1 #!/bin/sh 2 ################################################################################ 3 # test_LAN_triple-isolate__piece_of_cake.qos (Cero3 Shaper) 4 # 5 # Abstract: 6 # This is a one band cake and ipv6 enabled shaping script for Ethernet 7 # gateways. This exists for the purpose of testing cake's different isolation 8 # options, specifically the non-directional triple-isolate feature that promises 9 # to finally tackle the bit-torrent hole in simple.qos. 10 # This specific version is supposed to be used on LAN interfaces: 11 # the script's ingress direction equals the internet/WAN upload direction 12 # the script's egress direction equals the internet/WAN download direction 13 # 14 # NOTE: Shaping on a LAN interface only affects machines connected via that 15 # LAN interface, so typically WIFI/WLAN traffic will not be shaped! 16 # 17 ################################################################################ 18 # 19 # This program is free software; you can redistribute it and/or modify 20 # it under the terms of the GNU General Public License version 2 as 21 # published by the Free Software Foundation. 22 # 23 # Copyright (C) 2012-2016 24 # Michael D.
