Walk Through Example - Generation of Realistic Packets with ipktgen¶

In this example, we will use ipktgen to simulate the generation of realistic traffic in a computer network based on a sample traffic model and user-sessions file by following the outlined steps below.

Install using Installing ipktgen
Go to the directory:
```
cd ipktgen/test/test1
```

In the test directory, there are files that will be used as input into the traffic generation process, including app_model.json and net_xtic.json. You can open the files to see the format.

Open the net_xtic.json file and replace all occurences of the IP address 10.0.0.115 with the IP address of an interface on your device.
In a terminal window, run the command below to start all listeners (server ports) to be used in traffic generation process:
```
sudo ipktgen -v -s  -a ./app_model.json -u ./net_xtic.json -o ./test1_out -m Type4
```

or:

sudo ./test_server

On a different terminal window, run the command below to start the realistic traffic generation process:
```
sudo ipktgen -v -c  -a ./app_model.json -u ./net_xtic.json -o ./test1_out -m Type4
```

or:

./test_client

This will generate packets based on app_model.json, and net_xtic.json. The traffic generation process terminates on the client side once all traffic baased on the supplied input files have been generated.

Attention

Each process should be terminated at anytime with ctrl+c. Please ensure that the client processes are terminated before the server processes.
