Hi,
Ive got a question from the user side, hope this belongs here.
I got the impression, that to be able to connect to a 802.1X wired
network, which is not password protected (certificates only) I need to
use wpasupplicant.
I cant save a connection like that in network manager as long as the
username and password is empty. Wired and wireless networks were
disabled in the network manager before running the code.
I want to connect to my companies wired Network with my laptop
Using Toshiba Portégé Z50 (i5-4210U) RV2015
Intel Core i5-4210U (1.70GHz, 2.7GHz)
Network Card: Intel(R) Ethernet Connection I218-V
with a freshly installed Xubuntu 14.04.
The network admin stated that the following informations about the
network are correct:
key_mgmt=IEEE8021X
eap=PEAP
anonymous_identity="some identity"
ca_cert="path to ca.cer"
phase2="auth=mschapv2"
/etc/wpa_supplicant.conf:
---------------------------
# Where is the control interface located
ctrl_interface=/var/run/wpa_supplicant
# Who can use the WPA frontend? 0 or Group Name
ctrl_interface_group=0
# Which version of IEEE 802.1X - Set it to 2
eapol_version=2
# Scanning for wireless access-points?
ap_scan=0
#Network settings for the company network
network={
key_mgmt=IEEE8021X
eap=PEAP
anonymous_identity="some identity"
ca_cert="path to ca.cer"
phase2="auth=mschapv2"
private_key="path to privkey2.pem"}

Trying to establish the connection:
sudo wpa_supplicant -c /etc/wpa_supplicant.conf -dd wired -i eth0

I would be very happy about an explanation about what failed and maybe
how to solve this problem.
Thank you very much,
