I've configured WLAN with WPA2-PSK on my notebook EEE PC 1000H from Asus with Lenny.
I'd like to configure wireless interface in /etc/network/interfaces to switch from WPA2-PSK to a free open WiFi hotspot and back to the default WPA2-PSK if needed.
Now i have:
Code:
# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
# Wireless
allow-hotplug ra0
iface ra0 inet dhcp
wpa-driver wext
wpa-ssid my_essid
wpa-scan-ssid 1
wpa-ap-scan 2
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk my_secret_key
Do you use any GUI based network management tools or do you always hand edit the network interfaces file? I have had good success using wicd as my wired and wireless network management tool, and it can be run from either a GUI or a command line interface. I've used it precisely the way you indicate, too. By default, I use a WPA2/PSK secure access point, but I also use open hotspots, and occasionally other WPA2/PSK or even WEP access points, and wicd is capable of handling them.
