I am trying to run tc commands, specifically tc qdisc add dev ppp0 root netem delay 2000ms to add network latency so I can check that things at least won't break when network connection is poor
whenever I run that command I get: *RTNETLINK answers: Operation not supported* I have the following in my kernel defconfig (tried several combinations with parts of them, these options are taken from 3 sources who all say to enable different config options for tc for some reason): > > 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 =y > CONFIG_NET_CLS_TCINDEX =y > CONFIG_NET_CLS_ROUTE4 =y > CONFIG_NET_CLS_ROUTE =y > CONFIG_NET_CLS_FW =y > CONFIG_NET_CLS_U32 =y > CONFIG_NET_CLS_RSVP =y > CONFIG_NET_CLS_RSVP6 =y > CONFIG_NET_CLS_POLICE =y > CONFIG_NET_SCH_HFSC =y > CONFIG_NET_SCH_ATM =y > CONFIG_NET_SCH_MULTIQ =y > CONFIG_NET_SCH_NETEM =y > CONFIG_IP_ADVANCED_ROUTER =y > CONFIG_IP_MULTIPLE_TABLES =y > CONFIG_NETFILTER_NETLINK =y > CONFIG_NETFILTER_NETLINK_QUEUE =y > CONFIG_NETFILTER_NETLINK_LOG =y > CONFIG_NF_CT_NETLINK =y > CONFIG_NETFILTER_XT_TARGET_MARK =y > CONFIG_SCSI_NETLINK =y > > > > > thanks for any help
