limiting doesn''t work
Hi folks,
I read the fantastic LARTC How-to and after that i tried to limit one
host in my LAN for both down-and upload bandwidth usage.
I took section 15.9. and added uplink-limiting as I understood it from
the previous chapters.
Unfortunately it doesn''t work.
I ran the script and went to the specified PC, started a download, and
watched the rate. The rate was always about 2000 kbit/s,

QoS on a bridge+NAT
I have a setup where I have three NIC in a Debian box. I have eth1
conected to internet and eth0 NAT''ed to 192.168.1.1. eth1 and eth2 are
bridged together, given ip 192.168.122.2.
What I want to achieve is to perform traffic shaping on the bridge as
well as prioritizing the traffic from eth0 very low. (This is from
trental flat ...) However it seems that I am unable to perform thhe

I''m having some problems setting up qdiscs on a bridge.The config looks

how to borrow bandwith
Hi,All
I am using iproute2 to manage bandwith for ADSL router.High,medium,low priority are needed for different protocol port on the ADSL's upstream side,as following:
LAN --- |ADSL Router|------WAN
When there aren't traffic on the specific priority, its bandwidth should be borrowed by other priorities.But it doesn't work.Here is my script:

Problen in cbq , fw
Hi,
In my LAN Iam trying to make following setup:
- All the traffic generated by 10.0.2.1 should go to 10.0.2.11,
If
the destination of this traffic is internet than it should be
placed on its interface eth1. Outgoing traffic on eth1 should be
shaped.For this I am using fw filters and cbq.

Applying the same class to multiple interfaces
Hi All,
I''m trying to do some traffic shaping on an ethernet bridge. Currently,
I have the following setup working:
ifconfig eth0 down
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
brctl stp br0 off
ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
ifconfig br0 up
This creates a bridge consisting of eth0 and eth1. So far so good.

Bandwidth shaping script appears to incorrectly halve the bandwidth
Hi,
I''m trying to modify the Wondershaper script so achieve the following.
1. Prioritize traffic to the few IP addresses.
2. Everyone else should get a fair amount of bandwidth
The problem I am facing is when I run this script is that the bandwidth
seems to get halved. I tried to apply this script to a site where the
upstream and downstream were fully saturated. I immediately saw
