Linux – Wondershaper does not work

Since you're using Debian Linux, you can do it quite simple. You can use this script for "fair" repartition on the bandwidth:

#Put here your Internet-interface instead of eth1
ext_iface=eth1
eiface_addr=192.169.158.150

###############Remove shaper rules###############################3
iptables -t mangle --flush

tc qdisc del dev $ext_iface root 2> /dev/null > /dev/null

iptables -t mangle -D POSTROUTING -o $ext_iface -j shape-in 2> /dev/null > /dev/null
iptables -t mangle -F shape-in 2> /dev/null > /dev/null
iptables -t mangle -X shape-in 2> /dev/null > /dev/null

##############Adding shaper rules###################################
tc qdisc add dev $ext_iface root handle 1:0 htb default 10
tc class add dev $ext_iface parent 1:0 classid 1:1 htb rate 100mbit ceil 100mbit

tc class add dev $ext_iface parent 1:1 classid 1:5 htb rate 100mbit ceil 100mbit prio 0
tc class add dev $ext_iface parent 1:1 classid 1:10 htb rate 48mbit ceil 48mbit prio 0

tc qdisc add dev $ext_iface parent 1:5 handle 5: pfifo limit 5
tc qdisc add dev $ext_iface parent 1:10 handle 10: pfifo limit 10

iptables -t mangle -N shape-in
iptables -t mangle -I POSTROUTING -o $ext_iface -j shape-in

#Priority for pings
iptables -t mangle -A shape-in -p icmp -j MARK --set-mark 5

#Priority for Server Access
iptables -t mangle -A shape-in -s $eiface_addr -j MARK --set-mark 5

#Othet packets (user\'s internet traffic)
iptables -t mangle -A shape-in -m mark --mark 0 -j MARK --set-mark 10

tc filter add dev $ext_iface parent 1:0 prio 0 protocol ip handle 5 fw flowid 1:5
tc filter add dev $ext_iface parent 1:0 prio 1 protocol ip handle 10 fw flowid 1:10

Note that the users will get 48/n channel and there is two Mbs left for a reserve.

I use XEN 4.2.2 at the time of this reply.

• Remove rate=X from your guest config file and shut it down.
• Make sure your kernel have at least the following enabled:
• IP: advanced router
• TCP: advanced congestion control (all options enabled)
• QoS and/or fair queueing (all options enabled expect the debug ones)
• Install 'tc' command
• Verify it's working by running: tc -s qdisc ls dev eth0

If you get no errors, you're ready to modify /etc/xen/scripts/vif-bridge

Find this word 'online)'

Just add before ;;

tc qdisc add dev "$dev" root tbf rate 120mbit burst 20mbit latency 5ms peakrate 125mbit minburst 20mbit mpu 64

So the modified version of vif-bridge should look like this:

online)        
        setup_virtual_bridge_port "$dev"

        mtu="`ip link show $bridge | awk '/mtu/ { print $5 }'`"

        if [ -n "$mtu" ] && [ "$mtu" -gt 0 ]

        then

                ip link set $dev mtu $mtu || :

        fi         

        add_to_bridge "$bridge" "$dev"

        tc qdisc add dev "$dev" root tbf rate 120mbit burst 20mbit latency 5ms peakrate 125mbit minburst 20mbit mpu 64

        ;;

Find this word 'offline)'

Append to first line: do_without_error tc qdisc del dev "$dev" root

offline)
        do_without_error tc qdisc del dev "$dev" root

        do_without_error brctl delif "$bridge" "$dev"

        do_without_error ifconfig "$dev" down

        ;;

Using the above TBF rule your guest should have roughly 12.5MB/s upload and 14.0M/s download speed; a bit over 120Mbps

If you upload/download same time, both upload and download speed should be about 7.5MB/s ~ 150Mbps total bandwidth

This is what I got after an hour tweaking. If you find better values; please let us know
