Hi all,
that is yet another problem I can't solve.
I want to use the iptables to match the packets to be queued but do not know
how to tell my tc queues wich marked packages to use.
EXAMPLE:
ppp0 with (768Kbit downstream and 128Kbit upstream)
the privileges local port 27005 should get 512/96
# the marked packets below shall be privileged.
$IPTABLES -t mangle -A PREROUTING -o ppp0 -p udp --sport 27005 \
-j MARK --set-mark 21
$IPTABLES -t mangle -A POSTROUTING -i ppp0 -p udp --dport 27005 \
-j MARK --set-mark 22
# the other packets may get the remaining bandwidth
# attach cbq to device ppp0 with handle 1: (1:0 ?)
$TC qdisc add dev ppp0 root handle 1: cbq bandwidth 768Kbit avpkt mpu 64
# create the root class (1:1)
$TC class add dev ppp0 parent 1:0 classid :1 est 1sec 4sec cbq \
bandwidth 768Kbit rate 768Kbit
# create class A (privileged 1:10)
$TC class add dev ppp0 parent 1:1 classid 1:10 est 1sec 4sec cbq \
bandwidth 768Kbit rate 512Kbit allot 1514 maxburst 50 avpkt 1000
$TC qdisc add dev ppp0 parent 1:10 sfq quantum 1514b perturb 15
# create class B (the remaining 1:20)
$TC class add dev ppp0 parent 1:1 class 1:20 est 1sec 4sec cbq \
bandwidth 768Kbit rate 256Kbit allot 1514 maxburst 50 avpkt 1000
$TC qdisc add dev ppp0 parent 1:20 sfq quantum 1514b perturb 15
END EXAMPLE.
So. But how do I tell TC to use the iptables marked packets to queue?
Many many thanks,
Christian.
