Simulate network latency and packet loss on Mac OS X (requires sudo)

hinder.sh

#!/bin/bash

set -e

USAGE="Usage: $0 [ip_address | reset]"

if [ "$#" == "0" ]; then
  echo "$USAGE"
  exit 1
fi

ip=$1

if [ "$ip" = "reset" ]; then
  printf 'Resetting... '
  sudo ipfw list | grep 'pipe' | awk '{print $1}' | while read name; do sudo ipfw delete $name ; done
  echo 'Done'
else
  echo "Creating rules to simulate latency to $ip... "

  # Create 2 pipes and assigned traffic to and from our webserver to each:
  sudo ipfw add pipe 1 ip from any to $ip
  sudo ipfw add pipe 2 ip from $ip to any

  # Configure the pipes we just created:
  sudo ipfw pipe 1 config delay 250ms bw 1Mbit/s plr 0.1
  sudo ipfw pipe 2 config delay 250ms bw 1Mbit/s plr 0.1

  echo "Done"
fi

Do you have a script for mac sierra? ipfw is no longer installed.

Thanks
