#!/usr/bin/perl -w
## ----- ----- ----- ----- ----- ----- ----- ----- ----- -----
## LANforge server script for associating virtual stations
## to an arbitrary SSID. You have options for creating a series
## of Layer-3 connections per station created. Support for various
## security modes for stations: wep, wpa, wpa2.
##
## Install:
## copy this script to /home/lanforge/scripts
##
## Preparation:
## This script expects a free radio (like wiphy0) to create
## wifi stations on. It also expects an upstream wired port to
## make tcp connections to. These ports should be able to
## communicate with each other.
##
## Usage Overview:
## Use -h to show options.
## There are two activities that this script presently performs:
##
## Step1: create 1 wifi station, pass traffic to the upstream port
## back and forth, and then disassociate. This activity could
## be split into several steps if testing traffic up- or
## down-stream only is desired.
##
## Step2: create many wifi stations, wait until we see IPs appear
## on them and then disassociate all of them. This activity could
## also be modified to test for wifi association instead of address
## aquisition. The present example uses static address assignment.
##
## add: create and delete WiFi Virtual Radios. Also has option to
## create station on specified virtual radio.

[--quiet { yes | no }] # debug output; -q
[--log_cli] # enables CLI command printing to STDOUT
# same effect when setting env var LOG_CLI=STDOUT
## AP selection
[--radio {name}] # e.g. wiphy2
[--channel {channel}] # e.g. 52, 161, 153 , 6E cannels end in an 'e' or add 190 to the 6e channel
# please check the LANforge GUI to verify resulting selection
# center channels might be selected differently than you intended
[--antenna {1,2,3,4}] # select number of antennas
[--ssid {ssid}] # e.g. jedtest
[--bssid {aa:bb:cc:00:11:22, or DEFAULT} # AP BSSID to connect to
[--security {open|wep|wpa|wpa2|wpa3|wpa2,wpa3}] # station authentication type, Default is open

## station configuration
[--num_stations {$num_stations}] # Defaults to 1
[--first_sta {$first_sta}]
[--first_ip {DHCP | DHCP6 | DHCP,DHCP6 |<ip address>}]
# use DHCP,DHCP6 to enable both DHCP and DHCP6
[--netmask {$netmask}]
[--gateway {$gateway}]
[--change_mac {0|1}]
# If this is set to 0, then we will not change MAC if the station already exists.
# This is now the default behaviour.
[--mac-pattern {$default_mac_pat}]
# xx : uses parent radio octet
# [0-9a-f] : use this value for octet
# * : generates random octet
# Use quotes around this argument! EG:
# --mac_pattern '00:xx:*:*:xx:xx'
## connection configuration
[--cxtype {tcp/tcp6/udp/udp6}] # use a tcp/udp connection, default tcp
[--upstream {name|$upstream_port}]
# could be AP or could be port on LANforge
# connected to WAN side of AP

[--action {step1,step2,add,del,del_all_phy}]
# step1: creates <num_stations> stations and L3 connections
# step2: does bringup test
# add: creates station on specified radio, or radio if no stations are requested
# del: Delete the specified port.
# del_all_phy: Delete all interfaces with the specified parent device.
[--traffic_type {separate|concurrent}]

[--db_postload {scenario name}]
# load this database after running connections,
# option intended as a cleanup step
## virtual radio configuration
[--vrad_chan {channel}]
[--port_del {name}] # deletes port given
Examples:
## connecting to an open AP, at 2Mbps, for 20 minutes
$0 --action step1 --radio wiphy0 --ssid ap-test-01 \\
--bps-min 2000000 --duration 1200 --upstream eth1
$0 --action step2 --radio wiphy2 --ssid jedtest \\
--first_sta sta100 --first_ip DHCP --num_stations 3 \\
--security wpa2 --passphrase jedtest1 --mac_pattern 'xx:xx:xx:*:*:*'
Note: mac_pattern is NOT a regex, it is octet based tokens:
* = rand(256)
xx = parent mac octet
You can specify a numeric mac address (d0:01:00:00:af:ff) and it can get incremented
## using a second lanforge system to connect to wpa2 AP:
$0 --mgr 192.168.100.1 --resource 2 --radio wiphy2 \\
--ssid jedtest --passphrase 'asdf1234' \\
--num_stations 10 --first_sta sta400 \\
--first_ip DHCP --upstream eth1 --action step1
## (Windows) using a beginning database and saving the resulting database:
C:\\Users\\bob> cd "c:\\Program Files (x86)\\LANforge-Server\\scripts"
C:\\Program Files (x86)\\LANforge-Server\\scripts>perl lf_associate_ap.pl --mgr jedtest \\
--resource 2 --radio wiphy2 --first_ip DHCP \\
--duration 10 --bps-min 10k --bps-max 20M --cxtype tcp \\
--ssid jedtest --passphrase jedtest1 --security wpa2 \\
--first_sta 300 --db_preload Radio2 --db_save run_results --num_stations 3
## connecting to wpa AP:
$0 --mgr 192.168.100.1 --radio wiphy0 \\
--ssid jedtest --passphrase 'asdf1234' --security wep \\
--num_stations 10 --first_sta sta400 \\
--first_ip DHCP --upstream eth1 --action step1
## creating and deleting a virtual radio:
$0 --mgr 192.168.100.1 --resource 2 \\
--radio vphy1 --vrad_chan 36 --action add
$0 --mgr 192.168.100.1 --resource 2 \\
--port_del vrad1 --action del
## Adding a station to a new or existing virtual radio:
$0 --mgr 192.168.100.1 --resource 2 \\
--radio vphy1 --first_sta sta0 --first_ip DHCP --ssid my_ssid --action add
## Add lots of stations to a radio
$0 --mgr ben-ota-1 --resource 2 --action add --radio wiphy0 --ssid Lede-ventana \\
--first_sta sta100 --first_ip DHCP --num_stations 63
## Delete all virtual devices on wiphy0
$0 --mgr ben-ota-1 --resource 2 --action del_all_phy --port_del wiphy0
## Create a station and set Flags
$0 --mgr localhost --radio wiphy1 --ssid sushant-AP --action add --num_stations 1 \\
