OK, so you got IOU working, but what about the regular routers we are used to like we did with GNS3 0.8.6? No fear, we got you covered!
If you got to this part, your past the “hard” part of installing GNS3 1.0 ER. Next, we’ll need to run a few commands to actually install dynamips on our Debian box. Note I also got this from the GNS3 forums — http://forum.gns3.net/topic8988-10.html


To do this, open up a terminal window and type in the following commands to install each piece of dynamips. If it prompts you “Yes or No” hit yes.

apt-get install libelf-dev
apt-get install uuid-dev
apt-get install libpcap-dev
wget https://github.com/GNS3/dynamips/archive/master.zip

If for some reason your not comfortable using the wget command, just manually open up a browser and download the file like you normally would. I like to place these files on my desktop, so browse via the terminal to the cd /Destkop and type in unzip master.zip to unzip the file. Now, lets go to that folder via cd dynamips-master and type in make and then afterwards move these files to the dir /usr/bin/dynamips by typing mv dynamips.stable /usr/bin/dynamips

You may need to be the root user to run these commands, so before you start issuing them type in su and type in your password.

Once you got that done, now we’re in familiar territory. Open up GNS3 and then go to EDIT > PREF > DYNAMIPS > and under the Path to Dynamips browse to our dynamips file. In our example above, we put it in /usr/bin/dynamips. Browse to it and then hit OK.


Lastly, go to IOS ROUTERS and browse for the images that you normally used in GNS3 0.8.6. Poof! Routers and IOU Switches in our topo!
