Can someone suggest me some resources where I learn how to have control
over download and bandwidth over a small network.
My network setup is very simple star topology.

Why can''t the server keep track of how many each packets is being sent
to a particular ip address, if over the download limit drop all packets
from & to that ip. Of course the ip have to be static or the user have
to login before using the internet.
Is this concept right? If yes, what resources can help me to implement
it.

Trying to "control" the incoming traffic at Server (to use your
topology) is
very difficult. It can be done with IMQ, but setting that up requires
patching, and its not completely reliable.
The easiest way to "control" incoming traffic is to shape the traffic
flowing *out* of Server to router. This, in essence, means that the
traffic
coming *in* to router will be effectively controlled.
Of course, this is said with the caveat that of course you can''t ever
really
control download traffic. If someone decides to start pumelling you
with a
ton of UDP traffic, requested or otherwise, you can drop the packets
when
they get to you but they''ve already consumed your bandwidth so it
really
doesn''t matter. But its at least worth *trying* to control the
incoming
data since TCP, for its part, will (if behaving properly) slow down if
you
drop packets.

Jake, I think that if you just want very basic policing without any priorities, you can add an ingress qdisc like this: #tc qdisc add dev eth0 handle ffff: ingress and filter on destination IP sort of like this: #tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match ip dst 1.2.3.4 police rate 100kbit burst 10k drop flowid :1 #tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match ip dst 1.2.3.5 police rate 100kbit burst 10k drop flowid :1 etc... Hope this is right.. I''m kinda busy trying to debug why after installing Fedora Core 3 postfix is keeping everything deferred when I send through procmail for spamassassin...

Hey Jake Find it a bit hard to specificly understand what it is you want, but you might want to have a look on this: http://omg.wp.gg/wshaper-howto/ The example shown could be applied on more clients if neccessary or even specific ip segments of a network. - Rune Johannesen - Denmark> >Why can''t the server keep track of how many each packets is being sent to a particular ip address, if over the download limit drop all packets from & to that ip.
