Hullo :) I appear to be having a common problem, but the standard fix hasn't worked for me :/ I'm using a 2.4.23 kernel, with QoS options thusly: # QoS and/or fair queueing # CONFIG_NET_SCHED=y # CONFIG_NET_SCH_CBQ is not set CONFIG_NET_SCH_HTB=m # CONFIG_NET_SCH_CSZ is not set 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_QOS=y CONFIG_NET_ESTIMATOR=y CONFIG_NET_CLS=y CONFIG_NET_CLS_TCINDEX=m CONFIG_NET_CLS_ROUTE4=m CONFIG_NET_CLS_ROUTE=y CONFIG_NET_CLS_FW=m CONFIG_NET_CLS_U32=m # CONFIG_NET_CLS_RSVP is not set # CONFIG_NET_CLS_RSVP6 is not set CONFIG_NET_CLS_POLICE=y The whole wshaper.htb script executes fine until the final two commands, and running the first one manually gives me: $ tc qdisc add dev eth0 handle ffff: ingress RTNETLINK answers: Invalid argument Now, the standard solution I've seen is "get a newer tc", and one report [1] said that Debian's unstable one worked fine... so I backported it to woody, but had exactly the same problem :/ I even saw the q_ingress.c and q_htb.c files being compiled OK during the 'debian/rules binary-arch' procedure so the code must be in the tc binary. If I mis-type 'ingress', then the error changes to "RTNETLINK answers: No such file or directory" so it must be seeing /something/ ... Any ideas? :D Cheers, Gavin.
