Gns3 cloud | Connect your physical NIC  or network with GNS3

This article is about the connection of GNS3 with cloud interface though which you can connect your gns3 devices with real networks or internet.

Gns3 Cloud is use for connecting the gns3 device’s interface to your PC interface/physical interface.  In this way you can make connection between your gns3 device and your local network or with internet. You can browse the gns3 cloud in end devices tab in gns 1.3 or later version.

How to configure cloud in gns3:

You can connect the gns3 device with your physical interface easily.  You need to follow these steps:

  1. Drag the cloud from end device on the gns3 stage.
  2. Right click on cloud and click on the configure. Now select the physical interface from drop-down menu which you want to connect with GNS3 and click on add and then on OK.
  3. Now drag the other device on stage, in my case I have inserted a router which will be connected to physical NIC. Create the connections between you gns3 device and NIC.GNS3 cloud lab
  4. Now power-on the router and once it is load assign the IP address to router from same subnet as of your physical interface. My physical NIC have the IP address of address of NIC
  5. Therefore I have assigned the IP address to router interface f0/0. You can use the following commands for configuring interface of router.

ESW1#conf t

ESW1(config)#interface f0/0

ESW1(config-if)#ip address

ESW1(config-if)#no shut

ESW1#ping of gns3 cloud

  1. After assigning the IPs, you can test your connectivity by ping your IP address of modem/router. In my case it is
  2. If you want to connect your gns3 router to internet you need to add a default route or static route for internet. You can do it with the following commands.

ESW1(config)#ip route



Where is the IP address of my modem/router (connected with physical NIC and have internet connectivity). For testing you can ping your any live Ip address. Where I have test it with live DNS IP

How to create your own cloud with ownCloud 8 with NOIP on Unbuntu 14.04

Installation of owncloud on Ubuntu server 14.04 using NOIP:

This  guide will ride you for the step by step installation of own private cloud with ownCloud platform on an Ubuntu server. You can follow the guide for installation on Windows, Mac or Linux.

I’ve been a while using owncloud and point the user experience they offer me is charming, so today I will show a step by step guide on how to build your own cloud with ownCloud on a server Ubuntu 14.04.

For those who do not know it yet, ownCloud is a cloud with which you can synchronize files, calendar, contacts, notes and more through extensions such as bookmarks and sync data with your web browser. It’s free, open source and has application for Android, iOS and desktop client for Linux, Windows and Mac OS X.

Installation of NOIP on Ubuntu 14.04:

NOIP is a free dynamic DNS service which will replace your owncloud IP web address to your define domain name. You can download and install noip from its official website. Go to and sign up for new user, which is simple like the other sign ups. One important thing that you need to define here is web address of your dynamic web server. (Which you will use for accessing you owncloud.)

singup noip

Complete the sign up then next step is to install the NOIP update client, for this you can go through the following commands and run one by one in Ubuntu terminal:

sudo -s                  (it will ask for user/password)

cd /usr/local/src/


tar xf noip-duc-linux.tar.gz

cd noip-2.1.9-1/

make install

To Configure the Client (optional)

/usr/local/bin/noip2 -C (dash capital C, this will create the default config file)

Next step is to enable the port forwarding. Port forwarding forward the any request coming from out of network to specific system, in our case this will be our OWNCLOUD server so that we can access it from anywhere.  Sign into your DSL router and find the option “port-forward” and then add the IP address of your OWNCLOUD server as port forward. You can refer to your router guide in case of any trouble in configuring port-forwarding.

Installation OF owncloud 8 on Ubuntu 14.04:

 Download owncloud from then use the following commands for installation of owncloud 8 on Ubuntu 14.04. Open the terminal in Ubuntu & then paste the following commands one by one into terminal.

sudo sh -c “echo ‘deb /’ >> /etc/apt/sources.list.d/owncloud.list”



sudo apt-key add – < Release.key 

sudo apt-get update

sudo apt-get install owncloud

 This will start installing owncloud

During the installation it will ask for SQL root password, set the root user password.

Once the installation is complete, open the owncloud by using the URL in web browser with following formate:\owncloud

where is the dynamic DNS which we have created in NOIP installation, you can replace it with your address. When you access your owncloud first you may got the error message “Cannot write into apps directory” you can resolve the error message with by visiting link.

Once you fix it, fresh your page it will lead you to admin user page, create an administrator account, and complete all the following fields:

  • Owncloud user + password
  • user + password (database)
  • localhost

owncloud first login

Finally, we will click on to complete the installation. Login with user name & password that you have created in the previous step.

Upon entering we give links to install the applications for smartphone and the desktop client. With this we have managed to create our own cloud. It was a tough process, but I think it was worth it to be the real owners of our data.

I hope you have served this guide, I am very happy with ownCloud and am synchronizing files, calendar and contacts.

4 Best ways to create a Private Cloud|Technologies for Building Private Cloud

List of Open Source Private Cloud Solutions which ensure privacy of your files:

Private cloud data centers are used for improving efficiency and enhance the latest hardware and software flexibility with the primary task of automated computing. This article is related to private cloud solutions, we will review of private cloud computing service here.


OWNCloud is an option for those who have a space of hosting own server at an ISP. ownCloud is a solution that allows us to implement our own storage service in the cloud with which to store files, access them remotely (both desktop Windows, OS X and Linux from iOS and Android mobile devices) or share them with other users who give permission to our server.

Besides being able to mount our “own Dropbox” private cloud version, ownCloud can be an interesting platform to work together because we share calendars includes a task manager, a document viewer and can be integrated with LDAP and Microsoft Active Directory (for environments based on Windows domain controllers). You can read more about installation and configuration of owncloud from here.


OpenStack is a high profile project which aims to lay the foundations on which to deploy cloud infrastructures on open architectures. In other words, it allows us to deploy OpenStack service IaaS (infrastructure as a service) and what Microsoft Azure offers but, yes, in free software. This project is driven by industry heavyweights such as AMD, Cisco, Dell, HP, IBM, Yahoo !, VMware and Red Hat or originated from a joint project between RackSpace and NASA.

A commercial NAS

In addition to the infrastructure in the cloud, a NAS can serve as storage service private files with the ability to remotely access all our information. More and more commercial NAS that we provide this type of functionality either natively or via plug-ins made ​​by the community of developers.

NAS offer us this kind of options that include their products functionality and can remotely access or control our information even download torrents directly from the NAS. NAS storage offer that we can use as if they were our private cloud and access information through Internet comfortably, knowing that the storage is safe in our home.


FreeNAS is open source solution for cloud computing. FreeNAS is a Free BSD distribution that allows us to deploy our own NAS low cost using old PC we have at home and that, in this way, we can rescue from oblivion. Besides being an open source project, FreeNAS is especially interesting because it allows us to deploy our own infrastructure service online storage.

While installing FreeNAS is not complicated and its use in the network of our house is quite simple, we must acknowledge that make our files available in remote requires some time but worth a try and guarantee that we control our files. If you do not want to “emulate” a Dropbox we will always have the option to use the classic FTP server that is also included in this distribution.
