Thread: [Devil-Linux-discuss] Bandwidth management with DL

Hi all,

I need to find a way to prioritize traffic (based on source IP) on one
of my low-bandwidth sites. I remember looking into this a long time ago
and coming up without any clue...

Is there a way to do this with DL and, if so can anyone point me in the
right direction please?

Thanks a lot
Frank

Frank,

I attached the traffic shaping parts of my firewall script.
I don't remember where I got the code from, but it works great for me  
to control the outgoing traffic.

Thanks Heiko,

this seems to be rather powerful and yet understandable.

I have two constraints that make my problem different, I believe: 
*) I need to limit incoming traffic (the uplink is symmetrical, and
downloads, streaming, youtube, etc sometimes eat the incoming bandwidth)

*) I have several internal NICs: the 'bad' guys (ie students) are one
one NIC, and the 'nice' guys (School personnel) are behind another NIC.

So what I need to do is penalize eth1 over eth3 when [incoming-on-eth0 |
outgoing-on eth1 + eth3] exceeds a certain level...

I would probably need a qdisc that spreads several devices.... 
like IMQ (but this is not explained in great detail in LARTC)

Thanks for any clues,

Frank

It is possible to do QoS for outgoing traffic however not so much for
incoming as you cannot modify how fast a peer will send packets to you.

I don't know what is provided in Devil, I used to use wondershaper in
Debian. It is a set of scripts so should be easily adapted in Devil if
needed.

Frank,

I'm shaping traffic with Shorewall (built into DL). Using methods described on 
page www.shorewall.net is possible to shape not only outgoing traffic, but 
(partially) incoming traffic too.
