How to use Inet's FlatNConfigurator in Omnet++

[Lenny Linus]

Hello there people! I am a beginner in Omnet++, i do not have an in depth knowledge about it. I am following a book on omnet++ and Inet. There is a small simulation inside in which a basic network consisting of a server node, a client node and a router is present. The books tells me to add a FlatNetworkConfigurator to my Network. When i do so before running the simulation, i get an error saying 

"Error in module (IPv4NodeConfigurator) Ethsit.pc1.networkLayer.configurator (id=12) during network initialization: Configurator module 'configurator' not found (check the 'networkConfiguratorModule' parameter)."

I searched and a solution said to add the line  ' **.networkLayer.configurator.networkConfiguratorModule = "" '. But after i did that there came another error 

this time it said "Error in module (EtherMACFullDuplex) Network.server.eth[0].mac(id=21 ... " I have attached a screen shot... Have a look, i would be thank ful if anyone can solve this for me.

1.- The module name flatNetworkConfigurator should be “configurator”

2.- Ethernets gates must be connected using channel of the type ChannelDataRate, they can’t be connected without channels.

Thank you so much for the reply! Can you tell me exactly how do we connect the two nodes using "ChannelDataRate" 

After you said i did connect the nodes and the router using a DatarateChannel, But the problem still persists. If i use a FlatNetworkConfigurator it says "error: cannot cast 'FlatNetworkConfigurator*' To 'IPv4NetworkConfigurator *'" something... I have attached both the package.ned and omnetpp.ini files please have a look at them and guide me. Thank you! :)

Alfonso, Hi

The answers do not help in resolving this problem and honestly I have no idea how to finally get started with omnet. Moving away from NS2 I have found it frustrating to build even simple simulations with omnet. I cannot find a clean and straight tutorial and I cannot understand the error messages.

I have 2 StandardHosts (connected with an Ethernet100 cable) and I still get this error:

Error in module (IPv4NodeConfigurator) Network.standardHost.networkLayer.configurator (id=11) during network initialization: CheckAndCast() : cannot cast (FlatNetworkConfigurator *) Newtork.configurator to type "IPv4NetworkConfigurator *)

Thanks

Why don't you switch your "configurator" to the type that OMNeT complains about?

import inet.networklayer.configurator.ipv4.IPv4NetworkConfigurator;
...

configurator: IPv4NetworkConfigurator {
...

Take a look at the NED files in the configurator folder, they include explanations on their behavior and restrictions and so on.
