You could have posted a better question instead of simply asking the
list how to do everything. If you don't know how to do simple bandwidth
management stuff I would suggest not trying. If you are so new to
Traffic control and Linux, get some professional consulting.

ANyway read up on the following and then get back to the list after
forming a proper question:

  Linux Advanced Routing HOWTO
  Traffic Control HOWTO
  Traffic Control howto will tell you a lot about what you want.
  LARTC list archives
  Google.

I would suggest using HTB for this.

Cheers!

[LARTC] HTB classes and SFQ qdiscs showing 0 sent bytes

[Animesh Bansriyar]

Hi All,

I have set up a test script to limit incoming connections to my Network
Server like this. Running SuSE Linux Professional 8.2. The snippet from
my script is:



#Deleting previous root handle

tc qdisc del dev eth0 root

# Adding new root handle
tc qdisc add dev eth0 root handle 1 htb default 30

#Dividing the classes

tc class add dev eth0 parent 1: classid 1:1 htb rate 4Mbit ceil 4Mbit

tc class add dev eth0 parent 1:1 classid 1:2 htb rate 1Mbit ceil 1Mbit
burst 15k
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 1Mbit ceil 1Mbit
burst 15k
tc class add dev eth0 parent 1:1 classid 1:4 htb rate 1Mbit ceil 1Mbit
burst 15k
tc class add dev eth0 parent 1:1 classid 1:5 htb rate 1Mbit ceil 1Mbit
burst 15k

#Addming SFQ beneath these classes

tc qdisc add dev eth0 parent 1:2 handle 2 sfq perturb 10
tc qdisc add dev eth0 parent 1:3 handle 3 sfq perturb 10
tc qdisc add dev eth0 parent 1:4 handle 4 sfq perturb 10
tc qdisc add dev eth0 parent 1:5 handle 5 sfq perturb 10

# Adding some filters

tc filter add dev eth0 protocol ip parent 1:2 prio 1 u32 \
match ip src 192.168.1.1/24 classid 1:2
tc filter add dev eth0 protocol ip parent 1:3 prio 1 u32 \
match ip src 192.168.1.2/24 classid 1:3
tc filter add dev eth0 protocol ip parent 1:4 prio 1 u32 \
match ip src 192.168.1.3/24 classid 1:4
tc filter add dev eth0 protocol ip parent 1:5 prio 1 u32 \
match ip src 192.168.1.4/24 classid 1:5

Notice the "Sent 0 bytes" for both teh SFQ qdiscs and the HTB classes. I
am stuck over here. Please suggest what might be wrong and whether my
approach is right.

Animesh
