Wireless Internet PEAP Authentication Using wpa_supplicant

[McAgnel]

I was trying to configure ubuntu installed on my lappy Sony vaio(Vaio Queen :bleh to get it connected to a network protected with PEAP. It seemed to be a hard task when i tried to do with xsupplicant. After a long time of googling and configuring with the system, it seemed to work pretty fine. But the effort required is very much minimal as you will notice here with wpa_supplicant.

1. Install wpa_supplicant application

apt-get install wpa_supplicant

2. Edit /etc/wpa_supplicant/wpa_supplicant.conf to include something like:

network={

ssid="YOUR NETWORK NAME GOES HERE"

scan_ssid=1

key_mgmt=IEEE8021X

eap=PEAP

phase2="auth=MSCHAPV2"

identity="netid/username"

password="password"

}

Remember to remove any read/write permissions for other users and group users since the conf file contains your password in it.

3. Edit your /etc/network/interfaces file:

iface eth1 inet dhcp

wpa-driver wext

wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

where eth1 is your wireless card interface.

4. Restart the networking service

sudo /etc/init.d/networking restart

5. Connect to the internet

sudo ifup eth1

6. To disconnect

sudo ifdown eth1

It has been sometime since I last posted in TE hyeah:

Guys,

please ignore step 1.

Incase you have multiple networks in different places then add a similar block as given in step 2 with the ID of the new network in the same file.

Eg,

network={
ssid="network1"
scan_ssid=1
key_mgmt=IEEE8021X
eap=PEAP
phase2="auth=MSCHAPV2"
identity="netid/username"
password="password"
}

network={
ssid="network2"
scan_ssid=1
key_mgmt=IEEE8021X
eap=PEAP
phase2="auth=MSCHAPV2"
identity="netid/username"
password="password"
}

Another update,

The device need not be disabled and enabled everytime you need to connect and disconnect.

One can use the dhclient to do the same

This can be used to log into some universities which uses PeaP authentication.
