Create a preference file for yourself or for the devices that you want to use.
Make sure you include the .py extension.

The first thing you do after entering the Python shell is entering setpreferences():

   python
   from ixnetCli import *
   setpreferences('your preference file')
   
   connecttowindows() or connecttolinux()



Inside the preference file:
----------------------------
   apiServerType = 'windows' ;# Options: windows|linux
   windowsApiServerIp = '192.168.70.3'
   windowsApiServerIpPort = 11009
   linuxApiServerIp = '192.168.70.9'
   linuxApiServerIpPort = 443
   apiKey = None
   username = 'admin'
   password = 'admin'
   licenseServerIp = '192.168.70.3'
   licenseMode = 'subscription'
   forceTakePortOwnership = True
   deleteSessionAfterTest = False ;# For Linux only
   enableDebugTracing = False ;# Display error tracebacks
