Running Authenticator in a network namespace
|
||||
============================================
|
||||
|
||||
In some cases it might be useful to run hostapd in a network namespace to
|
||||
provide real separation between the two network interfaces. First create
|
||||
the "hostap" named network namespace:
|
||||
|
||||
sudo ip netns add hostap
|
||||
|
||||
Now move the network interface of hostapd into the "hostap" named network
|
||||
namespace:
|
||||
|
||||
sudo ip link set veth0 netns hostap
|
||||
|
||||
Inside the "hostap" named network namespace the loopback interface needs
|
||||
to be brought up and also the network interface:
|
||||
|
||||
sudo ip netns exec hostap ip link set lo up
|
||||
sudo ip netns exec hostap ip link set veth0 up
|
||||
|
||||
Then execute hostapd inside the network namespace:
|
||||
|
||||
sudo ip netns exec hostap ./hostapd wired_hostapd.conf
|
||||
|
||||
After that run wpa_supplicant as described above.
