ConfigurazioneEthernetLxcSerraX

Attach your Gentoo LXC container to Serra with 802.1X authentication

Create the ethernet interface for your LXC container (on the phisical machine)

Edit /etc/lxc/YourLxcContainerName.conf adding lines inspired to the following

## Virtual itnerface type
lxc.network.type = macvlan
## Phisical ( on the phisical machine ) interface name attacched to serra
lxc.network.link = eth2
## Virtual ( on the LXC container ) interface name attacched to serra
lxc.network.name = eth2
lxc.network.flags = up
## Followings 3 line depends on the machine so you MUST change them!!
lxc.network.ipv4 = 131.114.186.Z/29
lxc.network.ipv4.gateway = 131.114.186.1
lxc.network.hwaddr = 26:99:38:32:f3:19

Configure the virtual interface ( on the LXC container )

Edit /etc/conf.d/net, the eth2 configuration should appear like this

# serra
config_eth2="   null"

Install the 802.1X authenticaticator ( on the LXC container )

To autenticate with 802.1X you need wpa_supplicant, to install it run

emerge -avq net-wireless/wpa_supplicant

Configure wpa_supplicant ( on the LXC container )

Edit /etc/conf.d/wpa_supplicant it should appear like this

wpa_supplicant_args="-ieth2 -Dwired"

Edit /etc/wpa_supplicant/wpa_supplicant.conf it should appear like this

# IEEE 802.1X works with EAPOL version 2, but the version is defaults 
#   to 1 because of compatibility problems with a number of wireless
#   access points. So we explicitly set it to version 2:
eapol_version=2

# When configuring WPA-Supplicant for use on a wired network, we don?t need to
#   scan for wireless access points. See the wpa-supplicant documentation if
#   you are authenticating through 802.1x on a wireless network:
ap_scan=0

network={
                key_mgmt=IEEE8021X
                eap=PEAP
                phase2="auth=MSCHAPV2"
                identity="yourLogin"
                password="yourPassword"
        }

Make wpa_supplicast start automagically at boot ( on the LXC container )

Ad wpa_supplicant to the default runlevel running

rc-update add wpa_supplicant default
