Blank <antifreeze at users.sourceforge.net> # - replace hardcoded ip/tc location with variables # - Mark Davis <mark.davis at gmx.de> # - allow setting of PRIO_{MARK,RULE,REALM} in class file # - Fernando Sanch <toptnc at users.sourceforge.net> # - allow underscores in interface names # v0.7.2- Paulo Sedrez # - fix time2abs to allow hours with leading zero in TIME rules # - Svetlin Simeonov <zvero at yahoo.com> # - fix cbq_device_list to allow VLAN interfaces # - Mark Davis <mark.davis at gmx.de> # - ignore *~ backup files when looking for classes # - Mike Boyer <boyer at administrative.com> # - fix to allow arguments to be passed to "restart" command # v0.7.1- Lubomir Bulej <pallas at kadan.cz> # - default value for PERTURB # - fixed small bug in RULE parser to correctly parse rules with # identical source and destination fields # - faster initial scanning of DEVICE fields # v0.7 - Lubomir Bulej <pallas at kadan.cz> # - lots of various cleanups and reorganizations; the parsing is now # some 40% faster, but the class ID must be in range 0x0002-0xffff # (again). Because of the number of internal changes and the above # class ID restriction, I bumped the version to 0.7 to indicate # something might have got broken :) # - changed PRIO_{U32,FW,ROUTE} to PRIO_{RULE,MARK,REALM} # for consistency with filter keywords # - exposed "compile" command # - Catalin Petrescu <taz at dntis.ro> # - support for port masks in RULE (u32) filter # - Jordan Vrtanoski <obeliks at mt.net.mk> # - support for week days in TIME rules # v0.6.4- Lubomir Bulej <pallas at kadan.cz> # - added PRIO_* variables to allow easy control of filter priorities # - added caching to speed up CBQ start, the cache is invalidated # whenever any of the configuration files changes # - updated the readme section + some cosmetic fixes # v0.6.3- Lubomir Bulej <pallas at kadan.cz> # - removed setup of (unnecessary) class 1:1 - all classes # now use qdisc's default class 1:0 as their parent # - minor fix in the timecheck branch - classes # without leaf qdisc were not updated # - minor fix to avoid timecheck failure when run # at time with minutes equal to 08 or 09 # - respect CBQ_PATH setting in environment # - made PRIO=5 default, rendering it optional in configs # - added support for route filter, see notes about REALM keyword # - added support for fw filter, see notes about MARK keyword # - added filter display to "list" and "stats" commands # - readme section update + various cosmetic fixes # v0.6.2- Catalin Petrescu <taz at dntis.ro> # - added tunnels interface handling # v0.6.1- Pavel Golubev <pg at ksi-linux.com> # - added sch_prio module loading # (thanks johan at iglo.virtual.or.id for reminding) # - resolved errors resulting from stricter syntax checking in bash2 # - Lubomir Bulej <pallas at kadan.cz> # - various cosmetic fixes # v0.6 - Lubomir Bulej <pallas at kadan.cz> # - attempt to limit number of spawned processes by utilizing # more of sed power (use sed instead of grep+cut) # - simplified TIME parser, using bash builtins # - added initial support for SFQ as leaf qdisc # - reworked the documentation part a little # - incorporated pending patches and ideas submitted by # following people for versions 0.3 into version 0.6 # - Miguel Freitas <miguel at cetuc.puc-rio.br> # - in case of overlapping TIME parameters, the last match is taken # - Juanjo Ciarlante <jjo at mendoza.gov.ar> # - chkconfig tags, list + stats startup parameters # - optional tc & ip command logging (into /var/run/cbq-*) # - Rafal Maszkowski <rzm at icm.edu.pl> # - PEAK parameter for setting TBF's burst peak rate # - fix for many config files (use find instead of ls) # v0.5.1- Lubomir Bulej <pallas at kadan.cz> # - fixed little but serious bug in RULE parser # v0.5 - Lubomir Bulej <pallas at kadan.cz> # - added options PARENT, LEAF, ISOLATED and BOUNDED. This allows # (with some attention to config file ordering) for creating # hierarchical structures of shapers with classes able (or unable) # to borrow bandwidth from their parents. # - class ID check allows hexadecimal numbers # - rewritten & simplified RULE parser # - cosmetic changes to improve readability # - reorganization to avoid duplicate code (timecheck etc.) # - timecheck doesn't check classes without TIME fields anymore # v0.4 - Lubomir Bulej <pallas at kadan.cz> # - small bugfix in RULE parsing code # - simplified configuration parsing code # - several small cosmetic changes # - TIME parameter can be now specified more than once allowing you to # differentiate RATE throughout the whole day. Time overlapping is # 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> # v0.3a3- fixed grep bug when using more than 10 eth devices. Thanks to David # Trcka <trcka at poda.cz>. # v0.3a2- fixed bug in "if" operator. Thanks kad at dgtu.donetsk.ua. # 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 "cbq.init start" without # caching, run it as "cbq.init start nocache". If you want to force cache # invalidation, run it as "cbq.init 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/sysconfig/cbq 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.
