Hi All,
I want to setup a machine to connect to internet at a limited rate of 64 kbps.
That machine is connected to a switch. so my LAN and Internet both comes from the same eth0.
How can I limit only the internet access from this machine to 64kbps and still using 100mbps for LAN
I am trying to implement this Please guide me If i am wrong.
I mark all the packets going out to LAN.
Then I can setup a root qdisc to classify packets based on that mark. If match then I can setup a class to accept those setup a fifo for those packets. but if the packets are not for the LAN then i can pass them to other class which is tbf shaping at rate 64kbps.
Am i right on these lines. This is the setup
+------------+ eth0 +-----------+ internet | machine |---------------| Switch |------------- +------------+ +-----------+
trying to get some thing like this
root qdisc (CBQ or something) / \ / \ / \ / \ class class Internal LAN Pcakets Any other unclassified Packets | | | | FIFO TBF (rate 64kbps)
Please Help me out with marking the packets and to classify them. Just started off with Traffic Shaping. gigles...... : )
It is alos possible to alternatively to mark internet traffic as it would be less in comparison to LAN and thus processor friendly.

I would use netfilter + HTB something like -
$TC qdisc add dev eth0 root handle 1:0 htb default 0 $TC class add dev eth0 parent 1:0 classid 1:1 htb rate 64kbit
$TC filter add dev eth0 parent 1:0 protocol ip handle 1 fw flowid 1:1
$IPTABLES -t mangle -A POSTROUTING -o eth0 --dst ! 192.168.0.0/24 -j MARK --set-mark 1
Depending on what the PC does it may be nicer to priorotise empty acks / udp headed for the internet over bulk traffic.
Andy.
