50 utility listens for events generated by an
52 wireless network driver and relays them to
54 for possible processing.
55 The three event types that can occur
56 are media connect and disconnect events, such as when a wireless
57 interface joins or leaves a network, and media-specific events.
60 drivers that support WPA2 will generate media-specific events
61 containing PMKID candidate information which
63 needs in order to properly associate with WPA2-capable access points.
67 daemon works by listening for interface information events via
69 When it detects an event that was generated by an
71 interface, it transmits it via UDP packet on the loopback interface,
74 is presumably listening.
77 distribution includes its own version of this utility for use with
81 version performs the same functions as the
83 one, except that it uses an
85 and routing socket interface instead of WMI.
87 Note that a single instance of
89 is sufficient to scan for events for any number of
91 interfaces in a system.
95 daemon supports the following options:
96 .Bl -tag -width indent
101 will only process and forward media-specific events, which contain
102 PMKID candidate information, and not bother forwarding connect and
103 disconnect events, since
105 normally can determine the current link state on its own.
107 cases, the additional connect and disconnect events only confuse it
108 and make the association and authentication process take longer.
113 to run in the foreground and generate any output to the standard
114 error instead of using the
121 to emit notifications when it receives events.
