Hi fellows, i'm just a newbie to use the cool tc and played around the last 2 weeks. I'm quite confident - in theory - what's possible and the basic difference between the queuing disciplines. We're using a Fedora Core 3 box as Gateway (iptables,tc,iproute2 with NAT). Clients are coming in via eth1 and outgouing traffic (2Mbit/s SDSL) through eth0. So we would like to enable bandwidth limitation per-user, so i just used several scripts (htp from sourceforge,cbq.init ,wondershaper etc). (Each client: Downstream max 128kbit/s, Upstream max 90kbit/s) Shaping is working fine if i mark this specific source with a iptables rule, but as soon i apply multiple different source ip's to mark it within the same queue, all are sharing my limitation and i thought each of them will get the rate-limiting. Example firewall rule: $IPTABLES -t mangle -A FORWARD -s ! 10.0.0.30 -d 10.0.0.30 -j MARK --set-mark 1 #downstream $IPTABLES -t mangle -A FORWARD -s 10.0.0.30 -j MARK --set-mark 2 #upstream I also tried the u23 matching within tc, but same effect, i'm also not sure if i can use this kind of matching in a nat environment ? I'm really done, no ideas what i'm doing wrong ! BTW: Anyone using tcng on FC3 and kernel 2.6x :-) My tc output: ************* ### eth0: queueing disciplines qdisc cbq 1: rate 2Mbit (bounded,isolated) prio no-transmit qdisc tbf 90: parent 1:90 rate 90Kbit burst 10Kb lat 444.4ms ### eth0: traffic classes class cbq 1: root rate 2Mbit (bounded,isolated) prio no-transmit class cbq 1:90 parent 1: leaf 90: rate 90Kbit (bounded) prio 5 class tbf 90:1 parent 90: ### eth0: filtering rules filter parent 1: protocol ip pref 200 fw filter parent 1: protocol ip pref 200 fw handle 0x2 classid 1:90 ### eth1: queueing disciplines qdisc cbq 1: rate 10Mbit (bounded,isolated) prio no-transmit qdisc tbf 128: parent 1:128 rate 128Kbit burst 10Kb lat 312.5ms ### eth1: traffic classes class cbq 1: root rate 10Mbit (bounded,isolated) prio no-transmit class cbq 1:128 parent 1: leaf 128: rate 128Kbit (bounded) prio 5 class tbf 128:1 parent 128: ### eth1: filtering rules filter parent 1: protocol ip pref 200 fw filter parent 1: protocol ip pref 200 fw handle 0x1 classid 1:128 ### eth2: queueing disciplines qdisc pfifo_fast 0: bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 THANKS for any hints Cheers Geri _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
