Step 1: Open up Terminal for dependencies
sudo apt-get update
sudo apt-get install python
sudo apt-get install qt4-dev-tools
sudo apt-get install pyqt4-dev-tools
sudo apt-get install libncurses5-dev zlib1g-dev libsdl-dev libpcap-dev
exit

Step 2:Download GNS3 ver 0.8.2 and extract in /opt

cd /opt
sudo wget http://sourceforge.net/projects/gns-3/f ... z/download

sudo tar -xjvf GNS3-0.8.2-src.tar.gz
sudo rm GNS3-0..8.2--src.tar.gz
sudo mv GNS3-0..8.2--src /opt/GNS3

or you can download manually from GNS site (http://www.gns3.net/download/) .


Step 3: Create the following directories in Ubuntu:
These directories will be used by GNS3 – such as projects – where your working projects will be stored, cache, temp, IOS images, etc.

cd /opt/GNS3
sudo mkdir Dynamips
sudo mkdir IOS
sudo mkdir Project
sudo mkdir Cache
sudo mkdir tmp
sudo chmod o+rw -R ./Project
sudo chmod o+rw -R ./tmp
sudo chmod o+rw -R ./IOS

Step 4 :Download binary of dynamips and make it executable

cd Dynamips ie (/opt/GNS3/Dynamips)
sudo wget http://www.ipflow.utc.fr/dynamips/dynam ... -amd64.bin
sudo chmod +x ./dynamips-0.2.8-RC2-amd64.bin

Step 5: . Go to edit | preferences and in the ‘Terminal command:’ section type in:
gnome-terminal -t %d -e ‘telnet %h %p’ > /dev/null 2>&1 &

Step 6. Under ‘Paths’ change the ‘Project directory:’ to

/opt/GNS3/Project
and the ‘IOS/PIX/ASA directory:’ to
/opt/GNS3/IOS

Step 7. Click on Dynamips tab on the left
For the ‘Executable path:’ type in
/opt/GNS3/Dynamips/dynamips-0.2.8-RC2-amd64.bin

Step 8. Change the ‘Working directory:’ to
/opt/GNS3/tmp
Click on the Capture tab on the left

Step 9. For the ‘Working directory for capture files:’ change it to
/opt/GNS3/Project

Step 10 For Qemu

wget http://download.savannah.gnu.org/releas ... 1.0.tar.gz
tar xvzf qemu-0.11.0.tar.gz
cd qemu-0.11.0
wget http://downloads.sourceforge.net/gns-3/ ... h?download
First copy this line :> patch -p1 -i qemu-0.11.0-olive.patch
then this line :> ./configure --target-list=i386-softmmu
make
sudo make install



Change qemu path to /usr/bin/qemu and qemu-img path to /usr/bin/qemu-img

Tip: if u want to run ASA then run first “directory/qemuwrapper/qemuwrapper.py” in terminal

Hi ,

I am totally new to most of all .

My Systems information :

Ubuntu 11.10 64bit
GNS3 v .0.8.2


i follwed all the steps and went really good without any trouble ..

GNS 3 installation was successful . ----- Step - 1
Dynamips 64bit was cussessful ----- Step 2
Dynamips started on GNS3 ----- Step 3



Here is the problem starts on qemu : Step : 4

a . Downloaded the file file and patching files on home folder .
b . Extraceted and both folders and i copied files from Patch folder to pasted on the wemu folder .


Patching : Step : 5

FInally i found the solution for this issue


Qemu compilation and patching on Linux

Compiling Qemu on Linux (Ubuntu) is quite simple.

sudo apt-get install libncurses5-dev zlib1g-dev libsdl-dev libpcap-dev
wget http://download.savannah.gnu.org/releas ... 1.0.tar.gz
tar xvzf qemu-0.11.0.tar.gz
cd qemu-0.11.0
wget http://downloads.sourceforge.net/gns-3/ ... h?download
patch -p1 -i qemu-0.11.0-olive.patch
./configure --target-list=i386-softmmu
make
sudo make install

thx kartook for screenshot and making article up to date.

There are typo with ./configure -- (dash dash) which are replaced by simple dash, after applying patch.
Another typo at step 6 of patching 6. patch -p1 -i qemu-0.14.1_net_hpatch => 6. patch -p1 -i qemu-0.14.1_net_h.patch (missing dot)

Thanks for this howto !

Hi great post

which downloads should I get if I'm using Ubuntu 11.0.4 32 bit.

When I run "make" and then "make Install"
I get...

net/udp.c:80: error: ‘NET_CLIENT_TYPE_UDP’ undeclared here (not in a function)
net/udp.c:123: note: previous definition of ‘net_init_udp’ was here
make: *** [net/udp.o] Error 1

Kind regards

NetworkZeus

Did u patched the qemu with udp patch or not
