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.
Installing GNS on Ubuntu 7.10 is as simple as:
1) Download GNS3 source files
2) Download dynamips binary for linux
3) Change the dynamips binary to allow execution.
4) Double-Click gns3
5) Set the location for the dynamips binary in the GNS3 preferences.
6) Add an IOS image to the GNS3 IOS library
7) Create your LAB
Enter emulation mode.

Great instruction! I had just installed Ubuntu 7.10 in my laptop and I can run my first router in less than an hour. Thanks.
One thing you should mention is unzipping Cisco image s with “unzip -p compressedimage > regularsizeimage”
as dynamips software author mentions in his web page.
Thanks.

I have a problem. when I test dynamips, i get failed to start dynamips.
Could be a permision problem? I have followed everything else in the tutorial.
Not a linux guru and have searched the web but not sure how to debug this further.
thx

@Duane
Can you navigate to the directory containing the dynamips file and send the output of the ‘ls -la’ command?

@Duane,
The permissions look ok to me. Which of these versions of dyanamips are you referencing inside GNS3? - Josh
May 20th, 2008 at 12:59 pm
i have used both. I am currently pointed to the 2.7.
I also just noticed I am running the 64 bit version of ubuntu.
thanks
May 20th, 2008 at 3:20 pm
@duane, 64-bit could definitely be the problem. Do you have another machine running 32-bit? - Josh

sorry for the delay in replying. I downloaded the latest non 64 Ubuntu and Gns3 and have things up and running.
now my next goal of getting my two 4 port ethernet nics and 4 usb adpaters recognized so i can map them to the my lab switches.
thanks for the help Josh.

Hi Josh,
It always a pleasure to visit blindhog.
Thanks to your tutorials, I’m quite proficient with using Dynamips, so I haven’t been really interested in GNS-3; however I decided to watch a couple of your GNS-3 videos and I was convinced that GNS-3 is definitley the way to go.
My only question is this:
Have I got to unintsall Dynamips and Dynagen currently running on my Ubuntu Server? Or can I just point GNS-3 to the Dynamips Binaries?
Thanks a Bunch!!!!
Rgrds,
Ayo
