A new tool called "Cisco image unpacker" has been added on the download page. This tool which is simple to use, can unpack Cisco ASA and IOS images to be used with GNS3, Pemu or Qemu. Please note that at the moment only ASA v7 and early images are supported in GNS3 and Pemu. Read the provided README file to know how to use it.

The next release of GNS3 is coming in a few weeks and we are pleased to open a new forum that is directly available on our website. This forum will help us to help you and improve the project.

We are proud to publish a new tutorial for GNS3 made by Mike Fuszner. This tutorial describe step-by-step and with lot of screenshots how to use GNS3, it is particularly recommended for beginners.

More advanced users will also find some very useful information:

• How to use virtual PC Simulator (VPCS) in GNS3.
• The configuration of a multi-tabs console under Windows (WinTabber) and Linux (Konsole for KDE4).
• Limit the CPU usage with BES (Windows) and CPULimit (Linux).
• Create a symbol library for GNS3.

Thanks Mike for this great contribution!

The GNS3 0.5 release is available. It includes bugs fixes and new features:

• Possibility to load .net files of other users (provided that there is a registered IOS image with the same model as the one used in the NET file).
• New detailed tooltips for nodes.
• A minimalist wizard raised when the configuration file is empty.
• A button to insert a picture on the scene.
• Decorative node support for creating network diagrams.
• Ghostios is now supported on remote hypervisors.
• A symbol manager with library support (a howto to create a symbol library will be released).
• Z values can be changed for annotations and inserted pictures.
• Automatic load-balancing on external hypervisors (choose multiple external hypervisors when recording an IOS image).
• New option to bind the hypervisor manager with an address/name other than 'localhost': useful for labs which use local and remote hypervisors.
• The DMG package includes two Dynamips binaries, one for Tiger and one for Leopard

Light simulated host support has been postponed to a future release. More information about future features can be found in the TODO .

We hope you will enjoy this release.

The GNS3 dev team.

I'm sure most of you have noticed that GNS3 is in a sort of pause at the moment, mostly because we have been very busy but also because there are only 2 "active" remaining members, I and Xavier, since my class mates graduated in February and started new jobs. Xavier concentrates on the administration of the GNS3 servers and services (Apache, mercurial etc.) and I to develop new features.

So we would like to say don't worry, the project is still alive! We are going to improve it soon and add new features. One of the things we would like to improve first is the support. With this goal in mind we created a wiki which need to be filled with labs, howtos etc. Everybody should also be able to correct the documentation. We hope this wiki will be useful for the community and that people will contribute. There are also some interesting videos that have been added on the documentation page

Enjoy and thank you to all our contributors!

After lot of efforts and problems to solve, GNS3 is now available in a DMG package for MacOS. This will avoid you to install and compile the dependencies (Python, Qt, PyQt and SIP) and save you some time.

Please note that languages are not included in this package. I will try to change this in a future release. Since this is the first time I made this kind of package, don't hesitate to report any other problems.

We hope you will appreciate this DMG package.
