Hi all!

I did it! I have now multiuser GNS3 server running with following features:
  • Multiple users can simulate their networks at the same time regardless of each others
  • Packet Capture is working
  • Users can benefit servers CPU power and memory

Here are GNS3 features I haven't yet tested:
  • Using PIX (Pemu)
  • Connecting to real networks
Here are main points of my implementation:
  • Server is running Centos Linux (Because of I get support for this inside my company)
  • Users use VNC-viewer to connect server
  • VNC-server must be configured to allow multiple VNC sessions at the same time to different desktops
  • GNS3 is installed to server
  • There is many settings in gns3.ini file witch must be user specific
    Code:
    [GNS3]
    project_directory
    [Dynamips]
    hypervisor_port
    hypervisor_baseUDP
    hypervisor_baseConsole
    hypervisor_working_directory
    [Capture]
    working_directory

  • There is also common setting in gns3.ini such as hypervisor path, ios paths...

So I have to do couple of thinks when adding new user to the system:
1. Add linux user
2. Create GNS3 directories to the user and change permissions
3. Allocate hypervisor ports to user (ports cant overlap)
4. Create gns3.ini file according directories and ports from previous steps.

After that user can log in to system and GNS3 settings are in place already.


As you may notice I'm not using remote hypervisor feature at all. Main reason is that there is no support for projects when using remote hypervisor.

Hi,
It's great. Maybe you could write some tutorial after more tests.

OK and here it comes! Tutorial for GNS3 Multiuser environment.

Please notice that this is the very first tutorial of this kind of setup. Nobody has tested it yet. So I'm waiting your comments and problems to get this tutorial better.

Hi,

Here is new version of tutorial. I have corrected one bug. UDP incrementation is changed back to default 100 in new_GNS3_ini.sh file:

Code:
echo "hypervisor_udp_incrementation=100"


Example user settings list is also corrected. UDP base ports are crowing in 1000 steps now.

============================

• Edit /etc/X11/gdm/gdm.conf
sudo vi /etc/X11/gdm/gdm.conf

=============================

It is

/etc/gdm/gdm.conf

,right?


Hm is there something else to configure than in the tutorial? I did it exactly how you wrote it but my vnc client don´t connect to the vnc server :(

unable to connect to 192.168.*.*

kaage, good job. Can you tell me, what kind of resources (CPUs, RAM) do you have on the server for it to be able to handle multiple users?
