LARTC - Apr 2007 - PPPoE and shaping

Hi all,
I have a little problem with my home-made slackware linux server.

Here is the scenario:
1. I have a local wifi network
2. my server do masquerading and exit in internet via a PPPoE connection

Goals:
1. not use SQUID
2. shaping the traffic with classes
3. emule connection must have minimum priority and a band-limit of
10KBytes/s in uplink (server--->internet)

Any idea?
Thx,
Diego

Hi Diego,
for shaping, you can use the HTB queuing discipline in the linux traffic
control. 
For the configuration you can use tc or tcng. More Informations you can find
hier: http://www.linux-ip.net/ 
And hier you can find a lot of configuration samples:
http://www.linux-ip.net/code/tcng/
And also in the project folder of tcng you can finde a lot of examples.


For example: i´ve used the standard ports of emule

#include "fields.tc"
#include "ports.tc"
#define UPLOAD 600kbps

dev ppp0 { /* 1Mbit */
    egress {
        class ( <$emule> )  if tcp_dport == 4661 || udp_dport == 4665 ||
udp_dport == 4672;
        class(<$other>) if  1;
        htb () {
            class ( rate UPLOAD, ceil UPLOAD) {
                $ssh   = class ( rate 10kBps, ceil UPLOAD  );
                $bulk  = class ( rate 520kbps, ceil UPLOAD) {sfq(perturb
10s);}
                }
        }
    }
}
----------------------------------------------------------------------------

The tc code looks like this:
----------------------------------------------------------------------------
-----------
tc qdisc add dev ppp0 handle 1:0 root dsmark indices 4 default_index 0
tc qdisc add dev ppp0 handle 2:0 parent 1:0 htb
tc class add dev ppp0 parent 2:0 classid 2:1 htb rate 75000bps ceil 75000bps
tc class add dev ppp0 parent 2:1 classid 2:2 htb rate 10000bps ceil 75000bps
tc class add dev ppp0 parent 2:1 classid 2:3 htb rate 65000bps ceil 75000bps
tc qdisc add dev ppp0 handle 3:0 parent 2:3 sfq perturb 10
tc filter add dev ppp0 parent 2:0 protocol all prio 1 tcindex mask 0x3 shift

Hi diego,
The traffic control should be done on your router. Only the router know the
both networks, internet and LAN. That s why, I don´t think, you will have
problems with the masquereading. But how do you use emule?? Do you use
nating? Have you any nating Rules for emule in your iptables? (otherwise,
emule will have a low ID)

>And, can I create shaping classes based on source IP of the local
>network? I tried, but also here masquerading operation loses
>information about original local IP...
Yes, you can do this. You can create for example  a class like this:

class if ip_dst == 192.168.0.3;  


Simo

You say PPoE: I assume you are talking about an ADSL not SDSL 
connection. If so, the "ADSL-optimizer" package by Jesper is the 
technologically most advanced solution: http://www.adsl-optimizer.dk/ 
(at least it was when I last checked)

I have been running it for months now without the slightest hitch. (With 
the patches from Russell Stuart.) It solved all my connection problems.

Best regards,
Arik
