Hello!


You could say I'm new to linux- I have already used it a year ago, with no
problems.. but let's say i have forgotten almost everything

my problem is that i cannot connect to internet using wired connections-
this was also the original reason why i changed my sistem back to windows.
The problem is, that I'm rigt now living in china- when i got here I was
using Ubuntu 8.04- and i had a problem with ipv6- i could not disable it,
and therefore i wasn;t able to use the internet connection. right now i'm
using 9.04 and vista.
I'm living in a university campus, so I have no iformation on their ISP,
router, basically I dont have any other information except the assigend IP,
DNS, gateway...

I am conected, my hardware is working properly, the settings are correct,
but it seems that my connection just wont work- it just connecting..... like
it cannot even establish a connection with the server...

I've also tried su echo 0 > /proc/sys/net/ipv6/conf/all/disable_ipv6 and it
didn't work

and the ping

uros at ubuntu:~$ ping www.youku.com
ping: unknown host www.youku.com
uros at ubuntu:~$ ping www.google.com
ping: unknown host www.google.com

the result for the university website- actually everytime you go online you
first have to go to this address and enter your username,pass so that you
are authenticated and so you can use the internet.. dont really know if this
is important or not..

uros at ubuntu:~$ ping 2.2.2.3
PING 2.2.2.3 (2.2.2.3) 56(84) bytes of data.
