Hi all,
I setup a Linux machine to act as Lan Authentication server. So, the
same script that redirect the http connection to a login web page, it
create some queues to limit traffic, login by login.
The PC uses only 1 ethernet interface that receive the packets source
routed to it and forward/nat to the external gateway using the same
interface.
For each login I create a queue like that:
tc class add dev '.$if_externa.' parent 1:1 classid 1:'.$filaDown.' htb
rate '.$banda_down.'kbit ceil '.$banda_down.'kbit prio 1'
tc filter add dev $if_externa protocol ip parent 1:0 prio 1 handle
::$filaDown u32 match ip dst $ipcliente/32 flowid 1:$filaDown
My problem is that most of the queues created does NOT get full rate as
defined. I can see the packets entering backlog with much less rate than
defined, ex:
class htb 1:b1 parent 1:1 prio 1 rate 256Kbit ceil 256Kbit burst 1926b
cburst 1926b
Sent 6644151 bytes 5435 pkts (dropped 0, overlimits 0)
rate 669bps backlog 107p
Htb rate average can be quite long and misleading.
I would tcpdump and see whether the rate looks OK with that.
If not see what the dequeue behaviour is - you don't show all your
rules, if you are using htb default class on root and shaping eth
remember arp will get delayed there unless you filter it elsewhere.
Andy.
