My ISP is doing it, so it can be done :)  They don''t block me, but the
speed
goes from 4mbit to 128kbit.

You can do it with iptables counters.  Read them each 15 minutes and count the 
bytes.  And trigger a script if it reaches it''s maximum.  I
don''t think it''s
hard to implement.  If you do this, make sure you can detect a counter reset.

The quota is 10GB up + down and max 2GB up for the last 30 days.  I''m
not a
big downloader so I almost never hit the maximum.

If kazaa is your problem, you should that traffic in a different class.  Maybe 
the layer 7 filter can help : http://l7-filter.sourceforge.net/.  You can use 
it match kazaa traffic and put it a seprate, low bandwidth class.

Hi.
Just wondering if it is possible for example :If I limit an IP Address to
512kb/s, if It is possible to
stop him from using the net after he reaches a certain limit of bandwidth ,
lets say 5 meg a day/week/ or month,year or whatever.
I was thinking about maybe using a Packet counter like the one used at
http://wipl-wrr.sourceforge.net/wipl.html or
 http://bwmon.sourceforge.net/an and a script which activates a rule with
IpTables that denys all traffic from/to that IP Address after
the limit of total of max byte downloaded has been reached.
I was trying to to find something regarded on the net about BW controller,
watcher...etc
But couldnt find anything, Does someone know if this has been done, and how?

                Thanks.

                        Osgaldo

So that means you re guaranteed 128Kbit, and burstable to 4Mbps until you
reaches the limit for your quota. Cool stef (:

btw, how about my question regarding QoS stef? i need to implement QoS for
my network. There are still kazaa users and getting worse lately.
I need to limit all tcp connection for my network only 40Kbit for single
TCP stream eventhough they have huge bandwidth (256Kbps).

Regards,
Rio Martin.
