Starting Multiple Network from Command Line

The command line Network Simulator is purely NON-GUI and uses only character user interface for obtaining various inputs for the simulator. It can be invoked by executing the StartNetwork.bat/sh in <Simulator Home>/bin/cmdline directory. Using this utility, you can start a single network or multiple networks, from command line by specifying the name of the network created with the Network Designer tool.

Starting Network Simulation in Windows

To start Network Simulation in windows, type the following command from the <SimulatorHome>/bin/cmdline directory.

StartNetwork.bat -net .\networks\samplenetwork -m <specify debug level as 1 or 2> -l <to log the messages>

Starting Network Simulation in Linux

To start Network Simulation in Linux OS, type the following command from the < SimulatorHome>/bin/commandline directory :

$ Sh StartNetwork.sh -net ./networks/samplenetwork -m <specify debug level as 1 or 2> -l <to log the messages>

Note:

1. The details of the Database server name, Port number, User name, Password and the Server path is stored in database_params.conf file in <SimulatorHome>/conf directory. You can make the required database settings in this file.
