hi
Here is a script for toggling wifi on and off. Its the first script I've made (with the help of a friend); i'm sure this could be improved and made more efficient.
Hardware: MacMini OS 10.7.5, RouterBoard 6.7
Software: Growl and GrowlNotify, Automator, Terminal, SSH
Prereqs.: Create a key using ssh-keygen and import it into the Mikrotik Router, using RouterOS - RouterOS - MikroTik Documentation. Also, download and install Growl and GrowlNotify from http://growl.info
The script below, first turns on the WiFi interface on the MacMini, pauses for a few seconds to allow the Mac to connect to my wifi network, extracts the SSID of the connected network, and then uses an If-Then statement to enable wifi on the Mikrotik Router (if it is disabled), or to disable it (if it is enabled). The script then turns off the WiFi interface on the MacMini and an appropriate growl notification is made. The script is made in Automator, and application resides on my desktop. This makes it convenient to either turn on the wifi in my home, or to turn it off. However, my Mac needs to be turned on before the wifi is enabled or disabled.
/bin/bash shell script
turn wifi on from terminal, and pause for 6 seconds
networksetup -setairportpower en1 on && sleep 6
find SSID of current network
SSID=/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | grep -w '<insert-name-of-network-here>' | awk '{print $2}'
if wifi is available, then disable it, and display growl notification
if [ "$SSID" = "" ] ; then ssh -l admin-ssh -i ~/.ssh/id_dsa <insert-IP-of-Mikrotik-Router-here> "interface wireless disable 0" && /usr/local/bin/growlnotify -m "disabled" "WiFi" ; fi
if wifi is unavailable, then enable it, and display growl notification
if [ "$SSID" = "" ] ; then ssh -l admin-ssh -i ~/.ssh/id_dsa <insert-IP-of-Mikrotik-Router-here> "interface wireless enable 0" && /usr/local/bin/growlnotify -m "enabled" "WiFi" ; fi
turn wifi off from terminal:
networksetup -setairportpower en1 off
