Connection timeout

How do I set the system property java.io.connectiontimeout ?
My program is trying to connect to a server that is down .
public class Test {
System.setProperty("java.io.connectiontimeout","20") (Assumption timeout is in seconds).
Socket mySocket = new Socket("host","port");
I am using jdk1.3.1
I want my program to timeout if it is unable to connected to the server after 20 secs. My programs hangs if the server is down.

The problem is resolved. I tried to set the property
java.io.connectiontimeout instead of
java.net.connectiontimeout.Hm, that method doesnt seem to work for me. I set java.net.connectiontimeout as well as java.net.PlainSocketImpl.preferredConnectionTimeout to value 1 (for lan testing), but still I have to wait for about 20 seconds for the time-out exception.
Any suggestions?
Are there any docs on when and how those properties are actually considered by Socket?
Thanks,
unpaid

Is there a risk of setting a console connection timeout and what is the recommended setting?

Hi Henrik
depend on what you need or what your security policy says for my lab gear i use 60 minutes. because i know how can access this. if you have gear outside in insecure space set it to a minimum or disable the console. everybody how can access your gear can break in. simple restart and boot w/o config. and you are in.
it realy depends how secure is your space and how much security you need.
and than the settings for policy have to match, what sec do you have if your console login and logout is secure. but when you restart you can simple break in by starting w/o config and than load it.

I am getting a "connection timeout" message when trying to access my Airport Extreme with various laptops, Play Station 3 and Wii. My Airport Extreme is about a month old; it was working fine until about a week ago. Suddenly, the "timeout" is not allowing me to connect to my wireless network.

It could be that there's a new source of interference.
Use the advice in the second message of this thread to investigate the signal and noise levels that each client sees:

Why do I keep getting a "connection timeout" error on my macbook pro?

What seems to be on some kind of time schedule, my network connection times out. The message "a connection timeout occured" is displayed, rendering my attempts at re-connection useless. After hours of troubleshooting(my router included) and checking out other Mac forums, I have no solutions but to power cycle my router. This pretty much makes my MB useless unless using a wired internet connection outside of my home network. I've done tons of research online and have encountered hundreds of people with the same problem. My machine is a late 2011 Macbook Pro. PLEASE HELP

Time Capsule woes -- Connection timeouts and can't connect with one Macbook

This is my second Time Capsule. Here's the scenario:
I have a Netopia 3347 DSL modem. That feeds into the Time Capsule in bridge mode. There is a MacBook (metal case), iBook (yes, it's old), two iphones, a color printer and an iPad that can all connect to the Time Capsule just fine. The problem is my MacBook can't connect. The offending computer is a 2.2Ghz Intel Core 2 Duo running SL 10.6.6. This computer can connect to the Netopia just fine, so I know its internal Airport works. After several go arounds with Apple tech support, I'm still nowhere.
Here are the symptoms:
1. I can see the TC's network SSID in the airport pull down menu. If I select the TC, a popup appears and asks for a password. If I enter the password, I'll get a connection timeout error.
2. On the rare occasions where it does connect, I can't open a webpage. Network diagnostics has red dots for ISP Internet and Server
3. On the even rarer occasions where it does connect, and I can access a webpage, it's unbearably slow, and the no-surf problem reappears after a few seconds. The red dots on the Network Diagnostics reappear.
Apple tech support was not helpful. I've power cycled everything a million times (and that doesn't explain why other computers can connect.) I know it's not my computer, because it can connect to the Netopia just fine.
I am STUMPED.

Magnificent! Problem solved... Isn't there a "this solved my problem" button somewhere?? Thanks and thanks again!

Macbook pro keeps saying connection timeout, and it used to connect to the internet fine. what's up, why can't it find and automatically connect to the internet anymore???

Connection Timeout after updating to 10.6.6

Dear Friends
I've got Macbook Pro mid 2010, when I was on 10.6.5 there was no problem connecting to Wi-Fi but after the magic update, I always got "Connection Timeout". another thing to add, I can connect to any network via windows 7 I installed on my macbook.

My two cents is that I have had some type of network problem since install Snow Leopard. I even went back wiped drive and did clean install. Seems their is a problem but not sure if its multiple problems or just one. Safari seems to load pages at a crawl at times. I did several speed tests and found the WIFI connection noticeably slower (about half) compared to my Windows Vista computers running WIFI. Even though my MacBook has N version connection and the Vista ones G.
I have tried different DNS servers and nothing seems to help. The router is the second one I tried. I had a Linksys wrt54 then bought a Belkin F5d8236-4 and both have no effect on the problem. Even a different browser did not help. I have simply determined that Apple needs to fix something in Snow leopard.

My MacBook Pro persistently will not connect to my wireless router. The message "connection timeout" appears. What is a connection timeout and how can I fix?

Connection timeout on hotel wifi - only with MacBook8.1 (810.9) configd plug-in:8.1 (810.9)

I'm having a "Connection Timeout" issue while trying to connect to my hotel's WIFI.
I bought an ex-lease refurbished white MacBook (Build 12E55 - 2.4GHz, the last 2010 model I think) a couple of weeks ago. I bought it so I could use it while on vacation in Bali, Indonesia. I've got OS X 10..8.4 installed.
At home in Australia, this MacBook connected to my home WIFI with absolutely no issues at all.
Now that I'm in Bali, I'm surprised to find that every time I try to connect to the WIFI at the hotel (where I'm staying for a whole month), I get a "Connection Timeout" error. I'm surprised because my iPhone connects to the hotel WIFI with no problem at all, as does our two iPads and the Android phones that belong to other family members. It's only my MacBook that struggles, even though I get even better signal strength indicated on my MacBook compared to my other devices.
I can connect my MacBook to my iPhone hotspot fine, though I'd prefer to use the free hotel WIFI over my very small 3G data allowance.
So the problem isn't that my MacBook can't connect to any WIFI, because it did at home and it still can to my iPhone hotspot.
And the problem isn't with the router, because all other devices work flawlessly.
I've trawled many forums and articles trying to find a solution. Here's everything I've tried already, that I can remember. (Not in this order and not all at once.)
Rebooted MacBook (duh)
Sitting directly under the WIFI router. (It's not a signal strength issue.)
Set up new Network > Location. Deleted Ethernet and Bluetooth PAN so it's just WIFI in the list.
Renewed DHCP Lease countless times.
Tried manual TCP/IP variations. It doesn't help that I'm not sure what to put in the IPv4 Address field. I do know the Subnet Mask and Router IP from looking at my iPhone network info.
Tried using my MAC address as the DHCP Client ID. Also tried just using "1" or leaving it blank.
I don't know what an IPv6 is either.
Tried BootP and completely Manual setups but not really sure of the correct settings to try.
Tried using the DNS servers that I found on my iPhone network info for the hotel WIFI. (One of them is 8.8.8.8 which I think is Google's DNS thing?)
Tried checking Auto Proxy Discovery and Use Passive FTP Mode, since it was suggested as part of a solution in a forum thread.
Tried changing the MTU to a couple of other settings from an article I read. I think one was around 1453 and the other was 1494 or something close to that.
Tried resetting PRAM
Tried resetting SMC
Tried a variation on resetting SMC that involved pressing down the normal keys plus one extra, for 10 secs, since it worked for someone who was told to do that by an Apple Care person. (He didn't know why it worked and other forum posters thought it was supposed to have been a SMC reset.)
Checked the Network> Wi-Fi in System Information to see if the Channel is compatible. The router uses Channel 1 and my MacBook is capable of using Channel 1.
Checked my country profile. It's X1. I have no idea if that's good. All I know is that I'm in Indonesia not Australia and I'm having WIFI issues with this hotel network.
Checked the PHY Mode. Supported are 802.11 a/b/g/n. The hotel router uses 802.11n.
Made sure I was using WPA2 Personal.
Tried deleting all WIFI-related passwords in Keychain.
Tried deleting all Network-related preference files.
Tried removing all LaunchDaemons and LaunchAgents.
It's not a "lost WIFI connection when waking from sleep" issue but I tried turning off sleep anyway.
My husband even had the nerve to unplug the hotel router (small hotel, we're the only guests at the moment) for 10 minutes hoping it will reboot. But I don't know if that's the actual modem or just a WIFI repeater thing (sorry, can't remember the right terms). It didn't work anyway.
I've run out of options, other than just sucking it up and getting a big 3G data allowance since I'm here for a month.
If there is anything else I can try - perhaps working out how to set up my Network manually properly, please help me out. Here is everything in System Information that might help. I'll happily provide any other info.

Sorry. The topic title got mucked up when I tried to paste in my System Information. And I can't paste it in using my iPhone without it going haywire. I can provide any details you need.

Why do i keep getting the "internet connection timeout" error message?

i have been upgrading a few standard itunes albums to itunes plus versions through my 3g mobile broadband connection, while not exactly a fast process, it was working fine until i started to get a backlog of 3 or 4 albums which were waiting in a queue to be downloaded, now every time i do the "check for downloads" option i get the "internet connection timed out" error message...this has been going on for 2 days! am i right in suspecting the backlog of albums is too much for my 3g mobile broadband connection? this is really doing my head in, if any of you techies could help me, it'd be much appreciated...?

yes i have recently updated to itunes 8.2.1, but i am starting to think its apple's servers (i tried to download at my brothers house...different computer and connection...same connection timeout error), because it will still let me download an album, but not necessarily all of the tracks. when i questioned itunes customer services about the seemingly hit and miss state of affairs with downloading, they told me to wait 3 weeks before trying to download the tracks that were giving me the grief (2 tracks from an arctic monkeys album)...which kinda indicates they know there is a problem and are trying to fix it, why else would they say wait 3 wks??? they gave me 5 free music tracks too, which is handy.

A connection timeout occurred. I have been receiving this error when trying to connect to the open wifi connection at my university. My wifi works perfect when I am using it on my home network. I have tried all the suggestions in forums online no luck.

I am getting a connection timeout occurred message on my mid-2009 macbook pro I am running mountain lion 10.8.2 but problem occured before and after update. The message only happens when i attempt to connect to the wifi at my university. It works normal at my home. This error just started last semester out the blue. I have read many forums and non have helped ive reset my pram a few times, ive deleted all my networks including my home network out of my system preferences<network and all that extra stuff. if anyone has a clue please help me because one of my classes requires me to take in class test over the internet. Thanks for reading. If anyone can help PLEASE help ive been trying to fix for last few months.

From the menu bar, select
 ▹ System Preferences... ▹ Network
Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

I'm trying to connect to my home wifi with my imac gh5. After I enter the password it says connection timeout or password incorrect. I know there's no issue with the connection but I don't know what else to do. Does anyone know how to fix this problem?

What is the make & model of your home Wi-Fi router that you are attempting to connect your G5 iMac to? Which exact model of iMac do you have?
What wireless security type is your router using: WEP, WPA, or WPA2? If you temporarily disable wireless security, can the iMac connect to it now?

Could not join "wifi network name". A connection timeout occurred.

Mac Pro running 10.7.5.
Whenever the computes wakes from sleep or logs in, it no longer automatically connects to my wifi network. When I manually select the network for from the Wi-Fi status in the menu bar, I get the following message: Could not join "wifi network name". A connection timeout occurred.
Even though I get that message the machine joins the network with no other problems. I am led to believe that is is on the Mac Pro as my Macbook and iPad/iPhone join the network with no issues.
I have tried deleting and restoring the preferred network, and remember networks is checked. I have also restored my airport express base station.
Any suggestions?

Connection timeout with Apple WiFi devices

Ok, here's the scenario.
The important thing to remember is that all was working well, as happy as 'larry the lamb'. Being that I was running Snow Leopard on my MacBook Pro 8,3 while accessing the internet through my iPhone 4 using it's Personal Hotspot feature (with iOS 4.2.5/4.2.6 running on the iPhone 4). Internet thethering worked beautifully between the MacBook Pro & iPhone4 and all was well. Some time before this I had used the Time Capsule's WiFi for internet access with NO problems (when I had dedicated broadband), but then switched to using mobile tethering (personal hotspot feature).
I then upgraded to OS X Lion 10.7 (11A511) the day it was released and did this over a friends fast internet connection using cable ethernet connection for quicker speed. While I was doing this, I also downloaded the latest iOS update for my iPhone 4 being iOS 4.3.4 (8K2).
Then the problems started.. I have not been able to connect to the iPhone's Personal Hotspot, nor the Time Capsule's WiFi and neither the Airport Express unit (that plugs straight into the power socket). All three devices say 'connection timeout'. Resetting them either physically (reset button) or through the Airport Utility using an ethernet link (in the case of time capsule and airport express) make no difference.
I wish I never updated the iPhone iOS and previously put of updating it for the previous few updates because the tethering worked so well on it, therefore I would want to downgrade it to iOS 4.2.5/4.2.6 again (need to locate and re-download those two versions and accuire instructions - if anyone could help, would be very appreciated?).
Now this is the strange thing:- Although I cannot connect to the Apple Time Capsule, Apple Airport Express and iPhone Personal Hotspot (getting the 'connection timeout' error all the time), I am however able to connect to a non-Apple device Vodaphone 3G WiFi point. The Vodaphone 3G device is a 3G USB mobile dongle that is plugged into it's own dedicated small WiFi base station.
I am at a loss as to what is going on here?

I can totally understand your frustration and it ***** that you are having to experience it. I do know that for me yesterday the Apple.com page was down all day. I could connect to any other website, but not the Apple.com website. However, that doesn't solve your issue.
I would advise you to break down your issue by each component and then work to solving them one at a time. I would first look into getting your machine connected to the internet first. If you have no way of getting it connected to the internet without using the other devices you mentioned at your home network, then go to a friends or to a place where you can test your machine's ability to stay connected to the internet through a different network. This will allow you to rule out the posibility that the issue is isolated to your machine/OS. If you find yourself still having connectivity issues, then work on solving them before introducing your other devices to the problem.
Once and if you solve the issue with your machine I would then start looking into your home network and the devices you are using (i.e. Time Capsule, Airport, etc.) and be sure to check to see if you have the latest updates for them: http://support.apple.com/downloads/#airport
For my own network, I use a modem (ARRIS) and router (Linksys E2000) and have had no issues with any of my machines (running Lion) or any of my other devices (i.e. iPhones, iPods, printers, etc.) connecting to my Wi-Fi network. I do however have family and friends that are using the same devices as you, but are not having any issues. However, none of them are using their iPhone's HotSpot and neither myself or anyone else has updated to iOS 4.3.5.
I truly wish I could be me more of help, but the truth of the matter is when dealing with networks that deal with many different devices there are just so many variables that can be at play in regards to the issue, that you truly just have to take it one step at a time until you isolate the source of the issue at hand.

Can't connect via Airport -- "connection timeout" error, instead

I've got a MacBook Pro here, which was successfully connected online via Airport, under OS X 10.4.11.
Then I upgraded to Leopard (10.5), and the machine would no longer connect automatically to the router.
OK, I tried manually configuring the wireless connection, but no luck. So, I brought in an old iBook G4 running the same OS (10.5), and successfully linked it to the router, wirelessly, via Airport.
Copying the procedure that worked with the iBook -- to the MBPro -- did not help. Still getting a "connection timeout" error message.
So I performed a fresh install of 10.5 -- and I even DLed the Software Updates, including two that were supposed to improve Airport functionality -- and tried again. No luck.
Any suggestions?
TIA.

John,
I had the same problem when I upgraded from Tiger to Leopard in January. My memory is already rusty but try the following:
1. Go to System Preferences > Network pane. On the left pane, click on AirPort. In the right pane lower right, click Advanced button. Then on the AirPort tab, click on the name of your network and then the minus sign to remove it from the list.
2. Click Apply and quit System Preferences.
3. Put the computer to sleep.
4. Wake the computer.
5. Go back in to Network preferences, AirPort tab. Click the plus sign to add your network. Fill in the Network Name, choose the type of Security by clicking on the pop-down bar, enter password/code/phrase and click Add. NOTE: Do not connect to the network at this time.
6. Click Apply and Quit the Network Preferences.
7. On the Menu row, click the Airport icon and select your network. (IF your network does not show, choose Join Other Network. Fill in the Network Name, choose the type of Security by clicking on the pop-down bar, enter password/code/phrase and click Join.)
8. Verify connectivity
9. Put the computer to sleep.
10. Wake the computer.
11. Verify connectivity
