Hi!
I am trying to prioritize udp traffic to satisfy our gamers.
The setup is
800 users
/ 8 Mbit fiber (eth3)
LAN (eth0) - FW -
\ 6 Mbit FWA (eth2)
The 8 Mbit is the default gw and the FWA is currently only used by our proxy
server
I am using this script:
$IP rule add fwmark 1 table 100 pref 1000
$IP route add table 200 scope global nexthop via 213.173.228.1 dev eth2
tc filter del dev eth0 prio 3
tc qdisc del dev eth0 root handle 1:
tc qdisc add dev eth0 root handle 1: htb default 12
tc class add dev eth0 parent 1: classid 1:1 htb rate 10Mbit ceil 14Mbit
burst 2k
# Class for UDP, ICMP, ssh traffic
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 1MBit ceil 4Mbit
burst 2k prio 0
# Class for all traffic to our servers
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 3Mbit ceil 10Mbit
burst 2k prio 1
# All other traffic
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 6Mbit ceil 8Mbit
burst 2k prio 3
tc qdisc add dev eth0 parent 1:10 handle 20: sfq perturb 10
tc qdisc add dev eth0 parent 1:11 handle 30: sfq perturb 10
tc qdisc add dev eth0 parent 1:12 handle 40: sfq perturb 10
tc filter add dev eth0 parent 1: protocol ip prio 3 handle 4 fw flowid 1:10
tc filter add dev eth0 parent 1: protocol ip prio 3 handle 5 fw flowid 1:11
iptables -t mangle -A PREROUTING -i eth0 -p udp -j MARK --set-mark 4
iptables -t mangle -A PREROUTING -i eth0 -p tcp --dport 22 -j MARK
--set-mark 4
iptables -t mangle -A PREROUTING -s 10.10.10.3 -i eth0 -j MARK --set-mark 5
iptables -t mangle -A PREROUTING -s 10.10.10.4 -i eth0 -j MARK --set-mark 5
iptables -t mangle -A PREROUTING -s 10.10.10.5 -i eth0 -j MARK --set-mark 5
iptables -t mangle -A PREROUTING -s 10.10.10.12 -j MARK --set-mark 2
The problem is that the all the traffic is going to the default class no
matter what I do.
I can see that the counters in "iptables -t mangle -L -v -n" is
counting up,
but the counters in "tc -s class ls dev eth0" is not.
I have also tried not to use fwmark but added the rules directly with "tc
filter...", but with same results...
Have I forgotten something, or what is the problem?

Default kwyword must point to leaf or be 0 (so unclassified packets go thru directly). If you want to "direct" other packets to non-leaf do it by catch all filter with the largest "pref".

I worked with 2.4.20.By some sort of accident I found the cause for the "problem" (here at least): Make sure that the attached (to the root in case of HTB) filters actually filters the packets to the leaves (leafs?) in the (pseudo-)tree. Then, if filters are correctly designed, no traffic will go to HTB default. -- Mvh. / Best regards, Steen Suder <http://www.suder.dk/> ICQ UIN 4133803 _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
