[solved] Cant configure wpa_supplican to connect to eduroam.

I'm trying to connect to the network, eduroam and Kent university. I downloaded the graphical wcid and it won't list any networks so I'm now trying to connect manually. I know on my Ubuntu desktop I have wpa2 security with PEAP.

I am trying to follow the wpa_supplicant tutorial. But I have run into some problems.

The output of iw wlan0 scan is:

I assume this means that my wi-fi card is working. Does it? If so, I don't know why wicd can't find any networks. I would prefere to do it manually anyway though.

I then edited /etc/wpa_supplicant.conf. It now cantains:

ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel
network={
	ssid="eduroam"
	proto=RSN
	pairwise=CCMP
	eap=PEAP
	identity="jfp6@kent.ac.uk"
	password="***"
}

I then tried:

wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf

but it failed to load/parse /etc/wpa_supplicant.conf.

Line 9: WPA-PSK accepted for key management, but no PSK configured.
Line 9: failed to parse network block.
Failed to read or parse configuration '/etc/wpa_supplicant.conf'.

If I select no key management then it parses. If I then proceed to type dhcpcd wlan0 it times out and ip addr show wlan0 prints nothing.

If you can explain to me what I'm doing wrong and how it should be done and why that would be great. Thanks.

Extra info:

rfkill lists everything as unblocked.
ifconfig lists wlan0 as up.

Re: [solved] Cant configure wpa_supplican to connect to eduroam.

I've become pretty comfortable with manual wireless connection methods - but I still never hand-edit wpa_supplicant.conf.  I highly recommend using wpa_passphrase to configure this file for you.  It seems the file is not correctly filled (no psk) and that leads to the error you are getting.

As an aside I laughed a bit at the refreshingly honest thread title - but while honesty is great, information is better.  If you include a breif statement of the error/problem in the title you may get better results.

Re: [solved] Cant configure wpa_supplican to connect to eduroam.

I think the part that makes it trickier than normal is the "eduroam" part.   I have seen many stuggle pretty hard with this.  I have never used it, so I cannot weigh in, sorry.

Re: [solved] Cant configure wpa_supplican to connect to eduroam.

Sorry, I feel like I should have done some more googling but it only occured to me while writing this post that other universities use eduroam. With a quick google search I found a solution.I will redeam myself by posting my solution.
1. ip link set wlan0 up where wlan0 is your wireless interface you are trying to connect from.

2. Create/edit /etc/wpa_supplicant.conf to look like:

ctrl_interface=/var/run/wpa_supplicant
network={
    ssid="eduroam"
    scan_ssid="eduroam"
    proto=RSN
    key_mgmt=WPA-EAP
    pairwise=CCMP
    group=CCMP
    eap=PEAP
    identity="abc1@university_name.ac.uk"
    password="PASSWORD"
    ca_cert="/usr/share/ca-certificates/mozilla/GlobalSign_Root_CA.crt"
    phase2="auth=MSCHAPV2"
}

3. As root:
wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf

4. then dhcpcd wlan0 again where wlan0 is the interface you are trying to connect from.

On a side note, You should send this link to the head of IT Security at Kent University.
