[LARTC] Simple shaping question

[LARTC] Simple shaping question

[Jonas Jasas]

I have linux box (does nat and firewall for small network) connected
to dsl. I want to set priorities for protocols (that nothing could
disturb web browsing). This is my rules (eth0 connected to internet):

/sbin/tc qdisc del dev eth0 root
/sbin/tc qdisc add dev eth0 root handle 1 htb default 30 r2q 100

/sbin/tc class add dev eth0 parent 1: classid 1:2 htb rate 900Kbit burst 15k

/sbin/tc class add dev eth0 parent 1:2 classid 1:10 htb rate 900Kbit
ceil 900Kbit
/sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match
ip sport 80 0xffff classid 1:10
/sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match
ip dport 80 0xffff classid 1:10

/sbin/tc class add dev eth0 parent 1:2 classid 1:20 htb rate 10Kbit ceil 900Kbit

I start to download from ftp it uses all bandwidth (as it should be),
when I start to download on web, web and ftp rated become more or less
equal :/ . I want that ftp traffic would be limited to 10kbit and all
other bandwidth would be left for web trafic.

What is wrong with my rules?
Thank you for advice!

Try chosing a lower limit for the 80th port at least 900-10, then add a 
sfq qdisc down the 1:10, 1:20 and 1:30 classes like this:

tc qdisc add dev eth0 parent 1:x0 handle 1: sfq perturb 10

It will work, i had that kind of problem before.

Regards.
