Hi, I have a problem with 'tc filter' on a 2.4.22 kernel from Slackware 9.1 distribution. The tc command binary is from htb3.6-020525.tgz (http://luxik.cdi.cz/~devik/qos/htb) I'm trying the following command sequence: tc qdisc add dev eth0 root handle 1: htb default 1 r2q 1 tc class add dev eth0 parent 1: classid 1:1 htb rate 1200kbit ceil 1200kbit tc class add dev eth0 parent 1:1 classid 1:1002 htb rate 20kbit ceil 1200kbit burst 1600 cburst 1600 tc qdisc add dev eth0 handle 1002 parent 1:1002 sfq perturb 10 tc filter add dev eth0 protocol ip parent 1:0 prio 10 u32 match ip src 10.0.0.2 flowid 1:1002 'tc filter' command returns: RTNETLINK answers: Invalid argument moreover, 'tc filter show' returns: RTNETLINK answers: Invalid argument Dump terminated Everything worked OK on another linux with older (2.4.20) kernel. Do you have an idea what's wrong?
