Question

1. ETH=$1
2. LATENCY=$2
3. LOSS=$3
4. JITTER=$4
5. BW=$5
6. sudo /sbin/tc qdisc del dev eth0 root
7. sudo /sbin/tc qdisc add dev eth0 root handle 1: netem delay $LATENCY         


        

Answer 1

Your handles and parent handles don't match. e.g change to:

7. sudo /sbin/tc qdisc add dev eth0 root handle 1:1 netem delay $LATENCY $JITTER 
8. sudo /sbin/tc qdisc add dev eth0 parent 1:1 handle 10:1 netem loss $LOSS
9. sudo /sbin/tc qdisc add dev eth0 parent 10:1 handle 20:1 htb default 1
10.sudo /sbin/tc class add dev eth0 parent 20:1 classid 0:1 htb rate $BW ceil $BW

and it should work.
