Set variable for password in netconfig.rb #43
Description
Hi Guys,
Started to play around with Concerto a few days ago, it is awesome, but noticed that it can, but out of the box can't connect to encrypted wireless networks (wpa personal) so I added a field in ../application/views/netsettings.erb which is fine and tried to add an instance variable in ../lib/bandshell/netconfig.rb @pwas:
class WirelessConnection
def initialize(args={})
@SSID = args['ssid'] || ''
@interface_name = args['interface_name'] if args['interface_name']
@wpa_config_file = '/tmp/wpa_supplicant.concerto.conf'
@pwas = args['pwas'] || ''
end
attr_accessor :pwas, :ssid, :interface_name
def config_interface_name
# If the user has requested a specific interface, use it.
# Otherwise, just pick the first wlan interface, assuming
# it works and all wlan interfaces have approximately equal
# reception. When this assumption is wrong the user must force.
if @interface_name && @interface_name != ''
@interface_name
else
self.class.interfaces[0].name
end
end
def validate
if @ssid == ''
fail "Need SSID for wireless connection"
end
end
def safe_assign
[ :pwas, :ssid, :interface_name ]
end
def write_configs
# Write a wpa_supplicant.conf file for an unsecured network.
File.open(@wpa_config_file, 'w') do |wpaconf|
# long lines, sorry!
wpaconf.puts "ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev"
wpaconf.puts "network={"
wpaconf.puts "ssid=\"#{@ssid}\""
wpaconf.puts "scan_ssid=1"
wpaconf.puts "key_mgmt=wpa"
wpaconf.puts "password=#{@pwas}"
wpaconf.puts "}"
end
end
def interfaces_lines
# This links the wpa config to the interfaces file.
["wpa-conf #{@wpa_config_file}"]
end
def args
{
'interface_name' => @interface_name,
'ssid' => @ssid
'pwas' => @pwas
}
end
This clearly not working, can you please advise where can I set this variable to make sense?
Thanks in advance!

@asquared Would adding a password field to pass along to wpa_supplicant will be sufficient here? It wouldn't seem to me to be that simple...

It looks like the key_mgmt option needs to be set to WPA-PSK and the option for the password is then called "psk", not "password".
I would also advocate for making this a new class of connection, perhaps a subclass of WirelessConnection, or an object that plugs into WirelessConnection. There are many different kinds of wireless authentication that might be in use in a Concerto deployment, so we want to factor this in a way that allows new methods to be added easily.

For reference, here's the man page for wpa_supplicant.conf: http://manpages.ubuntu.com/manpages/hardy/man5/wpa_supplicant.conf.5.html

Guys, the question is not exactly about wpa_suppilcant, I know how to configure it, was just posting a silly example (was lazy to copy from my vm, sorry). The problem what I have unfortunately is that I'm not able to define a variable to the password field on the GUI which would pass the input to the wpa_supplicant eventually. Think it would be awesome to have a function like that.
