At the time of writing, the latest version found through the official Ubuntu repositories is 0.10.1, which is what i had installed too:

xxx@ubuntu:~/Desktop$ dynagen --version
dynagen 0.10.1.090807

But there are many cases that you won’t find it in Synaptic, especially the beta versions. So go to dynagen site and select one of the following:

If you click on the “Interim Builds” link, you’ll see a local page with all the current beta/alpha versions, if there are any. Download the latest rpm file.

If you click on the “Download” link, you’ll be directed to Sourceforge.net for the official stable builds where you’ll have to download the latest rpm file.

Usually, new beta versions are appearing in the “Interim Builds” section and when after a while they become stable, they are moved to the “Download” section.

Latest version at the time of writing is 0.11.0 (which is not available through synaptic). So proceed and download “dynagen-0.11.0-1.fc9.noarch.rpm” from sourceforge.net in a local directory.

In order to install it, you must first convert it from rpm to deb, using the alien program. So get the alien program through Synaptic or apt-get.

xxx@ubuntu:~/Desktop$ sudo apt-get install alien

However, you should keep in mind what the alien man page says:

“alien should not be used to replace important system packages, like init, libc, or other things that are essential for the functioning of your system. Many of these packages are set up differently by the different distributions, and packages from the different distributions cannot be used interchangeably. In general, if you can’t remove a package without breaguide your system, don’t try to replace it with an alien version.”

Then move to the directory where you saved the latest dynagen rpm and run:

xxx@ubuntu:~/Desktop$ sudo alien -k dynagen-0.11.0-1.fc9.noarch.rpm
dynagen_0.11.0-1.fc9_all.deb generated

-k is used so the version number is not increased. Alien by default increases it.

Now you have a deb package. You can use deb-gview (get it through synaptic/apt-get) in order to view its contents (plus the install locations).

xxx@ubuntu:~/Desktop$ deb-gview dynagen_0.11.0-1.fc9_all.deb

Finally, install it using dpkg:

xxx@ubuntu:~/Desktop$ sudo dpkg -i dynagen_0.11.0-1.fc9_all.deb
Selecting previously deselected package dynagen.
(Reading database ... 127883 files and directories currently installed.)
Unpacguide dynagen (from dynagen_0.11.0-1.fc9_all.deb) ...
Setting up dynagen (0.11.0-1.fc9) ...

And check its new version after it has been installed:

xxx@ubuntu:~/Desktop$ dynagen --version
dynagen 0.11.0

You can also use the following if you want to automatically install the package after converting it:

xxx@ubuntu:~/Desktop$ sudo alien -i -k dynagen-0.11.0-1.fc9.noarch.rpm

To allow complete simulations, GNS3 is strongly linked with :

• Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.
• Dynagen, a text-based front-end for Dynamips.
• Pemu, a PIX emulator.

GNS3 is a excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.

It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers. This project is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.

Features overview

• Designing high quality complex network topologies.
• Emulating Cisco routers and PIX firewalls.
• Simulating simple Ethernet, ATM and Frame Relay switches.
• Load and save in Dynagen’s INI-like format.
• Image export (JPEG, PNG, BMP and XPM).
  

Important notice: users must provide their own Cisco IOS to use GNS3.

The principle of dynamips is to simulate hardware platform of CISCO Router, run CISCO software directly, and to achieve almost complete simulation of CISCO routers and switches effect while dynagen is to make it more convenient for you to use and the configuration more humane on the basis of dynamips. This paper is an instruction for dynagen to use dynagen in windows xp. In addition, its use and configuration in Linux and other platforms is basically the same. You can use this software on the basis of this paper to achieve simulation running of numbers of routers on single or more PCs and to realize their interconnection. This is helpful for you to study CISCO router figuration on network. This is the supplementary information about running numbers of routers on one or more PC (windows) and realizing their interconnection. The latest version can support switch module, but temporarily I don

Dynagen runs on any platform that supports Python, which is to say nearly any platform. I have also put together a Windows installer package that includes Dynamips and provides a compiled version of Dynagen, eliminating the need to install Python. It also provides Explorer
