How many concurrent devices does home sharing on iTunes support?

On my appleTV, if I'm watching something from my home iTunes library through home sharing, then on another device, like my iphone, I access the same shared library through home sharing, the appleTV immediately drops connection and cannot see the shared iTunes library.
This happens across all devices, yet apple specifically mentions the need to use the same appleID across all devices. If I cannot home share to multiple devices at once, how will this EVER work.
Is there something I might have configured wrong? If I enable home sharing on enough devices, you cannot possibly complete a full TV show on the appletv without at least one of them accessing the library and kicking it off.
How would 2 appleTVs ever work at the same time to stream different programs from the itunes library?

Hi Faiz,
There are not any known issues in terms of URLs failing. I would perform a packet capture on the WSA. See my instructions below:
In order to obtain a simultaneous packet capture from the WSA & PC you will need to log into the GUI ->Support and Help -> Packet Capture -> Edit Settings -> Select the radial button No Filter.Please send me a packet capture from the WSA unfiltered. You will need to install wireshark on the PC or laptop you are testing from. It is a good idea to start the wireshark program from the PC first. I would recommend using www.iana.org as a test as it uses only on IP address.
When you have the captures completed I would first look at the WSA packet capture and use the following filter in wireshark http contains "www.iana.org". The various streams of communication will populate in the wireshark display. What you want to focus on is the streams that show the IP of the WSA and the IP of www.iana.org 192.0.32.8. We should see the following when you right mouse click the packet which shows the IP of the WSA going to the destination IP of www.iana.org:
WSA IP -------SYN-----> www.iana.org IP
WSA IP <--SYN/ACK-- www.iana.org IP
WSA IP -------ACK-----> www.iana.org IP
If you see this instead:
WSA IP -------SYN-----> www.iana.org IP
WSA IP -------SYN-----> www.iana.org IP
WSA IP -------SYN-----> www.iana.org IP
WSA IP -------SYN-----> www.iana.org IP
Then you have a problem in your network.

How many OSPF Processes does a Cat6500 w/ Sup720 support?

Hi,
we've to build many vrf's and have to run
OSPF on each of these.
My question is, how many OSPF Processes does a Cat6500 w/ Sup720 can support?
regards
kf

Harold,
Thanks for the clarification. I hope you don't mind one more question. I have looked it up..http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123newft/123t/123t_4/gtospfvf.htm
but it is not clear whether multiple vrfs can share the same routing process through the routing context mechanism. If this is not supported yet, then I wonder how scalable this is, and in particular whether service providers will view this as a viable feature considering the demand on resources on a PE router to run multiple (according to the document, depending on platform, up to 10,000!) ospf processes?

E.

How can I disable Library/Home Sharing in iTunes?

So, i have two apple computers connected to the same network, one iMac connected via ethernet cable, one MBP connected to wifi. There are also other apple products connected to the same network but i don't think they have any relation to the problem that i have.
On both machines i have Home sharing turned off and i have even disabled all the options from the General sharing menu (outside itunes). Despite all this, i can see on both machines the other machine's library and i can play everything, music, videos, playlists, etc. What is even stranger is that in iTunes general preferences i have unchecked 'shared libraries' so i shouldn't see it even if it was shared. I have even tried to activate home sharing but to select nothing in the sharing list...no change. i am not even loged in to itunes or app store. Both macs have 10.8.3 and itunes 11.
What i suspect may be related to this:
Initially i had only the macbookpro with a user id, password, library name 'username's library'. After i've bought the imac i have set it with the same accound name, password and of course library name was the same. At some point i had home sharing on both machines since i used the same apple for it.
Does anyone know how to fix this? I mean normally i wouldn't care but i think that because of this, my imac does not go correctly to sleep, or wakes up when i open itunes on the other machine. I have wake on demand ON and i do not want to turn it off since i keep it on to ssh from the MBP and run some scripts, etc while the iMac is sleeping
Any ideea is welcomed! Thanks!

Welcome to the Apple Community.
You would only need homesharing on your iPad if you want to use the remote app (which is quite handy actually). To be able to use the iPad with the Apple TV, you use AirPlay, but the iPad won't show up in a list on the Apple TV, you send content from the iPad itself.
Assuming both devices are on the same network and that AirPlay is not turned off on the Apple TV, then simply tap on the screen when you are watching content you wish to stream to your Apple TV, then tap the airplay icon that appears in the control bar, choose the Apple TV from the menu that appears.
When displaying the content you wish to mirror on the iPad 2 (or better), iPad Mini, iPhone 4S (or better), double tap the home button (quickly) and swipe the bottom row of apps to the right to reveal the playback controls, tap the AirPlay icon and select your Apple TV from the list of available devices.

How many concurrent connections does WSA S670 appliance support.

Hi All,
Good Day!
We have an issue with our Ironport WSA S670 appliance. We have around 35K users and have access to sites like facebook.com, youtube.com etc.
The issues is that at times certain sites are not accessible via proxy. For example we cannot access youtube.com, google.com etc while we can access msn.com, espn.com etc. Moreover when we try to bypass the proxy and access the sites directly all the sites works just fine.
This issue has been repeating many times and we checked the internet link, proxy etc for any issue. In the meantime the issue gets resolved mysteriously.
The total number of connections at these times are more than 20K. The CPU utilization never goes beyond 15% but the memory is always between 70 to 90% utilized.
What is the maximum number of connections WSA S670 appliance support? Is there any configurable limit for the connections that can be established? Will it cause any issue if a lot of users are watching videos on youtube.
Also the proxy is working in one-armed design. Will that cause any issue?
Please suggest.
Cheers,
Faiz

Does home sharing allow my husband and I to share our itunes content? If so, how do we do that since it requires the use of the same Apple ID and password on each device to do so. His itunes is linked to his email and mine is linked to my email...

Does home sharing allow my husband and I to share our iTunes content? If so, how does this work? From what I've read to use home sharing the devices/computers all require the same Apple ID and password. My husbands iTunes is linked to his email/password and mine is my email/password. So if that's the case how to we go about sharing? God I hope that makes sense.

All apps are forever tied to the Apple ID that bought them. To stop your id from popping up, you need to delete the apps on his phone, and then repurchase them under his account.

HT1420 how do I know what devices have home sharing/iTunes Match. I don't think I have 5 computers setup, but the system says I do.

I like to know what devices I have on home sharing and iTunes Match. Also, how do I increase may access to more than 5 devices if needed?
Thanks

Choose About this Mac from the Apple menu, click on the version twice, append the last three digits of the computer's serial number to http://www.everymac.com/ultimate-mac-lookup/?search_keywords= , load the page, and check the computer's maximum OS version. If that's the current version, click here and read the entire page. If not, you can't use the Mac App Store version.

HT202213 How do I remove a device from home sharing?

I have maxed out my 5 iTunes devices for Home Sharing and want my newest laptop to be included. How do I disable another device from Home Sharing so I can enable the new one?

Yes, sorry for my crossing up terms, there is a 5-computer limit, but after some digging figured out (read: found helpful posts telling me) to de-authorize all computers and then re-authorize my active ones, so now I've got the right laptops authorized to link up with Home Sharing fx.
Thanks!

Does home sharing work between iOS devices

Or is it only from a mac or pc to an ios device.

HI there,
Home Sharing in iTunes is designed to let you easily share your iTunes media libraries between up to five computers in your household. You can also use Home Sharing to play your iTunes content on your iOS devices and Apple TV (2nd generation) if they are connected to your home Wi-Fi network. Take a look at the article below for more information.

Cannot access Home Sharing or iTunes Wi-Fi Sync for any of my iOS devices.

Hey,
I have an iPhone 3GS and an iPad 2, both running iOS5, and the latest version of iTunes for Windows, and had previously had iTunes Wi-Fi Syncing working up until a week ago. Now I cannot even select the 'Sync Now' button on my devices, as they are saying that they cannot access OEM-PC (my computer).
In addition, I have turned Home Sharing on in iTunes, and entered my Apple ID on both devices for Home Sharing, but I cannot access my iTunes library from either devices.
I have followed all the steps that Apple's troubleshooting pages have recommended, but to no avail.
Any help would be greatly appreciated!

A bit more info for those of you reading this.... the problem seemed to be in iTunes. For each connected device , if I clicked on the Photo option I could no longer select the second radio button for limiting the photos by Events, Albums, etc. It was an all or nothing deal. But selecting all would cause the error.
So I had read the other forum posts about the "&" symbol being the cause of the problem. I went through iPhoto and made all of the changes. It did not work. I then looked at iTunes, using the AlbumData2.xml file listed in the other forums as a reference. I found one album with the "&". I edited that one. Still would not work. So then I spent 3 hours on the phone with AppleCare last week. I talked with 4 different advisors. None of them had heard about the "&" error from the forums. We tried everything in iPhoto including repair and rebuild. Finally we created a whole new library and reimported my master photos from my original one. Using this option would allow me to now check off that radio button in iTunes. BUT... I now lost all of my albums and events and would need to rebuid them. I was not happy. They agreed and we set up time to talk this week.
So today I talked with AppleCare again. They now have more info and said the problem has to do with iTunes and the new iPhoto 9.4. It does not like the "&" symbol anywhere in either iPhoto or iTunes. So they now have me going through everything in my iTunes library. Genre is OK but any other item cannot have " & ". I have several dozen to edit and will do it over the weekend and then restore my original iPhoto Library and see if I can finally get it all to sync. I will let you know how I make out, but apparently you need to eliminate " & " from every entry in iTunes and iPhoto.
Quality control is not up to par with Apple these days.

Does Home Sharing not work through a network extender?

Home sharing seems to cut out whenever I get into range of my network extender (Airport Express).
Here's my setup, it's pretty standard: Cable modem wired to Airport Extreme router, which is connected wirelessly to the MBP with my iTunes hard drive. All of this is in my living room.
I use the Airport Express to extend my network into the bedrooms.
Whenever I'm home sharing from my iTunes library on my iPhone, if I walk to my bedroom, it cuts out. It usually crashes the iPod app. If it doesn't completely crash it, I can get it to restart buffering if I walk back to the living room.
Does Home Sharing not work with wireless extenders? Do I have to change something in the set up?

However, when a device goes from being attached to one wireless device to another, there is often an interruption as the device must change the radio connection to the network. There is a brief period of no connectivity (a second or two)
Try starting the share while in your bedroom instead of the living room. I'll bet it works.
Makes sense - so it's a bug in the iPhone OS, that it's unable to recover from temporary interruptions to wifi connection?
However, I'm not so sure. Starting the share in the bedroom works as you suggest (since 4.3.2 - didn't under 4.3.1) - but as soon as you go back to the living room and the iPhone connects to a different base station the music stops playing. Note also that the shared library itself ceases to work. So for example you can't be in one room (on the extender) and add the shared library (without actually playing anything yet) then move to another room (on the base station) and play a track from the shared library. It just plays dead and you have to explicitly reload the shared library to get anything to play.
So is it maybe a bug also with iTunes that it can't keep up with a shared library client moving from one wifi station to another?
How do you report these things to the people that matter by the way?

How many concurrent connections that an ACS server version 4.2 latest patch can handle?

I have about 50 routers and layer-3 switches that autheticate via tacacs+. The AAA server used to be on a Linux machine running open-source tacacs+ built by me. I have a perl script that will log into all 50 devices at the same time to collect statistics. This script is multi-threaded. Everything is working fine so far.
I recently out-sourced the AAA function to a 3rd party company, not by my choice. The 3rd party uses Cisco ACS version 4.2 with the latest patch running on Windows 2003 Enterprise Server with 16GB RAM and quad processors with quad-cores, IBM x3650-M2 hardware. The connectivity between the 3rd party and my company is through a DS-3 connection. Maximum bandwidth over this DS-3 connection is less than 10Mbps at most.
I noticed that for the past 3 months I have multiple failures with this perl script due to authentication failure with the ACS server. If I just run the script again a few routers/switches, there are no issues; however, whenever I started the script to log into 50 devices all at the same time, it will fail. If I made the configuration on all routers/switches to point back to the old open-source tacacs+ server, the issue goes away. The minute I switched back to the
new ACS server, the issue came back. If I modified the script to hit one device at a time, it works fine. I think it is the ACS server can not handle a lot
of AAA requests at the same time.
Does anyone know how many concurrent connections that an ACS 4.2, with latest patches on Windows 2003 Enterprise Server with lot of memory and CPU power, can handle? I can't seem to find this anywhere on Cisco website.
Thanks in advance.

No, Im not saying ACS cannot cope.
Concurrency and latency are very different things. ACS CSTacacs can handle many 100s of simple authentications/authorisations per second with users in the internal database. If 1000s of devices all send traffic in the same instant it would take some seconds to work through the backlog of traffic.
Also, worth considering that a limited number of tasks within ACS (or threads) can actually handle a much greater number of "logins" because they are generally multi-message allowing ACS to keep lots of plates spinning.
If users are in an external databases the latency (per authentication) can increase depending on where the users are (eg Windows AD) and if bad enough can have a serious effect on the overall authentication rate. At which point customers normally turn to load balancing.
If your device timeouts are 20 seconds (totally reasonable) I suggest the issue is more likely to be something else... a bug, perhaps specific to v4.2?

How do you use home sharing if Itunes library is on external hard drive?

How do you set up home sharing if IPhoto and Itunes libraries are on external hard drive?

You might want to start with a new instandce of iTunes - instructions on how to do this is on the web depending on whether you're running Windows or Appls Software. The below URL is one site you can use.
http://ipod.about.com/od/advanceditunesuse/ss/Multiple-Itunes-Libraries-One-Comp uter.htm
Set up your iTunes to utilize the music files on your external Hard Drive.
On iTunes pull down menu select Preferences.
Click on the advanced tab and set the iTunes Media Folder location to your External HD
Click on the File pull down menu and import the folder containing your music into iTunes.
Turn on Home Sharing on your computer - Click on the File pull down menu and click on Home Sharing.
Turn on Home Sharing on your other device(s)
On Music on iPad or iPhone, tap on the More tab and if you set things up right, you will see your Library name. Click on this and if things go as they should, it will connect to your library and you will see your albums, artists, playlists, sogs etc.
Good luck.
