The following command will start the container and run all validation tests

• docker run -it ekiourk/ns2 ./validate

Usage

By running the following command you will get a prompt from ns2 waiting for instructions

docker run -it ekiourk/ns2 ns

To run a local tcl script from inside the container.

1. Create a tcl script or download one using wget http://nile.wpi.edu/NS/Example/ns-simple.tcl locally

2. Run docker run -it -v $PWD/ns-simple.tcl:/ns-simple.tcl ekiourk/ns2 ns /ns-simple.tcl by using the -v flag to put the script from your current directory inside the root directory in the container

Run tcl script with nam.

1. First run container with bash in order to get a prompt inside the container. Make sure you mount the X11 socket and set the DISPLAY environment variable docker run -it -v $PWD/ns-simple.tcl:/ns-simple.tcl -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY ekiourk/ns2 bash

2. After you are inside the container run ns /ns-simple.tcl and NAM should open ready to animate the simulation

If there are problems starting NAM then try to set the argument --cap-add=SYS_ADMIN and run xhost local:root on the host
