[LARTC] shaping marked packets

[LARTC] shaping marked packets

[Axel Loewe]

hi,

i want to decrease the upload-bandwith used by a user with the uid xyz
(only one programm running under this user), so i mark the packets with
iptables by adding the following rule:
iptables -A OUTPUT -t mangle -m owner --uid-owner xxx -j MARK --set-mark 1
now my problem is what to do after this ;) catch all the packets in an
extra table but what then? to me it doesn't matter wheter to use cbq or
htb, but htb seems easier to me ;) how do i add a qdisc that only
applies to the packets in this special table?

greets axel

p.s. sorry for my poor english

Add a qdisc, add 2 classes (one for the user and one for the rest), give the 
first class less bandwdith, use the fw filter to catch the marked packets and 
put them in the first class, use a second filter (or in case of htb, make the 
second class the default class) to put all other packets in the second class.
If you do that, you can control the traffic of the user like you want.  You 
can even let it use all available bandwidth, but if someone else wants to do 
it, he has to wait.

More info about shaping can be found on www.lartc.org and www.docum.org.  You 
need the fw fitler and cbq or htb to create the qdisc and classes.

[LARTC] shaping marked packets

[nix4me]

Hi,
 
I am trying to figure out how to shape the following marked packets and 
limit them to a speed on 30KBytes.  I have read the documentation but I 
am unsue of what to do.

iptables -t mangle -A FTP-OUT -p tcp --dport 50000:51000 -j MARK 
--set-mark 1
 
Mark

tc qdisc del dev ethx root
tc qdisc add dev ethx root handle 1: htb
tc class add dev ethx parent 1: classid 1:1 htb rate 30kbps
tc filter add dev ethx parent 1:  prio 0 protocol ip handle 1 fw flowid 1:1
