I wanted to set my laptop (Fedora 14) using wpa_supplicant in such a way that it should connect to AP with roaming consortium ID 2233445566 with domain homenet.com

I don't know why it crash or reinitialized. It does not show any log for failure but it just restart.

Yes, you may be right. The log say

My credential are given below. Do we require more

Actually I can not find any log for this failure. It restart or reinitialized without any reason.

When it is connected to some different SSID and I give interworking_select command. Again wpa_supplicant crash and restart

I set cred
cred={
domain="homenet.com"
roaming_consortium=2233445566
}
Is it not enough to show in list_cred or not?
> So you don't actually have any credentials configured? In that case,

I set only network without any specific SSID block as
network={
key_mgmt=NONE
}
I have not set any SSID as I want to connect to AP with consortium ID 2233445566 irrespective of SSID.
