I would like to run a python file on the default Mininet host h1, which alters the IP address of h1 and sends data from h1 to other targets.
How can I do this?
On the Mininet command line, changing the IP address is done as follows:
py h1.setIP('Ipaddress').
What I would like is:
h1 run_python_file new_ip
which would change the IP address of h1 to new_ip, create a socket, and send random data to a destination.
You can run a script at host h1 by first navigating to the directory of the script and then running h1 python3 nameOfScript.py.
You can think of h1 as a Linux machine, so running a Python script needs to be done via the python3 command. Here is another example:
*** Starting CLI:
mininet> h1 python3 hello.py
hello world
mininet>
I created a hello.py script and started Mininet from the same directory by running sudo mn, then I can called the script.
You can pass the new_ip argument to the script as per Python's docs.
