IChat Hangs - "Failed to connect to iChatAgent"

ok this just started today. put the macbook to sleep and when i woke it up a few hours later, iChat won't launch. it bounces for a while (~1-2 minutes) then the whole machine locks up until ~4 minutes later a dialog shows up from iChat with the message "Failed to connect to iChatAgent." when i click OK iChat closes and the computer resumes what it was doing.
any ideas?
i have rebooted from the leopard disk and ran repair disk (no problems found) and repair permissions (some problems found and corrected). after that did not work i reinstalled iChat from the Leopard disk.

deleted preferences files and ichat works again.

Ichat hangs at connection, then dumps

Hey there,
so my ichat seems to hang just after connecting, i get an error that looks somthing like this:
Audio channel info: local machine using x.x.x.x:16402, expecting remote machine to send to 192.168.1.15:16402
Video channel info: local machine using x.x.x.x:16402, expecting remote machine to send to 192.168.1.15:16402
Seems like a reletively new development. I would say it's a router NAT firewall issue, but Ichat works on 2 out of 3 apple test servers. appleu3test02 never seems to work. although the other two work fine.....
also cant seem to connect with people i have in the past....hmmmmmmm.....
very interesting......this is common across all machines on my network.....in the past when i've had issues..if neccisary..I've simply disabled all my firewalls, as a troublehsooting tech, and then find any ports that need opening, but thats not the case here,,,,doesnt seem to help at all....
I mean, if 2 of the apple test servers work, but one doesnt, nor can I connect to some other people, whom I can text chat with, but not video....what is really going on here? It doesnt seem like a local issue?
ponder ponder.....oh ichat.......always an adventure with you.....
I love ichat...by far the best quality I have seen in any video chat.....
but I'm needing it to be far more stable then it is......
thanks for any help anyone might have....!!!!

Hi,
This log means you were connected (Even if you didn't see or hear them).
It can mean the other end dropped out of the connection without a formal iChat diconnection - hence the error message.
It is normally caused by a protection feature on one end.
It can be due to a Block on Internet Pings - iChat send one.
More likely it is due to a protection feature such as DoS protection or SPI filter
These tend to cut in more now that iChat 4 sends all the Video and Audio data on one port (when nothing else has changed)
So it is more likely your Buddies end than yours which will explain why the test account work.

Mail Fails To Connect In My Office Network, Works on Reboot

This is baffling me and my network admin:
Mail fails to connect to any of my accounts at work. But it recovers if I reboot my machine.
Here is what happens:
- Mail works just fine at home. Connects to gmail, iCloud, and a 3rd party email account no problems.
- I get to the office
- I log in to the office WiFi with my password - for this I have to open a browser window, and enter my credentials.
(I kind of assume that this is the problem ^^)
- All my internet connections work fine, I can use the browser to access Gmail etc
- Mail refuses to connect to any of my email servers, and all accounts go offline
- Connection Doctor says "Mail can connect to the internet" but all individual connections are red, not reachable. I checked "detail" too - its empty.
Then I reboot my Mac, and after that everything's happy. Mail connects to my accounts normally, and Connection Doctor marks all as green.
Since it works on reboot, we can rule out network problems like closed ports etc. So the only thing I can think of is that Mail initially tries to connect as soon as I am on WiFi, then hangs (because I am not logged in yet), and somehow this hang is of a kind that does not recover (I've left it on for hours at a time, no difference, it never recovers).
Anyone have any ideas about this? Is there some way I can restart networking daemons to kill the hung connections. Or any other way I can diagnose this?

A captive portal, which is what you have, can work in any of at least three ways: by HTTP redirection, IP redirection, or DNS poisoning. I'm guessing that yours is the last type. In that case, a TTL of zero should be used. If the TTL is non-zero, then Internet applications may not work until the DNS cache is flushed. That happens when you reboot.
You should discuss the possibility with your network admin. If the network configuration isn't going to be changed, you may be able to avoid the need to reboot by flushing the DNS cache manually, as described in the article linked below:

PING[ARC1]: Heartbeat failed to connect to standby 'standby_nespets1'.12514

Hi,
I have a 4 node 10.2.0.3.0 RAC on RHEL4, OCR files on OCFS2 and DB Files on ASM. Due to some issues, we have temporarily shut down 3 nodes of the cluster. we also have 2 physical standby databases for it. Today we had the following error in the alert log:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
+PING[ARC1]: Heartbeat failed to connect to standby 'ONCRSDB'. Error is 12514.+
and after that, the whole server hanged. This happened 3 times and I had to cold reboot the server to access the prompt, then I decided to disable the log_archive_dest for that standby db. The standby dbs and primary db can tnsping each other.
Does anyone have any idea about that?

Start simply,analyze the listener error message:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action:
- Wait a moment and try to connect a second time.
- Check which services are currently known by the listener by executing: lsnrctl services <listener name>
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.
- Check for an event in the listener.log file.

IChat crashing my internet connection?

Hi,
This is a pretty strange one. If I try to do an audio or a video chat, I get the typical "Failed to respond" message. More than that, though, my internet connection appears to break for about 45 seconds after this happens. I can't connect to any websites, Skype logs out, any downloads pause, etc. For whatever reason, trying to initiate an audio or video conference makes the internet connection stop working temporarily. Am I missing something?

A final chapter;
After some reading, I came upon this link " http://www.ralphjohnsuk.dsl.pipex.com/page4.html#_text " and ... the white box part at the bottom of the page helped so very much ( Thank you ) . Now the MacBook Pro can audio and video chat with the Apple test sites you had noted. The thing is, now I can't see her being online from my PowerBook ( using iChat 2.x) while connected to the same router ( neither can she see me being online) . I really am not worried about this, since when travelling abroad, I would be connected to the internet through an airport wireless anyway (ie. we would be using two different routers for connecting to the internet, at least her router works for her side of the connection) . Do you think I could be reassure that when I am on the other side of the water ( USA ) I then could see her being signed on in my iChat . Thank you again for all your time and help.

Having problems with shut-down of server after I open a socket connection (which fails to connect)

Basically here is an example servlet - new iPlanet 4.1sp9 instance with an empty classpath (apart from the servlet class) - running solaris v5.6 (Generic_111446-02)
If you run the servlet and then try to shut-down iPlanet it hangs. If you remove the 'new Socket(...' line then it's fine. Any ideas why a failed socket connection stops the server restarting? (Connecting to a listening port does not exhibit this behavior).

Rob:
it's due to JVM signal handler that catches the stop signal and you're forced to use a kill -9 -
Note that the stop script of a fresh install of iWS 4.1SP9 should contain the kill -9 - as a workaround for this known JVM issue.

Failed to connect Error - Need Help, Please

I installed , created the simple "Hello" program and it ran fine on the simulator.
Then, I click the run OTA and now I'm in deep yogurt!
I get the message:
*** Error ***
Failed to connect to device 0!
Reason:
Emulator 0 terminated while waiting for it to register!
BUILD SUCCESSFUL (total time: 4 seconds)
I just want to restore things to what they were before I selected Run OTA. I've been reading for the past 3 hours and haven't found out to restore. I even deleted and re-installed but, still get the same meassge (probably some saved java pref file...). Anyway, HOW TO RESTORE to a virgin setup????
Thanks

Remote app on ipod fails to connect to itunes 10

After upgrading to iTunes 10, my remote app on the ipod touch 4G fails to connect. I've reauthorized, which times out most times, but eventually when it works, it only continues to connect to iTunes until I close and restart the program. I've disabled all firewalls and still have the issue. iTunes 10/iPod Touch 4G/iOS 4.1/ancient remote.app do not play well together.
Anyone else unable to get the remote app working reliably with this combination?

Hello all,
I would like to get more details from people who are still having trouble getting Remote 2.0.1 to connect. If you are unable to connect, please email me <[email protected]> with the following information:
- A detailed description of the specific issue you are seeing.
- What OS is on the host computer? (the one with iTunes on it)
- What OS is on the affected iOS device(s)?
- A description of your network topology. Please be as detailed as you can, including hardware and firmware versions, if possible. Also please explain how everything is connected.
- Is the base station running default settings, or do you have any non-standard settings enabled? If so, please elaborate.
- Do you have the built-in firewall enabled on the host computer?
- Do you have any other firewall or Internet protection (anti-virus, etc) installed on the host computer?
- Were you able to connect with versions of Remote prior to 2.0?
- If you have multiple computers, can you get Remote to connect to any of them?
- Does Home Sharing work between computers on your network?
- Do you see any messages in Console (in Applications/Utilities) on the host computer that seem to coincide with the connection failures?
Thanks,
Roy

My iphone 5 won't make a call when i fail to connect to the internet via 3g

My iphone 5 won't call when i fail to connect to the internet via 3g.
At work i dont have wifi i have 3g, if i launch say the sky go app,or the iplayer, sometimes they work and everything is fine...sometimes they wont load as 3g for whatever reason cant get a connection at that particular time........ if i then try and make a call the call will fail. I've experimented 25 + times and this is definately the cause.
(note: when the 3g connection does work, the phone has absolutely no problem calling people)
Anyone had this problem?
Even better has anyone got a solution?
Thanks,
Nick.

Are you sure that the carrier's signal is strong where you are having this problem? Certain building structures and locations have poor cellular signal strength and this often results in the "No Service" indication. Are other users able to get service in the same locations where you have problems?

On Windows 2012 Terminal Server Outlook fails to connect to Exchange 2013

I have a new install of Windows 2012.  I have two physical servers. One is a W2012 std Domain Controller ("DC"). The Second is configured as W2012 HyperV  ("HV"). Under HV I have
two VMs. One VM is W2012/Exchange 2013 ("ExchVM) and the other is W2012/Terminal Server ("VMTS"). All systems are behind a firewall appliance. Exchange is working via Outlook and OWA internally and externally. The self
created SSL must be installed manually on external machines since it comes up as an untrusted certificate. Once installed remote outlook works and OWA works. I have configured the terminal server and I am able
to login remotely as various users under my "TS group". The problem is when ever I attempt to open Outlook for the 1st time, it fails to connect to the exchange server.   (Open Outlook 2013, click next
on the splash screen, "Yes" Add an Email Account splash screen, click next, Auto Account screen populates NAME and Email Address correctly, click next, Searching for mail server settings..., check on establishing network connection, check on searching
for alias@ domain, then fails the logging on to the mail server) The error reads: "Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The
connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."   I am connected in RDS from offsite, and from the RD session I can access shared folders on ExchVM and DC. I have
tried have verified the server Exchange server name is correct via "Get=ClientAccessServer" command. I have also tried to use the guid via "Get-Mailbox
ALIAS | fl name, exchangeguid. Keep in mind all desktop users on the network are connecting to Outlook without issue.
I would appreciate any thoughts on solving this issue.

Hi,
According to your workaround, it seems that the Outlook Anywhere configuration in Outlook client is not correct when using the Autodiscover service.
Once you connected to Exchange server by manually settings, please run Test E-mail AutoConfiguration tool in external Outlook client to check the autodiscover service:
open Outlook - press CTRL key - right click on the Outlook icon from right bottom corner taskbar - Test Email AutoConfiguration. Put your email address - uncheck use guessmart and secure guessmart authentication - click Test to check your Autodiscover service.
Please check the Log tab and confirm whether the Autodiscover service is connected successfully. Also confirm if the connection issue happens to all external users when they open Outlook for the 1st time. In Exchange server, please make sure
autodiscover.domain.com has been included in your Exchange certificate which is assigned with IIS service.

Fingerprint reader not working in IE and saying failed to connect to sensor

Hi all,
I bought a Qosmio x500 10t a couple of months back. For the first couple of weeks i had no probs using the fingerprint reader to log in to windows and to log in to websites in Internet exploer.
All of a sudden it would not work on any website stored. The green banner showed accross the top of site and asked to swipe finger but nothing happened when I swiped. I rebooted and it worked again but not for long before failing. This time a reboot didnt work so i deleted my finger prints and websites and started from scratch. That worked for a couple of attempts before probs started again. And on trying to get into Fingerprint utility it says failure to connect to sensor. So, I did a system restore. It worked for a couple of times again and then same probs. So I found the updated utility software, uninstalled the old and put on the new. Same again, worked for a couple of times then failed.
I could not find anything stuck in the registry but to be on the safe side i did a full system clean back to factory setup using backup discs. Hey presto i thought it had worked. Everything going ok for first 24hrs and then same problems start to occur. Only this time it is also prompting me to enroll fingerprints even though i already have. And when i try to get into the utilioty it says failed to read sensor again.
The fingerprint log on to windows always works as long as i dont close the fingerprint utility down before shutting down. If i do exit the utilty i cant reopen it as it just says failed to connect to sensor. And then i have to unistall and reinstall the utility software. Aty the moment it occasionally works on websites stored but most of the time it doesnt do anything.
Please help. Do I need to send laptop back to Toshiba??

Hi,
*I got a solution* for the problem that the fingerprint sensor "suddenly" does not work any more.
When starting the Toshiba Fingerprint Utility, it says "failed to connect to fingerprint sensor".
Is it possible that just before it stopped working there was a new firewall installed, or firewall settings had been changed?
*In my case, the problem was solved by changing my firewall settings* (Windows 7 Firewall Control) to ALLOW all traffic for
the Authentec Fingerprint Sensor Service (AFSS). It is the file "AtService.exe" in C:\Program files
The reason is simple:
The Toshiba Fingerprint utility communicates with the fingerprint sensor service via TCP/IP.
Therefore, any firewall that blocks traffic on the local computer will block the communication.
*After changing my firewall settings, fingerprint sensor works* on my R700 flawlessly now.

Error sending emails to Internet: Failed to connect. Winsock error code: 10051

Our exchange 2013 CU2 (CAS+MBX, Win2012) was sending emails to Internet using another server (a kerio email server) and outbound internet email was working as expected.
We have now removed the Kerio server, I also removed the kerio_Send_Connector I was using to send emails to internet and I also changed the email domain in Exchange to be authoritative. I created a new Internet send connector with default values, but the same
bad behavior is present.
Our Exchange 2013 receives emails internally and externally with no problems. The problems are sending emails to Internet. I am suspecting something in the firewall but i need to do some more research.
If from the same Exchange server I telnet to an Internet email host:25 I do get the smtp banner but as soon as I start typing HELO/EHLO I get disconnected and errors are logged.
Errors when sending emails to any emails address (this is from an email sent to google, all others are the same):
Remote Server at aspmx3.googlemail.com (74.125.136.26) returned '400 4.4.7 Message delayed'
7/1/14 9:52:44 a. m. - Remote Server at aspmx3.googlemail.com (74.125.136.26) returned '441 4.4.1 Error encountered while communicating with primary target IP address: "Failed to connect. Winsock error code: 10051, Win32 error code: 10051." Attempted
failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was 74.125.136.26:25'
I cannot find any references from such Winsock error that are related to Exchange 2013.
So far all email is being queued at the Exchange Server 2013. I am afraid to install CU3 and make things worse.
Thanks for your comments.

Just check if the receive connector settings are set to fine
check the send connector properties and see whether it is set to use DNS to route emails through external DNS/Internal DNS or smart host .
Do a telnet to external domain like hotmail,yahoo and see at what transaction you are getting an error
Enable verbose logging, restart the transport service and check if you get the same error in the verbose logs as well
Get in touch with the ISP and see if the port 25 for Outbound SMTP is opened.
YOu can check if SMTP Proxy is enabled in the firewall. If so disable the SMTP proxy in the firewall and check.
Good Luck!!
