# CHANGES
# -------
# v0.3a2- fixed bug in "if" operator. Thanks kad@dgtu.donetsk.ua.
# v0.3a-  added TIME parameter. Example:
#         TIME=00:00-19:00;64Kbit/6Kbit
#         So, between 00:00 and 19:00 RATE will be 64Kbit.
#         Just start "cbq.init timecheck" periodically from cron (every 10
#         minutes for example).
#         !!! Anyway you MUST start "cbq.init start" for CBQ initialize.
# v0.2 -  Some cosmetique changes. Now it more compatible with
#         old bash version. Thanks to Stanislav V. Voronyi
#         <stas@cnti.uanet.kharkov.ua>.
# v0.1 -  First public release
# 
# README
# ------
# 
# First of all - this is just a SIMPLE EXAMPLE of CBQ power.
# Don't ask me "why" and "how" :)
# 
# This is an example of using CBQ (Class Based Queueing) and policy-based
# filter for building smart ethernet shapers. All CBQ parameters are
# correct only for ETHERNET (eth0,1,2..) linux interfaces. It works for
# ARCNET too (just set bandwidth parameter to 2Mbit). It was tested
# on 2.1.125-2.1.129 linux kernels (KSI linux, Nostromo version) and 
# ip-route utility by A.Kuznetsov (iproute2-ss981101 version). 
# You can download ip-route from ftp://ftp.inr.ac.ru/ip-routing or
# get iproute2*.rpm (compiled with glibc) from ftp.ksi-linux.com.
# 
# 
# HOW IT WORKS
# 
# Each shaper must be described by config file in $CBQ_PATH
# (/etc/sysconfig/cbq/) directory - one config file for each CBQ shaper.
# 
# Some words about config file name:
# Each shaper has its personal ID - two byte HEX number. Really ID is 
# CBQ class.
# So, filename looks like:
# 
# cbq-1280.My_first_shaper
# ^^^ ^^^  ^^^^^^^^^^^^^
#  |  |            |______ Shaper name - any word
#  |  |___________________ ID (0000-FFFF), let ID looks like shaper's rate
#  |______________________ Filename must begin from "cbq-" 
# 
# 
# Config file describes shaper parameters and source[destination] 
# address[port].
# For example let's prepare /etc/sysconfig/cbq/cbq-1280.My_first_shaper:
# 
# ----------8<---------------------
# DEVICE=eth0,10Mbit,1Mbit
# RATE=128Kbit
# WEIGHT=10Kbit
# PRIO=5
# RULE=192.168.1.0/24
# ----------8<---------------------
# 
# This is minimal configuration, where:
# DEVICE:  eth0   - device where we do control our traffic
#          10Mbit - REAL ethernet card bandwidth
#          1Mbit  - "weight" of :1 class (parent for all shapers for eth0),
#                   as a rule of thumb weight=batdwidth/10.
#          100Mbit adapter's example: DEVICE=eth0,100Mbit,10Mbit
#          *** If you want to build more than one shaper per device it's
#              enough to describe bandwidth and weight once  - cbq.init
#              is smart :) You can put only 'DEVICE=eth0' into cbq-* 
#              config file for eth0.
# 
# RATE:    Shaper's speed - Kbit,Mbit or bps (bytes per second)
# 
# WEIGHT:  "weight" of shaper (CBQ class). Like for DEVICE - approx. RATE/10
# 
# PRIO:    shaper's priority from 1 to 8 where 1 is the highest one.
#          I do always use "5" for all my shapers.
# 
# RULE:    [source addr][:source port],[dest addr][:dest port]
#          Some examples:
# RULE=10.1.1.0/24:80         - all traffic for network 10.1.1.0 to port 80
#                               will be shaped.
# RULE=10.2.2.5               - shaper works only for IP address 10.2.2.5   
# RULE=:25,10.2.2.128/25:5000 - all traffic from any address and port 25 to
#                               address 10.2.2.128 - 10.2.2.255 and port 5000
#                               will be shaped.
# RULE=10.5.5.5:80,           - shaper active only for traffic from port 80 of
#                               address 10.5.5.5
# Multiple RULE fields per one config file are allowed. For example:
# RULE=10.1.1.2:80
# RULE=10.1.1.2:25
# RULE=10.1.1.2:110
# 
# *** ATTENTION!!!
# All shapers do work only for outgoing traffic!
# So, if you want to build bidirectional shaper you must set it up for
# both ethernet card. For example let's build shaper for our linux box like:
# 
#                     ---------             192.168.1.1
# BACKBONE -----eth0-|  linux  |-eth1------*[our client]
#                     ---------
# 
# Let all traffic from backbone to client will be shaped at 28Kbit and
# traffic from client to backbone - at 128Kbit. We need two config files:
# 
# ---8<-----/etc/sysconfig/cbq/cbq-28.client-out----
# DEVICE=eth1,10Mbit,1Mbit
# RATE=28Kbit
# WEIGHT=2Kbit
# PRIO=5
# RULE=192.168.1.1
# ---8<---------------------------------------------
# 
# ---8<-----/etc/sysconfig/cbq/cbq-128.client-in----
# DEVICE=eth0,10Mbit,1Mbit
# RATE=128Kbit
# WEIGHT=10Kbit
# PRIO=5
# RULE=192.168.1.1,
# ---8<---------------------------------------------
#                 ^pay attention to "," - this is source address!
# 
# Enjoy.
