OpenNet Installation error need help new to OpenNet

[memran2]

I installed OpenNet on Ubuntu 14.04 using Oracle Virtual box on mac laptop by creating a Ubuntu virtual machine. Every thing worked smoothly at the end I got one error regarding the installation of NS-3. The error I have pasted below:

TASK [ns3 : Set NS3] *****************************************************************************
ok: [master]

TASK [ns3 : Download NS3] ************************************************************************
fatal: [master]: FAILED! => {"changed": false, "failed": true, "msg": "failed to create temporary content file: The read operation timed out"}

NO MORE HOSTS LEFT *******************************************************************************
to retry, use: --limit @/root/OpenNet/ansible/playbook.retry

PLAY RECAP ***************************************************************************************
master : ok=51 changed=36 unreachable=0 failed=1

It seems to me that ns-3 is not installed can anyone please guide me what should be the solution for this error.

Complete installation log file I can attach also if some one wants to look on installation log.

Emran

Hello Emran,
Download NS3 task does something similar to a wget command and places a tar file in your home directory. The command is executed from ansible/roles/ns3/tasks/main.yml and you can find more information about it here.

Common problems are:

• Lack of internet connexion
• Web page crashes (I have test it right now and it works)
• home_location variable of ansible/group_vars/all file is pointing to a wrong place where you do not have permission to write.

Do not forget to install and run OpenNet as root user!

Hello Daviddvs,
Many thanks for your help and support I have successfully installed the OpenNet.
Can you please suggest some good tutorial or video to learn OpenNet as from Internet I am not getting related material.
Sincere Regards,
Emran

Hi Emran,
Apart from the doc/TUTORIAL I can't recommend you any other material. I suggest that you to read the documentation about mininet and ns3 frameworks, as OpenNet is based on both of them. You may also take a look at the OpenNet examples (mininet/mininet/examples/opennet) about WIFI and LTE.
