Hi everybody, I'm traying to change mininet link properties but i can't. Anyone know some way to do it? For example after add "net.addLink(h1, s4, 0, 3, bw=100, delay='5ms', loss=0, max_queue_size=1000, use_htb=True )" in python script. There are any command to change the delay or the bandwidth with mininet running? mininet>---- Thanks
I need help with a network engineering assignment. Any chance you made a simpe switcth in python that, Key Task 1 Modify simple_switch.py to include logic to block IP traffic between host 2 and host 3. Key Task 2 Extend simple_switch.py to count all traffic going to and originating at host 1. Key Task 3 Create a rule in simple_switch.py that routes messages to the controller for topology maintenance.
Just save it anywhere and run it from the same directory .Ex" /home/mydir$ sudo python mycode.py " If you are using virtualbox, install xterm. run xming , run putty with x11 forwarding enabled. Now it will automatically catch any window like gedit or miniedit or wireshark.
'+fedora 2 1 What is the solution of 'Mininet must be run as root'? The user name and password for Mininet VM is mininet. I tried 'sudo' with command and used VM machine with sudo too.
Which Distribution are you using, if you are using Fedora, you need to be a real root user, which can be done as, for fedora/redhat/centos $ su - enter your root password and run mininet root@fedora21~#mn --topo=linear,2 --mac if you are using ubuntu, ubuntu has already sudo users enabled $ sudo mn on running above command, if the mininet complains, try to login as root user and run mininet $ sudo su - root@fedora21~#mn I think this will solve the problem
I am running ONOS-byon from "github.com/bocon13/onos-byon/blob/master/topos/onosnet.py".....by ./startmn.sh......but getting a message "Need to provide a topology and list of controllers".......Please tell me how do I resolve it.
good afternoon friend your videos very educational, it has served me well but I would like to know if you have knowledge miniedit, I would be helpful if you could raise a tutorial for installation and management.

how to store .py files and how to open the python interface in xterm?
Palash Bista I want to know that too :/
Just save it anywhere and run it from the same directory .Ex" /home/mydir$ sudo python mycode.py "
If you are using virtualbox, install xterm. run xming , run putty with x11 forwarding enabled. Now it will automatically catch any window like gedit or miniedit or wireshark.
Could you please tell me : How can i run the script when the python file is in the OS outside Virtual Machine?

Where are we supposed to store the .py files?
Mahima Vuppuluri Hi, you may store it anywhere. When you want to run it, just go to that directory and python it
I had the same question. What do you mean by "go to that directory and python it?"
/home/mydir$ sudo python mycode.py
You can follow steps on this page: www.wikihow.com/Create-and-Edit-Text-File-in-Linux-by-Using-Terminal
when i run sudo python filename.py , I am getting the error:
cannot import name createLink.
Can you please help me out? What am I missing.
