Hi,

I am tryin to shape my routers = traffic ..I=20 have read lartc document .HTB is suggested there .So I used htb ..My = kernel is=20 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=20 class add dev eth2 parent 1: classid 1:1 htb rate 2mbit ceil 2mbit
tc = class=20 add dev eth2 parent 1:1 classid 1:10 htb rate 700kbit ceil = 1700kbit
tc class=20 add dev eth2 parent 1:1 classid 1:11 htb rate 200kbit ceil = 1250kbit
tc class=20 add dev eth2 parent 1:1 classid 1:12 htb rate 600kbit ceil = 1700kbit
tc class=20 add dev eth2 parent 1:1 classid 1:13 htb rate 200kbit ceil = 1700kbit
tc class=20 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=20 10
tc qdisc add dev eth2 parent 1:11 handle 20: sfq perturb 10
tc = qdisc=20 add dev eth2 parent 1:12 handle 30: sfq perturb 10
tc qdisc add dev = eth2=20 parent 1:13 handle 40: sfq perturb 10
tc qdisc add dev eth2 parent = 1:14=20 handle 50: sfq perturb 10

tc filter add dev eth2 protocol ip parent 1:0 prio 1 = u32 =20 match ip dst 194.x.x.254 match ip sport 80 0xffff flowid = 1:10
tc=20 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=20 prio 1 u32 match ip dst 194.x.x.250 flowid 1:12
tc = filter add=20 dev eth2 protocol ip parent 1:0 prio 1 u32 match ip dst = 194.x.x.200 =20 flowid 1:13

At the begining every thing works fine ..But when = overlimits=20 begins to occur the class having overlimits hangs the traffic related to = that=20 class

I have got error messages in syslog as = follows

May 20 09:40:07 gesrouter kernel: HTB: bad diff in = charge,=20 diff=3D3938700 now=3D1894047744 then=3D4294959104 j=3D46368551

these messages continue for ever..

What can the problem be ?
