Package: iproute
Version: 20080108-1
Severity: normal
--- Please enter the report below this line. ---
I tried out these commands from [1] and they didn't work:
# tc qdisc change dev eth0 root netem corrupt 0.1%
RTNETLINK answers: No such file or directory
# tc qdisc change dev eth0 root netem delay 100ms
RTNETLINK answers: No such file or directory
I tried on stock debian kernel 2.6.24-1-686 SMP, and also on a custom
built 2.6.25-rc4, and I get errors on both.
I tried downloading the latest iproute2 sources, and I still got the
same. I downloaded the latest git sources of iproute2 with same results.
How can I find out what file is RTNETLINK missing? (see attachment for a
strace output)
I see it searches for q_netem.so and fails, but AFAICT this is now built
into tc directly, and it doesn't abort there, so I don't think that is
the problem.
