As mentioned in an earlier post GNS3 is moving ahead fast. Currently at version 1.2.1 the GNS3 is looking great. Compared with the version 1.0 Beta 1 which I had installed, the 1.2.1 is not only more stable, but it has the Menu more clean and compact. For example now there is only one Preferences menu where you can adjust all your settings.
During the installation of 1.0 Beta 1 I made some notes in Evernote and it prove to be very useful as the installation was pretty messy. With 1.2.1 I did the same thing, but the installation was very smooth. Still, I said that if I made those notes maybe I should share them for those interested in a quick installation. A more complete guide can be found on GNS3 Community.
1. Download GNS3 1.2.1
Head over to http://www.gns3.com/, create and account and download the bundle archive for Linux.
If you for some reason you don’t want to create an account, you may download each package individually from https://github.com/GNS3
The following lines will assume that you have the bundle archive.
2. Install Ubuntu 14.04 dependencies
$ sudo apt-get install libpcap-dev uuid-dev libelf-dev cmake $ sudo apt-get install python3-setuptools python3-pyqt4 python3-ws4py python3-netifaces python3-zmq python3-tornado $ sudo apt-get install unzip
3. Unzip the bundle archive
$ unzip GNS3-1.2.1.source.zip
You should see 5 packages in GNS3-1.2.1 folder:
4. Install Dynamips
$ unzip dynamips-0.2.14.zip $ cd dynamips-0.2.14 $ mkdir build $ cd build $ cmake .. $ make $ sudo make install
To check if the correct version is install:
$ dynamips | grep version
You should see in the output 0.2.14
5. Install GNS3 Server
$ unzip gns3-server-1.2.1.zip $ cd gns3-server-1.2.1 $ sudo python3 setup.py install
To check if the GNS3 Server is installed correctly:
If you see some output other than an error, than you’re fine.
6. Install GNS3 GUI
$ unzip gns3-gui-1.2.1.zip $ cd gns3-gui-1.2.1 $ sudo python3 setup.py install
To test if the installation is working:
You should see a graphical interface of GNS3 launched.
At this moment you have a working GNS3 environment if you want only want to test Cisco hardware emulators. I strongly recommend to continue and install also the rest of the components. Who knows when you’ll need them
7. Install IOUyap (Optional, if you will use IOU images)
$ unzip iouyap-0.95.zip $ cd iouyap-0.95.zip $ make $ sudo make install
To test the installation:
$ iouyap -h
If you encounter an error, please check the [Update 1] section at the bottom of this article.
8. Install VPCS (Optional, if you want to use VirtualPC)
$ unzip vpcs-0.6.zip $ cd vpcs-0.6/src $ ./mk.sh 64 $ cp vpcs /usr/bin/
For the third line, the 64 represent 64bit, as my Ubuntu 14.04 is build on 64bit.
The values can be:
– 32 or i386 for 32bit OS
– 64 or amd64 for 64bit OS
Please be sure to use the correct one for your OS.
To test the VPCS:
You should see a Virtual PC being launched. Leave the console with letter q.
9. Install VirtualBox (Optional, if you want to launch VMs)
Download the correct version for your system from https://www.virtualbox.org/wiki/Linux_Downloads. The following lines will assume an Ubuntu 14.04 64bit OS.
$ apt-get install dkms $ dpkg -i virtualbox-4.3_4.3.20-96996~Ubuntu~raring_amd64.deb
You can also use the instructions at https://www.virtualbox.org/wiki/Linux_Downloads and go for an APT installation.The choice is yours.
10. Install Qemu (Optional, if you want to use qemu images)
$ sudo apt-get install qemu
11. Install IOU (Optional, if you want to use IOU images)
I’m not a legal matter expert, and the usage of IOU is sort of grey area. Because of this, I’m not going to cover this chapter.
You’re ready to go. Start the GNS3 GUI:
Some things to check before going live:
- check in the menu Edit > Preferences to set your desired Paths (in General sections) and to check the paths for the binaries (dynamips, vpcs, iou, virtualbox…)
- add the IOS, virtualbox vm, iou images
- in case of Cisco hardware emulators don’t forget to find the IdlePC value (when you add the IOS image or later with the start of your first router with a certain image) otherwise your CPUs will cry.
If something does not work as described or you need help please let me know in Comments.
If you get the following error during installation of iouyap:
GNS3-1.2.2.source/iouyap-0.95 $ make gcc -g -DDEBUG -Wall -c -o iouyap.o iouyap.c iouyap.c:40:23: fatal error: iniparser.h: No such file or directory #include ^ compilation terminated. make: *** [iouyap.o] Error 1
Try to install the iniparser as follows:
sudo apt-get install flex bison
cd /tmp curl -L https://github.com/ndevilla/iniparser/archive/master.tar.gz | tar -xz cd iniparser* make
and finally iouyap
cd /tmp curl -L https://github.com/GNS3/iouyap/archive/master.tar.gz | tar -xz cd iouyap* bison -ydv netmap_parse.y flex netmap_scan.l gcc -Wall *.c -I /tmp/iniparser*/src -L /tmp/iniparser* -o iouyap -liniparser -lpthread strip --strip-unneeded iouyap sudo mv iouyap /usr/local/bin
