Hello, I'm facing an issue that i have reported on Debian's BTS as a bug against iproute package. Prior to this i have been looking around trying to find out what could be wrong but had no success to get it to work. Below is a what i've reported on Debian's BTS as http://bugs.debian.org/215629 Here goes the story, thanks for any tip on the subject. Alex ---- I would like to add a fwmark filter to the original HTB based LARTC "WonderShaper" script (http://lartc.org/wondershaper/). I am using a self compiled kernel from latest sarge kernel-source-2.4.22 and based on kernel-image-2.4.22-k7 provided config file. The idea is to add a single additionnal fwmark filter : tc filter add dev ppp0 parent 1: protocol ip prio 10 \ handle 1 fw classid 1:30 When adding this line i get the following error message : RTNETLINK answers: Invalid argument If i modify the WonderShaper script, remove all "tc filter" lines but the fwmark filter one i get no such error. The filter seems to get declared just fine. >From here i can start uncommenting some of the "tc filter" lines provided in WonderShaper without getting any error. At some point when having enabled again 4 or 5 "tc filter" original lines the reported error strikes again. I have tried simplifying the script to something like this : tc qdisc add dev ppp0 root handle 1: htb default 60 tc class add dev ppp0 parent 1: classid 1:1 htb rate 450kbit tc class add dev ppp0 parent 1:1 classid 1:10 htb rate 450kbit tc class add dev ppp0 parent 1:1 classid 1:60 htb rate 450kbit tc qdisc add dev ppp0 parent 1:10 handle 10: sfq tc qdisc add dev ppp0 parent 1:60 handle 60: sfq tc filter add dev ppp0 parent 1: protocol ip prio 1 handle 1 fw classid 1:10 tc filter add dev ppp0 parent 1: protocol ip prio 1 handle 6 fw classid 1:60 Which works fine. Adding this single line triggers the error again : tc filter add dev ppp0 parent 1: protocol ip prio 1 u32 \ match ip tos 0x10 0xff flowid 1:10 ---> RTNETLINK answers: Invalid argument I am stucked here... i haven't been able to find anything related to this on the net and i hope not to be misusing 'tc'.
