Здравейте! Налага ми се да споделям интернет с още един компютър - интернета е със скорос 1Mbit/s. Опитвам се да пусна някакъв шейпър за да го разпределя. Интернета от доставчика ми едва на eth0, а другият компйтър е вързан на eth1. Порових се малко и забелязах, чи по подразбиране има инсталиран шейпър CBQ. Опитах се да си направя едно конфигурационно файлче и сега то изглежда по следния начин:
Примерен код

DEVICE=eth1,10Mbit,1Mbit
RATE=28Kbit
WEIGHT=2Kbit
PRIO=5
RULE=192.168.1.5

Не знам дали трябва де е така, но като се опитам да го пусна ми излиза следното:
Примерен код

root@bashi-desktop:/home/bashi# /etc/init.d/shaper start
Starting CBQ traffic shaping: RTNETLINK answers: No such file or directory
shaper.

Това какво означава - че е пуснат или не шейпъра?
Пробвах да сменя името на конфигурационния файл -сега е cbq-shaper.opit и по подразбиране е в /etc/shaper.
Ето сега какво ми дава:
Примерен код
root@bashi-desktop:/etc/shaper# /etc/init.d/shaper start
Starting CBQ traffic shaping: RTNETLINK answers: No such file or directory
RTNETLINK answers: No such file or directory
RTNETLINK answers: No such file or directory
RTNETLINK answers: No such file or directory

Другото - аз съм вързан към една локална мрежа 10.0.0.0 към която съм дал достъп на 192.168.1.5 - echo 1 > /proc/sys/net/ipv4/ip_forward?

#       not checked, first match is taken. Midnight wrap (eg. 20:00-6:00)
#       is allowed and taken care of.
# v0.3a4- fixed small bug in IF operator. Thanks to
#     Rafal Maszkowski <rzm at icm.edu.pl>

# v0.3a - added TIME parameter. Example: TIME=00:00-19:00;64Kbit/6Kbit
#     So, between 00:00 and 19:00 the RATE will be 64Kbit.
#     Just start "cbq.init timecheck" periodically from cron
#     (every 10 minutes for example). DON'T FORGET though, to run
#     "cbq.init start" for CBQ to initialize.
# v0.2  - Some cosmetic changes. Now it is more compatible with old bash
#     version. Thanks to Stanislav V. Voronyi <stas at 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 script is meant to simplify setup and management of relatively simple
# CBQ-based traffic control on Linux. Access to advanced networking features
# of Linux kernel is provided by "ip" and "tc" utilities from A. Kuznetsov's
# iproute2 package, available at ftp://ftp.inr.ac.ru/ip-routing. Because the
# utilities serve primarily to translate user wishes to RTNETLINK commands,
# their interface is rather spartan, intolerant and requires quite a lot of
# typing. And typing is what this script attempts to reduce :)
#
# The advanced networking stuff in Linux is pretty flexible and this script
# aims to bring some of its features to the not-so-hard-core Linux users. Of
# course, there is a tradeoff between simplicity and flexibility and you may
# realize that the flexibility suffered too much for your needs -- time to
# face "ip" and "tc" interface.
#
# To speed up the "start" command, simple caching was introduced in version
# 0.6.4. The caching works so that the sequence of "tc" commands for given
# configuration is stored in a file (/var/cache/cbq.init by default) which
# is used next time the "start" command is run to avoid repeated parsing of
# configuration files. This cache is invalidated whenever any of the CBQ
# configuration files changes. If you want to run "shaper start" without
# caching, run it as "shaper start nocache". If you want to force cache
# invalidation, run it as "shaper start invalidate". Caching is disabled
# if you have logging enabled (ie. CBQ_DEBUG is not empty).
#
# If you only want cqb.init to translate your configuration to "tc" commands,
# use "compile" command which will output "tc" commands required to build
# your configuration. Bear in mind that "compile" does not check if the "tc"
# commands were successful - this is done (in certain places) only when the
# "start nocache" command is used, which is also useful when creating the
# configuration to check whether it is completely valid.
#
# All CBQ parameters are valid for Ethernet interfaces only, The script was
# tested on various Linux kernel versions from series 2.1 to 2.4 and several
# distributions with KSI Linux (Nostromo version) as the premier one.
#
#
# HOW DOES IT WORK?
# -----------------
#
# Every traffic class must be described by a file in the $CBQ_PATH directory
# (/etc/shaper by default) - one file per class.
#
# The config file names must obey mandatory format: cbq-<clsid>.<name> where
# <clsid> is two-byte hexadecimal number in range <0002-FFFF> (which in fact
# is a CBQ class ID) and <name> is the name of the class -- anything to help
# you distinguish the configuration files. For small amount of classes it is
# often possible (and convenient) to let <clsid> resemble bandwidth of the
# class.
#
# Example of valid config name:
#   cbq-1280.My_first_shaper
#
#
# The configuration file may contain the following parameters:
#
### Device parameters
#
# DEVICE=<ifname>,<bandwidth>[,<weight>]   mandatory
# DEVICE=eth0,10Mbit,1Mbit
#
#   <ifname> is the name of the interface you want to control
#      traffic on, e.g. eth0
#   <bandwidth> is the physical bandwidth of the device, e.g. for
#      ethernet 10Mbit or 100Mbit, for arcnet 2Mbit
#   <weight> is tuning parameter that should be proportional to
#      <bandwidth>. As a rule of thumb: <weight> = <bandwidth> / 10
#
# When you have more classes on one interface, it is enough to specify
# <bandwidth> [and <weight>] only once, therefore in other files you only
# need to set DEVICE=<ifname>.
#
### Class parameters
#
# RATE=<speed>               mandatory
# RATE=5Mbit
#
#   Bandwidth allocated to the class. Traffic going through the class is
#   shaped to conform to specified rate. You can use Kbit, Mbit or bps,
#   Kbps and Mbps as suffices. If you don't specify any unit, bits/sec
#   are used. Also note that "bps" means "bytes per second", not bits.
#
# WEIGHT=<speed>             mandatory
# WEIGHT=500Kbit
#
#   Tuning parameter that should be proportional to RATE. As a rule
#   of thumb, use WEIGHT ~= RATE / 10.
#
# PRIO=<1-8>               optional, default 5
# PRIO=5
#
#   Priority of class traffic. The higher the number, the lesser
#   the priority. Priority of 5 is just fine.
#
# PARENT=<clsid>            optional, default not set
# PARENT=1280
#
#   Specifies ID of the parent class to which you want this class be
#   attached. You might want to use LEAF=none for the parent class as
#   mentioned below. By using this parameter and carefully ordering the
#   configuration files, it is possible to create simple hierarchical
#   structures of CBQ classes. The ordering is important so that parent
#   classes are constructed prior to their children.
#
# LEAF=none|tbf|sfq            optional, default "tbf"
#
#   Tells the script to attach specified leaf queueing discipline to CBQ
#   class. By default, TBF is used. Note that attaching TBF to CBQ class
#   shapes the traffic to conform to TBF parameters and prevents the class
#   from borrowing bandwidth from its parent even if you have BOUNDED set
#   to "no". To allow the class to borrow bandwith (provided it is not
#   bounded), you must set LEAF to "none" or "sfq".
#
#   If you want to ensure (approximately) fair sharing of bandwidth among
#   several hosts in the same class, you might want to specify LEAF=sfq to
#   attach SFQ as leaf queueing discipline to that class.
#
# BOUNDED=yes|no            optional, default "yes"
#
#   If set to "yes", the class is not allowed to borrow bandwidth from
#   its parent class in overlimit situation. If set to "no", the class
#   will be allowed to borrow bandwidth from its parent.
#
# Note:   Don't forget to set LEAF to "none" or "sfq", otherwise the class will
#   have TBF attached to itself and will not be able to borrow unused
#   bandwith from its parent.
#
# ISOLATED=yes|no            optional, default "no"
#
#   If set to "yes", the class will not lend unused bandwidth to
#   its children.
#
### TBF qdisc parameters
#
# BUFFER=<bytes>[/<bytes>]         optional, default "10Kb/8"
#
#   This parameter controls the depth of the token bucket. In other
#   words it represents the maximal burst size the class can send.
#   The optional part of parameter is used to determine the length
#   of intervals in packet sizes, for which the transmission times
#   are kept.
#
# LIMIT=<bytes>               optional, default "15Kb"
#
#   This parameter determines the maximal length of backlog. If
#   the queue contains more data than specified by LIMIT, the
#   newly arriving packets are dropped. The length of backlog
#   determines queue latency in case of congestion.
#
# PEAK=<speed>               optional, default not set
#
#   Maximal peak rate for short-term burst traffic. This allows you
#   to control the absolute peak rate the class can send at, because
#   single TBF that allows 256Kbit/s would of course allow rate of
#   512Kbit for half a second or 1Mbit for a quarter of second.
#
# MTU=<bytes>                 optional, default "1500"
#
#   Maximum number of bytes that can be sent at once over the
#   physical medium. This parameter is required when you specify
#   PEAK parameter. It defaults to MTU of ethernet - for other
#   media types you might want to change it.
#
# Note: Setting TBF as leaf qdisc will effectively prevent the class from
#   borrowing bandwidth from the ancestor class, because even if the
#   class allows more traffic to pass through, it is then shaped to
#   conform to TBF.
#
### SFQ qdisc parameters
#
# The SFQ queueing discipline is a cheap way for sharing class bandwidth
# among several hosts. As it is stochastic, the fairness is approximate but
# it will do the job in most cases. If you want real fairness, you should
# probably use WRR (weighted round robin) or WFQ queueing disciplines. Note
# that SFQ does not do any traffic shaping - the shaping is done by the CBQ
# class the SFQ is attached to.
#
# QUANTUM=<bytes>            optional, default not set
#
#   This parameter should not be set lower than link MTU, for ethernet
#   it is 1500b, or (with MAC header) 1514b which is the value used
#   in Alexey Kuznetsov's examples.
#
# PERTURB=<seconds>            optional, default "10"
#
#   Period of hash function perturbation. If unset, hash reconfiguration
#   will never take place which is what you probably don't want. The
#   default value of 10 seconds is probably a good one.
#
### Filter parameters
#
# RULE=[[saddr[/prefix]][:port[/mask]],][daddr[/prefix]][:port[/mask]]
#
#   These parameters make up "u32" filter rules that select traffic for
#   each of the classes. You can use multiple RULE fields per config.
#
#   The optional port mask should only be used by advanced users who
#   understand how the u32 filter works.
#
# Some examples:
#
#   RULE=10.1.1.0/24:80
#      selects traffic going to port 80 in network 10.1.1.0
#
#   RULE=10.2.2.5
#      selects traffic going to any port on single host 10.2.2.5
#
#   RULE=10.2.2.5:20/0xfffe
#      selects traffic going to ports 20 and 21 on host 10.2.2.5
#
#   RULE=:25,10.2.2.128/26:5000
#      selects traffic going from anywhere on port 50 to
#      port 5000 in network 10.2.2.128
#
#   RULE=10.5.5.5:80,
#      selects traffic going from port 80 of single host 10.5.5.5
#
#
#
# REALM=[srealm,][drealm]
#
#   These parameters make up "route" filter rules that classify traffic
#   according to packet source/destination realms. For information about
#   realms, see Alexey Kuznetsov's IP Command Reference. This script
#   does not define any realms, it justs builds "tc filter" commands
#   for you if you need to classify traffic this way.
#
#   Realm is either a decimal number or a string referencing entry in
#   /etc/iproute2/rt_realms (usually).
#
# Some examples:
#
#   REALM=russia,internet
#      selects traffic going from realm "russia" to realm "internet"
#
#   REALM=freenet,
#      selects traffic going from realm "freenet"
#
#   REALM=10
#      selects traffic going to realm 10
#
#
#
# MARK=<mark>
#
#   These parameters make up "fw" filter rules that select traffic for
#   each of the classes accoring to firewall "mark". Mark is a decimal
#   number packets are tagged with if firewall rules say so. You can
#   use multiple MARK fields per config.
#
#
# Note: Rules for different filter types can be combined. Attention must be
#   paid to the priority of filter rules, which can be set below using
#   PRIO_{RULE,MARK,REALM} variables.
#
### Time ranging parameters
#
# TIME=[<dow>,<dow>, ...,<dow>/]<from>-<till>;<rate>/<weight>[/<peak>]
# TIME=0,1,2,5/18:00-06:00;256Kbit/25Kbit
# TIME=60123/18:00-06:00;256Kbit/25Kbit
# TIME=18:00-06:00;256Kbit/25Kbit
#
#   This parameter allows you to differentiate the class bandwidth
#   throughout the day. You can specify multiple TIME parameters, if
#   the times overlap, last match is taken. The fields <rate>, <weight>
#   and <peak> correspond to parameters RATE, WEIGHT and PEAK (which
#   is optional and applies to TBF leaf qdisc only).
#
#   You can also specify days of week when the TIME rule applies. <dow>
#   is numeric, 0 corresponds to sunday, 1 corresponds to monday, etc.
#
###
#
# Sample configuration file: cbq-1280.My_first_shaper
#
# --------------------------------------------------------------------------
# DEVICE=eth0,10Mbit,1Mbit
# RATE=128Kbit
# WEIGHT=10Kbit
# PRIO=5
# RULE=192.128.1.0/24
# --------------------------------------------------------------------------
#
# The configuration says that we will control traffic on 10Mbit ethernet
# device eth0 and the traffic going to network 192.168.1.0 will be
# processed with priority 5 and shaped to rate of 128Kbit.
#
# Note that you can control outgoing traffic only. If you want to control
# traffic in both directions, you must set up CBQ for both interfaces.
#
# Consider the following example:
#
#                    +---------+      192.168.1.1
# BACKBONE -----eth0-|  linux  |-eth1------*-[client]
#                    +---------+
#
# Imagine you want to shape traffic from backbone to the client to 28Kbit
# and traffic in the opposite direction to 128Kbit. You need to setup CBQ
# on both eth0 and eth1 interfaces, thus you need two config files:
#
# cbq-028.backbone-client
# --------------------------------------------------------------------------
# DEVICE=eth1,10Mbit,1Mbit
# RATE=28Kbit
# WEIGHT=2Kbit
# PRIO=5
# RULE=192.168.1.1
# --------------------------------------------------------------------------
#
# cbq-128.client-backbone
# --------------------------------------------------------------------------
# DEVICE=eth0,10Mbit,1Mbit
# RATE=128Kbit
# WEIGHT=10Kbit
# PRIO=5
# RULE=192.168.1.1,
# --------------------------------------------------------------------------
#
# Pay attention to comma "," in the RULE field - it denotes source address!
#
# Enjoy.

Името на файла трябва да във формат

cbq-0002.My_first_shaper

cbq-0003.My_first_shaper

cbq-0004.My_first_shaper

и да са разположени в папката /etc/shaper

След това име сложих и едно .shaper и уж стана. Пуснах пинг от второто PC и той стигна за около 1500 ms но после се оправи и тръгна нормално. Като отварям сайтовете за сега ги отваря много бавно но не знам дали ще работи и за в бъдеще. Другия ми въпрос е има ли начин към тази мрежа 10.0.0.0 да се сложи друго ограничение понеже тя е локална и доста бърза?

Kak няма да ти бави като си го направил да ти ограничава на 28Кbit/s
ако теглиш нещо при това ограничение и в същия момент пуснеш пинг не 1500 ms, а 4 секунди време ще ти покаже
Четете малко преди да започнете да правите нещо
Прочети ги малко тези закоментиранете редове във файла /etc/init.d/shaper

Така по въпроса за 10-та мрежа според мен може да стане така (ако някъде греша сигурно ще ме поправят пичовете)

Твоя рутер трябва да има 2 вътрешни интерфейса с IP:
192.168.1.1 и 192.168.10.1 така клиента ти също трябва да има 2 IP-та пример 192.168.1.5 и 192.168.10.5

На рутера правиш път до 10.0.0.0 САМО от мрежа 192.168.10.0/24
а към интернета правиш път само от мрежа 192.168.1.0/24
И съответно налагаш по-голямо ограничените на 192.168.10.5 и по-малко ограничение на 192.168.1.5

И аз така си мислех, обаче е малко неудобно, защото двете мрежи се ползват едновременно.
