Hi, When trying to launch a simulation I get the attached error "Unable to connect to database: Cannot open connection" I know the back-end is running okay, as I have it open in another console. MySQL is running with a 'root' user configured properly and entered into the database preferences window. Any help is appreciated soon, thanks.

This is nor directly supported, but you could write your NeSSi2 extensions that do this. This will not be trivial since packets inside NeSSi2 are send in discrete steps and not as a continious flow like in actual networks. So you would need to come up with meaningful way to synchronize/handle this.

Is it possible to connect a network simulated in Nessi2 with a physical network? If so, how can I do that?

We are currently in the planning stages for a new project, but there is no development yet and I don't think anything will start this year.

Hi Bsufka, Many thanks for prompt reply. I found the Nessi project very interesting and user friendly. Is there a new simulator project under development?

We recently updated our repository server. Thanks for the hint that something is not working, we will investigate this. Just a warning, NeSSi2 is not actively maintaned at the moment, so a fix can take sometime and NeSSi2 and its dependencies are seriously outdated.

here's the solution , first you should set the 1-java enviroment like pic i've attached 2-set apache apache-maven-3.6.0 enviroment (describe in page 11 of manual nessi2) 3-run the backend (if it says can't connect or something like that you should turn off ur Local area connections , and add the loopback adapture then run it again ) 4-after backend says it's ready to go run the nessi.exe GUI in menu -> windows -> preferences ->> Nessi {{{{ important , in backend config set this ==>> localhost : 9999...

Hello. I am working on an Intrusion Detection System and I want to test it using nessi2. So, my concern is about how to intercept packets sent over a network so that I may analyze them. How can I implement the packet sniffing features within my application.

If I recall correctly, NeSSi2 includes an EchoClient and EchoServer application. So your applications may not show up, because those application names are already used.

Could you provide us the complete stack trace? The part of the exception above makes it difficult to locate were in our code the problem occured. One problem with communnication between and backend exists when both are run on the same computer and no active network interface (not even the loopback interface) can be found. Not sure if this is relevant for your case.

You can use the DDoSApplication. When you create a profile for the attacker, you have to add this application to it and configure it. At the very least you MUST add an IP address for the target. This address MUST exist in your network. On the target network node you MUST add an application that can receive packets send by the DDoSApplication. Since the DDoSApplication sends UDP packets, you can use the UDPServerApplication. Please make sure both applications have the same settings for the port number,...
