Unkown Host Error KDE 4.2 RC

Hi. So, i’ve recently solved my problem with KDM but now I’ve ran into trouble with my internet connection. I had this issue with Ubuntu so I thought that it would go away if I changed the linux distro I use to OpenSuse (and also start experimenting with other linux flavours) but it didn’t. The fact is that I can open all the webs I usually see perfectly, but I can’t enter megaupload neither rapidshare. Whenever I try to access a megaupload link or even to it’s home page this error appears:
Opera:

Error! 
Could not locate remote server
You tried to access the address http://www.rapidshare.com/, which is currently unavailable. Please make sure that the Web address (URL) is correctly spelled and punctuated, then try reloading the page.
Make sure your Internet connection is active and check whether other applications that rely on the same connection are working.

Konqueror:

The requested operation could not be completed
Unknown Host
Details of the Request:
URL: http://www.megaupload.com/
Protocol: http
Date and Time: Sunday 25 January 2009 03:36
Additional Information: Host not found
Description:
An unknown host error indicates that the server with the requested name, www.megaupload.com, could not be located on the Internet.
Possible Causes:
The name that you typed, www.megaupload.com, may not exist: it may be incorrectly typed.
There may have been a problem with your network connection.
There may have been a problem with your network configuration. If you have been accessing the Internet with no problems recently, this is unlikely.
Possible Solutions:
Check your network connection status.
Contact your appropriate computer support system, whether the system administrator, or technical support group for further assistance.

Terminal:


jake@linux-soc5:~> ping www.megaupload.com
ping: unknown host www.megaupload.com

The really strange thing is that I can enter to this webs if I take out the “www.” from the adress.
I use an ADSL modem and I connect it to a wi-fi router. I connect my PC through an ethernet cable. This problem doesn’t come from the router, I’ve tried connecting my PC directly to the modem but the error was still there.
I know someone may start saying that I shooldn’t be complaining if only i’ve got to do is to take out the “www.” and the job is done but I think I should have a fully functional OS, if not I would have stayed with Windows (by the way, this issue doesn’t appear in Windows).
If you need me to post any information about my system please tell me and I’ll look for it in order to solve this issue.
Thanks.

Works fine here with the www in komq and FF.

Thanks for the reply. I know that megaupload’s and rapidshare’s webs are working and my problem is definetely coming from my computer (I know it’s not of my router since ,as I’ve already said, I tried connecting my PC directly to the modem and it still didn’t work). Recently I’ve tried deactivating opensuse’s firewall but nothing happened.
Really, I don’t have any clue at all about how to resolve this issue and it’s really bothering me since I can’t download anything from the most used servers (megaupload and rapidshare). :shame:

Try disabling IPV6 in@

Yast>System>/etc/sysconfig Editor

Just use the search button for ipv6 and disable it for KDE.

Might help.

however I have that setting enabled here and did not notice any delay
but that not mean anything :slight_smile:

First of all: Thanks for helping me baskitcaise. :slight_smile:

I tried to disable ipv6 from /etc/sysconfig just like you told me, then rebooted but still MEGAUPLOAD - The leading online storage and file delivery service and RapidShare: Easy Filehosting didn’t work. I also tried to disable ipv6 from opensuse’s network manager and then rebooted again but nothing happened. Do you have any other ideas of what may be causing this issue?

Sorry for the double post but I’m getting a bit anxious. Can’t anyone besides baskitcaise in OpenSuse’s official forums help me with my problem? I’m not looking for an exact solution, at least if you know any place or forum where I could get some help because it’s been more than a week since the last answer to my thread and I still cannot use OpenSuse as my primary OS because of this problem :.

Thanks.

OK, I’ll give this a shot. Sometimes, particularly with ADSL setups you have to mess around with the MTU setting. It should be set to 1492 by default, but you may have to lower it. It can be set in YaST network card settings, but you have to find an optimal value first. See this DSLreports link for general background.

http://www.dslreports.com/tweaks/MTU

In Linux you have to use the ifconfig to set MTU temporarily, .e.g;

ifconfig eth0 mtu 1492

Try lowering it in increments on 10 and test in between. Make it permanent in YaST. ifconfig will tell you what it is currently set to.
