VirtualBox in GNS3 under Linux part2

Continuing the previous post  VirtualBox in GNS3 under Linux part1, I will show below the steps on how to make GNS3 work with Virtualbox using emulated VirtualBox host-only adapters. 

STEP 1 : Install VirtualBox and VMs
Install VirtualBox (current version is 4.3.6) and your favorite Virtual Machines.

VirtualBox in GNS3 under Linux part1

Following my previous post on Installing GNS3 v0.8.6 on Linux , now will make GNS3 work together with VirtualBox.

By the time GNS3 started supporting VirtualBox virtualization ( v0.8.1 ), things were made easier in using VMs in GNS3. You just tell to GNS3 which VMs to load. see below the steps in detail. For more info see GNS3 website.

Later ( easy installation ) it became even simpler and no need any more to start GNS3/VirtualBox in root access mode.

STEP 1 : Install VirtualBox and VMs
Install VirtualBox (current version is 4.3.6) and your favorite Virtual Machines.

802.1Q VLAN trunk in Linux

I need to configure an Ethernet interface as an IEEE 802.1q VLAN trunk on Linux Mint for Lab purposes so I can connect GNS3 with a physical Cisco Switch. So I will create 6 vlan interface using VLAN ID 101-106 on eth0 interface.

Install VLAN package

 sudo apt-get install vlan 

Installing GNS3 v0.8.6 on Linux

Below are the basic steps for installing GNS3 v0.8.6 on Linux Mint 15 ( should also work for other similar flavors) using the excellent work by  claydon_dan as posted in GNS3 Forum.

This version makes things much easier in installing GNS3 and Dynamips using PPA (Personal Package Archive). Reposting the steps below.

Step 1: Add PPA to your system

sudo add-apt-repository ppa:gns3/ppa

Installing GNS3 0.8.3 on Linux Mint 13 Maya

Below are the basic steps for installing GNS3 0.8.3 on Linux Mint 13 Maya (and Linux Mint 14)
Following same steps should work on Ubuntu Linux as well.

Installing GNS3 v0.8.2 on Ubuntu 12.04

Below are the basic steps for installing GNS3 0.8.2 on Ubuntu 12.04 and get it started. Video tutorials on  gns3 website .

Add Loopbacks in Ubuntu for GNS3

Running GNS3 on Linux and trying to reach the outside world, you will not be able to use your host PC to telnet to the virtual routers unless you create loopbacks. see related post in GNS3 forum
Below I post the steps for creating loopback on Ubuntu. After that you will be able to use your PC to telnet or ping to the virtual routers. (more details here)

Add hosts in GNS3 using VPCS on Ubuntu

The Virtual PC Simulator (VPCS) is a program that runs within Windows or Linux. It has limited functionality, but it allows pings and traceroutes. if you want to save memory and CPU cycles , VPCS is the application to go.
The VPCS can simulate up to 9 PCs.

When VPCS starts, it listens the ports from 20000 to 20008 and waits the
dynamips to connect, and sends the packets to the ports from 30000 to 30008.

More info in the GNS3 website here. From the official website go here.

Installing GNS3 0.7.4 on Ubuntu 10.10 maverick

GNS3 is  an excellent tool  for graphical network simulator that allows simulation from simple to complex networks.A complementary tool for network engineers and people wanting to study for certifications such as Cisco as well as Juniper.

It can also emulate many Cisco IOS router platforms , PIX/ASA Firewalls and Juniper JunOS

The program is an open source, free program and  may be used on multiple operating systems, including Windows, Linux, and MacOS X.

 Check GNS3 documentation website for more details.
