Ubuntu 14.04 LTS is due out on April 17th, but you can download the latest beta (the release candidate) at http://releases.ubuntu.com/trusty/ -- it should be pretty stable by this point.

Then, once installed and updated, install the following packages to prep for building/installing the latest Dynamips, GNS3 1.0a1 server, and 1.0a1 GUI --



(the python3-pyqt4 package will also pull in python3-sip package as a dep, which is also needed for the GUI.)

Then, download the latest Dynamips code from github - https://github.com/GNS3/dynamips/archive/master.zip
Unzip into the location of your choice (I made a "GNS3-1.0-alpha1" dir for these builds)

Then cd into the dynamips-master dir, and do

This should install dynamips into /usr/bin
Test it out to make sure it works:


Then we'll need to make sure that we have pip and setuptools installed for Python 3.x -- easiest way to do this is the following:


Now let's use pip to get some pre-req python modules for GNS3...


These will all download and compile code, and then install the resulting modules. The pyzmq one in particular will compile a lot of things, and warn early on that it can't find an existing libzmq installation -- that's OK, it will build it's own one during the compilation. Just let it run after the warning.

OK, now onto the new GNS3 server... Grab the server code from Github, https://github.com/GNS3/gns3-server/archive/master.zip
Unzip into the location of your choice, and then cd into the resulting gns3-server-master directory.
Then follow the instructions on the Github page to install it:


Now let's make sure that runs...

(Yes, it hangs at the last "exiting...", I use another Ctrl-C to terminate the process, which doesn't seem to hurt anything.)

Lastly, download and install the GUI --
Grab the GUI code from Github, https://github.com/GNS3/gns3-gui/archive/master.zip
Unzip into the location of your choice, and then cd into the resulting gns3-gui-master directory.
Then, follow the instructions on the Github page to install it:


Lastly, start up the server in one terminal window:


And then in another terminal window, fire up the GNS3 GUI --


Now, enjoy exploring new GNS3! :)

thx mate

As a side note, Ubuntu trusty has Dynamips 0.2.11 in the multiverse repository. I shall shortly be uploading 0.2.12 to the GNS3 PPA as well.

There may also be some more news regarding the packaging of Dynamips etc, in the coming days/weeks... Stay tuned!

Excellent :) thanks!

Just a few things.



I'll fix that.



Be careful, you were using a dev version, not the alpha1 anymore. It can be good or it can be bad ;)

YOLO :)

(They're all "dev versions" at this point, yes? ;)

This guide helped me a lot, but I needed some extra steps to get IOU working on 64-bit. I'm going to quote my post from another thread:



Also, don't forget iouyap. From the Debian Jessie guide:
"4 - Install iouyap
Download iouyap.tar.gz from: http://sourceforge.net/projects/gns-3/f ... z/download
tar zxvf iouyap.tar.gz
cp iouyap /usr/local/bin/iouyap"

Hello all;

I hope you are doing great;

Has some one face the following error message:

$ gns3GNS3 GUI version 1.0a2.dev1
Copyright (c) 2007-2014 GNS3 Technologies Inc.
---------Traceback lines (saved in exception.log)----------
Traceback (most recent call last):

File "/usr/local/bin/gns3", line 9, in <module>
load_entry_point('gns3-gui==1.0a2.dev1', 'console_scripts', 'gns3')()

File "/usr/local/lib/python3.2/dist-packages/gns3_gui-1.0a2.dev1-py3.2.egg/gns3/main.py", line 60, in main
raise RuntimeError("Python 3.3 or higher is required")

RuntimeError: Python 3.3 or higher is required


-- I already installed python 3.4 but I still get the same error when trying to start the gns3server and gns3.

Best regards;

I'm running ubuntu 12.04 64 bits, I am not totally new to linux but I am not a master.
If you can help me I would really appreciate it.

Here's a brief tale of my experience trying to get GNS3 1.0a1 running on Ubuntu 12.04 amd64: topic8984.html

I suppose it may be doable, but I for one ran out of time trying to get it to work... Hence using the beta (RC) of Ubuntu 14.04. That basically just worked.

Good luck,
Will

Thanks;

I give up, I'll download the Ubuntu 14.04 to see what happens.

Good Evening,

I just followed procedure mentioned above and it works fine on freshly installed Ubuntu 13.10.
Many Thanks for this instructions.

Regards,
UWillC
