I recently upgraded my lab machine from Ubuntu 8.10 to 9.04. After the upgrade, I noticed GNS3 was not able to open saved projects. I tried several different things before I finally uninstalled GNS3 using the Synaptic Package Manager and installed it manually from the GNS3 website. Below is a video to walk you through the steps.

In this tutorial, you will add a virtual machine for Ethernet connectivity to branch1 and branch2 of your virtual voice lab. Although I use a separate vm in this tutorial, you can also simply add two more interfaces to the headquarters virtual PC if you are running short on PC resources.
I apologize for the delay in posting the next tutorial in the virtual voice lab but I ran into a problem communicating from the HQ router to the host Ubuntu server. I thought I was able to communicate from the HQ router to the host during the Headquarters build tutorial….but I was wrong.
While poking around the new GNS3.net forum, I found two very interesting howto posts. Jeremy Grossman (gns3 author) describes the processes needed to bridge a wireless NIC to GNS3 using both Linux and Windows.
Here are the links:

In the Virtual Voice lab series, I am using an Ubuntu Linux environment. To eliminate permissions issues, it is best that you run GNS3 as root.
Here are a couple issues I have experienced when running GNS3 as a normal user.
Not able to start dynamips.
Error msg: Can’t Connect to the hypervisor on port 7200
Not able to connect to a cloud object.
Error Msg: 206-unable to create Linux raw ethernet NIO
Error Msg: 206-unable to create Linux generic ethernet NIO
Error Msg: 206-unable to create UDP NIO
Most of us have used voice translations rules for digit manipulation to modify both ANI and DNIS. Did you know that you can also block calls based on ANI?
This tutorial will demonstrate how to install GNS3 Router Emulation Software on a Linux platform. I used Ubuntu 7.10 because I use it as my home OS and the most user friendly.
We all know dynamips is a great tool for creating virtual networks and testing router configurations. However, I can never seem to really understand a concept unless I use it in a "real" scenario. I will show you how I have started using dynamips as my personal internet router.
This tutorial will walk you through creating a cdrom image file with the genisoimage command in Ubuntu linux.
This tutorial is an update to a previous tutorial NoMachine install on Ubuntu 6.10. The NoMachine install on Ubuntu 7.04 is significantly easier than 6.10.
