I'm using htb classes on my firewall to queue traffic and implement different restrictions on different protocols. tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 190 tc class add dev eth0 parent 1: classid 1:3 htb rate 2mbit burst 30k tc class add dev eth0 parent 1:1 classid 1:90 htb rate 50kbit ceil 384kbit burst 5k tc qdisc add dev eth0 parent 1:90 handle 190: sfq perturb 10 tc qdisc add dev eth0 parent 1:3 handle 310: sfq perturb 10 tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 3 fw flowid 1:3 This last line gets a "RTNETLINK answers: Invalid argument" I'm using kernel 2.4.18 with the htb and wrr patches on both the kernel and on tc in the kernel .config I have: CONFIG_IP_ADVANCED_ROUTER=y CONFIG_IP_MULTIPLE_TABLES=y CONFIG_IP_ROUTE_FWMARK=y I'm not really sure where else I could be going wrong, any advice would be greatly appreciated. _____________________________________________________________ David Watson, Network Manager, Team17 Software Ltd.

You attach class 1:90 to class 1:1, but you didn't create class 1:1 ?? Stef --=20 stef.coene@docum.org "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.openprojects.net
I missed a line in my report and I do in fact create a 1:1 class before attaching to it. I have found that if I change the prio value on the filter lines to unique numbers that I no longer get the error. I am however confused as to the meaning of the prio parameter, and I'm not sure why these filter lines need unique values or exactly what impact these values have.
