Automate mininet to run batch commands

If you prefer to use mininet console instead python API, maybe you will need automate the process to run batch commands.
With source command you can load a file with all commands to execute inside mininet, like this:

source init.cli

This is the content of init.cli:

py "Configuring network"
h1 ifconfig h1-eth0 10.0.1.1/24
h2 ifconfig h2-eth0 10.0.1.2/24
py "Current network:"
net
dump
py "Adding switches to the controller"
sh ovs-vsctl set-controller s1 tcp:127.0.0.1:6633
sh ovs-vsctl set-controller s2 tcp:127.0.0.1:6633

 Enjoy it!

Exception: Could not find a default OpenFlow controller in Mininet

If you try to run a mininet script like this  , maybe you will get this problem if you are under Ubuntu.

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode
