Remote Speaker connection over LAN

Even the Genius bar were puzzled over this one....
I have several airport express's and an AppleTV on my network connected wirelessly and hard-wired to my LAN. I also have an iMac & MBA on the network which both use itunes. The MBA can stream music to all the airport devices with no problem at all allong with iphones & ipads. but my iMac which contains my master library will not play to any of the airports or appleTV when it is connected to the LAN.....?
If I disconnect the iMac from the LAN & access the network wirelessly I am able to stream to remote speakers.
my first thought was to bond my LAN connection to my wireless conncetion, but I lost internet connection when I did this.
Any suggestion?

is anyone aware of any third part applications that allow you to bond a lan & wireless connection? it seems strange that the airplay function works well when the mac is connected to my network wirelessly...
the Apple genus bar have recommended that I take all my network equipment into the store to try and resolve the issue, byt I am reluctant to do so as it is a lot of equipment.

through this applet i am capturing the image and saving in the application deployed directory and accessing this image through a servlet.every thing works fine in my system but when i try to capture from other systems connected through lan the image not saving in my system.
requried solution.

This is might because of you are using applet. Applet runs is client browser. When you runs your program on your system then it saves file on you system but when you access this applet from another system over LAN then, captured will be saved on another system not on yours.
You have to write extra code to upload this locally saved file to your server (i.e. your system.).

Sharing an ISDN connection over LAN

I'm thinking of updating my Main computer and need some advice/help.
Currently I can only get ISDN where I live in Australia, which may be slow but it's also unlimited. I have a PC set up with the ISDN modem (USB connection) which it then shares to the Mac's on the Ethernet 10/100 LAN.
I was considering moving My G4 PowerMac into that roll, but I have several concerns.
First Running does Telstra (Australia) support Mac's running ISDN, their site is unclear. I will contact them to clear this up.
Second how easy is it to share a connection with other Mac's and PC's, can this be done wirelessly also?
But more important how long will the aging G4 last running 24/7, right now normally at night or when not in use (when I go out) I put it in to deep sleep but how long will the Mac last running all the time?
The main reason I need to think about this is the only 2yo PC might have a fault and I don't want to be left Internetless if it fails and I need to think about how to spend the limited money I have. I would prefer getting a cheap PC to use as my Internet and file server leaving my Mac's to actually use everyday. I have not had any security issues with this set up as I have firewalls set up on the PC and Mac's and security software on the PC.

While there are Mac boxes listed at the Telstra Bigpond site, I'd tend to look for an IDSN-capable firewall with Ethernet capabilities.
There appear to be several of these devices around that claim Telstra Bigpond compatibility. Cisco, NetGear, Traverse Technologies, Draytek and other vendors all appear to be in this market.
You'll probably want a network box with an ISDN port (or ADSL over ISDN, depending on what Telstra offers in your area), a firewall, and with some number of Ethernet ports (an Ethernet switch) and/or wireless networking. I'm not familiar with Telstra Bigpond ISDN in any detail, though I'd expect one of these devices to connect into the provided ISDN modem.
Cisco 801 and 803 routers come up in discussions fairly regularly, though Cisco routers aren't the easiest devices for new-to-Cisco folks to configure and manage. And these are comparatively expensive, even if you find them used.
You might also check with some Australian local vendors; there were substantial electronics stores in Sydney and Melbourne. They're likely rather more familiar with the local router/firewall options.

Connecting over LAN problems

Hi, I'm trying to get a sample program going over a small desktop - laptop lan (both running windows 98se and named "desktop" and "laptop" on the network).
The program works fine when both server and client are on the same computer, but when I copy the client files to my laptop and run from there, I cannot connect, and get the following message:
java.security.AccessControlException: access denied (java.net.SocketPermission Desktop resolve)
here are some code snippets:
policy file on both server and client:
grant {
permission java.net.SocketPermission "*:1024-65535","connect,accept";
permission java.net.SocketPermission "*:80", "connect";
server:
Naming.rebind("//Desktop/helloObj", theRemoteObj);
client:
RmIntfc c1 = (RmIntfc)Naming.lookup("rmi://Desktop/helloObj");
I've seen similiar questions about setting up RMI over a LAN on the forums, but there weren't any corresponding answers! I'd like to try the simplest approach, ie, no webserver.
Thanks for any help!!

Hi
The problem is probably with the client-side permissions rather than the server. It may be that the permission file that you've set up is not being used, or that the permission syntax is not quite correct.
Try granting AllPermission to all codebases (on the client) and see if you can get the system working. Once you get it working, then you can be more selective with the permissions.

WRV210- Can't establish Remote Desktop Connection over IPSec

Hi there,
I changed the BEFVP41 with WRV220 and configure the VPN the same way, succeed to establish IPSec VPN connection with TGB VPN client with no problems but now Remote Desktop Doesn't work. I changed the firmware that didn't help. That didn't help as well, the answer is the same:The client could not connect to the remote computer. Remote connection might not be enabled or the computer might be too busy to accept new connections.The Remote connection works fine in local and with BEFVP41 (even thou I had different problems with this one) the only change is the WRV210....Did you have this issue?
Thank you
Vesna

As a sort of work around, you could configure a dhcp reservation for that pc. Leave the machine as dhcp but know that it will always "recieve" a specific address. I think the problem the WRV210 experiences in this situation, is the mac address table times out and it flushes the pc's mac to ip binding. Therefore, it does not know who to send the request for X ip address to, because it no longer has a mac to port mapping.
However, when the router has the client via DHCP, the dhcp protocol takes care of making sure the mac does not time out in the CAM table. When the lease is somewhat close to expiration, the client renews and everything works fine. You can staticly map up to 20 addresses in the WRV210 (confirmed with configuration in lab).
With this solution, your RDP sessions and port forwardings will continue to work, and your mac will never timeout of the CAM table.

Remote Speaker connection?

Is it possible to get Garageband to find and play through wireless speakers plugged into my Airport like iTunes does?

The problem is that to send the audio it would have to come out of garageband be turned to analog "no problem yet", compressed, turned into radio waves, picked up by airport express, turned back into analog and then sent to amplification and speakers. No matter how fast this gets there is still a little time delay... well for now, who knows maybe someday.

Problem Establishing Remote Desktop Connection from Win 7 64Bit

I just got a new Lenovo laptop running Windows 7 Pro 64 Bit with Service Pack 1. I have installed all Win 7 Updates.
When I try to connect to other Windows 7 Ultimate (32 bit) desktops through Remote Desktop Connection over my LAN, I get the following error:
"An authentication error has occurred. The requested security package does not exist"
I can connect to a Windows Small Business Server 2003 32 bit server from the laptop without problem.
All machines are members of the same Windows domain.
The Windows 7 machines I am trying to connect to can connect to each other without issue. NLA is set as not required on each of the desktops, though I have tried turning the NLA setting on, and received the same error.
I have even tried running the 32 bit version of mstsc.exe and disabling the 64 bit version as discussed here:
http://www.davidmoore.info/2009/12/02/running-32-bit-remote-desktop-connection-on-windows-64-bit/
This had no effect either.

Hi,
Based on my research, please check whether the value of HKLM\SYSTEM\CurrentControlSet\Control\Lsa\Security Packages is
kerberos

pku2u
If not, please correct it and see how it works.
Note: Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

-3256 Error - Unknown error, cannot connect to remote speaker

I recently bought time capsule and have set that up as a base station. The input to time capsule is the linksys modem + router. I have disabled the linksys router capabilities and am only using that as a modem. When i connect airport express to the time capsule network, i get a error message stating -3256. Unknown error cannot connect to the remote speaker. Before time capsule, linksys network was able to play airtunes, but time capsule is not able to. I have disabled the firewall on both time capsule and linksys.

It might actually be the firewall on your mac rather than the other hardware. I mysteriously started getting this same error when trying to use the Multiple Speakers function with AirTunes (had worked perfectly for over a year). I modified the Security/Firewall settings in System Preferences and it started working again, no error: I simply added iTunes to the "specific services" firewall list to allow incoming connections. Of course the firewall is set up quite differently in 10.4.x.
You'd think that checking "look for remote speakers" in iTunes preferences would take care of this for you, or prompt you to make the changes yourself (I remember getting OS messages that used to say "if you want to do such-and-such, make sure you open port xxxx") but apparently not!
I also read somewhere that checking "share my library" in iTunes prefs can help with this sometimes, but I can't verify that - I already had it checked; it was the OS firewall tweak that worked for me.

Remote Speaker (AirTunes) Error - "the network connection failed"

I am getting a strange error message when I try to stream music through an AirTunes remote speaker. iTunes tells me this:
*An error occurred while connecting to the remote speaker "NN". The network connection failed.*
I can't say what has changed for this error to occur. Last time I used the system it worked fine, now it doesn't. I do know I have upgraded iTunes a couple of times since, though.
I am connecting to an 802.11g AirPort Express running firmware version 6.3.
Both our computers (MacBook & MacBook Pro) run Mac OS version 10.5.8.
In my system, the AirPort Express functions solely as a wireless speaker client, as the WLAN network itself is based around an 802.11n AirPort Extreme.
The AP shows a green light, and reports no problems in AP Utility.
When I change the device's "iTunes Speaker Password" setting in AP Utility, iTunes in both our computers immediately reflect the change, so apparently the various parts in the system do speak to one another just fine. They just can't transmit music, for some reason...
Anyone have any idea what might be going on, here?

I have a similar problem. I use AE(g) with a Powerbook G4 and always get this error, which kind of bugs me, since all the settings appear to be correct. Unlike you though, I didn't make it work, not a single time — closing lid, opening and closing iTunes, resetting AE, yet no luck. Tried it all only with current versions of software.
However, the AE does sense when I unplug the speakers, since it first says "no speakers found", and then "the network connection failed". Strange is that the error has no number, nor does Console provide any clues. Sometimes it is pretty annoying when OS X just says "error". What error, where, why... Feels like good ol' windows times.

Connection to a remote speaker almost impossible

Ive just bought an Airport Express few weeks ago and its still almost impossible to get a reliable connection to the remote speaker from within iTune 5.01.
The Airport Express is connected as remote station to an Airport Extreme base using WDS.
When Im trying to connect to the remote speaker, Im getting the message that the remote speaker is already used by another computer. Since Im also using a PowerMac G4 (running 10.3.9 and iTunes 5.01) at home, Ive switched off this machine, switched off and on the Airport Express : most of the time Im getting the error message.
After this few weeks period, I would say that rate of successful connections is less than 10 %. I wasnt able to determine why the connection is suddenly working
Any clues are welcome
Cheers
Pascal

But the issue is I need to connect to the remote
server and not my local machine. What am I doing wrong
in the connection string?What you are doing wrong is assuming you can use a "remote DSN". If you're connecting to a DSN it has to be on your own machine. You may be able to make that DSN refer to a database on another machine, though.
You also mentioned a "remote server". You're also making a mistake in assuming such a thing exists. Other databases have servers but Access doesn't.
The simplest thing to do, probably, would be to map a drive to the machine where your remote Access database is located and then to use a DSN-less connection to it. I don't recall just how you do that but if the forum search facility is working then you should be able to find out, as that information is posted here frequently. Or you could use Google, and it will usually give you links to this forum.

Error message (-3256) appears when connecting to remote speaker

An error occured when connecting to remote speaker. An unknown error occured (-3256).
ANy help would be most appreciated. Thank you.

I get the same message and have been stuck with this for weeks since upgrade to iTunes 8, now running 8.02 and did a firmware upgrade on airport express to 6.3 but still no joy...anybody got any other ideas ? I'm about to give up and move to sonos

An error occurred while connecting to the remote speaker. The network connection failed.

I can't get my itunes to connect to the remote speakers via airport express anymore - I did not change any settings - but did update iTunes to 10.2.2 and now things are not working and I get his message - "An error occurred while connecting to the remote speaker “Living Room”. The network connection failed."
Does anybody have a fix for this problem?
thanks

Same problem for me. Ever since I upgraded to 10.6.3 and iTunes 9.1, about once per week I'll get the error message when trying to get iTunes/Airtunes to connect to my older Airport Express (running firmware 6.3) "An error occurred while connecting to the remote speaker <insert speaker name here>. The network connection failed." (No error codes are given.)
Airport Utility sees the offending Airport Express just fine (and there's a green light on said AE).
Curiously, a newer AE-n, elsewhere in the house (running firmware 7.4.2) does NOT exhibit this problem.
Simply restarting the offending AE does NOT clear the problem. Restarting the main router - a Time Capsule DOES clear the problem. Alternatively, toggling off the Airtunes functionality on the offending AE, restarting it, then toggling Airtunes back on, and finally restarting it DOES clear the problem (as an alternate to restarting the router). No matter how the problem is cleared, it returns within a week. It's frustrating that the problem cannot be recreated immediately.
Probably not relevant, but the computer on which I'm running iTunes (a Mac Mini) is connected to my TC via ethernet, not wirelessly.
I've tried the suggestion of disabling ipv6. No effect.
I fear the only solution will be to scrap my older Airport Express and replace it with a newer n-model. But before I resign myself to the $100 fix, any more ideas?

Itunes and network connection for remote speaker

I have three airport remotes that are all on line. On one of my computers when I try to access a remote speaker I get the message "network connection failed." I can play all three remotes from other computerswith ITunes but my main computer cannot access the remote speakers. Any suggestions? Thanks

I have the same problem with my computer running windows 7. I get the following error message; "unknown error -15000". The connection does not get established with my remote airport express access points
