So I simply get this error when I enter this command in my master VM:
sudo tc qdisc add dev eth0 root netem delay 97ms
RTNETLINK answers: File exists
Any idea how that could be fixed?
I am running this command in Ubuntu:
uname -a
Linux anmol-vm1-new 3.13.0-46-generic #79-Ubuntu SMP Tue Mar 10 20:06:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
ubuntu@anmol-vm1-new:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
Here's the content of /etc/network/interfaces file:
auto lo
iface lo inet loopback
source /etc/network/interfaces.d/*.cfg
ls /etc/network/interfaces.d/
eth0.cfg
And here's what I have in /etc/network/interfaces.d/eth0.cfg
# The primary network interface
auto eth0
iface eth0 inet dhcp
Additionally I get these errors:
ubuntu@anmol-vm1-new:/home/hadoop/yarnpp/workloads/RESULTS$ tc qdisc change dev eth0 root netem delay 100ms
RTNETLINK answers: Operation not permitted
ubuntu@anmol-vm1-new:/home/hadoop/yarnpp/workloads/RESULTS$ sudo tc qdisc change dev eth0 root netem delay 100ms
RTNETLINK answers: Invalid argument
In reference you might also want to look at this StackOverflow question I had asked for limiting the bandwidth.
