Ensure that it is enable

Ubuntu and Mininet Network Setup

Ensure that the mininet and ubuntu both are connected using the network host adapter that was created the previous. Note that the VM must not be running when creating this setting.

Right click the VM > Setting > Network > Adapter 2

Enable Network Adapter
Attached to: Host-only Adapter
Name: The name of the Network host adapter created

Theres no need to do any advance configuration

Mininet

Check your configuration by running ifconfig -a
Setup Virtual box Additional Setup
- Create dhclient
```
 sudo dhclient eth1
```
- Edit the /etc/network/interfaces file using nano
```
 sudo nano /etc/network/interfaces
```
- Add the following lines below the code
```
 auto eth1
 	iface eth1 inet dhcp
```
(OPTIONAL) SSH into mininet using putty ip: (Check your ifconfig) 192.168.125.104 port: 22

Test Mininet

Start Mininet
```
 $sudo mn
```
Check the nodes
```
 mininet> nodes
```
Check the network
```
 mininet> net
```
Check the nodes ifconfig
```
 mininet> h1 ifconfig
```
Ping h1 to h2
```
 mininet> h1 ping h2
```
Ping all
```
 mininet> pingall
```
Quit MN
```
 mininet> quit
```
Clear settings
```
 $sudo mn -c
```

Check Configuration on both VM

Run ifconfig on both VM
- Mininet
- Ubuntu
From this, we can tell that Mininet is hosted at 192.168.125.104 and Ubuntu is located at 192.168.125.103
Ping both side Run the following on both VM
- On Ubuntu VM
```
 ping 192.168.125.104
```
- On Mininet
```
 ping 192.168.125.103
```
  If its correctly configured, it should be pinged successfully

POX

Pox only runs on python2 so ensure that your not executing python3 at all times. The following test would determine if and if

Clone pox and use the correct version

 git clone https://github.com/noxrepo/pox
 cd pox
 git checkout fangtooth

Start Pox
```
 ./pox.py log.level --DEBUG forwarding.l2_learning
```
You should see the following sample output:

This means that pox controller is located at 0.0.0.0 for our Ubuntu but accessing it from outside would use <Ubuntu_IP> which in this case is 192.168.125.103
Start mininet

Since Ubuntu is running at 192.168.125.103, we would use it to connect our mininet vm with.
```
 sudo mn --controller=remote,ip=192.168.125.103,port=6633
```
Ensure that theres no space between the commas
Check your ubuntu

You should be able to see a new connection from your ubuntu pox controller. This means you have successfully connected both your mininet and your pox controller!
