[LARTC] How to priorize Traffic

[Juan Ignacio Borda]

Hi guys, I want to priorize traffic comming down from internet on my 
ppp0 int
I want port 80 and 21 (and others ) to have preference over P2P traffic, 
I don't want to bann P2P just give to it less prio than other more vital 
services... does anyone know how to do it or where to read on.

Thanks in advance

That seems to be the million dollar question and it really isn't as
simple as your question puts it.  If you spend time learning a few
things, it will become much easier.  I would recommend the lartc howto
and the htb user guide.  The htb user guide made a lot of things more
clear to me.  I hope to have time to make a framework for easily
defining shaping rules soon.

If you want to do shaping for specific services there are over 11 different 
linux queuing methods to pick from, most here advise using HTB.

A ready made script to use HTB on your server exists, its called HTB.init. I 
suggest you have a look at this, it could get you up and running very quickly 
with your requirements.
http://sourceforge.net/projects/htbinit/

An alternative for shaping your network to improve performance.

A good way would probably be to look up some example scripts on the net 
that already deal with P2P. There are some that use IPP2P and / or 
l7-filter (two project that try to detect type of traffic by looking at 
the data of the packets).

My own script uses a combination of HTB / PRIO / SFQ qdiscs and puts said 
P2P traffic into the lowest PRIO band. I found this to be quite effective 
in my home network, although others might find it a tad too aggressive, 
because PRIO won't give any bandwidth to P2P as long as there are 
ssh/www/other packets to be sent / received.

You can have a look at the script here: http://www.metamorpher.de/fairnat/

If you're not shaping for clients behind a router, you'll need a bit of a 
different approach, but if you've already read the LARTC howto and other 
docs it might give you an idea of how to solve it in your own situation.
