   1 # CHANGES
   2 # -------
   3 # v0.3a2- fixed bug in "if" operator. Thanks kad@dgtu.donetsk.ua.
   4 # v0.3a-  added TIME parameter. Example:
   5 #         TIME=00:00-19:00;64Kbit/6Kbit
   6 #         So, between 00:00 and 19:00 RATE will be 64Kbit.
   7 #         Just start "cbq.init timecheck" periodically from cron (every 10
   8 #         minutes for example).
   9 #         !!! Anyway you MUST start "cbq.init start" for CBQ initialize.
  10 # v0.2 -  Some cosmetique changes. Now it more compatible with
  11 #         old bash version. Thanks to Stanislav V. Voronyi
  12 #         <stas@cnti.uanet.kharkov.ua>.
  13 # v0.1 -  First public release

  15 # README
  16 # ------
  17 #
  18 # First of all - this is just a SIMPLE EXAMPLE of CBQ power.
  19 # Don't ask me "why" and "how" :)
  20 #
  21 # This is an example of using CBQ (Class Based Queueing) and policy-based
  22 # filter for building smart ethernet shapers. All CBQ parameters are
  23 # correct only for ETHERNET (eth0,1,2..) linux interfaces. It works for
  24 # ARCNET too (just set bandwidth parameter to 2Mbit). It was tested
  25 # on 2.1.125-2.1.129 linux kernels (KSI linux, Nostromo version) and
  26 # ip-route utility by A.Kuznetsov (iproute2-ss981101 version).
  27 # You can download ip-route from ftp://ftp.inr.ac.ru/ip-routing or
  28 # get iproute2*.rpm (compiled with glibc) from ftp.ksi-linux.com.
  29 #
  30 #
  31 # HOW IT WORKS
  32 #
  33 # Each shaper must be described by config file in $CBQ_PATH
  34 # (/etc/sysconfig/cbq/) directory - one config file for each CBQ shaper.
  35 #
  36 # Some words about config file name:
  37 # Each shaper has its personal ID - two byte HEX number. Really ID is
  38 # CBQ class.
  39 # So, filename looks like:
  40 #
  41 # cbq-1280.My_first_shaper
  42 # ^^^ ^^^  ^^^^^^^^^^^^^
  43 #  |  |            |______ Shaper name - any word
  44 #  |  |___________________ ID (0000-FFFF), let ID looks like shaper's rate
  45 #  |______________________ Filename must begin from "cbq-"
  46 #
  47 #
  48 # Config file describes shaper parameters and source[destination]
  49 # address[port].
  50 # For example let's prepare /etc/sysconfig/cbq/cbq-1280.My_first_shaper:
  51 #
  52 # ----------8<---------------------
  53 # DEVICE=eth0,10Mbit,1Mbit
  54 # RATE=128Kbit
  55 # WEIGHT=10Kbit
  56 # PRIO=5
  57 # RULE=192.168.1.0/24
  58 # ----------8<---------------------
  59 #
  60 # This is minimal configuration, where:
  61 # DEVICE:  eth0   - device where we do control our traffic
  62 #          10Mbit - REAL ethernet card bandwidth
  63 #          1Mbit  - "weight" of :1 class (parent for all shapers for eth0),
  64 #                   as a rule of thumb weight=batdwidth/10.
  65 #          100Mbit adapter's example: DEVICE=eth0,100Mbit,10Mbit
  66 #          *** If you want to build more than one shaper per device it's
  67 #              enough to describe bandwidth and weight once  - cbq.init
  68 #              is smart :) You can put only 'DEVICE=eth0' into cbq-*
  69 #              config file for eth0.
  70 #
  71 # RATE:    Shaper's speed - Kbit,Mbit or bps (bytes per second)
  72 #
  73 # WEIGHT:  "weight" of shaper (CBQ class). Like for DEVICE - approx. RATE/10
  74 #
  75 # PRIO:    shaper's priority from 1 to 8 where 1 is the highest one.
  76 #          I do always use "5" for all my shapers.
  77 #
  78 # RULE:    [source addr][:source port],[dest addr][:dest port]
  79 #          Some examples:
  80 # RULE=10.1.1.0/24:80         - all traffic for network 10.1.1.0 to port 80
  81 #                               will be shaped.
  82 # RULE=10.2.2.5               - shaper works only for IP address 10.2.2.5
  83 # RULE=:25,10.2.2.128/25:5000 - all traffic from any address and port 25 to
  84 #                               address 10.2.2.128 - 10.2.2.255 and port 5000
  85 #                               will be shaped.
  86 # RULE=10.5.5.5:80,           - shaper active only for traffic from port 80 of
  87 #                               address 10.5.5.5
  88 # Multiple RULE fields per one config file are allowed. For example:
  89 # RULE=10.1.1.2:80
  90 # RULE=10.1.1.2:25
  91 # RULE=10.1.1.2:110
  92 #
  93 # *** ATTENTION!!!
  94 # All shapers do work only for outgoing traffic!
  95 # So, if you want to build bidirectional shaper you must set it up for
  96 # both ethernet card. For example let's build shaper for our linux box like:
  97 #
  98 #                     ---------             192.168.1.1
  99 # BACKBONE -----eth0-|  linux  |-eth1------*[our client]
 100 #                     ---------
 101 #
 102 # Let all traffic from backbone to client will be shaped at 28Kbit and
 103 # traffic from client to backbone - at 128Kbit. We need two config files:
 104 #
 105 # ---8<-----/etc/sysconfig/cbq/cbq-28.client-out----
 106 # DEVICE=eth1,10Mbit,1Mbit
 107 # RATE=28Kbit
 108 # WEIGHT=2Kbit
 109 # PRIO=5
 110 # RULE=192.168.1.1
 111 # ---8<---------------------------------------------
 112 #
 113 # ---8<-----/etc/sysconfig/cbq/cbq-128.client-in----
 114 # DEVICE=eth0,10Mbit,1Mbit
 115 # RATE=128Kbit
 116 # WEIGHT=10Kbit
 117 # PRIO=5
 118 # RULE=192.168.1.1,
 119 # ---8<---------------------------------------------
 120 #                 ^pay attention to "," - this is source address!
 121 #
 122 # Enjoy.
