HTB Problem

Bart007 · 08-09-2006, 03:48 AM

this is my script :

Code:

tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 512kbit ceil 512kbit burst 5kbit


# Direct traffic to classes based on firewall MARK rules
tc filter add dev eth0 parent 1: protocol ip handle 10 fw classid 1:10

iptables -A OUTPUT -t mangle -d 192.168.1.0/24 -o eth0 -p tcp --sport http -j MARK --set-mark 10

Distrib : Fedora Core 5
The question : Why do i have an http rate of almost 150Ko/s instead of 64Ko/s !? (the rate is the same tested with another protocol in iptables)

I cant c anything 64kbits in ur scripts

Bart007 · 08-09-2006, 06:27 AM

sure, there isn't 64Kbit
But I was speeking about 64Ko/s = 512kbit/s

I tested the same script on 2 other servers (under Fedora Core 5 and Fedora Core 3) and it works fine !

I tried to reinitalise everything on the server where the problem appears by this commands

Code:

iptables -F
iptables -t mangle -F
tc qdisc del dev eth0 root 2> /dev/null > /dev/null

or

Code:

tc qdisc del dev eth0 root

and the problem stay the same.

see below the result of class show :

Code:

[root@FC5-Service-server ~]# tc -s -d class show dev eth0

It is probably a problem with my kernel (few time ago, during my tests, it had an exception ).

I'll reinstall it when the new version of Fedora will appears
