GNS3 Technical Blog

admin — Fri, 13 Nov 2009 05:01:37 +0000

Hi everyone!

I'm pleased to introduce the GNS3 technical blog where you will find interresting articles about the development of GNS3 and other related information. The first post is about how to emulate JunOS on your PC using Qemu, a topic I'm working on for the next release of GNS3. At the moment, the integration of JunOS with GNS3 is manual but the next version will provide an easier method.

Interesting article about GNS3

Today I've found this article about GNS3, nothing new but I think it gives a very good overview of our software. The next version of GNS3 is coming fast, so stay tuned ;)

GNS3 v0.6.1

admin — Wed, 13 May 2009 13:26:19 +0000

Hi everyone,

GNS3 v0.6.1 is released! this is a minor release that brings some improvements and bug fixes. Nothing really new but now we have a solid base to start making new features. Also the GNS3 binary version for Windows has been repackaged to include python 2.6 and Qt 4.5.1 dlls. A binary version (.app) for MacOS X should be released soon.

Improvements:

Copy an inserted image in the project's working directory and update its path in the .net file.
Prevent auto-generated interface notes to be recorded in the .net file.
Display an error msg box if a working directory can't be used by an hypervisor.
Check if a hostname has already been used when creating a new node.
Warn to use manual links when a user select a NM-16ESW module.
Check if GNS3 is running on a Windows 64 bits OS in order to choose the correct path to Putty.
Check IOS and working directories paths when creating new nodes and throw a warning to the user if something is wrong.
Button to edit project settings.

Fixes:

Prevent notes to be deleted when typing the delete key while editing.
Prevent NM-16ESW modules to be removed from routers when using Ethernet/FastEthernet links.
Tooltips update when starting/stopping/suspending routers.
Bug with Qt 4.5 on selected filter when openning a project (getOpenFileName)
99MB limit for pcmcia disks.
Unicode errors with TMP env variable on Windows.
AttributeError: value of `chassis' must be of type string.
Merge correct config paths when loading a .net create on a different platform.

Thanks for your support.

GNS3 on FreeBSD

admin — Tue, 17 Mar 2009 05:40:10 +0000

GNS3 is now available as a FreeBSD port.

FreeBSD users who have an up-to-date port database can install GNS3 with these following commands:

cd /usr/ports/emulators/gns3/
make install clean

Thanks to all the people who contributed to make GNS3 available on FreeBSD.

GNS3 0.6 released

admin — Sun, 14 Dec 2008 23:54:34 +0000

Hi everyone!

GNS3 0.6 is now released, it include some new features and improvements.

Users can change the workspace size.
Possibility to draw rectangles and ellipses.
Feature to automatically create labels of interface names.
Multi-links drawing (no overlaps).
Snapshot feature.
Interface names are included in the Generic Ethernet NIO list on Windows.
New export to images (JPEG, PNG ...) that allows to export all the workspace (and not only what you see).
"Expand all" and "collapse all" features for the topology summary panel (contribution by beduev).
Annotations, rectangles and ellipses can be rotated.
On Windows, users can load an alternative gns3.ini by setting a path on command line, example: gns3.exe --configdir <path_to_dir_containing_gns3.ini>
New translation in Serbian (contribution by Veljko Dzodic).

Also, a lot of bugs from the previous version have been corrected. Concerning the virtual PC simulation, unfortunately this has not been included in this release but I've found a clean way to implement this directly in Dynamips, so be patient ;)

I'll like to say thanks to all our contributors, beta-testers and translators!

We hope you will enjoy this release.

Cisco image unpacker

admin — Wed, 19 Nov 2008 18:39:05 +0000

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.

New forum opened

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.

New tutorial for GNS3

admin — Mon, 06 Oct 2008 09:44:41 +0000

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!

Status of GNS3

admin — Mon, 06 Oct 2008 09:41:51 +0000

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!

GNS3 0.5 released

admin — Mon, 06 Oct 2008 09:39:23 +0000

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.
