NAME
Net::Wireless::802_11::Scan::FreeBSD - A interface to the wireless interface AP scanning built into ifconfig on FreeBSD
VERSION
Version 0.0.0
SYNOPSIS
use Net::Wireless::802_11::Scan::FreeBSD;
my $scan = Net::Wireless::802_11::Scan::FreeBSD->new();
#scan for APs
my @APs=$scan->scan;
if ( $scan->error ){
warn('$scan->scan errored');
}
#print some information for each AP
my $APs_int=0;
while ( defined( $APs[$APs_int] ) ){
print 'SSID: '.$APs[$APs_int]{'ssid'}."\n".
'BSSID: '.$APs[$APs_int]{'bssid'}."\n".
'Chan: '.$APs[$APs_int]{'chan'}."\n".
'Sec: ';
my $security=none;
if ( $APs[$APs_int]{'WPA'} ){
$security='WPA1'
}
if ( $APs[$APs_int]{'RSN'} ){
$security='WPA2'
}
print $security."\n\n";
$APs_int++;
}
METHODS
new
This initializes the object.
At start the interface will be set to 'wlan0'. If you want to change this, you will need to call ifSet.
No error checking is needed as this will always succeed, as long as it is being ran on FreeBSD. This will throw a permanent error if $^O ne 'freebsd'.
my $scan=Net::Wireless::802_11::Scan::FreeBSD->new();
ifGet
This returns the current interface.
No error checking is needed as this will always succeed.
my $interface=$scan->ifGet;
ifSet
This sets the interface that will be scanned.
One argument is required and that is the interface name.
As long as the interface is defined, there is no need to do error checking.
#set the interface to wlan1
$scan->ifSet('wlan1');
scan
This runs "ifconfig -v $interface list scan".
my @APs=$scan->scan;
use Data::Dumper;
print Dumper(\@APs);
returned data
The returned data is a array of hashes.
ssid
The SSID of the AP.
This may be blank.
bssid
The BSSID of the AP.
chan
The channel it is on.
rate
The rate of the AP in question.
S:N
The signal noise ratio.
signal
The signal value from S:N.
noise
The noise value from S:N.
int
The beacon interval of the AP.
caps
This is the raw unparsed caps field.
Authorized
The station is permitted to send/receive data frames.
ERP
Extended Rate Phy (ERP). Indicates that the station is operating in an 802.11g network using extended transmit rates.
HT
The station is using HT transmit rates.
PowerSave
The station is operating in power save mode.
QoS
The station is using QoS encapsulation for data frame.
ShortPreamble
The station is doing short preamble to optionally improve throughput performance with 802.11g and 802.11b.
WPS
The station in question allows the use of WPS.
ATH
The AP in question supports Atheros protocol extensions.
WME
Indicates WME support.
WPA
The AP supports WPA, not to be confused with WPA2.
RSN
The AP supports RSN, WPA2.
VEN
The AP supports unknown vendor-specific extensions.
ERROR CODES/FLAGS
For information on error handling and the like, please see the documentation on Error::Helper.
1/notFreeBSD
$^O ne 'freebsd'. This module only works on FreeBSD.
2/ifUndef
Interface not defined.
3/ifconfigError
Ifconfig errored when trying to run "ifconfig -v $interface list scan".
This means it returned a non-0 exist code.
