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.
I don't know if this is *all* your problems, but there is a very obvious 
one here - all four of your ip matches are going to match exactly the SAME 
thing. (And therefore only one is ever going to match)

Why did you put the /24 on the end of the ip address ? That means that 
you're providing it a netmask, so 192.168.1.1/24 is refering to the entire 
class C subnet 192.168.1.x.

192.168.1.2/24 also refers to the same class C subnet. If the subnet is a 
/24 the last octet of the ip address is ignored. If you're really trying to 
match only on single ip addresses, take off the /24

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

2004-02-24 Thread 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

tc class add dev eth0 parent 1:1 classid 1:3 htb rate 1Mbit ceil 1Mbit

#Addming SFQ beneath these classes

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
