Connection to wireless network - wpa

[Uwe Brauer]

Hello 

With respect to your message from 27 of June, I would like to ask you
the following, given your configuration file I tried to connect
manually in the following way
sudo wpa_supplicant -B -i eth1 -c /etc/wpa_supplicant/wirless.conf -D wext
sudo dhclient eth1

But I receive 
DHCPREQUEST on eth1 to 255.255.255.255 port 67
DHCPREQUEST on eth1 to 255.255.255.255 port 67
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 14
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 9
No DHCPOFFERS received.

And indeed I obtain no IP number.

When I try it via the kde-networkmanager interface it seems that 
my request is somehow cut.

My identity is oub at mat.ucm.es
but the system manager of my university tell me they only receive
oub@

Which of course is not correct.

Can anybody help me?
