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@xxxxxxxx]# 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.
