Hi,

I've tried every combination (except the RIGHT one, of course) to see what the tc cbq statistics are. I really just want to see what it's doing - I'm trying to rate limit napster/peer2peer apps, but they still seem to be hogging up all of my T1 bandwidth.

Here's my tc config rules, minus the long list of ports in the class:

tc qdisc del dev eth0 root  [eth0 is the Internet facing interface]
tc qdisc add dev eth0 root handle 1 cbq bandwidth 10Mbit avpkt 1000 cell 8
tc class change dev eth0 root cbq weight 1Mbit allot 1514

tc qdisc del dev eth1 root  [eth1 is the intranet facing interface]
tc qdisc add dev eth1 root handle 1 cbq bandwidth 10Mbit avpkt 1000 cell 8
tc class change dev eth1 root cbq weight 1Mbit allot 1514

tc class add dev eth1 parent 1: classid 1:50 cbq bandwidth 10Mbit rate 35Kbit weight 3Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded
tc qdisc add dev eth1 parent 1:50 handle 50 tbf rate 35Kbit buffer 10Kb/8 limit 15Kb mtu 1500
tc filter add dev eth1 parent 1:0 protocol ip prio 100 u32 match ip sport 1755 0xffff match ip dst 0/0 classid 1:50
tc filter add [etc....]


same filter adds for eth0

Thank you for assistance,
