.TH WPA 8
.SH NAME
wpa \- Wi-Fi Protected Access setup
.SH SYNOPSIS
.B aux/wpa
[
.B -dp12
] [
.B -s
.I essid
]
.I dev
.SH DESCRIPTION
.I Wpa
handles the authentication and key exchange with WPA
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 or
pap/chap credentials into factotum, otherwise the key has to be
already present in factotum or an interactive key prompter like
auth/fgui (see
.IR factotum (4))
needs to provide it.
.PP
The authentication protocol is initiated by the
wireless access point so
.I wpa
will background itself after the keyprompt and establish
the encryption automatically as needed.
The optional
.B -1
or
.B -2
arguments can be used to select between WPA1/TKIP
(default) or WPA2/CCMP encryption with WPA PSK.
.PP
The
.B -d
option enables debugging and causes
.I wpa
to stay in foreground writing protocol messages to
standard error.
