""" wicd - wireless connection daemon implementation.
|
|
|
|
This module implements the wicd daemon that provides network
|
|
connection management, for both wireless and wired networks. The daemon
|
|
must be run as root to control the networks, however the user interface
|
|
components should be run as a normal user.
|
|
|
|
class LogWriter() -- Class to redirect stdout and stderr to a log file.
|
|
class ConnectionWizard() -- DBUS interface to manage the network.
|
|
class ConnectionStatus() -- Updates the current connection state
|
|
def usage() -- Print usage information.
|
|
def daemonize() -- Daemonize the current process with a double fork.
|
|
def main() -- The wicd daemon main loop.
