Multiple production clusters on the same network? just change UDP port?

If I want multiple production clusters on the same network do I just make sure each cluster is on it's own multicast port? or are other changes required?
Thanks,
Andrew

Hi Andrew,
I think to be safe it would be best to use a different address and port.

Multiple Apple TVs on the same network

I teach at a school and have used an Apple TV in conjunction with my iPad for presentations. I find it invaluable. Other teachers at my school would like to do the same, but I'm told by our tech support that multiple Apple TVs on the same network cause problems. When I ask them what problems, they aren't sure. They just tell me that other school have experienced problems. Other than a wifi bandwidth problem, I can't imagine what kind of problem it would be. A collegue of mine wants to jump onboard but desn't want to make waves. Does anyone know of any problems?

I have two Apple TV's, one in the living room and one in the bedroom... however, the living room is the only one that my iphone Remote APP is connecting with... I've named/tagged the two ATV's hoping that the Remote APP would provide me the option on which one to control, but it doesn't....
I've confirmed that home sharing is "on" with in all devices "settings"...
Any suggestions?

Two independent clusters on the same network

Hi,
How do I configure Coherence node VMs to participate in different coherence clusters on the same network?
Thank you.
Roman

Hi Roman,
You need only have each cluster running on a different multicast address. You can accomplish this by either modifying the <multicast-listener> <address> element in the tangosol-coherence.xml file. Or you can override this value by using the following java command line argument -Dtangosol.coherence.clusteraddress=<IP_ADDRESS>

Can I use multiple sa-ns500 on the same network?

Is it possible to use multiple sa-ns500 speakers on the same network? they seem to want to have the same name on the network and therefore only 1 will connect at a time? Can I rename one somehow? Thanks!

Hello Brian,
Welcome to Sony Community.
Please check for the Secure Link option in the Home Theater System or A/V Receiver. This will help isolate the connection to the different Network speakers.
Yes, you can use multiple Network speakers on the same home network.
You can change the Device name using the Setting screen on the browser.
Follow the steps mentioned on the page # 34 and 35 of the User’s manual to start up the browser of the Network speakers and change the Device name.

Multiple Discovery Systems on the same network

Is anybody successfully running more than one DS on the same network? We have edited the hostname of the DS but their still seems to be a conflict between the two servers and the SID names cannot be the same as well.

Hi Phillip,
The changing of the hostname is not recommended by SAP, but there is a customer who succeeded in doing so and claims to have even connected 4 Discovery Systems to the same network.
Knowing Maxim, I believe he indeed achieved it.
Read his blog: /people/maxim.efimov2/blog/2007/05/07/how-to-change-hostname-on-sap-enterprise-soa-discovery-system
My only tip: make a backup of the systems before you make any significant changes.

How to configure multiple clusters on the same machine.

I am attempting to configure multiple clusters on the same set of machines. I have set the cluster name and multicase IP addresses to be different for each cluster. However I am still getting and error that states:
"This indicates that there are multiple clusters on this network attempting to use overlapping network configurations."
Is this not possible? If it is possible, is there some further way i need to tell the VMs they are part of different clusters?
Thanks,
Jacob

FYI: I'm using the wrong multicast IP above. 224.0.0.1 is reserved and something else should be used. See:

Multiple Apple TV's on the same network with airplay issues.

I work at a school with 37 Apple TV's. They are all on the same network, some of them are wired while others are wireless. The problem I am having is that airplay works and then doesn't work for some unknown reason. The Apple TV's are connected to the network and internet when they are experiencing this and I believe that the issue is bonjour. Does anyone know any way of solving this issue.

Yeah, I think wiring them is the only solution to this problem.
We've only got three (well, had one and bought two more this summer - that's when the trouble started).
The first one I got had trouble connecting with the wireless network, so Apple support said to reboot the main router. That is, shut down the entire network while we reboot for one Apple TV. So...OK, I get it, Apple is a CONSUMER company and we're trying to use their products in a school...in spite of that, so far, it has been worth the effort.
But YESTERDAY I got that message about too many devices on the network and to "disconnect a device..." (you know the rest).
So, I called Aruba, knowing that it was a wireless issue and that I've had issues with them and, particularly
Bonjour. Aruba appears to be a Windows only network - would that I would have known that three years ago. But Aruba TAC has NO CLUE what the issue is. So I called Apple Tech Support and they have NO CLUE - weren't even aware of this posting, what, six months ago? (Shows you how much they read and value the forum - we're on our own, boys and girls!)
So...I wired the front of the school Apple TV to a nearby wireless access point and now it's a steady as a rock. But prior to that I actually stood in front of the ATV and watched as it connected, then disconnected, then connected, then disconnected (ad nauseum). Interferrence? Well, maybe, there are only about 150 rogue networks detected in the immediate vicinity - but Aruba ASSURED ME that their WAPs were sophisticated enough to recongnize that and filter them out. (Maybe not?)
So the ATV at the front of the building ocassionally just drops off the network. I can tell because we run a Flickr slideshow on it all day long with announcements and stuff. When I go by the TV and see the thumbnails and no slideshow, I know it has dropped off the network. Usually I can reconnect it. But that's not good enough.
Finally, yesterday, a teacher called me who has an ATV (long story on how she got that) and said she was not longer connected to the network. A shudder ran through my body as I expected (and realized) the worst.
So, my installer is coming tomorrow to wire her ATV into the WAP in her classroom. But TODAY, I have to call Aruba and enable the additional port since it's not enabled by default.
I'll tell you, every day, I get this horrific feeling in the pit of my stomach that this whole world of technology we have built is held together with bailing wire and duct tape and that it just has to blow at some point.
Then I watch Bob Ross do his paintings (and a NEW KID on the block - watch out for him - Kevin Hill - this kid takes Bob Ross to the next level and he's only 18 years old) and think - "What the heck am I doing here, anyway? Why am I not home painting?" But them I start feeling guilty that I'm leaving the school in the lurch. Who will stand up to these bozos who don't have a clue what's going on and, further, don't seem to care, yet, get this, think they are doing a GREAT JOB! I'm telling you, I'm living on Superman's Planet Bizarro!

Solaris 8: Multiple primary interfaces connected to the same network

I have a machine with Solaris 8, and it has multiple interfaces that are connected to the same network which means they all have metric 0 (1 hop) to the default gateway.
assume:
e1000g0: 192.168.30.70
e1000g2: 192.168.30.72
e1000g4: 192.168.30.74
e1000g5: 192.168.30.76
gateway: 192.168.30.65 (Cisco Router)
However, it seems like despite the fact that they have a direct connection, they seem to be using e1000g0 to access the 192.168.30.0 network to get to the default gateway and then to anywhere else.
When I send a ping to say, 192.168.30.74 (IP of e1000g4) and capture packets on e1000g0, I see the "echo reply" messages going out of it as opposed to e1000g4 even though e1000g4 is the one receiving the "echo request". This should not happen and these should be completely independent as they should all be advertising a 1 hop to that network
The outputs from netstat -rn and ifconfig -a are shown in the picture on the link below
[http://img836.imageshack.us/img836/7308/ifconfignetstathiddenip.jpg]
This gets even more confusing when I go into the Cisco router and run the command: "show mac address-table" where only the MAC address of e1000g0 is shown for the switch port it's connected to, but not for the other interfaces which are connected to the switch. Yes, all ports are active (no shut) and are pingable.
Also, the odd thing is that ALL of these individual MACs show up in the router ARP table when the machine comes up, however after sending a ping to one of them, after a certain expiry or whatever period, the MACs disappear from the router ARP table and only the MAC for e1000g0 shows up. The arp table of the solaris machine however shows all the relevant MACs of each port of the router that it's physically connected to (This is actually a Cisco Switch with the advanced IP services imagine and L3 routing turned on)
Before anyone asks: The setting local-mac-address? setting does NOT exist in my machine and it never has, but it used to work fine. Also, from the ifconfig command, once can tell that all the MAC addresses are fine.
I need to somehow assign all these interfaces equal priority and make them understand that they're physically connected to the 192.168.30.0 network and there's no need to go through e1000g0 to get to it.
This is causing a lot of problems as eventually all traffic will end up going through the e1000g0 interface and that will become a bottle neck.
Please help Thanks in advance

Ok thanks. That was a useful response.
I did think about the trunking software that is claimed to be available for Solaris 8, but it's only available if you've got paid support contract. Oracle came and ruined everything re: Sun support which is so expensive now.
The other confusion is, we never had that OR needed to configure trunking/link aggregation on this machine, so why now?
Lastly, by your explanation, this should be expected and is "normal" behaviour, which would mean that this machine was always doing this and I only just noticed it this time? I thought if you turn off ipv4 forwarding and router function in the machine, it's every interface for itself. But it's not doing that :(
So then the question is, Can I force it? I've tried a bunch of things by manipulating the tables and it seems to mess things up where nothing is getting through or it now shifts all the traffic to some other port make the problem no different
Is there a way to give equal weight to all interfaces for the traffic to go directly through them that is originating at those ports?

Connecting to multiple clusters from the same client

We have a scenario where our cache client (extend client) should be able to connect to multiple clusters. All the clusters use the exact same configuration (same caches, same services etc) but running in different geographical locations. I know that the <remote-addresses> can be used to add multiple addresses but I'm assuming this is provided solely for fault tolerance. So, does the client actually support connecting to multiple clusters at the same time?
Thanks
Sijo Mathew

Hi Sijo,
Normally to connect a client to multiple clusters you would just define multiple <proxy-scheme> settings in your client configuration file, each one having a different name and pointing to a different cluster. You then map caches to the proxy-scheme for the cluster those caches live on.
What may confuse things in your case is that you say the different clusters are identical and contain the same caches and services so you may have problems mapping caches on the client to different clusters.
What are you trying to achieve by doing this if the clusters are all identical?

I have a iPhone 4S and a Cannon Printer with AirPrint. I have the printer and the iPhone both on the same network, however I still can't locate the printer on the phone. Works just fine with the laptop on the same network. Any suggestions?

I have a iPhone 4S and a Cannon Printer with AirPrint. I have the printer and the iPhone both on the same network, however I still can't locate the printer on the phone. Works just fine with the laptop on the same network. Any suggestions?

ok no problem! all i did was 1) set up the mobile hotspot on my phone. 2) turn it and wifi on on the phone. 3) connect the laptop/desktop to the hotspot network. 4) insert setup disk for the printer and begin setup. 5) complete the setup "using a usb cord to temporarilly connect the computer and printer" 6) unplug usb cable and finish set up on the laptop/desktop. 7) give it a few minutes to show up on the AirPrint menu on the phone. 8) that should be it. I unplugged the printer and plugged it back in, made sure the laptop was totally turned off AND disconnected from the network, and did everything I could to try and make it not work. The printer I have is a Canon MG3122, it doesn't have a fancy screen or even a way to input a password or anything like that, so it just strores a default network that it will connect to. in order to change networks i would have to complete setup multiple times. Since I only plan to use it with AirPrint for my mobile business....the one network is just fine! Hope this helps!

Multiple Users Mounting the Same Network Share?

Hello, first time posting...
I'll cut right to my main question: Is it possible, on OS X v10.3.9, for multiple users to simultaneously connect to the same network share?
Here in my office, we have a single Mac that is used by multiple people throughout the day. It has two accounts on it, 'Communications' and 'Studio'. 'Communications' is an Admin account that is used by a co-worker who spends the most time on the Mac. He created the no-limitation 'Studio' account for the rest of us to use.
There is a certain Windows network share that we both frequently use. We've found that if one user connects to the share first, the other user will not have access to it; using 'Go -> Connect to Server' will result in the share being greyed out in the list, and the share will not show up in the Finder.
However, there is one way around it. If Studio connects to the share first and then Communications (the admin account) attempts to make a connection of it's own *through a shortcut on the dock*, then a 'clone' of the share will be created on Comm's desktop, with a "-1" after the name (though it might be some other number).
This may sound like I've answered my own question, but what I'm looking for is a way for the non-Admin account to access the share after the Admin account already has (so that we don't have to log-in and disconnect Communications everytime Studio needs to manage files on the share).
We have Thursby Software's DAVE installed on the Mac, but I'm not sure how it fits into all this.
Any thoughts, suggestions or advice?
Thanks.

Bizarre. It turned out I could merge them, but only in to the mapped drive - L: - and only by explicitly clicking on the drive icon - if I typed L:\series in to dialog box it converted it back to \\nas\share\series... Not helpful.

WLC-2106 and multiple interfaces on the same network

Hi there,
I recently created a TAC request to the Cisco support regarding our WLC-2106, but they could not help me. Basically I just learned that you can create new interfaces for the wireless LAN controller and then dedicate them to a given wireless network (SSID). This way I could more effectively utilize network bandwidth also. Problem is that all of the interfaces have to be in a different network segment in order to work, which is not what I want. I specifically want to have several interfaces on the same network segment.
Has anyone tried to accomplish the same?

Basically what I've misunderstood is that all the traffic generated by our wireless clients have been going through the single 100Mbit/s ethernet port on the wireless LAN controller (management interface), and to mitigate this I thought I could create new interfaces (ports) and dedicate those to given WLAN networks.. I see now that this is not supported. Not inside the same network at least.
So, by reading further and consulting my best friend Google I learned about a setting called "AP Mode". Changing that from Local (the default) to H-REAP the APs should not route their traffic anymore through the management interface on the wireless controller, but instead route all the client traffic directly to the local LAN. This way you effectively remove the 100Mbit/s bottle-neck when all the APs were using the management interface both for configuration and client data traffic.
It seems you also have to enable H-REAP Local switching from a given WLAN network in addition to changing the AP Mode of your access points to H-REAP. I'm still in the testing phase here so should anyone have any insight to this, I'd be greatful to hear more.

I just upgraded to mountain lion. I am unable to use airplay mirroring through my apple tv. They are both on the same network. It says a airplay icon should appear in the menu bar but it isn't there. What am I missing here?

I just bought Apple TV 2 can I still use apple tv on the same network?

I just bought Apple TV 2 can I still use apple tv on the same network?

Yes, no problem at all.
AppleTV 1 should still appear in the same itunes it syncs/streams from.
For AppleTV2 you must enable Home Sharing on it and in iTunes, but you dio not see it as a device in itunes.
