Hi all

I've seen similar questions answered in these forums and as a result I've looked at stuff in www.lartc.org etc but still it doesn't seem to match what I am looking for.

I have a firewall/router running Fedora Core 6 and it connects to a 512kbs ADSL link. There's 4 or 5 PCs/laptops attached behind this firewall sharing the ADSL bandwidth. Unfortunately, one of the kids tends to eat up most of the bandwidth and I'm wondering how I can restrict the traffic to this one particular IP address? Let's say I'd like for instance to permit this address to get a maximum of say 50% of the available b/w?

Has anyone doen something like that?

Many thanks all

Us tc to control the user here is example to bound ip with tc class id to bound xxx.xxx.xxx.xxx ip to 128 kbit
Lan Eth0

## First Create the cbq id let sey your lan is 10 MB
tc qdisc add dev eth0 root handle 10: cbq bandwidth 10Mbit avpkt 1000

## Then Bound with parent with define different classid:1
tc class add dev eth0 parent 10:0 classid 10:1 cbq bandwidth 10Mbit rate 10Mbit allot 1514 weight 1Mbit prio 8 maxburst 20 avpkt 1000

## Now the set parent id with your classid and your speed rate
tc class add dev eth0 parent 10:1 classid 10:2 cbq bandwidth 10Mbit rate 128kbit allot 1514 weight 1Kbit prio 5 maxburst 20 avpkt 1000 bounded

## The Final Step bond classid with ip address
tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip dst xxx.xxx.0.2 flowid 10:2

## to Flush rules
tc qdisc del dev eth0 root

this is simple example to create single ip if you have to many ips to need to repeat this step with different classid


tc class add dev eth0 parent 10:1 classid 10:3 cbq bandwidth 10Mbit rate 64kbit allot 1514 weight 1Kbit prio 5 maxburst 20 avpkt 1000 bounded
tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip dst xxx.xxx.0.3 flowid 10:3


tc class add dev eth0 parent 10:1 classid 10:4 cbq bandwidth 10Mbit rate 256kbit allot 1514 weight 1Kbit prio 5 maxburst 20 avpkt 1000 bounded
tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip dst xxx.xxx.0.4 flowid 10:4


Happy linux !!

Hi could you please give us same in the htb.I heard htb is far more advanced.
Thanks for your help.

Abakali I very much apprciate your help, I'll give it a try!
