Hello, I''m newbie to HTB and need to solve really simple problem: I have an single IP internet connection @ 1024kbit attached to a linux box (2.4.21), doing NAT for clients at internal 192.168.1.x network. I need to setup a simple traffic shaping, for a single PC 192.168.1.2 I wish to guarantee minimum rate of 768kbit, for others 32kbit. Maximum rates must be always full speed (1024kbit) ! Can you please tell me what''s wrong with that (wlan0 is the internal iface), because this does not work (192.168.1.2 does not get the guaranteed bandwidth, but only a 1/n of bandwidth for case that another n stations saturate the line). Thank you. My script follows. tc qdisc del dev wlan0 root #by default, all clients go through slow :30 class tc qdisc add dev wlan0 root handle 1: htb default 30 tc class add dev wlan0 parent 1: classid 1:1 htb rate 1024kbit ceil 1024kbit # i wish :10 class 768-1024, :30 class 32-1024 tc class add dev wlan0 parent 1:1 classid 1:10 htb rate 768kbit ceil 1024kbit prio 0 tc class add dev wlan0 parent 1:1 classid 1:30 htb rate 32kbit ceil 1024kbit prio 2 tc qdisc add dev wlan0 parent 1:10 handle 10: sfq perturb 10 tc qdisc add dev wlan0 parent 1:30 handle 30: sfq perturb 10 # client 192.168.1.2 is privileged, should be in :10 class tc filter add dev wlan0 protocol ip parent 1:0 prio 0 u32 match ip dst 192.168.1.2 flowid 1:10 _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

So take 1000kbit as the ceil and not 1024kbit.> # i wish :10 class 768-1024, :30 class 32-1024 > tc class add dev wlan0 parent 1:1 classid 1:10 htb rate 768kbit ceil > 1024kbit prio 0 > tc class add dev wlan0 parent 1:1 classid 1:30 htb rate 32kbit ceil > 1024kbit prio 2Give both classes the same prio.
