I'm trying to setup some traffic shaping (using tc qdisc), but it's failing like this:

[root@haddock leif]# strace -e open tc qdisc add dev eno1 root netem delay 200ms
open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
open("/lib64/libelf.so.1", O_RDONLY|O_CLOEXEC) = 3
open("/lib64/libm.so.6", O_RDONLY|O_CLOEXEC) = 3
open("/lib64/libdl.so.2", O_RDONLY|O_CLOEXEC) = 3
open("/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3
open("/lib64/libz.so.1", O_RDONLY|O_CLOEXEC) = 3
open("/proc/net/psched", O_RDONLY)      = 3
open("//usr/lib64/tc//q_netem.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
RTNETLINK answers: No such file or directory


There is a man-page for tc-netem, which shows basically the same command as above in the synopsis.

qdisc seems properly setup (I think, not an expert on this area):

[root@haddock leif]# tc qdisc
qdisc noqueue 0: dev lo root refcnt 2
qdisc fq_codel 0: dev eno1 root refcnt 2 limit 10240p flows 1024 quantum 1514 target 5.0ms interval 100.0ms ecn


The package does not seem to provide a q_netem.so shared library:

[root@haddock leif]# rpm -q -l iproute | grep lib

/usr/lib64/tc/experimental.dist
