I want to limit ftp bandwith to 128Kb. In a RH 7.2 box I have: eth0: 200.39.186.1 eth1: 192.168.1.1 I use these rules: tc qdisc add dev eth0 root handle 10: cbq bandwidth 10Mbit avpkt 1000 tc class add dev eth0 parent 10:0 classid 10:1282 cbq bandwidth 10Mbit rate 128Kbit allot 1514 weight 12Kbit prio 5 maxburst 20 avpkt 1000 bounded tc qdisc add dev eth0 parent 10:1282 sfq quantum 1514b perturb 15 tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip dport 21 0xffff flowid 10:1282 But users accesing ftp from 192.168.1.0/24 are allowed more that 128K, any idea aboout how to solve it? Or do you have any other solution for this? Thanks, Omar
