# 40.10 Paul 40.11 Mark

how do i show 40:1x is the ip w.x.y.z (and for the other ip's) ?




Working off the prensentation.. 
Basically we have a 256Kb connection (yes small fry)

## We Start at the root of the device, eth0
# Install HTB as the root qdisc, names it 1:0.
tc qdisc add dev eth0 root handle 1: htb
# This attaches a shaping HTB to the HTB root, 256kps with a 2k bucket
tc gdisc add dev eth0 parent 1: classid 1:1 htb rate 256Kbps burst 20k

#The first class is guaranteed 5Kbps of the 256Kbps, but can grow to 7
if available
#The second class however can take up to 240kbits (changed)
# 1.10 Paul 1.11 Mark
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 5Kbps ceil 7Kbps
burst 2k
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 5Kbps ceil 6Kbps
burst 3k
# 1:12 Mike 1:13 Brian
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 200Kbps ceil
220Kbs burst 4k
tc class add dev eth0 parent 1:1 classid 1:13 htb rate 200Kbps ceil
240Kbs burst 4k

## Filtering to Classify traffic
# When a packet enters the qdisc it needs to be classified. This is done
with 'tc filters':
U32="tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32"
$U32 match ip dport 25 0xffff flowid 1:10
$U32 match ip sport 80 0xffff flowid 1:11

## Shape incoming Traffic (IMQ)
modprobe imq numdevs=1
tc qdisc add dec imq0 root handle 40: htb default 22
tc class add dev imq0 parent 40:    classid 40:1  htb rate 256Kbps burst
20k
# 40.10 Paul 40.11 Mark
tc class add dev imq0 parent 40:1   classid 40:10 htb rate 5Kbps ceil
7Kbps burst 2k
tc class add dev imq0 parent 40:1   classid 40:11 htb rate 5Kbps ceil
6Kbps burst 3k
# 40:12 Mike 40:13 Brian
tc class add dev imq0 parent 40:1   classid 40:12 htb rate 200Kbps ceil
220Kbps burst 4k
tc class add dev imq0 parent 40:1   classid 40:13 htb rate 200Kbps ceil
240Kbps burst 4k

tc class add dev imq0 parent 40:10  classid 40:11 htb rate 240Kbps burst
4k

iptables -t mangle -A PREROUTING -i eth0 -j IMQ
# Push all Pauls traffic through IMQ
iptables -t mangle -A PREROUTING -i eth0 -p tcp -d 10.0.0.9 -j IMQ
--todev 0
ip link setup imq0 up

am i close? :)
