i have a simple configuration: hostA(192.168.100.44) <-----> hostB(192.168.100.45).
I want to shape the traffic from hostB to hostA to a maximum of 10kbps: hostB# tc qdisc add dev eth0 root handle 1:0 htb default 11 hostB# tc class add dev eth0 parent 1:0 classid 1:1 htb \ rate 200kbps ceil 200kbps hostB# tc class add dev eth0 parent 1:1 classid 1:10 htb \ rate 10kbps ceil 10kbps hostB# tc class add dev eth0 parent 1:1 classid 1:11 htb \ rate 100kbps ceil 100kbps
bostB# tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \ match ip dst 192.168.100.44 flowid 1:10
With this setup, a wget run on hostA downloading from hostB has an average rate of 97.74 KB/s - it seems to be classified to the default classid 1:11, not classid 1:10. Also, the class statistics below show traffic accounted to class 1:11.

tc binary downloaded from http://luxik.cdi.cz/~devik/qos/htb/v3/htb3.6-020525.tgz.
hostB is a Slackware 9.1 running recompiled 2.4.22, cls_u32 and sch_htb loaded as modules.
If instead of matching ip dst for hostA i match ip src for hostB, it works as expected - rate is 10Kb/s with the following: hostb# tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \ match ip src 192.168.100.45 flowid 1:10 _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
