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

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
