wireless problem at school

i try to connect to our wireless network 'eduroam' in school .. but without success
i need to run wpa_supplicant .. so i run it with "wpa_supplicant -B -i eth1 -c /etc/wpa_supplicant.conf -D wext" .. then i try to run dhclient to get ip from access point .. but i get this:

#dhclient eth1

DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 3
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

then i just try wpa_cli to see the output .. and that is

> <2>Authentication with 00:00:00:00:00:00 timed out.
<2>Trying to associate with 00:11:5c:c3:87:b0 (SSID='eduroam' freq=2462 MHz)

i have try iwlist eth1 scan to see if there i some network detected:P and there is few eduoram's.
with kismet i can also see al that networks

.. here is the conf file for wpa_supplicant

 ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
network={
    ssid="eduroam"
    proto=WPA WPA2
    key_mgmt=WPA-EAP
    group=CCMP TKIP
    eap=TTLS
    anonymous_identity="anonymous@organisation.domain.name"
    phase2="auth=PAP"
    identity="username@organisation.domain.name"
    password="password"
}

oh and yes, i have correct username and password caus i can go online on windows.

windows users must install SecureW2 Client

how can i solve that problem

and here is the 'how-to' for our eduroam: HOW TO

i only try wext drivers .. maybe with bcm43xx or ndiswrapper it'll work? .. i'll try that tomorrow and let you know.

Re: wireless problem at school

Hi, I accidentally bumped into this post when I was searching for something else. Anyway, if you still can't connect, add ca_cert field to /etc/wpa_supplicant.conf or whatever config file you specify when you run wpa_supplicant.

network={
...
  ca_cert="/etc/ssl/certs/cacert.der"
...
}

I downloaded cacert.der from my faculty (FE, uni-lj) webpage. It works for me, so it should for you too unless you have some hw problems. Oh, and don't test at CTK, go to a faculty or IJS.
