---------------------------
Template for VE - Debian 4.0 (standard)

Hosts for testing:
VE101 (172.16.254.241)- shaper (consolidation and traffic shaping/control in one point - eth1)
VE120 - firewall (firewalling)
VE4001 (192.168.5.220) - STORE - samba fileserver

tatooine (172.16.254.245)- PC connected to vlan123 (shape net)
admin-pc (192.168.5.XX) - my PC connected to vlan10 (local net)

NETWORK: Speed: 1000/100Mb/s Duplex: Full

local net: 192.168.5.0/24 vlan10, vmbr0
shape net: 172.16.254.0/24 vlan123, vmbr2

Test without shaping:
Test VE101 -> VE120 14.2MB/s
Code: 
 scp root@172.16.254.241:/file.bin .
root@172.16.254.241's password: 
file.bin     100%  256MB  14.2MB/s   00:18
Test VE101 -> tatooine 11.2MB/s
--------------
Simple script for shaping:

Code: 
----------
#!/bin/bash
tc qdisc add dev eth1 root handle 1: htb default 30

tc class add dev eth1 parent 1: classid 1:1 htb rate 10mbit burst 15k

tc class add dev eth1 parent 1:1 classid 1:10 htb rate 5mbit burst 15k
tc class add dev eth1 parent 1:1 classid 1:20 htb rate 3mbit ceil 3mbit burst 15k
tc class add dev eth1 parent 1:1 classid 1:30 htb rate 1mbit ceil 1mbit burst 15k
tc qdisc add dev eth1 parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev eth1 parent 1:20 handle 20: sfq perturb 10
tc qdisc add dev eth1 parent 1:30 handle 30: sfq perturb 10

U32="tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32"
$U32 match ip dport 80 0xffff flowid 1:10
$U32 match ip sport 22 0xffff flowid 1:20
