Connection dialog between 10.5.5 client logging into a 10.5.5 very slow

when attempting to connect via afp to the local file server, connection authentication dialog seems very slow (about 30 seconds)
using a 10.4.x client to connect to the server everything is immediate
using a 10.5.x client to connect to another 10.5.x client everything is immediate
using a 10.5.x client to connect to the 10.5.5 server takes minimum 30 seconds to show login prompt.
once connected, server speeds are perfectly fine for reading and writing.
Any thoughts?

You'll most likely get a cogent response posting to the appropriate server products forum.

I have connected my ipad to my computer and logged into iTunes website. On my iPad to restore my my data Ipad I have chosen language, country then it asks you to connect with cable and log into iTunes, I have done that, but cannot find this other information I need to restore from the website. Can you help me please? the 2 replies, I thank you, but this has not helped with my problem.

Your post is somewhat confusing. To restore your iPad you use the iTunes application on your computer and connect your iPad. Select your iPad in the left column of iTunes on your computer and select General in the right column. You should find the restore choice there.

Just make sure if it wifi is connected. if this doesn't work reboot your iPhone. If it's still doesn't work contact the game service center or something. lastly, make sure u have your credit card sign in. hope this help.

How to resolve on my iPad: Unable to connect to server error when trying to log into Game Center?

When I try to log into the game center, i get an error message that says: unable to connect to server due to an error communicating with the server.
I have logged off iTune and any other app I was logged in, I have done a hard reset of my iPad, I have reset my modem, but nothing had any impact and I am now frozen out of my game center.
Anybody has an idea of how to resolve this?
Thanks,

1) May be there is a mismatch with the jar file name and the filename in the jad properties ( happens only if you rename the jar file)
2) Check hollywood jad properties and the ringtone jad properties. May be the complete url is required for the jar file.
3) If you are using any restricted APIs in your midlet, then make sure your jad properties has the required permissions.

Local KDC (LKDC) relating to Leopard clients logging into Tiger Server

This is a follow-up to my posting on this thread:
http://discussions.apple.com/message.jspa?messageID=5982070#5982070
Pursuing the problem I had when I upgraded to Leopard, I found it odd that trusted binding to Tiger OD from a Leopard client created a funny computer entry in the Workgroup Manger (WGM). Previously when using trusted binding from a Tiger machine to a Tiger server, one entry would be created. And Logging in as an OD user worked every time for me. However, it appears that under 10.5.1 Kerberos has changed significantly in that it is now being used extensively through the Leopard OS for Peer-to-Peer applications. This may account for the screwed up Computer account entries in WGM when a 10.5.1 client binds to 10.4.11 Server using trusted binding. The giveaway clue to this is the LKDC:SHA1 entry created in the WGM computer record (usually 3 seperate records for 10.5.1 instead of the normal single record with a Tiger client). My question is this:
Are there any changes that can be performed via command line on the 10.5.1 client to mimic the old 10.4 client Kerberos configuration without pervasive Peer-to-Peer use of Kerberos? Is is a config setting for the mit.kerberos file? Could it be as simple as flipping a switch to get the older more compatible Kerberos config of a 10.4 Tiger client? Can I dump the Local KDC present in Leopard, and get back to the good old days of non-local KDC under Tiger?
http://www.afp548.com/article.php?story=LeopardServerReview-LocalDirectory
"The Local KDC
Yes, you read that right, the local KDC. All Leopard client systems will now create a Local KDC for use with peer to peer file sharing.
While this isn't even as close to as scary as it seems, it is a topic worthy of at least a separate article, if not a whole series. I put on my thinking toque and sat in my thinking corner for a while on this, and I've not yet been able to come up with a reason for why having a KDC on every machine is less secure than how 10.4 did things. Having said that, though, I fully understand how this can seriously freak out your network security team as they don't quite grasp all the ins and the outs of this. Combine this with Back to My Mac, another article that's forthcoming, and you have a very interesting collection of some "sleeper" features in Leopard.
So, in a nutshell, a Local KDC, the LKDC, is created when 10.5 is installed. Local users will get LKDC authentication authorities allowing them to get Kerberos tickets and use that for single sign on to all the services hosted on that client system. Kerberos is supposed to be only used when you use Bonjour to discover the other machine. So primarily in peer to peer on the same LAN cases.
It works, you can see this for yourself. Screen share to another machine as a local user by picking the machine out of the sidebar in the Finder. You'll have to enter in your password the first time, but after that you can close out of that screen sharing session and restart it without having to re-enter your password. You can also see the ticket in the Kerberos.app, still buried in /System/Library/CoreServices."

Eric,
Thanks so much for your thoroughness and assistance. I think we have decided, for now, to forgo the 10.5 clients attaching to the 10.4 server because of too many intermittant issues. Similar machines on 10.5 gave different results. And at this point, our client is very skittish about the process working at all. I think we need more testing and that is the directon we'll take for now.
Here are some of our results:
I did find information on afp548 regarding the 10.5 preference. It was specificall referenced in this article:
http://www.afp548.com/forum/viewtopic.php?forum=18&showtopic=16064
Clearing the check box on the 10.4 server under OD > Settings > Security "Require password change on new user login" did solve the memory issue that kerberos was having. After clearing the setting, I:
* deleted all binding references at the server (WGM > Accounts > Lists > All Computers
* Deleted the bindings at the client and the the LDAP server references in Directory Access
* Restarted the machine
* Reconnected the LDAP server, Rebind the machine
* Check the LDAP search in issuing id <username> in Terminal
* OPen System PReferences > Accounts > Login Items, the preference is there!
* Yeehah
Oh, but the user still can't login in that machine. Uhm, why? I have no idea. I take a new machine, 10.5.1, no login accounts except a local admin, and no that user still cannot login. Other users, no problem, but not that user.
Take a new system, 10.4.11, set up the binding, the LDAP server, try to log in that same user: works every time. Ugh.
So of course, I think there is something up with that user, but nothing in logs gives an indication of what is going on. That I can find. THis is after 10 hours of testing and trying. Needless to state, the client is frustrated, and so am I.
You know, we do have one 10.5.1 client laptop that did work. After lots of binding and rebinding, it just somehow starting working as expected. But, the reason that we're sticking with 10.4 clients for now is that machine will not respond to password change mandates. I select that user in the WGM, check the "require password change on next login" and nothing happens on their end. They are not an admin, I have reset their account more times than I can count, and so I expect there are more non-working items with 10.5.1 clients and 10.4 server that will get me. It needs more testing for now.
So, back to your message, I haven't tried the SSL certificate, but I will give that a try.
In general, for your network, how are your laptop users configured? As mobile users? Network homes? Or Local homes?
Thanks again for your help. I really appreciate it.

Why can't I connect to the wi-fi when I log into Windows 8 on my mac? It says no wi-fi networks available.

I cant connect to the network when Im on windows 8!

Did you install the Windows Support software in accordance with the Boot Camp instructions? if you did, then I suggest you visit a Windows forum to troubleshoot wifi connections in Windows. Or, use the Windows help menu for setting up wifi in Windows. And, make sure you provide more info regarding your issue. What happens when you try to connect? What error messages do you get? How is your wifi set up and configured?

Kapsel Fiori Client (FC): self-built iOS FC shows very slow UI performance

Hi Experts,
I have used KapselSDK to build our own FC using:
SMP3.0 KapselSDK SP07_PL00
Cordova 3.6.3
Xcode 6.2
OS X 10.10.2 Yosemite
Enterprise distribution certificate for deplyment
.ipa for iPhone4S, 5 (tested)
ipd also inside Airwatch (tested)
App config:
SMP proxy is not used.
The issue:
We use FC to launch the Fiori Launchpad where there are some Fiori apps. The problem is that after type usr pwd, it took very long time to see the Launchpad UI. Tried the standard FC from Apple Store, and it worked very fast.
Does anyone have any idea? I see some info about the slow UI performance for Android devices which can be solved using crosswalk, but my understanding is that crosswalk is not for iOS.
Thanks.
Dong

Have you tired testing the same URL through Mobile Safari to see if it is slow also?
We have had reports of slowness on iOS and we are researching. The details are iOS uses HTTP pipelining when the connection is slow. This means iOS bundles several requests (2-3 to our observations) together but the ICM does only response to one of them and ignores the others. After a timeout of about 1 minute (transparent to the FLP) the Safari automatically repeats the ignored requests. It may happen that this happens a second time, but not a third time – then the requests are not repeated anymore. Seems to happen in Mobile Safari Browser more often than Fiori Client and doesn't happen in Mobile Chrome on same device.
Thanks,

Cannot log into Oracle over WAN between different Domains

Essentially, the Oracle database server (serverA) resides in the domain remote.xxx.net which is part of the Remote (German) forest. We have our own domain, which is not currently part of the Remote forest, thus there is no transient trust between the two domains. When the client logs into our domain here (i.e. behind the ISA firewall), and starts Pro/I, the Oracle client seem to automatically forward authentication requests to our LOCAL domain controllers, and NOT the authenticating domain server serverA. As the user does not exist in our domain, the authentication fails.
So, this would indicate we have to somehow configure the Oracle client to force it to authenticate against a nominated domain (remote) and not against the domain the client is logged into, if this is possible. Again, my Oracle experience is limited, so we will investigate further, but if anyone has any other ideas, we're open to trying them.
Regards
Michael

Loos connection trougth a firewall between oracle server an client after 10 minutes

hello,
i do loos the connection between oracle server an client, because the firewall is between. The firewall will close non active connections an ports after 10 minutes. Only port of one site is clost after 10 minutes then, other site let the port open.
Shares to the the server do in not loos. Only connection to oracle. What can i do !!!!

I had the same problem and I guess you are also hitting the firewall timeout problem... you can enable Oracle DCD (dead connection detection) by setting sqlnet.expire_time in $ORACLE_HOME/network/admin/sqlnet.ora appropriately. This solution I got from http://asktom.oracle.com.
I tried setting the expire_time to 50 minutes less than firewall time-out (which is 60 minutes) but it didn't worked, right now i am trying to figure out what else can cause the problem (I am using Oracle connection pool).... but I think above solution may solve your problem

Connection timeout depending on how many client JVMs (but as many requests)

Hello,
sorry for the cryptic title, I hit the length limit.
Here is my problem. I'm asking first for an explanation, or for ways to investigate it. Afterwards I'll need a solution but as I suspect the problem is involved, and involves several tiers, I will probably open dedicated topics instead.
Short Story*: a web service server and 10 test client JVMs work fine - but a single test client simulating 10 virtual users experiences ConnectException.
What can I log or probe to understand why?
Long Story*:
I have an application that I used to simulate load on a WebService server. The app simulates a variable number of clients of these WebServices, each virtual client running in its own thread, and sequentially calling the same set of WebServices in a fixed order, and looping.
I have, on some occasions, met various problems with the server product (under development and validation), or the test client (that may not have had the same level of attention and quality in the design as the product), some of you may remember some of my asking here and there. But we achieved a fair level of reliability.
However, today, after a few weeks' change to the server(1), we load-tested it using the test client simulating 10 concurrent clients. After a few minutes, we repeatedly witnessed a fair number (1% of the requests) of java.net.ConnectException "connection timed out" raised at the client's end. I immediately suspected the server to not honor connection requests timely, and went on monitoring the server's queues, listeners,etc.
As nothing seemed to highlight a problem on this side, a colleague suggested that we instead launch 10 client JVMs (on the same single test client machine), each one simulating one single client. I blatantly qualified his suggestion of "hopeless random try" but let him try his way.
Dang! He repeatedly demonstrated that the 10 client JVMs do not undergo the ConnectException, even though they simulate the same number of concurrent requests (well, 10 at most), at the same thoughput - and we observe the same level of server CPU, and same functional results.
I respectfully apologized for being a pretentious moron (2), but he hasn't proposed any satisfactory explanation so far, and I'm clueless too. So we haven't been able to make the "single JVM load-test client" work. We need to make this one work, for various reasons.
There may be some server-side tweaks (worker thread pools, waiting queues,... for the record it's a Glassfish server) that I may tune, but as the "regular" situation of 10 client VMs is handled appropriately, I deem the server-side setting are correct.
So I'm primarily interested in monitoring the client host and JVM(s) to spot the differences between the two scenarios. But there may be some server-side indicators as well (queue size, keep-alive pool) that may help the investigations - and if need be, I will happily tune the server for the benefit of the "test client investigating".
One track I'd like to investigate, is the way HTTP connections are reused: we're using a JAX-WS client querying a Glassfish server, and both seem to agree on using HTTP1.1 (I checked HTTP packets with tcpmon), which supposedly "reuses connections" (is that the same as "keeps TCP socket open and reuses them"?). Could it be that the 10 threads in the multi-client simulator have a bottleneck of using a shared HTTP connection(s)? I don't know how to log or monitor this:
- I did a couple of netstat dumps during the tests on the (Windows) client test machine, and it exhibits only a few hundreds of sockets in TIME_WAIT state, and a few dozens of ESTABLISHED ones.
- I don't have the numbers for the server, though.
I don't know how to investigate that further. Any clues?
I may exhibit a poor turnaround time in this thread, as the test platform is used for real tests, but I do care about the topic, so I attach shiny little dukes.
Thank you for your time (well if you've read this to the end you at least deserve a thanks!) (3)
J.
(1) and after switching test platform (room & network); lesson one: "Never mix test platform changes and other changes in the same iteration; regression-test the new test platform with the former software version"
(2) lesson two: "When you don't know, don't tell a colleague he doesn't know"
(3) lesson three: "Short posts get better attention, are better understood, and more happily replied to"... (sigh)

Hello ejp,
I not only missed your points, but missed your latest post as well :o)
I'm discovering it.
You've missed the point. Problems that only shows up with multiple clients in the same JVM but not with multiple JVMs don't correspond to real-world situations any more than the configuration does so there is little in even investigating them, and no point whatsoever in trying to fix them.
(...) It's not 'hopeless', but you have to be constantly aware that it can lead to false positives and false negatives.Fixing them woud enable me to continue load tests with a cheaper test platform. I cannot afford 10, 100 or 1000 client machines. I know you're talking about JVMs, but 10 or 100 client JVMs running on a single host is not a real-world situation either, no more than "all clients are on the same LAN". I have to do away with approximations, keeping aware as completely as possible of the differences it introduces.
This is not true for HTTP connection caching: this favors the server as much as the client, so I can't infer that it's a favorable case overall.Again you've missed the point. It can only happen inside a single JVM. So it may present you with false positives.I'm still not sure I got the point now:
-> For the server, wich are the differences between both client configurations (single-JVM vs 10 JVMs)?
- - Does a new TCP connection request from the same JVM involve less work if one is already established?
If not, and if each virtual client uses its own TCP connection, there is no cheating, and I don't need to worry about this level of bias.
- - Does an HTTP request that comes over an established TCP socket require less server work than an HTTP request that reqests a new TCP socket?
Probably (in the second case the server has to accept the TCP request and probably pool it, and assign a reader thread, etc...). So I do need to worry about this bias. One way to avoid it is to manage to have the virtual clients not using each other's HTTP connection.
And so on...
Is it possible to build a comprehensive list of the differences incurred by the single-JVM configuration?
Then for each of them, I can try to evaluate ways to alleviate the bias.
- If I managed to avoid or alleviate each and every bias, I would be back to a realistic simulation.
- If there remained only the biases that handicap the server (such as, the server crashes under a 15 clients load, whereas in reality it could sustain 25), then I could be conservative and announce "the server will handle 15 clients gracefully" to the salespeople that will establish the SLAs. I understand that I may never be able to prove that the server actually scales up to 25 concurrent clients, but as long as the conservative SLA matches the market target that will do.
- If I'm left with biases that do favor the server, then I can't rely on the test platform and I'll reluctantly but resignedly try to have a more realistic platform funded (the more likely outcome is to be asked to provide probabilities and disclaimers in the test reports).
Thanks for your help so far, and please bear with my stubborn but polite request to try to identify further the differences ad causes.
J.

Getting kicked off of VNC connection when logging into server

We have noticed that when we log into the VNC server, and sign into the console of the server, that we get kicked off of the VNC connection. If we wait a few seconds then connect again we get the desktop of the server.
What is causing this? I use JollysFastVNC 0.98.50 (928701) and a coworker of mine uses ChickenoftheVNC, both are on Macs. It is very annoying. I do like that when I'm done and I log off of the console that it also logs me out of the VNC connection. But kicking me out for logging in is absurd.
Thanks,
Ben
PS. The server is Mac OS X 10.6.1 on a Mac Mini last generation, since they just came out with a new one.

I linked to the free client. That is what runs on the computer that you you turn on in System Preferences --> Sharing, so you are going to want to install that on the server, not the machine you are connecting from. If you installed it on both it doesn't matter—it was there anyway as part of the OS. It is built into the OS, but a reinstall can fix problems and makes sure you have the latest version. The ARD application is what you would use to connect with from the machine you are sitting in front of. That is what costs money. Apple calling the software "client" can be confusing.
Have you turned on the VNC option under either Screen Sharing or Remote Management. You will need that to connect with a third party VNC app like JollysFastVNC or Tight. If you don't turn that on then the built in Screen Sharing app should just work (accessible from Safari or the Connect to Server dialog in finder by typing vnc://ipofserver)
It is hard to say if this is a SL bug, or a problem on your network since you only have one machine to test. You could try running Vine Server on your server. You will want to change it's port to something else like 5901, or at least turn off Screen Sharing so it doesn't conflict ports. If you change the port you would connect by typing vnc://ipofserver:5901
In Vine be sure to use System Server (under Server menu) to keep vine running all the time, even after a reboot.

Connectivity issues between Cisco 2901 and Cisco SG300-52

Hello,
I am having some serious connectivity issues between the hosts in my LAN.
My LAN is based on a Cisco 2901 router and a Cisco SG300-52 port switch.
The issue that has been happening is that connections between hosts on the LAN (remote desktop, extended ping, etc) is very unstable, at some point I can see a 35% lost packets on an extended ping. This happens at any time of the day and from any host.
All hosts are on the same Vlan(default Vlan) and on the same subnet. Some hosts have fixed IP addresses (servers and network equipment) and others obtain their IP address trough a DHCP reservation established on the router (reserved with the MAC address of every host).
I can provide further details if needed, because this issue is very serious and I would really appreciate any insight or support.
Many thanks in advanced.
Sair Amer
EDIT: After doing every test we could think of, we finally found the reason behind this problem.
It turns out that the switch has problems handling communications between clients at different speeds, because most of the hosts connected were working at 100 Mbps but the servers were working at 1000 Mbps (and the communication between host and servers wasn't stable).
After manually setting the speed on all ports to 100 Mbps the problems have stopped.
Many thanks for you help on this issue.

Client Log file

Is there a method do turn on logging on GW 12.0.2 Client activity on a PC?
We have a few users that keep getting random 30-50 second Pause where GroupWise says "Mailbox unavailable" then all is ok again.
This happens on these few users 1 or 3 times a day.
POA Logs do not show any indication of an issue.
PC event logs also do not show any issues.
Just wondering if the GW 12.0.2 Client has requested something and is waiting for a response.

Laura

Hi David
Open up your poa web console, go to log files, select all and enter 8911
as the search criteria. The resultant list will show you if you are
experiencing this error. It affects communication between your clients
and the poa. If you are experiencing this error then you do need the
udpslap statement in your startup file.
Let us know how it goes.

Hi,
There can be many reasons why the Login is "up the creek".
Any break in the network at your end whilst logged in will cause an issue.
A sort of discrepancy between what iChat thinks the state should be and what the server thinks.
If they don't agree the server will refuse to accept.
A Crash at the server end which does not log you out properly will also do it.
Any file at any time can be come corrupted.
Luckily with the iChat .plists they are recreated if removed with an iChat Restart.
If it were AIM you can also get your Account Suspended and this will not log you in.
(It tends to happen from Chat rooms where people notify AIM about bad behaviour (as they see it) and you have to apply to get Un-suspended).
Most of the big IM services use multiple servers.
Sometimes these go out of Sync.
In the case of AIM this happens when they remove Old unused Screen Names from people's Buddy List prior to making them available for re-registration. I am not sure if this happens at Google.
You seem to be talking about an account that has worked at Work and having new computer at home.
As I mentioned the Priority thing you have not said that it has coincided with the new computer logging in (this will kick the work Computer out of Google whether you are logged in on the Web Mail page or in iChat)
IN addition to that iChat stays partially logged in for Off Line IMs
This is done in the background by a support app called iChatAgent
If your Computer is ON but ichat is not started people can still send you Messages.
Instead of saving these on the server until you login iChat will start up.
Depending if the home Mac is effecting the Work Login it may be holding sway over your Login.
Using your girlfriend's login may have booted her Off Line where she normally uses the name/login.
The AIM Side can be specifically set to allow Multiple Logins and therefore NOT allow them. If this happens you get a warning and messages to do something about it.
You do not get these in any Jabber or Google Login as the Priority setting is supposed to take care of it.
If the Login works at the Web Mail Login and on one computer then the .plist on the work computer is the most likely issue.
There is a small chance that a Corrupt Buddy Pic (Home Folder/Library/Caches/com.apple.iChat/Pictures) may be the cause.
Set this folder to icon view and also use the Finder's View Menu > Show View Options and select icon view.
This should show all pics as their icon.
Check that all display properly.
At this point I would try a COMBO version update install of the last Update you did over what you have.
This often corrects hard to trace things

How can I make a server differ between two or more clients?

How can I make a server differ between two or more clients?
The clients can connect and talk to the server fine, but how can I make the server talk to one, two or all clients? i.e. what would be a good way to implement this?
Currently, the server listens for connections like this:
while (listening) {
try {
new ServerThread(this, serverSocket.accept()).start();
I guess one way would be to add the ServerThreads to a Hashtable with the client ID as key, and then get the ServerThread with the proper client ID, but this seems unnecessary complicated. Any ideas?

Complicated was perhaps the wrong word, I should have
written something like it doesn't "feel" right. Or is
this a common and good way to solve communication
between a server and multiple clients?Thats pretty much how I do it. I normally use an array or ArrayList of Sockets instead of HashTable, with [0] being the first player etc.... Then you can communicate with exactly who you want. If you want to send bytes to all of them, just send the same thing to each socket individually (or is there a better way to do this?).
