Hi Javier,

1) don't 'reply' to messages if you are starting a new question/topic/thread
2) a relevent subject would help too.

Hi, I have a litle problem with this code

I have two virtual ips (50 y 51) and this ips are the gateway

ip address add 192.168.0.50 dev eth1
ip address add 192.168.0.51 dev eth1
tc qdisc add dev eth1 root handle 1: cbq bandwidth 512kbit cell 8 avpkt \
1000  mpu 64
tc class add dev eth1 parent 1:0 classid 1:1 cbq bandwidth 512kbit rate \
100kBit avpkt 1000 prio 5 bounded isolated allot 1514 weight 1 maxburst 21
tc class add dev eth1 parent 1:0 classid 1:2 cbq bandwidth 512kbit rate \
100kbit avpkt 1000 prio 5 bounded isolated allot 1514 weight 1 maxburst 21
tc filter add dev eth1 parent 1:0 protocol ip prio 5 handle 1: u32 divisor 1
tc filter add dev eth1 parent 1:0 prio 5 u32 match ip src 192.168.0.50 \
flowid 1:1
tc filter add dev eth1 parent 1:0 prio 5 u32 match ip src 192.168.0.51 \
flowid 1:2

and this scrip say:

RTNETLINK answers: Invalid argument
RTNETLINK answers: Invalid argument
RTNETLINK answers: Invalid argument
3)
You should really run the commands in the script one by one, so you can
find out exactly which ones are failing.

I would suggest that the 'tc qdisc .... cbq' commands are failing - probabaly because
you don't have the cbq module in your kernel.

but, it could be the filter commands (u32 module), or something else.

regards,
