Very embarrassing traffic shaping problem.

Hi all,

Due to my unsuccessful attempts,

could someone brief me on the Linux Traffic Shaper,
Either CBQ- or HTB-based. (Not the 'shaper' or 'MID-something' device.)

And help me solve this problem :

On my LAN ( 192.168.2.0/24 ), I'd like configure my Linux Box in order
to throttle the traffic that goes from the Internet down do my Linux
box; that is, through my gateway ( 192.168.2.1 ). Your help will be very
appreciated.

Only volatile test configuration matters; no init script.

Thanks.
A.B.

AFAIK, you can only shape outgoing traffic. This means you have to do
the shaping on your gateway. If eth0 is your Internet and eth1 your
lan connections, you shape traffic from your workstation to the
Internet on eth0 and traffic from Internet to your workstation on eth1.

Thanks for your answer, but I had good reasons to do so.


What I want is :

1) To have my work station not to consume to much from the Internet
bandwidth so that other stations on my LAN could share together a
guaranteed bandwidth of say 50kbit/s.

2) The way I would like to implement it, since my gateway is quite
stubborn, is by making my workstation to drop incoming TCP packets above
some rate, let's say 150kbit/s, regardless of the connexion they belong
to. (An overall inbound TCP traffic rate limit of 150kbit/s.)

3) This way, my TCP download streams (obviously not UDP things) would
auto-regulate themselves in order not to exceed this barrier, thus
controlling the overall (TCP) consumption of my workstation; which
should represent most of my Internet use, though.

4) I would agree if, for some reason, I had to set up a buffer (queue)
for this incoming traffic.

5) As a reminder, I only want to regulate the inbound TCP traffic
between the Internet and my workstation, not with other stations on my LAN.

6) I must concede that I would have better not to filter on IP traffic
in general, but on TCP traffic only.


In hope I was clear enough,

I thank you for more suggestions.

Bye,
