.SH DESCRIPTION
|
|
|
|
|
.I Wpa
|
2013-03-10 23:25:01 +00:00
|
|
|
handles the authentication and key exchange with WPA
|
2013-03-09 18:18:00 +00:00
|
|
|
protected wireless networks.
|
|
|
|
|
.PP
|
|
|
|
|
The
|
|
|
|
|
.I dev
|
|
|
|
|
parameter specifies the network interface that needs
|
|
|
|
|
to be setup with WPA.
|
|
|
|
|
The
|
|
|
|
|
.I essid
|
|
|
|
|
can be set with the
|
|
|
|
|
.I -s
|
|
|
|
|
option. Otherwise, the previously configured essid
|
|
|
|
|
on the interface will be used.
|
|
|
|
|
The
|
|
|
|
|
.B -p
|
|
|
|
|
option will prompt and install the preshared key into
|
|
|
|
|
.IR factotum (4),
|
|
|
|
|
otherwise the key has to be already present in
|
2013-03-10 23:25:01 +00:00
|
|
|
factotum or an interactive key prompter like
|
2013-03-09 18:18:00 +00:00
|
|
|
.IR fgui (4)
|
|
|
|
|
needs to provide it.
|
|
|
|
|
.PP
|
|
|
|
|
The authentification protocol is initiated by the
|
|
|
|
|
wireless access point so
|
|
|
|
|
.I wpa
|
|
|
|
|
will background itself after the keyprompt and establish
|
|
|
|
|
the encryption automatically as needed.

.B -1
|
|
|
|
|
or
|
|
|
|
|
.B -2
|
|
|
|
|
arguments can be used to select between WPA1/TKIP
|
|
|
|
|
(default) or WPA2/CCMP encryption.
