I have a problem running python script via host command inside the Mininet topology code. I want run HTTPServer.py on h1 and host.py on other hosts, so that they can send HTTP requests to h1. The following is my code

...Build a mininet topology...

h1 = net.get('h1')
h1.cmd('python HTTPServer.py &')
for i in ...
    ho = net.get('h%s' % i)
    ho.cmd('python host.py &')

The Mininet executed without errors and it is running these scripts. But after for a while, it does not seem to be running.

But if I run HTTPServer.py and host.py through hosts via xterm, they can run without mistakes. I don't why they do like this.

You can add error log and check it after execution. Like this python host.py 2>error.txt & – mastisa May 27 '18 at 07:11
It's not about ryu, it's a mininet problem. Ryu is just a controller, mininet handle the host and network. – mastisa May 27 '18 at 07:14
No error. It just like that Httpserver does not send packets to hosts. – lanhai May 30 '18 at 01:46
