[LARTC] I thought it was right... please take a look...

Hi

I dont think my script is quite right but I just cant see why. If you could have a look at it and let me know if anything is wrong or suggest any better ways of making this happen.
I have a 256kbit link, I want to give half of that (approx 124kbit) to a web site we run and let it burst to the full link if the bandwidth is not used (classid 1:10).
The other half of the link is divided into 4 parts that each have 31kbit. I want these classes to be able to burst to half the link (124kbit) if the bandwidth is not used (classid 1:20 -> 1:50).

What is happening is that no traffic ever gets over 124kbit/sec even traffic that should be in 1:10. My script is below.

Thanks in advance

Jeremy


        # Root
        tc qdisc add dev eth0 root handle 1: htb default 50

        # Parent to allow sharing
        tc class add dev eth0 parent 1: classid 1:1 htb rate 248kbit burst 15k

        # Main classes
        tc class add dev eth0 parent 1:1 classid 1:10 htb rate 124kbit ceil 248kbit burst 15k
        tc class add dev eth0 parent 1:1 classid 1:20 htb rate 31kbit ceil 124kbit burst 15k
        tc class add dev eth0 parent 1:1 classid 1:30 htb rate 31kbit ceil 124kbit burst 15k

The scripts looks ok to me.
Are you sure the filters are working ?  You can check with 
tc -s -d class show dev eth0
and hopely the counters of bytes/packets are incrementing.

And what if you make 1:10 the default class and remove all the filters so 
packets must end in 1:10?
