[LARTC] Bandwidth by port

[David Coello]

Hi

I am trying to limit the bandwidth by port buy without success.

The code is :

# Disciplina de encolamiento
tc qdisc add dev eth1 root handle 10: cbq bandwidth 10Mbit avpkt 1000 mpu 64

# Clase
tc class add dev eth1 parent 10:0 classid 10:1 cbq bandwidth 1kbps rate 
1kbps allot 1514 prio 1 maxburst 10 avpkt 100 bounded isolated

# Filtro
# tc filter add dev eth1 parent 10:0 protocol ip handle 3 fw classid 10:1

tc filter add dev eth1 parent 10:0 protocol ip u32 match ip dst 
0.0.0.0  match ip sport 20 0xffff flowid 10:1
tc filter add dev eth1 parent 10:0 protocol ip u32 match ip dst 
0.0.0.0  match ip sport 21 0xffff flowid 10:1

What am i making bad? I have probed with mark&iptables but with identical 
result. When i make ftp i download without band limit.

Thanks and regards
                                         David Coello

Ftp is very difficult to shape because it can use dynamic ports.  Try using 
active or passive ftp.  I'm not sure wich one uses fixed ports.

But why the code of above doesn´t work? Anybody knows other systanx thats 
works to limit bandwidth by port?

Thanks and regards

RE: [LARTC] Bandwidth by port

[Serge Maandag]

Hmm,

I'm brand new to both tc and the list, so forgive me if I'm uttering nonsense :)

The example below seems good to me if eth1 is the interface connected to the side your clients are on, not the side the ftp servers are on. Are u sure that is the interface setup you have? I have done a similar setup, but based on ip-range. I both used fw marks and route realm marks and that worked in both occasions.
