hello john

When i changed my iptable script from PREROUTING to OUTPUT it worked fine.
I have another query 
 can i mark the outgoing packets by using the mac address (in the below case i have used the ip address)

Advance Thanks
Vanitha

  According to the results ,
  packets are not filtered into  classid 1:2
  what is your testing scenario ?

  (notice , PREROUTING don't tack care of local generating packets )

      please use
      tc -s qdisc show dev eth1
      tc -s class show dev eth1
      tc -s filter show dev eth1

      to see where the packet goes ,
      or how much it borrows .....
      It seems your script can't regular the classid 1:2



      cheers

        Hi All,

        I was using CBQ to control the bandwidth rate , while i use the qdisc cbq with u32 filter and route filter it is 
        working fine ,but when i use fw classifier it seems that the bandwidth rate 100kbit is not picked.

        i have used the following commands 

        /sbin/iptables -I PREROUTING -t mangle -p tcp -d 172.16.1.81 -j MARK --set-mark 1

        /sbin/tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit cell 8 avpkt 1000 mpu 64
        /sbin/tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 10Mbit rate 10Mbit allot 1514 cell 8 weight 1Mbit prio 8 maxburst 20 avpkt 1000
        /sbin/tc class add dev eth0 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 100Kbit allot 1514 cell 8 weight 10Kbit prio 3 maxburst 20 avpkt 1000

        /sbin/tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 1 fw classid 1:2


        is that anything i have missed out ?
        i have tested these commands using Linux-2.4.10.

        Advance Thanks
        Vanitha
