More - less it looks like this : ------------------------CUT------------------------------------------------------ #root qdisc and class for eth1 $tc qdisc add dev eth1 root handle 1:0 htb default 19 $tc class add dev eth1 parent 1:0 classid 1:1 htp ratel ${CEIL_UP}kbit ceil ${CEIL_UP}kbit #classes, qdiscs and filters for services $tc class add dev eth1 parent 1:1 classid 1:11 htb rate 90kbit ceil 150kbit prio 0 $tc class add dev eth1 parent 1:1 classid 1:12 htb rate 100kbit ceil 250kbit prio 0 $tc class add dev eth1 parent 1:1 classid 1:13 htb rate 90kbit ceil 1250kbit prio 2 $tc qdisc add dev eth1 parent 1:11 handle 111: sfq perturb 10 # $tc qdisc add dev eth1 parent 1:11 handle 112: sfq perturb 10 # Typical $tc qdisc add dev eth1 parent 1:11 handle 113: sfq perturb 10 # $tc filter add dev eth1 parent 1:0 protocol ip prio 0 handle 1 fw classid 1:11 $tc filter add dev eth1 parent 1:0 protocol ip prio 0 handle 1 fw classid 1:12 $tc filter add dev eth1 parent 1:0 protocol ip prio 2 handle 1 fw classid 1:13 the same thing goes for imq #root qdisc and class for imq0 $tc qdisc add dev imq0 root handle 2:0 htb default 29 $tc class add dev imq0 parent 2:0 classid 2:1 htp ratel ${CEIL_DN}kbit ceil ${CEIL_DN}kbit #classes, qdiscs and filters for services $tc class add dev imq0 parent 2:1 classid 2:21 htb rate 90kbit ceil 150kbit prio 0 $tc class add dev imq0 parent 2:1 classid 2:22 htb rate 100kbit ceil 250kbit prio 0 $tc class add dev imq0 parent 2:1 classid 2:23 htb rate 90kbit ceil 1250kbit prio 2 $tc qdisc add dev imq0 parent 2:11 handle 211: sfq perturb 10 # $tc qdisc add dev imq0 parent 2:11 handle 212: sfq perturb 10 # $tc qdisc add dev imq0 parent 2:11 handle 213: sfq perturb 10 # $tc filter add dev imq0 parent 2:0 protocol ip prio 0 handle 0xb fw classid 2:21 $tc filter add dev imq0 parent 2:0 protocol ip prio 0 handle 0xc fw classid 2:22 $tc filter add dev imq0 parent 2:0 protocol ip prio 2 handle 0xd fw classid 2:23 -----------------------CUT-------------------------------------------------------------------------------- There are more of these classes - up to 19 (or 29 on imq0). When I stat classes and qdiscs everything looks fine : traffic goes smoothly through every class. Class 1:11 , and 2:21 are for icmp packets only. The problem is - when I try to download some large file using http which goes through 1:13 and 2:23 classes pings rise to very high values (~350 - 600 , while normally it should be something ~5-25 ms). The situation is getting much worse when I allow p2p traffic (1:15, 2:25) to pass through. Although schedulers seem to work ,because I can browse web pages, the whole interactivity is lost and output (and input) bandwidth is consumed almost totally. my system is : 2.4.29-ow1 , additional schedulers : esfq and wrr p2p packets are `intercepted' by p2p and ipp2p modules. Other packets are marked this way : --------------CUT-------------------- $IPTABLES -A PREROUTING -t mangle -i eth1 -j IMQ --todev 0 [...] $IPTABLES -A PREROUTING -t mangle -i eth1 -p icmp -j MARK --set-mark 0xb $IPTABLES -A POSTROUTING -t mangle -o eth1 -p icmp -j MARK --set-mark 0x1 [...] $IPTABLES -A PREROUTING -t mangle -i eth1 -m multiport --sport 80,443 -j MARK --set-mark 0xd $IPTABLES -A POSTROUTING -t mangle -o eth1 -m multiport --dport 80,443 -j MARK --set-mark 0x3 [....] -------------CUT---------------------------- any idea what might be wrong ? thanks in advance Wlodek _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
