LARTC - Jan 2001 - Trying to do something like the "nice" command, but applied to network traffic

Hello, i''m quite new to using QoS. I''m trying do to something
like what the
nice command do, but instead of processes, i''d like to manage bandwidth
(of
course) 

I saw examples in the Howto, describing what to do do divide bandwith, for 
instance in two parts :

Considering a total bandwidth of 10Mb/s :

2mb is reserved to one interface
8mb is reserved to second interface.

Both are marked "bounded"

Later in the howto, is explained how to let the first interface (which is 
limited to 2mb/s) to use some of the second interface''s bandwidth
(which is
limited to 8mb/s).. It looks good.. But what I didn''t understand is :

If the interface which is limited to 2Mb/s uses bandwidth of the other 
interface, where is the 2Mb/s limitation ??

Is the bandwidth "borrowed" only if the 8Mb/s limited interface does
not use
the total of 8 Mb/s ? If it''s the case, it''s just what I
intend to do. If
not, can you explain me what does it do?

I hope I was not too long, and was clear enough!

Thanks for your help!

I have an ISDN connection here at my apartment and wanted to make sure
to have enuf bandwidth to play a game while one of my roommates is
surfing.
I compiled the 2.4 kernel for advanced routing and tos and iptables as
modules.

I have iptables v1.2 and when adding a rule and then doing iptables -L
the list is empty tho the rules are applied.

When I type:
tc qdisc add dev ippp0 root handle 1: cbq bandwidth 64kbit avpkt 1000
I get the error:
RTNETLINK answers: Invalid argument

I found two good howto-sites but neither of them helps:
http://www.ittc.ukans.edu/~rsarav/howto/howto.html
http://www.ds9a.nl/2.4Networking/HOWTO//cvs/2.4routing/output/2.4routing-9.html

I''d really appreciate some help.

Thanx in advance,
 André Weidemann.

Try to compile this direct into the kernel. Not as modules.

Microsoft gives you Windows
Linux gives you the whole house

Hi Stefan,
if I do compile it directly into the kernel it doesn''t work at all. I
get an error message like "''filter'' not found in
table". I can''t
remember correctly.

But thx anyway,
 André.

You have to turn on the option
       Prompt for development and/or incoplete code/drives    
after that, you can select various options in the  
       networking -> QoS and/or fair queueing 
options menue.

Greetings
