my music is stored on the cloud.  So why is the music on my MacBook Pro different.  The CDs are missing from this list.

    I loaded a lot of music from my CDs on to my iMac at home.  All my music is stored on the cloud.  So why is the music on my MacBook Pro different.  The CDs are missing from this list. The iTunes account details I use on both computers is the same.

    Hi Chris,
    Thanks for the reply.
    I think you ave sorted my problem with your question.  I thought that as my iTunes account was on their server (Cloud) and I had previously added CDs which showed up, that all my music was "on the cloud".  I used to use Match but when I turned it off lost all my music that I had previously loaded onto my computer.
    So I guess I have to use the cloud again to access my songs.  This is frustrating as I fly a lot and can not use the music (Cloud based) when the phone is in flight mode as there is no internet.
    So how then do I retrieve all my music to my iMac and have my laptop synced so they are the same?
    I am totally confused now.

  • How can a qm-lot be excluded from availability check?

    Hi experts,
    in oppj I can exclude "stock in quality inspection" from availability check, but the qm lots are still handled as fixed receipts. This is ok, because the qm lots are not a stock. But the availability check shows available quantity and this is, what I don't want!
    The question is: "How can qm-lots be excluded from availability check?"
    Thanks for your help!
    SAP Anwender

    Dear,
    when you talk about QM lot,
    QM lot is created during PO GR or Production order GR. Hence before the GR, MRP showes a recipt is expected and recipt element is either production order or PO.
    Now even after GR, system removes the PO/Production order and increase the stock.
    Hence in availability check if you decativate QM stock, this stock will not be considered, if to be con sidered, then active the QM stock.

  • Lot of noise from laptop audio output

    I'm getting a lot of noise from the audio output of my Macbook Pro (early 2008) OS 10.8.5 when I connect an external firewire 800 drive that uses a power cord. I get more of the same noise when I connect an external video monitor. The noise is a digital hashy and whiney sound that modulates sometimes as what on the screen changes. If I use my Focusrite Scarlett interface the noise is amplified to the point that I can't work. The noise starts when the drive's power cord is plugged in. If I work off a pocket USB drive there is no noise. This is my work around for now. I'm using a power strip that has noise filtering. I have 2 different studios and I get the same noise in both. I've done a lot of trouble shooting and have narrowed the problem down to connecting a drive with a power cord to the computer. I have tried different drives too with the same result. Is there any hope of fixing this?

    Can't say I've ever had any noise when starting the unit up over optical - if your DAC is designed for stereo only then it may be causing noise by attempting to play the 5.1 startup video's audio bitstream which is dolby digital encoded not stereo.

    I wanted to put a capcha, but the site must be on catalyst, and I don't want that, I have my own server. It's a ridiculous limitation yu put there.
    I like tu work on muse, but the fact that I can't use some tools because of choosing not to put my site on catalyst prevends me to use Muse more.
    Anyway, how can I stop the spams ?
    Thanks,

  • Hi. My id country was Saudi Arabia and I bought lots of apps from it. Now I moved to USA and changed my id counrty. the problem now is that every app that I buy in the USA store and I had already bought in the Saudi store won't appear on my purchased list

    Tell me exactly how much you have in your store credit and I"ll let you know the best solution.
    Also, I'm not 100% sure, but when you switch back to S.A., Apple MAY track your IP and still give you probs if they figure you're trying to get around this problem without moving out of America. But we won't know for 100% until we try it.
    If your store change is less than the price of a single song, then you can ask the iTS support to just cash-out that balance. They'll probably send you a response to reverify this first though.
    iTunes Store Support
    http://www.apple.com/emea/support/itunes/contact.html
    Once you change back to S.A. please let us know if you can still see the purchases in the Cloud or not from your US I.P. address as I'm curious if they've fixed this exploit fully or not.

  • Thinking that I was deleting from my iPod, I have inadvertently deleted a lot of music from my iTunes library.  I clicked for retaining on file rather than sending to trash.  How do I get this music back from file into my library?

    Thinking that I was deleting it from my iPod, I have inadvertently deleted a lot of music from my iTunes library.  I clicked for saving to file rather than sending to trash.  How can I get it back into my library?

    See Empty/corrupt iTunes library after upgrade/crash or simply import the media folder back into the library. Restoring a recent backup of the .itl database will restore the original date added values, ratings, play counts, playlist membership, etc. that would otherwise be missing from the reimported media.

    Save the videos to your computer. There must be some way to do it. Read the documentation that came with the app or go to the app online support. Perhaps it uses iOS file Sharing.
    If it is this app, it states in the description that you can transfer the videos to your computer via USB or WiFi.
    https://itunes.apple.com/us/app/tube-downloader-pro-free-video/id586168976?mt=
    I have have an app called Wireless Transfer App. It allows me to send photos and videos to and from the iPad and computer over WiFi.
    https://itunes.apple.com/us/app/wireless-transfer-app-share/id543119010?mt=8
    If that is not the app that I reference above, post back with the exact full name of the app.

  • Forcing program to close, I am deleting a lot of files from my trash but it stopped working about 1/2 way through (1650 files left) so I tried to reboot but it won't let me because a the program is still running which I can't close.

    Forcing program to close, I am deleting a lot of files from my trash but it stopped working about 1/2 way through (1650 files left) so I tried to reboot but it won't let me because a the program is still running which I can't close (stuck at 1650 files to go). So it allowed me to click cancel now it says "stopping" for 3hrs now. Is there anyway to force the MacBook Air (new model) to close as you can't remove the battery?

    Press and hold the power button until the Mac turns itself off. This force-shutdown should be done only after you've exhausted other options (you seem to have done so).
    Wait at least 60 seconds.
    Then press the power button to start up the Mac. It will take a little longer to start up because it will perform additional self-tests on the first boot after a forced shutdown.
    Once the bootup is complete, you should be able to delete the trash. Hold down the option key while choosing to empty the trash, which will automatically delete "locked" items.

    If you purchased Lion for your iMac, just log into the Mac App Store from your MacBook using the Apple ID under which you purchased Lion and go to the Purchases page. You will be able to download and install Lion there. 
    searching the internet i found a link to upgrtade to 10.7
    The only place you get get Lion is from the Mac App Store. If you found some other site, that was an illegal copy and almost certainly tied to someone else's Apple ID and hence unusable by you. If the link was just to the Mac App Store, see above.
    As to the problem with synchronization to iCloud, that's not a 10.6 question, so I'd suggest you take up that specific issue in either the Lion or iCloud forums, providing full details, and someone there can probably help you sort things out.
