A simple script that’ll toggle your System Preferences proxy settings on a Mac. It takes one argument- the name of the interface on which to toggle the proxy (eg, ‘Airport’ or ‘Ethernet’). You can easily wrap this with an automator script using the “Get specified text” action to provide the argument and the ‘Shell Script’ action to run the script.
Uses growl to notify you of what it’s done. That can be removed if you want- just delete the end of the script below the relavent comment.
Nothing too complex here- uses the mac command line ‘networksetup’ tool, which allows command-line modification of network setting, to get and set the proxy state. Then it uses the mac command line ‘osascript’ tool, which runs apple script, to notify growl. The applescript in question just registers itself, then sends the message.
# Get current status
interface=$1
status=`networksetup -getsocksfirewallproxy $interface | grep "^Enabled: [a-zA-z]*$"`
echo "status=$status"
if [ "`echo $status | grep "No"`" ]; then
newState="on"
else
newState="off"
fi
# Set new state
networksetup -setsocksfirewallproxystate Airport $newState
# Print message (delete after here to remove growl notification)
if [ "$status" ]; then
message="$interface socks proxy is now $newState"
else
message="Error toggling socks proxy on interface:'$interface'"
fi
