To Login a Mininet Node

Because it doesn't have a GUI window, we can not use mininet's (g|x)term command.
You can use the ./contrib/term.sh script in another terminal instead.

• Open another terminal.
• Then,

$ vagrant ssh
[bargee@barge ~]$ /vagrant/contrib/term.sh h1
root@<h1>:~# 

• Or if you have Docker client in your local machine, you can log into the node directly.

$ ./contrib/term.sh h1
root@<h1>:~# ifconfig
