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=20
first class less bandwdith, use the fw filter to catch the marked packets=
 and=20
put them in the first class, use a second filter (or in case of htb, make=
 the=20
second class the default class) to put all other packets in the second cl=
ass.
If you do that, you can control the traffic of the user like you want.  Y=
ou=20
can even let it use all available bandwidth, but if someone else wants to=
 do=20
it, he has to wait.

More info about shaping can be found on www.lartc.org and www.docum.org. =
 You=20
need the fw fitler and cbq or htb to create the qdisc and classes.
