Connection time-out but then immediately after, no problem

For some reason, the first time I use pacman (after not having used it in a while), the connection times out, but when I Ctrl+C and then do the exact same thing, it starts working.
Any ideas why?

I'm using SSH to connect to the server where this problem is happening, indicating that the LAN connection works. Before invoking pacman I've tried pinging google.com, which works flawlessly.
The problem is still there, I just tried it.
EDIT: This actually happens with wget too:

Connection times out (but only on Leopard)

I run an iMac (one year old) and connect to the web via Airport. I'm having consistent problems with the connection timing out after 2 or 3 minutes; it's really frustrating and is pretty constant. It's not an Airport problem because I can connect my old Dell quite solidly ( which I'm typing this one) and my iPod Touch without any problems. It started about three months ago
So it's only the iMac affected. Any ideas? I'm not a techie and I'm new to Macs

I'm getting these time-outs as well. Computer is fine for the first few minutes, then when I try to go to a new URL (Safari) it appears I'm not connected anymore. When I quit and relaunch Safari, it comes back up. At first I thought it was a router issue but now I don't think so, because when I ran Network Diagnostics, it said I'm connected.

SMTP connection times out on the MMP after a hung dirsync.

The dirsync ran all night, at 8am we found that SMTP to the MMP was no longer working. We restarted it, it still would not take connections. We've shut down all Iplanet systems on the MMP and looked for the lock files, deleted those we found and restarted. Still not working. Any insight would be appreacitated.

Ray,
First off I think you're talking about an MTA not MMP. Two different beasts. You also do not mention what version of iMS you are using. Try the following:
cd msg-<instance>
./imsimta shutdown
./imsimta cleandb
./imsimta startup
NOTE -- I've no idea how large your environment is but if you change local.ugldapbinddn and local.ugldapbindcred to that of your Directory Manager and password you'll see dramatic performance increase on the LDAP side and thus dirsync will finish faster.

Error occuring during manual login after idle connection time out

Hi,
I am using a PowerBuilder (v11.1) application to access Crystal Reports (BOXI Enterprise v 3.1) using Opendocument. The app server is Apache Tomcat. We have implemented SSO using Vintela and at present we have set idle connection time out to 1 hr. The problem I am facing is listed below:
The SSO Authentication works fine for accessing these reports. But when we try to run crystal reports after not using it for more than 2 hours system prompts us for login. I understand that we are getting login prompt because connection was idle for more than 1 hour but when we manually enter our login credentials it gives us an error 'An error has occured. An error occured while trying to view the document'.
However after getting the above error if we again try to run the report, it works fine.
Please can anyone provide us with some insight as to why this behaviour could be occurring. Any help would be much appreciated.

->in application connection time out is set to zero
Are you sure? There are two different can timeouts you can experience: connection timeouts and command timeouts. The link posted by Praveen is about command timeouts. The default for the connection timeout is 15 seconds and the command timeout is 30 seconds.
It is very reasonable to set the command timeout to 0, which means that wait forever. Waiting forever is less reasonable for the connection timeout. But when I think of it, I am not sure that 0 means "forever" for the connection timeout. So if you
have set it to zero, maybe that is your problem.
Else, I would suspect a network problem.

Take each of the following steps that you haven't already tried, until the problem is resolved. Some of these steps are only possible if you have control over the wireless router.
Step 1
Turn Wi-Fi off and back on.
Step 2
Restart the router and the computer. Many problems are solved that way.
Step 3
Change the name of the wireless network, if applicable, to eliminate any characters other than letters and digits. You do that on your router via its web page, if it's not an Apple device, or via AirPort Utility, if it is an Apple device.
Step 4
Run the Network Diagnostics assistant.
Step 5
In OS X 10.8.4 or later, run Wireless Diagnostics and fix the issues listed in the Summary, if any.
Step 6
Back up all data before proceeding.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.
Step 7
You may need to change other settings on the router. See the guidelines linked below:
Recommended settings for Wi-Fi routers and access points
Potential sources of interference
Step 8
Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
Step 9
Reset the System Management Controller (SMC).

I am using itunes 10.5. Update didnt work on last software but restore did work. Help

After two days of attempts, Google & Apple searches, one Apple post stated to turn off all firewalls and virus software and keep trying since there were 6 gazillion people trying to update. I have Windows 7 & Kaspersky and had to diable every single safety feature in Kaspersky as well as Firewalls and it finally allowed the download and update attempt.
Glancing at the forum, there appears to be numerous other problems with missing pictures, text problems etc after the IOS5 download but fortuneately, everything seems ok so far. Good luck, it is frustrating! Hattie47

Don't DL Flash from web sites. If you have Adobe Flash installed it should be in System Preferences and you can find the latest version and download from there.

HT4628 my powerbook g4 os x 10.5.8 leopard is showing-Connection time out while connecting to the wifi.however it showing all available wifi connections around but not connecting it..however ethernet is working

Problem while connecting with Wi-Fi,
When i am connecting my powerbook g4 leopard to any Wi-fi connection it showing -Connection time out, however Ethernet is working .I have updated all softwares but still same problem.

It's possible that either the internal AirPort Extreme card or the antenna is faulty or has failed.
One last thing to try before going with another Wi-Fi solutions is to the following:
Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)
3. Run the Disk Utility to repair Disk Permissions.
Restart or log out then back in.
4. Turn off the Mac OS X Firewall
System Preferences > Sharing > Firewall
Click the "Stop" button.
5. Create a New User Account
System Preferences > Accounts
Click "+" to add a new account
Log off, then log back on with the new user account.
Try connecting with the AirPort.
If none of these help resolve the issue, you may want to consider getting a USB wireless adapter to replace both the internal card and antenna. One such vendor of these adapters is Other World Computing (OWC).

What is going on?
It's being rewritten by dhclient or dhcpcd, most likely. You can put your settings in /etc/resolv.conf.head to get them to stick, because when dhcpcd rewrites resolv.conf it includes the contents of resolv.conf.head at the start of the file. You can also tell dhcpcd not to rewrite resolv.conf by adding "nohook resolv.conf" to /etc/dhcpcd.conf. I assume you can do the same with dhclient, but I don't know how off the top of my head and I'm writing this from a train with very patchy coverage on my phone so I'm having trouble getting the page to load.
The culprit may also be pppd, if you're running ppp connections off this machine. You can disable usepeerdns in the config for that ppp peer.

Cannot connect to WIFI - 'connection time out occured' but also says 'no ip address'

Hi,
I've searched the web and found endless issues with the wifi router / etc of the Imac Lion system. On the same wifi network we have a mac book (leopard I think), a pc laptop (which I am using now) and 2 phones + my brand new Imac with Lion osx. The first 4 items all connect with no problems.
I tried some of the sollutions here but it even made it worse as I now not have any connection at all!
http://support.apple.com/kb/HT4628
When I try to connect trhough systems preferences/network I get the message that my password is incorrect and that there is no IP address. Password is definitely correct. When I try to connect from the symbol in the right top corner - I get the message 'connection time out occured'
I am a bit of a Mac dummy ... any help is really appreciated.
Thanks

If I choose security 'WPA Personal' i get the message: connection time out
If I choose security 'WPA2 Personal' or 'WEP' i get the message@ no network found
hmmmm any suggestions? Thanks so much

Transaction on Oracle 9i data source connection times out before JTA transaction

Hello,
I have a MDB with a long-running transaction (3600 second timeout).
In the MDB, I make a call to another EJB that has its transaction
attribute set to NotSupported (I do this because I need
non-transactional semantics in the called method).
If the EJB call take more than about a minute to complete, then I get a
datasource error when using the data source in the MDB after the return
(see error at bottom). However, if the call completes quickly, then I do
not get this error. It seems like the datasource connection somehow
times out, but I don't see where I can change this timeout.
pseudocode:
// timeout set to 3600 seconds
transactional MDB onMessage() {
// receive connection from Oracle BEA driver
// myEJB performLongOperation has transaction attribute
// set to NotSupported
String result = myEJB.performLongOperation();
// use connection from Oracle BEA driver
If the performLongOperation takes more than about a minute, then I get
the following error when using the connection after the operation:
Caused by: java.sql.SQLException: XA error: XAER_NOTA : The XID is not
valid start() failed on resource 'Oracle IDENT Connection Pool':

Thanks for the reply.
I don't have contract customer support access with BEA, and thus I can't
download the patch. Is there any other workaround for this?
Thanks

Upgrading iOS 4.0 to 4.1 (Connection time out error)

Hello any help will be highly appreciated..
I currently have a 3rd gen iPod Touch 32gb, with iOS 4.0.2 installed and working perfectly. I am now pestered to download and update to the newest version 4.1 every time I sync my iPod, which I have no problem doing..
Problem is every time I agree to download this update iTunes downloads the update then when it has just finished downloading (remains in the "downloads" in itunes folder) appears that it is processing the download, after about 4 minutes of it finsihing downloading and appearing to be processing it gives me an error saying there is a connection time out issue, to check my internet connection and try again.
I have tried at least 1 dozen,or more times to do this. It has done the same thing every time.
It won't let me restore my iPod because when i try to do so it asks me to "Update and Restore" which it cant update! so its pretty frustrating.
The iPod works fine no problems, it just comes to when trying to download this update.
Is there anything I can do? Would I be able to try and update it on another computer?
Thank you for any assistance, im just sick of seeing the "a new ipod update is a vailable, download now?" pop-up every time I plug in the iPod.

Hello!
Been encountering the same problem for two days, drove me crazy! Tried everything, including disabling the firewall and antivirus but nothing worked, so here is what worked with me:
*If you use Internet Explorer, do the following:*
*First close iTunes then go to Internet Explorer > Tools > Internet Options > Advanced Tab and then scroll until you get to the ''Security'' section, uncheck the box that says: Check for server certificate revocation* and now launch iTunes and try again.* Hope this works for you as well!

Java Socket Connection Time out

Goal*
I want to check host/port availability of computers in our network (~100 computers) .. Just check if host is alive and if it has port 445 opened. I want to do this somehow in parallel, so the code execution is as quick as possible.
My implementation*
I do this by creating socket connection to the host. Something like this:
        Socket s = null;
        try {
            s = new Socket();
            InetSocketAddress socketAddress = new InetSocketAddress(ipAddress, 445);
            s.connect(socketAddress, 3000);
            if (s.isConnected()) {
                // do something
        } catch (ConnectException ex) {
            //exception thrown
        } catch (IOException ex1) {
            //exception thrown
        } finally {
            try {
                // close socket
                s.close();
            } catch (IOException ex) {
                Logger.getLogger(ComputerModel.class.getName()).log(Level.SEVERE, null, ex);
        }This code is executed in a loop, where a separate thread is created for every iteration = ~100 separate threads.
Problem:*
1.
It seems to me, that first ~10-15 connections are created ok, but then my code reaches 'IOException' catch block for every subsequent itteration and ex.getMessage() returns "connection time out" (I try to use different timeout values in the 2nd parameter. Values from 3000 up to 20000).
Is it valid to create 100 separate threads in a loop? Can't I make my NIC to bussy with this ??? What is the maximum ammount of threads, I can create? I did not use threads before, so I have no idea, if max values are near to 10, 100, 1000, or 10000 ..
2.
After my code is executed, I enter 'netstat -an' command in my command line and I get bunch of connections, which report status of SYN_SENT for several connections.
TCP 10.20.11.140:4557 10.30.11.119:445 SYN_SENT
TCP 10.20.11.140:4558 10.30.11.176:445 SYN_SENT

TCP 10.20.11.140:4561 10.30.11.171:445 SYN_SENT
TCP 10.20.11.140:4562 10.30.11.143:445 SYN_SENT
TCP 10.20.11.140:4563 10.30.12.12:445 SYN_SENT

TCP 10.20.11.140:4565 10.30.12.21:445 SYN_SENT
TCP 10.20.11.140:4566 10.30.11.150:445 SYN_SENT
I also feel, that my computer network response (e.g. firefox browsing) is a bit slower ..
How shall I handle this problem properly?
Thx in advance,
Juraj

there will never be a SYN-ACK.
After a few minutes the TCP stack will time out the connection attempt.Yes, I was rather commenting on why his hosts aren't answering. I thought that his case was that all of them should answer :)Akkurat. I was answering more for clarification.
Someone who does not know your posting history could easily assume you meant
it was a mystery why netstat was showing SYN_SENT.
And I figured it would not harm to hint that one possible reason would be that those machines are powered off (no host).
