OSx Bandwidth Throttler (this will work for any *nix)

Basic Usage

• Download throttle.sh.
• Make the file executable with chmod +x throttle.sh
• Run it as the admin with sudo ./throttle.sh 45
• Turn everything off by running sudo ./throttle.sh stop

Values

• Numerical values will adjust to that speed in Kbytes/s e.g. sudo ./throttle.sh 54
• Typing stop will reset back to what it should be e.g. sudo ./throttle.sh stop
• Typing some predefined constants will result in some throttling e.g. sudo ./throttle.sh 3g

Constants taken from here (http://www.which.co.uk/technology/phones/guides/mobile-broadband/mobile-broadband-speed-and-usage-limits/)

• gprs - 30
• edge - 200
• 3g - 14000
• 4g - 3000000

Help!

If you manage to throttle your speed but can't get it to go back to normal you should run this command: sudo ipfw delete 1
