After upgrading from Fedora 16 to Fedora 17, Traffic Control no longer seems to work.
Running # tc qdisc show
will output:
qdisc pfifo_fast 0: dev eth0 root refcnt 2 bands 3 priopmap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
However, if I run # tc qdisc add dev eth0 root netem delay 100ms
or similar commands such as # tc ... loss 2%
or # tc ... corrupt 3%
I get the following:
RNETLINK answers: No such file or directory
Downgrading back to Fedora 16 allows me to use Traffic Control without this problem, so I'm convinced it's not a hardware issue.
This question is similar to tc netem possibly missing but I believe the right components were installed by checking # yum provides */tc
and ascertaining that tc is from the package iproute
, whose latest installation I have.
Is netem
part of another package I must also install?
