  válasz Tamy #31 üzenetére

  Találtam még egy ilyen megoldást, de ez végképp nem megy (persze nem OpenWrt-re van):

  #!/bin/bash
  #
  # tc uses the following units when passed as a parameter.
  # kbps: Kilobytes per second
  # mbps: Megabytes per second
  # kbit: Kilobits per second
  # mbit: Megabits per second
  # bps: Bytes per second
  # Amounts of data can be specified in:
  # kb or k: Kilobytes
  # mb or m: Megabytes
  # mbit: Megabits
  # kbit: Kilobits
  # To get the byte figure from bits, divide the number by 8 bit
  #
  
  #
  # Name of the traffic control command.
  TC=/sbin/tc
  
  # The network interface we're planning on limiting bandwidth.
  IF=eth0 # Interface
  
  # Download limit (in mega bits)
  DNLD=1mbit # DOWNLOAD Limit
  
  # Upload limit (in mega bits)
  UPLD=1mbit # UPLOAD Limit
  
  # IP address of the machine we are controlling
  IP=216.3.128.12 # Host IP
  
  # Filter options for limiting the intended interface.
  U32="$TC filter add dev $IF protocol ip parent 1:0 prio 1 u32"
  
  start() {
  
  # We'll use Hierarchical Token Bucket (HTB) to shape bandwidth.
  # For detailed configuration options, please consult Linux man
  # page.
  
  $TC qdisc add dev $IF root handle 1: htb default 30
  $TC class add dev $IF parent 1: classid 1:1 htb rate $DNLD
  $TC class add dev $IF parent 1: classid 1:2 htb rate $UPLD
  $U32 match ip dst $IP/32 flowid 1:1
  $U32 match ip src $IP/32 flowid 1:2
  
  # The first line creates the root qdisc, and the next two lines
  # create two child qdisc that are to be used to shape download
  # and upload bandwidth.
  #
  # The 4th and 5th line creates the filter to match the interface.
  # The 'dst' IP address is used to limit download speed, and the
  # 'src' IP address is used to limit upload speed.
  
  }
  
  stop() {
  
  # Stop the bandwidth shaping.
  $TC qdisc del dev $IF root
  
  }
  
  restart() {
  
  # Self-explanatory.
  stop
  sleep 1
  start
  
  }
  
  show() {
  
  # Display status of traffic control status.
  $TC -s qdisc ls dev $IF
  
  }
  
  case "$1" in
  
  start)
  
  echo -n "Starting bandwidth shaping: "
  start
  echo "done"
  ;;
  
  stop)
  
  echo -n "Stopping bandwidth shaping: "
  stop
  echo "done"
  ;;
  
  restart)
  
  echo -n "Restarting bandwidth shaping: "
  restart
  echo "done"
  ;;
  
  show)
  
  echo "Bandwidth shaping status for $IF:"
  show
  echo ""
  ;;
  
  *)
  
  pwd=$(pwd)
  echo "Usage: tc.bash {start|stop|restart|show}"
  ;;
  
  esac
  
  exit 0
