In the Virtual Voice lab series, I am using an Ubuntu Linux environment. To eliminate permissions issues, it is best that you run GNS3 as root.
Here are a couple issues I have experienced when running GNS3 as a normal user.
Not able to start dynamips.
Error msg: Can’t Connect to the hypervisor on port 7200
Not able to connect to a cloud object.
Error Msg: 206-unable to create Linux raw ethernet NIO
Error Msg: 206-unable to create Linux generic ethernet NIO
Error Msg: 206-unable to create UDP NIO
Here are a couple ways to run GNS3 as root.
- Use the sudo command:
- Open a terminal window
- Navigate to the gns3 folder. Example: ‘cd /home/josh/GNS3′
- Preceed gns3 command with the sudo command. ‘sudo ./gns3′
- Create a launcher icon
- Right click on the desktop
- Select ‘Create new launcher’
- Browse to the gns3 executable.
- Add ‘gksudo’ before the gns3 executable path.
