If not, you are trying to load to module in the wrong kernel and that''s why you get the inresovled symboles problem.

Hello All, I''m new to QoS under Linux so please be indulgent with the following question. I try to run tc under Linux 2.4.20, my kernel has the following options: CONFIG_PACKET=y # CONFIG_PACKET_MMAP is not set CONFIG_NETLINK=y CONFIG_NETLINK_DEV=y CONFIG_NETFILTER=y # CONFIG_NETFILTER_DEBUG is not set # CONFIG_FILTER is not set CONFIG_UNIX=y CONFIG_INET=y CONFIG_IP_MULTICAST=y CONFIG_IP_ADVANCED_ROUTER=y # CONFIG_IP_PNP is not set CONFIG_NET_IPIP=m # CONFIG_NET_IPGRE is not set # CONFIG_IP_MROUTE is not set # CONFIG_INET_ECN is not set CONFIG_SYN_COOKIES=y [...] # QoS and/or fair queueing # CONFIG_NET_SCHED=y CONFIG_NET_SCH_CBQ=y CONFIG_NET_SCH_HTB=y CONFIG_NET_SCH_CSZ=y CONFIG_NET_SCH_PRIO=y CONFIG_NET_SCH_RED=y CONFIG_NET_SCH_SFQ=y CONFIG_NET_SCH_TEQL=y CONFIG_NET_SCH_TBF=y CONFIG_NET_SCH_GRED=y CONFIG_NET_SCH_DSMARK=y CONFIG_NET_SCH_INGRESS=y CONFIG_NET_QOS=y CONFIG_NET_ESTIMATOR=y # CONFIG_NET_CLS is not set but when I try to do: [root@mysystem]# tc qdisc add dev ppp0 root tbf rate 128kbit latency 50ms burst 1540 I get this: RTNETLINK answers: Invalid argument syslog says: modprobe: Can''t locate module sch_tbf if I compile it as a module, the module fails to load anyway (some unresolved symbols)... Do I miss an option that should be set in the kernel .config file ? Thanks for your help, Mathieu. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Not a tc problem.
