Goodmorning I am trying to use traffic control on a slackware 9.1. I downloaded iproute2. The system comes with linux 2.4.22 so I run into problem with the compilation of the package. After diging in the list archives I found a post about using 2.4.21 for compile and it worked. This far ok. After that I issued: tc qdisc add dev $DEV handle ffff: ingress which worked ok with no error messages and after it I could see stats for it with tc -s qdisk. then I tried: tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match ip src\ 0.0.0.0/0 police rate 150kbit burst 10k drop flowid :1 and it brakes with RTNETLINK answers: Invalid argument Thank you very much in advance I am posting my .config |grep -i net CONFIG_NET=y # Networking options CONFIG_NETLINK_DEV=m CONFIG_NETFILTER=y # CONFIG_NETFILTER_DEBUG is not set CONFIG_INET=y CONFIG_NET_IPIP=m CONFIG_NET_IPGRE=m # CONFIG_INET_ECN is not set # IP: Netfilter Configuration # IPv6: Netfilter Configuration CONFIG_DECNET=m # CONFIG_DECNET_SIOCGIFCONF is not set # CONFIG_DECNET_ROUTER is not set # CONFIG_NET_DIVERT is not set # CONFIG_ECONET is not set # CONFIG_NET_FASTROUTE is not set # CONFIG_NET_HW_FLOWCONTROL is not set CONFIG_NET_SCHED=y CONFIG_NET_SCH_CBQ=y CONFIG_NET_SCH_HTB=y CONFIG_NET_SCH_CSZ=m CONFIG_NET_SCH_PRIO=m CONFIG_NET_SCH_RED=m CONFIG_NET_SCH_SFQ=m CONFIG_NET_SCH_TEQL=m CONFIG_NET_SCH_TBF=m CONFIG_NET_SCH_GRED=m CONFIG_NET_SCH_DSMARK=m CONFIG_NET_SCH_INGRESS=y CONFIG_NET_QOS=y CONFIG_NET_ESTIMATOR=y # CONFIG_NET_CLS is not set # Network testing # CONFIG_NET_PKTGEN is not set # Network device support CONFIG_NETDEVICES=y # ARCnet devices # CONFIG_ARCNET is not set # Ethernet (10 or 100Mbit) CONFIG_NET_ETHERNET=y CONFIG_NET_VENDOR_3COM=y CONFIG_NET_VENDOR_SMC=y CONFIG_NET_VENDOR_RACAL=y # CONFIG_NET_ISA is not set CONFIG_NET_PCI=y CONFIG_PCNET32=m CONFIG_NET_POCKET=y # Ethernet (1000 Mbit) # CONFIG_NET_RADIO is not set # CONFIG_NET_FC is not set # Network File Systems _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
