first you cant use limit of 9 bits /s it is 1 byte /s, so completely
unreasonable speed. set it to 50 bytes/s at least
another popstential problem that you are using independent root classes for
each client
that means they wont share bandwitch. customer a will always get 256 kbits
and others will get their ceil limit all time.
and my suggestion is to NOT touch default or you may have problems
if rate = ceil then just specify rate.
if you want your clients share bandwitch then you need to create one root
class and attach everyone to it.
this will look like this:
tc qdisc add dev eth1 root handle 1: htb default 1
#Classes#
tc class add dev eth1 parent 1: classid 1:5 htb
rate 230kbps #root (set rate to 80-90% of link capacity)
tc class add dev eth1 parent 1:5 classid 1:100 htb
rate 9bps ceil 9bps #ICMP
tc class add dev eth1 parent 1:5 classid 1:100 htb
rate 144kbps ceil 230kbps #customer A
tc class add dev eth1 parent 1:5 classid 1:101 htb
rate 16kbps #customer B
tc class add dev eth1 parent 1:5 classid 1:111 htb
rate 32kbps #customer C
tc class add dev eth1 parent 1:5 classid 1:121 htb
rate 32kbps #customer D
b,c and d will get always and only rate amount of trafic
