[Mini-NDN] mininet error

Thu Oct 13 08:57:30 PDT 2016

Can you attach the output for sudo ./util/install.sh -nv?

Don't know why it cannot find mn.

Are you running as root user? May be try non-root and use sudo.

when I write sudo mn I get the following error:
# mn
Traceback (most recent call last):
  File "/usr/local/bin/mn", line 4, in <module>
    __import__('pkg_resources').run_script('mininet===2.3.0d1', 'mn')

    raise ResolutionError("No script named %r" % script_name)

and when I write sudo minindn, I get the following:
# minindn

Does "sudo minindn" also fail?

You are using Mininet from github source, right?

mu ubuntu version is 16.04.1
and kernel version 4.4.23

I used steps stated in http://mininet.org/download/#option-3-installation-from-packages option 2

I used the command:
sudo ./util/install.sh -nv
and no error occured !

Junxiao is probably correct, can you give your operating system details?

Can you please detail the steps you followed to install Mininet?

Can you also go to the Mininet folder and try:
sudo ./util/install.sh -nv
and see if there are any errors?

Hi Sepehr

The kernel might be missing some modules. Use Vagrant ubuntu/trusty64 template, which is known to work properly.

Yours, Junxiao

Hello All,
I've tried to install mini-ndn by following steps in https://github.com/named-data/ mini-ndn/blob/master/INSTALL.m d<https://github.com/named-data/mini-ndn/blob/master/INSTALL.md>
and in one aspect, it requires installing mini_net,
again I follow the exact steps stated but when I try to use
sudo mn --test pingall
to see if it works well...
I encounter this error:
Exception: Error creating interface pair (h1-eth0,s1-eth1): RTNETLINK answers: Operation not supported
do you have any idea how can I handle it?
