Hi,
I am tryin to shape my routers traffic ..I
have read lartc document .HTB is suggested there .So I used htb ..My kernel is
2.4.18 .I patched my kernel and activated the supports ..
I have created my classes as follows
tc qdisc add dev eth2 root handle 1: htb default 14
tc class add dev eth2 parent 1: classid 1:1 htb rate 2mbit ceil 2mbit tc class add dev eth2 parent 1:1 classid 1:10 htb rate 700kbit ceil 1700kbit tc class add dev eth2 parent 1:1 classid 1:11 htb rate 200kbit ceil 1250kbit tc class add dev eth2 parent 1:1 classid 1:12 htb rate 600kbit ceil 1700kbit tc class add dev eth2 parent 1:1 classid 1:13 htb rate 200kbit ceil 1700kbit tc class add dev eth2 parent 1:1 classid 1:14 htb rate 300kbit ceil 1700kbit tc qdisc add dev eth2 parent 1:10 handle 10: sfq perturb
10
tc qdisc add dev eth2 parent 1:11 handle 20: sfq perturb 10 tc qdisc add dev eth2 parent 1:12 handle 30: sfq perturb 10 tc qdisc add dev eth2 parent 1:13 handle 40: sfq perturb 10 tc qdisc add dev eth2 parent 1:14 handle 50: sfq perturb 10 tc filter add dev eth2 protocol ip parent 1:0 prio 1 u32
match ip dst 194.x.x.254 match ip sport 80 0xffff flowid 1:10
tc filter add dev eth2 protocol ip parent 1:0 prio 1 u32 match ip dst 194.x.x.254 flowid 1:11 tc filter add dev eth2 protocol ip parent 1:0 prio 1 u32 match ip dst 194.x.x.250 flowid 1:12 tc filter add dev eth2 protocol ip parent 1:0 prio 1 u32 match ip dst 194.x.x.200 flowid 1:13 At the begining every thing works fine ..But when overlimits
begins to occur the class having overlimits hangs the traffic related to that
class
I have got error messages in syslog as follows

What can the problem be ?
